Metageographic Pavement

Seeking direction in the coronavirus pandemic, isolated amidst escalating anxieties, increased vulnerability to a virus crossing borders brought a vulnerability our infrastructures seemed more than ever to be unable to sustain. The danger of introspection was tempered by alarm, as a shock at the unaccustomed sense of the evanescence made far less remote stories of plagues, as we turned to their pasts to process the new normal of pandemic life. Trapped in tenuous relation to the present, walks offered a new release into a new temporality, and escape from a temporality of mortality that seemed to be a countdown to something new: and if many turned to trees as the sentinels of monuments to a more living present, as if in a combination of the historian and flâneur, I started to seek out imprints of the contractors and pavers who had covered Berkeley’s and north Oakland’s residential communities over a century ago with pedestrian pavement. Each print provided evidence of their arrival, from the century’s start of the century, through the 1940s, in booms of post-war expansion beside wartime stamps. Such “points of historical interest” seemed a form of creative tourism, as we were seeking tangible signs of a sociable present that was frayed. As much as trees, these provided a new way of thinking about time, of living with radical uncertainty, and of seeking a foundation by securing existential as much as epistemic stability in such uncertain times.

Was this new age of pavement, of restricting housing and covenants, or a sort of sociability among the ghosts of lost neighborhoods and communities, made poignant in an era or episode of increased social distancing by its very materiality? Searching sidewalks for these traces of human settlement seemed an act of resistance to the tracing of patterns of mortality we watched every day. As infection rates rose, and we were immersed in a real-time reaction to a pandemic, sidewalk walking passed was adventure in an age of social distancing. As COVID-19 made us enter another period of anxiety unlike the recent past, new viruses sending us to the seventeenth century, contemplating these names seemed fossilized traces of previous moments left in the cement of my Berkeley neighborhood provided a tactile story that seemed necessary to embrace. Paradoxically, I had long read these stamps without much attention to dates, or to their temporal remove. But the proximity of these long dead men whose imprints lie across Berkeley and Oakland, perhaps more than other cities, gained new legibility, or acquired a legibility to me as I walked around a bit aimlessly, looking for orientation, and finding it, surprisingly, not on a screen but underfoot. While the prints near my own house were mostly from the 1930s, along Shattuck Avenue, finding multiplied sites of “historical interest” seemed a mending or attending to the community, able to be imagined as in the public interest.

The return to walking during the pandemic–fed by a rather shell-shocked need for processing, for finding connections, or restoring deeply stressed and frayed ones, made the elegant crisp lines of stamps pass for forms of sociability certainty, and encounters, as if one could assemble the history of paved space with a certainty that was revealed far more clearly than the new period unfolding in real time.

I didn’t know anything about F.E. Nelson, but the escutcheon of the contractor whose work from as early as 1910 off Piedmont Ave. that continued on sidewalk stretches through the 1920s seemed a line of time that placed a sense of history into the stretches of cement that they poured and smoothed for individual homes, material traces of urbanization and built space that paralleled the start of an anthropogenic period of the paving of land in the Bay Area that marked the end of an earlier nature of land use and the carving of space into neighborhoods that might be seen as a form of settler colonialism and possession, cementing a sense of an ending to the indigenous land use practices studied in Berkeley by Peter Nelson (no relation as far as I know), taking ownership of residences in an urban agglomeration of the past, if one of far less density or land value than today. As an era of ever increasing percentage of pavement and resurfaced space across northern California, and the Bay Area, detecting hints of the first paving, a century ago, that began to shift earlier notions of land use, offered more than a sense of psychic stability.

It was a material record of a past presented with some reassurance to the pedestrian that the ground was solid. The apparent antiquity of these markers of early paved surfaces, not resurfaced for over a century in a pocket of relatively low real estate development and mobility, became not a sign of privilege but reassuringly comforting as a continuity of a bedrock of shared life, or a solid sense of place, in the past lives of pavers whose names I had not noticed often but seemed to compensate for empty streets in a state when the Shelter in Place policy and work from home ethos reduced foot traffic, some of which had blurred the sidewalk markers left in concrete by contractors as a sign of their skill in engineering pedestrian space. It seemed a form of writing or inscription that evolved in some sense since the more rudimentary public lettering of some earlier dates–a stamp of 1907 was among the earliest near by house–on Woolsey Street–if an early evidence of a distinct modernism of the start of paved life.

These inscriptions stamped in the pavement of old contractors–“sidewalk stamps,” many have it, or simply “imprints”–were always something I had overlooked. But if Robert Musil argued in prewar Europe that the remarkable thing about the intentional urban monument was that it was something that went unseen–“that one does not notice them;” that “there is nothing in the world that is as invisible as a monument”–and that their impact receded as they became part of an urban landscape, as if displaced by the media environments of the twentieth century as outdated in their materiality, these stamps gained an unforeseen monumentality as they seemed far more human than the monuments of escalating rates of infection, mortality, and jaggedly time-series graphs of mortality that broke parameters with regularity. The monuments seemed more human, more impressive, as a site of the lived environment I had somehow overlooked, so that even feint imprints, worn by the feet of past pedestrian traffic, seemed to stare back at me, in some recognition, from a temporal divide, as evidence of a pedestrianized space of the local past. If set by homeowners, to be sure, several of the imprints seem relics of a. past I could not fail to see as staking out the pedestrianized spaces of other pasts as I walked to a volunteer shift, offering access to a different sense of place from the U.S. Depression, barely left on their footworn surfaces. I was perhaps too ready to interpret as a marker of older pedestrian paths that were once walked down.

Few regarded these imprints as monuments–if, as I saw with some surprise, years later, the imprint of the very same firm that had paved sidewalks in my neighborhood off of Prince St., the Oakland Paving Co., had not only paved sidewalks deep into Berkeley in the early twentieth century–

2201 Woolsey St., Berkeley CA

–had indeed merited museumification as a historical relic and as a monument–in the driveway to the colonial revival residence I found housed the Berkeley Historical Society, housed in an old turn-of-the- century 1902 gated house close by the university in one of Berkeley’s first residential districts–as if the Society had by its good graces preserved this old relic, of a slightly different font of a stamp, maybe dating from different date, that seemed to confirm its archeological value as a marker–the lettering used in an imprint stamped 1911 up the street from my home, without inverted “n”‘s or a uniform font.

But the following of the evidence of what I took as a pedestrianized spaces of the sidewalk seemed a humanization of space, in a time of existential estrangement and uncertainty. As I walked in horror at escalating mortality rates, the names popped out as if they gained status as unrecognized improvised memorials–as much as humanized space. The shift reminded me of the effect cultivated intentionally in literal “stumbling blocks,” or stolpersteine, placed in urban pavement in Berlin and, later, other German cities, as monuments that gained such immediate relevance that they spread to Belgium, France, Italy, Poland, Hungary, Moldavia, Lithuania, Slovenia, Croatia, and Ukraine. These stones, set in existing pavement to make walkers “stumble” in a pavement of memory, to pause and read least we fail to recognize the scale of loss of former inhabitants, were at least operations. As I payed respects to F. E. Nelson, for example, or the paving of Fulton Street’s few houses, this was almost better than a novel; to be sure, he was never violently and systematically evicted with force, or killed with his family, but the record Nelson left on the ground, or the man in his crew who inadvertently inverted a letter in his name, seemed insight to a moment in an early manmade past. Was the same man unsure what year it was, 1900 or 1920?

But these were not names of such living ghosts, if left without the intentionality I started to invested in them. I imagined an Oakland aristocracy on the scriptorium of the sidewalk, as I came to recognize as an aristocracy of the pavement, those artisan families of the venerable Schnoor, the generations of Greek pavers of the Salamids, from Frank to A[nthony], or the Oakland Paving Co. The city of Berkeley has long passed costs of repaving onto home owners, and the process of paving was on most residential neighborhoods done piecemeal, residential house by residential house, for the most part, rather than, as in many cites, by urban planners: the traces of voices of the past seemed, as ghosts to be alive in new ways, paradoxically, in the emptier sidewalks I navigated in the pandemic, as I turned to them for signs of life in what felt like a project of excavating lived space as living space had suddenly contracted.

Was there a sense of self-reliance of the most odd search for virtue, in this identification of the lettering of pavers’ signs? If the ornate frames of some might reveal the prosperity after World War I, when the escutcheons of pavers seemed to court the art nouveaux, as did some older service building facades, the intact notion of many of these signatures in the cement seemed like signs of turning to face the present, or to face an other, or enacting a sort of conversation at a time when conservations were so stressed. This was a sense of a deep history lying flat for any pedestrian on the sidewalks pavings that were done for single homes in Oakland and of particular historic density in the neighborhood where I had moved, where I didn’t know the names of neighbors as much as the contractors who had surfaced the sidewalks. These names, like imaginary memoranda, seemed missives from a forgotten era, providing something of a counter-map all of a sudden before the maps purporting to track contagious spread of COVID-19, spikes of mortality rates from New York City and other global hot-spots, that sent a shuddering x-ray of sorts on the social order of the nation.

If the scrivener was the lowliest order of scribe, often overlooked, as administrative copyists who seemed to embrace the role embracing public servants, notaries, scribes, accountants and petitioners of an earlier era, before a current era of specialization and deputized proxy, the names pressed in the pavement were akin to witnesses of the spread of private housing beneath the open skies of the Bay Area. And if ominous markings of stenciled black spray-paint had alerted pedestrians in North Oakland to the sites of black-owned houses in communities of African American homeownership, the sidewalk imprints served as scribal residue of reminders of the shifting grounds of home ownership, that I became increasingly attuned to tracking in the pandemic, as remaining signs of a tangible relation to the past, least it be lost, in an era of increasing insecurity so that one didn’t have to feel quite so rudderless.

It was in the pandemic that I discovered how many had curiously remained legible underfoot, untouched by the spate of remodels, in many blocks of Berkeley and Oakland, offering a tangible collective testimonial of the past, that seemed suddenly reassuring as an act of bearing witness, when we were uncertain of what we were bearing witness to. As the testimonies of the lowly scriveners who produced a volume of work that went unseen under the the edifice of legal productions they sustained, as the description of the copying clerk hired to “prepare an extraordinary quantity of deeds to copy” who impressed his employer by his “modest, quiet, gentlemanly demeanor, and his intense application to his duties” evoked Bartleby the Scrivener, for Melville, the dates names seemed a form of public writing to sustain the city of an earlier era, to which I might have escaped or placed myself at an angle to the present.

These scriveners of cement traced the block-by-block settlement of Berkeley. long before its gentrification, perhaps, but anticipating it in personal stretches of sidewalks of grades of cement from different local quarries,–they could not prefer not to, but they etched urban social stratification. in ways that anticipate our own era of increasingly starkly drawn social inequalities. If I had tried to gain a moral compass in relation to the increasing deaths that were evident, say, in the creation of the largest mass grave in Hart’s Island in New York City, the site of burial of unclaimed bodies of those kin or without family relations. As the oldest site for the burial of the unclaimed and poor for over a century was opened again as a resting place for the unclaimed victims of COVID-19, the reopened cemetary legally owned by New York States’s Prisons, was emblematic of the loss of life and deep wound that the pandemic placed in the city where I grew up, on another coast, where few sidewalks bore any name.

The mass grave in this new Potter’s Field was emblematic of the early modern nature of our collective confrontation with mortality and disease, in those days when the principles of infection or possibility of vaccination was remote. A sign of the utter failure of community, or of communal practices being stretched to the breaking point, and unprecedented stress placed on our system of public health, the sense of a need for finding home and community and the face-to-face–all those targets of Weberianism–emerged at full force. In contrast, the names on the ground each morning or late afternoon walks were not only a way of marking space, but ordering time.

I was reading the names of these pavers, strikes were long left on Berkeley’s sidewalks, were tabulated as part of its distinctive built landscape, as points of contact less overwhelming, as small drops of mortality, as it were, less overpowering and more measured, if as intense, that tied me to a world before. the so-called Spanish Flu, and to the work lives of a measured past as a way of restoring a face-to-face community I was without. If the sidewalk became a sort of re-enchantment of space, it was a form of mapping, or remapping, by reading old traces stamped in concrete, spatially sorted out as traces of the city past in very human signage of the earlier century.

We could only stare, open-mouthed, at the visualizations aptly showing the ballooning infection and mortality rates by growing red splotches, akin to the blood coughed up by tubercular patients, along the map. All the while trying to grasp the scale of death and their rate of growth, we contemplated the possibility of ever “flattening the curve,” but were often even gawking as a passive spectator of dashboards of exponentially growing cases, like the first observer of a new mortality map. The effect was a bit disarming, like loosing our purchase or indeed stability or being, like historian of science Lorraine Daston put it, feeling one’s way in the dark like an early modern scientist, wondering if we had any purchase on how infections spread. The sense of place seemed to deepen, however, not only because we traveled less in California, where we tended to shelter in place, and even the ambient noise of car traffic fell, but we developed something like a new sense of place, perhaps as a reassurance given the insecurity of most maps of infection the news cycle seemed to blare. In their place, the names etched, stamped or traced by framed imprints seemed to gain volume, as if to echo the building of old space,

As if remembering the intentionality of a “need to walk,” to explore the areas where we live,” imagining a destination we were approaching, even if we did so without having anything so precise or fixed in mind, we seemed to disengage from the GPS in healthy ways while traveling more on foot. Rebecca Solnit found a sense of place serves as a “sixth sense,” and described the need to cultivate “an internal compass and map made by memory and spatial perception together,” in Savage Dreams–an important book on the landscape wars in the American West that describes the relation to the landscape as a form of civil disobedience. The time-stamped sidewalk stamps that I began to notice in new ways as they seemed to speak to me around the sidewalks of Berkeley, CA seemed a compass on a pandemic by returning attention to an imagined if real local community of the long dead, in which I tried to find some stability as our web social contacts shrunk. Walking in my neighborhood, I was remotely observing a flurry of activity of residential sidewalk paving–at a temporal remove was an act of cultivating that sixth sense of spatial perception, finding forgotten landscapes and a surprising sense of spaciousness in the scriptorium of the sidewalk, developing an almost unhealthy focus on the materiality of names set in cement more than a century ago as if they offered a reassuringly material past. The stamped icons were often almost baroque, art deco, or geometric forms, seemed haiku paring name and date, as if one could trace some hidden web of work set on sidewalks in the lost reality of years past.

As much as I wanted to critique the present, the amount of information–and lack of it–overwhelmed. Could one adopt a clear critical stance by removing oneself from newsfeeds? The absence of walking on the streets seemed a zen-like reprieve from online stress, there were far fewer aperçus of the urban to discover in questing about with one’s eyes alert to the surroundings, but the sidewalk stamps seemed to gain a weight I’d hardly noticed in the past, as if marks of another, removed, maybe more harmonious time. If the figure of the flâneur is associated with a passionate connoisseur of the bustle of urban life, the relative emptiness of Berkeley CA became a space of which I was keenly aware not because of the fabric of the city or alienation of capitalism, but the relation that I had to the sidewalks beneath my feet, and the encoding of telegraphic scripts they offered in the worn cement of another time of over a century ago. The strikes from 1918, 1906 and 1904 suggested a town only emerging from the conventions of real estate and private residences that now fill the streets of Berkeley today, as signs of an early form of settlement–or early real estate market that seemed to boom already before the San Francisco great earthquake of 1906, that terrifying horizontal displacement of the San Andreas fault that in less than a minute sent powerful rumbles from its offshore epicenter across the region and, destroying many houses and buildings to displace many across the bay.

These old stamps, as I ventured outdoors on long walks, offered contact less with the bustle of inhabited spaces, than their increasingly resonant echoes of pasts, but were almost something suddenly worth study. The stamps stood for a new sort of contact with urban space, that almost made me stop in puzzlement and take me out of the present-day. This seemed a sort of urban archeology of the everyday, encountering what might be a sort of architecture at my feet. On these walks, perhaps, I was maybe channeling the first self-proclaimed botanist of the pavement, Walter Benjamin, trying to formulate an urban critique by situating myself in new surroundings. The stamps seemed, for a time, something like talismans able to redirect cynicism of the moment.

The stamps set before local single family residences before the wars of the twentieth century were signs of a booming real estate market, but an industrialization of pedestrian life. While I’d never thought much about Berkeley or California in concrete terms before the 1920s, the stamps of pre-war Berkeley traced a settlement of urban space with a tactile nature–and the slip of that inverted “N” in stamps of the Oakland Paving Co, an accident of setting letters, welcome as an ability to touch the past, as if newly conscious of a more contingent present I seemed to have lost clear compass bearings on. Maybe in response to unneeded panic, I welcomed the remapping of a community in these old stamps as if they were reassuring names, as if in contact with the traces that these engineers of the sidewalks left on the ground below my feet, whose often elegant geometric escutcheons seemed like clues of local housing patterns and portals to another time.

The sudden sense of connoisseurship of the pressed pavement seemed an earlier letterpress era of print, a sense of legibility far easier to decode than viral transmission, mutation, and decoding genomes, but also a removal from the present. As I was starting to find my footing to walk in these almost abandoned streets, the dissociative rhythm of finding markers from an earlier time seemed a way to escape the present and its anxieties. I started to find a sense of a lost order that seemed to be traced on the pavement as I walked the empty sidewalks in the late afternoon, streets abandoned, names started to seem lists, or even doubled as a set of gravestones, as if infected by the growing sense of mortality as I felt its weirdly imposing effects.

I spend a huge amount of time, walking, as if emptying my mind, facing the stoic silence of stamps set into those stony surfaces, as welcome recognizable touchstones. Perhaps they offered antiquarian busywork, as if cataloguing signs of time past kept at bay the uncomfortable sense of pausing any natural rhythm of the day, or a reprieve from anxieties that hinted at an “oceanic” feeling of Sigmund Freud cast as a sense of oneness with the world. The improbable survival of such stamps offered a reminder of past, if also of loss, whose very fragility was testified by being obsured or erased by foot traffic–as an early stamp on Benevenue Ave., near by local community independent coffee shop that the main online source on these curious stamps omits–the sidewalk before the 1922 building was paved by an Italian-American immigrant duo of pavers based in Oakland, whose incursions into Berkeley date from 1922.

The talismanic names seemed able to ward off the cynicism of the moment. At the time, with little script , and an illusory sense of the stoppage of time dominant in my conscious, the sidewalk markers of old and long-dead pavers seemed to speak to me. Amidst the tally of a surrogate for psychic stability of sorts amidst increased step-counts and improvised destinations of an oddly existential air, I was looking for a path for stability and seeking distance on the pandemic in the century-old stamps set in the concrete pavement like early claims of private property. The puzzle of this piecemeal paving of sidewalks, driveways, and pathways before houses seemed itself an imrprovised formation of a “city” as a real estate gambit, evident in the early maps–this from 1906–of the area on the Berkeley-Oakland border where I live.

A Map of Oakland, Alameda and Berkeley, 1906, detail (Berkeley-Oakland Border as Thick Dashed Line)

The map that was in essence the streetplan for the area I was renavigating by pavers’ marks was the included in thick green outlining the ‘Fire District’ in San Francisco, the proximate disaster all but absent from the Oakland and Berkeley maps, on its recto, a destroyed zone of the city where for several days after April 18, 1906, a fires had raged that killed 3,000 and displaced many more: the disaster was not included or in evidence int he map, that seemed hardly to register the shock or aftershock of the minds of those who used it. But as thirty fires consumed over 490 city blocks, and 25,000 buildings, the disaster brought the overflow or migration to the East Bay: arcs drawn over the map registered the distance from the Main Line of the Southern & Pacific railroad and thick green lines the Key Company bus lines, that linked the East Bay and San Jose, in the map of 1906, as if mapping the distance from San Francisco, for those who had to leave the city.

If echoing the concentric zone maps designed by the urban sociologist Ernest Burgess to map the sociological organization of criminality, race, and other social groups in the young metropolis of Chicago, mapping “dubious dancehalls,” the composition of families, the sharing of domestic space with lodgers or relatives, or diagnosed manic-depressives to better understand the “subcommunities” of urban space. The “zone maps” that plotted Burgess’ social observation were rather–familiar from the Bay Area?–be used to reflect or map “commute time.”

Concentric Circles in Candrian Map, 1906-2

Perhaps there is not evidence in the pavers of the “hidden wars of the American West” Solnit so powerfully traced–if they were effectively reclaiming once indigenous land as private property, that battle had been effectively lost. But the immigrants who paved these pathways in a piecemeal fashion with realtors suggested the mosaic of the East Bay’s past. The wars of private property and single-family housing were fought on its front lines in Berkeley, as it turns out, and the conventions and contracts among private real estate owners and real estate schemes that were the seeds of Berkeley–and, for that matter, of the University of California’s premier campus, relocated with plans of William Hillegass and Franics Kittredge Shattuck to sell a portion of land to the University of California. (Shattuck and Hillegass had partnered in a livery stable in what is downtown Oakland, by the current Jack London Square, and the streets to which they lent their names in Berkeley defined parameters for the old College of California.). And those distance arcs emanating out to Berkeley from downtown Oakland illustrate the demand for real estate that led a flurry of sidewalks to be built, transforming the landscape in years after the 1906 earthquake.

The sidewalks preserved traces of these stamps, of less storied men, isolated fragments not worn by footsteps of pedestrians or lost to time. Their survival seemed to provide way stations that were guides to a lost trail of the built residences in the East Bay by resourceful men, suddenly invested with a weird heroism I’d been loath to attribute as crafting the stability of a past geography of early twentieth urbanization and public space, even as our social fabric had tragically frayed. These unknown men who left definite traces in the sidewalk stamps of what now seems modesty–Blake & Bilger Company, founders of the Oakland Paving Co.; J. Catucci, Gen[eral] Con[tractor]; Spring Construction Co.; C. Burnham–seemed like heroes of the forging of an earlier city, even if it was more of an extra-urban enclave.

Unlike the screaming outside and overbold pronouncements, the reticence of the geometric sigla pressed into concrete were the safe spaces in a pandemic filled with disinformation and dread. As each inch of the public sphere was filled with cautions or false security, the hidden trail was a weird way of giving some purpose to long walks in the early morning and late afternoon. If critique was a way of distancing oneself from online panic, the strikes provided a sense of grounding

The forgotten names on sidewalks of these old engineers of the city not only hearkened a sense of modernity, not yet obscured by the shuffle of feet and still peeking over a century of pedestrian traffic, time-stamped with barely legible dates like 1908, 1904, 1906, or 1912, but exultant markers of the achievement of modernity: they had paved the ancestral Ohlone lands for private residence, and the boosterish hiving off of private residences, just before but no doubt stimulated by the great quake across the bay–when the twenty foot movement of one tectonic plate sent so many suddenly homeless fleeing San Francisco seeking temporary security in the old East Bay, increasingly consumed by real estate markets of time past. I was, of. course, retreating from the datascreens of mortality and hospitalization, of COVID infections and of excess mortality, finding a more tactile antiquarianism in the insignia and escutcheons of an earlier era that were basically old advertisements for the benefits of solid, level paving, whose date maybe was primarily an indicator of how long they would endured. And it was that endurance that appealed to me in an age of suddenly and unexpectedly heightened awareness of all of our contingency.

The stamps of pavers was in a way a placement of “Berkeley” on the map, 1899-1918. If many, seeking orientation to what was unfolding, exasperated at the overflow of global maps of pandemic spread that were intellectually impossible to balance with one’s fears for those loved, many looked to the classics–Defoe’s Journal of a Plague Year, Manzoni’s The Betrothed, or Camus’ The Plague. (A copy of the latter arrived for my daughter by post, as if to keep her up with the latest existential quandaries, although it remained unread.) The texts framed in the ground, set like time capsules of a past century, seemed to provide a weirdly comforting grounding–if not orientation–as if they became the deep history of place against our quandary. Indeed, the paths that I seemed to be tracing or finding of the paving of sidewalks outside of single-family homes seemed to be a path-finding, of sorts, to the landscape of private property by which the East Bay landscape is now predominantly defined. What more apt way to witness the pandemic unfold?

What could one read effectively, anyways? As we isolated in place, I tended came to consult the inscriptions stamped on the pavement by contractors, as if they were the neighborhood elders. For in the moments of small excursions by foot, and in walking increasingly only on foot, despite diminished pedestrian encounters, I looked for bearings from epidemiological disorientation in the sense of deep time that the sidewalk stamps of my Berkeley neighborhood offered, as if to gain from the a sort of psychic stability. The discovery one day of a 1912 stamp set twice in the concrete before a house that did not look nearly that old began a search to escape to the traces of a past world on the Berkeley-Oakland border, but continued as the sidewalk stamps of earlier generations became a solitary hunt for. a lost community, or a substitute for the sidewalk sociability that I treasured as neighborhood life.

Walking more widely with less in mind than other periods, I began to read these imprints as transactional sites of memories, on the pavement I daily walked up to where Claremont Avenue bound from 1905 a subdivision promising residents “sunshine and hills” in single family residences. The close cousin of the imprint framed a trans-dimensional memory of place, history, and housing that seemed to pop into relief on relatively empty Oakland streets. And when I found, nearby, a set of stamps from 1904 from the same company, the sense of imagining the pouring of the streets I walked with regularity, before and after dinner, as a solace form the anxiety of deep disruptions of urban contexts. In a weirdly isolated search for social reparations, I seemed to find a sense of solace in imagining their historical context: tracing the dates and legibility of these signs of the security of a community that was frayed.

I came to think of the imprints pavers had stamped on the ground as a surviving unnoticed network, a reassuring social network I could help rise from the dead to reconstruct traces of an imagined past village community, when concrete was mined from Oakland, Albany, and Emeryville quarries. On walks, I became the imagined intermediary of a past I had not noticed, communing silently with men like Blake & Bilger, Frank Salamid, the Schnoor Bros. (or their progenitor, Paul, who showed up as early as 1908) and even the Oakland Pavement Co. as I traced the local genealogies on what must have been the newly modern form of paved sidewalks that were a feature of what had emerged soon after the San Francisco Earthquake of 1906 as a site of single family residences, and a refuge, in those days, from fears of tremors. The comforting company of these inscriptions that from an earlier era, predating World War I or World War II, and the catastrophes of the twentieth century, seemed a perfectly available form of escapism, at first, to navigate the world that was until recently uncomfortably crowded by the false fraternity of Tech. Bros poaching local real estate–and raising its prices–from Silicon Valley.

Amidst the challenges faced by the nation, amidst the rising specter of increasingly apparent deep-set inequalities, disparities, and deficits of public health, I fancied to be able to uncover an old urban infrastructure encoded in the century-old names stamped into the ground, pavers’ stamps of a tactile legibility I’d long ignored, but seemed removed from the dizzying distance of records of mortality, hospitalization, and viral spread that seemed almost impossible to comprehend or assess, and both reassuringly material–and present. The imprints on local sidewalks gained an increased interface that I’d rarely felt, even after living in North Oakland and Berkeley for far over twenty-five years, as the names of long passed contractors, cement pavers, and construction firms appeared as offering evidence of a sort of urban infrastructure, revealing a lot about place and the longstanding status of the single-family residences in my neighborhood; reading the scattering of cement inscriptions excavating a sense of place by sidewalk engineers, tracing a deep archeology of place that was shaped by real estate markets, social inequalities, and a half-way house of urbanization in the early days of the expansion of the East Bay to which I retreated readily, as if reading signs from what seemed the first pavers of the ground.

The earliest “strikes” dated were from over a century and a quarter ago–1899 or 1905, and even a 1901 and 1904–the majority charted the expansion of the city, and the shifting cast of characters who framed driveways, pavement, and on the city streets, offering a distraction from that peeled me from confusion or fears of contraction of the virus. Moving up the street on which I live, confined to the 2000’s blocks, I started reading the ground as a remove from the global, even imagining a lost village community of the time when mining pavement came from local quarries, engineers had names, that fictionally rooted me in ways that seemed welcome. If in Graduate School as an early modern historian, we’d joked that we were spending summers on researching the unexplored archives of early modern Oakland and its relation to the Mediterranean economy, riffing on the great French historian Fernand Braudel’s insistence to expand n the perspectives on historical time, space, and even periodization or events, it seemed that traces of early modern Oakland lay in the cracked pavement at my feet, a neglected history of neglected records as deep as they were confine to the superficial, at my feet, tracing mobility patterns in Oakland and Berkeley in a profound way that one could tease out to read the city in concrete, even as the raging pandemic traversed borders and challenged medical science.

As I walked to coffee and manufactured errands, taking stock of the empty streets, the individual imprints left by pavers from between the 1906 earthquake and the Great War seemed a form of public memory. Perhaps there was a greater sensitivity to them to champion as we were debating memory as a nation, if at a far less local scale. The stamps set in concrete sidewalks near by house staked a claim for permanence, before the Great War, and before the ‘Spanish’ Flu raged, trumpeting with an optimism the newly constructed lands of a built East Bay.

The sidewalks of sold lots of what were once indigenous lands staked a claim as a new part of the city, expanded be the entry of folks from the city across the bay, but also an entitlement of lots for new housing–literally, titles–that the real estate corporations and construction firms built, a sense of a signature on the ground that was asserting a new form of mapping residential neighborhoods. And taking these imprints, as the 1911 one I came across near my house, invitations to think about time, and about the new contours of place, I came to think of them as a secret sort of map, very much imbued with the materiality of a receded past that still informed the neighborhoods, the troweling of sidewalk lain over a century ago suddenly seeming both an optimistic assertion of permanence and a melancholy record of the past, when the landscape was redefined by concrete resurfacing. But these were heralds of the single-family residence, testimony to early work paving the sidewalks or driveways of individual lots, distant echoes of that gospel of propertied American individualism, that seems to have hurt us so in dealing with the pandemic as a problem of public health, or occasion to invest in public health policy.

There is something similar about these prints that recalls the early wall-building, before the establishment of the law, that Romulus had staked around Rome’s limits that separated the civilization of the city from the surrounding barbarism, as pathways and roads that, as Vico had it, into the institutions of human society by the building of roads and walls around fields.

The legibility that these sidewalks assumed as part of a historical record, long overlooked, seemed almost a source of security, and a form of memorialization, far more than antiquarian curiosity. Perhaps the prsence of fewer pedestrians altered human geography to remind me of the delicate construction of our sense of place, the flat surface of the pavement provided a weird surrogate for the absence of familiar faces on the street. In an age when we were reading webmaps, synthesizing global data of infection rates across countries and states, the local lens of the pavement had a concrete sense of specificity that those webmaps lacked.

–that even if undated seem far older evidence of the Oakland Paving Co., lugging cement quarried from the old Bilger Quarry in Oakland’s Pleasant Valley that from 1910 offered, as “The Oakland Paving Co.” met the need for metamorphosed sandstone for macadam and concrete to pave Berkeley’s sidewalks, in the years after the San Francisco Earthquake, meeting the demand for paved streets in the East Bay over a century ago. My historical training seemed to click into gear, shifting from the webmaps of the pandemic’s spread to the poetics of the paving of the sidewalks I had long pounded since arriving in the East Bay almost thirty years ago, without giving much notice to reading what was lying under my feet, as the geography of the repaving of the city popped into unexpected historical relief as the mute stones started to speak as I looked down at them.

This rediscovering of the local in the midst of the pandemic was a remapping of place, as we were trying to process global maps modeling the spread of infections and, soon, mortality, that almost resembled a flight path map without the vectors of transmission that we were asked to reconstruct. For in contrast to the smooth sections of finely grained grey paving, the mixed macadam of earlier eras surprisingly offered a site of dialogue and historical orientation as material culture, a point of dialogue while moving far less to meditate about how we mapped space and place. As the numbers of flights contracted, and we grew less global, we measured ourselves in relation to a global pandemic that we seemed only oddly able to see in local terms. But perhaps this was, yet again, only another iteration of the fate of globalization.

The global diminution of air traffic occurred as we were tracking the spread of a virus across national borders, moving in global webs of claustrophobic mobility and transportation across borders with a heightened smoothness that was forging transnational linkages of the most deadly sort, eroding the concept or use of national sovereignty over public health, the lines of these early pavers of sidewalks offered a local text whose superficiality seemed oddly comforting to trace and almost profound, meta-geographic markers of an earlier era before gridded space was widely accessible–as if it offered another way of negotiating with the dead. As global traffic slowed, and we sheltered in place, and afternoon or morning somewhat aimless walks became a form of meditation, the sidewalks became a weirdly present interlocutor.

As much as fiction provided a respite from the specter of infection that became existential as it approached our space, blurring boundaries and destabilizing ourselves left us searching for a playbook, pavement provided a needed form of orientation, the work calendar interrupted. The storied names of the pavers of the cement sidewalks on the Berkeley-Oakland bore offered a parallel text to one of loss, as the names of contractors and pavers gained presence as a story of urbanization, and urban inequities, reactivated by the landscapes of loss.

The old sidewalk stamps left by pavers’ that dotted the border between these Bayside cities of a patriarch of one of the family of pavers whose work fed the city’s increased population after the 1906 Earthquake killed over 3,000 and destroyed 28,000 buildings–leaving some 25,000 homeless, growing the East Bay residential centers seemed in the pandemic to gain a commemorative cast as sites of mourning.

On or about April 18, 1906, the pavement set by men who owned quarries in different parts of the East Bay–Oakland; Rockridge; Berkeley; El Cerrito–set a new infrastructure for residential housing, whose echoes we still felt on the edges of a real estate market of extreme gentrification. The evidence of earlier construction firms who seized once indigenous lands was less evident as a pedestrian while sheltering in place in Berkeley, CA, than the materiality of these signs perhaps monitory and perhaps memorializing, but literally concrete. The crisp lettering left by the Spring Construction Co. on Regent Street and Benvenue Street on Berkeley’s southern border was spied by Lincoln Cushing on a schoolyard in Albany, without a date, and far crisper capitols.

In a season of increasing questions of commemoration, memorialization, and remembrance that were rising across the country, the sense of a hidden topography able to be traced by rose to the sidewalk’s surface. Once seemingly stolid “pavement strikes” set on sidewalks of north Oakland of the post-quake era seemed almost ephemeral, whose status as signs of the old expansion of an residential neighborhood might have seemed monumental–Look upon my works, Ye Mighty, and despair!–seemed suddenly transient signs, an old geography peaking up at intervals amidst transforming real estate markets that have carved up the East Bay over the last twenty years. The post-quake signatures left by pavers from College Avenue–“Paul Schnoor, 1909“–to off Ashby–“Oakland Pavement Co, 1904,” with an inverted “N”–or off Telegraph Avenue–“Burnham Co., 1908“–plotted the booming if not forgotten benchmarks of a past, revealed the engagement of the engineers of new neighborhoods by agents who elevated themselves during the Depression by elevating themselves 1920’s to 1940’s as “Masters of Concrete” as if engineers of place and built space on the blurred border between Oakland and Berkeley.

6459 Benvenue Avenue, Oakland CA

Was I walking in an old urban topography to escape the present, or looking to these benchmarks with a knowing sense of the lack of stability that they offered, peaking through a landscape of high gentrification as oddly uncomfortable echoes of a distant past?

Walking around my neighborhood with increasing frequency, I began to think of myself as not wandering to coffee shops and errands, but, more purposefully, as we all needed to embrace a sense of purse, doing research in the concrete archives of North Oakland sidewalks, searching for material signs of the past. When Walter Benjamin famously described the flâneur not only as a stroller, but as engaged critic of modernity whose act of navigating urban space had its own intentionality, in Franz Hessel’s Sapzieren in Berlin, moving in open urban spaces as an act of resistance, not bound by planning grids, but to appreciate “its charming disorder, branches crackling underfoot, the rustling of leaves on neglected narrow paths.” If Benjamin saw urban walking as “botanizing the pavement;’ the cracked concrete names traced a natural history of Oakland. amidst scattered leaves that told a hidden history.

6140 Canning St., Oakland CA

Before the moniker “Master 4 Concrete” adorned pavers’ strikes in the 1920, these signatures seemed deeply fragile, yet a remapping of streets I fancied to watch from a distance. Like rare surviving benchmarks of a past Bay Area built on Ohlone land, these century0old names evidence of the reshaping of the settlement of the Bay for Anglo residences, that survived by chance, seemed oddly transient sites. I almost mapped them not as signs of pride taken in careful work, but as something like the mass graves under the sidewalks, mortality in the air, and signs of a sense of transience, as much as permanence, as they gained something of almost Ozymandian resonance asking me to look upon the manufacture of such sidewalks as I seeemed to, in fact, despair, a grim sort of flâneuring indeed.

These were the architects of a new sense of modern built space, after all, that paralleled the growth of the first writers on public walking–the art of the flâneur won currency, after Baudelaire as one who “walks the city to experience it,” in 1863, even if I was walking to experience its absence and the pastness of its past. The encounter of a name of the once venerable patriarch of a family of pavers, forename slightly cut short by the repaving of part of College Avenue, was akin to evidence of the dense artificial stone paving of 1908, on the Oakland-Berkeley border, two years after the Great Earthquake sent tent-camps of refugees to the East Bay, as one of the first forms of urban infrastructure of crushed stone–paved sidewalks!–laid quarried sandstone, basalt, jasper, gravel, and schist over macadam to create a walkable urban space, sometimes sandwiched within new cement blocks.

6048 College Avenue, Oakland CA

I walked to remember the city, and to know it, to distance our destabilizing sense of not knowing that we find comfort in putting to work these humanist texts to gauge their relations of illness in a epidemic or pandemic, to reactivate their readings of texts that have lain dormant in whatever ways they could? The flattening sense of the pandemic oddly echoed the trumpeting of globalists in the benefits of a flat world, as the virus seemed to move across global cruises, in airplanes and airports, in conference centers, restaurants, trading routes, and motorcycle rallies, unmooring our own sense of controlling space or situating ourselves in a “safe” space. And if I found MontrĂ©al’s public health outfits warned me against such lounging and pedestrian familiarity on a visit to the city–no flâneuring, please!–the attempt to gain purchase on the city with some distance in Oakland seemed second-nature.

Gare Central, Montreal, public notice

The attempt to gain purchase on space, or on the global space of disease, led me to look at the flatness of space that I negotiated on walks, examining the pavement of Berkeley CA to find orientation in the markers on the pavement, often left as stamps in the concrete by the sidewalk pavers whose lives and urban infrastructure I payed more attention to as a reminder of the incomprehensible loss of life. The stability of these old paving marks suggested a sense of the often overlooked–if not unexamined–traces of urban infrastructure, that expanded from the time that horse-drawn wagons carried gravel from quarries as far as Alameda or El Cerrito to motorized fleets carrying over 300,000 cubic yards of gravel, macadam, and rock around the Bay Area.

These often broken sidewalks seemed grim evidence of the breakdown of our public health framework. While no one much cites Tom Friedman these days, “disease” was one of the few ways in which the world appeared unflat for the journalist who became a booster of globalization: the “un-flat” nature of India and China was, Friedman feared, most apparent in risks of disease, but where he argued the internet offered the closest to salvation of an impending flattening; yet the rise of this new emergent disease arose on account of accelerated modernization of China where the encroaching of urban expansion and growth into the hinterland from where this new pathogen seem to have hailed, per the World Health Organization. And we looked at the maps of infection’s spread from this point in the map to find that the world was indeed rather flat, in the unpredictable pathways it frictionlessly spread among populations by trains, planes, and ships without any barriers among developed countries, in the shock that we suddenly perceived that regarding this pathogen, the world was hardly “un-flat” at all, and the flattening effects of technologies of sequencing of the virus were less pronounced than how the virus moved along or disrupted the “large, complex, global supply chains extending across oceans” that for Friedman were such an unmitigated good that the “unflat” experience of the world was remedied by Bill Gates.

We are, or were, trying to process a topography of death rates but fell back looking for tools to process the effects of the arrival “emergent infectious diseases” as we entertained their origins in the degradation of ecosystems and encroachment of formerly protective boundaries between humans and animals that have increased the risks of pandemic disease as zoonotic diseases have entered densely inhabited cities as if marauding dogs. The incommensurability of all earlier literature with the global pandemic is nicely suggested in Phase Six, a pandemic novel Jim Shepherd was writing as the COVID-19 outbreak occurred in Wuhan, whose ominous title was “designating for anyone who might have missed it by this point by this point that a global pandemic was officially underway.” The weird rapidity of the transport of that RNA strand that so readily replicated in human bodies by zoonotic transmission traced and mapped from the global wildlife trade. The dry imprints of once wet cement stamped as evidence of an earlier sense of place, and somehow seemed to speak to the tangibility of an earlier era, which I read them as if from the other side of a temporal divide.

In the piercing sunlight of several days when I was most likely to walk, the intriguing nature of the stamps took me to a present while the virus was taking us all over the world. Shepherd was in the course of telling a global story in compelling local detail as COVID-19 broke, but after Global Public Health reported 90% of epidemiologists foresaw the emergence of a pathogen, not yet identified, would lead to over 150 million deaths. The toll was one-and-a-half to three times as great the global influenza pandemic of 1918-20. Shepherd may literalize ’emergent diseases’ of unknown transmission vectors and incubation for the pathogen that emerged from the frozen tundra that was being mined for rare metals, one of the array of cataclysms of global melting with which we have not yet come to terms, as CDC epidemiologists valiantly struggle to map in a chilling novel pointed up fears of a pandemic suddenly unfolding in real time. It was as if the world had caught up with the fictive world he was writing, and as I was caught up with pre-pandemic fiction that imagined the now-arrived present, an eery Moebius strip was complete.

We returned to the influenza pandemic misidentified as the “Spanish” Flu, to seek bearings on the growth of an actual pandemic threat, feeling a vulnerability for which we lacked clear guidelines of response. The recurrence of the dates before the Spanish Flu arrived in San Fransisco that I crossed on some stretches of pavement alone seemed significant as they suggested an apparent lacuna in the marks left on Berkeley sidewalks and across North Oakland’s residential geography. As I stared at the pavement on nearly abandoned streets, scanning the asphalt for signs of understanding, I found the strikes of old contractors or pavers something like an interruption or a punctum, making me pause in my tracks. COVID was forcing us to come to terms with those we lost, in new ways, and as I took breaks for psychological balance, single names seemed like community remembrances of those forgotten in the last century. I had recently moved from one of the leafier areas of north Oakland to an area of far “oranger” hue, at least not of the kelly green canopy I’d been accustomed, and the marks left by pavers were perhaps more evident, as the streets were certainly less populated than they once were.

As the United States closed its borders in response to the global spread of COVID, and the virus spread across the globe, while we all studied global maps of virus vectors, variants, and mutations to try to track its spread, I walked in neighborhood streets with a combination of apprehension and a need to find solid ground, or tried to affirm the signs of the community where I lived. It was perhaps not by accident that the contractor Richard Schwartz identified the massive growth that the city experienced after the 1906 San Francisco earthquake, as refugees expanded the population of Berkeley and its paved streets by half in a month–growing from 26,000 residents to 38,000 overnight, as Berkeley and Oakland set up large refugee camps and tent cities in response to an unexpected influx of unhoused. As COVID-19 plunged many into poverty, increased gaps in wealth, and dispossessed many, and placed refugees in crisis, I searched the cracked sidewalks of my own city for signs of our relation to a global crisis.

Many then fleeing San Francisco arrived in settlements despite the absence of infrastructure–the largest number displaced arrived in vacant lots open on Adams Point, north of Lake Merritt, if not in the military camps that were set up in San Francisco, if not the “earthquake cottages” on wooden platforms, akin to the “tiny homes” in Oakland and Alameda for unhoused and at risk youth or now via AirBNB. In Berkeley, settlements were quickly established without galvanized steel to accommodate those suddenly unhoused, creating a landscape of refugees living in lots.

As we processed the pandemic, we were, predictably ever more addicted to comprehending global maps than narratives, as if finding increased justification for social media addiction in refreshing dashboards of hotspots, hoping for bearings on the infections, hospitalizations, and deaths might arrive. We seemed to be tabulating in our heads and reading from the newfound authority of our screens, internalizing geodata of uncertain authority, it was increasingly therapeutic to imagine the pleasure of discovering new geodata on neighborhood sidewalks, making alternative maps that seemed affirming in my mind. Movement curtailed to some extent, the antique pavers’ strikes on the sidewalks seemed akin to dated billboards above a ringroad, each dated name seemed a refreshingly concrete reminder of location and located-ness in the modern pavement set a century ago. As I walked in more confined places than usual around the streets that lay effectively as they did when the earthquake hit and the exodus of refugees to Berkeley occurred, seeking stable ground and hopeful of new residences–at a time when few streets seemed to yet exist or be paved above Claremont Avenue, and few lots were even sold.

Although the exact border between Oakland and Berkeley had changed, and many streets’ names by the Bay, my flâneur-like walks seemed to track or investigate the expansion of residential sidewalks as if to observe the expansion of modern life at a historical distance. I began to walk to navigate that shadow geography of the past, by old marks on the pavement, opening the archive of stamps left on the concrete sidewalks in order to date residential neighborhoods or look for early clues in paving, to sketch something like a metageography of the neighborhood to keep the present at bay.

As he developed and expanded Leaves of Grass at the turn of the last century, Walt Whitman about 1890 evoked the “populous pavement” in his Manhattan. The near abandoned pavements of the north Oakland residence where I seemed to spy a strike from as early as 1906 outside of my door, much abraded by footsteps and time, the triangular stamp of the venerable firm “Blake and Bilger” dated 1907–the year after the arrival of San Franciscan refugees in the East Bay–suddenly triggered a sense of deep time that hanging out with these pavement marks in solitary morning or late afternoon walks seemed therapeutic, a distance point as the name of the population of dead contractors removed me a different time, one where the Bilger Quarry by what is now Pleasant Valley from 1910 offered, as “The Oakland Paving Co.,” more than enough metamorphosed sandstone for macadam and concrete to pave Berkeley’s streets, if that pavement was clearly cracking over time. But the company that had sent its mark, complete with inverted N’s, from at least 1904 offered evidence of a

The pavers’ strikes popped from the pavement as discoveries of surviving snapshots of the residential expansion that escalated in the East Bay accelerated from around the time of the 1906 San Francisco Earthquake, in a search for residential stability and safety became, mutatis mutandis, sites of bearing and orientation on the pandemic’s escalating trends.

The areas of sidewalk paving that seem to start from around California Street in Berkeley seemed to offer teasing traces of the past history of the region, peaking out as an older archeology of place. But the divide that was clearest followed the divide of Shattuck Avenue, where I lived, a divide above which, as an elderly black homeowner who is my neighbor noted, lived not a demographic defined by race–but “racists.” Or was the divide Sacramento Avenue, the closest to the Bay that I saw marks of the veritable paver Paul Schnoor, whose signature on the pavement that dates from 1908 was “Schnoor & Son,” probably from before World War I and predating strikes of the growing business identified on other sidewalks as “Schnoor Bros.,” one of the most common Oakland strikes from 1918 through 1927.

The sharp racial divide of residential housing formed in the Bay Area was an earlier deep demographic fault line in Berkeley, where contractors stamped newly laid pavement in 1922, 1928, 1930, 1931, or even around the same time Benjamin elevated the street-walker to the level of a critic of the corrosive effects of modernity and capitalism in Paris, as much as a chronicler of the present that Baudelaire imagined, a witness to the divides that afflicted modern life, who walks the streets to register modern pains in street signs, crowds, facades, or fashions of dress. What, exactly, was not to criticize? The pavement that seemed so often to be cracked around these contractors’ early strikes stood as a sharp reminder of the fraying social fabric and aspirations undergirding this isolated residential community.

438-40 60th Street, near Howell

Of course, the streets were more empty in the pandemic, but the faces of past divides seemed to open like an archive set in concrete beneath my feet, peaking out at rare intervals. The strikes of pavers seemed akin to sites of geolocation to map the transformation of the Bay Area by the paving of residential roads, premonitions perhaps of the terrifying escalation of real estate prices that have led the population of unhoused to jump in Oakland by almost 50% from 2017 to 2019, the worst in the Bay Area, and encampments to grow in Berkeley by a full 13%.

The set of historical stamps I’d so often overlooked assumed a sense of a forgotten narrative central to the neighborhood’s shaping, long overlooked; they were perhaps snapshots of a history of effective segregation of residential community, that echoed the social stresses that emerged so clearly in the pandemic. I started to photograph them, as if to document this shadow geography of north Oakland, as much as looking into the past, to avoid the present; I was of course trying to map fixed surface or meaning in the ground as so much that unfolding in the maps of rates of infection with which we were all interfacing too often.

I passed dated markers which on increasingly empty streets seemed to regain their role of marking laid sidewalk as they were memorials–many reaching out as witnesses from the very time that Benjamin wrote of the transformation of urban space in Paris’ new social divides of urban spectatorship. Several, I noted, were from the first decade of the century, dates or final digits at times abraded with time or just left off–as if to suggest the rapid business of sidewalk paving contractors faced in Oakland from 1906, one of the earliest imprints I detected from the Blake & Bilger Company of Contractors, who would soon afterwards merged with the Oakland Paving Company, as if to declare the near-monopoly that the quarry then located on Pleasant Valley near 51st Street afforded adequate gravel to pave city streets.

Blake & Bilger Sidewalk Strike/Berkeley CA

The individual stretches of residential pavement in North Oakland and Berkeley, a consequence of the historical sales of residential units which contractors paved and signed with strikes to advertise their wares, gave sidewalks a board-game quality, the different years of whose laying seemed to jump out like snapshots of the past, suggesting a topography of settlement and residential units of the city years before the Earthquake of San Francisco of 1906 and its related fire encouraged settlement across the bay.

2936 Ellsworth St. Berkeley CA

If contractors’ strikes provided clues for the old residential neighborhood, ephemera, miraculously not rubbed out or repaved from gentrification, I smiled at the interruption of strikes of concrete contractors by a geomarker that seemed of the early days of mapping, when we were only beginning to internalize geolocations by our handheld phones. The paving of streets before World War I and the post-war pandemic of the Spanish Flu seemed eerily present in the pavement, staring back at me, as an image of the modernity of Oakland CA, on cracked old residential sidewalk of 60th Street, just above Telegraph,

440 60th Street, Oakland CA

that promised a “Home Stead” in the street, an early imprint left by an Italian-American immigrant paver, Frank Salamid, who legend has it left his career as a barber to pave Oakland’s residential streets after the 1906 Earthquake hit, creating a new market for urban homes. The name “Salamid” now recurs on so many North Oakland streets over a period of forty years, per geographer Andrew Aldren; the stamps of his brother, Angelo, who had emigrated in 1914, were among the first recognizable words my daughter used to recognize. Aldren, who richly charted the traces of contractors like Frank and Angelo Salamid on Oakland streets as “fossils in the city’s hardscape,” long before the Pandemic hit, the evolution of stamps Frank and Angelo’s contracting company left indeed date from 1909, soon after the quake forced the city’s expansion and sale of residential properties, but the snapshot near my preferred coffee shop offered a surprising view of another time, surviving in surprisingly crisply drawn cuts.

460 62nd Street, on Canning Ave., Oakland CA

When I cleared the leaves, it seemed to reveal it was set from 1909, and a nearby stamp around the corner suggested Frank Salamid had begun to ply his craft of concrete masonry by paving some of the sidewalks in the area where Angelo would continue at a later date, when he took over the company and its stamp became a squat diamond.

459-65 63rd Street, Oakland CA

The pandemic period produced a maddening claustrophobia over time, of trying to find diversions and also novelties in increasingly restricted familiar routes, as the sense of discovery was dulled in moving in a time we seemed to have lost direction, and collectively as much as individually demanded better bearings. Was there a meta-geographic meaning in these century old strikes, that might root meaning in a period we were inescapably addicted on our news feeds to daily data vis of infection rates, mortality rates, and hospitalizations, feeling the fraying of the social fabric suddenly intensify?

The pleasures of the truly metageographic conceit that was set on this part of Berkeley’s pavement seemed to interrupt or puncture the deep anxiety with which those other datamaps haunted my mind, as a single geographic point in space became the focus of my attention.

Antipodes Sandwich, Geodata on Prince Street at Halcyon Park

I had to laugh when I came across the “Antipodes Sandwich” geomarker planted in one spot of concrete–a precise spot of geographic coordinates on a urban cul de sac, if maybe not so precise as would warrant the fanciful proposal to place a piece of bread to make a sandwich.

Less able to concentrate to narratives, I took short interruptions of the problems of processing rising tallies. And if one pandemic drive was a compulsion to follow rates of infections, mortality, virus variants, and, now vaccination rates, to try to make order of world whose disorder seems more prominent than ever, in the forced calm of the cone of social distancing.

As much as reading narratives, we were all trying to put together stories, and the ephemeral markings I walked past on the way to get my morning coffee seemed more pregnant with meaning, the stylized signatures in antique letterings in contractors’s strikes on the modern pavement of the past seemed messages of another time.

Shnoor Bros, College Avenue, Oakland CA

As we scrutinized maps of the progress of the pandemic in the United States, trying to understand the pathways on which it travelled–the circulated air of hotels, airports, airplanes, or hospital wings, and the terrifyingly expanded topography of elder care across the world–the solid pavement offered a comforting concreteness, rooting familiarity in an apparently comforting sense of place.

The old marks not obliterated or scuffed off by the feet of pedestrians seemed reassuring, marks of the first residential sidewalks on the Oakland-Berkeley border constituted a “metageographical pavement” along an unclear differentiation of Berkeley and Oakland, ephemeral markings of an age of industrial production and expansion of the turn of the century, when the first residential sidewalks were lain for individual residences, in a sort of patchwork quilt of sidewalks that distinguish the region from most modern urban pedestrian space.

2031 Prince

Looking at these old signs of another era, I guiltily found inappropriate comfort in a “boring passion for minutia” by displacing attention from the pandemic in new ways. Sophie Atkinson re-read Robert Walser’s solitary pilgrimages with new appreciation in the pandemic–an attachment to walking without destinations–that found timely resonances of a comforting cosmopolitan nature during her extended walks in lockdown London. There was something of a sense of reclaiming the the known environment by these mobile practices of visiting the streets on which one had only recently walked, without any worry of infection or infection’s spread, as if one was steeling oneself by a reactivation of one’s investment in space. Walser, poetic prophet of post-modernity, she walked daily in search of an unexpected suddenly “significant phenomena, valuable to see and to feel,” by which “the lore of the country and the lore of nature are revealed.” As if on a similar sort of pilgrimage, searching for terms to discuss the comfort walks provided, observing and studying “every smallest thing,” an effacing self-surrender helped me to attend to local details of the material detritus of the overpaved world, as a way of remapping boundaries and proving his abilities to leave circumstances of confinement, was balanced with a drive for distancing current complaints–less with an eye to one’s destination, than a practice of re-orientation.

This was not contentment, but almost a policing of boundaries. There seemed something like a hidden network that was suggested by these old markers set in the wet concrete some generations ago–before the Spanish Flu, or before two World Wars, or our own Forever Wars, in the seemingly troweled imprint left four blocks East of my house, where I was first surprised to see evidence of the sidewalk paving that grew to accommodate Berkeley’s new residential neighborhoods where I currently lived, but whose once intentional bucolic remove suddenly seemed in fact quite distant indeed. Et in Arcadia Ego, indeed.

2308 Prince Street, Berkeley CA

Travel beyond the nearby counties effectively curtailed, I walked without any destination, for bearings on the situation. But I gained distance and escape, perversely, by looking, as if with renewed distance, at the strikes that local pavers left on the streets of Berkeley, circa 1909, casting myself in an unproductive flight of pandemic provoked anxiety and fancy at looking at what seemed archeological ruins of a present past. As the cracked common spaces in Oakland and the United States seemed increasingly apparent, I was trying not to aestheticize the broken pavement as ruins, but to find in them a basis for the social fragmentation of the pandemic, if not the frayed social fabric it revealed, as if to try, a bit naively, to map a sense of its deep divides. As the ground seemed to be cracking under our feet each day of the pandemic, the mute voices of these pavers of the past animated by imagining the marks they, long dead, had set in the ground as a distinct signature of modernity–J.E. Nelson, C.J. Lindgren, Esterly Construction Co, dating from at least 1904-12 in Berkeley and Oakland.

\Many of these names recur through stamps from the 1920s, unsurprisingly, as it began to seem almost a form of observance to notice how these long left signs their lives threaded through the Berkeley community that I now walked.

Was there a sense of familiarity of the pavement as a retreat or respite from the internet searches for information about the pandemic? The stamps following the 1906 Earthquake across the Bay framed the streets in another disaster, but seemed to offer a weirdly satisfying concrete relation to the past. The reveries of this solitary walker turned to an invisible sort of map, an alternate local map, as I sought some signs for needed security that lacked in the daily count of morality and hospitalization in the pavement that promised something like access to an elusive if somehow tangible past.

My favorite as i walked up Prince Street to my neighborhood coffee shop, a struggling site of collectivity, each morning, was the overeager Esterly family’s Construction Corp. seemed to so benefit from a booming business post-quake to not even keep up with the years, circa 1907-08, as the concrete sidewalk pavers filled increasing orders for paving residences in the developing residential areas on the South side–areas where the pavement had miraculously endured, with houses, as the residential communities intensified.

2420 Prince Street/Berkeley, CA

While this mark left by Esterly Consruction Co. is technically left undated, lacking a final digit, the strike and its concrete mix echoes and parallels a nearby stamp on Alcatraz Ave of 1907.

As if reading a one-to-one map that lay atop the neighborhood I lived, whose trades were apparent on the ground, I bore down on the micro-geography of the concrete sidewalks near my house, reading the names of pavers traced in the pavement as if ports of access to different ages. For the years that pavers stamped in strikes a century earlier, taking some sort of comfort in the clarity of the dates of their creation, mapping a sense of their coherence as benchmarks of an earlier era in the unstable ground beneath my feet, as if seeking a measure of clarity, a point of bearing on the area I’d been living in Berkeley CA but sought new purchase. The flat statements of these names and dates, dislodged of much context, and telegraphic in meaning, seemed to hint at a deep history of bordering, private property, and the establishment of a single-residence zoning in Berkeley I had never fully taken the time to appreciate–a truly “deep history” that haunted the area where I had comfortably sheltered in place, lying on the surface of the sidewalks where we had never thought to look, the detritus of Oakland’s modern space.

And at the same time as I started to haunt the corners of the internet, to construct an immigration narrative of my own family from Austro-Hungary and the Lower Carpathian region, during the sense of social isolation of the first pandemic year, as a sort of inversion or compensation for social isolation, the meditation on the isolated names pressed on the pavement of a century ago–around the first time that the boats carrying my family docked in New York and Montreal, from 1890s to the 1920s, the streets of Berkeley were paved. On morning and afternoon walks, as if fancifully tracing evidence of a deep history of the neighborhood as if in compensation for social distancing, digging deeper to an elusive past as I walked.

If the strikes of pavers were not reflective of the building of houses constructed in this largely residentially zoned area, paving city streets and sidewalks was an important movement of urban modernization, an early urban infrastructure, now invisible, along with the installation of sewer systems, electrical wiring, and gas pipes–the sort of urban infrastructure that was now being so deeply tried. While I often seemed to notice a stamp bearing of an even earlier year–1886!–revealed “1986” after clearing away pine needles; Mason McDuffie planned the first residential developments in Oakland in 1887, but the late 1890’s were rare to see on local pavements. If the driveways made by C.E. Orff or Jepsen in the 1920s and later, remaining some of the few unrepaved sidewalks in the area of Berkeley I had recently moved, an early planned residential neighborhood of the early twentieth century.

I’ve long considered paving as among the earliest of urban infrastructures. In the late nineteenth-century, the norm of dirt streets were replaced by downtown sidewalks made by pressed bituminous concrete, over rocks, surfaces of compound cement concrete–“art[ificial] concrete”–of sand, cement, and aggregate provided a modern form of building the city and urban neighborhood. Unlike in the East Coast where I grew up, the paving of sidewalk remained, as common in the western cities, provided by local property owners, and I could trace the urban plant of the city through the ostensibly ephemeral often anonymous marks left by pavers. I became fascinated with the uniquely dated texture they gave city streets, as if they offered a hidden architecture of urban space.

As if on an archeological dig, I traced signs in the sidewalk while walking absent-mindedly as evidence of the impact of the housing boom after the 1906 San Francisco earthquake on the micro-geography of the pavement, unpacking what seemed hidden history of the local, lying in plain sight underfoot, where they survived, marking the redesign of the residential community in the very years of the destruction of downtown San Francisco in the 1906 Earthquake and Great Fire that sent many across the bay in search of firmer land and residential property.

I discovered a virtual collective of old librarians, local historians, sidewalk aficionados with iPhones, with interest in filling cel phone memories with images of the evidence of the ground. In an age of increased atomization, the stone signatures seemed an imagined lost community of the area that were compiling the traces of trans-bay migration of a century ago, now a map that might be read as a dispersed set of portals to root oneself in a deeper sense of place and of time, rooted in the scare of the 1906 fire that sent many across the San Francisco Bay and nourished by the hope to segregate new communities, by the rise of covenants among residential communities, evident in post=1910 cities after the Great Migration, but already present in the late nineteenth century, but that flourished in the building of new gates, fences, and policies not limited to concrete, in which local builders like Mason McDuffie had specialized before segregated housing was outlawed, as groups like the Claremont Improvement Club adopted strict covenants that limited home ownership to those of “pure Caucasian blood,” reflecting the adoption of racial hierarchies in censuses from 1850, founding Claremont Park as a pastoral residential community below the Berkeley Hills by 1905, just before the earthquake, advertised in a color brochure complete with map, addressed to an imaginary “San Francisco businessman” as a site for calm repose across the bay, before the earthquake rattled San Francisco homeowners.

If The Oakland Paving Co.’s imprints of 1904 and 1912 near my house–earlier than Oakland sidewalks made from cement from the Upper Rockridge Quarry on Pleasant Valley and Broadway, used from 1910–suggest the value of paving on Berkeley’s expanding residential borders. The tasteful emblem of the inverted triangle on the sidewalks near the submerged Temescal Creek, undergrounded by culvert in north Oakland for elegant private residences off Claremont Ave. or to repave residential Berkeley streets for newly built neighborhoods, a transformation being a case of boundary drawing and social exclusion.

–or finding the same paver’s craft on Ellsworth Street in Berkeley, closer to my house,–

Some stamps lain by contractors, often specific to the day, seemed to set a basis for a residential neighborhood that seemed to be fraying in the pandemic, but that they seemed to remind me of, as ghosts of the un-remote past. If Lewis Carroll famously described a one-to-one map that had not ever been unfolded–“the grandest idea of all! We actually made a map of the country, on the scale of a mile to the mile!” that “has never been spread out” as farmers objected it would block out the sunlight, a map rolled out where it peaked through from the past; segregation of Berkeley’s neighborhoods began before 1906, promising areas of exclusively “residential character” removed from the “advancing tide” of “flats or shops,” in neighborhoods whose exclusively “residential character” was the result of racially restrictive clauses in property deeds and covenants on which developers like Mason McDuffie relied to boost their investment in neighborhoods’ exclusivity, hiring Frederick Law Olmstead to design the Claremont Hotel and Claremont Park community at a geographic remove from the city. The residential lifestyle allowed children to roam “out of doors! out of doors!” without night clubs or alcohol in prominent places, in East Bay enclaves exclusively for “Caucasian buyers”–not for “any person other than of the Caucasian race,” home ownership policies stipulated, with the result of mapping an exclusive residential neighborhood as early as 1905-1911 in the East Bay, or just before the Earthquake hit.

The shaping of that past neighborhood peaked up from the ground at select spots during the pandemic, revealing another world that rhymed in disturbing ways with inequalities today. If by 1907, West Berkeley was distinguished by streetlights, paved streets, telephones, and factories like soap and glassworks, and an industrial development fueled by the influx refugees from the city, invisible lines became increasingly important to define and defend. The new pavement added before World War I modernized the area of Berkeley and North Oakland for home owners in a new language of real estate and social class. As I seemed to be able to detect the names of a new generation of contractors of the post-quake years–Frank Salamid, J. O. Adler, and others–the rapidity of making a residential area, from below San Pablo Avenue up to College Avenue, seemed to gain focus, which I would not have detected with anything like that attention if time hadn’t paused, or seemed to pause, in pandemic days.

Jorge Luis Borges’s Del rigor en la ceincia embraced the conceit soon after World War II, describing, as American military engineers re-drafted national maps by geospatial coordinates that wrapped around the world, described a society that abandoned one-to-one map coexisting with the nation’s territory as it became “cumbersome”, as this large paper map was reduced to tattered fragments in some “western Deserts,” I imagined I found hints and clues that were central to the spatiality of South Berkeley’s Oakland border in the time-stamped impressions preserved in the pavement underfoot, as I embraced a sort of exploration of the surviving evidence as if excavated clues. The turn of the century provided an origins story for the residential community and its divides.

If roads to hell are paved with good intentions, the pavement strikes that stood out as marking space and time paved a space for single-family residences, sections of residential sidewalk paved for individual houses, bearing signatures of the forgotten artisans who converted what was once an empty property lot into a site of residence, leaving a sign of the quality of their work and the promise of future expansion of residences: these very pavers set the ground-plan of home-owners’ neighborhoods, the foundation of a shadow property association of the past. The sense of these strikes as something set by past lives–and defining past neighborhoods–was a microgeography dating from the early twentieth century, even before the Spanish Flu, but seemed to define as set a part a new area of paved sidewalks for single-family residences, that were newly settled after having been sold as, presumably, unpaved lots, probably at the edge of Berkeley, if now along the line of a north Oakland-Berkeley divide. The turn of the century definition of the comforts of home ownership across the Bay from San Francisco, defined as a preserve of private property, was a story that was inscribed in the pavement, if one I rarely took stock of or knew. The stenciled names below my feet revealed a topography of social differences and dividing lines. Was this a new form of memory, that I had been walking over and was suddenly, as much of the nation, trying to piece together?

The concrete sidewalk offered a tangible sense of the past, at the same time as a refreshingly tangible sense of time. At the same time as I looked up to notice a flower, tree, or park in new ways after weeks of deprivation of contact over the first year of the pandemic, as we continued to shelter in place, but my eyes turned to the ground in hopes for transcendence or finding some sort of different news, as if signs on the ground described possible sites of contact with an earlier world.

Was this only being middle aged? Or were there some deeper transactions I might have with the pavement, few other interlocutors being present on the city streets, as if in confirmation that we had entered a new era? As if walking with downcast eyes for unnoticed signs of old benchmarks and pavers’ names, I traced contracting and expanding routes as a pedestrian, looking downward to find meaning. And compelled by the keen awareness of temporality that seems to have affected me most at the start of the Pandemic, wondering what sort of era into which we were entering, and if we would ever leave it, the physical remove of these strikes, many from before the Spanish Flu which so many had seen or tried to see as a precedent for the diffusion of illness across the nation, and across the world, with high mortality rates, seemed to leave me scrambling for dates in hopes for drawing such seemingly futile senses of equivalence–or for reminders of a time before pandemics–as if rediscovering a new material relation to the past.

As newspapers came to be too exhausting to read and depressing in news, or the dashboards devised by tracking apps devised to convert databases of infections to the palettes of webmaps for ready legibility,–

–even as we had no clear sense of the mechanism or spread of contagion, or the arrival of the first cases of infection in California and the United States. If walks seemed to create a fragile measure of normalcy, tentatively, before electrifying news, the comfort of the tangibility of old traces on concrete seemed a form of security. If Walter Benjamin had famously looked back on the dangers of mechanical reproduction as a premonition of fascist media in the 1930s, after fleeing Nazi Germany to Paris, perhaps the craft-like manual nature of the individual imprints struck from frames and contractors individual signatures from bygone eras of Oakland and Berkeley’s past–strikes that continue to the present, and current dates–offered a reassuring micro geography of meaning. Seeking something far more fixed on which to focus than the rising rates of infection whose statistics seemed both the focus of much news reporting–if suspect as incomplete–I searched for fixed meaning about the local in these stamps, that seemed to fix a map of urbanization. And the old stamps in the neighborhood I lived from 1908 or 1912 began to trace a web of their own of urban paving, as I spied a 1901 stamp–suspiciously early?–off of Telegraph Avenue for the Oakland Paving Co., or followed the family histories contained in the stamp of Paul Schnoor’s early 1908 stamps to the expansion before the Great War of the new firm Schnoor and Son on a Rockridge driveway, cast in concrete, in 1912-13, and the prolific heirs of the Schnoor Bros. across much of Oakland from the 1920s to 1930s, a boom era of paving by all likelihood and surviving evidence on the sidewalks on which I started to daily walk.

This was a way of re-navigating my neighborhood, at a remove from the present, contemplating a deep history when we were in overdrive processing web-maps of the diffusion of the virus we were loath to call a pandemic, and as human-to-human transmission of the disease was confirmed and teh CDC warned us that “disruption to everyday life may be severe,” in mid-February, in what would seemed one of the understatements of the millennium. Was this a new wartime, as the global pandemic was declared by March, 2020, with its echoes of a global war? Critic Benjamin had of course fled Germany seeking signs of reorientation in the course of the flâneur in Paris, habituating himself with the modern sense of the streets as an exotic immersion in the senses. For me, the thin sense of contact that these stones offered in the time of social distancing were a far more muted surprise, meeting a search for sold testimonies in concrete form, as it were. It elevated wanderings as a new form of “botanizing the pavement” abandoned by most other passersby. Moving along empty streets without familiar faces, I read names of the architects of the sidewalk, taking comfort in and searched for names as if I could better acquaint myself with where we were.

I half-humorously fantasized that I was remapping space–that the odd exercise in antiquarianism on which I was thrown back, my daily work rhythm stopped, was a tiny effort to rectify inequality, a micro-reparation of the increased evidence of the social costs that the pandemic revealed.

How could such rates of infection be processed, especially as they were woefully incomplete? The epistemic unease at the security of mapping, or objectivity of these data maps that were queried, questioned, and re-examined, contrasted with the pressing urgency of trying to read the multiplying varieties of the novel virus itself, suggesting just how much we were still learning and needed to learn; the conceit of tallying the signs that seemed in full gave my apparently aimless walks a sense of purpose, as a form of reparation for a world out of whack, whose discrepancies of health-care, infection rates, and uneven levels of public trust seemed finally unmasked and on full view. Amidst the pandemic’s increasingly uncertain ground, I started to walk farther than usual from home, and walk with greater intensity of seeking an imagined goal, or justify my new status as something of a flâneur, dedicated to find the first pavers of main arteries like Telegraph Avenue and College Avenue in Berkeley CA from around 1908-9–the imprint of “Burnham,” or shortly after the Great Fire and Earthquake of 1906, met outmigration from San Francisco across the Bay, was registered by the surviving names of pavers, sharing the name of a contemporary city planner, Daniel Burnham, who worked in San Francisco and others, as the Spring Construction Co, who helped create local urban monuments as the Claremont Hotel.

Alcatraz and Telegraph, 1909

The names echoed the Berkeley-Oakland divide, from the 1905 paving strike of Spring Concrete Co., Berkeley, at the old craftsman house sitting at 3100 Benvenue Avenue., on the outside limit of the Berkeley border, to where the Berkeley-Oakland border emerges on College Avenue, at what is now the home of La Farine bakery, emblazoned by escutcheon strike of an industrious local family of pavers–the Schnoor Bros. who bridge three generations–dated 1924.

The doorway is non-descript, but the strike is evidence of sidewalk paving enshrined steep divides of income, today reflected in differences of infection rates among contiguous Bay Area cities, historically marked, long before their recent gentrification, by an open racial as well as a very steep economic divide. If sidewalk paving began by marketing “‘art’ stone”–artificial stone–by contractors as a modern replacement for brick or wooden boards, the lots that were sold for houses in residential areas shaped by laying wet concrete mix.

Were these Italian craftsmen keen to take the job as masons to craft the cement with necessary smoothness as they entered the city’s economy, or were they just arriving at the right time? Signing the paved sidewalk was not only the reflection of a craft–“Whenever a skilled person makes something using their hands, that’s craft,” reminds historian of craft Glenn Adamson–but a deep if superficial craft of memory. In staking out of regions for settlement along a clear Berkeley-Oakland divide, these strikes along the border set the terms for a terrain of marking out new residential areas of home ownership. Were these pavers not leaving tokens of their craft as contractors, in defining often Arts & Crafts residences in Berkeley CA, registering the imprint of their own handiwork, or just leaving their mark in the city?

Was one indeed able to map, as I imagined, the arrival of the very sidewalk of Spring Co. Concrete to the quarry John Hopkins Spring acquired on the former Berryman ranch in North Berkeley, site of Spring Construction Company, mined from conglomerate in what is now La Loma Park in North Berkeley, whose was quarried in North Berkeley 1904-9, and after areas near Codornices Park, Cerrito Canyon, that helped pave much of Thousand Oaks, and pavement bearing the Blake & Bilger triangular imprint to the Blake & Bilger quarry on Glen Echo Creek, near the Rockridge shopping center, owned by the Claremont Country Club, today, a site of mining metamorphosed sandstone, later run by the Oakland Paving Co.? Or was it from Blake’s El Cerrito quarry? A micro-geography of East Bay pavements seemed a hidden geography in itself waiting to be unpacked, of the quarrying and fragmenting of the hillsides of the East Bay–leading to an opening of quarries in Diamond Canyon, Hayward, prospecting in Livermore, as the search for sources of limestone, metamorphosed sandstone, quartz chert, and basalt grew in the early twentieth century with a greater demand for dressing the surfaces of sidewalks in locally sourced concrete. The Jepsen Bros. had owned quarries from 1912 to pave driveways and sidewalks that extended from Albany to North Oakland and beyond.

On often directionless walks seeking peacefulness, I looked with unaccustomed intensity at uninhabited streets for a sense of grounding, if not re-assessment, if the search may well have begun as my eyes looked downward as if by default. Walks without a destination led me to seek a perspective in an imagined sort of convalescence–a respite from oppressive data visualizations that were hardly a means to come to terms with the collective obituaries framed in the unfamiliar concept of “cumulative” deaths. I was struck by the somewhat random dates on the sidewalk in my Berkeley neighborhood, where “1911” arrested my eye–before the Spanish Flu pandemic!–or 1909, 1930, or 1936 pavers left inscribed nearby. If as a flâneur of the pandemic, finding and collecting the names of pavers seemed almost a search for transcendence by composing an alternate necrology of the neighborhood, as if a form of dealing with death, as the estimated deaths inexorably rose–even if they were all undercounts. The surety of walking offered an alternate form of tallying, as names of pavers became memorializations of individuals, akin to an imagined meeting, as if gathering information for an imagined alternative report; my income low, and indeed dubious, there seemed to be some ready temporary comfort in the small enchantments of the sidewalk to balanced with the global tragedy with perhaps few counterparts, if we often invoked the Influenza Pandemic of 1917-18.

The traces of grading the porous pavement were as visible as a laying of concrete that was smoothed out a century ago; just three to four hundred paces eastward, across Telegraph Avenue, the earlier strike peaked out of pavement cracking with more evident signs of time, where the paver seems to have left off a final digit, situating letters or plugs in a grid of sorts to arrange a company logo, that seemed a partner record of the material past.

I was bearing down on the local with a similar intensity on often aimless walks, as if searching for evidence or bearings. For turning to the local detail as a site of something like transcendence became a way of distancing a global disaster, or holding it at bay–and a profession of tracking a local topography of mortality as well. If Walser’s walking led to the melancholic realization that “I was a poor prisoner between heaven and earth, and that all men were miserably imprisoned in this way,” after his flights of fancy, the dates and names on the ground provided some sort of grounding that I needed to process mortality rates and the shifting maps of infection rates.

For all the rapid creation of charts of mortality rates that were painstaking crafted by epidemiologists and journalists in line charts that projected different possible counts, our expectations for certain data were frustrated as if looking into the abyss of mortality: the very fact that only a bit more than half of global deaths are registered–six in ten, the ballpark figure of the World Health Organization tells us, if 98% in Europe and 91% in America; the death toll of the novel coronavirus in Wuhan is guesstimated to be up to ten times as great as the reported 4,848 in the capital of the Hubei province, or as much as half a million, if reported global deaths pushed beyond four point two million, dizzying numbers if incomplete.

Financial Times, confirmed COVID-19 morality rates in UK and USA, March 2020-March 2021

The complexity of crafting a simple line graph of confirmed deaths and those due to complications of COVID-19 had us contemplating line graphs as specters of human mortality, whose complicated crafting don’t conceal so much as reveal the limits of certainty, and made me search not for global but grounds for transcendence underfoot. And in the days of social distancing, on walks that seemed perhaps aimless, but tried to find a sense of balance before the rising curves, following traces of the past set in the pavement seemed a sort of escape from the rising numbers, if not a destination. Daily walking was a rediscovery, as the trips from the house where I lived became less important for their points of arrival, pressing against the boundaries of the present condition, less in flight from something, than a type of convalescence from watching disparate rates of mortality and hospitalization rise, as my attention attended to something else.

If figures of infections, hospitalization, and mortality death haunted the air, solitary walking became a response to a restlessness–in the morning or late afternoon–and I was readily accepting the sense of the walks as haunted, or with added melancholy, in ways that seemed states of distraction and something of a befriending of loneliness, if not what past as sociability. Walking, for Walser, offered peacefulness as a way of seeking out being arrested by coming across the individual name, and the odd specificity of the date at which the pavement was lain, smoothed and left to set. Walter Benjamin felt that the walks the author devotedly took must be understood as with a spirit of discovery as a form of convalescence, “newly sensitized to the outside world,” there was perhaps a search for collective convalescence in the undue attentiveness birdsong, flowers, pavers’ names, as if struggling to combat or imagine a future remove from an overwhelming melancholia. In history graduate school, a friend and I had listened to slightly more senior students describe summer research plans of visiting archives with lightly veiled satisfaction, and imagined our intent to exploit the unexamined archives of early modern Oakland, where we lived, echoing how the French historian of the Mediterranean, Fernand Braudel, had described Istanbul’s unstudied archival treasures of Mediterranean trade, in his own search to gain a new perspective on deep time of a longue durĂ©e that seemed more than ever sadly out of reach.

It almost seems, in retrospect, as if I was discovering the existence of that very archive of lost communities inscribed in the pavement strikes–bearing dates from the 1920s and 1930s, at times a decade after the turn of the century–a material archive of early modern artisans or craftsmen who were technologists of the community that defined the old edges of built space and its boundaries, of an era before pandemics, and before, even, the Influenza pandemic of 1917 to which we reached back for bearings in search for a precedent for reactions to the spread of COVID-19, and how the pandemic was challenging modern notions of transmission, contagion, science and even space.

I gathered names on the ground as if points of orientation, finding stamps and strikes of pavers whose names were set in the pavement with century ago an alternate register of mortality. The dizzying sense of temporal distance offered a perspective a century ago–before the 1918-20 pandemic of the “Spanish” Flu entered California, were somehow a distance on our own sense of modernity and the disarming unpreparedness for the pandemic, which seemed as if we were entering a new era, and indeed one of historical rupture. As if a new historical epoch, of an end of confidence of modern control over the spread of disease, whether of the control of inter-species jumps of viruses, and a new range of “zoonotic” diseases, or the mutation of the new viruses that arose, if not from global warming, from

Early pavers’ names are a bit ubiquitous in many of the older residential neighborhoods of Berkeley, CA, where the developers of lots seem to have regularly paved sections of sidewalks for tracts where houses were built, giving them on odd patchwork nature, and resulting in pavements that are often repositories of information of historical development and the segregation of areas.

which I read as if I were uncovering an often unread archive paved beneath my feet in the micro-geography of my neighborhood, in images with only retrospective senses of clarity, as we tried to come to terms with the historic nature of the pandemic’s spread. Strikes left by early pavers–“Burnham-1908;” “F. Stolte-1930;” “P. Barelle-1938;” “J. Anderson 1936”–of names and dates presented as epigraphic evidence beneath my feet akin to levels of time, v snapshots of a stratigraphy of the Berkeley-Oakland neighborhood I lived, “Burnham” resonantly echoing that of a contemporary urban planner, as I gathered evidence about the area I wandered, as if it were a profession.

For if earlier years of the possible pandemics feared to spread globally had been numerous–near-misses of the fear of H1N1 expanding globally in 2009, of MERS in 2013, Ebola in 2014, and Zika in 2016–the coronavirus spread in ways unseen since the avian-born pandemic of 1918-19, harder to map, track, or conceptualize; visualizing the virus became a cottage industry and a collective rush to create the best visualizations possible. As I tried to retreat from the spread of infections and hospitalization, and indeed the growing uncertainty of both tallies, the dates beneath by feet on the pavements along the Oakland-Berkeley border provided a form of retreat, pavement punctuated by dates that seemed–1909; 1923; 1938; 1930–to mark a sense of the anonymous architects of this urban border. With less of a sense of transport and reverie than Walser, if with a similar dedication to what he called, only partly facetiously, his berĂĽf–“without walking, I would be dead, and my profession would be destroyed”–the sense of opening oneself to “thinking, pondering, drilling, digging, speculating, investigating, researching, and walking” gained a sense of investigating the quite deep history of breaks in neighborhoods in the micro-geography that I started to examine as etched in concrete. Whoever “walks only half-attentive, with only half his spirit . . . is worth nothing,” Walser said of the dedication he assumed, while walking, attentive to houses, advertisements, social transactions, as if to re-familiarize himself with the world as a therapy–to “take fresh bearings,” with a degree of industry, as a “Field Marshall, surveying all circumstances, and drawing all contingencies and reverses into that net of his,” in a calculus of metropolitan space, if with far fewer social transactions–but in fact mostly to “maintain contact with the living world,” lest we be shut at home, before the virtual remove of Zoom.

The paving of the street that defined the edge of the exclusive Oakland neighborhood formerly a farm until 1905–set aside for an upscale residential community–had been paved by the local quarry in 1912. The date gave me new bearings on the present, that gained a spiritual side, as well as a form of taking bearings: Walser found a microcosm of the world and lovely homes, “walking and contemplating nature,” richer than what Walter Benjamin cast as “botanizing the pavement,” albeit a lovely phrase–for me, the collection of older marks on the pavement began as a curiosity, but turned to navigating historical levels inscribed in a surface as lines of exclusion and inclusion that the earliest dated pavers’ strikes bore witness, and made up for the few numbers of people on the street, in what seemed among the earlier surviving sidewalks that were paved in the this neighborhood.

The paving of this Oakland-Berkeley area was defined by early residential zoning, restricting local populations to whites and often by income, effectively, and expressed in stipulations of residential home-ownership. The border was increasingly legible in the local maps of mortality and COVID-19 infections. Putting into relief my sense of the fuzzy border of gentrification, one could not be struck by the discrepancy of increased infections-as, later, increased vaccination rates–between Berkeley and Oakland. The barrier seem, in my own neighborhood, loosely defined, but defined different expectations and experiences of the virus, poorly understood if only read by that odious term, concealing so much, of “comorbidities.” As we discussed how much the novel coronavirus was indeed a sort of rupture, or how significant COVID-19 was both epidemiologically and, at a deeper level, historically–wondering if the possible narrative of an endpoint of escalating infections would be a return to “normal,” or if “normal” really made sense as a place to return–the architecture of this local municipal border seemed to make sense as something I sought. to decipher in what might be called, perhaps uncharitably, an episode of pandemic flânerie, or a search for a space for reflection and a hope for distance that city walking might offer to cope.

Did it make sense to look retrospectively at the ‘Spanish’ Flu, or why no historical ruptures were created by its spread? The maps offered a chilling reminder of the difficulty of stopping its spread to populated areas, across the nation, that was oddly comforting in the progression of pandemics over space if haunted by rising curves of mortality. And as we watched our own time-series graphs of the temporal progression of rates of death and mortality, questioning the undercounts, role of co-morbidities, and trying to peak under the hood of the data visualizations to grasp its spread, the dizzying global scale of infection rates, hospitalization rates, and mortality rates gave us all on the fly crash-courses in demography and epidemiology which we had to admit our grasp was pretty unclear. The learning curve was so daunting, if so basic, that it seemed for a historian more important to gain distance in the past, and preceding pandemics.

Second Wave of “Spanish” Flu Reaches California as it Spreads across America, 1918

As we tried to map the progress of the coronavirus, its origins, and contraction in different rates, we turned with security to the clearest form of visualizing the pandemic, the time-tested time-series line graph, that basic tool of visualization most fit for something so daunting as mortality, which had been a basis for tallying the estimated total of the fifty million killed in the 1918-19 “Spanish” Flu pandemic, a tally of mortality we would later approach. While the 1918-19 pandemic was a removed event, the curves of mortality on time-series graphs tracked a sense of the compression of deaths to a linearity of time; rates were tallied weekly of the avian-born pandemic in an eerily identical graphic space of data visualization, which was echoed in the similar kinship of tools adopted to contain its spread–masks, hand washing, quarantine–as tracking the progression of time across the old x-axis and the rates of hard to comprehend escalating deaths along the y-axis distanced them with a helpful sense of anonymity.

Spanish flu

As much as we were braced by how the progress of the pandemic revealed vulnerabilities of public health systems, the pandemic had posed stress test of the global information network–both in charting and sharing information about infections and identification of the coronavirus genome, and in educating the public about its treatment, and locating access to accurate sources of information.

The difficult to process nature of arranging these humblest of graphs in terms of total cases of COVID-19–a basic tally, but one hard to say was accurate; new cases per day, a metric that seemed to suggest how much of a handle we had on the pandemic’s spread; confirmed cases per million; or the rates of infection in different nations, that oddly removed the spread of mortality as if we were viewing the challenge of combatting the virus as a spectator sport. Due to the official public denial of its danger or threat in the United States, and in the proliferation of online newsletters, uneven public tracking of infection rates by the CDC, multiple sources of ostensibly authoritative advice from whether it was healthy to exercise outdoors given the dangers of droplet dispersal from others, needs for frequent hand washing or gel disinfectant, and dangers of pubic space grew. We moved through space differently, in the Bay Area, projecting to different degrees a cone of six feet distance, internalizing distance as a social good as we sought to remeasure our relation to a fractured social body.

Coronavirus Advances

While we are increasingly deadened by data visualizations that track the infectious spread of COVID-19 across the world and country, their logic has often been implicit. As much as tracking real-time data of deaths and “hot-spots” in the world and the nation, we trust the data viz to orient us to the infectious landscape to better gain understanding of viral spread. We seek to grasp nature of the virus’ transmission, and perhaps hope that we can better grasp its spread. We depend on these daily updates to retain a sense of agency in the chaos, but realize that they are provisional, contingent, and selective snapshots, based on testing, and exist at a time delay from the virus’ actual distribution–without much predictive value. We maddeningly realize they are dependent on testing rates and reporting, and only as good as the datasets which they re-present.

On the heels of a 5% statewide positivity rate on December 5, 2020, California was declared in a state of shut down in all its counties. It almost seems that such graphics have started to fail us, as the spread of the virus overflows the boundaries of the map and permeates its space. The choropoleth renders individual counties all but indistinct, the state drowned in widespread infections, with only a few of its less populated regions as refuges. With a flood of purple overflowing the coastal counties, the delta, the Central Valley, and the entire south of the state, was there even any point in mapping the danger of viral spread beyond a state of red alert?

Dec. 5, 2020

While mapping offers little comfort in the era of saturation of heightened risk, the color-codes alert inhabitants to the danger of increased stresses on the public health system–as much as visualization challenges to translate tools of data aggregation to visualize the pandemic., as December 6 rates grew by December 19. As we shift to map a decreasingly multi-colored state by the moderate, substantial and widespread virus, and widespread cases seem to flood the state, the map offers a security of some sort of monitoring of the pandemic’s spatial spread.

The sea of purple is like Spinal Tap going raising the volume “up to eleven,” and are a sign that we are in unexplored territory that won’t be accommodated by a simple color ramp–or, indeed, a familiar cartographic iconography among our current tools of styling space. While we are used to maps embodying meaning, what the colors of the map embody–beyond risk–is unknown. To be sure, at a time when fatalities from the coronavirus in the south of the state have skyrocketed from the middle of the month, hitting records in ways terrible to even contemplate, the field of purple is a deeply human story of loss, as a surge of hospitalizations have flooded the entire healthcare community, and stretched facilities of critical care beyond anything we have known, filling half of intensive care beds in LA County at Christmas. 2020 enough to make it hard to feel any relief in the close of a calendar year, as if that unit still held any meaning, and very grim about 2021: and while the CDC allowed that there may already be a new, more contagious strain, in the nation two days before Christmas, the arrival of the more contagious strain in California and Colorado increased alarm before New Year’s.

How to get a handle on the novel coronavirus that we have been pressing against COVID-19 dashboards since March to grasp better, and will we able to do so in 2021?

Whatever sense agency the maps impart, it is an agency that is only as good as the compromised sense of agency that we expect in an era of geolocation, on which most maps track reports of infection. Even as we face the rather grim warning that we are waiting for the arrival of a vaccine that, in the Bay Area, rates of immunization face steep obstacles of vaccine distribution due to pragmatics of freezer space required, training of extra health care workers, and monitoring and tracking the two-stage process of vaccination, we will depend for public sanity on maintaining clear communication in maps. The actual tracking of the novel coronavirus doesn’t translate that well to a state-wide model, or a choropleth, although it is the method for public health advisories that makes most sense: we do not have small-scale public health supervision in most of the nation, although they exist at some counties. The stressed Departments of Public Health in areas are without resources to manage COVID-19 outbreaks, public health compliance, or retaliations for public health violations: and the effort to create public health councils to manage compliance and violations of public health orders may be seen by some as an unneeded bureaucracy, but will give local governments resilience in dealing with an expanding epidemic, at the same time as governmental budgets are stressed, and no body of law about COVID violations exists.

Rather than map on a national or state-wide level, we can best gain a sense of how much virus is out there and how it moves through attempts of contact tracing–even if the increasing rates of infection may have gone beyond the effectiveness of contact tracing as a methodology that was not quickly adapted by a federal government the prioritized the rush to a vaccine. The basis for such a map in LA county can reveal the broad networks of contagion, often starting in small indoor gatherings across the region, and moving along networks of spatial mobility across the city and San Fernando Valley, and help embody the disease’s vectors of transmission as we watch mortality tallies on dashboards that give us little sense of agency before rising real-time tolls.

ESRI

If such ESRI maps suggest a masterful data tracing and compilation project, the data is large, but the format a glorification of the hand-drawn maps of transmission that led to a better understanding of the progress of Ebola on the ground in 2014, used by rural clinics in western African countries like Liberia and Rwanda to stop the infectious disease’s transmission and monitor the progress of contagion to limit it–as well as to involve community members in the response to the virus’ deadly spread.

We may have lost an opportunity for the sort of learning experience that would be most critical to mitigate viral spread in the United States, as no similar public educational outreach was adopted–and schools, which might have provided an important network for diffusing health advisories to families, shifted predominantly to distance learning and providing meals, but we became painfully aware of the lack of a health infrastructure across America, as many openly resisted orders to mask or to remain indoors that they saw as unsubstantiated restrictions of liberty, not necessary measures.

Hand-Drawn Public Health Map of Ebola Transmission in Liberia (2014)

We are beyond contact tracing, however, and struggling with a level of contagion that has increased dramatically with far more indoor common spaces and geographic mobility. Yet the broad public health alerts that these “news maps” of viral spread offer readers omits, or perhaps ignores, the terrifying mechanics of its spread, and the indoor spaces in which we know the virus is predominantly acquired. The rise of newly infectious mutated strains of the novel coronavirus was in a sense inevitable, but the rising tension of what this means for the geographical distribution and danger of the coronavirus for our public health system is hard to map to assess its wide distribution, and we take refuge in mitigation strategies we can follow.

Why have we not been more vigilant earlier to adapt the many indoor spaces in which the virus circulates? It bears noting that the spread of virus in the state was undoubtedly intensified by over a hundred deaths and 10,000 cases of infection to spread in the density of a carceral network, which seems an archipelago incubating the spread of viral infections in the state. We only recently mapped the extent of viral spread across nineteen state prisons by late December 2020, tracked by the Los Angeles Times, but often omitted from public health alerts–

Coronavirus Cases Reported in Nineteen California Prisons, Dec. 21, 2020

–and the density of Long-Term Care centers of assisted living across the state, which were so tragically long centers of dangers of viral spread, as the New York Times and Mapbox alerted us as the extreme vulnerabilty of elder residents of nursing homes, skilled nursing facilities, retirement homes, assisted-living facilities, residential care homes who cannot live alone was noted across the world. The data that was not provided in the grey-out states interrupted the spread of infections among those often with chronic medical conditions was not surprising, epidemiologically, but terrifying in its escalation of the medical vulnerability of already compromised and vulnerable populations–and steep challenges that the virus posed.

unlike those greyed out states that fail to release data on deaths linked to COVID-19 infections, congregate on the California coast: while the New York Times depicted point-based data of the over 100,000 COVID-related deaths in nursing homes are a small but significant share of COVID deaths, exposure for populations with extraordinarily high probability of possessing multiple possibilities for co-morbidities is probably only a fraction of infections.

Coronavirus Deaths linked to Nursing Homes in United States, December 4, 2020

We strain to find metrics to map the risk-multipliers that might be integrated into our models for infectious spread. It seems telling to try to pin the new wave of infections in a state like California to increased contact after Thanksgiving–a collective failure of letting up on social distancing in place since March–as the basis for a post-Thanksgiving boom in many regions of the state, using purely the spatial metrics of geolocation that are most easily aggregated from cell phone data in the pointillist tracking of individual infections in aggregate.

New York Times/CueBiq Mobility Data

Based on cell-phone data of geolocation, a proxy for mobility or social clustering that offered a metric to track Americans’ social proximity and geogarphical mobility–including at shopping centers, oceanside walks in open spaces, and even take-out food curbside pickups, as well as outdoor meals and highway travel, few counties curbed aggregation as one might hope–although the fifty foot metric accepts the many outdoor congregations that occurred, well within the Cuebiq metric, wearing or without masks. A magenta California registered pronounced proximity, grosso modo, discounting any mindful innovative strategies in the state.

Increased Spatial Closeness within Fifty Feet/CueBiq/Graphic NBC News, Nigel Chiwaya and Jiachan Wu

It is stunning to have a national metric for voluntary mobility, rough as it is, to measure internalization of social distancing protocols and potential danger of a post-holiday COVID-19 bump. To be sure, we are stunned by geolocation tools to aggregate but risk neglecting the deeper infrastructures that undergird transmission, from forced immobility. While geolocation tools offer opportunities for collective aggregating whose appeal has deep historical antecedents in measuring contagion and anticipating viral transmission by vectors of spatial proximity, geospatial tools create a geolocation loop in visualizations which, however “informative” perpetuate a spatiality that may not clearly overlap with the actual spatiality of viral transmission.

Even if we demanded to map what were the novel coronavirus had “hot-spots” in mid- to late March, as if processing the enormity of the scale we didn’t know how to map, aggregating data without a sense of scale.

March 26, 2020

Across the summer, it seems best to continue to map daily numbers of cases, relying on whatever CDC or hospital data from Hopkins we had, trying to aggregate the effects of the virus that was spreading across the country whose government seemed to provide little economic or medical plan, in maps that tallied the emergence of new cases, as new hotspots appeared across the land, meriting attention difficult to direct.

We are plowing infections and mortality with abandon in a steady diet of data visualizations that purport to grasp disease spread, that were once weighted predominantly to the New York area, even as they spread throughout the nation by the end of March, but remaining in the thousands, at that point, as even that low threshold was one by which we were impressed. The tracking of the local incidence of reported cases seemed to have meaning to grasp the meaning of transmission, with a pinpoint accuracy that was assuring, even if we had no way to understand the contagion or no effective strategy to contain it. But we boasted data visualizations to do so, focussing on the nation as if to contain its spread in antiquatedly national terms, for a global pandemic, not mapping networks of infection but almost struggling to process the data itself.

After all, the John Snow’s cholera maps of John Snow are the modern exemplars foregrounded in data visualization courses as game-changing images as convincingly precise pictures of infection progressing from a water pumps in London neighborhoods is often seen as a gold standard in the social efficacy of the data visualization and information display. The elevation of the pinpoint mapping of cholera mortality in relation to a water pump from which the deadly virus was transmitted in a nineteenth-century London neighborhood:

John Snow, “Cholera Deaths in Soho”

The Snow Map so successfully embodies a convincing image of contagion that it has taken on a life of its own in data vis courses, almost fetishized as a triumphant use of the plotting of data that precisely geolocated mortality statistics allow, and can indeed be transposed onto a map of the land to reveal the clustering of death rates around the infamous Broad St. pump, that created a legible vector of the transmission of diseases in the Soho neighborhood, so convincing to be touted as a monument of the data sciences.

Open-Air Water Pumps Tainted by Cholera measured in John Snow’s Map

Snow is lauded for having effectively showed that, in ways that changed scientific practices of collective observation and public health: rather than being communicated by miasmatic infections that spread to low-lying London from the Thames, mortality rates could gain a legibility in proximity to a pump that transmitted an infectious virus, often presented as a conceptual leap of Copernican proportions (which it was, when contrasted to miasma that emanated from the Thames to low-lying areas–if it anticipated a bacteriological understanding of viral transmission). The association of danger with the water procured on errands from neighborhood pumps however replaced the noxious vapors of a polluted river, as in earlier visualizations of the miasma that lifted the noxious fumes of the polluted Thames river to unfortunate low-lying urban neighborhoods, who were condemned by urban topography to be concentrations of a density of deaths of more striking proportions and scale than had been seen in the collective memory.

Snow made his argument by data visualizations to convince audiences, but he mapped with a theory of contagion. But if Snow’s maps works on how the virus is communicated in outdoor spaces–and how a single site of transmission can provide a single focus for the aggregation of mortality cases, COVID-19 is an infection that is most commonly contracted in indoor spaces, shared airspace, and the recycled unfiltered air of close quarters. And the indoor spaces where COVID-19 appears to be most often transmitted stands at odds with the contraction in outdoor common spaces of the street and service areas of water pumps, that create the clear spacial foci of Snow’s map, and the recent remapping by Leah Meisterlin that seeks to illuminate the urban spaces of the contraction of cholera in a digital visualization as a question of intersecting spatialities.

Current visualization tools compellingly cluster a clear majority of cholera deaths in proximity to a publicly accessible pump where residents drew water where viral pathogens that had colonized its handle. But we lack, at this point, a similarly convincing theory of the transmission of the novel coronavirus SARS-CoV-2.

But the logics of COVID-19’s communication is nowhere so crisp, and difficult to translate to a register that primarily privileges spatial contiguity and proximity–it is not a locally born disease, but a virus that mutates locally across a global space: a pandemic. And although contact-tracing provides a crucial means of trying to track in aggregate who was exposed to infection, we lack any similarly clear theory to metaphorically grasp the contagion–and are increasingly becoming aware of the central role of its mutation to a virus both more infection and that spreads with greater rapidity in confronting the expansive waves of infection in the United States–as if an escalated virulence grew globally in the first months of this rapidly globalized pandemic.

Our dashboards adopted the new versions of web Mercator, perhaps unhelpfully, to offer some security in relation to the nature of viral spread, which, if they served as a way of affirming its truly global scope–

NextStrain

–also suggested that global traffic of the virus demands its own genomic map, as the virus migrates globally, outside strictly spatial indices of global coverage, and that perhaps spatial indices were not the best, in the end, for accounting for a virus that had began to develop clear variants, if not to mutate as scarily as many feared, into a more virulent form.

And it may be that a genomic map that allow the classification of viral strains of genomic variability demand their own map: for as we learn that genomic mutation and variation closely determines and affects etiology, communication of the viral strains offers yet a clearer illustration that globalization articulates any point in terrestrial space to a global network, placing it in increased proximity to arbitrary point not visible in a simple map, but trigger its own world-wide network of markedly different infectiousness or virulence.

NextStrain

From December 4 2019, indeed, we could track emergent variants of the virus best outside of a spatial scale, as much as it reminded us that the very mobility of individuals across space increased the speed and stakes of viral contagion, and the difficulty to contain viral spread, in the interconnected world where viral variation recalled a flight map, set of trade routes, or a map of the flow of financial traffic or even of arms. Mutations were understood to travel worldwide, with a globalism that a spatial map might be the background, but was indeed far removed, as we moved beyond questions of contact tracing to define different sizes of genomic mutation and modifications that we could trace by the scale of mutations, not only the actual places where the virus had arrived.

Was place and space in fact less important in communicating the nature of COVID-19’s increasing virulence?

The maps of genomic variation traced not only the globalization of the virus, but its shifting character, and perhaps etiology across some thirty variants by late April, that show both the global spread of the virus, and the distinct domination of select strains at certain locations, in way that researchers later theorized the ability to “track” mutations with increasing precision. If researchers in Bologna defined six different variants of coronavirus from almost 50,000 genomes that had been mapped globally in laboratory settings to map variants of the virus whose signatures showed little more variability than strains of the flu in June, variations of signatures seemed a manner to map the speed of coronavirus that had traveled globally from by February 202 to the lungs of the late Franco Orlandi, an eighty-three year old retired truck driver from Nembro, Italy, whose family could not place China on a map when, following diagnostic protocol, attendant physicians in Bergamo asked if Orlandi had, by chance, happen to have traveled to China recently.

NextStrain

Despite lack of serious mutation, thankfully, the data science of genomic sequencing of the COVID-19 cases triggered by genomic mutations of SARS-CoV-2 genome of just under 30,000 nucleotides, has experienced over time over 353,000 mutation events, creating a difficult standard for transmission into equivalent hot spots: some hot spots of some mutations are far more “hot” than others, if we have tried to plot infections and mortality onto race, sex, and age, it most strikingly correlates to co-morbidities, if all co-morbidities are themselves also indictors of mortality risk. While the mutations have suggested transmission networks, have the presence of different levels of mutations also constantly altered the landscape of viral transmission?

Global Distribution of Sars-CoV-2 Variants, March 15, 2020/Los Alamos National Laboratory

It makes sense that the viral variant was tracked in Great Britain, the vanguard of genomic sequencing of the novel coronavirus as a result not only of laboratory practices but the embedded nature of research in the National Health Services and the monitoring of public health and health care. Enabled by a robust program of testing, of the some 150,000 coronavirus genomes sequenced globally, England boasts half of all genomic data. Rather than being the site of mutations, Britain was as a result the site where the first viral variant was recognized and documented, allowing Eric Volz and Neil Ferguson of Imperial College London to examined nearly 2,000 genomes of the variant they judged to be roughly 50% more transmissible than other coronavirus variants, magnifying the danger of contagious spread in ways feared to unroll on our dashboards in the coming months. As teams at the London School of Hygiene and Tropical Medicine studied the variant in late 2020 in southeast England, they found it to be 56% more transmissible than other variants, and raised fears of further mutations in ways that rendered any map we had even more unstable.

The virus SARS-CoV-2 can be expected to mutate regularly and often. While England boasts about half of all global genomic data on the virus, of the 17 million cases of SARS-CoV-2 infections in the United States, only 51,000 cases of the virus were sequenced–and the failure to prioritize viral sequencing in America has exposed the nation to vulnerabilities. And although California has sequenced 5-10,000 genomes a day of the novel coronavirus samples by December, and Houston’s Methodist Hospital have mapped 15,000 sequences as it watches for new viral variants; an American Task Force on viral variants will be rolled out early in 2021, as the discovery of viral mutations haves spread across five states in the western, eastern, and northwestern United States. While it is not clear that the viral variant or mutations would be less susceptible to polyclonal vaccines, most believe variants would emerge that would evade vaccine-induced immunity.

Earth, Wind, and Fire

We think of earth, wind and fire as elements. Or we used to. For the possibility of separating them is called into question in the Bay Area, as wind sweeps the smoke of five to seven fires, or fire complexes, across the skies, we are increasingly likely to see them as layers, which interact in a puzzle we have trouble figuring out. Indeed, the weirdly haunting daily and hourly maps of air quality map the atmospheric presence of particulate matter by isochrones brought late summer blues to the Bay Area. Blue skies of the Bay Area were colored grey, burnt orange, and grey again as cartoon plumes of soot flooded the skies in a new sort of pyrocumulus clouds that turned the sun red, offering a disembodied traffic sign telling us to stop.

Clara Brownstein/October 1, 2020

Fire season began by remapping the town in terrifying red that registered “unhealthful,” but almost verging on the “hazardous” level of brown, based on local sensors monitoring of ozone, but is also registering a deeper history defined by an absence of rain, the lack of groundwater, the hotter temperatures of the region and the dry air. The map is both existential, and ephemeral, but also the substrate of deep climate trends.

AQI Chart on Saturday, August 22, 2020/AirNow (EPA)

Is fire an element we had never before tracked so attentively in maps? We did not think it could travel, or had feet. But wildfire smoke had blanketed the region, in ways that were not nearly as visible as it would be, but that the real-time map registers at the sort of pace we have become accustomed in real-time fire maps that we consult with regularity to track the containment and perimeters of fires that are now spreading faster and faster than they ever have in previous years. And soon after we worried increasingly about risks of airborne transmission of COVID-19, this fire season the intensity of particulate pollutants in the atmosphere contributed intense panic to the tangibility of mapping the pyrocumulus plumes that made their way over the Bay Area in late August. As the danger of droplets four micrometers in diameter remaining airborne seemed a factor of large-scale clusters, the waves of black carbon mapped in the Bay Area became a second sort of airborne pathogen made acutely material in layers of real-time Air Quality charts.

The boundaries of fire risk charts and indeed fire perimeters seemed suddenly far more fluid than we had been accustomed. When we make our fire maps with clear edges, however, it is striking that almost we stop registering the built environment, or inhabited world. As if by the magic of cartographical selectivity, we bracket the city–the sprawling agglomeration of the Bay Area–from the maps tracking the destructiveness and progress we call advancing wildfires, and from the isochronal variations of air quality that we can watch reflecting wind patterns and air movements in accelerated animated maps, showing the bad air that migrates and pool over the area I life. The even more ephemeral nature of these maps–they record but one instant, but are outdated as they are produced, in ways that fit the ecoystem of the Internet if also the extremes of the new ecosystem of global warming–the isochrones seem somewhat fatalistic, as they are both removed from human agency–as we found out in the weeks after the Lightning Siege of 2020 that seemed a spectacle of the natural world that rivaled the art of Walter de Maria in their grandiosity of time-lapse photography–

Shmuel Thaler, CZU Lightning Strikes
Walter de Maria, Lightning Field, 1977
Shmuel Thaler, CZU Complex (2020), detail

–the horizontal line of artificial light from Santa Cruz, unlike the images that De Maria created from The Lighting Field, remind us of the overlap between inhabited spaces where conflagrations in the dry wildlands that spread as the fires struck, and in way far less difficult to aestheticize than The Lightning Field set in a desert removed from human population, but was built as an isolated field for time-stop photography.

The CZU complex brought widespread devastation across areas of extra urban expansion in the Santa Cruz Mountains was almost a map that registered the expansion of residences to the very borders of forests. We haven’t ever faced the problem of maintaining and clearing in weather this dry, even if we have mapped the clustering of fires in the wild land-urban interface: but the strikes ignited underbrush lain like kindling, on the boundaries of the raging fire complexes. If the burning of underbrush by fire mitigation squads seeks to create fire lines in the mountainous landscape to create new perimeters to forestall the advance of major fires, working along a new fire line even as what is still called wildfier smoke travels across the nation, far beyond the Bay Area.

While watching the movement of fires that them in inhabited areas like shifting jigsaw pieces that destroy the landscape across which they move. These marked the start of megafires, that spread across state boundaries and counties, but tried to be parsed by state authorities and jurisdictions, even if, as Jay Inslee noted, this is a multi-state crisis of climate change that has rendered the forests as fuel by 2017–for combined drought and higher temperatures set “bombs, waiting to go off” in our forests, in ways unable to be measured by fire risk that continues to be assessed in pointillist terms by “fuel load” and past history of fires known as the “fire rotation frequency.” When these bombs go off, it is hard to say what state boundary lines mean.

Fire Threat Risk Assessment Map, 2007

If San Francisco famously lies close to natural beauty, the Bay Area, where I live, lies amidst of a high risk zone, where daily updates on fire risk is displayed prominent and with regularity in all regional parks. These maps made over a decade ago setfire standards for building construction in a time of massive extra-urban expansion. But risk has recently been something we struggled to calculate as we followed the real-time updates of the spread of fires, smoke, and ash on tenterhooks and with readiness and high sense of contingency, anxiety already elevated by rates of coronaviurs that depended on good numbers: fire risk was seen as an objective calculation fifteen years ago, but was now not easy to determine or two rank so crisply by three different shades.

Fire Risk Map, 2007

When thunderstorms from mid-August brought the meteorological curiosity of nearly 12,000 dry lightening dry strikes from mid to late August 2020, they hit desiccated forests with a shock. The strikes became as siege as they set over three hundred and fifty-seven fires across the state, that rapidly were communicated into expansive “complexes” of brush fires.

We map these fires by state jurisdictions, and have cast them as such in policy, by borders or the perimeters we hope to contain barely grasp the consequences of how three quarters of a million acres burned up suddenly, and smoke from the cluster of fires rose in columns that spread across state boundary lines as far as Nebraska, and how fire complexes that spread across three million acres that would soon create a layer of soot across the west, eerily materialized in layers of GIS ESRI maps of environmental pollutants, while toxic particulate mater released in plumes of black carbon by the fires cover the state, rendering the sun opaque where I live, in the Bay Area, now Pompeii by the Bay as smoke at toxic levels blanketed much of the state.

They even more serious map, to be sure, was of fire spread: but the maps of air quality set the entire western seaboard apart from the nation, as if threatening to have it fall into the ocean and split off from the United States,–even if the burning of its open lands was more of a portent of things to come, they were a historical anomaly, lying outside the record of fire burns or air quality, if the poor air quality traced the origin of black carbon columns of smoke that would rise into the nation’s atmosphere.

Cartographies of Covid-19: Unclear Paths Forward

A pandemic is by its nature both local and global by definition–and begins from a local outbreak. But if the only way to gain orientation to a pandemic is by accurate local counts, the problem of balancing–or toggling between–the local and global has become staggeringly pronounced in the case of COVID-19, as if the point-based cartography that we use to track the disease has the better of us, and upper hand, with the absence of accurate local counts. The lack of clear data that came from Wuhan in the days that followed the outbreak of the virus revealed worrisome problems of transparency. The difficulties Chinese government authorities faced in getting bearings on the zoonotic virus, lab-born or not, raised problems of even trying to map its rise, and we tired to look at maps as tea-leaves of future responses, as well as retrospective diagnoses of the point of origin of disease spread–as if maps could explicate our uncertain conditions, and increased vulnerability.

Data visualizations since seem to proliferate in response to uncertainty and an absence of consensus, as we turned to maps as a hope for truth in an age of increased uncertainty: as local officials were loathe to shoulder responsibility, the tally of infected in Hubei Province jumped, astoundingly, forcing the government to recognize the ease of its transmission among humans, was far more virulent than believed. But at this point, looking back in the mirror provides little sense of orientation to the multiplication of dispersed local outbreaks of coronavirus that we are increasingly challenged to map in relation to ourselves. Were the first maps of the New World similar responses to the deep sense of religious and eschatological uncertainty of the early modern period? Whether or not that was the case, we all felt especially early modern now, plague victims of a sort that led us to look back on the mapping and mapping of responses to the spread of pestilence, and hoping that past experience–or our current increased ability of empathy–gave us more meaningful access to the epidemics and pandemics of the past.

The sudden uptick of cases reveals a reticence in tallying the infected out of fears of reprisals for apparent incompetence, an institutional blame-shifting triggering mechanisms of concealment that has led American meat-packing plants to hide numbers of infected workers, and numbers of tests for infection to be far lower than official records suggest: the absence of ability to control the spread of SARS-CoV-2 led us to proliferate maps in hopes to grasp its rapid doubling, uncomfortable at the world they began to show, apprehensive at how to come to terms with the rapidity of local outbreaks of confirmed cases with sufficient granularity, and enough continuities, hoping to track contagion as hopes of containment were beginning to fade in the new aggregates that were increasingly evident.

New York Times

The warning of the virus’ spread was raised by Li Wenliang on December 30 from Wuhan, inter-agency shifting of blame and responsibility in Wuhan– a reflexive institutional blame-shifting by “throwing woks”–abruptly ceased with summons of Shanghai Mayor Ying Yong, he who lured Elon Musk to Shanghai, to restore order: as a new hospital was built, tallies of new cases of coronavirus in Hubei astronomically grew by nine from 1,638 to 14,840, shocking the world–a figure was in keeping with the nearly 1,400 people dead in the country, but suggesting a viral load of unprecedented proportions. Americans apprehensively watched the disease afflicting passengers of cruise liners as if it would arrive ashore, its virulence was in fact already of pandemic proportions: yet American disinformation here took over, as we were told to stick our heads in the sand, ostrich-like, as fears were overblown, and tried to keep calm. And then, the tables were turned, as the United States President described, or suggested, a national policy of intentional undercounts, and limited testing, lest the counts discovered tank his popularity–the stock market value of Trump, International, or, rather, Trump-in-Office, Trump-as-Chief-Executive, whose new season might be canceled due to low ratings. And although the virus began in China, how the United States increasingly came to be the outlier in the numbers of infection confirmed weekly suggested a national story of mismanagement, as the narrative we told ourselves of American exceptionalism before illness seemed to have boomeranged, with the three-day averages of confirmed infections skyrocketing, and setting us apart from the very nations we compare ourselves to, but whose health-care policy we increasingly realize we are distinct from.

Americans were soothed by deceptive common-sense talk. But the results of a lack of investment in public health are all too evident, if our maps are . Robert Redfield, a virologist who served as the public spokesperson of reassurance who had long sustained false theories about retroviruses causing HIV and AIDS, argued that even if the fourteen confirmed cases of the novel coronavirus were monitored and traced, “the virus more exploded . . beyond public health capacity,” he seemed to forget he had not developed that capacity. Virology is of course Dr. Redfield’s area of expertise, but he won his political post in no small part by being practiced in massaging truth statements for political ends. During AIDS outbreak, the last major plague in the United States, he had advocated unproven drugs billed as HIV vaccines and encouraged quarantine, abstinence, and stripping the medical licenses of HIV-infected medical workers, more than accelerating cures; Redfield took time to blame the Obama administration for implementing clinical tests, to please his patron. Bt he obscured the level of infections that in truth were not known, blinding the nation to a cartography of COVID by not advancing adequate levels of testing, that returned us to the simple equation of the dog days of AIDS, only able to make us yell, yet again, this time with Larry Kramer, stalwart resistor of the silencing of AIDS by the failure to use on-trial medicine–

–at the utter deception with which we met the pandemic. Dr. Redfield must have met his commission to radiate calm by assuring Americans in late February. As he assured us only fourteen cases had been diagnosed in the United States, the number meant little, as any virologist should kmow; while hindsight is a benefit that obscures us from the need to life life forwards, we suspect urban hotspots were already laden with infected individuals by March 1, a silent ticking bomb of urban outbreaks already infecting 28,000 as it spread broadly its “hotspots”–New York, Chicago, San Francisco, Seattle, Boston and Chicago–all of massively different density, without tests being able to affirm the scale of its spread.

There was no map. And then, all of a sudden, the globalization of coronavirus hit home; any place in the world could be related to any other place, as rates of infection bloomed globally in geographically disjointed hotspots, spatially removed from one another, even as a standard for uniform testing lacked. And there was no sense of an art of dying, as the amazingly rapid contraction and worsening of illnesses left many without a script, and many more silent before a dizzying multiplication of statistics of mortality in the face of COVID-19, several weeks later.

Every other map of COVID-19’s spread seems an attempt to persuade the viewer of its accuracy and totality, in retrospect, even as we have no clear sense of the total figures of infection-or even of the paths infection takes. We are mystified by the geography and spatial dynamics of the virus’ travel, but realize the severe communicability of a virus whose load is stored in the naso-laryngeal passages, and can be communicated by airborne drops. Is distancing the best way we can constrain the geographic spread of infection? Can statistics demonstrate the success of curtailing its spread?

It was a hidden agenda in the maps of news agencies and to register the accurate levels of infection, promising the sorts of transparency that had been clouded in much of January. And while we watch the progress of the pandemic on screens, there is a sense of truth-telling, as a result, of revealing the scope of the virus’ actual spread that compensates for the lack of clarity we once had. But it is also increasingly difficult to orient ourselves to the GPS-enabled scales of its spread, for we still are looking at pretty limited and almost superficial data, in the sense we have trouble plotting it in a narrative context, or find a reaction more than shock. The virus is easy in ways to personify as a threat–it wants us outside; it comes from afar; it pervades public spaces and hospital grounds; it demands vigilant hand-washing and sanitizing–but the very numbest are elusive. While we try to track reported cases, hoping that these limited datasets will provide orientation, we have been lumping numbers of tests that might be apples and oranges, and have not found a consistent manner of testing. Deaths are difficult to attribute, for some, since there are different sites where the virus might settle in our bodies.

Even while not really following the pathways of its transmission, and the microscopic scale of the progress of the pathogen in bodies. And if we rely on or expect data visualizations will present information in readily graspable terms, we rarely come to question the logics that underly them, and the logics are limited given the poor levels of global testing for COVID-19. It is frustrating that our GPS maps, which we seem able to map the world, can map numbers of surrogates for viral spread, but we have yet to find a way to read the numbers in a clear narrative, but are floored by the apparently miasmatic spread of such a highly contagious disease that makes us feel, as historian of science Lorraine Daston put it, that we are in “ground zero of empiricism,” as if we are now all in the seventeenth century, not only in being vulnerable to a disease far less dangerous or deadly than Yersina pestis, but without explanatory and diagnostic tools.

This was, to be sure, a past plague come to life, requiring new garb of masks, face-shields, and protective gear for health workers–

–as the cloaks, leather gloves, staffs and masks that made up early modern protective gear returned to fashion, as if in a time warp, in new form.

We find a leveling between folk remedies and modern medicine, as we live collectively in what she calls a “ground-zero moment of empiricism”–if one in which we are deluged by data, but short in knowing what is data, as we are lacking in explanatory models. This is a bit unfair, as we still can profit from autopsies, and have been able to contain spread by hand-washing–but the images of a single magic bullet, or antiviral cure, are far, far away in time. But there is no longer any familiarity with an art of dying, although we found we encountered death with an unforeseen and unpleasant rapidity: we moved from hopes for awaiting immunity or antivirals to a basic need for some consolation of our mortality. There was no possibility of transcendence in a crisis of mortality of dimensions and scope that seem outside the modern era.

And it is ironic that distancing is the best mode to prevent infection–and many deaths may have been enabled by quicker decisions to adopt practices of distancing that could manage viral spread, Trump seemed not to notice that the very globalization he had resisted, and swung against with all his force to win votes, had facilitated the spread of a viral agent whose arrival was denied even as SARS-CoV-2 had already begun to flood the United States, in ways we only mapped in retrospect, as a global village that by March 1 had already grown satellites of viral loads in South Korea, the Middle East, Iran (Teheran), Europe (Milan; Gotheborg), South East Asia, and Hong Kong, as we anticipated its arrival with no health policy in place and no strategy for containing what was already on our shores. The global crossroads defied any choropleth, but we had only mapped the virus for some time in choropleths, as if believing by doing so we could not only map it by national boundaries to keep the virus at bay.

New York Times

But if we lacked a model of infection and communication of COVID-19, we lacked a sense of the geography by which to understand its spread–and to map it–and also, deeply problematically, an inter-agency coordination to assess and respond to the virus’ spread as we sought to contain it: and in the United States, the absence of any coordinating public health agency has left the country in something like free-fall, a cluelessness emblematic by a map cautioning American travelers to take enhanced protections while traveling in Italy or Japan, two major destinations of travel, and avoid all nonessential travel to China, but refrained from ceasing travel plans.

1. The most compelling language of the novel coronavirus is “false positives” and “false negatives,” that seem to betray the unsure nature of standards; the most haunting is the multiple sites COVID-19 can appear in the sites of the body we use to map most disease. While we associate the virus with our respiratory tracts, the virus can do damage to multiple organ systems, as well as create blotchiness of “covid toes” due to burst peripheral blood vessels; it can damage multiple organ systems simultaneously, including the kidneys, heart, lungs, brain, and linger in our intestinal tract where it can flourish and proliferate; the virus can reduce the ability of our blood to form clots, or disable our ability to form clots.  The ACE-2 receptor protein, a launching pad for viral infections, lies in our lungs and respiratory tract but in stomach, intestines, liver, kidneys, and brain. Increased sensitivities among those suffering from high blood pressure, cardiac disease, and diabetes reflect the nosological difficulties of classifying the virus as a cause of death or to grasp it as an illness, let alone to read data about the disease. If the virus lodges in the most delicate structures of the alveoli, which it causes to collapse as it infects their lining, it can take multiple pathways in the body, and as its pathway of infection may be multiple, medical response must be improvised with no playbook for clinical care.

All we know is that our medical staff desperately need protective gear. On top of that, it hardly helps that we are without a clear national policy, and find that the United States government has engaged in far less transparency that one could have ever expected.

We can only say its spread is accelerated dramatically by structures of globalization, and it stands to disrupt them. utterly Even as we map what seem total global knowledge of the disease, analogous to what we have come to expect from Global Positioning System, the multiple holes in our picture of the spread of the disease provide little sense of mastery over the pathways of communication, contraction, and infection we have come to expect from maps. These maps may even be especially disorienting in a world where expertise is often dismissed in the United States–not only by the U.S. President, but out of frustration at the inability to distance, diagnose, track or supervise the disease that is increasingly threatens to get the better hand. Have our visualizations been something of a losing battle, or a war of atrophy we will not win? Or do we even know what sorts of data to look at–indeed, what is information that can help us process a sense of what might be the geography of the contraction or the transmutability of the virus? Is the virus eluding our maps, as we try to make them? These sort of questions of making sense may be the process of science, but they trace, suddenly, a far steepder learning curve than we are used.

A dismissed biomedical researcher who ran efforts to develop a vaccine cautioned that we still lack that the failure a trusted, standard, and centralized plan for testing strategies must play a part in the coordinated plan “to take this nation through this response.” Dr. Bright, who was abruptly removed last month from his position as head of the Biomedical Advanced Research and Development Authority, bemoaned the limited statistics, alas, in large part as fear of providing too many tests–or fanning the flames of insecurity that testing might promote in the general public and in our financial markets, seem to have created the most dangerously deceptive scenario in which the United States seems to be committed to projecting confidence, even if it is the global epicenter of the pandemic.

Have we developed a language to orient ourselves to the scale of emergency in the spread of COVID-19? While we turn to images of natural disasters in describing the “epicenter” of the outbreak in Wuhan, this hardly conjures the species jump and under-the-radar communication of the virus that was not tracked for months before it emerged as a global threat. In tracking COVID-19 globally, or over a broad expanse of nations or states, we often ignored the pathways by which the novel coronavirus is spread in crowded spaces, where the single strand of RNA may hang in droplets that linger in the air, and are looking at the small scale maps to track a microscopic pathogen. But we are increasingly aware the spread of these strands, of the virus SARS-CoV-2, that infect populations along increasingly unequal fault lines that divide our cities, nations, health care systems, and crowding, or access to open space, are all poorly mapped in the choropleths into which we continue to smooth the datasets of infections and hospitalizations. While the problems are posed for national health services in each region, the devastation and danger of overloading public health systems and hospitals outweighs are local manifestations of a global crisis of the likes we have not confronted.

2. And the crowding of such numbers beyond the buffers that began with lead to a visual crowding by which we continue to be overwhelmed–and will have been overwhelmed for some time.

April, COIVID-19Iinfections Globally by Country/Clustrmaps May 12, 20202020

For although the global pandemic will clearly be with us for a long time, spatial narratives might be more likely to emerge in networks and in forms of vulnerability, in ways that might reveal a more pronounced set of narratives for how we can respond to a virus than the deep blues of even the limited and constrained datasets that we have, as we struggle against the blindness we have in containment and mitigation, and the frustration of the lack of anything like a vaccine. (This pandemic is almost a metastasis of the anti-vaxxers: confirmation that a vaccine cannot check a disease, it gives rise to concerns that vaccinations might have left us immunologically more vulnerable to its spread . . .and a sense that the hope of eradicating COVID-19 by the availability of a vaccination in four to five years will be widely resisted by anti-vaxxers and their acolytes, to whom the pandemic has given so much new steam. Yet as the virus interacts with the viral posting of anti-vaxxers resisting social distancing or collective policies of response, the stresses that exist in our society will only be amplified.) And if as late as February 24, only three laboratories in the United States did test for COVID-19–artificially lowering public numbers–even confirmed numbers through March and April were as a result tragically low. Could maps even help to track the disease without a testing apparatus in place?

Global Covid Infections/Datascraped by Avi Schiffman, May 11, 2020

The prestige of the data visualization has been a basis for reopening the nation. Yet if less than a tenth of the world’s population has yet to be exposed to the disease–and perhaps only 5% of the American population, in one estimate, if not lower–the virus is bound to be endemic to the global landscape for quite a considerable length of time. At the same time, one must wonder if the many fault lines that have created such peaks and valleys in the virus’ spread, if confirming its highly infectious nature, to be sure, are not removed from us in some degree by the smooth surfaces of the screens on which we watch and monitor, breath bated, with some terror, its spread, unsure of the accuracy or completeness of the data on which they are based but attentive to whatever they reveal. In many ways, these maps have created an even more precarious relation to the screen, and to the hopes that we find some sign of hope within their spread, or hope to grasp the ungraspable nature of COVID-19.

These datamaps suggest a purchase on a disease we don’t understand, and we don’t even have good numbers on contraction. Yet we are discussing “reopening” the United States, while we do not have anything approaching a vaccine, let alone the multiple vaccines that medical authorities desire before resuming social contact at pre-pandemic levels. How to process the data that we have, and how to view the maps not only by hovering, zooming in, or distancing the growing rates of infection, but tracking the virus in spaces, mapping levels of infection against adequacy of testing, mortalities against comorbidities, against with the chronic nature of the virus must be understood, as well as levels of hospitalization levels; and distinctions or mutations of the virus and against age ranges of afflicted–by, in other words, drilling beneath the datasets to make our maps’ smooth surfaces more legible, as horrifying as they are?

Can we use what we have to pose problems about the new nature of this contagion we don’t fully understand, but has been mapped in ways that seek to staunch fears of a decline in the stock market, as much as an emergency of public health, with up to one third of the population at risk of infection? The instinctive reaction of the Trump Health and Human Services to create public-private “community testing sites” for drive-thru or drive-up testing at Walgreens, CVS, Rite Aid, Kroger and other pharmacies seems reflexive for a government wanting to minimize federal overhead, but a far less exact means, and a far less intuitively sensible basis to attract potentially infected individuals to sites of public congregation. The hope of Verily–a subsidiary of Alphabet, whose Project Baseline boasts the slogan, “We’ve Mapped the World, Now Let’s Map Human Health,” in a bizarrely boosterish rhetoric, aggregates medical for medical screening in California–

Select States for Project Baseline Testing/Verily

–and select states–was the primary response that Trump had promised of a network of drive-up testing sites that has never materialized, even as it expanded to a hundred sites in thirty states. After Walmart opened two sites, and Walmart 40, the difficult accuracy of creating multiple testing sites was prohibitive, the testing sites that were rolled out with the assistance of private entrepreneurs that Jared Kushner enlisted, that filled the absence of any coherent public health response–perhaps, terrifyingly, in concert with his brother’s health care company, Oscar, which also partnered with CVS and some of the same pharmaceutical services, focussing on drive-thru sites more than sustained medical care, focussing largely on calming retailers who feared the arrival of infected patients on their parking lots, more than on the efficacy of testing, which they didn’t understand. If only 40% of promised test kits were made available, the absence of providing staffers or selling, as in Massachusetts, self-testing kits–and failing to provide many in large cities like New Orleans, as if to keep the final tally of infected artificially low. Even if the Center for Disease Controls had never done clinical tests on hydrochloroquine, whose dangers on humans were not studied, and despite some benefits of the antiviral on cell cultures, none appeared in mice, the drug was promoted widely on social media as late as April, although its mention on Twitter grew, even as the government delayed any roll-out of testing sites.

The demand to calm the nation, a position dangerously close to concealment, delayed action on a wave of infection that President Trump had long sought to deny, claim to be overblown, or call Fake News. The lack of a public testing initiative, and rejection of the tests of other nations, forced the United States to adopt a disorganized go-it-aloneist approach, akin to isolationism, not benefiting from the potential ties to Chinese doctors’ response, or the testing kits that would have been available that the World Health Organization (WHO) had suspected since January, and made test kits for poorer countries that might be replicated in the United States–which chose to make its own tests to ensure the highest quality. When WHO had urged countries “test, test, test” for the coronavirus to contain its spread, the global health organization provided 1.5 million tests to 120 countries who lacked the ability to test by March 16; the United States went without the diagnostic tests developed in Berlin by la CharitĂ©, implemented in Germany. If the United States had submitted a test to WHO as well, the German test the health organization adopted was never used or ordered–and by mid-March processed a sixth the specimens as in Italy, with found over six times as many cases, and an eleventh as in South Korea, which found double the cases.

By April, the picture had improved, but not much.

And based on later data of the virus that spread to other American cities, the virus that had infected so many in New York seems to have spread to other American metropoles by May, as we were still awaiting broad testing.

The Built World

Walking the streets in my now apparently abandoned neighborhood for an errand after a few weeks of sheltering in place in Oakland, I had the eery experience of navigating and inhabiting empty city. While I knew the pavement, I almost felt no longer familiar with the streets that afternoon. There was the sense that no one knew the state of affairs about reopening, and many were just puzzled about how to proceed: as a few young kids skateboarded up Shattuck Avenue, profiting from the lack of cars, some odd improvised bicyclists were on the sidewalk. The absence of interaction was a weird pause indeed, giving an eery sense of the timelessness of space, as if the time/space fabric by which I had long seen the neighborhood was suddenly out of whack. While no visible destruction had happened or occurred, the disembodied nature of the inhabited world was drained, even as it was filled with sunlight and birds, giving me the eery sense I had had when I looked at the machine-read maps of building footprints, “Every Building in the United States,” whose section situating Bay Area buildings hung on our refrigerator wall, like a scary map of the archeological ruins of a future Baedecker Guide to the ruins of San Francsico.

Had the designers of te interactive webmap of machine-readable imagery Microsoft had assembled intended the eery effect of describing the inhabited world as a ghostly ruin of lived life? The relegation to place-names to a very secondary status in the image of the overbuilt landscape seems to lie on the edges of the black blocks of built space that is was the basis for the AI map distilled from aerial photographs, and parsed as black and white data. If its form seems oddly ghostly, the reduction of the monochrome paper map reveals shades of grey that fade into rare open spaces, where one’s visual attention seems at first drawn, before one returns, with hopes for some sense of recognition, to the built spaces that one knows, and the congestion of black that marks urban agglomerations. The black boxes of settlement reveals the crowding of our coasts, the density of much urban housing and indeed of the area of the East Bay where I live, but is also an eerily image of an inhabited landscape selectively organized to omit any sign of living presence–either of “wilderness” or habitat, but anthropocentrically maps the anthropogenic world as if for posterity. For is not the black boxes of building footprints something like a record of the anthropogenic imprint on the world, by now extended across the globe. The building footprint map derived from AI is a rewriting of the ancient notion of the ecumene–the “habitable” more than “inhabited world”–or οἰκουμένη, which sought to encapsulate the inhabited regions as the ones that entered human comprehension: is it a removal of the humanist object of the map, now mediated through machine learning?

If the ancient geographers discussed the οἰκουμένη as the “habitable world” from the frozen north to the scalding sub-equatorial lands that seemed to “balance” the inhabited regions, as if what merited human attention and contemplation was that region that permitted settlement: the turn to a record of imperial administration in the Roman Empire–and of religious unity in a ‘civilized’ world–introduced the governmentality of the control over the inhabited world, that by the Renaissance had become an enticing image of national incorporation and political ties, that became intellectually articulated in the post-Cold War as a global ecumene of imperial cultural dominance and integration incarnated in European inheritance of political institutions, science, technology, and economic forms as a world system: the association of a global integration whose exponent in historical texts was perhaps William McNeill’s Rise of the West (1963) had withered away by the time of the data-driven map of inhabitation, as we have become increasingly aware of mapping the human impact on the world–an image in which the building footprint map might be placed.

It is hard to discuss intentions in a map that was organized by AI, but the ledger size newsprint that covered almost a full side of the refrigerator, hanging on magnets, assembled a flyover of the ruins of a future world, a snapshot of each and every building in the area. The result is a poor excuse for a “wall-map” of the region of Northern California. It seems more of a memento mori of the prosperity Silicon Valley once enjoyed from a future world, registering the intense economic growth that fueled the housing bubble along the San Francisco Bay, in an unintentional snapshot of the explosion of paved space and housing across the coastal margins of what was once one of the more “edgy” areas of the United States: entertaining the imagined future might have created the perverse pleasure of hanging it in my kitchen, long before COVID-19 struck, a celebratory if slightly morose record of the world in which we once lived.

But the sidewalks were empty and sun intense; storefronts often boarded up. The streets were no longer places for salutation or recognition, even if I greeted a familiar mailman on my way home: as if no time for social niceties remained I walked down the sidewalks and into empty streets, rarely negotiating margins of safety, or distancing with a few folks on foot, noticing with a cringe the large number of homeless who stood out against the stark streets, closed storefronts, and empty stores.

They were, as it were, always there. I had been cutting myself off from the surroundings, as I never thought I would. As I had been sheltering, thoughts going global as I was following updates about the pandemic, this was a stone’s through from my home, so many had none. Looking down Adeline Street, at the still tents of homeless encampments that may have multiplied, I felt new distance gaping between us, as the very streets I had walked down regularly seemed to have been forgotten while sheltering indoors, the stores now empty, their windows recently boarded, few driving in the streets where one might walk without danger. The eery absence of population was a scene from The Last Man, momentarily interrupted by an isolated airplane, the first seen in days, flew overhead: I felt like I was on a filmset, more than where I lived, a tracing of life past.

If we were sheltering, what was place, anyways?, I wondered with the footprint map in mind. Empty streets looked like nothing more than an apocalyptic reimagining of the neighborhood, drained of inhabitants, save the apparently increasing cluster of homeless tents, looking far more embattled, and more survivalist than ever. If the building footprint map was restricted to spaces where people lived and work, the ghostly anthropogenic substrate seemed to have an eery counterpart in the homeless encampments near my house. The survivalism was evident in the homeless settlement that had in recent years overflowed, expanding to fill in the island of trees where how Steve Gillman’s 2011 public sculpture marked the interurban divide. The public sculpture elegantly if snidely punned on the allegedly dismissive pity saying ascribed to an icon of modernity about her native home–“There’s no There there“–as an entertainment for motorists, or BART passengers, as much as a public art for pedestrian passersby–by broadcasting a literary reference in greenery.

The two words marked the Oakland-Berkeley border by two words, now rusted fifteen years later, as relics of an earlier epoch themselves: the homeless encampment blurred both sides of the dividing line between the cities which had long since melded indistinguishably in the increasingly gentrifying area where I had lived for twenty-odd years.

The erasure of a sense of “here” that was promoted by the public sculpture seemed erased in the AI map, that reduced space to built houses, even as the homeless were the only residents in sight as I walked around the tensely empty neighborhood. I’d long appreciated, if a bit begrudgingly, how the Gateway_Project defined the edge of Berkeley CA took Gertrude Stein’s saying and liberalized it in hight-foot tall powder-coated steel letters, where the BART tracks go underground, intended as “a literary and whimsical welcoming to Berkeley,” where they supposedly read not only Stein’s poetry, but where so many poets had lived–and was a “here” worth commemorating by sculptured letters, a new Fons et origo of the Beat Generation, perhaps, or a dynasty of mid-twentieth century poets–Kenneth Rexroth; Czeslaw Milosz; Allen Ginsberg; Gary Snyder; Frank Whalen; Thom Gunn; Robert Hass–by 2002 recognized as a literary patrimony. Designed primarily for passing motorists, as if few could be imagined to walk nearby, the site built to commemorate a “sense of place” had become a cluster of encampments, as if that was the only place that existed at a time when all remained shuttered indoors–if in 2010, just ten years ago, one letter was covered, by a group of Oakland knitters, to transform it to “HERE/HERE,” peacefully protesting the work as barely concealing an agenda of gentrification.

Jill Posener, on Jill Rants and Raves/June 1, 2010

The collective of knitters who had covered the “T” as if to object to the tired trope with which Oakland was long saddled was the result of a. relatively calm tussle, cast as a border war against gentrification. But the global pandemic had subsumed any distinction of “here” and “there” in a new global: the AI map seemed to be indeed a snapshot of the scale of habitation before the pandemic, a ghostly picture of an earlier time.

As I walked through it, at least, the same North Oakland neighborhood was suddenly, if maybe temporary, rendered ghostly: the built landscape that I was inhabiting was the same world, with fewer inhabitants, and less secure attachment to palce–as if the artificial interruption of indoors life shifted my relation to built space, made it harder to navigate, and shifted the security of place, and indeed removed any sense of recognizability from the built landscape, almost to ask what the civilization was that led to the building of all this paved space.

The unmooring from physical presence was like being dropped, I imagined in a flight of fantasy, to that Microsoft map, so akin as a snapshot to the sort of map of archeological ruins future generations might trace as guidelines of orientation to a lost past, when what was the greatest “here” of antiquity–the city of Rome–was etched by nineteenth century archeologists and antiquarians by the physical plant of what once stood on the site of the ancient Roman forum, only perceptible to the eyes of tourists if they had trained themselves on the map to imagine the ghost-like presence of architectural monuments that had once affirmed the place of Rome at the center of the world at a far earlier time.

Where was here, now, on the AI map? Was the tie I was drawing between the map and the uninhabited neighborhood only the depressive meanderings of a middle-aged crisis? Or was it a global one? West Berkeley and North Oakland had been certainly rendered quite a different place, quite suddenly, and not a comfortable one–still inhabited by ghosts. Stripped of my points of reference or familiarity with my neighborhood, a few dispossessed in the sidewalks, of what wasn’t a nice area of town, I was reminded rather urgently of ongoing part of urban life no longer framed by sounds of traffic, public transport, open businesses and pedestrian sounds, that continued while I was indoors. The degree zero of urban life reminded me of the empty landscape of building footprints that, in a detailed satellite overview that recalled nothing more than the outline of an archeological dig of ancient city, as if drained of motion, and filled with apprehension, in a damn eery way. Was this a pause or a new landscape?

I had only recently been navigating the 2018 building footprint map, “Every Building in the United States,” and aout a year ago, hung the section of the houses of the Bay Area onto our refrigerator wall. The creation of Microsoft that was removed as one might imagine from the ancient notion of an “inhabited world,” comprised of building outlines, a distanced description of the world a declination of mapping human settlements, mediated through what seemed the iconography of an archeological map of a removed time, rather than the actual lay of the land–or, better yet, it seemed to exist in two planes more than ever, and both as a historical record of a snapshot of built space across America, and of actuality. The interactive website of the machine-readable result of aerial imagery that invites one to zoom closely not on landscapes, but a black and white rendering of built space, recalled nothing more than a flyover of the ruins of a future world.

The aerial snapshot of each and every building in its current position had a sci-fi aspect of a record of space drained of nature, biodiversity, non-anthropogenic environments, and life–distilling selectively the extent of built spaces across an otherwise quiet and otherwise uninhabited world: as if the perfect document of the anthropocene, this was the built landscape, removed from and detached from a natural world. This was the built landscape of the region, divorced from the lay of the land, as if a perfection of the GPS contents of street view, without any street traffic or greenspace at all. The stark interactive map of 2018 seemed to be newly present to the space I was negotiating in my mind, even more stripped to its bare bones and evacuate of inhabitants.

The vertiginously uninhabited interactive map peered at onscreen allowed one to look at the nation and soon to whatever spot on the map, suddenly panning and focussing into crisp detail, but lacking all sign of inhabitants, save the names on each street or place. The sense of exploring a neighborhood I once knew may have been an accelerated arrival in late middle age. But the spatially empty landscape of building footprints encountered I opened in 2018, “Map of Every Building in the United States,”was filled with a sense of dread and of testing my own geographical knowledge, scanning to familiar neighborhoods and structure, and matching abilities to recognize the flattened forms against the material structures with which they correlate.  There is no sense of the amount of chemical waste and diesel pollutants in the nation’s largest port, Long Beach, pictured in the header to this post, where pollution has caused ongoing health problem for residents.
