Voids and Vacuums

[Image: Google Maps view of Mosul Dam (bottom center) and the huge reservoir it creates].

Dexter Filkins—author of, among other things, The Forever War—has a long new piece in the first 2017 issue of The New Yorker about the impending collapse of Iraq’s Mosul Dam.

The scale of the potential disaster is mind-boggling.

If the dam ruptured, it would likely cause a catastrophe of Biblical proportions, loosing a wave as high as a hundred feet that would roll down the Tigris, swallowing everything in its path for more than a hundred miles. Large parts of Mosul would be submerged in less than three hours. Along the riverbanks, towns and cities containing the heart of Iraq’s population would be flooded; in four days, a wave as high as sixteen feet would crash into Baghdad, a city of six million people. “If there is a breach in the dam, there will be no warning,” Alwash said. “It’s a nuclear bomb with an unpredictable fuse.”

Indeed, “hundreds of thousands of people could be killed,” according to a UN report cited by Filkins.

What’s interesting from a technical perspective is why the dam is so likely to collapse. It’s a question of foundations. The dam was built, Filkins writes, on rock “interspersed with gypsum—which dissolves in contact with water. Dams built on this kind of rock are subject to a phenomenon called karstification, in which the foundation becomes shot through with voids and vacuums.”

Filling those voids with grout is now a constant job, requiring dam engineers to pump huge amounts of cementitious slurry down into the porous rock in order to replace the dissolved gypsum.

At one point, Filkins goes inside the dam where “engineers are engaged in what amounts to an endless struggle against nature. Using antiquated pumps as large as truck engines, they drive enormous quantities of liquid cement into the earth. Since the dam opened, in 1984, engineers working in the gallery have pumped close to a hundred thousand tons of grout—an average of ten tons a day—into the voids below.”

Finding and caulking these voids, Filkins writes, is “deeply inexact.” They are deep underground and remain unseen; they have to be inferred. The resulting process is both absurd and never-ending.

The engineers operating [the grout pumps] can’t see the voids they are filling and have no way of discerning their size or shape. A given void might be as big as a closet, or a car, or a house. It could be a single spacious cavity, requiring mounds of grout, or it could be an octopus-like tangle, with winding sub-caverns, or a hairline fracture. “We feel our way through,” [deputy director Hussein al-Jabouri] said, standing by the pump. Generally, smaller cavities require thinner grout, so Jabouri started with a milky solution and increased its thickness as the void took more. Finally, after several hours, he stopped; his intuition, aided by the pressure gauges, told him that the cavity was full. “It’s a crapshoot,” [civil engineer Azzam Alwash] told me. “There’s no X-ray vision. You stop grouting when you can’t put any more grout in a hole. It doesn’t mean the hole is gone.”

It’s hard not to think of a scene in Georges Perec’s novel Life: A User’s Manual, a scene I have written about before. There, a character named Emilio Grifalconi picks up an old, used table only to find that the support column at its center is “completely worm-eaten.” Slowly, painstakingly, operating by intuition, he fills the worm-eaten passages with a permanent adhesive, “injecting them with an almost liquid mixture of lead, alum and asbestos fiber.”

The table collapses anyway, alas, giving Grifalconi an idea: “dissolving what was left of the original wood” in order to “disclose the fabulous arborescence within, this exact record of the worms’ life inside the wooden mass: a static, mineral accumulation of all the movements that had constituted their blind existence, their undeviating single-mindedness, their obstinate itineraries; the faithful materialization of all they had eaten and digested as they forced from their dense surroundings the invisible elements needed for their survival, the explicit, visible, immeasurably disturbing image of the endless progressions that had reduced the hardest of woods to an impalpable network of crumbling galleries.”

Whether or not such a rhizomatic tangle of grout-filled chambers, linked “voids and vacuums” like subterranean grapes, could ever be uncovered and explored beneath the future ruins of a safely dismantled Mosul Dam is something I will leave for engineers.

However, Filkins points out one possible solution that would sidestep all of this: this option, he writes, “which has lately gained currency, is to erect a ‘permanent’ seal of the existing dam wall—a mile-long concrete curtain dropped eight hundred feet into the earth.”

This would not be the only huge subterranean wall to be proposed recently: think of the “giant ice wall” under construction beneath the Fukushima nuclear power plant in Japan: “Japan is about to switch on a huge refrigeration system that will create a 1.5-km-long, underground frozen ‘wall,’ in hopes of containing the radioactive water that’s spilling out of the Fukushima nuclear power plant, which went into meltdown following the earthquake and tsunami of March 2011.”

The Soft Spot

geoborder[Image: Close-up of the 2010 State Geologic Map of California].

An interesting story published last month in the L.A. Times explored the so-called “sweet spot” for digging tunnels along the California/Mexico border.

“Go too far west,” reporter Jason Song explained, “and the ground will be sandy and potentially soggy from the water of the Pacific Ocean. That could lead to flooding, which wouldn’t be good for the drug business. Too far east and you’ll hit a dead end of hard mountain rock.”

However, Song continues, “in a strip of land that runs between roughly the Tijuana airport and the Otay Mesa neighborhood in San Diego, there’s a sweet spot of sandstone and volcanic ash that isn’t as damp as the oceanic earth and not as unyielding as stone.”

More accurately speaking, then, it is less a sweet spot than it is a soft one, a location of potential porosity where two nations await subterranean connection. It is all a question of geology, in other words—or the drug tunnel as landscape design operation.

border[Image: Nogales/Nogales, via Google Maps].

With the very obvious caveat that this next article is set along the Arizona/Mexico border, and not in the San Diego neighborhood of Otay Mesa, it is nonetheless worth drawing attention back to an interesting article by Adam Higginbotham, written in 2012 for Bloomberg, called “The Narco Tunnels of Nogales.”

There, Higginbotham describes a world of abandoned hotel rooms in Mexico linked, by tunnel, to parking spots in the United States; of streets subsiding into otherwise unknown narco-excavations running beneath; and of an entire apartment building on the U.S. side of the border whose strategic value is only revealed later once drug tunnels begin to converge in the ground beneath it.

Here, too, though, Higginbotham also refers to “a peculiar alignment of geography and geology,” noting that the ground conditions themselves are particularly amenable to the production of cross-border subterranea.

However, the article also suggests that “the shared infrastructure of a city”—that is, Nogales, Arizona, and its international counterpart, Nogales, Mexico—already, in a sense, implies this sort of otherwise illicit connectivity. It is literally built into the fabric of each metropolis:

When the monsoons begin each summer, the rain that falls on Mexico is funneled downhill, gathering speed and force as it reaches the U.S. In the 1930s, in an attempt to control the torrent of water, U.S. engineers converted the natural arroyos in Nogales into a pair of culverts that now lie beneath two of the city’s main downtown streets, Morley Avenue and Grand Avenue. Beginning in Mexico, and running beneath the border before emerging a mile into the U.S., the huge tunnels—large enough to drive a car through—created an underground link between the two cities, and access to a network of subterranean passages beneath both that has never been fully mapped.

This rhizomatic tangle of pipes, tubes, and tunnels—only some of which are official parts of the region’s hydrological infrastructure—results in surreal events of opportunistic spelunking whereby “kids would materialize suddenly from the drainage grates,” or “you would see a sewer plate come up in the middle of the street, and five people would come up and run.”

Briefly, I’m reminded of a great anecdote from Jon Calame’s and Esther Charlesworth’s book Divided Cities, where the split metropolis of Nicosia, Cyprus, is revealed to be connected from below, served by a shared sewage plant “where all the sewage from both sides of the city is treated.” The authors interview the a local waste manager, who jokes that “the city is divided above ground but unified below.”

In any case, the full article is worth a read, but a tactical geological map revealing sites of likely future tunneling would be a genuinely fascinating artifact to see. I have to assume that ICE or Homeland Securitylet alone the cartels—already have such a thing.

An exceptional, extreme, and largely unexplored place

gunnison
The always interesting Center for Land Use Interpretation is seeking proposals from artists, writers, designers, architects, and more to “explore the land and waterscape of the north arm of the Great Salt Lake, known as Gunnison Bay.”

It’s a landscape they describe as “an exceptional, extreme, and largely unexplored place”:

The construction of a filled-in railroad causeway in the late 1950s cut the original lake in half, creating a new, anthropogenic entity, more isolated and saline, that has evolved into a landscape of desiccation that resembles another planet, or this one in some past or future time.

They specifically hope that you’ll include in your exploration of this seemingly parallel terrestriality the so-called Great Salt Lake Exploration Platform, or GSLEP, a pontoon structure built by Chris Taylor and Steve Badgett (it’s a boat).

Proposals are due March 1, 2016.

There is much more information over at CLUI’s website, so check out the full call-for-proposals.

The Dam Industry’s Chernobyl

There’s an alarming new piece up at The New Yorker looking at two potential dam failures, in Iraq and Zambia, and the extraordinary effects these disasters would have. The collapse of Iraq’s Mosul Dam, for example, which the U.S. Army Corps of Engineers calls “the most dangerous dam in the world,” “could drown as many as five hundred thousand people downstream and leave a million homeless.” The collapse of Zambia’s Kariba Dam, meanwhile, and the resulting megaflood would be “the dam industry’s Chernobyl”: “three million people live in the flood’s path; most would die or lose their crops or possessions. About forty per cent of the electricity-generating capacity of twelve southern African nations would be eliminated.” (Spotted via @waltonwater)

Water & Power

While going through a bunch of old photos of Los Angeles on the Library of Congress website for a project I’m doing at USC this year, I was amazed by these interior shots of the F. E. Weymouth Filtration Plant at 700 North Moreno Avenue in L.A.

Despite being designed for the administration of an urban water-processing site, the interiors seem to play with some strange, Blade Runner-like variation on Byzantine modernism, where federalist detailing meets a hydrological Babylon.

[Image: Via the Library of Congress].

As the open plan interior of a contemporary home, this place would almost undoubtedly show up on every design website today—imagine a better railing on the central staircase, a galley kitchen on one side, a bed lit by retro-styled fluorescent tubes at the far end, some bold moments of color—but it’s just a piece of everyday municipal infrastructure.

[Image: Via the Library of Congress].

In any case, continuing the vaguely sci-fi feel, there is even a tiled fountain—a Mediterranean concession to the building’s role in water filtration—on one wall, emphasized by these amazing lighting features, yet it looks more like a film set, both ancient and futuristic.

[Image: Via the Library of Congress].

Alas, I’m not a huge fan of the exterior, although it is, in fact, a fairly amazing example of municipal design gone more sacred than profane. But an equally streamlined modernism in keeping with those interiors would have made this place totally otherworldly.

Finally, the marbled lobbies continue the surreal mix-up of styles, eras, and materials with something that could perhaps be described as Aztec corporatism with its huge graphic seal and other geometric motifs.

Abandoned Basements as Stormwater Basins

[Image: Rendering of a possible “BaseTern” landscape by students Brett Harris, Andrew D’Arcy, and Heidi Petersen, via Landscape Architecture Magazine].

Not all the news coming out of Milwaukee involves misguided highway megaprojects or tax-funded crony capitalism—though there is that.

For example, Wisconsin governor Scott Walker—confusing an earlier generation’s urban mistakes with how a city is meant to function—has been plowing billions of dollars’ worth of taxpayer money into “freeway megaprojects” for which “the pricetag got so big that leaders from his own party rejected his plan as fiscally irresponsible, leaving the state budget in limbo,” Politico reports:

As the state has shifted resources into freeway megaprojects, 71 percent of [Wisconsin’s] roads are in mediocre or poor condition, according to federal data. Fourteen percent of its bridges are structurally deficient or functionally obsolete, which is actually better than the national average. Walker and his fellow Republicans have killed plans for light rail, commuter rail, high-speed rail, and dedicated bus lanes on major highways, so there is almost no public transportation connecting Milwaukee to its suburbs, intensifying divisions in one of the nation’s most racially, economically and politically segregated metropolitan areas. Yet Walker, who is running for president as a staunch fiscal conservative, has pushed a $250 million-per-mile plan to widen Interstate 94 between the Marquette and the Zoo despite fierce local opposition.

If that sounds both avoidable and unfortunate, consider the fact that “Walker also killed a ‘Complete Streets’ program that pushed road builders to accommodate bicyclists and pedestrians.”

[Images: (top) Milwaukee’s Marquette interchange, nearly the same size as the city it cuts through; (bottom) Milwaukee before the interchange. Images via Politico].

At the same time, Walker has also “championed a high-profile proposal to spend a quarter of a billion dollars of taxpayer money to help finance a new Milwaukee Bucks arena—all while pushing to slash roughly the same amount from state funding for higher education,” the International Business Times reports.

But, hey, why does Wisconsin need universities when everyone can just go to an NBA game? Not that benefitting the public is even Walker’s goal: “One of those who stands to benefit from the controversial initiative is a longtime Walker donor and Republican financier who has just been appointed by the governor to head his presidential fundraising operation.”

In any case, an interesting landscape test-project is currently underway in Milwaukee, called the “BaseTern” program.

As the city explains it, a “BaseTern” is “an underground stormwater management or rainwater harvesting structure created from the former basement of an abandoned home that has been slated for demolition.” Why is the city doing this?

By using abandoned basements, the City saves the cost of demolition on these structures (filing the basement and grading the surface) and on excavation for the new structure. In addition, BaseTerns provide significant stormwater storage capacity on a single site, the equivalent of up to 600 rain barrels.

The result, the city is keen to add, is “not an open pit. Rather a BaseTern is a covered structure, which is covered with topsoil and grass, and will appear the same as conventional vacant lot.”

In their July 2015 issue, Landscape Architecture Magazine explained that this is, in fact, “the world’s first such system.” Conceived—and actually trademarked—by a city official named Erick Shambarger, the idea was inspired by a GIS-fueled discovery that the worst flooding in the city always “occurred in neighborhoods with high rates of foreclosures. The city controls roughly 900 foreclosed properties, many of which it plans to demolish. Shambarger figured the city could preserve the basement structure and put it to use.”

[Images: Two BaseTern design diagrams, taken from Milwaukee’s “Vacant Basements for Stormwater Management Feasibility Study“].

While there is something metaphorically unsettling in the idea that parts of a blighted, financially underwater neighborhood might soon literally be underwater—transformed into a kind of urban sponge for the rest of Milwaukee—the notion that the city can discover in its own economic misfortune a possible new engineering approach for dealing with seasonal flooding and super-storms is an inspiring thing to see.

The BaseTern program also potentially suggests a stopgap measure for coastal cities set to face rising sea levels well within the lifetimes of the coming generation.

In the all but inevitable managed retreat from the coast that seems set to kick off both en masse and in earnest by midcentury—something that is already happening in New York City, post-Sandy—perhaps the subterranean ruins of old neighborhoods left behind can be temporarily repurposed as minor additions to a broader coastal program intent on reducing flooding for residents further inland.

Before, of course, those underground voids—former guest bedrooms, dens, man caves, she sheds, and basements—are inundated for good.

Joyful Rendezvous Upon Pure Ice and Snow

[Image: Snow-making equipment via Wikipedia].

The 2022 Winter Olympics in Beijing are something of a moonshot moment for artificial snow-making technology: the winter games will be held “in a place with no snow.” That’s right: “the 2022 Olympics will rely entirely on artificial snow.”

As a report released by the International Olympic Committee admits, “The Zhangjiakou and Yanqing Zones have minimal annual snowfall and for the Games would rely completely on artificial snow. There would be no opportunity to haul snow from higher elevations for contingency maintenance to the racecourses so a contingency plan would rely on stockpiled man-made snow.”

This gives new meaning to the word snowbank: a stock-piled reserve of artificial landscape effects, an archive of on-demand, readymade topography.

Beijing’s slogan for their Olympic bid? “Joyful Rendezvous upon Pure Ice and Snow.”

[Image: Snow-making equipment via Wikipedia].

Purely in terms of energy infrastructure and freshwater demand—most of the water will be pumped in from existing reservoirs—the 2022 winter games will seemingly be unparalleled in terms of their sheer unsustainability. Even the IOC sees this; from their report:

The Commission considers Beijing 2022 has underestimated the amount of water that would be needed for snowmaking for the Games but believes adequate water for Games needs could be supplied.

In addition, the Commission is of the opinion that Beijing 2022 has overestimated the ability to recapture water used for snowmaking. These factors should be carefully considered in determining the legacy plans for snow venues.

Knowing all this, then, why not be truly radical—why not host the winter games in Florida’s forthcoming “snowball fight arena,” part of “a $309 million resort near Kissimmee that would include 14-story ski and snowboard mountain, an indoor/outdoor skateboard park and a snowball fight arena”?

Why not host them in Manaus?

Interestingly, the IOC also raises the question of the Games’ aesthetics, warning that the venues might not really look like winter.

“Due to the lack of natural snow,” we read, “the ‘look’ of the venue may not be aesthetically pleasing either side of the ski run. However, assuming sufficient snow has been made or stockpiled and that the temperature remains cold, this should not impact the sport during the Games.”

Elsewhere: “There could be no snow outside of the racecourse, especially in Yanqing, impacting the visual perception of the snow sports setting.” This basically means that there will be lots of bare ground, rocks, and gravel lining the virginal white strips of these future ski runs.

[Image: Ski jumping in summer at Chicago’s Soldier Field (1954); via Pruned].

Several years ago, Pruned satirically offered Chicago as a venue for the world’s “first wholly urban Winter Olympics.” With admirable detail, he went into many of the specifics for how Chicago might pull it off, but he also points out the potential aesthetic disorientation presented by seeing winter sports in a non-idyllic landscape setting.

“Chicago’s gritty landscape shouldn’t be much of a handicap,” he suggests. Chicago might not “embody a certain sort of nature—rustic mountains, pastoral evergreen forests, a lonely goatherd, etc.,” but the embedded landscape technology of the Winter Games should have left behind that antiquated Romanticism long ago.

As Pruned asks, “have the more traditional Winter Olympic sites not been over the years transformed into high-tech event landscapes, carefully managed and augmented with artificial snow and heavy plows that sculpt the slopes to a pre-programmed set of topographical parameters?”

Seen this way, Beijing’s snowless winter games are just an unsustainable historical trajectory taken to its most obvious next step.

[Image: Making snow for It’s A Wonderful Life, via vintage everyday].

In any case, the 2022 Winter Olympics are shaping up to be something like an Apollo Program for fake snow, an industry that, over the next seven years, seems poised to experience a surge of innovation as the unveiling of this most artificial of Olympic landscapes approaches.

Lost Lakes of the Empire State Building

[Image: Sunfish Pond].

Something I’ve meant to post about for awhile—and that isn’t news at all—is the fact that there is a lost lake in the basement of the Empire State Building. Or a pond, more accurately speaking.

After following a series of links leading off from Steve Duncan’s ongoing exploration of New York’s “lost streams, kills, rivers, brooks, ponds, lakes, burns, brakes, and springs,” I found the fascinating story of Sunfish Pond, a “lovely little body of water” at the corner of what is now 31st Street and Fourth Avenue. “The pond was fed both by springs and by a brook which also carried its overflow down to the East River at Kip’s Bay.”

Interestingly, although the pond proper would miss the foundations of the Empire State Building, its feeder streams nonetheless pose a flood risk to the building: the now-buried waterway “leading from Sunfish Pond still floods the deep basement of the Empire State Building today.”

To a certain extent, this reminds me of a line from the recent book Alphaville: “Heat lightning cackles above the Brooklyn skyline and her message is clear: ‘You may have it paved over, but it’s still a swamp.'” That is, the city can’t escape its hydrology.

But perhaps this makes the Empire State Building as good a place as any for us to test out the possibility of fishing in the basements of Manhattan: break in, air-hammer some holes through the concrete, bust out fishing rods, and spend the night hauling inexplicable marine life out of the deep and gurgling darkness below.

Drylands Design

If I could go back in time, there are two things I would have prioritized this autumn, had I known about them earlier: 1) I would have stopped by the Out of Water: Innovative Technologies in Arid Climates exhibition, curated by Liat Margolis and Aziza Chouani, at the Arid Lands Institute of Woodbury University, and 2) I would have attended more of the accompanying lecture series. The whole thing sounds amazing.

Here’s a description of the lecture series:

Excavating Innovation: The History and Future of Drylands Design examines the role of water engineering in shaping public space and city form, by using arid and semi-arid sites in India, the Middle East, the Mediterranean, and the New World to explore how dryland water systems throughout history have formed and been formed by ritual, hygiene, gender, technology, governance, markets, and, perhaps above all, power.

The series “brings together historians, urbanists, and contemporary designers to selectively excavate global historical case studies and reveal relevance to contemporary design practice.”

The specific lectures sound almost too good to be true, including a forthcoming talk this Thursday, November 18, about the stepwells of India—fantastically gorgeous native hydrological structures I’ve returned to again and again in my own off-blog reading and research.

[Image: Stepwell at Chand Baori, courtesy of Wikipedia].

The series continues into 2011 with a lecture by Nan Ellin called “Canalscape: Ancient and Contemporary Infrastructures of Phoenix” (January 27) and one by Vinayak Bharne called “Indigenous Infrastructure and the Urban Water Crisis: Perspectives from Asia” (February 10).

Anyone interested in the idea of “drylands design” or arid-climate technologies should strongly consider picking up a copy of Fred Pearce’s excellent book When the Rivers Run Dry: Water, The Defining Crisis of the Twenty-first Century. In it, Pearce presents a huge variety of vernacular water-harvesting and storage architectures, from Chinese domestic cisterns and dew ponds in the English South Downs to fog-catching nets in Pacific South America. Two other quick suggestions, if you want to extend your reading, include Marc Reisner’s classic Cadillac Desert: The American West and Its Disappearing Water—an immensely interesting but often historically over-detailed book—and James Powell’s Dead Pool: Lake Powell, Global Warming, and the Future of Water in the West. The latter title I favorably reviewed a while back for the The Wilson Quarterly.

In fact, if you’re really into this stuff, another article I frequently recommend here is something published in the Chicago Reader back in 2006: “They need it, we waste it,” a provocative look at the future interstate politics of freshwater, projecting a time when cities like Phoenix, Las Vegas, and even L.A. might come, buckets in hand, begging for clean water from the Great Lakes. What impending hydro-political rearrangement of North America might we then see take shape?

An Invisible Empire of Sidewalks and Gutterspace

[Image: The Viele Map].

Because of a talk I’ll be giving tonight at the USC School of Architecture with Nicola Twilley of Edible Geography, I found myself re-reading an old post here about fishing in the basements of Manhattan.

[Image: The Viele Map].

Manhattan being an island once thoroughly criss-crossed by ponds and streams, almost all of which have been sealed in concrete and turned into sewers, this somewhat hallucinatory theory goes that some of those streams might still be accessible: just smash down through your building’s basement floor, uncover the island’s lost hydrology of well-braided rivers and streams, and an angling paradise will be accessible at your feet.

[Image: The Viele Map via Kottke.org].

But what really caught my eye, and what I’m actually posting about here, is a “gutterspace” reclamation project inaugurated by a man named Jack Gasnick, something I rediscovered today after following a link at the end of that post, which leads to the long-defunct blog Urbablurb by Giles Anthony.

[Image: From Gordon Matta-Clark’s Fake Estates, via Free Association Design].

This is how Anthony describes Gasnick’s project:

In the early 1970s—unbelievably, given how influential Gordon Matta-Clark has become in the last few years—Gasnick began buying and collecting “gutterspace,” or small slivers of land left over from zoning or surveying errors. He said that after a little while he couldn’t stop: “It’s like collecting stamps; once you’ve got the fever, you’ve got the fever.”

Accordingly, Gasnick “bought a slice in Corona just behind Louis Armstrong’s house,” Urbablurb continues, “a piece near Jamaica Bay where he once filled a pail with sea-horses, and yet another adjacent to the Fresh Kills landfill where he claims an abandoned sea Captain’s house still stood.” Gasnick then cultivated small patches of parkland and wilderness within those areas—a micro-wilding of the metropolis, one site at a time: “On the weekends, he would sometimes drive out to the tiny parcels and help the milkweed and laurel grow, tend to the turtles, and sit down for a picnic. ‘This jump of mine from flower pot to apple tree bears witness to the fact that it doesn’t cost much for an apartment-living guy to get a share of the good environment,’ he wrote in 1974. To be exact, it cost between $50 and $250. But the taxes he had to pay were enough of a hassle that he gave away (or otherwise lost track of) all the pieces by 1977.”

He “lost track” of them—the mind reels at the possibility that there is still a distributed Jack Gasnick estate somewhere, peppering the streets and gutters of New York City.

As Anthony suggests, this all has an uncanny parallel in Gordon Matta-Clark’s Fake Estates project. From Cabinet magazine:

In the early 1970s, Matta-Clark discovered that the City of New York periodically auctioned off “gutterspace”—unusably small slivers of land sliced from the city grid through anomalies in surveying, zoning, and public-works expansion. He purchased fifteen of these lots, fourteen in Queens and one in Staten Island. Over the next years, he collected the maps, deeds, and other bureaucratic documentation attached to the slivers; photographed, spoke, and wrote about them; and considered using them as sites for his unique brand of “anarchitectural” intervention into urban space.

So who is Jack Gasnick, that minor New Yorker who once “bought strange-shaped lots in every borough,” as the New York Times reported back in 1994, when Gasnick was still alive and 74 years old, and who once claimed to fish in the basements of Manhattan? Who knows.

(The BLDGBLOG/Edible Geography presentation tonight at USC is at 6pm in Harris Hall; it’s free and open to the public. We’ll be talking about buried rivers, artificial glaciers, and quarantine, among other shared topics of interest).
