Instance Gate

[Image: Malta, Instragram by BLDGBLOG].

Down in the lower levels of Valletta’s fortified walls, an old bricked-up doorway resembles something from a computer game: an oddly colored bit of masonry you would knock aside with a hammer, or a subtle wave of a wand, to make a corridor appear leading much further into the geologic depths.

The underside of Valletta, of course, is already mazed with passages, from wartime bomb shelters to church crypts, abandoned rail tunnels to hotel sub-cellars, and the entire island of Malta, made from such easily cut rock, is home to warrens of prehistoric temples and catacombs.

That entryways into the labyrinth can be found is hardly surprising; that they can look so much like a chunky, 8-bit game landscape only adds to the sense of urban mythology.

[The phrase “instance gate,” at least as I use it, comes from World of Warcraft. It implies that through a certain gate is a world that only you or your group will experience; anyone stepping through the same gate after you will, in fact, enter an entirely different space to confront an entirely different world of experiences. It’s a great metaphor.]

“Today’s world has no equivalent”

[Image: Tromsø, Norway; photo by BLDGBLOG].

Ted Nield’s book Supercontinent: Ten Billion Years in the Life of Our Planet—previously discussed back in 2012—is an exercise in what has long been referred to here as landscape futures.

In Nield’s case, this means literally imagining what the surface of the Earth might look like after hundreds of millions of years’ worth of tectonic transformations have deformed it beyond all recognition. Supercontinent could thus be read alongside Jan Zalasiewiez’s The Earth After Us as a useful guide for thinking about radical landscape change on a truly inhuman timescale.

Nield writes, for example, that, “even if some civilization of 200 million years ago had completely covered [the Earth] in cities and then wiped itself out in some gigantic global nuclear holocaust, nothing—not even the faintest trace of some unnatural radioisotope—would now remain on the surface.” Some of us might think that writing books, for example, is a way to achieve immortality—or winning an Oscar or becoming a national leader—yet covering the entire planet with roads and buildings is still not enough to guarantee a place in any sort of collective future memory. Everything will be erased.

The book goes from a speculative, but apparently realistic, scenario in which subduction zones might open in the Caribbean—thus dragging North America back toward a seemingly inexorable collision with Eurasia—to the future implications of past tectonic activity. Supercontinents have come and gone, Nield reminds us, and the cycle of these mega-islands is “the grandest of all the patterns in nature.” “750 million years before Pangaea formed,” he writes, “yet another [supercontinent] broke up; and before that another, and so on and on, back into the almost indecipherable past.”

At one point, Nield asks, “what of older supercontinents? What of the supercontinent that broke up to give us Pangaea? And the one before that? Compared with Pangaea, those lost worlds seem truly lost. As with all geological evidence, the older it is, the less of it survives, the more mangled it has become and the harder it is to interpret.”

It is all but impossible to picture them—to see oneself standing on them—as you can with Pangaea. They have their magical names, which lend them reality of a sort despite the fact that, for some, even their very existence remains controversial. About Rodinia, Pannotia, Columbia, Atlantica, Nena, Arctica or distant Ur, the mists of time gather ever more thickly.

The amazing thing is that this cycle will continue: long after North America is expected to reunite with Eurasia, which itself will have collided with North Africa, there will be yet another splintering, following more rifts, more bays and inland seas, in ever-more complicated rearrangements of the Earth’s surface, breeding mountain ranges and exotic island chains. And so on and so on, for billions of years. Bizarre new animals will evolve and bacteria will continue to inter-speciate—and humans will long since have disappeared from the world, unable to experience or see any of these future transformations.

While describing some of the potential ecosystems and landscapes that might result from these tectonic shifts, Nield writes that “our knowledge of what is normal behavior for the Earth is extremely limited.”

Indeed, he suggests, the present is not a key to the past: geologists have found “that there were things in the deepest places of Earth history for the unlocking of whose secrets the present no longer provided the key.” These are known as “no-analog” landscapes.

That is, what we’re experiencing right now on Earth potentially bears little or no resemblance to the planet’s deep past or far future. The Earth itself has been, and will be again, unearthly.

In any case, I mention all this because of a quick description found roughly two-fifths of the way through Nield’s book where he discusses lost ecosystems—landscapes that once existed here but that no longer have the conditions to survive.

Those included strange forests that, because of the inclination of the Earth’s axis, grew in almost permanent darkness at the south pole. “These forests of the polar night,” Nield explains, describing an ancient landscape in the present tense, “withstand two seasons: one of feeble light and one of unremitting dark. Today’s world has no equivalent of this eerie ecosystem. Their growth rings show that each summer these trees grow frenetically. Those nearer the coast are lashed by megamonsoon rains roaring in from [the lost continent] of Tethys, the thick cloud further weakening the feeble sunshine raking the latitudes at the bottom of the world.”

There is something so incredibly haunting in this image, of thick forests growing at the bottom of the world in a state of “unremitting” darkness, often lit only by the frozen light of stars, swaying now and again with hurricane-force winds that have blown in from an island-continent that, today, no longer exists.

Whatever “novel climates” and unimaginable geographies lie ahead for the Earth, it will be a shame not to see them.

Shocked to discover “they were living in ‘hill country’”

MysteriousUpswelling[Image: “Mysterious upswelling of Opp street above curb, Wilmington (1946),” courtesy USC Libraries].

In 1946, a “mysterious upswelling” occurred in a street in the neighborhood of Wilmington, California, near Long Beach. The photograph above, courtesy of the USC Libraries, pictures a young boy who went outside to measure it.

As part of an irregular series of short posts for KCET’s Lost L.A.—about things like Los Angeles partially illuminated by the light of an atomic bomb—I wrote a quick piece, inspired both by the photo itself and by its caption. “Surprising uprising,” it begins. “George Applegate measures mysterious swelling of Opp Street in Wilmington. Residents were shocked yesterday morning to discover they were living in ‘hill country.’ Street is seven inches above the curbing. Officials are investigating.”

Although I don’t mention this in the KCET post, I was instantly reminded of terrain deformation grenades and the instant, pop-up landforms of an old LucasArts game called Fracture. There, specialized weapons are put to use, tactically reshaping the earth’s surface, resulting in “mysterious upswellings” such as these.

There could be hills anywhere in Los Angeles, we might infer from this, lying in wait beneath our streets and sidewalks, prepping themselves for imminent exposure,” I write over at KCET. “A street today is a mountain tomorrow.”

Inland Sea

For two closely related projects—one called L.A.T.B.D., produced for the USC Libraries, and the other called L.A. Recalculated, commissioned by the 2015 Chicago Architecture Biennial, both designed with Smout Allen—I wrote that Los Angeles could be approached bathymetrically.

Los Angeles is “less a city, in some ways, than it is a matrix of seismic equipment and geological survey tools used for locating, mapping, and mitigating the effects of tectonic faults. This permanent flux and lack of anchorage means that studying Los Angeles is more bathymetric, we suggest, than it is terrestrial; it is oceanic rather than grounded.”

[Image: Underground seismic counterweights act as pendulums, designed to stabilize Los Angeles from below; from L.A. Recalculated by Smout Allen and BLDGBLOG].

Because of seismic instability, in other words, the city should be thought of in terms of depths and soundings, not as a horizontal urban surface but as a volumetric space churning with underground forces analogous to currents and tides.

This bathymetric approach to dry land came to mind again when reading last month that the land of Southern California, as shown by a recent GPS study, is undergoing “constant large-scale motion.”

It is more like a slow ocean than it is solid ground, torqued and agitating almost imperceptibly in real-time.

“Constant large-scale motion has been detected at the San Andreas Fault System in Southern California,” we read, “confirming movement previously predicted by models—but never before documented. The discovery will help researchers better understand the fault system, and its potential to produce the next big earthquake.”

[Image: “Vertical velocities” along the San Andreas Fault; via Nature Geoscience].

This is true, of course, on a near-planetary scale, as plate tectonics are constantly pushing land masses into and away from one another like the slow and jagged shapes of an ice floe.

But the constant roiling motion of something meant to be solid is both scientifically fascinating and metaphorically rich—eliminating the very idea of being grounded or standing on firm ground—not to mention conceptually intriguing when put into the context of architectural design.

That is, if architecture is the design and fabrication of stationary structures, meant to be founded on solid ground, then this “constant large-scale motion” suggests that we should instead think of architecture, at least by analogy, more in terms of shipbuilding or even robotics. Architecture can thus be given an altogether different philosophical meaning, as a point of temporary orientation and solidity in a world of constant large-scale surges and flux.

Put another way, the ground we rely on has never been solid; it has always been an ocean, its motion too slow to perceive.

Schrödinger’s Speleology, or the Stalking of “Entranceless Caves”

[Image: A cave entrance in France, via Wikipedia].

I recently finished reading Last Words by Michael Koryta, a detective novel largely centered on an unmapped fictional cave system in southern Indiana, part of the great karst belt near the border with Kentucky.

One interesting thing about the novel is that this cave, known in the book as “Trapdoor,” operates on many different narrative levels. Most obviously, of course, there’s the unreliable memory of a major character suspected—yet never officially accused—of committing a murder there, where the darkness of Trapdoor’s linked subterranean spaces becomes a kind of mental model for his own inability to recall what really happened, when a woman was (apparently) murdered in the cave’s depths.

There is also a subplot, though, revealed quite late in the book, in which disguised real estate deals and obscure land trust deeds have been premised on the subterranean potential of this land snaking along the region’s old creeks and rivers, transactions inked with the belief that Trapdoor’s passages might continue beneath distant parcels; in this way, the cave comes to represent the conspiratorial intentions of people otherwise unwilling to state their true goals.

Finding the true outer limits of the cave—that is, finding the land parcels that the cave secretly connects from below—becomes coextensive with discovering the truth about what occurred underground there so many years earlier.

[Image: Cave in Venezuela, photographed by Vittorio Crobu, courtesy European Space Agency].

It was these latter parts of the novel—including a handful of plot points I won’t get into—that reminded me of notes I’d taken from a book called the Encyclopedia of Caves several years ago. That book includes a short entry written by Nevin W. Davis, called “Entranceless Caves, Discovery of.”

As Davis describes them, “entranceless caves” are like speleological versions of Schrödinger’s cat: they exist, but they have not been verified. They are real—but perhaps not. They are both in the ground and nowhere.

At times, Davis’s text is almost like a koan: “Suppose the cave is totally unknown and has no entrance,” he writes. What exactly is such a thing, and how can we account for its presence (or absence) in the landscape? After all, these are caves that have not been—and perhaps cannot ever be—located.

He goes on to describe mathematical models used to generate a probability of subterranean connection: the calculated likelihood that physically inaccessible voids might exist beneath the surface of things, linking one part of the world to another.

[Image: Cave in Mexico, photographed by Vittorio Crobu, courtesy European Space Agency].

“Another consideration in searching for caves,” Davis continues, “is entrance lifetime. Caves are long-term features under the landscape with lifetimes measured in millions of years, whereas entrances to them are fleeting features with lifetimes measured in millennia.”

Cave entrances come and go, in other words, while the caves they once led to remain. They can be covered over, woven shut by tree roots, erased.

As Davis describes it, “leaves and twigs will soon cover and block small vertical entrances. Pits less than a meter in diameter”—tiny holes that can nonetheless lead to huge systems, such as the real-life Mammoth Cave or the fictional Trapdoor—“can be totally blocked in one season. Leaves blocking a small entrance are soon followed by roots and more leaves and it is not long before all traces of an entrance are gone.”

This leads to an activity he calls “stalking the elusive entranceless cave”—which, for what it’s worth, seems like a perfect metaphor for part of Koryta’s novel, in which the book’s amnesia-stricken potential murderer undergoes hypnosis. His memory is a cave with no entrance.

[Image: Cave in Venezuela, photographed by Vittorio Crobu, courtesy European Space Agency].

In any case, there can also be “false positives,” Davis warns. These would be caves that appear to have been detected but that are not, in fact, real. A “stalker” of previously unknown caves might find herself misled by patches of melted snow, for example, or by other signs that wrongly give the impression of warm air rising from empty passages below.

“The best condition to search for snow melt,” Davis suggests, instead, “is with a new snowfall in midwinter with an overcast sky, since sunlight can also give false positives by shining through snow cover onto rocks and melting the snow. This is a tried-and-true method that has led to countless new caves.” It’s cave-discovery weather.

In essence, this is a process of reading the landscape: interpreting its surface features in order to gain knowledge of these other, deeper dimensions.

[Image: An artificially enlarged entrance to Carlsbad Caverns; Instagram by BLDGBLOG].

The next entry in the Encyclopedia is also worth reading; it is simply called “Entrances,” by William B. White. “Some caves,” White writes, continuing the strangely existential thread of Davis’s work, “may have no entrances at all.”

White adds a new category here, what he calls the “concealed entrance.”

At least from an architectural point of view, what’s interesting is that this allows White and other speleologists to challenge the idea of there being a clean dividing line between inside and outside, between a cave and the Earth’s surface.

Instead, he suggests, a cave’s entrance should actually be thought of as a transition: the “cave entrance zone,” White writes, “is, in effect, a continuous sequence of microclimates,” one that eventually leads to a point at which there is no direct access to sunlight or to rainfall.

It is only at that point that you are truly “inside” the Earth. You have transitioned to the great interior.

[Image: Photographer unknown; image via Discovery Communications].

Briefly, White also points out that cave entrances are not only unstable in the temporal sense—as Davis mentioned, cave entrances can completely disappear over time.

However, they are also unstable spatially: that is, they can physically migrate through the landscape over thousands, or even tens, of years.

Due to continual rockfall, for example, a cave entrance “not only migrates deeper into the hill but also migrates upward as rocks break away,” Davis writes. This can potentially push a cave entrance dozens and dozens of feet from its original location, while the cave itself remains stationary. Imagine a mouth migrating across your body while your stomach stands still.

Of course, this also means that an entrance to a given cave system can abruptly migrate onto someone else’s property, or that it can even pop open, suddenly and dramatically changing the value of a particular piece of land.

The next thing you know, following an unusually intense summer rainstorm, you own the entrance to a cave.

[Image: A salt cave in Israel; image via Wikipedia].

Which brings us back to Michael Koryta’s novel. There, an unexpected opening into the unstable depths of Indiana’s fictional Trapdoor complex changes the lives of many characters not just for the worse, but for the tragic.

The cave, as Koryta depicts it, is a relentless and unsympathetic thing, a space always shifting, growing organically but not alive, invisible yet ubiquitous, moving beneath the surface of the landscape, connecting parcels of land, as well as the lives—and deaths—of the characters who thought they were just idly passing time above.

10-HaywardCornerWEB[Image: Photo by Geoff Manaugh].

Lacking any sort of seismically-themed historic preservation plan, this seemed all but inevitable: a city works crew has fixed, and thus destroyed, the amazing offset curb at the intersection of Rose and Prospect in Hayward, California, where seismic “creep” has been inadvertently tracked for decades.

From the L.A. Times:

Since at least the 1970s, scientists have painstakingly photographed the curb as the Hayward fault pushed it farther and farther out of alignment. It was a sharp reminder that someday, a magnitude 7 earthquake would strike directly beneath one of the most heavily populated areas in Northern California.
Then, one early June day, a city crew decided to fix the faulty curb—pun intended. By doing what cities are supposed to do—fixing streets—the city’s action stunned scientists, who said a wonderful curbside laboratory for studying earthquakes was destroyed.

As you can see here, small black lines had been drawn on the curb as a visual aid for helping measure exactly how far its opposing sides had been displaced by so-called “fault creep.”

11-HaywardCornerWEB[Image: Photo by Geoff Manaugh].

The curb on the west is moving north—along with the rest of that part of Hayward, California—while the curb on the east basically marks the edge of a different tectonic plate.

I was there roughly two years ago, looking at fault creep up and down California—primarily along the San Andreas Fault—when I took these shots; at the time, I wrote that the intersection could be thought of as “something like an alternative orientation point for the city, a kind of seismic meridian—or perhaps doomsday clock—by which Hayward’s ceaseless cleaving can be measured.”

Alas, we’ll have to wait presumably until the 2050s before the curbs offset to anything like they were when these photographs were taken.

L.A. Recalculated

[Image: From L.A. Recalculated by Smout Allen and BLDGBLOG].

London-based architects Smout Allen and I have a project in the new issue of MAS Context, work originally commissioned for the 2015 Chicago Architecture Biennial and closely related to our project, L.A.T.B.D., at the University of Southern California Libraries.

Called L.A. Recalculated, the project looks at Greater Los Angeles as a seismically active and heavily urbanized terrain punctuated by large-scale scientific instrumentation, from geophysics to astronomy. This is explained in more detail, below.

Between the drawings and the text, it’s something I’ve been very enthusiastic about for the past year or so, and I’m thrilled to finally see it published. I thus thought I’d include it here on the blog; a slightly edited version of the project as seen on MAS Context appears below.

L.A. Recalculated
Commissioned for the 2015 Chicago Architecture Biennial

Los Angeles is a city where natural history, aerospace research, astronomical observation, and the planetary sciences hold outsized urban influence. From the risk of catastrophic earthquakes to the region’s still operational oil fields, from its long history of military aviation to its complex relationship with migratory wildlife, Los Angeles is not just a twenty-first-century megacity.

Its ecological fragility combined with an unsettling lack of terrestrial stability mean that Los Angeles requires continual monitoring and study: from its buried creeks to its mountain summits, L.A. has been ornamented with scientific equipment, crowned with electromagnetic antennae, and ringed with seismic stations, transforming Los Angeles into an urban-scale research facility, a living device inhabited by millions of people on the continent’s westernmost edge.

[Image: Models from the related project, L.A.T.B.D., by Smout Allen and BLDGBLOG; photo courtesy Stonehouse Photographic].

L.A. Recalculated can be seen as a distributed cartographic drawing—part map, part plan, part section—that takes conceptual inspiration from the book OneFiveFour by Lebbeus Woods. There, Woods describes a hypothetical city shaped by the existential threat of mysterious seismic events surging through the ground below. In order to understand how this unstable ground might undermine the metropolis, the city has augmented itself on nearly every surface with “oscilloscopes, refractors, seismometers, interferometers, and other, as yet unknown instruments,” he writes, “measuring light, movement, force, change.”

In this city of instruments—this city as instrument—“tools for extending perceptivity to all scales of nature are built spontaneously, playfully, experimentally, continuously modified in home laboratories, in laboratories that are homes,” exploring the moving surface of an Earth in flux. Architecture becomes a means for giving shape to these existential investigations.

Twenty-first-century Los Angeles has inadvertently fulfilled Woods’s speculative vision. It is less a city, in some ways, than it is a matrix of seismic equipment and geological survey tools used for locating, mapping, and mitigating the effects of tectonic faults. This permanent flux and lack of anchorage means that studying Los Angeles is more bathymetric, we suggest, than it is terrestrial; it is oceanic rather than grounded.

[Image: Models from the related project, L.A.T.B.D., by Smout Allen and BLDGBLOG; photo courtesy Stonehouse Photographic].

L.A. is also a graveyard of dead rocket yards and remnant physics experiments that once measured and established the speed of light using prisms, mirrors, and interferometers in the San Gabriel Mountains (an experiment now marked by historic plaques and concrete obelisks). Further, Los Angeles hosts both the Griffith and Mt. Wilson Observatories through which the region achieved an often overlooked but vital role in the history of global astronomy.

Seen through the lens of this expanded context, Los Angeles becomes an archipelago of scientific instruments often realized at the scale of urban infrastructure: densely inhabited, with one eye on the stars, sliding out of alignment with itself, and jostled from below with seismic tides.

[Image: From L.A. Recalculated by Smout Allen and BLDGBLOG].

The surface of Los Angeles is both active and porous. A constant upwelling of liquid hydrocarbons and methane gas is everywhere met with technologies of capture, mitigation, and control. In our proposal, wheeled seismic creepmeters measure the movement of the Earth as part of an experimental lab monitoring potentially hazardous leaks of oil and tar underground.

[Image: From L.A. Recalculated by Smout Allen and BLDGBLOG].

The speed of light was accurately measured for the first time just outside this city of sunshine and cinema. Using complex scientific instrumentation assembled from rotating hexagonal prisms, mirrors, and pulses of light, housed inside small, architecturally insignificant shacks in the mountains behind Los Angeles, one of the fundamental constants of the universe was cracked.

[Image: From L.A. Recalculated by Smout Allen and BLDGBLOG].

In the heart of the city, atop the old neighborhoods of Chavez Ravine, erased to make way for Dodger Stadium, we propose a series of 360º planetariums to be built. These spherical projections not only reconnect Los Angeles with the stars, constellations, and distant galaxies turning through a firmament its residents can now rarely see; they also allow simulated glimpses into the Earth’s interior, where the planet’s constantly rearranging tectonic plates promise a new landscape to come, a deeper world always in formation. The destroyed houses and streets of this lost neighborhood also reappear in the planetarium shows as a horizon line to remind visitors of the city’s recent past and possible future.

[Image: From L.A. Recalculated by Smout Allen and BLDGBLOG].

As the city changes—its demography variable, its landscape forever on the move—so, too, do the constellations high above. These shifting heavens allow for an always-new celestial backdrop to take hold and influence the city. A complex architectural zodiac is developed to give a new narrative context for these emerging astral patterns.

[Image: From L.A. Recalculated by Smout Allen and BLDGBLOG].

Seismic counterweights have long been used to help stabilize skyscrapers in earthquake zones. Usually found at the tops of towers, these dead weights sway back and forth during temblors like vast and silent bells. Here, a field of subterranean pendulums has been affixed beneath the city to sway—and counter-sway—with every quake, a kind of seismic anti-doomsday clock protecting the city from destruction.

[Image: From L.A. Recalculated by Smout Allen and BLDGBLOG].

All of the oil, tar, and liquid asphalt seeping up through the surface of the city can be captured. In this image, slow fountains attuned to these percolating ground fluids gather and mix the deeper chemistry of Los Angeles in special pools and reservoirs.

[Image: From L.A. Recalculated by Smout Allen and BLDGBLOG].

The endless jostling of the city, whether due to tectonic activity or to L.A.’s relentless cycles of demolition and construction, can be tapped as a new source of renewable energy. Vast flywheels convert seismic disturbance into future power, spinning beneath generation facilities built throughout the city’s sprawl. Los Angeles will draw power from the terrestrial events that once threatened it.

28_la_recalculated_08[Image: From L.A. Recalculated by Smout Allen and BLDGBLOG].

Through sites such as Griffith Observatory and the telescopes of Mt. Wilson, the history of Los Angeles is intimately connected to the rise of modern astronomy. The city’s widely maligned landscape of freeways and parking lots has been reinvigorated through the precise installation of gates, frames, and other architectural horizon lines, aligning the city with solstices, stars, and future constellations.

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.

Hot Rock, Lost Rock, Router

21012003800_7a51bd2882_z[Image: Keepalive by Aram Bartholl, from the artist’s Flickr page].

This past summer, Aram Bartholl installed a project called Keepalive in the woods of Neuenkirchen, Germany. Keepalive was a hollow boulder that contained “a thermoelectric generator which converts heat directly into electricity.”

Visitors are invited to make a fire next to the boulder to power up the wifi router in the stone which then reveals a large collection of PDF survival guides. The router which is NOT connected to the Internet offers the users [an opportunity] to download the guides and upload any content they like to the stone database. As long as the fire produces enough heat the router will stay switched on.

First, a chamber was cut into a large rock; the router was then installed inside it.

21189727272_1053f18340_z[Image: Keepalive by Aram Bartholl, from the artist’s Flickr page].

Next, the chamber was sealed with a piece of metal, and the rock itself was strapped to a delivery truck, to be dropped off in its new home in a wooded meadow.

Finally, a small campfire was started—and, lo and behold, the secret documents made their electromagnetic way to a nearby iPhone, as if conjured into digital existence through the most primitive means of a campfire.

It’s a kind of library in waiting.

21208073201_85db419959_z[Image: Keepalive by Aram Bartholl, from the artist’s Flickr page].

While the actual, technical realization of the piece leaves something to be desired—by which I simply mean that there is just a large metal plate hiding the cavity inside of which the router is stored, which is visually disappointing—I love the idea that a better-hidden version of this might actually serve a real survivalist purpose someday.

Out on the remote periphery of the city, where you and your family agree to meet should there ever be an earthquake, a hurricane, or an act of terrorism or war, a cached collection of digital files waits utterly hidden from view, sealed inside a boulder with no visible exterior signs. When the Big One hits, out to your hot rock you go.

Of course, in real life, you’d doubtless lose track of the thing and spend two agonizing weeks lighting fire after fire after fire under every boulder in the region, desperately checking your dying phones to see if the digital documents appear… and they never do…

Think, for example, of the genuinely weird—and seemingly half-fictional—story of “Rocky II,” artist Ed Ruscha’s lost geological sculpture in the California desert.

As the Guardian explains, “Rocky II” is a “little-known and unexhibited work by the American artist Ed Ruscha: an artificial rock made out of resin and named ‘Rocky II’ after the Sylvester Stallone movie. A BBC crew filmed Ruscha during its creation for a 1980 documentary, which also captured him depositing the work somewhere in the Mojave desert, where it has apparently remained ever since, indistinguishable from all the other rocks around it.”

Ruscha’s rock is apparently more than just forgotten, it is seemingly nonexistent: “‘Rocky II’ is so mysterious it neither appears on the call for information about missing artworks listed on the artist’s website, nor in the catalogue listing all his known works—almost as if its existence has been intentionally obscured.”

In any case, surely Bartholl’s Keepalive could also be used as an interesting geological tool for espionage, merely a different kind of spy rock, tucked away at a campsite somewhere, waiting for a foreign agent to come along and light a fire.

A few minutes later—invisibly, unexpectedly to anyone but the agent—a tiny router inside the rock whirs to life in the heat and an electromagnetic cache of classified files begins streaming.

Extra-Terrestrial Sand Dunes

Geologist Michael Welland has an interesting post up about the “first detailed examination of extra-terrestrial sand dunes” on Mars, coming later this year. His post also briefly discusses the life and career of Ralph Bagnold, after whom the Martian dunes are named, as well as the granular physics of a remote landscape that, in Welland’s words, “just seems, instinctively, to be unearthly.”


In the forests of northern Ontario, a “strange phenomenon” of large natural rings occurs, where thousands of circles, as large as two kilometers in diameter, appear in the remote landscape.

“From the air, these mysterious light-coloured rings of stunted tree growth are clearly visible,” the CBC explained back in 2008, “but on the ground, you could walk right through them without noticing them.”

Since they were discovered on aerial photos about 50 years ago, the rings have baffled biologists, geologists and foresters… Astronomers suggest the rings might be the result of meteor strikes. Prospectors wonder whether the formations signal diamond-bearing kimberlites, a type of igneous rock.

While it’s easy to get carried away with visions of supernatural tree rings growing of their own accord in the boreal forests, this is actually one of the more awesome examples of where the likely scientific explanation is also significantly more interesting than something more explicitly other-worldly.

Indeed, as geochemist Stew Hamilton suggested in 1998, the rings are most likely to be surface features caused by “reduced chimneys,” or “big centres of negative charge that frequently occur over metal deposits,” where a forest ring is simply “a special case of a reduced chimney.”

Reduced chimneys, meanwhile, are “giant electrochemical cells” in the ground that, as seen through the example of forest rings, can affect the way vegetation grows there.

One of many things worth highlighting here is this suggestion that the trees are being influenced from below by ambient electrochemical processes in the soil, set into motion by the region’s deep geology:

Hamilton was testing an analytical technique over a Matheson gold deposit to determine if there was any kind of geochemical surface signal. To his surprise, there were signals coming through 30 to 40 metres of glacial clay.

“We’re thinking there’s no way metals can move through clay 10,000 years after glaciation.”

After ruling out transport by ground water, diffusion and gas, he theorized it had to have been lifted to surface on electrical fields.

He applied the same theory to forest rings and discovered that they were also giant negatively charged cells.

Any source of negative charge will create a forest ring.

In landscape architecture terms, a forest ring—which Hamilton describes [PDF] as “a plant assemblage that is different from the surrounding forest making the features visible from the air”—could be seen as a kind of indirect electrochemical garden taking on a recognizably geometrical form without human intervention.

In effect, their shape is expressed from below. For ambitious future landscape designers, note that this implies a potential use of plantlife as a means for revealing naturally occurring electrical networks in the ground, where soil batteries and other forms of terrestrial electronics could articulate themselves through botanical side-effects.

That is, plant a forest; come back after twenty years; discover vast rings of negative electrochemical charge like smoke rings pushing upward from inside the earth.

Or, of course, you could reverse this: design for future landscape-architectural effects by formatting the deep soil of a given site, thus catalyzing subterranean electrochemical activity that, years if not generations later, would begin to have aesthetic effects.

But it gets weirder: as Hamilton’s fieldwork also revealed, there is a measurable “bulge in the water table that occurs over the entire length of the forest ring with a profound dip on the ring’s outer edge.” For Hamilton, this effect was “beyond science fiction,” he remarked to the trade journal Northern Ontario Business, “it’s unbelievable.”

What this means, he explained, is that “the water is being held up against gravity” by naturally occurring electrical fields.

Subsequent and still-ongoing research by other geologists and geochemists has shown that forest rings are also marked by the elevated presence of methane (which explains the “stunted tree growth”), caused by natural gas leaking up from geological structures beneath the forest.

Hamilton himself wrote, in a short report for the Ontario Geological Survey [PDF], that forest ring formation “may be due to upward methane seepage along geological structures from deeper sources,” and that this “may indicate deeper sources of natural gas in the James Bay Lowlands.”

Other hypotheses suggest that these forest rings could instead be surface indicators of diamond pipes and coal deposits—meaning that, given access to an aerial view, you can, in effect, “read” the earth’s biosphere as a living tissue of signs or symptoms through which deeper, non-biological phenomena (coal, diamonds, metals) are revealed.

Even better, these electrochemical effects stop on a macro-scale where the subsurface geology changes; as Hamilton points out [PDF], the “eastward disappearance of rings in Quebec occurs at the north-south Haricanna Moraine, which coincides with a sudden drop in the carbonate content of soils.”

If you recall that there were once naturally-occurring nuclear reactors burning away in the rocks below Gabon, then the implication here would be that large-scale geological formations, given the right slurry of carbonates, metals, and clays, can also form naturally-occurring super-batteries during particular phases of their existence.

To put this another way, through an accident of geology, what we refer to as “ground” in northern Ontario could actually be thought of a vast circuitboard of electrochemically active geological deposits, where an ambient negative charge in the soil has given rise to geometric shapes in the forest.

In any case, there is something pretty incredible about the idea that you could be hiking through the forests of northern Ontario without ever knowing you’re surrounded by huge, invisible, negatively charged megastructures exhibiting geometric effects on the plantlife all around you.

Several years ago, I wrote a post about the future of the “sacred grove” for the Canadian Centre for Architecture, based on a paper called “The sacred groves of ancient Greece” by art historian Patrick Bowe. I mention this because it’s interesting to consider the forest rings of northern Ontario in the larger interpretive context of Bowe’s paper, not because there is any historical or empirical connection between the two, of course; but, rather, for the speculative value of questioning whether these types of anomalous forest-effects could, under certain cultural circumstances, carry symbolic weight. If they could, that is, become “sacred groves.”

Indeed, it is quite thrilling and strange to imagine some future cult of electrical activity whose spaces of worship and gathering are remote boreal rings, circular phenomena in the far north where water moves against gravity and chemical reactions crackle outward through the soil, forcing forests to take symmetrical forms only visible from high above.
