Supergrass, or the Anthropocene is Local

[Image: Artificial grass stretches onto a sidewalk in Somerville, MA; Instagram by BLDGBLOG].

While reading that “land use has already pushed biodiversity below the level proposed as a safe limit,” possibly setting the stage for an irreversible decline in biological variety around the world, it’s worth recalling a somewhat tragicomic article published last week warning that Britain has so many artificial lawns, these so-called permanent botanicals are now considered a threat to wildlife.

From the Guardian:

From local authorities who purchase in bulk for use in street scaping, to primary schools for children’s play areas and in the gardens of ordinary suburban family homes, the sight of pristine, green artificial grass is becoming a familiar sight. One company has registered a 220% year-on-year increase in trade of the lawns.
But as families, councils and schools take to turfing over their open spaces with a product which is most often made from a mix of plastics—polypropylene, polyurethane and polyethylene—there is growing alarm amongst conservationists and green groups.
They say the easy fix of a fake lawn is threatening the habitat of wildlife, including butterflies, bees and garden birds as well as creating waste which will never biodegrade.

I’m reminded of the artificial gardens of Don DeLillo’s new novel, Zero K, where plastic trees and flowers tremble lifelessly in an air-conditioned breeze, installed as part of a remote desert complex devoted to human immortality.

Only here, it’s the everyday landscape of Britain, slowly but surely being plasticized, replaced by a chemical surrogate for living matter, this ubiquitous manufactured stand-in for the picturesque English gardens of an earlier generation.

Lost butterflies flutter over plastic lawns, smelling nothing but petrochemicals. Bees land on the petals of polyester flowers and pick up the dust of industrial dyes rather than pollen. Excess drops of translucent glue glow in the afternoon sunlight.

The anthropocene is not only a global transformation; it takes place in—it takes the place of—your own backyard.

You might recall our earlier look at the work of Dutch photographer Gerco de Ruijter, who has been documenting the landscape phenomenon known as “grid corrections,” or where the U.S. road system is forced to deviate in order to account for the curvature of the Earth.

De Ruijter has now animated many dozens of those photos, with a soundtrack by Michel Banabila, into a one-minute video, embedded above. Watch roads tick into and out alignment across the American plains, as a grid of rectilinear lines faces geometric defeat on the surface of a sphere.

“Building with metals not from Earth”

I missed the story last month that a company called Planetary Resources had successfully 3D-printed a small model using “metals not from Earth”—that is, metal harvested from a meteorite. “Transforming a chunk of space rock into something you can feed into a 3D printer is a pretty odd process. Planetary Resources uses a plasma that essentially turns the meteorite into a cloud that then ‘precipitates’ metallic powder that can be extracted via a vacuum system. ‘It condenses like rain out of a cloud,’ said [a company spokesperson], ‘but instead of raining water, you’re raining titanium pellets out of an iron nickel cloud.’ (…) ‘Everyone has probably seen an iron meteorite in a museum, now we have the tech to take that material and print it in a metal printer using high energy laser. Imagine if we could do that in space.’”

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.

ForestRings1[Image: From the thesis “Geochemistry of Forest Rings in Northern Ontario: Identification of Ring Edge Processes in Peat and Soil” (PDF) by Kerstin M. Brander, University of Ottawa].

“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.

Geochemistry of Forest Rings in northern Ontario:[Image: From the thesis “Geochemistry of Forest Rings in Northern Ontario: Identification of Ring Edge Processes in Peat and Soil” (PDF) by Kerstin M. Brander, University of Ottawa].

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.

rings[Image: Screen-grab from Google Maps].

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.

ForestRings3[Image: From the paper “Spontaneous potential and redox responses over a forest ring” (PDF) by Stewart M. Hamilton and Keiko H. Hattori].

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.

ForestRings4[Image: From the paper “Spontaneous potential and redox responses over a forest ring” (PDF) by Stewart M. Hamilton and Keiko H. Hattori].

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.

ForestRings5[Image: Forest ring at N 49° 16′ 05″, W 83° 45′ 01″, via Google Maps].

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.

ForestRings6[Image: Forest rings at N 49° 29′ 48″, W 80° 05′ 40″, via Google Maps].

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.

Comparative Astral Isochrones

[Image: Isochronic map of travel distances from London, from An Atlas of Economic Geography (1914) by John G. Bartholomew (via)].

“This is an isochronic map—isochrones being lines joining points accessible in the same amount of time—and it tells a story about how travel was changing,” Simon Willis explains over at Intelligent Life. The map shows you how long it would take to get somewhere, embarking from London:

You can get anywhere in the dark-pink section in the middle within five days–to the Azores in the west and the Russian city of Perm in the east. No surprises there: you’re just not going very far. Beyond that, things get a little more interesting. Within five to ten days, you can get as far as Winnipeg or the Blue Pearl of Siberia, Lake Baikal. It takes as much as 20 days to get to Tashkent, which is closer than either, or Honolulu, which is much farther away. In some places, a colour sweeps across a landmass, as pink sweeps across the eastern United States or orange across India. In others, you reach a barrier of blue not far inland, as in Africa and South America. What explains the difference? Railways.

Earlier this year, when a private spacecraft made it from the surface of the Earth to the International Space Station in less than six hours, the New York Times pointed out that “it is now quicker to go from Earth to the space station than it is to fly from New York to London.”

[Image: From Twitter].

In the context of Bartholomew’s map, it would be interesting to re-explore isochronal cartography in our own time, to visualize the strange spacetime we live within today, where the moon is closer than parts of Antarctica and the International Space Station is a shorter trip than flying to Heathrow.

Dead Ringer

[Image: Mars’s moon, Phobos; courtesy NASA /JPL/University of Arizona].

Oh, to live another 40 million years… “One day,” Nature reports, “Mars may have rings like Saturn does”:

The martian moon Phobos, which is spiralling inexorably closer towards the red planet, will disintegrate to form a ring system some 20 million to 40 million years from now, according to calculations published on 23 November. Other research suggests that long grooves on Phobos’s surface may represent the first stages of that inevitable crack-up.

After that point, a red mineral ring will gradually coalesce from the dust storm, circling the planet in a desert halo.

In terms of human experience, 20-40 million years obviously dwarfs our anatomical and genetic history as modern Homo sapiens, and I am excessively confident that no humans will be around to witness this event. Nonetheless, it’s not actually that far off. The Earth itself is 4.5 billion years old; 20-40 million years is the geological blink of an eye. In a sense, we will just miss it.

For what it’s worth, Neal Stephenson’s most recent novel, Seveneves, is about a similar event—but set on Earth, not Mars.

“What if Earth’s moon suddenly and spontaneously broke apart into seven large pieces?” a review in the New York Times asked. “What would happen to life on Earth? It’s an intriguing premise, one that could conceivably go in any number of interesting directions. What would be the ramifications for every aspect of society, including economics, governance, the rule of law, privacy and security, not to mention even more fundamental matters like reproductive rights, religion and belief?”

The Drowned World

[Image: From Terra Forming: Engineering the Sublime by Adam Lowe and Jerry Brotton].

Artists Adam Lowe and Jerry Brotton’s project Terra Forming: Engineering the Sublime simultaneously explores the history of different geographic projections—including how these have been used to misrepresent and distort the earth’s surface—and at the future of that earth in an era of rising sea levels.

[Image: From Terra Forming: Engineering the Sublime by Adam Lowe and Jerry Brotton].

As Factum Arte explain, their chosen geographic projections offer “a way of engaging with the Earth from different points of view, and reflect historical ways of mapping the world from the Greeks to Google Earth.”

[Image: From Terra Forming: Engineering the Sublime by Adam Lowe and Jerry Brotton].

The projections are milled into beautiful 3D topographic models, with the vertical axis exaggerated to allow for changes in altitude to become visible.

The Andes, for example, become an abrupt spine of skyscraping pinnacles on the edge of an otherwise dead-flat continent, and deep-sea plains become spiky fields of underwater needles and pins.

[Images: From Terra Forming: Engineering the Sublime by Adam Lowe and Jerry Brotton].

As the artists write, “distortion was used because without it the globe’s surface would appear almost totally flat”—which interestingly suggests that representational distortion, with a great deal of irony, is actually central to giving our planet geographic legibility.

To map it or to know it, the implication seems to be, you must first alter it.

[Image: From Terra Forming: Engineering the Sublime by Adam Lowe and Jerry Brotton].

This is only half the project, however.

The artists refer to Terra Forming as “a cartographic response to the advent of the Anthropocene“—which is why the resulting topographic models are then flooded.

[Images: From Terra Forming: Engineering the Sublime by Adam Lowe and Jerry Brotton].

“The installation will mimic the passage of time as well as space,” Factum Arte write, “by flooding the world with water over several days, until we reach current sea levels; the world will then be flooded completely, leaving us with a drowned world, a prescient image for those parts of the world facing rising sea levels, as well as those such as parts of the Arabian Peninsula which is trying to reclaim land from the sea.”

Village Design as Magnetic Storage Media

[Image: “Magnetic Field” by Berenice Abbott, from The Science Pictures (1958-1961)].

An interesting new paper suggests that the ritual practice of burning parts of villages to the ground in southern Africa had an unanticipated side-effect: resetting the ground’s magnetic data storage potential.

As a University of Rochester press release explains, the “villages were cleansed by burning down huts and grain bins. The burning clay floors reached a temperature in excess of 1000ºC, hot enough to erase the magnetic information stored in the magnetite and create a new record of the magnetic field strength and direction at the time of the burning.”

What this meant was that scientists could then study how the Earth’s magnetic field had changed over centuries by comparing more recent, post-fire alignments of magnetite in the ground beneath these charred building sites with older, pre-fire clay surrounding the villages.

The ground, then, is actually an archive of the Earth’s magnetic field.

If you picture this from above—perhaps illustrated as a map or floor plan—you can imagine seeing the footprint of the village itself, with little huts, buildings, and grain bins appearing simply as the outlines of open shapes.

However, within these shapes, like little windows in the surface of the planet, new magnetic alignments would begin to appear over decades as minerals in the ground slowly re-orient themselves with longterm shifts in the Earth’s magnetic field, like differently tiled geometries contrasting with the ground around them.

[Image: “Untitled” by Larry Bell (1962), via the L.A. Times, via Christopher Hawthorne].

What really blows me away here, though, is the much more abstract idea that the ground itself is a kind of reformattable magnetic data storage system. It can be reformatted and overwritten, its data wiped like a terrestrial harddrive.

While this obviously brings to mind the notion of the planetary harddrive we explored a few years ago—for what it’s worth, one of my favorite posts here—it also suggests something quite strange, which is that landscape architecture (that is, the tactical and aesthetic redesign of terrain) and strategies of data management (archiving, cryptography, inscription) might someday go hand in hand.

The Town That Creep Built

[Image: A curb in Hayward reveals how much the ground is drifting due to “fault creep”: the red-painted part is slowly, but relentlessly, moving north. Photo by Geoff Manaugh].

South of San Francisco, a whole town is being deformed by plate tectonics. These are the slow but relentless landscape effects known as “fault creep.”

An earlier version of this post was first published on The Daily Beast.

The signs that something’s not right aren’t immediately obvious, but, once you see them, they’re hard to tune out.

Curbs at nearly the exact same spot on opposite sides of the street are popped out of alignment. Houses too young to show this level of wear stand oddly warped, torqued out of synch with their own foundations, their once strong frames off-kilter. The double yellow lines guiding traffic down a busy street suddenly bulge northward—as if the printing crew came to work drunk that day—before snapping back to their proper place a few feet later.

This is Hollister, California, a town being broken in two slowly, relentlessly, and in real time by an effect known as “fault creep.” A surreal tide of deformation has appeared throughout the city.

[Image: “Fault creep” bends the curbs in Hollister; photo by Geoff Manaugh].

As if its grid of streets and single-family homes was actually built on an ice floe, the entire west half of Hollister is moving north along the Calaveras Fault, leaving its eastern streets behind.

In some cases, doors no longer fully close and many windows now open only at the risk of getting stuck (some no longer really close at all).

Walking through the center of town near Dunne Park offers keen observers a hidden funfair of skewed geometry.

[Image: 359 Locust Avenue, Hollister; photo by Geoff Manaugh].

For example, go to the house at 359 Locust Avenue.

The house itself stands on a different side of the Calaveras Fault than its own front walkway. As if trapped on a slow conveyor built sliding beneath the street, the walk is being pulled inexorably north, with the effect that the path is now nearly two feet off-center from the porch it still (for the time being) leads to.

[Image: The walkway is slowly creeping north, no longer centered with the house it leads to; photo by Geoff Manaugh].

In another generation, if it’s not fixed, this front path will be utterly useless, leading visitors straight into a pillar.

Or walk past the cute Victorian on 5th Street. Strangely askew, it seems frozen at the start of an unexpected metamorphosis.

[Image: Photo by Geoff Manaugh].

Geometrically, it’s a cube being forced to become a rhomboid by the movements of the fault it was unknowingly built upon, an architectural dervish interrupted before it could complete its first whirl.

Now look down at your feet at the ridged crack spreading through the asphalt behind you, perfectly aligned with the broken curbs and twisted homes on either side.

This is the actual Calaveras Fault, a slow shockwave of distortion forcing its way through town, bringing architectural mutation along with it.

[Images: The Calaveras Fault pushes its way through Hollister; photos by Geoff Manaugh].

The ceaseless geometric tumult roiling just beneath the surface of Hollister brings to mind the New Orleans of John McPhee, as described in his legendary piece for The New Yorker, “Atchafalaya.”

There, too, the ground is active and constantly shifting—only, in New Orleans, it’s not north or south. It’s up or down. The ground, McPhee explains, is subsiding.

“Many houses are built on slabs that firmly rest on pilings,” he writes. “As the turf around a house gradually subsides, the slab seems to rise.” This leads to the surreal appearance of carnivalesque spatial side-effects, with houses entirely detached from their own front porches and stairways now leading to nowhere:

Where the driveway was once flush with the floor of the carport, a bump appears. The front walk sags like a hammock. The sidewalk sags. The bump up to the carport, growing, becomes high enough to knock the front wheels out of alignment. Sakrete appears, like putty beside a windowpane, to ease the bump. The property sinks another foot. The house stays where it is, on its slab and pilings. A ramp is built to get the car into the carport. The ramp rises three feet. But the yard, before long, has subsided four. The carport becomes a porch, with hanging plants and steep wooden steps. A carport that is not firmly anchored may dangle from the side of a house like a third of a drop-leaf table. Under the house, daylight appears. You can see under the slab and out the other side. More landfill or more concrete is packed around the edges to hide the ugly scene.

Like McPhee’s New Orleans, Hollister is an inhabitable catalog of misalignment and disorientation, bulging, bending, and blistering as it splits right down the middle.

And there’s more. Stop at the north end of 6th Street, for example, just across from Dunne Park, and look back at the half-collapsed retaining wall hanging on for dear life in front of number 558.

It looks like someone once backed a truck into it—but it’s just evidence of plate tectonics, the ground bulging northward without regard for bricks or concrete.

[Images: A fault-buckled wall and sidewalk bearing traces of planetary forces below; photos by Geoff Manaugh].

In fact, follow this north on Google Maps and you’ll find a clean line connecting this broken wall to the jagged rupture crossing the street in the photographs above, to the paper-thin fault dividing the house from its own front walk on Locust Avenue.

So what’s happening to Hollister?

“Fault creep” is a condition that results when the underlying geology is too soft to get stuck or to accumulate tectonic stress: in other words, the deep rocks beneath Hollister are slippery, more pliable, and behave a bit like talc. Wonderfully but unsurprisingly, the mechanism used to study creep is called a creepmeter.

The ground sort of oozes past itself, in other words, a slow-motion landslide at a pace that would be all but imperceptible if it weren’t for the gridded streets and property lines being bent out of shape above it.

[Image: A curb and street drain popped far out of alignment in Hollister; photo by Geoff Manaugh].

In a sense, Hollister is an urban-scale device for tracking tectonic deformation: attach rulers to its porches and curbs, and you could even take measurements.

The good news is that the large and damaging earthquakes otherwise associated with fault movement—when the ground suddenly breaks free every hundred years or so in a catastrophic surge—are not nearly as common here.

Instead, half a town can move north by more than an inch every five years and all that most residents will ever feel is an occasional flutter.

[Images: Crossing onto the Pacific Plate (heading west) in Parkfield; photo by Geoff Manaugh].

I spoke with Andy Snyder from the U.S. Geological Survey about the phenomenon.

Snyder works on an experiment known as the San Andreas Fault Observatory at Depth, or SAFOD, which has actually drilled down through the San Andreas Fault to monitor what’s really happening down there, studying the landscape from below through sensitive probes installed deep in the active scar tissue between tectonic plates.

On Snyder’s advice, I made my way out to one of the greatest but most thoroughly mundane monuments to fault creep in the state of California. This was in Parkfield, a remote town with a stated population of 18 where Snyder and SAFOD are both based, and where fault creep is particularly active.

In Parkfield there is a remarkable road bridge: a steel structure that has been anchored to either side of the San Andreas Fault like a giant, doomed staple. Anyone who crosses it in either direction is welcomed onto a new tectonic plate by friendly road signs—but the bridge itself is curiously bent, warped like a bow as its western anchorage moves north toward San Francisco.

It distorts more and more every day of the month, every year, due to the slow effects of fault creep. Built straight, it is already becoming a graceful curve.

[Image: Looking east at the North American Plate in Parkfield; photos by Geoff Manaugh].

Parkfield is also approximately where fault creep begins in the state, Snyder explained, marking the southern edge of a zone of tectonic mobility that extends up roughly to Hollister and then begins again on a brief stretch of the Hayward Fault in the East Bay.

Indeed, another suggestion of Snyder’s was that I go up to visit a very specific corner in the city of Hayward, where the curb at the intersection of Rose and Prospect Streets has long since been shifted out of alignment.

Over the past decade—most recently, in 2011—someone has actually been drawing little black arrows on the concrete to help visualize how far the city has drifted in that time.

The result is 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.

[Images: A moving curb becomes an inadvertent compass for measuring seismic energy in Hayward; photos by Geoff Manaugh].

Attempting to visualize earthquakes on a thousand-year time span, or to imagine the pure abstraction of seismic energy, can be rather daunting; this makes it all the more surprising to realize that even the tiniest details hidden in plain sight, such as cracks in the sidewalk, black sharpie marks on curbs, or lazily tilting front porches, can actually be real-time evidence that California is on the move.

But it is exactly these types of signs that function as minor landmarks for the seismic tourist—and, for all their near-invisibility, visiting them can still provide a mind-altering experience.

Back in Hollister, Snyder warned, many of these already easily missed signs through which fault creep is made visible are becoming more and more hard to find.

The town is rapidly gentrifying, he pointed out, and Hollister’s population is beginning to grow as its quiet and leafy streets fill up with commuters who can no longer afford to live closer to Silicon Valley or the Bay. This means that the city’s residents are now just a bit faster to repair things, just a bit quicker to tear down structurally unsound houses.

One of the most famous examples of fault creep, for example—a twisted and misshapen home formerly leaning every which way at a bend in Locust Avenue—is gone. But whatever replaces it will face the same fate.

After all, the creep is still there, like a poltergeist disfiguring things from below, a malign spirit struggling to make itself visible.

Beneath the painted eaves and the wheels of new BMWs, the landscape is still on the move; the deformation is just well hidden, a denied monstrosity reappearing millimeter by millimeter despite the quick satisfaction of weekend repair jobs. Tumid and unstoppable, there is little that new wallpaper or re-poured driveways can do to disguise it.

[Image: Haphazard concrete patchwork in a formerly straight sidewalk betrays the slow action of fault creep; photo by Geoff Manaugh].

Snyder remembered one more site in Hollister that he urged me to visit on my way out of town.

In the very center of Hollister’s Dunne Park, a nice and gentle swale “like a chaise longue,” in his words, has been developing.

Expecting to find just a small bump running through the park, I was instead surprised to see that there is actually a rather large grassy knoll forming there, a rolling and bucolic hill that few people would otherwise realize is an active tectonic fault.

[Image: A fault-caused grassy knoll rises in the center of Dunne Park in Hollister; photo by Geoff Manaugh].

In fact, he said, residents have been entirely unperturbed by this mysterious appearance of a brand new landform in the middle of their city, seeing it instead as an opportunity for better sunbathing. Fault creep is not without its benefits, he joked.

Snyder laughed as he described the sight of a dozen people and their beach towels, all angling themselves upward toward the sun, getting tan in a mobile city with the help of plate tectonics.

[Note: An earlier version of this piece was first published on The Daily Beast (where I did not choose the original headline). I owe a huge thanks to Andy Snyder for the phone conversation in which we discussed fault creep; and the book Finding Fault in California: An Earthquake Tourist’s Guide by Susan Elizabeth Hough was also extremely useful. Finally, please also note that, if you do go to Hollister or Hayward to photograph these sites, be mindful of the people who actually live there, as they do not necessarily want crowds of strangers gathering outside their homes].

A Cenotaph for Tailings

[Image: From “Mining Cenotaph” by Alexis Quinteros Salazar; courtesy of the RIBA President’s Medals].

Here’s another project from the RIBA President’s Medals, this one by Alexis Quinteros Salazar, a student at the University of Chile in Santiago.

Called “Mining Cenotaph,” it imagines an “occupation” of the tailings piles that have become a toxic urban landmark and a spatial reminder of the region’s economic exploitation.

[Image: From “Mining Cenotaph” by Alexis Quinteros Salazar; courtesy of the RIBA President’s Medals].

A museum would be carved into the tailings; in Salazar’s words, this would be a “building that captures the history and symbolism behind mining, enhancing and revitalizing a memory that is currently disaggregated and ignored and has a very high touristic potential.”

[Image: From “Mining Cenotaph” by Alexis Quinteros Salazar; courtesy of the RIBA President’s Medals].

In an architectural context such as this, the use of the word “cenotaph” is a pretty clear reference to Étienne-Louis Boullée’s classic speculative project, the “Cenotaph for Newton.” Over multiple generations, that has become something of a prime mover in the history of experimental architectural design.

Punctured walls and ceilings bring light into the interior—

[Image: From “Mining Cenotaph” by Alexis Quinteros Salazar; courtesy of the RIBA President’s Medals].

—while the roof is a recreational space for visitors.

Of course, there are a lot of unanswered questions here—including the control of aerosol pollution from the tailings pile itself and that pile’s own long-term structural stability—but the poetic gesture of a public museum grafted into a pile of waste material is worth commending.

[Image: From “Mining Cenotaph” by Alexis Quinteros Salazar; courtesy of the RIBA President’s Medals].

The detail I might like this most is where the structure becomes a kind of inversion of Boullée’s dome, which was pierced to make its huge interior space appear illuminated from above by constellations. Here, instead, it is the perforations in the the rooftop that would glow upward from below, as if in resonance with the night skies high above.

[Image: From “Mining Cenotaph” by Alexis Quinteros Salazar; courtesy of the RIBA President’s Medals].

Salazar’s project brings to mind a few other proposals seen here over the years, including the extraordinary “Memorial to a Buried Village” by Bo Li and Ge Men, as well as Brandon Mosley’s “Mine Plug” (which actually took its name retroactively from that BLDGBLOG post).
