Tree bombs

Two earlier posts here have strangely merged in real life: while we were off soil-bombing Iceland, MIT’s Moshe Alamaro – of the famed anti-hurricane jet engine barges – was strafing the earth with tree seeds. It’s called “aerial reforestation.”

Back in 1997, Alamaro “designed conical canisters, of a starchy biodegradable material, which each contain a seedling packed in soil and nutrients. The canisters are dropped from a low-flying plane, so that they hit the ground at 200 m.p.h., and imbed themselves in the soil. Then the canisters decompose and the young trees take root. A large aircraft could drop as many as 100,000 saplings in a single flight: Alamaro’s system could plant as many as a million trees in one day.”

Whole forests, fired from F-16s. Stealth forestry.


Or, branching off from an earlier comment on the agri-militaristic possibilities of garden wars (“hotheaded dictators and war-time presidents decide to take turns garden-bombing each other” [see comments]), you’d get forest wars, landscape design by Cruise missile: launched from a ship in the Indian Ocean, soon there are rich deciduous forests in the hills of Afghanistan.


Aspen trees. Precision Seedlings®. Bunker busters dropped into the San Andreas fault, where genetically engineered redwood saplings grow so deep they knit the faultline back together…

Riot police discard their plastic bullets and tear gas canisters to fire baby tulip bulbs; you go home and flowers are growing from your wounds… All scars become gardens…

Or on CNN some morning we see ICBMs arcing out of the mid-Atlantic, submarine crews cheering, the hunt for a truly red October now over: new maple tree saplings have been fired – they are reforesting the eastern Canadian plateau –

Or it’s a threat: disarm – or we will reforest you… Using tree bombs…

Urban Fossil Value

[Image: J.M. Gandy, speculations toward the ruins of John Soane’s Bank of England – but, again, how about speculations toward the Bank of England’s fossils…?]

As Hurricane Rita carves away at the Gulf shore, Galveston burns, buses explode outside Houston, and New Orleans refloods through badly built and incompletely repaired levees, I stumbled upon an old article, from 1998, about fossilized cities.

Millions of years from now, in geographical regions “entombed by tectonic disturbances,” entire cities – “the abandoned foundations, subways, roads and pipelines of our ever more extensive urban stratum” – will actually come to form “future trace fossils.”

These “future trace fossils,” the article says, form easily preserved systems that are “a lot more robust than [fossils] of the dinosaurs. They include roads, houses and foundations.”

And yet, for all that, only those cities “that were rapidly buried by floods or sandstorms” will be “preserved for posterity.”

Los Angeles, for instance, “is on an upward trajectory, pushed by pressure from the adjacent San Andreas Fault system, and is doomed to be eroded away entirely.” But if a city is flooded, buried in sand, or otherwise absorbed downward, “the stage is set to produce ideal pickling jars for cities. The urban strata of Amsterdam, New Orleans, Cairo and Venice could be buried wholesale – providing, that is, they can get over one more hurdle: the destructive power of the sea.”

It is often remarked in architectural circles how megalomaniacal Nazi architect Albert Speer came up with his so-called theory of ruin value, in which he proposed a new Romano-Fascist Berlin designed to look good as a ruin in thousands of years.

But that’s boring – let’s talk about cities fossilizing over millions of years.

Urban fossil value.

The already buried, subterranean undersides of our Tube-hollowed, war-bunkered modern cities “will be hard to obliterate. They will be altered, to be sure, and it is fascinating to speculate about what will happen to our very own addition to nature’s store of rocks and minerals, given a hundred million years, a little heat, some pressure (the weight of a kilometre or two of overlying sediment) and the catalytic, corrosive effect of the underground fluids in which all of these structures will be bathed.”

Who knew, for instance, that plastics, “which are made of long chains of subunits, might behave like some of the long-chain organic molecules in fossil plant twigs and branches, or the collagen in the fossilized skeletons of some marine invertebrates”? Who knew, in other words, that plastics will fossilize?

Indeed, “with a favourable concatenation of tectonics and sea level, our species could leave behind in a geological instant a much more striking record than the dinosaurs left in a hundred million years.”

Sound dunes

“Sand dunes in certain parts of the world are notorious for the noises they make,” New Scientist reports, “as sand avalanches down their sides. Some [dunes] emit low powerful booms, others sound like drum rolls or galloping horses, and some are even tuneful. These dune songs have been reported to last for up to 15 minutes and can sound as loud as a low-flying airplane.”

To test for the causes, properties, and other effects of these sand dune booms, “Stéphane Douady of the French national research agency CNRS and his colleagues shipped sand from Moroccan singing dunes back to his lab to investigate.” There, Douady’s team “found that they could play notes by pushing the sand by hand, or with a metal handle.”

The transformation of a sand dune – and, by extension, the entire Sahara desert, indeed any desert – even, by extension, the rust deserts of Mars – into a musical instrument. Music of the spheres, indeed.

“When the sand avalanches, the grains jostle each other at different frequencies, setting up standing waves in the cascading layer, says Douady. These waves reinforce one another, making the layer vibrate like the surface of a loud speaker. ‘What’s funny is that in these massive dunes, only a thin layer of 2 or 3 centimetres is needed to set up the resonance,’ says Douady. ‘Soon all grains begin to vibrate in step.'”

Douady has so perfected his technique of dune resonance that he has now “successfully predicted the notes emitted by dunes in Morocco, Chile and the US simply by measuring the size of the grains they contain.” The music of the dunes, in other words, was determined entirely by the size, shape, and roughness of the sand grains involved, where excessive smoothness dampened the dunes’ sound.

I’m reminded of the coast of Inishowen, a peninsula south of Malin Head in the north of Ireland, where the rocks endlessly grind across one another in the backwash of heaving, metallic, grey Atlantic waves. Under constant pressure of the oceanic, the rocks carve into themselves and each other, chipping down over decades into perfectly polished and rounded spheres, columns, and eggs – as if Archimedean solids or the nested orbits of Kepler could be discovered on the Irish ocean foreshore –

– all glittering. The rocks, I later learned, were actually semi-precious stones, and I had a kind of weird epiphany, standing there above the hush and clatter of bejewelled rocks, rubbing and rubbed one to the other in the depopulated void of a coastal November. It was not a sound easy to forget.

Because the earth itself is already a musical instrument: there is “a deep, low-frequency rumble that is present in the ground even when there are no earthquakes happening. Dubbed the ‘Earth’s hum‘, the signal had gone unnoticed in previous studies because it looked like noise in the data.”

Elsewhere: “Competing with the natural emissions from stars and other celestial objects, our Earth sings like a canary – it drones on in a constant hum of a gazillion notes. If it were several octaves higher, and hence, audible to the human ear,” it could probably get recorded by the unpredictably omnidirectional antennas of ShortWaveMusic and… you could download the sound of the earth. Free Radio Interterrestrial. [Note: the “drones on” link, a sentence or two back, offers a contrary theory (published in 2000) about the origins of these planetary sound waves.]

Which, finally, brings us to Ernst Chladni and his Chladni figures, or: architectonic structures appearing in sand due to patterns of acoustic resonance. The architecture of sand, involving sound—or architecture through sound, involving sand. Silicon assuming structure, humming.

The gist of Chladni’s experiments involved spreading a thin layer of sand across a vibrating plate, changing the frequency at which the plate vibrated, and then watching the sand as it shivered round, forming regular, highly geometric patterns. Those patterns depended upon, and were formed in response to, whatever vibration frequency it was that Chladni chose.

So you’ve got sand, dune music, terrestrial vibration, some Chladni figures – one could be excused for wondering whether the earth, apparently a kind of carbon-ironic bell made of continental plates and oceanic resonators, is really a vast Chladni plate, vibrating every little mineral, every pebble, every grain of sand, perhaps every organic molecule, into complex, three-dimensional, time-persistent patterns for which we have no standard or even technique of measurement. Or maybe William Blake knew how to do it, or Pythagoras, or perhaps even Nikola Tesla, but…

The sound dunes continue to boom and shiver. The deserts roar. The continents hum.

Soil-bombing Iceland

The Soil Conservation Service of Iceland is in the midst of a rather heroic effort to de-desertify large parts of the country. Iceland, in fact, is the largest desert in all of Europe.

As the BBC says, “The only difference [between the Icelandic desert and] the Sahara is that the sand here is black. Pitch black – with glaciers towering above and the sea shimmering in the distance. And the wind howling in between.” Which sounds like quite a difference.

In any case, the desert’s origins are with human activity; it is an artificial landscape, bearing traces of the island nation’s earlier inhabitants: “Despite the rather frightening name of the country, Iceland was green when Vikings came to settle. About 60% of the country was covered in bushes, trees, grass and all that. (…) But the Vikings, aside from chopping down trees for their own needs, also brought along their sheep. And what do sheep do best? They eat anything that is green.”

What interests me here, aside from the ecological message – don’t overgraze your territory – is the Soil Conservation Service’s preferred method of re-seeding: they pack finely sorted and organized seeds – virtual ecosystems, yet to occur, chosen species by species – into bombs: “Iceland is big and sparsely populated. There are few roads. So, Icelanders decided to ‘bomb their own country’, dropping the fertiliser and seeds from a WW II DC 3 Dakota.”

Earth, delivered by warplane.

(You can also listen to this story, as I first did, through an often irritating BBC podcast.)

So the bombs collide with the planet, releasing condensed and virtual landscapes: seed-bombs. Soil-bombs. The Icelandic countryside soon becomes an ironic inversion of a warzone: where the bombs fall, trees, grass, and wildflowers grow.

Instead of the lunar landscape of the Nevada test site, for instance—

—you get the opposite: strange oases of green, or gardening by artillery.

Which, conveniently, brings me to a new BLDGBLOG project.

It’s a landscape proposal: Artillery Gardens.

Unfortunately, there already is, in London, a place called Artillery Gardens, but no matter. BLDGBLOG’s Artillery Gardens will require the following: a very large parcel of land; a Howitzer; several shotguns; a military engineer who can calculate launching arcs and target distances; and some seed-packing volunteers, preferably experienced gardeners. Constant gardeners, perhaps. Everyone would fill up as many shotgun shells and old Howitzer cases as they could, using odd, rare, or otherwise exciting combinations of exotic seed; we’d all don some earplugs; and then it could begin: you’d blast a garden into existence.

Landscape planning as field artillery calculation. Landscape-at-a-distance. Gardening by artillery.

Through explosion and gunfire and heavy artillery, a rare and fragile garden is born. Species by species, day by day, through blast radii and impact fields, with the “power of endless growth and self-reproduction,” these Artillery Gardens will grow.

War as a garden, pursued by other means.

Das Urpflanze Haus

In what is, by now, a very old Wired blurb, you can read about Stoner Age artist and alien implant conspiracist Paul Laffoley, apparently a trained architect, who has proposed “genetically engineered seeds as a solution to the housing shortage.”
The seeds, you see, would grow into plants, and those plants themselves would grow into the shapes of inhabitable buildings. They would actually be buildings. Imagine a rather light-headed Michael Crichton watching *Swiss Family Robinson* on DVD when Rem Koolhaas stops by – and you’d get what Paul Laffoley has named das Urpflanze Haus, or “the primordial plant house.”


[Image: the Urpflanze Haus… so small you can barely see it, however.]
You’d plant the seeds – or perhaps just one, like a new, Piranesian “Jack and the Beanstalk” – do some watering, perhaps spread a little fertilizer… and at some point your own house will grow.
Thomas De Quincey: “With the same power of endless growth and self-reproduction did my architecture proceed in dreams.”
But what then? Do you prune excess or unwanted rooms? Can you graft new floorplans into the tree’s genetic code?
And will you get sap all over your FCUKing clothes?
Instead of topiary gardens, rich feudal warlords of the somewhat immediate future, with coked-up guards patrolling razorwire perimeters holding AK-47s and driving stolen Humvees, will cultivate delicate architectural gardens full of intertwined Urpflanze Häusen, on well-watered terraces stretching off past the conflict-laden, desert horizon. The world’s eventual oldest living house will be planted by a fourteen year-old girl in the hills of Missouri, out-living the Anthropocene by uncountable hundreds of years.
“Laffoley’s portfolio,” Wired continues, which “includ[es] a human-powered vehicle and a time machine, echoes the weird science of Nikola Tesla and Buckminster Fuller: Intricate illustrations and collages graft ancient occultism, eccentric engineering, particle physics, and a dose of ufology onto obsessively detailed building plans for a surreal alternative future.”

Musicalizing the weather through landscape architecture

The idea of listening to a landscape – how to podcast a landscape, for instance – tends to be literally overlooked in favor of a site’s visual impact or even its smell. When I was in Greece a few years ago, for instance, hiking toward an abandoned village on Tilos, every step I took crushed wild onions, herbs, and different flowers, and a temporary envelope of scent, picked up by breezes, floated all around me as I walked uphill. I may not remember every single detail of what that path *looked* like – but I do remember how it *smelled*.
It was like hiking through salad.
In any case, you don’t often see people packing up the family car, or hopping onto a train, to tour Wales or the Green Mountains of Vermont so that they can listen to the hills – they’ll go out to look at autumn leaf colors, sure, or take photographs of spring wildflowers. But to go all the way to Wales so they can hear a particular autumn wind storm howling through the gorges, a storm that only lasts two days of every year? Specifically going somewhere to *listen to the landscape*.
Seasonal weather events and their sonic after-effects. The Great November Moan.
All of which brings me to the idea of sound mirrors.


Musicalizing a weather system through landscape architecture.
BLDGBLOG here proposes a series of sound mirrors to be built in a landscape with regular, annual wind phenomena. A distant gully, moaning at 2am every second week in October due to northern winds from Canada, has its low, droning, cliff-created reverb carefully echoed back up a chain of sound mirrors to supply natural soundscapes for the sleeping residents of nearby towns.
Or a crevasse that actually makes no sound at all has a sound mirror built nearby, which then amplifies and redirects the ambient air movements, coaxing out a tone – but only for the first week of March. Annually.
Landscape as saxophone.


It’s a question of interacting with the earth’s atmosphere through human geotechnical constructions. Through sound mirrors.
What you’d need: 1) Detailed meteorological charts of a region’s annual wind-flow patterns. 2) Sound mirrors. 3) A very large arts grant.
You could then musicalize the climate.
With exactly placed and arranged sound mirrors atop a mesa, for instance, deep inside a system of canyons – whether that’s in the Peak District or Utah’s Canyonlands National Park – or even in Rajasthan, or western Afghanistan – you could interact with the earth’s atmosphere to create music for two weeks every year, amplifying the natural sounds of seasonal air patterns.
People would come, camp out, check into hotels, open all their windows – and just listen to the landscaped echoes.


A few questions arise: in this context, does Stonehenge make any sounds? What if – and this is just a question – it was built not as a prehistoric astronomical device but as a *landscape wind instrument*? You’d be out there wandering around the Cotswolds, thinking oh – christ, it’s 5000 years ago and we’re lost, but: what’s that? I hear Stonehenge… And then you locate yourself.
Sonic landmark.
This raises the possibility of building smaller versions of these sound mirrors in urban neighborhoods so that, for instance, Berlin’s Prenzlauer Berg sounds different than Mitte, which sounds different than Kreuzberg – which sounds different than South Kensington, which is different than Gramercy Park… Etc.
You’d always know which district of the city you were in – even which city you were in, full stop – based on what the wind sounded like.
(Which reminds me of another idea: that, to attract people to a city without much going for it, you could *flavor the water supply*: make it taste like Doritos, for instance, and then sell that on huge billboards: buy your new home in Detroit, the water tastes like Doritos… the water tastes like tofurky…).
Second: is there a sonic signature to the US occupation of Baghdad? And I don’t mean rumbling Hummers and airplane engines, I mean what if all those Bremer walls –


– generate sounds during passing wind storms? All the American military bases of Iraq moaning at 3am as desert breezes pass by.
What does the occupation *sound like*?
A sonic taxonomy of architectural forms could begin…

Geotechnics

Direct intervention into the earth’s surface through technology – the coupling of the planet with technological objects – could be phrased as ‘geotechnical,’ a word I thought I invented – until I discovered that ‘geotechnics’ is already a long-standing professional concern of engineers and architects. Gone was the whiz-bang neologism, but born was an intense curiosity in what ‘geotechnical engineers’ actually do.
Unforeseen ground conditions. Reuse of old foundations. Ground investigation. Geological voids. Borehole geophysics. ‘Geo Frontiers 2005’. Ground engineering, which includes ‘international geotechnical events’ and ‘covers all aspects of the engineering of the ground’.
The vocabulary alone justifies awe. Where else can you read: ‘Sui Field compression project: the tectonic structure of Northern Pakistan’, and take it seriously?
Geosynthetics!
Ground improvement!
‘The geotechnics of contaminated land’!
Applied geology.
My enthusiasm coming here not from some pre-adolescent obsession with digging machines, but from the black-out inducing intellectual high of outright planetary engineering, a geosynthetic *Wunderproject*, where remote-sensing meets hydrological engineering, geotextiles, ground improvement, and mega-scale, antigravitational, interstellar industrial machines hovering 350 miles above the dark, unfinished surface of a geoengineered planet.
‘The engineering of the ground’!
After geotechnics, the whole planet could be already artificial, bearing marks of human intervention. To find in a moment of ultra-fast zoom-out cello-soundtracked awe that the earth you’re standing on is always, already, everywhere a huge Mt. Rushmore, a man-made, artificial, technological, geotechnic project.
A hollow earth, a geosynthetic planet. Sculpted from geotextiles.
Landscape architecture taken to the megalomaniacal extreme. And funded by multinational petroleum companies.

Milled landscapes / Michael Heizer

The question is whether you could hook-up a milling machine to the earth itself. Rather than exact, laser-cut incisions made into boards of hardwood, you would mill entire landscapes out of the open surface of the earth.

This could start small – cutting foundations, bore holes, etc. – but should immediately expand to include larger examples of terrestrial engineering: landscape architecture, earthworks, gardens, perhaps even dikes, dams, and other flood containment systems. The earth-miller could be operated like an ordinary, programmable milling machine today: you input the design required, the exact sequence and dimensions of the cuts, and the machine sets out, milling a new landscape into existence.

In a recent *New York Times Magazine* profile of earthworks/land-sculptor Michael Heizer, we read about “‘City,’ [Heizer’s] own version of Easter Island or Angkor Wat: a modernist complex of abstract shapes – mounds, prismoids, ramps, pits – to be spread across the valley. It was to be experienced over time, in shifting weather, not from a single vantage point or from above but as an accumulation of impressions and views gathered by walking through it. (…) ‘City,’ in its vastness, was meant to synthesize ancient monuments, Minimalism and industrial technology. The work derived inspiration from Mississippian tumuli (ancient North American mounds), the ball court at Chichen Itza in the Yucatan and La Venta in southern Tabasco… At the same time, it suggested airport runways and Modernist architecture.” (Michael Kimmelman, “Art’s Last, Lonely Cowboy”: 6 Feb 05).

Despite – or perhaps because of – the size of Heizer’s “City” (somewhere between the Washington Mall and Central Park, apparently), it’d be perfect for an earth-miller. Several programmable machines with self-sharpening mechanical grinders, pavement saws and rock sanders – and perhaps viab/nozzles, mentioned in an earlier post – set to work. It takes days, weeks even, but then it’s done: the milled landscape of a new earth, abstract volumes glowing in the sunlight.

“Instant City” on Mars

MIT’s Mars Homestead Project plans on one-upping Archigram and Buckminster Fuller both with its plans for high-tech, locally-fabricated homes on Mars. Each home will be outfitted with a garden, library, greenhouse, and private parking space, exporting middle class comforts deep into space; and all of it will be made locally, farmed from elements occurring naturally in the atmosphere and soil. Or ‘the surface,’ I should say…

After “a seven-month journey inside a container the size of a minivan” hopeful colonists will decamp into “a comfy home – made with locally produced red brick, metal and fiberglass”. The homes may even be built directly into Martian hillsides, forming Tolkien-esque towns accessible through multiple airlocks. The airlocks, in tandem with reinforced building materials, will prevent explosive pressure leaks: “Materials such as brick and stone will have to be lined or sealed with plastic or fiberglass, and sufficiently reinforced with soil or other materials to prevent the buildings from exploding.”

Meanwhile, the Mars Society has already constructed a prototype Martian city on Devon Island, Canada, called the Flashline Arctic Research Station. Even more interestingly, due to the very real fear of “cabin fever” and extreme claustrophobia – or other, as yet undiscovered, architectural pathologies – in Martian settlers, “‘we have added a psychiatrist to the project team, to evaluate those issues’,” claims Mark Homnick, co-founder of the Mars Homestead Project. (All quotations from Mark Baard, “Builders in a Strange Land,” 18 June 2004, Wired online; see also ExploreMarsNow.org).
