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.
