FROM THE AIR there seems to be a system: recognizable designs, networks on the desert floor. Crosshatches of ridge and fissure. Lines that fan out from the source. The shadow of the airplane slips across basin and range. Frost forms between the plane's double windows, each geometric crystal an argument for the stillborn beauty of pure math. Eventually the cut of a road appears, as deep as a fossil in shale. Unbound by destination, a road simply for the sake of moving, however slowly, through miles of nothing. Through the system. The first grid is the strangest, the geometry of better living etched onto the desert floor: identical houses of a planned community pleated around the nucleus of a swimming pool. One and then another, until the desert is paved under streets and scattered with countless pools like a deck of blue cards.
