The light belies the bony solidity of the land, playing over it like emotion on a face, and in this the desert is intensely alive, as the apparent mood of mountains changes hourly, as places that are flat and stark at noon fill with shadows and mystery in the evening, as darkness becomes a reservoir from which the eyes drink, as clouds promise rain that comes like passion and leaves like redemption, rain that delivers itself with thunder, with lightning, with a rise of scents in this place so pure that moisture, dust, and the various bushes all have their own smell in the sudden humidity. Alive with the primal forces of rock, weather, wind, light, and time in which biology is only an uninvited guest fending for itself, gilded, dwarfed, and threatened by its hosts.
