John Burroughs,
Time and Change
“ The channels of the little streams are canyons, vertical sides of adobe soil, as deep as they are broad, rectangle grooves in the ground. Through all this arid region nature is abrupt, angular, and sudden—the plain squarely abutting the cliff, the cliff walling the canon; the dry water-course sunk in the plain like a carpenter's groove into a plank. Cloud and sky look the same as at home, but the earth is a new earth—new geologically, and new in the lines of its landscapes. It seems by the forms she develops that Nature must use tools that she long since discarded in the East. ”
