This is the American Earth

"First published in 1960, this landmark book originated in a historic exhibit and launched the Sierra Club Exhibit Format Series, creating a revolution in publishing and in conservation action and attitudes. Now a new clothbound edition, published to coincide with the Sierra Club's Centennial, once again makes these spectacular black-and-white images of the American landscape, framed by Nancy Newhall's luminous words, available to a new generation of readers."--the publisher. Besides many photographs by Ansel Adams, images by Phillip Hyde, Eliot Porter, Margaret Bourke-White, Edward Weston, Minor White, Henri Cartier-Bresson, and Jacob Riis are included.
