In 1955, Ansel Adams came to LeConte Memorial Lodge in Yosemite National Park with Nancy Newhall to mount an exhibit "This is the American Earth," that represented the work of thirty-two photographers. The subsequent exhibition book designed and written by Newhall and David Brower, then Executive Director of the Sierra Club, was published in 1960. This book was the first of the Sierra Club's award-winning "Exhibit Format" book series, and is a testimonial to the need for conservation and protection of the environment. "This is the American Earth is one of the great statements in the history of conservation," proclaimed Supreme Court Justice William O. Douglas. It has been reprinted several times in the subsequent decades. You may read an excerpt from the foreword by David Brower: http://www.wildnesswithin.com/americanearth.html
