This is the noted photographer's last book project, begun two years before his death in 1984 at the suggestion of his friend, Wilderness Society president William Turnage. The straightforward design takes pertinent quotations from Adams's writings on wilderness conservation and interleaves them with informal subject groupings of photographs: Yosemite, ocean beaches, Yellowstone, Hawaii, trees, plants, and flowers. Turnage's warm introduction helps readers grasp in concrete terms the early shaping of Adams's commitment to nature conservation, his prodigious output and accomplishments, his visual legacy, and the success of his mission, spanning six decades, to preserve America's wild places. The quality of the large reproductions, from prints prepared by Adams's associate John Sexton, could not be finer. Recommended for photography, geography, and environmental science collections.
