This recording of the 1931 book about Yosemite National Park comprises the narrative text about the Park from its discovery by non-natives in the Indian War of 1851 to the mid-twentieth century. The printed book contains dozens of early photographs and drawings, as well as an extensive timeline and bibliography, which are not here recorded. The author was an ecologist, historian, and administrator. He was an officer of the U.S. National Park Service for thirty four years, serving as the Chief Naturalist of Yosemite from 1923-1929 and later as Park Superintendent. - Summary by David Wales
