Yosemite: The Embattled Wilderness

This history of Yosemite follows it as the seat of controversy

affecting the evolution of national parks, from its path-breaking

establishment in 1864 as a grant to California, 1890 expansion into a

national park, boundary reductions and loss of the Hetch Hetchy Valley,

evolution of wildlife science, management practices threatening Yosemite

Valley, and erosion of wilderness to the present day.
