In this volume, The National Parks: Preserving America's Wild Places, turn back the clock to 1872, when Congress established Yellowstone National Park as an area of unspoiled beauty for the "benefit and enjoyment of the people." Meet the visionaries, artists, and lovers of the American wilderness who fought against corruption and self-interest to carve out and protect these spaces for future generations. See for yourself how the idea of National Parks began, how they've changed, and how they continue to define America.
