A true Renaissance man, Muir was: inventor, mountaineer, explorer, botanist, geologist, nature-writer and environmental campaigner; many would add: Christian-mystic, visionary and wilderness-sage. His writings are the fountain-head from which the American conservation movement erupted, setting the agenda, the ethos and the argument for the creation of a vast National Park system. Muir did more than simply describe the grizzly bears, the giant redwoods and luminous landscapes of California's High Sierra; as the founder of the Sierra Club, his endless campaigns saved them for all posterity. This new selection includes Muir's finest autobiographical books: The Story of My Boyhood and Youth and My First Summer in the Sierra along with the best of his climbing and conservation essays from: The Mountains of California, Our National Parks, The Yosemite and Steep Trails. It offers a rounded portrait of Muir as a giant of American letters; of a visionary, whose passionate defence of 'everything that is Wild', still reverberates through today's environmental movement, inspiring new generations of activists and all who love the natural world.
