John Muir was one of our first and finest writers on the wilderness of the American West. Part of Muir's attractiveness to modern readers is the fact that he was an activist. He not only explored the West and wrote about its beauties-- he fought for their preservation. His successes dot the landscape in all the natural features that bear his name: forests, lakes, trails, glaciers. Here collected are some of his finest wilderness essays, ranging from Alaska to Yellowstone, from Oregon to the Range of Light-- the High Sierra.
