Pioneer conservationist John Muir recounts his journeys by foot through the Yosemite Valley, Mount Whitney, the famed sequoia forests, King's Canyon, and other wilderness areas. With a natural historian's keen eye for flora, geography, and geology, he describes glaciers, lakes, trees, and the daily lives of the region's inhabitants. Muir's lyrical narrative, originally published in 1894, is accompanied by splendid illustrations of plants and animals.
