1990 Map of Tower Peak

About this map

Tower Peak rises as a central landmark where the high wilderness boundaries of the Sierra Nevada converge. This area is a complex meeting point of administrative and natural divisions, containing portions of Yosemite National Park, Toiyabe National Forest, and Stanislaus National Forest. The Pacific Crest National Scenic Trail traverses this high-elevation landscape, passing through Kennedy Canyon and near Dorothy Lake. Evidence of early alpine activity is found at the Montezuma Mine and the Piute Cabin located near Piute Canyon. Drainage patterns are dominated by the headwaters of the West Walker River and Jack Main Creek, which feed a network of high-altitude water bodies including Mary Lake, Lake Helen, and the Chain-of-Lakes. The map details the transition between the Emigrant Wilderness and the Yosemite Wilderness, illustrating the challenging terrain that defined early trans-Sierran routes like Bond Pass and Dorothy Lake Pass.
