1979 Map of Disaster Peak

About this map

Pacific Crest National Scenic Trail traverses the high-altitude boundary of the Toiyabe National Forest and Stanislaus National Forest, providing a detailed view of this high Sierra Nevada landscape during the late 1970s. The map captures the divide between Alpine and Tuolumne counties, where the headwaters of the East Fork Carson River and the Clark Fork originate among massive geological formations. Notable landmarks such as The Iceberg and Disaster Peak dominate the topography, while numerous small water bodies like Poison Lake and Whitecliff Lake dot the basins. The survey records a network of established paths including the Paradise Valley Trail, showing the primitive infrastructure used for forest management and wilderness access before modern digital mapping, including the specific locations of Carson Falls and various seasonal Springs.
