1979 Map of Disaster Peak

About this map

The Toiyabe National Forest and Stanislaus National Forest meet along the high ridges of the Sierra Nevada in this late-1970s topographical record. The landscape is defined by its verticality, anchored by prominent summits like Disaster Peak and Stanislaus Peak, with the high-altitude Pacific Crest National Scenic Trail winding through the center of the sheet. The drainage patterns of the East Fork Carson River and the Clark Fork illustrate the continental divide's influence on the local hydrology. High mountain basins contain scattered alpine waters including Whitecliff Lake, Boulder Lake, and Poison Lake. The map reveals a wild territory where historical human presence is marked primarily by pack trails and cattle-era names like Paradise Valley and Iceberg Meadow, indicating a land used for seasonal grazing and transit rather than permanent settlement.
