1992 Map of Crystal Crag

USGS Topo · Published 1995

About this map

Devils Postpile stands as the central landmark of this high-elevation mountain terrain where the boundaries of the Ansel Adams Wilderness and John Muir Wilderness converge. The landscape is defined by the canyon of the Middle Fork San Joaquin River, featuring Rainbow Falls and Lower Falls, alongside the glacial basins of the Mammoth Lakes area. Transportation across the crest is limited to storied footpaths, including the John Muir Trail and the Pacific Crest National Scenic Trail, which navigate through Mammoth Pass. These routes connect remote meadows and springs like Reds Meadow to the high-alpine lakes such as Lake Mary, Lake George, and Crystal Lake. Geologic features like the Dragons Back, Pumice Butte, and the namesake Crystal Crag illustrate the volcanic and glacial forces that shaped this portion of the Sierra Nevada.
