About this map

The high crest of the Sierra Nevada defines this 1953 field survey, capturing the dramatic hydro-electric and recreational landscape of the High Sierra before later wilderness designations. The map details the significant water management infrastructure of the era, including the Thomas A Edison Lake and Florence Lake reservoirs, supported by the Hooper Diversion Dam and various gaging stations. These developments sit alongside historic backcountry routes like the John Muir Trail and the Silver Pass Trail, which provided access for early 20th-century explorers and packers.

Evidence of early resource extraction persists at the Pick and Shovel Mine near the northern boundary, while the shift toward alpine recreation is marked by seasonal outposts such as Fish Camp and Kip Camp. The map's dense cluster of named glacial lakes, such as Lake Italy and Marie Lake, and prominent peaks like Mt Abbot and Bear Creek Spire, provide a precise record of the geographic nomenclature used by the U.S. Geological Survey and the California Department of Water Resources during this period of mid-century alpine mapping.
