1953 Map of Casa Diablo Mtn

About this map

Crowley Lake and the Owens River dominate this 1950s landscape, where hydroelectric development meets a storied mining history. The map shows the Long Valley Dam and a Power House downstream, illustrating the era's focus on water management and energy production in the Eastern Sierra. The rugged terrain of the Benton Range and the Volcanic Tableland is dotted with numerous extraction sites, including the Casa Diablo Mine and the Kings Mill (Site). Local travel and forestry are anchored by hubs like Toms Place and the Rock Creek Guard Sta. The presence of small settlements and camps such as North Landing, South Landing, and Sherwin Ranch highlights the scattered nature of habitation in this high-altitude region before modern expansion. This survey details the complex network of springs like Moran Spring and creeks that sustain the area between the Glass Mtn Ridge and the Wheeler Crest.
