2023 Map of Diablo Peak

About this map

Diablo Peak rises as the central landmark of this high desert terrain in Lake County, defining a landscape shaped by dramatic escarpments and isolated water catchments. The topography is dominated by the massive Diablo Rim, which creates a sharp transition across the central and eastern sections of the quadrangle. This area is characterized by its reliance on seasonal water management, as evidenced by the presence of engineered features like Brief Reservoir and Slim Reservoir. To the northeast, the terrain softens into the Whiskey Hills, where West Whiskey Lake and Murphys Lake gather in natural depressions. The placement of these water sources and the sheer face of the rim reflect the logistical challenges of land use in this part of Oregon, where natural landmarks like Jackings Hole and Fourmile Point serve as essential orientation markers for navigators and land managers.
