2011 Map of Diablo Peak

About this map

Diablo Peak stands as the central topographic feature in this high desert landscape of Lake County, where the dramatic volcanic geology of the Great Basin is on full display. The area is defined by sharp escarpments and interior drainages, most notably the prominent Diablo Rim that cuts through the central and southern sections. Water is a scarce and precious resource in this environment, represented here by scattered seasonal catchments such as Murphys Lake, West Whiskey Lake, and the man-made Slim Reservoir. These water sources, along with the Whiskey Hills and landmarks like Jackings Hole, point to the region's history of range management and livestock grazing. Transportation is limited to the periphery, with E Summer Lake Rd providing the primary access along the western edge of this isolated terrain.
