2020 Map of Diablo Peak

About this map

Diablo Peak rises as the central landmark in this high-desert landscape of Lake County, as documented by the U.S. Geological Survey in 2020. The topography is defined by the dramatic escarpment of the Diablo Rim, which overlooks a series of remote basins and seasonal water features. To the northeast, the Whiskey Hills and West Whiskey Lake reflect a history of colorful local place-naming, while features like Jackings Hole and Fourmile Point suggest the area's importance for early navigation and land use in the Oregon outback. Human modification of the arid environment is evident in the presence of Brief Reservoir and Slim Reservoir, while Murphy's Lake remains a notable natural hydrologic feature. The map maintains the Public Land Survey System grid, including townships t30s r18e and t31s r19e, which continue to define the boundaries of these isolated ranges.
