About this map

Diablo Rim dominates this high-desert landscape in Lake County, defining the western edge of the quadrangle with its dramatic topographic shift. In this arid region, the distribution of water is the primary driver of human and animal activity, evidenced by the numerous named waterholes scattered across the plateau. Locations like Between Rim Waterhole, Wildcat Waterhole, and Yankee Waterhole highlight the vital importance of these small basins for range management and livestock in the mid-1980s.

South of the eponymous Sharp Top peak, the terrain gives way to the drainage of Sand Hollow and the isolated basins of Twin Lakes. This 1985 survey captures a snapshot of the high country before modern changes, documenting a network of unimproved roads and trails that connected these remote points of water. The concentration of features like Giant Waterhole and Sprinkle Waterhole reflects a landscape meticulously mapped for its most precious resource.
