About this map

Inyo Mountains high-desert peaks dominate this 1980s landscape, where mining interests and steep terrain defined the local activity. The presence of the Riche Mine and Overholtz Mine, alongside numerous unnamed Prospects, indicates a history of mineral exploration throughout the central and southern reaches of the quadrangle. These operations are connected by a web of 4WD tracks that navigate the complex topography, providing the primary means of access through this part of the Inyo National Forest.

Drainage systems like Crooked Creek Canyon and Deadman Canyon carve through the western slopes, leading toward landmarks such as Devils Gate. In the east, the terrain opens into Cowhorn Valley and its smaller counterpart, Little Cowhorn Valley. The map serves as a detailed record of the resource extraction footprint and primitive transportation network in Inyo County during the late twentieth century.
