About this map

East Range peaks and desert canyons dominate this landscape in Pershing County, where the high ridges of Rockhill Mtn and Organ Peak overlook the wide expanse of Grass Valley. This 1990 provisional survey records a transition from the rugged mining activity of the mid-20th century to a more isolated ranching environment. Remnants of the region's mineral history are evident in the Little Jupiter Mine and Four Sisters Mine, alongside an Abandoned Mill in the southern reaches of Rockhill Canyon.

Water sources are critical landmarks in this arid terrain, with numerous named points such as Dolly Hayden Spring, Mustang Spring, and Point Spring providing essential resources for local operations like the Grass Valley Ranch and Hayden Ranch. The map also traces historic routes through the mountains, including Natchez Pass and Hayden Pass, which connect the canyon systems of Emigrant Canyon and Highrock Canyon to the valley floor.
