About this map

The Keystone (Site) occupies a prominent position within the Hot Creek Range, reflecting the area's legacy of high-desert prospecting and resource extraction. This late-1960s survey, conducted in cooperation with the Atomic Energy Commission, documents a landscape shaped by both natural relief and human industry. Evidence of early activity is visible in the presence of kilns near Tybo Creek and a prospect north of Old Dominion Canyon.

Water sources like Keystone Spring and Italian Spring provided essential lifelines for the remote camps and workings that once dotted these canyons. The rugged topography is defined by the massive Flagstaff Mtn and Cine Mountain, while various drainages including Empire Canyon and Keystone Canyon carve through the limestone and volcanic formations. For researchers and historians, this map preserves the specific coordinates of ephemeral settlements and mining infrastructure in a transition period for central Nevada's high basins.
