About this map

Keystone serves as a central point in this Tuolumne County landscape, where the Sierra Nevada foothills meet agricultural and infrastructure development. The map details a network of ranch lands, including the Burgeson Ranch and Kistler Ranch, the latter featuring its own Kistler Ranch Airport. This area is vital to California's water management, as evidenced by the presence of the Hetch Hetchy Aqueduct and Tulloch Dam Rd in the northwest.

The terrain is defined by drainages such as Green Spring Run, N Fork Wildcat Cr, and Andrew Cr, all flowing through a region dominated by Rushing Mountain. Local fire and resource management is anchored by the California Division of Forestry station near the eastern boundary. The road network, including Rushing Hill Lookout Rd and Rock River Rd, illustrates the intersection of rural ranching access and state-level infrastructure.
