Keystone Mountain and Newton Mountain dominate this corner of Lincoln County, defined by a series of high ridges and deep drainages. The landscape is marked by a history of extraction and monitoring, with the Keystone Mine, Morning Glory Mine, and Black Diamond Mine scattered across the slopes. A network of specialized equipment, including the Friday Hill Snow Gage and Fourth of July Snow Gage, suggests the importance of water resource management and winter snowpack tracking in these mountains.
