Keystone serves as the central hub of activity in this 1950s survey of the central Black Hills, updated with early 1970s revisions. The landscape is defined by the granite peaks of the Black Hills National Forest, including Harney Peak and the world-renowned Mount Rushmore National Memorial. A deep history of resource extraction is evident through the numerous sites scattered across the ridges and gulches, such as the Holy Smoke Mine, Peerless Mine, and Etta Mine.
