1954 Map of Mount Rushmore

About this map

Keystone serves as the industrial and social hub of this mid-century survey, situated at the confluence of several gulches and the Chicago Burlington and Quincy railroad line. The landscape is defined by its mining heritage, with prominent operations such as the Holy Terror Mine, Etta Mine, and Joe Dollar Mine scattered across the surrounding peaks and ridges. The Mount Rushmore National Memorial occupies the southern portion of the sheet, while the northern terrain is marked by the expansive waters of Sheridan Lake and several prominent summits including Eagle Mountain and Silver Mountain. This period shows the region during its post-war development within the Black Hills National Forest, where established forestry infrastructure like the Harney Ranger Station 2 and a Lookout Tower on Boulder Hill supported the management of this heavily timbered mountain environment.
