About this map

Mount Rushmore National Memorial anchors the northern reaches of this landscape, where the granite peaks of the southern Black Hills meet a complex network of forest roads and mountain tunnels. The infrastructure of the area is defined by the winding Iron Mountain Rd, which navigates the high elevations through the Doane Robinson Tunnel, C.C. Gideon Tunnel, and Scovel-Johnson Tunnel. This 2017 survey shows a region deeply shaped by recreation and memorialization within the Black Hills National Forest.

Water plays a central role in the topography, with Legion Lake and Center Lake serving as key landmarks alongside the flows of Grace Coolidge Cr and Grizzly Bear Cr. To the east, the settlement of Spokane sits near the Pennington and Custer County line. The map captures an intricate system of named draws and gulches, such as Potato Gulch and Norbeck Draw, which dictate the paths of early routes like the Custer Cutoff Rd.
