About this map

Angostura Reservoir dominates this South Dakota landscape, where the waters of the Cheyenne River are impounded within a complex geography of rugged draws and canyons. The western reaches extend into the Black Hills National Forest, a terrain marked by steep features like Tepee Mtn and the winding Sheps Canyon. The map reveals a transition from the protected forest lands to the recreational and residential developments clustered near the community of Angostura.

Evidence of modern infrastructure and tourism is clear through the network of local roads and dedicated paths, including the Sheps Canyon Horse Camp Trl and the Reservoir View Bike Trl. To the north, the proximity of Hot Springs and the Hot Springs Municipal Airport suggests the area's role as a regional hub. Numerous named drainage features such as Wall Canyon, Red Canyon, and Horse Camp Draw underscore the intricate erosion patterns typical of the Black Hills foothills.
