2017 Map of Signal Hill

About this map

Black Hills National Forest land dominates this section of the western South Dakota high country, where the landscape is carved by deep drainages like Hell Canyon and West Hell Canyon. Located along the border of Pennington and Custer counties, the terrain is defined by prominent rises including Signal Hill, Antelope Ridge, and Cooper Ridge. The availability of water in this arid upland is marked by several named points such as Bear Spring, Blacktail Spring, and Alkali Spring, which historically supported livestock and wildlife in the gaps between limestone breaks.
