2012 Map of Flint Hill

About this map

The Cheyenne River winds through this southwestern South Dakota landscape, defining the topography south of Chilson Mountain and Flint Hill. This 2012 survey illustrates a region shaped by high-desert ranching and complex drainage patterns, where human presence is marked primarily by isolated outposts. Notable family-named sites like Marty Ranch, Gull Ranch, and Conboys Ranch are connected by rugged local routes like Co HWY-6463. The terrain is characterized by a series of steep drainages, including Deadhorse Canyon, Devil Canyon, and Brady Canyon, which provide a detailed look at the erosional features typical of the Fall River County area. To the north, Line Camp suggests the ongoing importance of range management in this part of the state.
