2015 Map of South of Pierre

About this map

Ft. Pierre National Grassland dominates the central portion of this landscape where the boundaries of Stanley, Lyman, and Jones counties converge. This 2015 survey reveals a terrain defined by the drainage patterns of Antelope Cr and Gray Blanket Cr, which carve through the high plains south of the Missouri River. The map captures the organized section lines of the Public Land Survey System, specifically t109n r79w and t108n r79w, illustrating how the ranching and conservation lands are partitioned. Transportation is sparse, primarily confined to Warcreek Rd and Co Hwy 20, reflecting the open and undeveloped nature of this protected prairie environment. To the southeast, the headwaters of Cedar Cr emerge, adding further topographical variation to this expansive grassland region.
