2017 Map of South of Pierre

About this map

Fort Pierre National Grassland dominates the central portion of this landscape at the intersection of Jones, Stanley, and Lyman counties. The terrain is defined by a dendritic drainage network, with the headwaters and winding paths of Antelope Cr and Gray Blanket Cr cutting through the prairie. This 2017 survey illustrates the sparse, grid-based infrastructure of the high plains, where long stretches of unpaved roads like Warcreek Rd and 219th St connect remote sections of the public land system. Significant local transport corridors include Co Hwy 20 and 291st Ave, providing a clear record of the modern rural road network in a region where natural watercourses like Cedar Cr still dictate the rhythm of the landscape.
