2021 Map of Antelope Valley

About this map

Coteau des Prairies defines the geography of this northeastern South Dakota landscape, where the plateau's complex glacial topography creates a dense network of seasonal basins and wetlands. The central depression of Antelope Valley serves as a natural corridor between the higher elevations, dominated by Myers Lake and the headwaters of the S Fork Whetstone River. This 2021 survey illustrates a sparse rural settlement pattern, where the township and range grid is etched into the terrain by local routes like Co Hwy 14 and 462nd Ave. For local historians, the Antelope Valley Cem stands as a primary landmark along 151 St, situated near the intersection of several historical township boundaries. The map also clearly delineates the border between Grant Co and Codington Co, showing how county roads like Codington Co 2 integrate into the regional transport network.
