2017 Map of Antelope Valley

About this map

The Coteau des Prairies plateau dominates this northeastern South Dakota landscape, characterized by a high concentration of small wetlands and glacial depressions. Within this undulating terrain, the Antelope Valley and its namesake Antelope Valley Cem serve as primary landmarks for local history researchers and genealogists tracing families in this rural corridor. The map reveals a strictly rectangular grid of county roads, such as Co HWY 14 and Co HWY 7, which navigate around natural water features like Myers Lake and the Twin Lakes at the northern boundary. Straddling the line between Grant and Codington counties, the area's agricultural layout is defined by the Public Land Survey System, with township and range lines like t120n r51w providing the framework for the region's isolated farmsteads and field patterns.
