2015 Map of Sansarc NE

About this map

Cheyenne River and the expansive Lake Oahe define the northern border of this South Dakota landscape, marking the transition between Dewey and Stanley counties. The terrain is characterized by broad alluvial benches such as Kid Rich Flats, Marion Flats, and Mississippi Flats, which sit above the winding drainage of Foster Cr. For those researching local history or genealogy, the map identifies specific burial sites including Walking Horse Cem overlooking the river and Lindsay Cem further south. The map's grid of section lines and gravel roads, such as Fosters Bay Rd and Mule Deer Rd, illustrates the expansive rural layout of the region in the early 21st century, where the economy remains tied to the vast open spaces of the Missouri River reservoir system.
