2021 Map of Vivian NW

About this map

Fort Pierre National Grassland dominates the northern horizon of this central South Dakota landscape, where the prairie is defined by the winding drainages of the N Fork Medicine Cr. This 2021 survey reveals a vast network of section-line roads and local thoroughfares like 283rd Ave and 236th St that partition the open range into traditional grid-based grazing and agricultural tracts. The terrain is marked by the distinct draws and coulees feeding into Medicine Cr in the south, illustrating the subtle but essential water management of the High Plains. While human structures are sparse, the presence of various county routes, including Co Rd S 10, indicates the ongoing importance of road connectivity for ranching operations and public land access in this remote portion of Jones County.
