About this map

The prairie landscape of Harding and Perkins counties is defined by the winding drainages of the Missouri Plateau, where intermittent watercourses like Antelope Cr and Ash Cr carve through the open range. This 2021 survey illustrates the vast sections of the Public Land Survey System, specifically within t16n r10e and surrounding townships, showing a region where settlement is sparse and dictated by the availability of water and the orientation of section-line roads.

A network of local routes, including Zeona Rd and Marty Rd, provides the primary infrastructure for this ranching country. The inclusion of Sheep Cr in the southern portion of the map further emphasizes the importance of these seasonal waterways in a semi-arid environment. For those studying the recent geography of the South Dakota plains, the map offers a clear look at the modern land divisions and access points that define life in the northwestern corner of the state.
