About this map

Sedlano Cr and Williams Cr define the drainage patterns across this section of the Great Plains, where the border of Jones Co and Lyman Co runs vertically through a landscape organized by the Public Land Survey System. The terrain is characterized by a high concentration of prairie potholes and small seasonal wetlands, which appear as numerous depressions across the higher elevations between the creek valleys. A sparse but regular grid of section-line roads, including 244th St and 248th St, provides access to the expansive agricultural tracts. While there are no major settlements on this sheet, the intersection of routes like Co Rd 59 and 288 Ave indicates the essential connectivity for the rural ranching and farming operations that have shaped this portion of South Dakota for generations.
