About this map

Glacial potholes and prairie wetlands define the topography of this Edmunds County landscape, as mapped during the early 21st century. The section lines of the Public Land Survey System dictate the movement of local traffic, with unpaved routes like 336th Ave and 338th Ave crossing an expansive network of East River prairie basins. While most thoroughfares follow the rigid 1-mile grid system, including 134th St and 131st St, the southern portion of the quadrangle shows minor deviations with named local connectors such as Valley Rd and Glover Rd. This pattern of township and range divisions, specifically within t123n r72w and t123n r71w, illustrates the enduring influence of the 19th-century homesteading layout on modern South Dakota agricultural land use.
