About this map

Warnes Slough defines the northwestern reaches of this prairie landscape, serving as a primary hydrological landmark in a region characterized by scattered wetlands and seasonal basins. Located on the transition between the Missouri Plateau and the glaciated plains, the terrain is structured by a methodical grid of section lines and rural corridors like 297th Ave and Co Rd 207. The map illustrates the sparsely populated border where Sully Co Hughes Co meet, a boundary that marks the divide between northern and southern drainage patterns in this part of South Dakota. The land-use pattern here remains centered on large-scale agricultural blocks, with the 2021 survey recording the contemporary placement of local access roads such as 196th St and 301st Ave that facilitate movement across the open plains.
