2021 Map of Hamill NW

About this map

White River carves a sweeping path across the northern boundary of this South Dakota landscape, defining the jagged border shared between Lyman Co and Tripp Co. The terrain is characterized by a dense network of coulees and ridges that drain toward the main river valley via No Moccasin Cr and Black Dog Cr. This 2021 survey illustrates a sparse, rural infrastructure where the section lines of the Public Land Survey System dictate the placement of local thoroughfares like 324th Ave and 259th St. The transition from the high prairie down to the river bottoms is marked by steep elevation changes, preserved here in a snapshot of modern ranching country. Local transit is served by a grid of named routes including Deer Valley Rd and Brule Rd, which navigate the undulating topography of the northern Great Plains.
