2021 Map of Lyonville

About this map

Lyonville sits in the southern portion of this landscape, positioned along the survey line in Brule County. The terrain is defined by a sparse network of section-line roads and the winding paths of intermittent waterways like Smith Cr and Crow Cr. The area is a nexus of three South Dakota counties — Buffalo, Jerauld, and Brule — with boundaries clearly delineated as they bisect the prairie. This 2021 update from the U.S. Geological Survey shows the modern placement of local thoroughfares such as 362nd Ave and Prairie Ln. The mapping reflects the enduring Public Land Survey System grid, which continues to dictate the orientation of farms and property boundaries across this section of the Great Plains.
