2017 Map of Lake Madison SW

About this map

Coteau des Prairies, the vast upland plateau of eastern South Dakota, defines the undulating landscape of this 2017 survey. The drainage of the E Fork Vermillion River cuts through the western sections of the map, while N Buffalo Cr appears in the northeast. This rural landscape is marked by the meeting points of Lake, McCook, and Minnehaha counties, reflecting a late-20th-century agricultural pattern of section-line roads like Valley Rd and Co HWY 56.
