1970 Map of Lonesome Lake

About this map

The Big Sioux River and the Indian River wind through this prairie landscape at the intersection of Grant, Day, and Codington counties. The terrain is organized by the rural townships of Blooming Valley, Germantown, Lura, Dexter, and Egeland, reflecting the geometric grid of 1970s South Dakota agriculture. While the land is primarily characterized by small drainage basins and glacial depressions, the Central Point National Wildlife Management Area in the northwest corner preserves a more primitive character of the plains.
