2017 Map of Lonesome Lake

About this map

Coteau des Prairies, a vast highland plateau, defines the landscape of this region where three South Dakota counties converge. The glacial topography is marked by significant hydrological features, most notably the Big Sioux River and the Indian River as they wind through the agricultural sections of t121n r52w and t120n r52w. Near the center of the map, Lonesome Lake sits as a prominent natural landmark amidst the section-line road grid. For those researching local heritage, the inclusion of Bergen Cem south of Co HWY 14 provides a specific point of interest for genealogical study within this prairie landscape. The map meticulously documents the transition of county lines between Day, Grant, and Codington counties.
