2015 Map of Lonesome Lake

About this map

Coteau des Prairies defines the rolling topography of this northeastern South Dakota landscape, where the headwaters of the Big Sioux River and Indian River carve through the glacial highlands. The map centers on the tri-county junction of Day, Grant, and Codington counties, revealing a strictly organized section-line road grid including 150th St and 152nd St. The namesake Lonesome Lake sits as a primary hydrologic feature in the western half of the quadrangle. For those researching local history or genealogy, the Bergen Cem provides a specific point of interest in the southern portion of the survey, reflecting the rural community's established roots amid the expansive agricultural fields and prairie terrain.
