2015 Map of Swan Lake

About this map

Coteau des Prairies defines the rolling topography of this northeastern South Dakota landscape, where glacial legacy is evident in the numerous depressions and small water bodies. The survey shows the boundary between Day Co and Clark Co as it crosses a grid of rural section roads including 154th St and 432nd Ave. Notable for genealogists are the isolated burial grounds of Highland Cem and Hosanger Cem, which serve as primary landmarks in this sparsely populated agricultural region. The southern portion of the map is dominated by the waters of Swan Lake, while Mud Lake sits at the far northern edge, illustrating the typical prairie pothole drainage patterns of the region during the early 21st century.
