2016 Map of Dismal Swamp

About this map

Glacial depressions and marshlands dominate this Big Stone County landscape, where the namesake Dismal Swamp lies in the northeastern reaches. The area is defined by its complex hydrology, featuring numerous named basins such as Olson Lake and Bentsen Lake, alongside ephemeral features like Lone Tree Lakebed. Human settlement is sparse and primarily agricultural, organized along a rigid grid of county roads and avenues. Near the center of the sheet, the Maple Cem stands as a quiet landmark amidst the surrounding fields. The transition between permanent water and seasonal wetlands is evident in features like Karl Slough and Hanson Slough, illustrating the delicate water table of western Minnesota. This terrain reflects a rural economy reliant on careful water management and the maintenance of backroads, including segments designated as Minimum Maintance Rd.
