2015 Map of Lone Tree Lake

About this map

Coteau des Prairies defines the elevated landscape of this South Dakota region, where glacial activity left behind a complex network of wetlands and depressions. The map reveals a strictly regulated agrarian layout, with section lines and gravel roads like 150th St and 421st Ave framing the prairie. Historical footprints are preserved at the Saint Ansgaar Cem in the central portion of the quadrangle, serving as a landmark for local family researchers. The southern reaches are characterized by substantial water bodies, most notably Lone Tree Lake, while Mud Cr provides drainage in the north. This survey illustrates the persistence of the section-line road system in maintaining the region's agricultural continuity across the Day and Clark County line.
