2016 Map of Marshall SE

About this map

The Coteau des Prairies plateau defines the topography of this corner of Lyon County, where glacial landforms create a complex network of wetlands and small basins. The Cottonwood River meanders across the southern sections of the map, carving a shallow valley through the prairie landscape. To the north, Meadow Creek drains toward the larger river system, while water bodies like Lake Marion and Lake Yankton dot the terrain. The rectangular survey system is clearly visible through a grid of rural roads, including Co Rd 20 and Co Rd 69, which follow section lines established in the 19th century. This 2016 survey illustrates a modern agricultural landscape that remains deeply tied to its glacial geological foundations, preserving the historical drainage patterns and land divisions of southwestern Minnesota.
