About this map

The Coteau des Prairies upland plateau dominates this Lyon County landscape, where the glacial landforms dictate the drainage patterns of the region. The Cottonwood River meanders across the lower elevations, joined by smaller tributaries like Meadow Cr that flow through the agricultural grid. This area of Southwest Minnesota is characterized by its numerous glacial depressions, including Lake Marion in the northwest and Lake Yankton to the southwest. The mapping of the local section-line road network, including Co Hwy-20 and Us-59, provides a clear view of the rural township structure that has defined the region's development since the late 19th century.
