2021 Map of Lake Madison SW

About this map

Coteau des Prairies, a vast glacial plateau, dominates this portion of the South Dakota landscape where the Lake Co McCook Co line divides the terrain. The map documents a predominantly rural agricultural layout, defined by a grid of section lines and county highways like Co Hwy 58 and Co Hwy 35. For local historians and genealogists, the placement of several burial sites provides significant research value, including the Ramsey Pioneer Cem, the Ramsey Cem further south, and the Saint Peter Lutheran Cem near the northern boundary. Water features are concentrated in the eastern and western sections, notably the winding E Fork Vermillion River and the isolated Island Lake near the McCook Co Minnehaha Co border.
