2017 Map of Big Stone Lake SW

About this map

The town of Corona anchors the northwestern corner of this 2017 survey, situated near the boundary between Roberts and Grant counties. This agricultural landscape is defined by the winding course of the North Fork Whetstone River, which flows through the eastern half of the quadrangle. The map reveals a highly structured grid of section lines and rural routes, including Co Hwy 2 and Co Hwy 21, which facilitate movement through the farming communities of the Coteau des Prairies region. For those tracing local history or genealogy, the Kilborn Lutheran Cem serves as a significant landmark along 142nd St. The abundance of wetlands and small basins throughout the terrain indicates the glacial legacy of this part of South Dakota, where the interplay of water and elevation continues to shape land use and local development.
