About this map

Coteau des Prairies, a vast glacial plateau, defines the landscape of this portion of Miner County. The topography is characterized by a high density of semi-permanent wetlands and small glacial lakes, reflecting the region's terminal moraine geology. The Little Vermillion River and E Fork Vermillion River drain these uplands, winding through a grid of section-line roads such as 438th Ave and Co Hwy 8. Human imprint is primarily agricultural and commemorative, centered on the Belleview Cem in the northwestern quadrant. Significant water bodies including Silver Lake, Otter Lake, and Pedley Lake are interspersed with numerous sloughs like McCart Slough and Wombacker Slough, illustrating the complex drainage patterns of the prairie pothole region.
