About this map

The Coteau des Prairies plateau shapes this region of South Dakota, where the landscape is defined by its glacial heritage and numerous prairie potholes. In the northwestern corner, Belleview Cem stands as a focal point for genealogical research among the section lines of Adams Township. The area is characterized by an extensive network of wetlands and water bodies, including McCart Slough in the north and the larger Silver Lake and Otter Lake to the southeast. The drainage of the land is managed by the E Fork Vermillion River and the meandering Little Vermillion River, which passes through distinctive formations like The Horseshoe. This 2017 survey documents the modern layout of rural infrastructure, tracing the precise alignment of local thoroughfares such as Co HWY 8 and numerous numbered section roads.
