About this map

Coteau des Prairies, a vast glacial upland, dominates this landscape in eastern South Dakota at the border of Kingsbury and Miner Counties. The northern portion is marked by the southern reach of Lake Thompson, which transitions into the low-lying Vermillion Flats. The terrain here is defined by subtle elevation changes that direct the drainage toward the E Fork Vermillion River, which meanders through the eastern townships. This rural expanse is organized by a precise grid of section-line roads, including 438th Ave and 220th St. A key point of interest for genealogists and local historians is the Berton Cem located in the southwest, representing one of the few named landmarks in this predominantly agricultural region.
