2017 Map of Oldham NW

About this map

Coteau des Prairies, a vast upland plateau, defines the landscape of this region on the border of Kingsbury and Miner Counties. The northern portion of the map is dominated by the southern reaches of Lake Thompson, where the terrain transitions into the low-lying Vermillion Flats. This area serves as a critical drainage basin, giving rise to the E Fork Vermillion River which snakes southward through the prairie. The map provides a detailed view of the rural section-line road network, including 220th St marking the county line. For those tracing local history, the Berton Cem stands as a primary landmark in the western townships, situated near the intersection of 436th Ave and 223rd St. The sparse distribution of named features emphasizes the open, agricultural character of the South Dakota plains during this period.
