About this map

The Coteau des Prairies, a vast plateau of glacial deposits, defines the eastern landscape of South Dakota where the Big Sioux River carves a winding path through the prairie. In this section of Moody County, the river’s valley is a central corridor for recreation, now marked by the Jay Heath Canoe & Kayak Trl. Settlement patterns follow a rigid grid of section lines, though the land remains primarily agricultural. Significant for local family historians is the Yeo Cem, a small burial ground situated near the river's bend in the lower portion of the survey. The northern reaches are drained by Medary Cr, which joins the larger watershed amidst a network of county routes and section roads that have structured this rural territory since the initial land surveys.
