About this map

Lake Francis Case dominates this landscape along the border of Charles Mix and Gregory Counties, where the modern reservoir has transformed the ancient path of the Missouri River. The terrain is defined by the deep drainage patterns of the Fivemile Cr system to the northeast and the N Fork Whetstone Cr to the southwest, carving through the high plains. While the waters of the dammed Missouri have submerged the low-lying shoreline of the mid-20th century, the upland remains a network of section-line roads and ranching tracks. Local travel is facilitated by Sd-1806 and family-named routes such as Wynia Ranch Rd and Bh Rd, reflecting the sparse but enduring agrarian settlement of this river-bluff region.
