2015 Map of Herbert Creek SW

About this map

Lake Oahe and the lower reaches of the Cheyenne River define the southeastern corner of this landscape along the border of Ziebach and Dewey Counties. The terrain is characterized by a complex network of drainage systems, most notably Rudy Cr and its northern branch, E Fork Rudy Cr, which carve through the prairie towards the river valley. The map documents a sparsely populated ranching and tribal land environment where topographic features like Talcut Draw and Olson Draw serve as the primary landmarks. Human infrastructure is limited to essential transit corridors, including Bia-9 and various county roads that cross the high ground between the seasonal creek beds and the vast reservoir shoreline.
