2021 Map of Rousseau Creek NW

About this map

Fishgut Cr and the headwaters of Hosupa Cr define the western reaches of this Dewey County landscape, where the high prairie begins its descent toward the Missouri River breaks. The drainage network is prominent, featuring the winding paths of W Br Rousseau Cr and E Br Rousseau Cr as they cut through the township divisions of t12n r26e and t12n r27e. This modern survey by the U.S. Geological Survey reflects the open, rural character of the Cheyenne River Reservation, where transportation is centered on routes like Armstrong Co Rd and BIA Hwy 8. The map provides a clear view of the topographical relief and the intricate seasonal waterways, including Fox Cr in the northeast, which are critical to understanding the local geography and land use in this part of South Dakota.
