The Sacagawea River winds through this section of Petroleum County, cutting a complex drainage pattern across the high plains. This modern survey illustrates the intersection of public land management and natural hydrography, specifically where the Charles M Russell National Wildlife Refuge occupies the eastern edge of the quadrangle. The terrain is defined by a network of seasonal watercourses and coulees, including Hay Coulee and Carpenter Coulee in the north, which feed into the primary river valley.
