Upper Missouri River Breaks National Monument defines the southern portion of this landscape in Blaine County, where the terrain breaks away into complex drainage networks. This modern survey illustrates a high-plains environment dominated by episodic watercourses and topographic benches. Cromley Bench stands out as a prominent landform, flanked by numerous seasonal coulees including Tin Cup Coulee, Spring Coulee, and West Fork Jacks Coulee.
