Big Porcupine Cr winds through the heart of this Rosebud County landscape, joined by its northern and southern tributaries, E Blacktail Cr and W Blacktail Cr. This 2020 survey illustrates a sparsely settled region of Montana defined by a complex network of coulees, which serve as natural drainages for the upland terrain. These features, including Badland Coulee, Nelson Coulee, Sun Coulee, and McGraw Coulee, underscore the geological character of the drainage basin.
