Upper Missouri River Breaks National Monument dominates the southeastern quadrant of this Fergus County landscape, where the breaks descend toward the Missouri River drainage. The area is defined by its complex drainage network, characterized by seasonal coulees including Sawmill Coulee and Murphy Coulee that carve through the high plains. Vital water sources in this arid environment are identified at Sulphur Spring and Bakers Spring, historical points of interest for early cattlemen and travelers navigating the central Montana ranges.
