Horse Prairie Creek meanders through the heart of this high-elevation Montana landscape, serving as the primary drainage for the surrounding terrain. The small settlement of Grant stands at the southern edge of the valley, near the confluence with Barrett Creek. This late-twentieth-century study reveals an intricate network of irrigation systems necessary for high-plains ranching, including the Mansfield Prohosky Ditch, Cross Ranch Ditch, and the Hans Jagger Peterson Ditch. These named waterworks indicate family-managed ranching operations that have shaped the land south of the Rocky Hills.
