Grant and the nearby settlement of Horse Prairie serve as the focal points for this high-altitude cattle ranching landscape in Beaverhead County. The terrain is defined by a sophisticated irrigation network necessary for high-plains agriculture, including the Hans Peterson Ditch, Jagger Ditch, and Paiment Ditch, which redirect water from Horse Prairie Creek and Dunlap Creek. This intricate system of water rights and ranching infrastructure reveals how early 21st-century landowners managed the arid environment below the Rocky Hills.
