Horse Prairie dominates the southern reaches of this landscape, reflecting the broad open-range geography of Beaverhead County. The terrain is defined by a series of expansive flats, notably Poverty Flats and Coyote Flats, which give way to the prominent rise of Bachelor Mountain in the east. Water management is a central feature of the local economy and geography, evidenced by the intricate system of irrigation channels such as the Mansfield-Prohosky Ditch and Pierce Ditch that draw from Horse Prairie Cr.
