The boundary line between Chouteau and Cascade Counties bisects this high plains landscape, where the seasonal waters of Flick Lake and the Twentyeight Mile Spring characterize the local geography. The terrain is defined by deep incisions in the earth, most notably Huntley Coulee and the winding Portage Coulee. These features influenced the development of the rural road network, which includes historic thoroughfares like Dent Bridge Rd and Whitehorn Ln.
