Morony Dam anchors this landscape, where the Missouri River cuts deep through the high plains of northern Montana. The terrain is defined by a network of drainage features including Blackfeet Gulch, Portage Coulee, and Widow Coulee, reflecting the erosion patterns common to this reach of the river. The small settlement of Salem sits on the southern plateau, connected to the river valley by an established network of rural routes such as Salem Rd and Bickford Rd.
