The Marias River carves a deep, winding path through this portion of Chouteau County, creating a complex network of eroded drainage features across the Montana plains. The terrain is defined by dramatic elevation changes where the river has cut into the surrounding plateau, forming prominent breaks like Sheep Coulee and Slide Out Coulee. These geographical features influenced the placement of local transport routes, which largely skirt the edges of the river breaks.
