The Missouri River carves a deep, winding path through the heart of the northern Montana plains, defining the boundary between Cascade Co and Chouteau Co. This landscape is characterized by its dramatic drainage patterns, where long erosional features like Cherry Coulee and Black Coulee stretch across the high benchlands toward the river valley. To the south, Highwood Creek and its various tributaries, including Tueveerson Coulee and Widow Coulee, create a complex network of seasonal watercourses.
