The Sacagawea River winds through the heart of this central Montana landscape, defining the topography of the region where the Fergus Co and Petroleum Co line meets. The terrain is characterized by a dense network of drainages and seasonal watercourses, including the descriptive Whiskey Coulee and Rasmussen Coulee. These features represent the complex erosion patterns common to this part of the plains, where the land falls away from high points like Dovetail Butte into deep, narrow valleys.
