About this map

The Missouri River cuts a wide, meandering path through this portion of the Montana plains, defining the boundary between Roosevelt and Richland counties. The landscape is characterized by a series of significant drainage features, including the eponymous Cedar Coulee and Star Coulee, which create a complex network of breaks leading down to the river valley. These landforms reveal the erosional history of the region, where seasonal waterways have carved deep into the prairie.

In the northeast, Harmon Reservoir provides a managed water source for this semi-arid environment. The mapping of Deep Coulee, Rocky Point Coulee, and Wells Coulee highlights the importance of topographic naming in a sparsely populated region where such landmarks are essential for navigation. Local infrastructure is represented by rural roads like Co Rd 342 and Co Rd 147, which connect the disparate sections of this high plains country.
