About this map

Frenchman Creek carves a significant drainage through this part of the northern Montana plains, joined by a network of seasonal watercourses that define the local topography. This 2020 map of the border between Phillips and Valley Counties illustrates a landscape shaped by intermittent water management, featuring reservoirs such as Morgan Reservoir and Carol Reservoir situated north of the expansive Big Toe Flat.

The area is characterized by a series of deep drainages known locally as coulees, including School Section Coulee, Shed Coulee, and the namesake Coulter Coulee. These features, alongside named landforms like Red Mud Coulee and Bohner Coulee, provide a clear picture of the regional hydrography. Modern access is documented via roads like Frenchman Rd and Genevieve Rd, which connect the scattered agricultural and ranching interests across these township and range divisions.
