2024 Map of Coulter Coulee

About this map

Frenchman Creek meanders through this portion of the northern Montana plains, defining a landscape shaped by seasonal water management and the rugged drainage systems of the Missouri River basin. The map reveals a sparse network of ranching roads, including Frenchman Rd and Upper Frenchman Rd, which navigate the complex topography of unnamed breaks and high flats. Significant water storage is represented by Morgan Reservoir and Carol Reservoir, critical infrastructure in this arid environment. Distinctive local landmarks like Big Toe Flat and the deep incisions of Red Mud Coulee and Shed Coulee illustrate the erosive power of the elements in Valley County. The transition across the Phillips County and Valley County line highlights the administrative boundaries of this vast grazing territory.
