Bison Bone Reservoir and a series of smaller impoundments like Pep Reservoir and a Private Reservoir define this stretch of the central Montana plains in Phillips County. The landscape is characterized by a high-density network of seasonal drainages, including the branching headwaters of Dry Fork Creek, Beauchamp Creek, and Trine Creek. These watercourses carve through the terrain, illustrating the critical role of water management in this arid ranching environment.
