Thunder Basin National Grassland dominates this high-plains landscape, where the Cheyenne River Divide serves as a critical geographic marker between drainage systems. The terrain is defined by a network of seasonal watercourses and ridges, including the appropriately named Coal Draw and the stark topography of Dilts Flat. Evidence of ranching and water management in this arid environment is found in features like the Bear Cr Number 1 Reservoir and Reynolds Reservoir, which capture runoff from the N Fork Bear Cr and S Fork Bear Cr. The sparse road network, including Co Rd 34 and Jennie Trail Rd, traces the movement patterns of land managers and ranchers across these expansive public lands in Converse County.
