Thunder Basin National Grassland dominates the southern reaches of this landscape in Campbell County, where the high plains meet complex drainage systems. The terrain is defined by prominent landmarks such as Bowman Hill and the weathered formations of the Duck Creek Breaks. This map documents a ranching-heavy geography where water management is critical, evidenced by a series of named catchments including McConnell Number 1 Reservoir, Bunker Butte Reservoir, and Tony Reservoir. Connectivity in this open country relies on a few primary arteries like Rocky Point Rd and Parks Rd. The map also captures the headwaters of several drainages, including Dry Cr and N Fork Duck Cr, which carve through the Eightyfive Divide and the area surrounding Squaw Butte.
