Thunder Basin National Grassland dominates this high-plains landscape in Converse County, where the intricate network of drainage draws and ephemeral creeks reveals a complex watershed. The terrain is defined by several prominent family and descriptive landmarks, such as Pinnacle Rocks and Split Hill, which sit alongside numerous draws including West Fork Rattlesnake Draw and Riehle Draw. Human presence is sparsely marked by cattle-country infrastructure like the Fiddleback Ranch and the managed water of Rat Number 1 Reservoir.
