Flat Tops Wilderness and the Routt National Forest define this high-altitude landscape along the border of Routt and Rio Blanco counties. The area is characterized by an intricate network of water management features necessary for high-country ranching and agriculture, including the Trout Creek School Ditch, Last Chance Ditch, and Alpha Ditch. These diversions draw from numerous water bodies such as Crosho Lake and Allen Basin Reservoir to support the lower elevations. The terrain is marked by prominent elevations like Pinnacle Peak and Bellyache Mountain, with the Flat Tops plateau dominating the southern portion of the survey. Significant water storage is evident at Chapman Reservoir and Killarney Reservoir, while a Scenic Byway provides modern access through the northeastern mountain passes.
