2017 Map of Rat Hole Ridge

About this map

Atchee Ridge and Rat Hole Ridge dominate this high-altitude landscape along the border of Garfield County, Colorado, and Uintah County, Utah. The terrain is characterized by a complex system of drainage and erosion, with numerous named canyons such as Moonshine Canyon, Weatherbee Canyon, and South Rat Hole Canyon cutting through the ridges. This 2017 survey reveals a network of high-desert access routes, including the Lone Spring Ridge Loop and Atchee Ridge Rd, which navigate the steep topography between various water sources like Lone Spring and Bitter Cr. The prevalence of named canyons like Tony Canyon and Fatty Canyon suggest a history of local geographic naming tied to early livestock or exploration routes in this part of the Colorado Plateau.
