About this map

Rat Hole Ridge and Lone Spring Ridge dominate this high-desert landscape along the border of Utah and Colorado. The map documents a complex drainage network where deep canyons such as Moonshine Canyon, Weatherbee Canyon, and South Rat Hole Canyon carve through the high plateaus. Human presence is marked primarily by high-altitude access routes including the Atchee Ridge Rd and the Lone Spring Ridge Loop, which provide passage through this dissected terrain.

Water sources are scarce but critical, centered on the eponymous Lone Spring and the seasonal flows of Bitter Cr and Whiskey Cr. The nomenclature of the area reflects its remote character, with landmarks such as Dick Canyon, Tony Canyon, and Fatty Canyon suggesting the personal histories of the early ranchers or prospectors who navigated these ridges. This survey provides a clear view of the territorial divide between Uintah County, Utah and Garfield County, Colorado.
