About this map

Calamity Ridge and the Cathedral Bluffs dominate this landscape in western Rio Blanco County, where the high desert terrain is carved by a complex network of canyons and draws. This 2019 survey captures the modern geography of the Piceance Basin, an area defined by its deep drainages like Monument Gulch and Trail Canyon. Named features such as The Shoulder and Red Hill serve as distinct navigational markers in a region otherwise characterized by its isolation and dramatic elevation changes.

Water sources are scarce but critical, evidenced by Thompson Spring and the seasonally intermittent reaches of E Fork Greasewood Cr. While the map lacks formal town sites, the infrastructure of the local economy is present through county routes like Co RD 122 and Co RD 103. These roads provide access across a landscape marked by unique local identifiers such as Carls Hole and Shaft Gulch, which reflect the area's history of ranching and land use.
