About this map

The western reaches of Rio Blanco County are defined here by the steep, eroded drainages of the Douglas Cr basin. This 2022 survey illustrates a landscape dominated by the high promontories of the Cathedral Bluffs and the prominent Big Ridge to the north. These geological features create a complex network of seasonal watercourses, most notably Philadelphia Cr, which branches into its Left Fork Philadelphia Cr and Right Fork Philadelphia Cr.

Modern access is limited to unpaved routes like Bench Rd and Co Rd 128, tracing the high ground between canyons. The map preserves local topographic naming conventions with numerous family-named or descriptive draws, such as Vandamore Draw, McDowell Gulch, and the neighboring Big Bull Draw and Little Bull Draw. This is a portrait of high-desert terrain where the land's utility is tied directly to the drainage patterns of Cow Canyon and Calf Canyon.
