Unit 22
RIO BLANCO/GARFIELD
Rolling sagebrush ridges and creek drainages between the White River valleys of northwestern Colorado.
Hunter's Brief
Unit 22 spans rolling terrain dotted with ridges, gulches, and scattered timber across the Piceance Creek Basin country. Elevations climb from lower valleys into moderate foothills with ponderosa and mixed conifer stands. Road access is fair but spread across the unit—expect a mix of county roads and rougher routes. Water is limited to springs and creeks scattered throughout the drainages, requiring prior scouting. This size unit offers room to find solitude, though hunters should plan water strategy carefully and be prepared for variable terrain.

Terrain Deep Dive
Landmarks & Navigation
Several ridgelines serve as natural travel corridors and glassing platforms: Fourteenmile Ridge, Calamity Ridge, and Trail Ridge are prominent north-south features offering elevation gain and vantage points. Blair Mesa and Segar Mountain provide landmark reference points for navigation. The Piceance Creek Basin itself anchors the unit geographically.
Major drainages—Duck Creek, Bitter Creek, Thirteenmile Creek—form the skeleton of the terrain and offer water sources as you descend from ridges. Black Cabin Point and the Dudley Bluffs provide visual breaks in the landscape useful for navigation and orientation.
Elevation & Habitat
The unit spans from lower valleys around 5,400 feet up to ridgetops above 8,800 feet, with most terrain clustered in the 6,500 to 8,000-foot band. Lower elevations feature sagebrush flats and grasslands typical of the Colorado Plateau transition zone. Mid-elevations transition into ponderosa pine and mixed conifer stands with scattered aspen.
Higher ridges support denser timber interspersed with meadows and parks. The moderate forest coverage means relatively open country between drainage systems—good for glassing but requiring strategy in timber breaks where animals seek refuge.
Access & Pressure
Nearly 850 miles of roads cross the unit, though they're spread across its vast area—density is moderate rather than concentrated. County roads provide fair access to various ridges and drainages, but some routes deteriorate seasonally. Major highways don't cross through, so approach typically comes from the unit's edges.
The fair accessibility combined with size means pressure distributes unevenly—roads near boundaries get hunted, but terrain deeper into the unit sees less traffic. Expect to encounter other hunters during seasons, but also significant country where you can move without seeing people if you venture away from road corridors.
Boundaries & Context
Unit 22 occupies the Piceance Creek Basin across Rio Blanco and Garfield Counties in northwestern Colorado. The White River forms its northern boundary, while Colorado 13 marks the eastern edge. The unit runs south to the White River-Colorado River divide and west to a mix of county roads and Monument Gulch.
This positioning places it between two major river systems, creating a landscape of interconnected drainages and ridgelines. The terrain rolls across roughly 1,300 square miles of mixed public and private land, with the public portions comprising most of the huntable area.
Water & Drainages
Water is scattered but present throughout the unit's drainage system. Springs—including East Fork, Maverick, Bragg, and Dark Canyon—dot the higher country and ridgetops but require knowledge of their locations. Creeks like Duck, Bitter, and Thirteenmile flow through major drainages but may run intermittently depending on season.
Several reservoirs (West Miller, Pitcairn, Tatum) exist but aren't uniformly distributed. The limited overall water availability means successful hunting requires either proximity to reliable springs or planning routes along major creeks. Early and late season can see springs diminish or dry entirely.
Hunting Strategy
Unit 22 holds elk, mule deer, white-tailed deer, pronghorn, moose, bear, and mountain lion historically. Elk use the higher ridges and timber through fall and rut season before dropping to lower sagebrush valleys in winter. Mule deer frequent the transition zones between sagebrush and timber, using ridges for security and valleys for food.
Pronghorn inhabit open sagebrush flats at lower elevations. Early season rewards high-country ridge hunting; mid-season offers rut activity in timber breaks; late season pushes animals downslope toward sagebrush. Water scarcity makes spring locations and major creeks focal points.
The rolling terrain rewards glassing from ridges but demands patience navigating between vantage points.
