Colorado Unit 21 Description

Unit 21 Located in Rio Blanco and Garfield Counties bounded on the North by the White River; on the East by Monument Gulch, Colorado 64, Monument Gulch Rd. and Rio Blanco CRs 103 & 26; on the South by Douglas Creek-Roan Creek divide, Douglas Creek-Salt Creeks divide, Evacuation Creek-Salt Creeks divide and Bitter Creek- West Salt Creek divide; on the West by the Utah state line.

GMU 21 Pinyon-juniper, with pockets of sagebrush, cover most of the areas at lower elevations. Higher elevations are characterized by sagebrush interspersed with aspen stands and some dark timber. Terrain varies from rolling sagebrush to steep-sided canyons. Some areas are steep & rugged, especially in southern portion. Rains bring  muddy roads. High elevation snows make roads impassible without chains. 75% of area is BLM land. There are remote hunting areas accessible by foot, horseback or ATV. Get maps and study BLM access points. Weather is generally mild. Hunting ranges from fair to good in the Bookcliffs and Piceance units. Deer are well-distributed in the northern portion after mid October. Concentrate on higher elevations in early seasons. If the weather is dry, you’ll need to do a lot of walking and looking. Good snows will move the herds to lower elevations to the north and to the south. Hunt high early, low later. Cathedral Rim has some big bucks, but tough terrain. Little Hills and Dry Fork of Piceance is better late. GMU 21 is managed as a quality deer unit. Good cow hunting opportunities. The best hunting is in remote areas, mostly at high elevations, where the elk tend to hold up in pockets of green timber and aspen. Check out the Texas Mountain area and Rat Hole Ridge. Hunting pressure will push some bulls into the large expanses of pinyon-juniper. If snow and hunting pressure are sufficient, some elk will move into the Little Hills and Dry Fork area of Piceance later in the seasons.
