Unit 441, Colorado

Elevation ranges from approximately 6,400 feet along the Yampa River valley floor to 10,879 feet at Sand Mountain and comparable peaks in the Elkhead Mountains. The unit covers roughly 194 square miles (about 124,000 acres). Topography is a mix of rolling sage-covered foothills in the west and north, steeper ridge-and-canyon country through the mid-unit, and forested mountain terrain in the eastern two-thirds within Routt National Forest. Secondary roads typically require four-wheel drive, especially at higher elevations.

Unit boundaries: north by USFS Road 42; east by the Elkhead Creek-Elk River divide and Wolf Creek; south by U.S. Highway 40; west by Elkhead Creek. US Highway 40 (Craig to Steamboat Springs) is the primary paved corridor along the southern boundary. The eastern two-thirds of the unit lies within Routt National Forest, administered by the Hahns Peak/Bears Ears Ranger District (office in Steamboat Springs, 970-870-2299). The California Park/Black Mountain area on the west side of the Routt NF provides trailhead access via Adams Creek Trailhead (connecting to the Bears Ears trail system #1144). Freeman Reservoir campground and boat ramp provide base-camp options. The Bureau of Land Management Little Snake Field Office (455 Emerson St, Craig, CO; 970-826-5000) administers scattered BLM parcels in Moffat and Routt counties. Land ownership is approximately 32% public (19% USFS, 10% State, 1% BLM) and 68% private — most non-forest land is privately held agricultural and ranch property, accessible only on a fee or permission basis. Four-wheel drive is typically required on secondary forest roads. Jimmy Dunn Gulch recreation area requires hunter check-in. Nearby services in Craig (west) and Steamboat Springs (east); Elkhead Reservoir State Park has approximately 15 campsites; Yampa River State Park accommodates RVs.

Lower-elevation riparian corridors along the Yampa River and Elkhead Creek support cottonwoods, shrubs, and adjacent sagebrush flats. Mid-elevation slopes carry sagebrush, mountain shrub, oakbrush, grass, and scattered ponderosa pine. Higher elevations within Routt National Forest transition to aspen parks, spruce-fir, and additional ponderosa pine with open meadow parks. The unit also contains dryland alfalfa and irrigated hay on private valley land, which attracts pronghorn and wintering deer and elk.

The unit hosts one of the highest elk densities in Colorado as part of the Bears Ears Herd (E-2). Annual survey flights classified 10,203 elk across the E-2 area (GMUs 2, 3, 4, 5, 301, and 441). After the severe 2022-23 winter reduced populations in some northern Craig areas by roughly 50%, calf recruitment recovered steadily: fewer than 10 spikes per 100 cows in 2023, 14 in 2024, and 16 in 2025. By 2026 the herd returned to within population objective range for the first time since the die-off, prompting CPW to significantly increase antlerless elk licenses while returning 2nd and 3rd rifle bull tags to OTC. Elk summer at higher Routt NF elevations and migrate to lower sagebrush and valley habitat as weather progresses; bulls on public land are predominantly younger-age class animals, with more mature bulls retreating to private or remote terrain under pressure. Mule deer occupy the unit year-round with highest concentrations in the western portions; the herd experienced similar winter-related declines and is rebuilding. Pronghorn use rolling sagebrush and open ranch land throughout the valley floors; the pronghorn population was severely impacted by the 2022-23 winter with male license cuts of over 74%, and numbers are gradually recovering toward 2026. Black bear and mountain lion are present in forested portions of the unit. Wild turkey also occur in the unit.
