Unit 301, Colorado

GMU 301 spans roughly 367 square miles (approximately 234,919 acres) in the lower Yampa country of Moffat County. Elevations range from approximately 6,000 feet at the valley floors to about 8,500 feet at the higher ridgelines. The landscape is composed of rocky hillsides, cut ravines, open ridges, and shrub-covered flats. Terrain is generally moderate in slope — public land within the unit averages 80% or less in gradient — and 4WD is typically unnecessary on most established routes. Later rifle seasons can bring moderate snow and near-zero temperatures.

GMU 301 is predominantly private land — approximately 85% private and 15% public (roughly 11% BLM and 4% State Land Board), confirmed by HuntScore and corroborated by cohunter.com noting that neighboring Lower Yampa units (GMU 3, 11, 211) are 70% public while GMU 301 is the private-land outlier. The unit is bounded by Colorado Highway 13/789 on the east (the Craig-to-Baggs corridor), the Yampa River on the south, Moffat County Road 17 on the west, and Moffat County Roads 5, 158, 3, and 108 on the north. The dominant federal agency is the BLM Little Snake Field Office (455 Emerson Street, Craig, CO 81625; 970-826-5000), which administers approximately 1.3 million acres across Moffat, Routt, and Rio Blanco counties. Craig (U.S. Highway 40) is the main service hub roughly at the eastern boundary. Public BLM parcels are scattered in a checkerboard pattern among private ranch holdings; hunters must verify land status before accessing any parcel. No designated wilderness areas fall within this unit. Access is generally straightforward on county roads and BLM two-tracks, but many of the best elk habitats are on private ground, and hunting pressure on public parcels is described as heavy throughout the season. No documented seasonal road closures were found for BLM ground within the unit boundaries, though spring mud closures on unimproved roads are common in this region.

Lower elevations are dominated by sagebrush steppe, which constitutes approximately 67% of the unit's overall cover. Upper elevations transition into pinyon-juniper woodland interspersed with mountain shrub communities (oakbrush and serviceberry). Riparian corridors follow the Yampa River along the unit's southern boundary. The semi-arid character throughout makes the unit attractive winter range for migratory big game moving down from higher surrounding units.

GMU 301 supports a large resident elk herd described by CPW-cited sources as occupying all available habitat in the unit. Elk that summer at higher elevations in adjacent units move into unit 301 as winter approaches, concentrating on lower sagebrush and pinyon-juniper ranges along the Yampa valley. Mule deer inhabit the unit year-round, with concentration highest in mountain shrub and pinyon-juniper breaks. Pronghorn use the semi-arid sagebrush flats throughout the unit. Black bear are present, tracking food sources through the fall. Mountain lion inhabit rocky canyon country and prey on deer and elk. Turkey are present in the unit. No moose, bighorn sheep, or white-tailed deer populations are documented for this unit in available sources. The Yampa River riparian corridor provides important movement habitat along the southern boundary.
