Unit 3
MOFFAT
High-desert basins and low ridges spanning northwestern Colorado's sagebrush country.
Hunter's Brief
GMU 3 stretches across Moffat County's expansive sagebrush plateaus and gentle ridges between the Yampa River and Wyoming border. Elevations range from around 5,700 to 7,400 feet—mostly open country with scattered timber and ponderosa pine on higher slopes. A connected network of county roads and two-tracks provides solid access throughout, though the terrain's flatness means finding concentration areas requires understanding water sources and seasonal movement patterns. Limited reliable water demands good reconnaissance before the hunt.

Terrain Deep Dive
Landmarks & Navigation
The Great Divide ridge runs through the unit and provides useful visual reference for orientation and longer-range glassing. Bald Mountain, Sugarloaf Peak, and Boston Hill mark higher points suitable for scanning country. Named drainages—Bald Mountain Draw, Alkali Draw, and Mud Spring Gulch—serve as navigation corridors and likely concentrate animals during dry periods.
Spring Creek and its branches run through central country and represent reliable water references. Hardgrove Rim and Godiva Rim offer vantage points. These features aren't dramatic but provide meaningful landmarks in otherwise subtle terrain.
Elevation & Habitat
Terrain sits entirely in the 5,700 to 7,400-foot band, with most country in the lower-to-middle elevations where sagebrush dominates. Scattered ponderosa and juniper appear on ridges and higher benches, creating a mosaic of open basins and timbered draws. The flatness of the terrain is deceptive—what appears uniform sagebrush from a distance reveals subtle drainages, creek bottoms with willow corridors, and occasional rock outcrops.
This is classic big game transition country where elevation gain is modest but vegetation patterns create distinct habitat zones that concentrate animals seasonally.
Access & Pressure
Over 1,200 miles of roads crisscross the unit—an impressive network for Colorado backcountry. Most are county roads and maintained two-tracks providing good access to nearly all country. This connected road system means hunters can stage easily from multiple directions and many people can access the interior without hiking far.
Pressure follows roads logically—expect crowds near main drainages and water sources, but the unit's sheer size and scattered development mean solitude is achievable by moving away from creek bottoms into exposed sagebrush basins where few hunters venture without water certainty.
Boundaries & Context
GMU 3 occupies the northwestern corner of Colorado in Moffat County, bounded by Wyoming to the north, Highway 13 and county roads to the east, the Yampa River and U.S. 40 to the south, and the Little Snake River to the west. The unit encompasses vast sagebrush-covered basins and gentle ridgetops characteristic of the Colorado-Wyoming high desert transition. Major population centers are distant—Maybell and Sunbeam are small outposts within or near the unit.
This is expansive, relatively undeveloped country with a sparse human footprint outside hunting season.
Water & Drainages
Water scarcity is the defining constraint in this unit. The Yampa River bounds the south and Little Snake River bounds the west, but much of the interior relies on seasonal springs and small creeks. Named springs include Brouse, Iron Springs, Adobe Springs, Omstead, Kelly, Conway, Barber, and Thornburgh—worth locating on maps before hunting.
Spring Creek and its tributaries (West Prong, Timberlake, Sand Creek, Willow Creek) are the main drainage systems, though flow varies seasonally. Summer and early fall require knowledge of active water sources; late season pressure concentrates around reliable springs and creek bottom vegetation.
Hunting Strategy
GMU 3 holds elk, mule and white-tailed deer, pronghorn, moose, and black bear—each using elevation and water patterns predictably. Early season elk use higher sagebrush and ponderosa slopes before migrating to creek bottoms and draws as temperatures drop. Deer follow similar patterns, with mule deer favoring ridges and transitions while white-tailed deer concentrate in willow corridors.
Pronghorn are native to open sagebrush and often visible from distance. Moose are present in limited numbers near reliable water. Success hinges on locating animals near water during dry periods and understanding migration between summer ridges and winter draws.
The straightforward terrain means glassing from high points and methodically hunting drainages are effective—complexity lies in finding active water and reading subtle sign in sagebrush country rather than navigating difficult terrain.
