Elk Hunting in Unit 1

Unit 1 sits in the far northwest corner of Colorado in Moffat County, encompassing the Browns Park National Wildlife Refuge and Cold Springs Mountain. This remote trophy unit near Dinosaur offers roughly 72% public land across arid sagebrush benches, cottonwood river bottoms, and piney ridgelines that harbor a limited but high-quality elk herd.

Where to Find Elk in Unit 1

Elk in Unit 1 use the diverse terrain of Browns Park and the surrounding Cold Springs Mountain area, shifting between river bottoms and higher ridges with the seasons.

Archery Season (August-September)

During early archery season, bulls hold on the timbered north slopes of Cold Springs Mountain above 7,500 feet. Focus on seeps and wallows in the pinyon-juniper transition where morning thermals funnel scent uphill. The Green River corridor draws elk to water at dawn and dusk.

Rifle Season (October-November)

Once rifle pressure builds, elk drop into the thick cottonwood bottoms along the Green River and the brush-choked draws south of Browns Park NWR. Hunters who work the pinyon ridges between Lodore Canyon and Cold Springs Mountain find elk bedded in scattered timber pockets.

Water and Feed

Elk in this unit depend on the Green River, Vermillion Creek, and scattered stock ponds across the BLM sagebrush flats. During dry autumns, the few perennial springs on Cold Springs Mountain become critical congregation points.

Frequently Asked Questions

How many preference points do I need for Unit 1 elk?
Unit 1 elk draw odds vary by weapon type. First-choice rifle tags typically need 10-16 points for residents, with non-residents requiring more. Check the CPW draw statistics for the most current point requirements.
What is the best season to hunt elk in Unit 1?
Archery season offers the best bugling action in September, while second and third rifle seasons in October provide the highest harvest rates. Late season can be productive if snow pushes elk to lower elevations in the Mt Zirkel Wilderness area.
Is Unit 1 good for a DIY elk hunt?
Yes. With 72% public land in the Routt National Forest, Unit 1 supports DIY hunts. Success requires physical fitness, pre-season scouting, and willingness to get away from roads into the steep alpine basins, dense spruce-fir timber, aspen groves.
When is the best time to hunt mule deer in Unit 1?
The November rut during fourth rifle season typically produces the best buck movement. Early rifle seasons offer less competition. Archery hunters find good opportunity in September before pressure builds across the Mt Zirkel Wilderness area.
What kind of bucks can I expect in Unit 1?
Trophy quality is above average for Colorado. Most harvested bucks are 3x3 to 4x4 class, with occasional larger bucks taken by hunters working the remote areas of the steep alpine basins, dense spruce-fir timber, aspen groves.
How much public land is in Unit 1 for deer hunting?
Approximately 72% of Unit 1 is publicly accessible through Routt National Forest and BLM lands. Check the CPW atlas and a GPS mapping app for exact boundaries before hunting.
How do I access public land for pronghorn in Unit 1?
Public land in Unit 1 is primarily Routt National Forest land. Use BLM and CPW maps to identify accessible parcels near Steamboat Springs. Some of the best pronghorn habitat crosses private land, so identify public access points before your hunt.
What is the best tactic for pronghorn in Unit 1?
Water hole ambushes are the most reliable method. Set up a blind near an active stock tank or spring on the steep alpine basins, dense spruce-fir timber, aspen groves and wait for herds to come in. Spot-and-stalk works with patience and terrain features for cover.
Are moose common in Unit 1?
Unit 1 has a small but established Shiras moose population concentrated in willow bottoms. It is not a high-density moose unit, but a hunter who scouts can reliably locate bulls.
How hard is a Unit 1 moose tag to draw?
Unit 1 bull moose tags typically require 18 or more preference points for residents, and cow tags draw with fewer. Check current CPW draw statistics for exact values.
Is Unit 1 black bear draw-only?
Some hunt codes in Unit 1 are limited draw; others may be OTC depending on season and weapon. Check current CPW regulations before applying or purchasing a tag.
When is peak bear activity in Unit 1?
Late August through early October is peak, when bears are in hyperphagia feeding on berries and plums in the pinyon-juniper draws before denning.
How remote is Unit 1 for bear hunting?
Unit 1 is one of Colorado's most remote GMUs, requiring long drives on rough county roads from Maybell or Craig. Plan for self-sufficient camps with extra fuel and water.
How competitive is the draw for Unit 1 black bear?
Unit 1 black bear draw competitiveness depends on the specific hunt code (weapon type, season, sex restriction). With approximately 3 applicants per year, check CPW's Draw Odds statistics for current point requirements by hunt code.

The atlas shows BLM, USFS, State Land Board, and private land boundaries — essential for planning legal access to hunting areas.
When is the best time of day to hunt black bears in Unit 1?
Black bears are most active at dawn and dusk when temperatures are cool. During berry season (August-September), bears sometimes feed all day — especially in bumper crop years when competition is low. Set up on glassing points overlooking known food sources — berry patches and oakbrush slopes — during the first and last 2 hours of daylight for the highest encounter rates.
How competitive is the draw for Unit 1 elk?

What rifle caliber should I use for Unit 1 elk?
Colorado mountain elk country can produce shots at any range from 50 to 500+ yards depending on terrain. A flat-shooting caliber in the .270, .30-06, 7mm Rem Mag, or .300 Win Mag range covers the range of shot opportunities. Practice at field-realistic distances (200-400 yards) before the hunt. A quality bolt-action rifle with a 3-9x or 4-14x scope is the standard tool for Colorado elk.

Check CPW's Draw Odds statistics for current point requirements and annual applicant data. Apply every year regardless of your point total to maximize your odds in the preference draw.
What is the best time to call moose in Unit 1?
Colorado moose are in their rut from mid-September through early October. The peak calling window is typically the first two weeks of October. Cow calls work at all times of day — a bull in rut may approach at any hour. Early morning is typically the most productive, with the first 2 hours after dawn offering the best conditions for locating and calling bulls in riparian habitat.
How competitive is the draw for Unit 1 mule deer?
Unit 1 mule deer draw competitiveness depends on the specific hunt code (weapon type, season, sex restriction). With approximately 23 applicants per year, check CPW's Draw Odds statistics for current point requirements by hunt code. Colorado's preference-point system rewards consistent annual applications — apply every year to accumulate points.
What gear is essential for hunting Unit 1 mule deer?
A quality optics system — 10x binoculars and a spotting scope — is the most critical gear investment for mule deer hunting. Colorado mule deer country demands long-range glassing before committing to a stalk. Add comfortable boots for terrain-specific conditions (mountain boots for steep country, lighter footwear for plains), a daypack, and a rangefinder for complete gear preparation.
How competitive is the draw for Unit 1 pronghorn?
Unit 1 pronghorn draw competitiveness depends on the specific hunt code (weapon type, season, sex restriction).

Shooting sticks, a bipod, or a pack-braced position from prone are recommended for field-realistic practice. A flat-shooting rifle in .243, .25-06, 6.5 Creedmoor, .270, or similar caliber handles any Colorado pronghorn shooting scenario.
