Colorado GMU 441 Mule Deer Hunting
Moffat and Routt counties, northwest Colorado · 194 sq mi
Based on the EASIEST unit-wide buck or either-sex hunt code available to adult Colorado residents in the 2026 primary draw — the lowest preference-point tier that drew reliably. Private-land-only and Ranching for Wildlife hunts are excluded because neither is a unit-wide public-land opportunity — NOT because the public cannot draw them. A private-land-only license requires the hunter's own permission to hunt private ground; a Ranching for Wildlife license is valid on the participating ranches enrolled in that program. They are separate systems. Other weapons, seasons and nonresident applicants can require substantially more points. The band is a floor, not a target: even the easiest qualifying hunt here sits in that range.
What hunting GMU 441 is like
GMU 441 spans 194 square miles across Moffat and Routt counties in northwest Colorado, rising from 6,200 feet to 10,900 feet with a typical elevation around 7,200 feet. The terrain is rolling, with some steeper breaks: 57% of the unit is gentle, 39% moderate, and 3% steep, making most of the country walkable for hunters on foot. The unit is relatively large and offers access across a range of elevations and aspects.
Land ownership is dominated by private ground. Of the unit's 194 square miles, approximately 20 percent (38 square miles) is generally open to public hunting on National Forest and BLM land. An additional 10 percent (20 square miles) is Colorado State Trust Land, which is huntable only where CPW has enrolled it in the Public Access Program; a hunter should check with CPW to learn which parcels are open in any given year. Approximately 1.6 percent is unclassified ownership, and the remaining 68 percent is private. Legal access to public ground, rather than terrain difficulty, is the limiting factor for hunters here.
Mule deer occupy the unit across all elevations through the fall. Summer Range covers 100 percent of the unit, and Overall Range also covers 100 percent. Migration Corridors span 72 percent, reflecting significant movement through the unit as the season advances. Winter Range covers 36 percent, with Winter Concentration on 17 percent of the unit where mule deer cluster; the shift from summer to winter ground is expected as November progresses, though the timing and extent depend on weather and snow. Hunters should expect concentrated numbers of deer on winter concentration ground as conditions cool.
The unit offers seven seasons, five of which are open to the public. Archery runs September 2 to September 30 (either-sex), during the velvet shed and early fall transition phase. Muzzleloader runs September 12 to September 20 (doe or buck), also in the velvet shed phase. Three rifle seasons follow: the 2nd Rifle from October 24 to November 1 (doe or buck), falling in the early fall migration and early pre-rut phases; the 3rd Rifle from November 7 to November 15 (doe or buck), spanning early pre-rut and primary rut; and the 4th Rifle from November 18 to November 22 (buck only), during the primary rut. September temperatures average highs near 72°F and lows near 40°F with negligible snow. October highs drop to near 58°F with lows near 30°F and 1.7 inches of average snowfall. November sees highs near 43°F and lows near 20°F, with 9.6 inches of average snowfall, reflecting the seasonal cooling trend. Draw difficulty for the easiest qualifying unit-wide hunt is Moderate, requiring 1–2 preference points for an adult Colorado resident, though other seasons and nonresident applicants require substantially more. Hunter pressure on the unit is Extreme.

Land & access
About 20% of GMU 441 is public land a hunter can count on — National Forest and BLM. A further 10% is State Trust Land, which is huntable only where CPW has enrolled it.
- National Forest19%
- BLM1%
- State Wildlife Area<1%
- State Trust Land10%
- Unclassified ownership2%
- Private68%
Colorado State Trust Land is open to public hunting only where it is enrolled in CPW's Public Access Program. Check current enrollment before planning around it.
“Ownership unclassified” means the source dataset does not record an owner for that acreage. It is not known to be public or private.
Where mule deer live in the unit
Colorado Parks & Wildlife maps mule deer seasonal ranges statewide. This is how much of GMU 441 each range covers — the single best clue to whether mule deer are here in September, in November, or only passing through. The layers overlap, so they do not add to 100%.

GMU 441 mule deer hunting FAQ
How much public ground can a hunter actually walk on this unit?
Approximately 20 percent of GMU 441 is generally open to public hunting on National Forest and BLM land. An additional 10 percent is State Trust Land, but only parcels enrolled in CPW's Public Access Program are huntable; a hunter should contact CPW to confirm which State Trust parcels are open in a given year. Despite the unit's gentle and moderate terrain, legal access rather than terrain difficulty is the main constraint on how much ground is available.
Is this unit realistic for someone with no preference points?
An adult Colorado resident with zero preference points can draw the easiest qualifying unit-wide buck or either-sex hunt code. The 2nd and 3rd Rifle seasons (doe or buck) both require 1–2 points and sit in that Moderate draw-difficulty band. The 4th Rifle (buck only) and some other seasons require substantially more points, so applicants should check the current preference-point structure for their intended hunt code.
When is the rut on this unit, and which seasons overlap it?
The primary rut on this unit occurs November 11 to November 25. The 3rd Rifle season (November 7–15) overlaps the early pre-rut and the start of the primary rut. The 4th Rifle season (November 18–22) falls entirely within the primary rut. The archery and muzzleloader seasons in September occur during velvet shed, not the rut, so bucks are not yet in rut behavior.
Should a hunter expect deer to be in different places in October versus November?
Yes. Summer Range covers the entire unit early in the season, but Winter Range covers only 36 percent. Migration Corridors span 72 percent of the unit, reflecting significant movement as the season advances. By November, as temperatures drop and snow accumulates (averaging 9.6 inches), deer are expected to shift toward winter ground; however, the timing and extent of that movement varies with weather and snow, so conditions late in the fall can differ from the average.
What kind of terrain should a hunter expect to cover in this unit?
Fifty-seven percent of the unit is gentle terrain, and 39 percent is moderate slope, making most of the country readily walkable for hunters on foot. Only 3 percent is steep. However, the real constraint is legal access: only about 20 percent of the unit is open to public hunting, so terrain ease does not translate to unlimited roaming room.
Why is draw difficulty labeled 'Moderate' if hunter pressure is 'Extreme'?
Draw difficulty and hunter pressure measure different things. Draw difficulty reflects how many preference points are required to draw the easiest qualifying unit-wide hunt; Moderate (1–2 points) means the tags are not highly competitive. Extreme hunter pressure means many hunters are on the ground once the season starts, crowding the available public land. A unit can draw easily but still be very crowded once hunters are there.

Draw difficulty is a qualitative band, not published odds — the note under the summary above states exactly which hunt code it describes. Land shares are separate, non-overlapping categories: publicly owned is not the same as open to hunting, and State Trust Land is huntable only where CPW has enrolled it.
