Colorado GMU 461 Mule Deer Hunting
Jefferson and Park counties, central Colorado · 143 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 461 is like
GMU 461 spans 143 square miles across Jefferson and Park counties in the Central Region, encompassing rolling to moderately steep terrain with elevations ranging from 5,400 feet to 9,400 feet. The unit is 27% gentle, 51% moderate, and 22% steep by area, with a mean slope of 17.3 degrees. This topography suits hunters willing to cover moderate distance on foot, though the terrain does not present extreme obstacles to access.
Public land open to hunting comprises roughly 4.7 square miles (mostly National Forest and BLM ground) — approximately 3% of the unit. An additional 1.8% is Colorado State Trust Land where access depends on CPW's Public Access Program enrollment; only parcels enrolled in that program may be hunted. Roughly 21% of the unit is unclassified ownership, and private land accounts for approximately 72%. Legal access is the primary constraint here: even where terrain is walkable, hunters have limited ground they can dependably reach.
Mule deer occupy the unit across its full mapped range, with Summer Range covering 100% and Winter Range covering 97% of the total area. Winter Concentration grounds comprise 24% of the unit and mark areas where mule deer cluster during winter months. A Migration Corridor layer covers 2% of the unit, reflecting movement patterns. Seasonal range coverage supports expecting mule deer presence throughout the fall, with winter concentration areas becoming relevant as the season progresses toward the Primary Rut phase in mid-to-late November.
The unit offers six mule deer seasons, five of which are open to public applicants. Archery runs September 2–30 for either-sex hunting during the velvet shed phase. Muzzleloader season is September 12–20 for does and bucks. Three rifle seasons follow: 2nd Rifle October 24–November 1 (bucks only, spanning early fall migration and early pre-rut phases), 3rd Rifle November 7–15 (bucks only, spanning early pre-rut and primary rut phases), and 4th Rifle November 18–22 (bucks only, during the primary rut). A private-land-only season runs September 1–November 30. Early-season hunts occur when average highs are in the low 70s; by November, highs cool to around 50 degrees, with average snowfall reaching 4 inches. Draw difficulty for the easiest qualifying unit-wide buck or either-sex hunt code is easy, with applicants often drawing at zero preference points. Hunter pressure on the unit is extreme.

Cover classes from the USGS National Land Cover Database, split into elevation bands. “Other cover” is the remainder of the classification — bare ground, water, agriculture and developed land — and is left unnamed rather than guessed at.
Land & access
About 5% of GMU 461 is public land a hunter can count on — National Forest and BLM. A further 2% is State Trust Land, which is huntable only where CPW has enrolled it.
- National Forest5%
- BLM<1%
- State Trust Land2%
- Unclassified ownership21%
- Private72%
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 461 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 461 mule deer hunting FAQ
Can a hunter with no preference points draw this unit?
Yes. The easiest qualifying unit-wide buck or either-sex hunt code draws reliably at zero preference points in the primary draw. Applicants with no points can also enter the secondary draw (a separate June draw, random, open to anyone) or check the leftover list after the primary draw concludes — these are separate systems from the preference-point draw.
How much public land can a hunter actually hunt in this unit?
Roughly 4.7 square miles of National Forest and BLM ground are generally open to public hunting — about 3% of the unit. An additional 1.8% is State Trust Land, but access there depends on CPW's Public Access Program enrollment; only enrolled parcels may be hunted. Legal access is the limiting factor here, not terrain.
Is the terrain manageable for a hunter on foot?
The unit is 51% moderate and 27% gentle by area, making it walkable for most hunters, and the mean slope of 17.3 degrees is not extreme. However, the limited public acreage means walking ability matters less than legal access — hunters can move across walkable ground but may find few acres they can legally hunt.
Is this unit realistic to draw with limited preference points?
For the easiest unit-wide buck or either-sex hunt, yes — this code draws at zero points reliably. However, draw difficulty describes only the easiest qualifying hunt; other seasons, weapons, and nonresident applicants may require substantially more points. Anyone applying should check the specific hunt code before deciding.
When is the rut during the seasons offered here?
The mule deer rut occurs from mid-to-late November. The 3rd Rifle season (November 7–15) spans into early pre-rut and primary rut phases, and the 4th Rifle season (November 18–22) falls entirely within the primary rut. Archery and muzzleloader seasons occur earlier, during the velvet shed and early fall transition phases.
Does mule deer distribution shift during the fall season?
Seasonal range coverage is broad, but Winter Concentration grounds comprise 24% of the unit — areas where mule deer cluster. As the season progresses from early fall into late November, hunters should expect deer to concentrate increasingly on winter range, though timing and extent vary with weather and snow.

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.
