Colorado GMU 61 Mule Deer Hunting
Mesa, Montrose, Ouray and San Miguel counties, southwest Colorado · 922 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 61 is like
GMU 61 spans 922 square miles across Mesa, Montrose, Ouray and San Miguel counties in the southwest region, encompassing rolling terrain with some steeper breaks. The unit ranges from 4,600 feet at its low end to 10,000 feet at the high end, with typical elevation near 7,400 feet. Most of the terrain is gentle or moderate — 58% gentle and 27% moderate by area — though steeper country comprises 13% of the unit and rugged ground 1%. This elevation range and slope mix support both summer and winter mule deer use across the season.
Public land dominates GMU 61, with National Forest and BLM ground comprising approximately 85% of the unit or roughly 780 square miles. National Forest accounts for about 49% of the unit and BLM for about 36%, both managed for multiple use and generally open to public hunting. Private land covers the remaining 15%. Access depends on specific roads, trailheads and entry points on public ground; hunters should verify current conditions on the ground before planning a hunt.
Mule deer occupy the unit across multiple seasonal ranges. Summer Range covers 90% of the unit, supporting bucks and does through the warmer months. As fall advances, deer shift toward winter ground; Winter Range encompasses 57% of the unit, and a Winter Concentration layer marks 18% as areas where mule deer cluster, indicating significant concentration on a defined portion of winter range. Migration Corridors cover 31% of the unit, identifying movement routes deer use as they transition between seasonal ranges. The timing and extent of this seasonal shift vary with weather and snow.
GMU 61 offers seven mule deer seasons, six of which are open to public applicants. Archery runs September 2–30 during the velvet shed period. Muzzleloader season follows September 12–20, also in the velvet shed phase. Four rifle seasons follow: 1st Rifle October 14–18 and 2nd Rifle October 24–November 1 both fall in the early fall migration phase, when bucks are becoming more active; 3rd Rifle November 7–15 spans the transition into the primary rut; and 4th Rifle November 18–22 coincides with the primary rut itself. A private-land-only season runs October 14–18. Hunter pressure is low across the unit. The draw for this unit is hard, with the easiest qualifying unit-wide buck or either-sex code for an adult Colorado resident requiring 3 to 5 preference points. Other weapons, seasons and nonresident applicants can require substantially more.

GMU 61 mule deer hunting FAQ
Can a hunter with zero preference points draw this unit?
No. The easiest unit-wide buck or either-sex hunt code for an adult Colorado resident requires 3 to 5 preference points. Nonresidents and applicants seeking premium buck seasons will face substantially higher point thresholds.
Where should a hunter focus during the early rifle seasons?
Early rifle seasons (October 14–18 and October 24–November 1) coincide with the early fall migration phase, when bucks are becoming more active and begin moving between summer and winter ranges. Deer will be transitioning, and migration corridors covering 31% of the unit mark key movement routes. As temperatures drop and November approaches, hunters can expect bucks to become more nocturnal and continue shifting toward winter ground.
What happens to mule deer distribution late in the season?
As the season progresses into November, mule deer shift from summer range toward winter ground. Winter Range covers 57% of the unit, and a Winter Concentration layer marks 18% where deer cluster, indicating significant concentration as the primary rut approaches and winter conditions intensify. The 4th Rifle season (November 18–22) coincides with the primary rut, when bucks are most active during daylight.
Is most of this unit actually huntable public ground?
About 85% of GMU 61 is National Forest or BLM land generally open to public hunting, roughly 780 square miles. Private land comprises the remaining 15%. However, access still depends on specific roads, trailheads and entry points on public ground; the ownership percentage does not guarantee easy or universal access.
How does terrain affect hunting difficulty across the unit?
The unit is predominantly gentle (58%) to moderate (27%) terrain, making it accessible for most hunters on foot. Steeper country (13%) and rugged ground (1%) are present but limited, so terrain itself is not the primary limiting factor in hunting the unit. Elevation ranges from 4,600 to 10,000 feet, with typical elevation near 7,400 feet.
Which rifle season falls during the rut?
The 4th Rifle season (November 18–22) takes place during the primary rut, when bucks are most active during daylight hours. The 3rd Rifle season (November 7–15) begins in the early pre-rut phase and overlaps into the primary rut, offering a window into rut behavior as it develops. Earlier rifle seasons in October fall in the early fall migration phase, before rut activity peaks.

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.
