Mule Deer Hunting in Unit 91

Where to Find Mule Deer in GMU 91

Mule deer in GMU 91 use the canyon rims and draws of the lower Colorado Plateau terrain, transitioning between mesa-top sagebrush and pinyon-juniper canyon slopes seasonally.

Canyon Rims

Position yourself on BLM mesa rims above major drainages at dawn. Deer feed on mesa tops at first light and drop into the canyon shade as thermals develop. The Y-Creek and Douglas Creek drainages hold consistent deer populations.

North-Facing Slopes

Douglas fir and mountain mahogany on north-facing canyon walls provide deer cover during warm September conditions. Bucks bed in the timber shade and move to feed on sage and bitterbrush benches in the evening.

How to Hunt GMU 91 Mule Deer

The remote canyon terrain of GMU 91 rewards patient hunters who glass systematically before committing to stalks in the broken rimrock country.

Glass Before You Move

The canyon topography provides excellent glassing from rim edges. Spend the first hour of daylight glassing canyon walls and bench flats opposite your position. The semi-arid terrain means deer are visible at longer distances than in heavily timbered units.

Canyon Approach Stalks

Use canyon folds and wash systems to approach deer located on opposite walls. Wind swirls in canyon terrain — favor approaches from the canyon rim down rather than from the bottom up. Move deliberately and pause frequently in the broken rock.

Mule Deer Hunting in Unit 91

Unit 91 covers Colorado's eastern plains — shortgrass prairie and agricultural land and holds a resident mule deer population shaped by the terrain and vegetation of this part of Colorado. With approximately 27 applicants per year — a low-demand unit with realistic draw prospects, this limited-entry mule deer unit is managed by Colorado Parks and Wildlife to maintain quality buck-to-doe ratios and older age-class bucks where tag allocation allows.

Where to Find Mule Deer in Unit 91

Unit 91 mule deer occupy the plains-grassland landscape of eastern Colorado, using a combination of agricultural fields, sagebrush pastures, and riparian corridors.

Agricultural Fields and Dryland Wheat

Mule deer in plains units feed heavily on dryland wheat stubble, corn residue, and alfalfa during fall. Deer move from bedding cover in CRP grassland, draws, and cattail patches to ag fields at dawn and dusk. Glassing from elevated road shoulders can locate deer in open terrain.

Riparian Corridors and Draws

River and creek drainages provide the primary travel corridors and bedding cover in plains units. Cottonwood and willow riparian zones on public land — including SWA properties — hold deer through the season. Focus morning and evening hunts on these transition zones between open fields and cover.

CRP Ground and Sagebrush Pastures

Conservation Reserve Program (CRP) grassland and native sagebrush provide bedding cover and travel habitat. Check Colorado PLOTS and SWA maps for publicly accessible parcels within Unit 91 before your hunt.

How to Hunt Mule Deer in Unit 91

Hunting Unit 91 mule deer effectively requires understanding the seasonal patterns of Colorado deer and applying pressure-management tactics appropriate for the terrain.

Pre-Season Glassing

Invest time glassing Unit 91 in late August and early September when bucks are still in velvet and in summer patterns. Identify target bucks and memorize their terrain features. Velvet bucks are the most predictable — late August is the best time to find a specific animal before the season.

October Rut Hunting

Colorado's October rifle seasons are timed perfectly for the mule deer pre-rut and rut. Bucks abandon their tight summer ranges and cruise the terrain in search of does. Hunt all day during the peak rut — midday movement can be as good as dawn and dusk when bucks are actively covering ground.

Wind and Approach

Mule deer rely on their nose as much as their eyes. Hunt with the thermals — in mountain terrain, thermals rise as the day warms and fall at dawn and dusk. Plan your approach routes to keep wind in your favor at the time of day you're hunting each specific terrain feature.
