Unit 41

Sierra Madres

High-elevation sagebrush and sparse timber spanning the Sierra Madre with moose habitat in remote drainages.

Hunter's Brief

Unit 41 covers high country between I-80 and the Colorado border, anchored by the Sierra Madre range. Elevations span from mid-6000s to near 11,000 feet across open sagebrush basins and timbered ridges with minimal water development. Road access is limited and scattered; most routes require high-clearance vehicles or boots. The terrain is complex and sprawling—expect serious navigation challenges and solitude. Moose inhabit the higher drainages and willow-lined creeks, making water sources and riparian habitat the key to finding them.

Terrain Deep Dive

Landmarks & Navigation

The Sierra Madre range anchors navigation, with Green Mountain, Sheep Mountain, and Quartzite Peak serving as major reference points for orientation. Atlantic Rim, Deep Creek Rim, and Cottonwood Rim provide visual landmarks visible across the basins. Miller Hill Lake, Eightmile Lake, and Hog Park Reservoir mark reliable water features.

Key passes—Bridger Pass, Battle Pass, and Blue Gap—funnel travel routes through the terrain. Basins like Sage Creek, Wild Horse, and Eversole provide open country for glassing. These features are spaced far enough apart that route-finding requires solid map work and land navigation skills.

Elevation & Habitat

The unit spans nearly 4,800 vertical feet, rising from around 6,250 feet in the lower basins to just under 11,000 feet on the highest ridges. Most terrain sits in the 7,000-to-9,000-foot band—high enough for cool summers and long snow seasons, low enough for sagebrush rather than alpine tundra. Lower elevations host sagebrush flats and scattered juniper; mid-elevations transition to ponderosa and Douglas-fir slopes; upper ridges support spruce and fir with openings that form natural parks and meadows.

The sparse timber badge reflects the dominance of open sagebrush basins over dense forest, though significant timber corridors follow the major drainages.

Access & Pressure

Road density is low and most routes are rough. Over 1,180 miles of road exists, but consists mainly of rough BLM and county two-tracks requiring high-clearance vehicles or offering limited access to trailheads. No interstate highways or major paved roads cut through the unit.

This isolation keeps most recreational traffic out and hunting pressure relatively low. However, access limitations also mean hunters must plan carefully—you can't simply drive to a remote drainage. The trade-off is clear: solitude requires commitment and vehicle capability.

Small towns on the periphery (Encampment, Baggs) are the logical staging points.

Boundaries & Context

Unit 41 sits in south-central Wyoming, bounded by I-80 on the north, Wyoming Highway 230 on the east, the Wyoming-Colorado state line on the south, and Wyoming Highway 789 on the west. The Sierra Madre dominates the western portion, while lower basins spread eastward toward the North Platte River drainage. The unit encompasses vast sagebrush country interspersed with forested ridges and deep canyon systems.

The towns of Encampment, Savery, and Baggs lie just outside the western and southern boundaries, serving as the primary access points. This is genuinely remote country—the unit's isolation is part of its character.

Water & Drainages

Water is sparse but concentrated in drainages. Cottonwood Creek, Savery Creek, and Coal Bank Creek represent the most reliable permanent flows. Numerous springs dot the unit—Chicken Spring, Pop Springs, Ninemile Spring—but their reliability varies seasonally.

The multiple reservoirs (Hog Park, Rollman, Rawlins) concentrate water in specific locations. Upper drainages and willow-lined creeks at higher elevations hold moose habitat. Lower basins are genuinely dry; hunters targeting moose must key on the upper creek systems and the limited lakes.

Water scarcity makes identifying reliable sources critical for trip planning.

Hunting Strategy

Unit 41 is moose country. Target the major drainages—Cottonwood Creek, Savery Creek, Coal Bank Creek—and the willow parks at higher elevations where moose browse. Early season hunting focuses on higher drainages as moose concentrate in cool, productive creeks.

Rut season (fall) concentrates bulls in lower basins and accessible drainage bottoms. Late season requires deeper penetration into terrain as snow pushes moose from high ridges. Glass from rim country and high benches early; as season progresses, concentrate on drainage hunting.

The sparse timber and open basins make glassing viable from distance. Elk and deer likely inhabit the unit but moose is the primary draw. Success requires conditioning, route-finding skill, and willingness to hike steep drainages for hours.
