Unit 149

The Teton Range dominates the eastern skyline; notable summits include Mount Meek, Green Mountain, and Treasure Mountain serve as key reference points for navigation and glassing. Dead Horse Pass, Hurricane Pass, and Mount Meek Pass offer ridgeline routes between basins. Major basins—Ricks, Hidden Corral, Alaska, Taylor, and Granite—provide natural gathering areas for deer and logical focal points for hunting strategy.

Grassy Lake Reservoir sits as a landmark at higher elevation. These features offer glassing vantage points and natural funnels worth investigating for sign.

Terrain spans from around 6,000 feet in lower valleys to over 11,000 feet on ridge summits and alpine basins. Lower elevations feature rolling forested slopes with mixed conifer—Douglas fir and lodgepole pine dominating the dense timber. Middle elevation bands transition through subalpine forest with increasing openings and meadows.

Upper basins and ridges break into alpine terrain with grass, shrub, and exposed rock. The elevation gradient creates distinct seasonal movement corridors for deer. Meadows—Coal Creek, Gibson, Indian, Willow, and others—provide critical early-season forage in openings surrounded by heavy timber.

Fair accessibility via 409 miles of road provides multiple entry points and staging options near Alta and along Highway 22. However, road density is light relative to the unit size, meaning most productive terrain requires foot access. This creates a natural tiering: lower roads attract typical pressure, but the dense timber and rolling terrain absorb hunters quickly once away from corridors. The high complexity score (7.3/10) reflects how easy it is to get turned around in the timbered country; terrain that looks simple on maps often proves more difficult in reality.

Unit 149 occupies the western slopes of the Teton Range and surrounding foothills, bounded by the Wyoming-Idaho state line on the west, Yellowstone's southern boundary to the north, and the Caribou-Targhee National Forest edge on the east. Wyoming Highway 22 forms the southern boundary, accessible near the small community of Alta. The unit sits in a transition zone between Idaho's Basin and Range country and the higher peaks of the Teton-Yellowstone ecosystem.

Most terrain is public land, creating substantial hunting opportunity despite moderate overall size.

Despite the 'Limited' water rating, alpine lakes scatter throughout the unit—Hidden Lake, Junco Lake, South Leigh Lakes, and others provide reliable water at higher elevations. Lower drainages including Hominy Creek, Game Creek, Jackass Creek, and Grassy Creek offer seasonal flow. The challenge is accessing reliable water in the mid-elevation timbered zones where most hunting occurs during shoulder seasons.

Winegar Hole and scattered meadows provide early-season water, but late-season hunts may require planning around identified springs—Crystal Spring, Badger Spring, Nelson Spring—or carrying water into higher camps.

Mule deer and whitetails both inhabit this unit across elevation zones. Early season finds deer using lower meadows and timber edges—scout Coal Creek, Gibson, Indian, and Willow Flats. Mid-elevation timber holds summer range; post-opening pressure pushes animals into denser cover and higher basins.

Rut activity likely concentrates in mid-elevation saddles and basins where does congregate—Dead Horse Pass, Phillips Pass, and transitions between forested slopes offer movement corridors. Late season forces concentration on remaining forage and reliable water sources in lower valleys. The dense timber demands glassing meadows at distance rather than pushing through brush; use ridge systems and high vantage points to locate deer before committing to stalk.
