Overview
Hunt Area 103 wraps the Raymond Mountain country west of Cokeville, bounded by the Bear River and the Wyoming-Idaho line on the west and the Salt River divide on the north and east. It is a small, steep, high-quality unit built around the Raymond Mountain Wilderness Study Area and the Sublette Range of the Bridger-Teton National Forest. The rugged canyons and aspen-conifer ridges hold elk, mule deer, moose, black bear and mountain lion, and the non-motorized core rewards hunters willing to walk or ride.
Terrain
Steep, dissected overthrust-belt ridges and canyons rising from the Bear River valley to Raymond Mountain, with a large roadless wilderness study area at its heart.
Cover: Aspen groves, Douglas-fir and lodgepole timber, mountain shrub and sage on lower slopes, with willow and grass in canyon bottoms like Groo Canyon.
Landmarks: Raymond Mountain · Raymond Mountain Wilderness Study Area · Groo Canyon · Bear River · Smiths Fork
Access
The core is Bridger-Teton NF and the BLM Raymond Mountain WSA — largely continuous public ground, but the WSA and Public Access Area are non-motorized (foot and horse only). The Raymond Mountain PAA road crosses private land, so stay on the designated route; the Bear River valley bottom near Cokeville is private ranch.
Managers: USFS Bridger-Teton NF (Kemmerer RD), BLM, private ranch, WY state trust
Access points: Raymond Mountain Public Access Area, 8.2 mi north of Cokeville on US 89/30 · Groo Canyon trailhead (foot/horse) · USFS Kemmerer Ranger District roads on the east side
Species notes
Rocky Mountain Elk
common qualityElk use the timbered Raymond Mountain benches and canyon heads, holding in the roadless core where hunting pressure is light.
- →Hike or ride into the WSA beyond the motorized closure to reach undisturbed elk
- →Glass aspen/timber edges and canyon heads morning and evening
- →Still-hunt Groo Canyon and adjacent draws
- →Let pressure from road hunters push elk toward your backcountry position
Mule Deer
common qualitySteep aspen and mountain-shrub slopes hold mule deer, with good bucks possible in the rugged, lightly hunted terrain.
- →Glass sage-and-aspen transition on the mid slopes at first light
- →Work the heads of the canyons where bucks bed in cover
- →Cover elevation on foot to find undisturbed deer
Moose
limited qualityShiras moose frequent the willow bottoms of Smiths Fork and the Bear River drainage in low, limited-quota numbers.
- →Still-hunt willow creek bottoms at dawn and dusk
- →Check riparian pockets and beaver ponds
- →Glass slowly through thick cover
Black Bear
limited opportunityBlack bears use the aspen and berry-rich mountain shrub of the Raymond Mountain high country.
- →Glass open aspen and shrub slopes in spring and early fall
- →Focus on berry patches and green forage draws
- →Hunt canyon edges at the timber-shrub interface
Pro tips
- →This is a walk-in/horse unit — plan for the non-motorized WSA core and hunt away from roads.
- →Use the Raymond Mountain PAA as your staging point and stay on the designated access route across private land.
- →Horses dramatically extend your reach into the roadless country.
- →Let other hunters' pressure from the road system move game into the backcountry to you.
- →Watch the weather — the unplowed access can strand you if a storm rolls in.
Watch out for
- !Non-motorized Wilderness Study Area and Public Access Area — no vehicles or ATVs in the core
- !Private ranch land in the Bear River valley and along the PAA access road
- !Unplowed, drift-prone access road in late season
- !Steep, rugged terrain with real physical demands and limited cell coverage
Logistics
Cokeville, just southeast of the unit, has basic fuel and supplies; Kemmerer and Montpelier, Idaho, offer fuller services. The Raymond Mountain PAA provides parking, horse corrals, a restroom and non-potable water but is not plowed in winter. Plan for a backcountry, non-motorized hunt and pack in what you need.
