Overview
Hunt Area 88, Greys Feedground, is a small (~18–21 sq mi) elk unit at the lower end of the Greys River drainage near Alpine in far western Wyoming, running from the Wyoming–Idaho line on the Snake River up the Greys River past Squaw Creek and the Stewart Sheep Trail. It is built around the WGFD Greys River feedground one mile south of Alpine, where more than 1,000 elk are wintered to keep them off neighboring private and out of town. The country is about 84% public — mostly Bridger-Teton National Forest — but the valley floor around the feedground is a mix of private ranch and seasonally restricted management land, and elk hunting here is closely managed to serve the feedground.
Terrain
The steep-walled lower Greys River canyon where it meets the Snake at Alpine, with west-facing timbered slopes climbing to ridges between the Salt River Range and the Wyoming Range.
Cover: Steep west-facing slopes of mixed aspen, conifer and shrubs with abundant natural springs, willow and cottonwood along the Greys and Snake river bottoms, and sage-grass benches.
Landmarks: Greys River · Snake River / Wyoming-Idaho line · Greys River feedground · Squaw Creek · Stewart Sheep Trail · Alpine
Access
Roughly 84% public — about 64% Bridger-Teton NF, 17% state and a few percent BLM — with 16% private concentrated in the valley bottom near Alpine and the feedground. This is contiguous forest country, NOT the southern-Wyoming checkerboard. The Greys River Road provides the main access up-canyon, but the feedground WHMA itself is closed to human presence December 1–May 1 and vehicles are restricted to marked roads; near-feedground elk hunting is tightly managed.
Managers: USFS Bridger-Teton NF, WY state trust, private ranch, BLM
Access points: WY 89 / US 26 at Alpine · Greys River Road (FR 10138) up the canyon · Squaw Creek and Stewart Creek roads · Bridger-Teton NF trailheads on the canyon slopes
Species notes
Rocky Mountain Elk
abundant opportunityThe whole reason the unit exists — over 1,000 elk winter at the Greys River feedground. Hunting is closely managed to keep elk off private and reduce depredation, so tags and opportunity are structured around herd control rather than trophy quality.
- →Hunt the steep, spring-fed timbered slopes above the canyon before elk move to the feedground
- →Glass west-facing aspen-conifer benches at dawn and dusk
- →Follow legal public ground up the Greys River away from the feedground closure
- →Time hunts to elk movement as early snow pushes animals toward winter range
Mule Deer
common opportunityMule deer use the canyon slopes and sage-mahogany benches; a modest population in the steep lower Greys country.
- →Glass south-facing mahogany and aspen benches at first and last light
- →Still-hunt the timber-sage edges on the canyon walls
Moose
limited qualityShiras moose hold in the willow and cottonwood bottoms along the Greys and Snake rivers and in spring-fed draws — low density but genuine trophy presence.
- →Glass river willows and beaver ponds morning and evening
- →Check spring seeps and riparian pockets on the lower slopes
Pro tips
- →Know the feedground WHMA rules cold — closed to human presence Dec 1–May 1, vehicles on marked roads only, gates kept closed for feedground livestock
- →This is a herd-management hunt, not a trophy unit — expect opportunity-focused elk hunting near winter range
- →Use the Greys River Road to reach legal public ground up-canyon and away from the closure and private bottoms
- →Time late hunts to the first hard snow that moves elk toward the feedground
- →The steep spring-fed slopes hold elk in cover — hunt slow and glass the aspen-conifer edges
Watch out for
- !Greys River feedground WHMA is closed to all human presence December 1–May 1
- !16% private ranch in the valley bottom near Alpine and the feedground — map boundaries carefully
- !Small unit tucked against town and private — respect depredation-sensitive management and neighbors
- !Steep west-facing slopes and canyon roads get icy and slide-prone after early snow
- !Grizzly and black bear occur in the drainage — bear-aware camping and meat care essential
Logistics
Alpine, at the mouth of the Greys River, has lodging, fuel, a grocery and dining, and the elk on the feedground are visible from the highway. Afton and the Star Valley to the south and Jackson to the northeast provide fuller services and the nearest hospitals. The Greys River Road is the spine of access up-canyon; carry recovery gear for muddy or snowy conditions.
