Hunt Area 155, Crystal Peak, Wyoming

Hunt Area 155 is a high-elevation mountain unit covering approximately 355 square miles (227,226 acres) in Teton and Sublette Counties. The unit is defined on the northwest by the Gros Ventre River and Highway 191, on the southwest by the divide between the Gros Ventre and Hoback Rivers near Hodges Peak, and extends through ridges including Pyramid Peak, Cache Peak, and Jackson Peak toward the National Elk Refuge boundary near Jackson. Elevations range from roughly 6,500 ft in valley drainages up to peaks exceeding 11,000 ft. Terrain is characterized by steep rocky slopes (80% of the area has slopes equal to or less than 24 degrees), high alpine basins with year-round snowfields and lakes, dark conifer timber (lodgepole pine, spruce-fir), aspen parks, and open sagebrush parks at lower elevations. Deep canyons channel travel from the alpine zone to lower winter range.

Approximately 99% public land: roughly 98% U.S. Forest Service (Bridger-Teton National Forest) and 1% Wyoming state land, with only about 1% private. This is one of Wyoming's most public-land-accessible deer units. Primary access routes include the Hoback Canyon corridor via US-191/189 to the south, the Gros Ventre Road northeast of Jackson, and numerous USFS two-track roads and trailheads off Hwy 191 through the Pinedale Ranger District. Non-resident hunters hunting designated wilderness areas within the unit are required to use a licensed Wyoming guide. Walk-In Areas (WIA) exist in both Teton and Sublette Counties adjacent to this unit for additional private-land access; consult the WGFD Walk-In Atlas for current enrollment.

High-elevation conifer forest (Engelmann spruce, subalpine fir, lodgepole pine) dominates mid-elevations with thick timber patches interspersed between rock slides. Alpine meadows with grasses, forbs, and wildflowers occupy high basins and provide summer deer forage. Aspen groves appear on mid-elevation aspects and are particularly attractive to elk. Lower drainages and valley floors transition to sagebrush-grassland parks. Year-round water is abundant from snowmelt streams, alpine lakes, and basin springs. The unit historically supported 25,600-38,400 mule deer at objective population levels; the Sublette herd, of which this unit is a part, sat at 22,437 post-season in 2025 and is trending upward.

Mule deer in this unit participate in long-distance seasonal migrations characteristic of the greater Sublette and Wyoming Range herds. Deer move to high alpine basins and ridges during summer (June-September), descend through conifer timber and aspen zones during the general rifle season (October), and push to lower sagebrush winter range in the Green River Basin and surrounding areas as snow accumulates. Elk herds are present in the unit and surrounding drainages; the greater Pinedale region manages nearly 10,000 elk across three large herds with liberal antlerless opportunity. White-tailed deer occupy riparian corridors (Gros Ventre River, Hoback River bottoms) in smaller numbers. Pronghorn are present at lower elevations in adjacent areas but the steep high-country of unit 155 is not primary pronghorn habitat. Breeding (rut) for mule deer typically begins in late October and can extend through late December.

Season dates reflect 2025 WGFD Chapter 6 regulations — archery statewide September 1-30 is well-established; general/rifle season dates for limited-quota areas in this region typically run approximately October 1 through mid-November but exact open/close dates for the specific Type 1 (any buck mule deer) license in area 155 should be confirmed against the official Chapter 6 document at wgfd.wyo.gov. Harvest statistics by individual hunt area are published in WGFD annual deer harvest reports but were not available at unit-level granularity from public web sources at time of research; Sublette herd-wide success rate of approximately 29% (2025 season) is used as the best available proxy. The 2024 season introduced a four-point-or-better antler restriction for mule deer in portions of the Sublette herd to support buck age-class recovery; verify whether this applies to area 155 specifically. Area 155 absorbed area 146 for the 2026 deer hunting season per WGFD boundary changes. This profile was assembled from WGFD news releases, regulation documents, HuntScore, and regional hunting press — all figures should be verified against current WGFD Chapter 6 and harvest reports before publication.
