Overview

Hunt Area 107 (Hickey Mountain) fills the country between the Green River, Interstate 80 and the Flaming Gorge Reservoir down to the Wyoming–Utah state line. At roughly 70% public — mostly BLM — it is the most accessible of the far-southwest units, a mix of high desert, juniper breaks and the northern foothills of the Uinta Mountains. Elk are scattered with numbers building as snow pushes them off Utah, and the desert and breaks hold good pronghorn and mule deer.

Terrain

Open high desert and sage benches broken by juniper-clad canyons and rims dropping to the Green River and Flaming Gorge, rising to forested Uinta foothills in the south.

Cover: Sagebrush and desert shrub on the flats, pinyon-juniper on the breaks and rims, with aspen and conifer meadows on the higher southern slopes.

Landmarks: Flaming Gorge Reservoir · Green River · Hickey Mountain · Firehole Canyon · Wyoming–Utah state line

Access

The best public access in the far southwest — roughly 60% BLM, plus state and Forest ground — laced with a network of BLM roads and two-tracks. Checkerboard sections still appear near the I-80/Union Pacific corridor on the north edge; use GPS to stay legal. Flaming Gorge National Recreation Area boat and shoreline access opens otherwise-remote breaks.

Managers: BLM, USFS (Ashley NF / Flaming Gorge NRA), WY state trust, private ranch

Access points: I-80 exits west of Green River · Firehole Canyon Road to Flaming Gorge · WY-530 along the reservoir's west side · BLM two-track network across the breaks · Stateline / Hoop Lake roads on the south end

Species notes

Pronghorn

common quality

Wide public desert basins make this strong, accessible pronghorn country — the signature opportunity in the unit.

  • Spot-and-stalk the open sage using rims and draws for cover
  • Hunt water sources in dry early stretches
  • Cover ground on the BLM two-track network to locate bucks

Mule Deer

common opportunity

Mule deer use the juniper breaks and canyon rims along the Green River and reservoir, with bucks holding in the rougher country.

  • Glass juniper breaks and rims at first and last light
  • Still-hunt canyon pockets above the reservoir
  • Work higher southern slopes as snow arrives

Rocky Mountain Elk

limited opportunity

Scattered elk occupy the breaks and southern foothills, with numbers climbing as snow pushes animals north off the Utah high country.

  • Scout the timbered south end and drainages pre-season
  • Hunt later to catch the Utah snow push
  • Use ATVs to cover the extensive road network between glassing points

Pro tips

  • This is the far-southwest unit to pick for public access — mostly BLM with an extensive road network
  • Pronghorn on the open public desert are the standout opportunity
  • Glass the juniper breaks and rims above the Green River and reservoir for mule deer
  • Flaming Gorge boat and shoreline access reaches remote breaks
  • Still map the checkerboard near I-80 on the north edge with GPS

Watch out for

  • !Checkerboard sections near the I-80/Union Pacific corridor on the north boundary
  • !Private inholdings scattered among the public breaks
  • !Slick clay two-tracks after rain or snow — carry recovery gear
  • !Relentless wind on open flats and the reservoir
  • !Late-summer fire restrictions on BLM ground

Logistics

Green River and Rock Springs on I-80 provide full services, fuel and lodging to the north; McKinnon and Manila, Utah sit near the reservoir on the south end. Flaming Gorge NRA campgrounds offer a base close to the hunting.
