Unit 107

Hickey Mountain

High-desert basin country anchored by Flaming Gorge, sparse timber and sage with moderate water scattered throughout.

Hunter's Brief

Unit 107 spreads across the rolling high desert east of Flaming Gorge Reservoir between 6,000 and 9,600 feet. The country is predominantly open sagebrush and grassland with scattered pockets of timber at higher elevations. Access comes via Highway 414 and 410 through Mountain View, with rough forest roads reaching into the interior. Water exists in numerous small reservoirs, springs, and creeks, though scattered rather than abundant. Elk country with moderate complexity—the terrain is navigable but large enough to avoid early-season pressure if you explore beyond the main drainages.

Terrain Deep Dive

Landmarks & Navigation

Haystack Buttes and Beacon Light Hill provide visual reference points across the open terrain, useful for orientation when glassing from distance. The Bluffs command the landscape along major drainages and offer vantage points for surveying multiple basins simultaneously. Cedar Mountain, Hickey Mountain, and Black Mountain form small massifs that break the horizon and provide thermal cover for elk.

Leavitt Basin, Cedar Basin, and Cow Pit drainages cut through the sagebrush country and offer natural travel corridors. Firehole Canyon and its tributary system create defined valleys that funnel water and concentrate wildlife movement.

Elevation & Habitat

Terrain rises from the low-elevation basin floors near Flaming Gorge to scattered higher benches and small mountain masses throughout. The landscape is predominantly open sagebrush plains and grassland with sparse timber concentrated on north-facing slopes and higher ridges. Elevation zones transition from low desert sage at 6,000 feet through juniper and piñon woodlands in the mid-bands, with scattered ponderosa and Douglas-fir on the highest benches above 8,500 feet.

The sparse forest badge reflects this composition—most of the unit remains open country suitable for long-distance glassing and cross-country travel.

Access & Pressure

Highway 414 and 410 provide reasonable access through Mountain View, connecting to Forest Service roads that penetrate the interior basins. The 606-mile road network is substantial, but road density is limited—most serve old agricultural water systems and ranch infrastructure rather than recreation. This creates opportunities: early-season hunters often concentrate near roads, but the large unit and sparse timber mean quiet country exists away from obvious staging areas.

Private land near towns and along major drainages creates a patchwork, requiring attention to boundaries. The moderate complexity score suggests navigating across country or following ridgelines rewards preparation.

Boundaries & Context

Unit 107 occupies the high desert country between Flaming Gorge Reservoir on the west and the Green River on the east, running from the Wyoming-Utah border north to Interstate 80 near Mountain View. The unit's western boundary follows Stateline Dam Road and Highway 410, while the eastern edge traces the Green River before turning back south along the reservoir shoreline. This 606-mile road network suggests substantial development history—old ranch and mining access—but the vast terrain and sparse population distribution mean much interior country remains lightly traveled.

Mountain View and Lyman serve as primary staging towns.

Water & Drainages

Flaming Gorge Reservoir anchors the western portion, while the Green River controls the eastern boundary, providing reliable water year-round. Interior water sources include numerous small reservoirs (Soap Holes, Cottonwood, Cedar Mountain, Hickey Mountain, and others) scattered across basins and saddles—most reliable in spring and early summer. Major streams like Beaver Creek, Cottonwood Creek, and Leavitt Creek flow seasonally through major drainages but may be unreliable by late summer.

Scattered springs (Carter, Chicken, Whiskey, Big, Corral) provide supplemental water but require knowledge of their locations. Buckboard Wash and Little Dry Creek serve as secondary drainage routes.

Hunting Strategy

Elk occupy this unit seasonally, using higher-elevation timber in summer and moving to open sagebrush basins and lower drainages for fall hunting. Early season, focus on north-facing timber pockets and cooler benches above 8,000 feet where scattered Douglas-fir and ponderosa provide cover. During the rut, elk transition to open country and major drainages—Firehole Canyon, Beaver Creek system, and Cottonwood Creek attract concentrated herds.

The sparse timber limits thick cover for stalking; instead, use elevation changes and basin transitions to locate animals during early morning and evening. Late season, lower elevations near the reservoir and main drainages provide the best opportunity as snow pushes elk downslope. Water sources make logical stopping points for both scouting and hunting.
