Unit 35
Henry's Fork
High desert basins and sparse ridges around Flaming Gorge, moose country with limited road access.
Hunter's Brief
Unit 35 is expansive high-desert terrain framing Flaming Gorge Reservoir, characterized by sagebrush flats interspersed with scattered timber and eroded ridgelines. The landscape spans from the Green River's corridor north to Interstate 80, with elevations ranging through lower montane country. Road access exists but is minimal and seasonally variable, requiring patience and preparation. Water is available through the reservoir, scattered creeks, and reliable springs. This is complex country that rewards route-finding skills and rewards solitude-seeking hunters willing to work for it.

Terrain Deep Dive
Landmarks & Navigation
The Flaming Gorge Reservoir dominates orientation and serves as the unit's focal point—a reliable reference visible from much of the high country. The Bald Range and summits like Haystack Buttes, Cedar Mountain, and Massacre Hill provide glassing vantage points and navigation references across the sagebrush expanses. Major drainages including Cottonwood Creek, Beaver Creek, and the Green River establish travel corridors and concentrate water.
The Bluffs offer distinctive topography for navigation. Named springs like Carter Spring, Whiskey Spring, and Big Spring serve as critical water sources in the arid basins. These features help break the vast terrain into understandable sections.
Elevation & Habitat
The terrain spans from moderate elevation river bottoms near 6,000 feet to higher ridges approaching 9,600 feet, creating distinct habitat zones. Lower elevations feature sagebrush-dominated flats and basins—Devils Playground, Sage Creek Park, and Poverty Flats represent classic high-desert country. Mid-elevation slopes and benches support scattered conifer stands and aspen pockets, particularly around named features like Leavitt Bench and Cottonwood Bench.
Sparse forest coverage means open sight lines across much of the terrain, with timber concentrated on northfacing slopes and creek bottoms. The country breaks into numerous draws, hollows, and benches that funnel water and wildlife movement.
Access & Pressure
Road density is minimal, with roughly 600 miles of road scattered across vast terrain—creating pockets of accessibility surrounded by significant stretches of country requiring foot travel. USFS roads and ranch roads provide limited vehicle access, heavily dependent on seasonal conditions and private land permissions. Most access clusters around reservoir margins and major drainage corridors.
The limited road network actually favors patient hunters willing to hike; most pressure concentrates near pullouts and lower elevation entries. Higher basins and remote ridgelines see minimal traffic. Seasonality and weather significantly impact road conditions, requiring careful planning and flexibility.
This is country where boots matter more than wheels.
Boundaries & Context
Unit 35 occupies the country surrounding Flaming Gorge Reservoir and the Green River drainage, with Interstate 80 forming its northern boundary and the Wyoming-Utah state line marking the southern limit. The Stateline Dam Road (USFS 072) and Wyoming Highway 410 define western boundaries. This is genuinely vast terrain—the reservoir itself dominates the landscape, creating a central water feature and geographic anchor.
Rendezvous and Mountain View represent the nearest population centers on the periphery. The unit encompasses historic valleys and hollows named by early mountain men and settlers, though today it remains remote and lightly populated.
Water & Drainages
Flaming Gorge Reservoir provides reliable water across much of the unit, but hunters working the higher basins and ridges depend on scattered springs and seasonal creeks. Cottonwood Creek, Beaver Creek, North Creek, South Creek, and Big Dry Creek drain the interior, with flows varying seasonally. Multiple named springs including Carter Spring, Whiskey Spring, Box Spring, and Big Spring provide water in otherwise arid country—critical for understanding moose habitat and movement.
The Green River's main channel runs along the unit's northwestern edge. Water scarcity in the high basins means successful hunting requires locating and understanding these reliable sources, which concentrate both game and hunting pressure.
Hunting Strategy
Unit 35 holds moose in classic high-desert habitat—scattered timber around the reservoir margins, creek bottoms, and the sagebrush-aspen transition zones typical of the region. Moose concentration follows reliable water sources: Flaming Gorge itself, major drainages like Cottonwood Creek and Beaver Creek, and scattered springs in the interior basins. The terrain's sparse forest means glassing is productive from ridgelines and benches, though moose often feed in willow-choked drainages inaccessible to vehicles.
Early season opportunities target bulls working the timber and aspen; mid to late season shifts moose into drainage bottoms and creek basins as higher country snow accumulates. Successful hunting requires locating water in the high basins, then working slowly along creek and spring locations where moose feed. The complexity of navigation and minimal road access reward thorough preparation and patient glassing.
