Unit 31

Little Mountain

Semi-arid basin and ridge country overlooking Flaming Gorge Reservoir with scattered timber and seasonal water.

Hunter's Brief

Unit 31 is open country characterized by sagebrush basins interrupted by juniper-dotted ridges, anchored on its western edge by Flaming Gorge Reservoir. Elevations climb gradually from around 6,000 feet near the water to nearly 9,200 feet on the higher ridges. Access is limited to a network of county roads and rough terrain; Sage Creek Road and Ramsey Ranch Road provide primary entry corridors. Water is scattered through the unit—seasonal creeks and springs punctuate the drainages, but reliability varies. Elk use these basins seasonally, moving between low-elevation winter range and higher terrain as conditions shift.

Terrain Deep Dive

Landmarks & Navigation

Sheep Mountain and Ramsey Peak anchor the eastern terrain and serve as useful reference points for glassing or navigation. Flaming Gorge Reservoir dominates the western boundary—a major landmark visible from most of the unit and critical for orientation. Currant Creek and its forks cut through the central basins, creating the primary drainage system hunters follow.

Hogback Ridge and Big Ridge provide elevated vantage points for surveying the country. Several basins—Buster, Buckskin, and Wildhorse—define the terrain's character and offer moderate glassing potential. Sugarloaf Reservoir and The Narrows provide secondary orientation points; major springs like Big Spring and Washam Spring mark reliable water locations in otherwise dry country.

Elevation & Habitat

The unit spans a modest elevation range, with low sagebrush and grassland flats beginning around 6,000 feet and transitioning to scattered juniper and limber pine as terrain rises toward 9,200 feet. The habitat is primarily open semi-arid rangeland—big sagebrush, bitterbrush, and native grasses—with islands of conifer cover on north-facing slopes and ridge tops. Most terrain sits in the 6,500 to 8,000-foot band, making this classic Great Basin shrub-steppe country.

Water-loving riparian zones follow creek bottoms where aspen and willows crowd drainages. The sparse tree cover keeps sightlines long, typical of high-desert elk habitat where herds use open country for feeding and canyons for shelter.

Access & Pressure

Limited road density keeps human pressure relatively low and access challenging. Sage Creek Road and Ramsey Ranch Road serve as primary entry corridors, connecting to Highway 191 at the southern boundary. These are county routes—passable in normal conditions but rough in winter or after rain.

Most of the unit requires foot travel or ATV use beyond the main roads. Limited accessibility paradoxically creates opportunity; most casual hunters don't venture far from road ends. The terrain's modest complexity (6.1/10) means that hunters willing to walk can slip away from pressure quickly.

Staging areas exist around Highway 191 and Sage Creek access points, but the country rewards those patient enough to cover distance on foot.

Boundaries & Context

Unit 31 sits in southwestern Wyoming's high-desert country along the Utah border, anchored by Flaming Gorge Reservoir on the west. The unit spans roughly 30 miles east-west from the reservoir to Highway 191 and extends north from the Utah state line to Sage Creek. Gentle terrain dominates much of the western and central portions, while ridges and buttes break up the landscape to the east.

The boundaries follow natural features—Sage Creek and its tributary system, county roads, and Highway 191—making navigation straightforward, though the country itself remains remote and relatively undeveloped.

Water & Drainages

Water availability is a defining feature and potential constraint. Flaming Gorge Reservoir ensures reliable water along the western boundary, but away from it, options thin considerably. Currant Creek and its forks, along with Spring Creek and West Fork Trout Creek, represent the main drainage system; these flow seasonally or year-round depending on snowmelt and precipitation.

Scattered springs—Washam, Spitzi, Greasewood, Big Spring—dot the basins and ridges, particularly near higher terrain. Sugarloaf Reservoir provides another option in the eastern portion. During dry periods, water becomes the limiting factor; hunters must plan routes around known springs or accept pack-in water.

Early season and spring conditions generally offer better water distribution.

Hunting Strategy

Unit 31 historically holds elk in its basin and canyon systems. Early season hunting focuses on open sagebrush country where elk feed in cool morning hours before retreating to scattered timber or canyon breaks. The elevation band—primarily 6,500 to 8,000 feet—supports reliable September elk hunting.

Rut period hunting (September-October) can be productive in canyon systems like Lowe Canyon and along Currant Creek where bulls concentrate. Late season requires patience; elk retreat to thicker cover on north-facing slopes and use springs and creeks as anchors. Water sources become critical hunting markers—glass from ridge tops overlooking basins where animals must eventually drink.

The moderate elevation means early snow rarely shuts down hunting, but preparation for variable weather is essential. Boot travel and cow calling techniques often outperform more aggressive tactics in this open country.
