Unit 99

Meyers Ridge, Mumford Ridge, and Moslander Ridge are the primary ridgelines for orientation and glassing platforms. Table Mountain, Chapman Butte, and Bridger Butte are distinctive summits visible across the terrain for navigation. Numerous parks and meadows—Gourley Meadows, Cowboy Cabin Park, Deadhorse Park, Jacks Park—are natural concentration areas worth checking.

Van Tassel Lake and Meeks Cabin Reservoir are notable water features; smaller ponds like Archie Pond and Lake Louise provide secondary reference points. Chalk Creek Basin and Leavitt Basin are broad sagebrush valleys; Tipperary Bench, Leavitt Bench, and Bigelow Bench define the bench country. The Needles and Rocky Point are minor cliff features adding visual character.

The unit spans medium elevations from around 6,500 to just under 10,000 feet, with most country in the 7,000–8,500 foot band. This is sagebrush-dominated landscape with pine groves scattered across benches and ridge tops; timber is sparse overall. Habitat transitions from open flats and meadows in the basins to slightly more timbered benches as elevation rises.

Vegetation is typical high-desert—big sagebrush on the flats, scattered Douglas fir and lodgepole on higher ground, with occasional aspen in drainages. The landscape is broken and rolling rather than steep; benches and flat parks are defining features. Early season means open basins are productive; as seasons progress, animals may shift to slightly higher timber.

Fair access via Highway 414 and a network of 684 miles of roads makes the unit reachable but not overdeveloped. Small towns on the eastern flank—Lonetree, Altamont, Mountain View—provide camping and supply points. County roads connect the main drainages and benches, allowing reasonable vehicle access into mid-unit country.

Private ranches checker the area, so road routes and access points matter; public vs. private boundaries require attention. The terrain's size and moderate accessibility mean pressure is present but not crushing; hunters willing to glass open country and work away from main roads can find quieter ground. Early-season crowds tend to concentrate along main access corridors.

Unit 99 straddles the Wyoming-Utah border south of Interstate 80, bounded by Highway 414 on the east and the Hoop Lake-Hole-in-the-Rock Road on the south. The unit encompasses the rolling country around Lonetree, Altamont, and Mountain View—small communities that define its eastern access corridor. Fort Bridger sits outside the unit to the north but serves as a natural staging area.

The terrain is largely high-desert benchland with scattered groves and open basins; it's broad country without significant wilderness designation but with enough size to offer hunting room. The Wyoming-Utah state line forms the southern and western boundary.

Water is limited but present at key locations. Sulphur Creek, Van Tassel Creek, Mill Creek, and Spring Creek are the main year-round creeks; they're valuable for both drinking and potentially locating animals. Basin Creek, Bull Creek, Coyote Creek, and others run seasonally—useful early in the season but unreliable in fall.

Numerous springs dot the unit: Pitcher Spring, Rocky Springs, Bigelow Springs, Big Spring, and Cold Springs are named reliable sources. Several reservoirs exist—Byrne Reservoir, Sulphur Creek Reservoir, Meeks Cabin Reservoir—adding water security. In this semi-arid country, knowing spring and creek locations is tactically important; pronghorn congregate near reliable water, especially in late season.

Unit 99 is pronghorn country—the open benches and sagebrush flats are classic pronghorn habitat. Early season offers the best opportunity as herds are visible crossing open country; glass the parks, benches, and basin edges where pronghorn congregate. Water sources become critical magnets by mid-season; position yourself near creeks or reservoirs where animals must drink.

The sparse timber offers minimal cover; hunting is glassing-intensive with long stalks across open ground. Ridgeline glassing from Meyers Ridge, Mumford Ridge, and the benches pays dividends. Avoid heavy timber; focus on transition zones and open parks.

Early mornings on benches and evenings near water are prime times. The landscape's breadth means finding animals requires patience and binoculars, not bushwhacking.
