Unit 94

Twin Creek

High desert basins and sagebrush flats rimmed by sparse ridges and rolling foothills.

Hunter's Brief

Unit 94 is sprawling, high-elevation country defined by open basins, sagebrush flats, and scattered ridges between Lander and South Pass. The terrain averages around 7,000 feet with minimal forest cover—mostly dry, open country broken by creek drainages and occasional springs. Road access is limited to dirt tracks and rough two-tracks, making this a self-sufficient hunt. Water sources are scattered and seasonal. Expect to find mule deer in the basins and ridge systems; whitetails likely use riparian draws and lower creek bottoms. The vast acreage and sparse road network mean quiet country, but also mean water management and navigation planning are critical.

Terrain Deep Dive

Landmarks & Navigation

Crows Nest Basin anchors the northwestern section and offers orientation points for the open country. The Antelope Hills and ridgelines—Peabody Ridge, Blue Ridge, Horse Track Ridge—provide navigation waypoints and glassing platforms across the flats. Weiser Pass marks a natural crossing point through the ridge system.

The Sweetwater River corridor to the south is reliable for orientation and potential water, while the scattered historic towns (South Pass City, Atlantic City) serve as external references. Stough Lake and Lewiston Lakes provide water markers in the basin country. Springs (Diamond Springs, Saint Marys Spring, Sulphur Springs complex) are critical markers for water strategy.

Elevation & Habitat

This is high-elevation, semi-arid country averaging around 7,100 feet, ranging from 5,400 feet in lower basins to 8,700 feet on ridge tops. Vegetation is sparse—predominantly sagebrush and grassland flats with scattered juniper and pinyon woodland on north-facing slopes and ridgetops. Tree cover is minimal overall; what forest exists clusters in drainages and higher elevations.

The open terrain means big glassing country interspersed with creek-bottom riparian zones where cottonwoods and willows concentrate. This is genuinely dry landscape; understand water availability is your primary constraint.

Access & Pressure

Road density is minimal—roughly 266 miles of road total across vast acreage creates significant stretches of roadless country. Most access is via rough dirt tracks and two-tracks from Highway 28 and 287 corridors or from the mining town roads. The Bison Basin Road and Three Forks–Atlantic City Road are primary entry points, but even these are rough.

Limited road access means lower hunter pressure in the interior basins, but also means self-sufficiency is mandatory—reliable vehicle, fuel, water, navigation. Early season and pressure periods will see hunters concentrated near road-accessible basins; the big country between them remains quiet. Plan for long walks from road to productive country.

Boundaries & Context

Unit 94 occupies the country between Lander and South Pass, bounded by Highway 287 on the north and east, Highway 28 on the west, and the Sweetwater River corridor to the south. The Bison Basin Road and Three Forks–Atlantic City Road form eastern boundaries, enclosing a substantial chunk of the Wind River Range foothills and the high desert basins beyond. Historic mining towns—South Pass City, Atlantic City, Miners Delight—sit on or near the unit perimeter, marking the transition from active ranching country to backcountry terrain.

The unit's size and remote positioning make it a genuine backcountry experience without extreme alpine exposure.

Water & Drainages

Water is the limiting factor here. The Sweetwater River anchors the southern boundary and provides reliable flow, but reaching it requires significant effort from the basin interiors. Scattered springs dot the unit—Saint Marys Spring, Diamond Springs, Sulphur Bar Spring, Wagon Tire Spring among them—but their reliability varies seasonally.

Creeks like Little Antelope Creek, Slate Creek, and the Sulphur Creek forks flow through drainages but are seasonal or intermittent. Several reservoirs (Sandstone, Sevenmile, Silver Creek, Rock Draw, Jackson, Carr, Antelope Springs) exist but their accessibility and water level depend on season and private access. Plan water sources before entering the basin country.

Hunting Strategy

Mule deer thrive in this semi-arid basin-and-ridge ecosystem, using open sagebrush country for feeding and ridges for vantage. Hunt early season by glassing basins at dawn; bucks will be in sagebrush and scattered timber transitions. Whitetails inhabit riparian drainages and creek-bottom cover, particularly the Sulphur Creek system and lower creek drainages where cottonwoods provide shelter.

Water sources concentrate game in fall, making springs and creek crossings tactical locations as the season progresses. The sparse forest and open basins mean optics and glassing are primary tools. Navigate by ridge systems and creek drainages.

Expect to cover significant ground; the country is vast and deer can be far apart. Late season pushes game toward lower elevations and water; plan accordingly.
