Unit 96

Green Mountain

High-desert basins and ridges with scattered timber and limited water across the Sweetwater-Fremont transition.

Hunter's Brief

Unit 96 is big, open country split between sagebrush basins and sparse-timbered ridges in the 6,500-to-9,200-foot range. Most land is public, but the sparse road network means you'll cover ground on foot. Water is scarce and seasonal—reliable springs and small reservoirs are key anchor points. Access is limited; staging from Bairoil or Jeffrey City on the unit's periphery makes sense. Expect to glass extensively and hunt the terrain between scattered draws and ridges where mule deer concentrate around water and heavier timber patches.

Terrain Deep Dive

Landmarks & Navigation

Crooks Gap and Muddy Gap offer established passage points across major topographic breaks. Key summits include Crooks Mountain, Henry Peak, and Sheep Mountain—these serve as navigation anchors and glassing vantage points. Whiskey Ridge and Telephone Line Ridge form recognizable north-south terrain divides.

The Red Hills provide a distinctive eastern reference. Stratton Hollow, Sweeney Basin, and Osborne Draw are major basins worth remembering for water and deer movement patterns. These landmarks help orient yourself in country where roads are sparse and distances deceptive.

Elevation & Habitat

Terrain spans from mid-elevation sagebrush plains rising into higher ridgelines and scattered timber patches, with the highest points topping near 9,200 feet. Most country sits between 6,500 and 8,000 feet—classic high-desert basin-and-range terrain dominated by sagebrush, bunch grasses, and sparse juniper or ponderosa stands on ridges and north-facing slopes. The forest cover is minimal, concentrated on the higher slopes and sheltered draws.

This is open, exposed country where vegetation is low and water defines habitat value. Mule deer use the juniper parks and scattered timber for shelter, moving to basins and draws for grazing.

Access & Pressure

The sparse road network (235 miles total, mostly BLM and county roads) means vehicle access is genuinely limited despite the unit's vast size. Primary entries are the Bairoil Road from the southeast, Wamsutter-Crooks Gap Road from the north, and Hadsell Road from the west. Most roads are unimproved and weather-dependent.

This limited access translates to lower pressure, but also means significant foot travel required once you leave your vehicle. The remoteness is the unit's appeal—big country with few hunters, but you must be prepared to hike miles between water sources and productive terrain.

Boundaries & Context

Unit 96 sits in south-central Wyoming where Sweetwater and Fremont counties converge, bounded by U.S. 287 and Wyoming 73 on the east and north, with the Wamsutter-Crooks Gap Road forming much of the western spine. The unit encompasses roughly 235 miles of roads across vast, mostly trackless country between Jeffrey City (to the north), Bairoil (southeast), and the remote basins of the Osborne and Bison Basin areas to the west. This is genuine backcountry terrain—big, sprawling, and lightly pressured due to limited road access and rugged navigation.

Water & Drainages

Water is the limiting factor here. Major reliable features include Crooks Creek, West Arapahoe Creek, Warm Springs Creek, and Sheep Creek—these ribbons of water and the scattered reservoirs (Osborne, Hadsell, Speyers, Antelope, Cold Spring) concentrate game. Springs like Tierney, Hadsell, Brenton, and Happy Springs are crucial but may be seasonal or low-volume.

Small ponds (Woods Gulch, Boggy Springs) exist but shouldn't be relied upon alone. Successful hunting hinges on locating and scouting water sources before the season and understanding which are year-round versus early-season only.

Hunting Strategy

Mule deer inhabit this high-desert unit, using juniper patches and timber-lined draws for cover while feeding in sagebrush basins at lower elevations. Early season finds deer dispersed across higher ridges and timber; as pressure and heat increase, they concentrate near water in deeper draws and canyon systems. Mid-to-late season hunting focuses on Crooks Creek, Warm Springs Creek, and the major reservoirs where deer must drink.

Glass from ridgetops (Crooks Mountain, Henry Peak) to locate animals at first and last light, then stalk to water sources or timber edges. White-tailed deer are present but secondary—they favor the brushier creek bottoms and draws. Success requires patience, good optics, and willingness to cover significant ground on foot.
