Unit 76

Copper Mountain

High desert basins and open ridges meet the Wind River Reservation boundary across sparse sagebrush country.

Hunter's Brief

Unit 76 spreads across expansive sagebrush and grassland terrain at moderate elevation, ranging from low desert valleys to scattered ridge country. The landscape is predominantly open with sparse timber, broken by numerous draws and basins that funnel game movement. Access requires patience—roads are limited and often rough, making this country feel more remote than its actual size suggests. Water is scarce and scattered, so reliable springs like Red Springs and Dye Springs become critical waypoints. This unit rewards hunters willing to glass country and cover ground methodically rather than those seeking easy access.

Terrain Deep Dive

Landmarks & Navigation

The Bridger Mountains form the primary reference point along the unit's northern edge, providing reliable visual anchors during navigation. Black Butte and Monument Hill stand as prominent summits useful for glassing and orientation across the open basins. Multiple named basins—Jack Welch, Minnick, Devils Punch Bowl, and Woods—create distinct geographic subdivisions that help organize hunting approaches.

The Murphy Dome-Mud Creek Road (B.L.M. 1409) and Nowater Stock Drive Road (B.L.M. 1404) serve as key access corridors, though both require capable vehicles. Blue Ridge and Lake Creek Divide offer elevated vantage points for surveying surrounding country.

Elevation & Habitat

Terrain slopes gradually upward from around 4,200 feet in the lower valleys to 8,200 feet on higher ridges, creating a bands of sagebrush and grassland country typical of Wyoming's transitional zones. Low desert basins dominate the western and southern portions, giving way to rolling sagebrush-covered slopes as elevation increases. Timber is sparse throughout—scattered juniper and ponderosa cling to select draws and north-facing slopes, but this is fundamentally open country where distances matter.

The medial elevation near 5,100 feet places most terrain in the classic antelope and mule deer belt, with scattered pockets suitable for pursuing larger game species.

Access & Pressure

The unit's sparse road network—142 miles of roads across vast terrain—creates genuine remoteness despite the 'Limited' accessibility badge. Most roads are B.L.M. tracks requiring high-clearance vehicles, particularly after storms. East Thermopolis and Nickelson Place exist as reference points rather than staging areas.

Because roads don't penetrate deeply and trailheads require knowledge of local terrain, human pressure concentrates along accessible creek drainages and basin edges. Interior basins and ridge country above the road network see minimal hunting pressure, rewarding those willing to hike away from parking areas.

Boundaries & Context

Unit 76 occupies the transition zone between the Wind River Reservation to the south and the drier sagebrush country spreading northward across Hot Springs County. The unit's western boundary traces the Bighorn River northward from Gold Creek, while eastern boundaries follow divides between major creeks—Nowater, Nowood, Badwater, and Buffalo—that drain the surrounding terrain. The northern and eastern sections fold along classic Wyoming drainage patterns, with creeks and washes creating natural travel corridors.

Murphy Dome and Copper Mountain anchor key ridgelines that separate basins and define the unit's backbone structure.

Water & Drainages

Water defines strategy in this unit. Permanent springs are widely spaced: Red Springs, Dye Springs, Winter Spring, Big Spring, and Black Sulphur Spring anchor different sections but often require significant travel between them. Kirby Creek Reservoir, Gardner Reservoir, and several other impoundments provide reliable water during certain seasons, though these are irrigation structures that fluctuate.

The Bighorn River forms the western boundary but lies outside practical hunting range for most of the unit. Seasonal draws and unnamed seeps supplement these sources, but hunters must plan water sources before heading into particular basins or ridges.

Hunting Strategy

Unit 76 is pronghorn country primarily, with habitat suited to antelope throughout the open basins and grassland slopes. The sparse sagebrush and wide-open sight lines create excellent opportunity for spot-and-stalk hunting, though thermal cover can be challenging in afternoon hours. Mule deer use the scattered timber pockets and steeper draws, particularly along creek bottoms and canyon systems.

The complexity of the unit—numerous basins, ridges, and divides—allows hunters to establish territory and work methodically. Early mornings and evenings, when antelope move between bedding and feeding areas in these open landscapes, present peak opportunity. Water availability directly controls animal distribution during dry periods, making spring locations tactical focus points.
