Unit 80
Sheep Creek
Alpine cirque basin ringed by steep timbered peaks above the National Elk Refuge.
Hunter's Brief
Unit 80 is high-country terrain centered around forested ridges and alpine benches that rise sharply from the Gros Ventre and Flat Creek drainages. Elevations climb from mid-8000s into the 11,000-foot range, creating distinct autumn migration patterns. Access is limited to foot traffic and horse—roughly 87 miles of trail connect the main drainages, but the steep terrain and dense timber demand good navigation skills. This is compact country that concentrates hunting pressure in specific canyons and saddles.

Terrain Deep Dive
Landmarks & Navigation
Jackson Peak and Table Mountain anchor the eastern skyline and serve as key orienting features when glassing from distant ridges. Pyramid Peak marks the critical Cache Peak divide on the southern boundary—a major watershed separation that hunters use for navigation. Sheep Mountain provides another recognizable summit.
Goodwin Lake and Nowlin Creek offer reliable water sources in specific drainages. These features are spaced far enough apart that route-finding requires careful map work and trail discipline, especially in fog or early season conditions.
Elevation & Habitat
This unit is pure high country. The landscape transitions rapidly from mixed-conifer forest in the 8,000-foot basins to dense spruce-fir and whitebark pine near the 9,500-foot elevation gains, with open alpine tundra and windswept ridges dominating above 10,000 feet. Steep grades limit continuous forest coverage—instead, timber clusters in protected drainages and north-facing slopes while talus and alpine meadows open the upper terrain.
The transition zones between timber and open country create the primary elk habitat structure throughout the unit.
Access & Pressure
The 87 miles of trail network is deceptive—it's foot and horse traffic only, no motorized access. Trailheads are limited and scattered around the unit's perimeter, making true backcountry camping mandatory for effective hunting. The steep terrain and remote location deter casual hunters, but the proximity to Jackson and the National Elk Refuge means the accessible benches and lower drainages see regular traffic during rifle season.
Most pressure concentrates on main trail corridors and established camps; the higher ridges and side canyons see far fewer boots.
Boundaries & Context
Unit 80 forms a tight cirque basin east of Jackson nestled between major drainages—the Gros Ventre River to the north and Flat Creek to the south, with Granite Creek dividing the eastern flank. The Bridger-Teton National Forest boundary anchors the western edge while the National Elk Refuge abuts the north and northeast. This compact alpine zone sits immediately above some of the most heavily hunted country in Wyoming, making it a natural secondary option for hunters willing to climb above the crowds and access limitations of lower elevations.
Water & Drainages
Water exists but requires tactical planning. Nowlin Creek and the upper reaches of Flat Creek provide seasonal flow through the timber, while Goodwin Lake offers reliable water for basin hunting. Cache Creek drains the northwest sector.
Spring runoff guarantees flow in main drainages through mid-summer, but late-season hunts depend on cached water or careful timing near remaining springs. Thunderstorms are common in late August and September, temporarily improving water availability but creating navigation hazards in exposed terrain.
Hunting Strategy
This is elk country where high-country migration and ridge-running dominates the strategy. Early season finds elk in the alpine meadows and upper basins; as temperatures drop and snow moves in, migration southward and downslope accelerates. The steep terrain makes glassing essential—hunt saddles, ridge lines, and open parks where bulls buggle in the timber margins.
Fluid weather and rapid elevation changes demand alpine savvy. Success depends on understanding which drainages concentrate animals during different weather patterns and being willing to camp high and hunt before pressure pushes animals toward refuge boundaries.
