Unit 24

Big Piney

High-elevation Wyoming Range terrain with rolling ridges, alpine basins, and challenging access through timbered country.

Hunter's Brief

Unit 24 sits in the upper reaches of the Wyoming Range, a high, rolling landscape of forested ridges and open alpine basins split by multiple drainage systems. Access is limited to roughly 500 miles of rough roads threading through the Bridger-Teton National Forest boundary and surrounding terrain—most hunting happens from foot traffic once you reach staging areas. Water is scattered but present in named creeks and lakes throughout the unit; the terrain complexity is moderate-to-high, with significant elevation and ridgeline navigation required. This is sheep country with substantial vertical and terrain demands.

Terrain Deep Dive

Landmarks & Navigation

The Wyoming Range itself provides the dominant geographic anchor, with named summits including Mount McDougal, Mount Darby, and Coal Mine Mountain offering glassing vantage points. Riley Ridge, Deadline Ridge, and Witherspoon Ridge form key navigation features running north-south through the unit. Thompson Pass and Cheese Pass provide strategic passage through high terrain.

Roaring Fork Lakes and the Piney Lake system (Middle, North, and Soda Lake) mark reliable water zones for orientation. Lewis Falls and Menace Falls highlight major drainage features. The Red Castles area stands out as a distinctive landmark in the southern portion.

Elevation & Habitat

Unit 24 spans high-elevation terrain from roughly 6,500 feet to over 11,300 feet, with the bulk of country falling between 8,000 and 9,500 feet. Lower elevations feature scattered timber and open meadows—Foster Meadows, North Piney Meadows, and Coyote Park break up lodgepole and whitebark pine forest. Mid-elevations transition to more open ridge systems and timbered benches where sheep habitat becomes primary.

Alpine basins and rolling ridgelines above 9,500 feet offer the most open terrain for bighorn use and hunting. Vegetation shifts from dense forest in drainages to sparse, windswept alpine tundra on high divides.

Access & Pressure

Nearly 500 miles of roads provide access, but density metrics indicate a sparse network concentrated on forest service routes and lower-elevation approaches. Main access points likely cluster around LaBarge Creek, the Greys River drainage, and Hoback River approaches. Road quality varies from maintained FSR to rough two-track; high-clearance or 4WD becomes necessary for reaching upper trailheads.

Most hunting pressure concentrates on accessible lower drainages and meadow areas near roads. Upper ridge systems and alpine basins receive lighter pressure due to hike-in requirements and route-finding complexity. Weather and snow severely limit fall season access windows.

Boundaries & Context

Unit 24 encompasses the central Wyoming Range and surrounding alpine terrain, bounded by major drainages and forest boundaries. LaBarge Creek forms the southern anchor, with the Greys River system defining the western boundary and Hoback River drainage marking the eastern edge. The unit sits entirely within or adjacent to Bridger-Teton National Forest, roughly 40 miles east of the Wyoming-Idaho border.

Snyder Basin and Foster Meadows anchor major valleys within the unit. The terrain is isolated from major highway corridors, requiring access through forest roads and limited gateway communities.

Water & Drainages

Water is limited but strategically distributed. Poison Creek, Crow Creek, Marten Creek, and Blind Bull Creek run through major drainages and serve as travel corridors and water sources. The Piney Lake system and Roaring Fork Lakes provide alpine water but are elevation-dependent.

Triplet Vents and Apple Green Geyser mark geothermal features. Spring availability varies by season—reliable sources exist in established creeks but alpine basins dry quickly. Hunters must plan water access carefully; late-season hunting demands knowing specific spring and lake locations, and relying on creeks in deep canyons limits high-elevation hunting flexibility.

Hunting Strategy

Unit 24 is bighorn sheep country in steep, alpine terrain requiring backcountry skills and optics. Sheep occupy high ridges, cliff systems, and alpine basins above timber. Early season offers accessibility as snow hasn't blocked high passes; rut activity concentrates rams along ridge systems where glassing from distance reveals groups.

Terrain complexity demands route-finding ability—sheep use escape terrain near cliffs (South Rim, Red Castles area) that hunters must approach carefully to avoid spooking. Spring and summer snowmelt establishes reliable water in creeks; by fall, alpine lakes become primary. Success requires understanding escape routes, using distant glassing, and planning water access.

Physical conditioning is mandatory for the elevation and sustained ridge walking.
