Unit 36B

Steep mountain terrain in central Custer County with alpine basins and rugged ridgelines.

Hunter's Brief

High-elevation mountain country spanning from mid-elevation forests to alpine tundra across Custer County. Terrain is steep and complex with significant elevation relief, making physical demands substantial but rewarding for mountain goat hunters. Multiple drainages, ridges, and basins provide diverse terrain to work, though water sources are scattered and require planning. Access is available via connected road network, but much hunting happens on foot once you're in the mountains. This is terrain that rewards patience and conditioning.

Terrain Deep Dive

Landmarks & Navigation

White Mountain and Ramshorn Mountain anchor the higher terrain and provide excellent glassing reference points. Buffalo Ridge and the summits including Keystone Mountain, Corkscrew Mountain, and Twin Peaks form the backbone ridgeline system. For practical navigation, Spruce Gulch, Bull of the Woods Gulch, and Beardsley Gulch serve as key drainages that funnel toward hunting areas.

Slab Barn Lake and Twin Creek Lakes mark reliable high-elevation reference points. These landmarks work together to create a navigable system of ridges and valleys—hunters should focus glassing efforts on exposed terrain above timberline, using prominent summits and basin edges as orientation points.

Elevation & Habitat

The unit spans mid-elevation forestlands rising into alpine basins and ridgelines. Lower valleys and flats support mixed forest with open meadows—Spring Basin, Eddy Basin, and Willow Patch provide staging areas and lower-elevation transition zones. As elevation increases, terrain becomes increasingly steep and open, moving into alpine parkland and rocky ridgelines where mountain goats operate.

The forested middle elevations transition sharply to exposed rock, talus, and sparse vegetation at higher elevations. This vertical stacking creates distinct habitat zones that goats exploit seasonally, moving between protected forest draws and exposed alpine terrain.

Access & Pressure

Connected road network provides reasonable access to trailheads and approach points throughout the unit's lower elevations. Over 730 miles of roads create multiple staging options near Challis, Custer, and Bayhorse. However, actual hunting terrain requires serious foot travel once you're above roads.

The steep, mountainous topography means most access pressure concentrates on ridgelines and popular basins reachable from common trailheads. Terrain complexity rewards exploratory hunters willing to work the less-obvious drainages and ridges. Early-season and late-season hunting typically sees lighter pressure; mid-season concentrates effort on accessible high-country basins.

Boundaries & Context

Unit 36B occupies that portion of Custer County bounded by the surrounding terrain of central Idaho's high country. The unit encompasses steep mountain geography with substantial elevation variation—from mid-elevation valley floors near populated places like Challis and Custer to true alpine terrain above 10,000 feet. The terrain is predominantly mountainous with moderate forest coverage typical of Idaho's central ranges.

Towns like Bayhorse and Clayton provide local reference points for access. The connected road network threads through the unit's lower elevations, offering reasonable approach routes to foot-access terrain above.

Water & Drainages

Water sources are limited and scattered, requiring careful planning. Multiple springs—Snyder Springs, Third Spring, Stovepipe Spring, and Daugherty Spring—dot the unit but aren't guaranteed reliable. Polecamp Creek, Ramey Creek, Buckskin Creek, and Sixmile Creek provide perennial water in mid-elevation drainages.

Bayhorse Lake, Eddy Lake, and Twin Creek Lakes offer alpine water sources, though elevation and seasonal snow conditions determine access windows. Hunters should plan water strategy carefully, locating springs before committing to high-elevation camps. Late-season hunting may require identifying reliable seeps or snowmelt rather than depending on traditional water sources.

Hunting Strategy

Unit 36B is mountain goat terrain—steep, rocky, and demanding. Focus on exposed alpine ridges, rocky outcrops, and cliff faces where goats seek escape terrain. Glassing from distance is essential; scan skylines of major summits and ridge systems using prominent terrain features as reference points.

Early morning light favors spotting goats on exposed rock faces. Work from below upslope when possible, using terrain features to conceal your approach. Late season (after early winter snow) can concentrate goats in lower basins seeking forage, but elevation and terrain complexity remain the primary factors.

Physical conditioning and patience are non-negotiable—this terrain is unforgiving and goats are found where the country gets steepest.
