Unit 36B
High mountain terrain in the Salmon River range with steep drainages and alpine basins.
Hunter's Brief
Unit 36B is a remote, mountainous section of Custer County dominated by steep slopes and high-elevation terrain. The landscape transitions between forested ridges and open alpine basins, with elevations spanning from mid-elevation valleys to peaks above 10,000 feet. Access is primarily via existing trail and road network with limited trailheads. Water exists as scattered lakes, springs, and reliable creek systems, though some areas require strategic planning. The challenging topography and moderate accessibility mean hunters willing to climb will find less pressure than lower-elevation country.

Terrain Deep Dive
Landmarks & Navigation
Major summits including Keystone Mountain, Ramshorn Mountain, and White Mountain serve as primary navigation anchors and glassing platforms. Buffalo Ridge and the ridge systems running through the unit provide excellent high-ground vantage points. Twin Creek Lakes, Eddy Lake, and Bayhorse Lake offer recognized water sources and natural gathering points for travel planning.
Spruce Gulch and the interconnected gulch system provide logical drainage corridors for north-south movement. Stovepipe Spring and Fourth Spring offer additional water security for high-country camps. These landmarks create a natural hunting framework—climb to ridges for spotting, work drainages and basins for access.
Elevation & Habitat
Terrain climbs dramatically from mid-elevation valleys near 4,600 feet into high mountain slopes and basins exceeding 10,000 feet. The majority of the unit sits in the 7,000-9,500 foot band where ponderosa and Douglas fir transition to subalpine fir and whitebark pine. Open alpine meadows dot the highest elevations, interspersed with rocky outcrops and talus fields.
Lower valley floors support denser forest cover and grass parks. The moderate forest density suggests a mix of timbered slopes and open country—enough timber for cover but sufficient meadows and basins for glassing and travel. Seasonal snowmelt feeds persistent water through mid-summer, then becomes less reliable at higher elevations.
Access & Pressure
Connected road access totaling 857 miles suggests a trail and secondary road network rather than major highways—hunters aren't driving to trailheads on paved roads. The steep terrain complexity (7.5/10) inherently limits casual pressure; reaching quality country requires effort. Bayhorse and Clayton serve as staging points, but the remote high basins see limited daily traffic once above trailhead.
The combination of distance, elevation gain, and moderately challenging terrain creates natural solitude above 8,000 feet. Early season when snow lingers and late season when weather deteriorates see fewer hunters—timing matters here.
Boundaries & Context
Unit 36B encompasses the mountainous terrain within Custer County, anchored by the Salmon River Mountains as its geographic spine. The unit spans from populated places like Challis and Clayton on the periphery to remote high country at its core. Bayhorse serves as a historic reference point on the unit's western flank.
The landscape is fundamentally alpine and subalpine, characterized by major ridge systems and extensive valley networks carved by persistent drainages. This is genuine mountain country—steep, complex, and distance-intensive for hunters accustomed to more accessible terrain.
Water & Drainages
Water exists but requires local knowledge—not all basins run year-round. Marshall Creek, Pat Hughes Creek, and Sawmill Creek form the primary drainage system supporting reliable flow through mid-season. West Fork Creek and Sheep Creek provide secondary options.
The scattered alpine lakes including Twin Creek Lakes, Slab Barn Lake, and Spruce Gulch Lake offer reliable summer water for high camps. Lower-elevation springs like Snyder Springs and Daugherty Spring support early and late season hunting. The limited water badge reflects the alpine reality: plan water access before committing to high basins, particularly late in the season.
Hunting Strategy
Unit 36B is mule deer country across its elevation spectrum. Early season (late August-September) finds deer in alpine basins and high meadows before cooler weather pushes them downslope. Rut hunting typically occurs mid-to-late September when bucks move aggressively through transition zones between basins and timbered slopes.
Late season (October-November) concentrates deer in lower valleys and forested drainages where snow hasn't persisted. Glass high basins early and mid-season from ridge vantage points like Buffalo Ridge and the major summits. Work drainages like Spruce Gulch and the gulch system as thermal corridors during transition periods.
Water sources become critical—camp near lakes or springs to intercept deer movement. Success requires packing in; the terrain doesn't reward quick day hunts.
