Unit 36A-2
High alpine terrain above timberline with steep cliffs, cirque basins, and limited water access.
Hunter's Brief
This is classic mountain goat country—steep, rocky alpine terrain centered around the Boulder Basin area of central Custer County. Elevations top out above 11,500 feet with significant cliff faces and escape terrain throughout. Access is via road to staging areas, then foot travel into alpine basins where goats frequent rocky ridges and talus slopes. Water is sparse in the high country; goats rely on snowmelt and occasional alpine lakes. Terrain complexity and elevation demand solid fitness and route-finding skills.

Terrain Deep Dive
Landmarks & Navigation
Boulder Peak and Easley Peak anchor the unit's high ridgeline and serve as primary glassing landmarks visible from distance. Crown Point offers cliff terrain characteristic of goat country. Boulder Lakes and Silver Lake provide water reference points and potential base camp locations in the transition zone.
Galena Peak and Silver Peak define the ridgeline system goats use for movement. The basin features—Boulder Basin, Quinnlin Gulch, and surrounding cirques—are where goats concentrate. These named features help break down navigation in complex terrain and provide visual anchors when glassing from high vantage points.
Elevation & Habitat
This is upper-elevation alpine and subalpine terrain. The median elevation near 8,600 feet reflects lower basin and staging areas; functional goat habitat begins above 9,500 feet and climbs to over 11,500 feet. Moderate forest coverage exists in transition zones below timberline—scattered subalpine fir and whitebark pine—but the core hunting terrain is above timberline with bare rock, talus fields, alpine tundra, and steep cliff systems.
Goats inhabit the vertical terrain: cliffs for escape, rocky ridges for travel, talus slopes for feeding and bedding.
Access & Pressure
Road access is well-connected to the Boulder staging area with 186 miles of road totaling unit-wide, providing reliable trailhead access. However, once foot travel begins, the steep alpine terrain naturally limits pressure. Most access pressure concentrates around Boulder Basin and established routes to high basins.
The steepness and elevation demand physical capability, which self-limits casual hunters. The connected road network means convenient access to the unit from town, but the vertical terrain and alpine complexity mean genuine solitude is attainable for hunters willing to move into the higher cirques and cliff systems.
Boundaries & Context
Unit 36A-2 occupies the high alpine core of Custer County's central mountains, bounded by the East Fork Salmon River drainage and anchored by Boulder Basin. The Boulder area serves as the primary access point and reference landmark. The unit is compact but genuinely alpine—peaks exceed 11,500 feet and the majority of huntable terrain sits above 9,500 feet.
Adjacent drainages including the South Fork and West Fork East Fork Salmon River provide geographic boundaries and drainage references for navigation and orientation.
Water & Drainages
Water is genuinely limited in the alpine zone. West Pass Creek, Silver Creek, and the larger East Fork Salmon River drainage system provide reliable flows in lower transition areas, but the actual goat terrain above 10,000 feet relies almost entirely on snowmelt seeps, occasional alpine lakes, and spring snowpack. Hunters must identify water sources before entering the high country or plan around early-season snow.
The main drainages—West Fork East Fork Salmon River and South Fork East Fork Salmon River—define the unit boundaries but are below core goat terrain. Alpine lakes like Boulder Lakes and Silver Lake and Governors Punchbowl are critical for camp logistics.
Hunting Strategy
Mountain goats are the singular focus. Goat habitat in 36A-2 is defined by steepness and cliff terrain: hunt high, glass from distance, identify goats on cliffs and ridges, then plan route access. Early season offers snow patches and concentrated water sources.
Goats migrate vertically through the season—watch for descent into subalpine basins as weather deteriorates. Key strategy involves glassing the cirques and cliff faces surrounding Boulder Basin, Easley Peak, and Boulder Peak zones from high vantage points, then executing long approaches up talus and scree. Route-finding and scrambling ability are essential.
Water scarcity means goats concentrate near reliable sources; identify these first. Success requires patience, optics, and solid alpine navigation.
