Unit 320

Key landmarks for navigation and glassing include the Tobacco Root Range itself as the primary spine, with Potosi Peak, Cloudrest Peak, and Skihi Peak as major reference summits. The Jefferson-Ruby Divide and Madison-Ruby Divide form the primary ridgelines and define major drainages. Named basins including Bone Basin and Shaw Basin provide focal areas for goat concentration.

Windy Pass and Tom Graham Pass offer high crossing points and vantage areas. Upper Boulder Lake, Cliff Lake, and Crystal Lake mark reliable water locations in upper basins. Strawberry Ridge provides additional terrain structure and navigation reference.

These features create recognizable terrain corridors for hunting strategy.

Elevations span from lower valley floors near 4,250 feet to alpine peaks exceeding 10,500 feet, with most productive goat terrain concentrated above 8,000 feet. Lower elevations feature forested slopes and valley bottoms near streams; mid-elevation terrain transitions through mixed timber and open parks typical of the Tobacco Root environment. Upper elevations break into the alpine zone with sparse vegetation, exposed rock, and cliff systems where goats thrive.

The moderate forest coverage indicates intermixed timbered and open country throughout, providing goat escape terrain while keeping some basins accessible. Terrain complexity scores high (7.9/10), reflecting the steep, interconnected ridge systems and significant vertical gain.

The unit maintains connected road access totaling nearly 1,140 miles, primarily following valleys and lower-elevation routes rather than high-country penetration. Montana Highway 287 and connecting routes to I-90 provide the main valley corridors; staging areas cluster around Virginia City, Ruby, and Pony. The road network suggests moderate pressure potential with access concentrated at valley entries, while high alpine basins remain challenging to reach and likely see lighter foot traffic.

Goat hunting inherently limits pressure since only serious mountain hunters attempt this terrain. Strategic hunters can access trailheads from valley towns and push deep into the divide system where fewer competitors venture.

Unit 320 encompasses portions of Madison, Jefferson, and Silver Bow Counties centered on the Tobacco Root Mountains and surrounding ridges. The unit boundary follows Montana Highway 287 from Virginia City northwest toward Route 41, then through I-90 and down the South Boulder River drainage, before following the Jefferson-Ruby Divide back to the starting point. Nearby access towns include Virginia City, Ruby, Pony, and Norris.

The unit encompasses substantial elevation range across a complex ridge system with multiple distinct drainages and basins. This is true mountain country—big, interconnected ridgelines forming the Madison-Ruby and Jefferson-Ruby divides.

Water availability is limited overall, making reliable sources crucial for goat hunting strategy. Upper Boulder Lake, Cliff Lake, and Crystal Lake represent significant water features in high basins where goats concentrate. Mid-elevation drainages include Coal Creek, Little Cherry Creek, and the Noble Fork as navigation corridors with seasonal flow.

The South Boulder River defines the eastern boundary and provides perennial water at lower elevations. Multiple springs including Potosi Hot Springs, Bone Basin Spring, and Splan Springs offer scattered water access at various elevations. Limited water resources mean goats will concentrate around reliable alpine and subalpine sources, making these basins primary hunting focus areas.

Unit 320 is goat country, period. Focus on high alpine basins above timberline where goats feed on sparse vegetation and use cliff systems for escape. Glassing from high vantage points like peaks overlooking Bone Basin, Shaw Basin, and other named basins provides early-season strategy; plan for extended observation from 8,000+ feet elevation.

Water sources become critical—glass around Upper Boulder Lake, Cliff Lake, and Crystal Lake where goats congregate, especially during dry periods. The steep, complex ridge system requires excellent physical conditioning and rock scrambling ability; plan conservatively for daily distance. Expect to spend 8-10 days covering terrain thoroughly.

Early season (August-September) offers best weather for alpine travel; later seasons become increasingly risky with snow and exposure on high ridges. Goats concentrate in broken, cliffy terrain—avoid smooth slopes and focus glassing on areas where goats can escape to vertical rock.
