Unit 240
2
Steep Bitterroot alpine terrain with glaciated peaks, basin meadows, and challenging mountain goat country.
Hunter's Brief
Unit 240 spans the high Bitterroot Mountains between Lolo and Lost Trail Pass, offering steep alpine and subalpine terrain with significant elevation gain. Access is available from Lolo Pass Highway 12 and US 93 corridors, with a network of roads and trails providing entry points to drainages. Water is scarce at higher elevations but scattered lakes and streams in lower valleys support travel and staging. Expect rugged, remote terrain requiring good fitness and navigation skills to reach productive goat country.

Terrain Deep Dive
Landmarks & Navigation
The Bitterroot Mountains crest itself is the dominant feature, with named summits including Heavenly Twins, Ward Mountain, Como Peaks, Totem Peak, and El Capitan providing natural navigation references and glassing perches. Poverty Slide, Castle Crag, and Ohio Side represent significant cliff systems where goats find escape terrain. Key drainages for access include Capitan Creek, Twelvemile Creek, and the various forks of Bear Creek and Lost Horse Creek—these drainage systems provide natural travel corridors from lower roads up into alpine basins.
Little Grizzly Lake, Twin Lakes, and Lookout Lake offer water reference points and potential camps in the mid-elevations.
Elevation & Habitat
The unit spans from mid-elevation valley floors around 3,150 feet to alpine summits exceeding 9,900 feet, with most productive terrain concentrated above 6,500 feet. The landscape transitions from Douglas-fir and ponderosa forests in lower drainages through dense subalpine fir and spruce forests, then opens into alpine meadows, talus, and rocky ridges at elevation. Moderate forest cover reflects this transition—timbered slopes give way to increasingly open country as elevation climbs.
The steep topography means significant vertical relief in many drainages, creating distinct habitat bands within short horizontal distances. High basins like One Horn offer alpine meadows and benches where goats congregate.
Access & Pressure
The unit has nearly 1,200 miles of road in the surrounding valleys and lower terrain, indicating a well-connected network at lower elevations. However, the terrain complexity score of 7.4 reflects that accessing alpine goat country requires significant foot travel from these roads—steep slopes and high elevations mean road proximity doesn't translate to easy access. Most access comes from US 93 corridor around Lolo and US 12 at Lolo Pass, with trailheads and jeep roads providing entry to major drainages.
The combination of connected roads and steep, remote alpine terrain means accessible staging areas but relatively few people actually penetrate into high goat terrain. The wilderness character of upper basins provides natural pressure relief.
Boundaries & Context
Unit 240 encompasses the high country of southwestern Missoula and Ravalli Counties, bounded by the Montana-Idaho border on the west and south, with US Highway 93 and US Highway 12 forming access corridors along the eastern edge. The unit stretches roughly from Lolo in the north to Lost Trail Pass in the south, capturing the core of the Bitterroot Mountains crest and western drainages. This is substantial alpine terrain with significant relief and complex ridge systems.
The boundary captures both the main crest country and the western slopes draining toward Idaho, making it a large, geographically coherent piece of high mountain terrain.
Water & Drainages
Water sources are limited, particularly in the highest alpine terrain where much of the goat habitat exists. The unit contains numerous small lakes scattered through subalpine meadows and basins—Twin Lakes, Lookout Lake, Twelvemile Lake, Lost Horse Lake, and Kerlee Lake provide reliable sources where present. Named streams including Capitan Creek, Twelvemile Creek, Saint Mary Creek, and various fork systems offer water in lower and mid-elevation drainages.
However, above timberline water is sparse, requiring goat hunters to either access high basins near lakes or accept carrying water. Spring timing affects creek reliability—early season and post-rain periods generally offer better water availability.
Hunting Strategy
Unit 240 is mountain goat country—the steep terrain, cliff systems, and high alpine habitat define the hunting approach. Success depends on accessing high basins and ridgelines where goats use alpine meadows and cliff escape terrain. Focus on drainages like Capitan Creek, Twelvemile Creek, and the Lost Horse Creek system as entry routes, glassing from ridges and benches for goats in open basins and on cliff faces.
The limited water requires planning—identify reliable lakes or springs in your target basin before committing to a hunt. Early season offers longer daylight and potentially better goat visibility; later season can push animals into higher terrain. Expect to cover significant vertical elevation and navigate steep, loose terrain.
Physical conditioning and scrambling ability are prerequisites.
