Unit 302

Sourdough Peak and Timber Butte serve as prominent navigation markers visible across much of the northern and central unit. The Tendoy Mountains define the eastern ridge system, valuable for high-elevation glassing. Morrison Lake, Poison Lakes, and Coyote Lake provide focal points for water-dependent hunting and navigation landmarks.

Major creeks—McNinch, Johnson, Thompson, Horse—run from ridgelines into drainages and serve as natural travel corridors. Muddy Hole Basin offers a recognizable low-elevation gathering area. These features break the high country into navigable sections without requiring constant map consultation.

The unit spans mid-elevation to high-elevation mountain terrain, with most country falling between 7,000 and 9,500 feet. Lower basin country in Muddy Hole and the drainages around Morrison and Rock Canyons sits around 5,500 feet with more open sagebrush and scattered timber. Mid-elevation slopes support mixed conifer and aspen patches—typical elk habitat.

Above 9,000 feet, terrain transitions to sparser forest with alpine parks and rocky ridges. The sparse forest badge reflects the basin-to-ridge pattern: open parks and sagebrush dominate the basins and south-facing slopes, while north aspects and higher elevations carry scattered Douglas fir and lodgepole.

Over 640 miles of rough roads thread through the unit, but these aren't maintained highways—many are old logging, ranch, or game roads requiring high-clearance vehicles or foot travel. The fair access badge reflects this reality: roads exist but don't provide easy entry everywhere. Cameron (via Highway 287) and Armstead area serve as logical staging points.

The rolling terrain and sparse road network create natural pressure zones around major creek bottoms and lower access points, with significantly less human impact in the upper basins and ridgelines. A willingness to walk beats a high-clearance vehicle in this country.

Unit 302 encompasses much of the high country between Highway 191 to the north and the Yellowstone Park boundary and Montana-Idaho border to the south, spanning Gallatin and Madison Counties. The eastern and western boundaries follow natural divides—the Madison-Gallatin River divide on the east, Route 87 and Highway 287 anchoring the northwest corner. This positions the unit as a significant block of remote mountain terrain, roughly 40 miles north-south and 20 miles east-west, sitting entirely above 5,500 feet elevation.

Multiple reliable creeks drain the unit: McNinch, Johnson, Thompson, Horse, and McBride creeks flow through major drainages. Several named springs—Porcupine, Burnt Fork, Rock Spring, and others—scatter throughout the basins and higher elevations. Morrison, Poison, and Coyote Lakes provide consistent water sources.

The moderate water badge reflects this distribution—enough sources to plan around, but not running water everywhere. Seasonal variation matters: spring runoff and late-season reliability differ significantly. Water access often determines elk location and becomes critical for late-season hunting or extended backcountry pushes.

Elk thrive in the mixed timber and park habitat across mid-elevations, with higher densities in the timber-aspen transition zones around 7,500-8,500 feet. Mule deer prefer open parks and ridge edges, concentrating in lower basins and south-facing slopes in early season, moving higher as summer heat intensifies. White-tailed deer occupy brushy canyon bottoms and riparian areas.

Mountain lions follow the elk and deer. Early season (September) finds elk in high basins near water; by rut, they migrate into timbered drainages. Late season pushes them lower—focus basins and creeks near 6,000-7,000 feet.

The rolling complexity and moderate water sources reward hunters who locate creeks first, glass basins from ridges, then stalk into timbered cover.
