Unit 442

Bob Marshall Wilderness Complex

Steep timbered slopes and high basins spanning the Continental Divide above Sun River country.

Hunter's Brief

Unit 442 is mountainous country with dense forest coverage broken by parks and benches, ranging from mid-elevation valleys to high ridgelines along the Continental Divide. Access via connected road network reaches staging areas, though most hunting requires foot travel into steep terrain. The unit spans multiple drainages—Sun River, Teton River, and Beaver Creek systems—with limited water in some high basins but reliable creeks in major valleys. Elk and mule deer are the primary targets; expect moderate hunting pressure with solitude available in the steeper, timber-choked interior drainages.

Landmarks & Navigation

Key landmarks for orientation and glassing include Mount Lockhart and Chute Mountain as prominent high-country reference points; the ridgeline system of Wapiti Ridge and Black Reef offers vantage points across major drainages. Sawtooth Mountain anchors the southern boundary and is visible from many vantage points. The string of named parks—Round Park, Sawmill Flat, Tenmile Park—serve as natural travel corridors and hunting zones.

Elephant Head, Elk Hill, and Horse Hill provide secondary ridgeline features useful for navigation. Hidden Lake and Red Lake mark high-country locations; Diversion Lake and Gibson Reservoir provide lower-elevation reference points. These scattered landmarks help orient hunters in terrain that's otherwise dominated by timbered slopes and interconnected ridges.

Elevation & Habitat

Terrain spans from mid-elevation river valleys around 4,400 feet to high alpine ridges exceeding 9,300 feet, with the median elevation around 6,400 feet creating a mix of timbered slopes and open high country. Lower drainages support ponderosa and mixed conifer forest with open parks and meadows; mid-elevation slopes are heavily timbered with scattered clearings. Upper elevations transition to subalpine timber and sparse vegetation near ridge crests.

Dense forest dominates overall landcover, creating a landscape of dark timber interrupted by parks like Round Park, Sawmill Flat, Tenmile Park, and various gulches. This vertical relief creates natural habitat zones for elk migration between seasonal ranges.

Access & Pressure

The connected road network totaling over 450 miles provides access to the unit's perimeter and some interior staging areas; main access points include the Teton River Road to the east and Sun River Road to the west. Road density is moderate, meaning most hunters can reach parking areas but then face significant foot travel to reach productive country. Popular entry points experience typical season-opening pressure, but the unit's steep terrain and dense timber create natural filters—aggressive pressure dissipates rapidly beyond obvious trailheads.

The interior drainages, particularly the Lange Creek and Benchmark Creek systems, see considerably less foot traffic due to approach difficulty. Early-season access may be limited by snow on high passes; late-season routes through lower drainages remain viable longer. Solitude is achievable for hunters willing to work steep country.

Boundaries & Context

Unit 442 encompasses the high country between the Sun River and Teton River drainages in Lewis and Clark and Teton Counties, anchored by the Continental Divide running north-south through its core. The western boundary follows the Sun River Game Preserve border upstream from Diversion Dam to Sun River Pass; the eastern boundary runs down the Teton River drainage to the Forest Service line. The unit is moderately sized and mostly public land, positioned in the Bob Marshall Wilderness Complex region.

Geographic anchors include Sawtooth Mountain to the south, Fairview Mountain and Renshaw Mountain to the southwest, and the Continental Divide peaks to the east—establishing clear navigation references across varied terrain.

Water & Drainages

Water sources are limited at higher elevations but reliable in major drainages. The Sun River (North and South Forks) forms the western boundary and represents the primary drainage; Teton River system drains the eastern portion. Secondary creeks including Beaver Creek, Windfall Creek, Billie Creek, and Wright Creek provide water in mid-elevation drainages, though flows are typically summer-to-fall reliable.

High basins like Patricks Basin, Green Timber Basin, and Wagner Basin may hold water only seasonally. Medicine Springs and Scattering Springs offer known water sources but shouldn't be counted on for all-season hunting. Water strategy is important here—hunting camps should establish proximity to reliable creeks, and high-elevation hunts require planning around spring locations and seasonal water availability.

Hunting Strategy

Unit 442 holds elk, mule deer, white-tailed deer, and mountain lions across its elevation spectrum. Elk migration through the unit follows seasonal patterns tied to snow and feed—low drainages and parks draw elk in early season, mid-elevation benches and timber offer good September hunting, and upper elevations concentrate animals in late summer before snow pushes them down. Mule deer favor the broken, timbered terrain and parks at mid-elevations; white-tailed deer are concentrated in lower drainages and timber bottoms.

Mountain lion hunting follows elk and deer concentrations. Plan early-season hunts around the high parks and basins (Patricks Basin, Green Timber Basin) and mid-elevation benches; transition to lower drainages as weather deteriorates. The steep terrain requires fitness and glassing discipline—ridge systems and high benches offer vantage points to locate elk, while timber drainages demand methodical still-hunting.

Water-source hunting during warm weather can be productive, particularly in limited-water drainages where elk concentrate.
