Unit 446

East Big Belt

Rolling foothills and moderate forest between the Smith River and Gates of the Mountains Wilderness.

Hunter's Brief

Unit 446 spans rolling terrain with pockets of timbered country and open ridges between White Sulphur Springs and the Smith River drainage. The landscape transitions from lower sage and grassland valleys into forested slopes and scattered peaks. Fair road access via county and forest service roads provides reasonable entry points, though the terrain grows rougher at higher elevations. Limited water sources require advance planning. Elk, mule deer, and whitetails inhabit the forested drainages; lions follow the same corridors. Pressure concentrates near accessible trailheads, leaving rougher country less crowded.

Terrain Deep Dive

Landmarks & Navigation

The Dry Range anchors the unit's northern reaches, providing high vantage points for glassing and orientation. Elk Ridge and Camas Ridge offer ridgeline travel routes and observation zones. Mount Edith and Boulder Baldy serve as summit references visible from lower country.

The Smith River corridor forms a natural travel zone, while the Beartooth WMA boundary and its fence line near Hump Cabin mark a critical public/private boundary. Duck Creek Pass offers a recognized crossing between drainages. These features help hunters navigate a complex landscape where many roads dead-end at private gates.

Elevation & Habitat

The unit drops from nearly 9,500 feet on high ridges to around 4,000 feet in the lower drainages, creating distinct habitat zones. Lower elevations feature sage flats and grassland interrupted by cottonwood draws along streams. Mid-elevation slopes transition to mixed conifer and aspen, becoming progressively denser with ponderosa and Douglas-fir as elevation climbs.

Upper ridges thin out into sparser timber with rocky outcrops. This vertical relief concentrates wildlife movement along predictable migration corridors—elk winter low and migrate upslope as snow recedes, while deer use all elevations seasonally based on food and cover availability.

Access & Pressure

Over 333 miles of roads exist across the unit, but most are private or forest service spurs serving ranches and historical sites. County Road 360 (Fort Logan-Milligan Road) provides the main public corridor northwest toward the Smith River. USFS roads #138 and #4143 offer official entry points but typically access national forest beyond unit boundaries.

Hunting pressure concentrates near White Sulphur Springs approaches and recognized trailheads. However, the patchwork of private ownership creates frustrating access—many logical drainage heads terminate at gates. Early season sees more pressure; winter and late-season crowds thin dramatically.

Knowing which drainages have actual public access separates successful hunts from failed scouting missions.

Boundaries & Context

Unit 446 encompasses rugged country in central Montana, bounded by White Sulphur Springs to the south and the Gates of the Mountains Wilderness to the north. The Smith River forms the western boundary, while the Big Belt Mountains define the southern edge. Meagher and Lewis and Clark County lines bisect the unit.

Despite its vast acreage and significant terrain complexity, most land is private, limiting public hunting options. The unit's core sits between two major geographic anchors that make orientation straightforward, though finding accessible public land requires knowledge of specific boundaries and gate locations.

Water & Drainages

Water is the limiting factor here. The Smith River provides the primary reliable source but forms the unit's western boundary. Within the unit, perennial creeks include Porcupine, Onion, Indian, and Slough Creeks—all draining from higher elevations and concentrated in specific valleys.

Several named springs exist (Haystack, Ashford, Weston, Den Gulch, Crystal) but aren't guaranteed flow in late season. Multiple reservoirs and stock tanks dot the landscape (Doggett, Ayers, Keep Cool, Jackson, Hanson), though many dry or become unreliable by fall. Understanding drainage patterns and spring locations is essential—dry camps force long water hauls.

Hunting Strategy

Elk in this unit use the forested drainages and mid-elevation parks for summer range before dropping to sagebrush valleys and timber fringes at first snow. Early season requires finding bulls in scattered meadows and timber pockets; rut activity moves animals predictably along drainage systems. Mule deer inhabit the rolling ridges and aspen transition zones, vulnerable to early-season glassing from high vantage points.

Whitetails cluster in the densest timber and creek bottoms. Mountain lions follow all three species, especially deer concentrations in late season. The terrain complexity demands patience—this isn't wide-open country.

Hunt water sources in dry periods, use high ridges for glassing mornings and evenings, and focus on drainages where public access clearly exists before burning time on posted gates.
