Unit 341

The Boulder River-Slough Creek Divide and the Hellroaring Creek-Mill Creek system form major ridge systems useful for navigation and understanding drainage flow. Mt. Cowen and Elephant Head Mountain anchor the eastern ridgeline and serve as visual reference points.

Sugarloaf Mountain and Beals Hill offer glassing vantage points for spotting activity in adjacent parks and valleys. The numerous gulches—Sunday, Powder, Sheep, Slab, and others—drain toward main creeks and create natural travel corridors. Interstate 90 near Livingston and the Yellowstone River valley provide clear geographic anchors for trip planning.

Terrain ranges from lower valleys around 5,000 feet to high ridgelines approaching 9,000 feet, with most of the huntable country sitting in the mid-elevation band around 6,000-7,500 feet. Dense conifer forest dominates the landscape—Douglas fir, spruce, and lodgepole pine across the slopes with occasional grassy parks and sagebrush benches breaking the timber. The rolling topography creates natural benches and saddles where vegetation transitions occur.

Early season hunting occurs in higher parks and ridges; as fall progresses, pressure pushes animals into timbered draws and lower creek bottoms where dense cover offers refuge.

The unit has over 320 miles of maintained roads, primarily connecting to Highway 191, US 287, Highway 87, and Interstate 90. Access from the north via Livingston and from the south via Gardiner and the park boundary is straightforward by vehicle. However, significant private land holdings complicate access to public ground—hunters typically stage from nearby towns and must identify legal access routes across private property or use public road rights-of-way. Pressure concentrates near main highway corridors and known trailheads; the rolling, timbered nature of the unit makes it relatively easy to find less-hunted country if willing to hike away from primary access points.

Unit 341 occupies a significant portion of the Northern Rockies front, bounded on the south by the Yellowstone National Park line and the Montana-Idaho border (Continental Divide), on the north by Interstate 90 near Livingston, and on the east by the Custer-Gallatin National Forest boundary along the Absaroka Range. The unit spans across portions of Gallatin, Madison, Park, Carbon, and Sweetgrass Counties, creating a complex patchwork of public and private land. The Boulder River and Yellowstone River drainages form major geographic divides within the unit, providing natural corridors and navigation references for hunters working the country.

The Yellowstone River flows through the unit's western edge, supplemented by the West Boulder River and Slough Creek drainages. Numerous smaller creeks including Norton, Sand, Seven Springs, Gregson, Oregon, Spring, Muddy, Elk, and Edward Creeks provide secondary water sources, though many run seasonally or diminish significantly by late fall. Scattered springs—Deer, Wire, and Continental Springs—exist throughout but shouldn't be relied upon as primary water sources without pre-season scouting.

The creek bottoms are critical moose habitat and often funnel animals during hunting season, making them key locations for planning hunts and positioning.

Unit 341 is moose country, with the rolling forest and perennial creeks providing excellent habitat for fall hunting. Early season efforts focus on calling bulls in from higher parks and ridge benches where they respond to cow calls. Mid-season, shift hunting toward creeks and drainages where bulls increasingly congregate and feed—the Seven Springs, Gregson, and Oregon Creek areas are productive.

Late season generally pushes remaining animals into thick timber and canyon bottoms, requiring patient still-hunting or tracking fresh sign in snow. Scout water sources carefully—reliable water access determines whether moose stay in an area during dry falls. The timbered terrain limits long-range glassing, making calling and drainage hunting more effective than spot-and-stalk tactics.
