Unit 340

The Highland Mountains provide the dominant ridge system running north-south through the unit's core, with White Pine Ridge, Brazil Ridge, and Big Ridge offering vantage points for scanning country. McCartney Mountain and Mount Humbug serve as recognizable summits for orientation. Pipestone Pass and Steels Pass cut through the high country and mark natural travel routes.

Buffalo Jump cliff band provides a notable terrain break. Several reservoirs including Basin Creek and Upper Reservoir, plus scattered lakes like Emerald Lake, concentrate water and wildlife in specific drainages. The numerous named ridges—Hogback, Roaring Brook Ridge, Pigeon Creek Ridge—create the terrain's underlying skeleton and assist navigation in this vast country.

The unit spans from low valley bottoms around 4,400 feet to alpine terrain above 10,000 feet, though most productive hunting sits in the mid-elevation band between 5,500 and 8,500 feet. Lower valleys support sagebrush grasslands and scattered cottonwood riparian corridors. As elevation climbs, Douglas fir and lodgepole pine take hold on north-facing slopes, while drier south-facing aspects remain open grass or scattered juniper.

Upper elevations transition to subalpine fir and limber pine. The moderate forest coverage means significant open country—ridges, benches, and park areas intersperse the timber, creating natural glassing and travel corridors. Habitat diversity supports multiple species but isn't uniformly productive across the unit.

A connected road network totaling over 1,500 miles provides reasonable vehicle access throughout the unit, but most routes are secondary roads rather than highways. Routes 41, 55, and local county roads allow hunters to stage from established towns (Dillon, Butte, Whitehall) and penetrate into the country via various gulches and canyons. The trade-off: good road access means predictable human pressure along the main drainages.

The vast terrain complexity (7.2/10) suggests that while entry points are accessible, the actual country is big enough to reward those willing to hike beyond the initial parking areas. Private land interspersion around settled areas creates access complications, but public ground is huntable if you work the boundaries. Early season pressure tends to concentrate near roads; late season often thins out as hunters leave.

Unit 340 encompasses a large swath of southwestern Montana stretching from Dillon north through Whitehall and west to the Butte area, covering portions of Beaverhead, Madison, Jefferson, and Silver Bow counties. Interstate 15 and Interstate 90 form the western and northern boundaries, while Route 41 and Route 55 define the eastern margins. The unit is anchored by the town of Dillon to the south and includes the Butte-Silver Bow area to the northwest.

This is settled country with a patchwork of public and private land, though substantial public acreage remains huntable. The broader geography places it in the upper Beaverhead River drainage system.

Water is limited and unevenly distributed across the unit. Several productive streams anchor hunting—Lost Creek, McCartney Creek, MacLean Creek, and Moose Creek drainages provide reliable flow and riparian habitat attractive to moose. Birch Creek and Stone Creek offer secondary options.

The problem is spacing: long stretches of ridge country separate these watercourses. Numerous springs scatter across the unit (Moose Camp Spring, Mill Spring, Limekiln Spring, Warm Spring among them), but they're not dependably reliable during dry years. Basin Creek Reservoir and Upper Reservoir concentrate water seasonally.

Successful hunting requires scouting water sources ahead of time and understanding seasonal patterns—early season springs may dry by fall, forcing game to remaining perennial sources.

Unit 340 is moose country, and the hunting approach revolves entirely around water. Moose key on riparian corridors and willow stands where they feed during summer and fall. Focus on the named creek drainages—Lost Creek, McCartney Creek, Moose Creek—particularly where they expand into beaver ponds or side-channel wetlands.

Early season (September) finds bulls responding to calls in cool mornings; focus on accessible water near the road network first, then push into backcountry drainages if pressure permits. Mid-season bulls are in rut; hunt the same water sources but during mid-day when bulls move. Late season (November) concentrates on the most reliable, lowest-elevation water as higher country freezes up—Birch Creek and Stone Creek drainages often hold animals into late fall.

Glassing from the ridge systems locates animals, but the actual hunting happens in the bottoms. Scout springs and reservoirs beforehand; water access often determines whether a drainage holds moose or sits empty.
