Unit 332

The Centennial Divide and Snowcrest Range form the dominant north-south backbone, with the Blacktail Mountains providing secondary ridgelines. Mooney Mountain, Benson Peak, and Antelope Peak serve as visible navigation markers from lower terrain. The Centennial and Blacktail watershed divides are critical reference lines for understanding drainage patterns.

Horseshoe Lake and Mud Lake in the higher basins, along with Lima Reservoir at lower elevations, provide water reference points. Major creeks including Sage Creek, Buck Creek, and the Gallagher Fork system cut through the terrain, marking natural travel corridors and reliable water sources for hunters.

Elevations span from around 5,000 feet in the valley bottoms to over 10,500 feet on the highest ridges, creating distinct habitat zones. Low-elevation valleys host sagebrush and grassland with scattered juniper, transitioning to ponderosa pine and mixed conifers on intermediate slopes. Higher elevations shift to lodgepole pine and subalpine fir, with alpine meadows and sparse timber on the highest peaks and ridges.

The sparse overall forest coverage means significant open country for glassing and travel, though pockets of denser timber offer thermal cover and bedding habitat in the transition zones between elevations.

The fair road network provides reasonable entry via BLM-USFS roads and Forest Service routes, though many roads are rough or seasonal. Dillon serves as the primary staging town with supplies and services. Access concentration around valley roads means initial pressure concentrates in accessible basins and lower drainages; hunters willing to pack higher onto ridges and into upper basins encounter less competition.

The terrain's complexity and scattered water sources naturally spread hunters thin. The lack of major highway access through the unit keeps pass-through traffic minimal, but the popularity of the general area means opening week sees moderate pressure.

Unit 332 encompasses the high country between Dillon and the Montana-Idaho border in southwestern Montana, spanning portions of Beaverhead and Madison Counties. The unit boundaries follow Interstate 15 north from the Idaho border, trace Jones Creek and valley roads on the east side, then run ridge divides and watershed boundaries back to Dillon. The roughly 1,400 miles of roads within the unit serve as the primary access skeleton, though the terrain's natural borders defined by watershed divides create a cohesive hunting area.

The Centennial and Blacktail Mountains dominate the landscape, with lower valleys and basins providing transition zones.

Water scarcity on ridges and open basins is the defining constraint. Major reliable sources include the Gallagher Creek system and its forks, Sage Creek, Buck Creek, and Alder Creek in the western portions. Springs are scattered but present—Hanson Spring, Whiskey Spring, and Eagle Spring warrant investigation early in your scouting.

Lima Reservoir and South Side Reservoir offer water at accessible lower elevations. The ridge divides themselves are typically dry, forcing hunters to plan moves around creek bottoms and known springs. Late-season water becomes critical; knowing which springs and creeks hold water is essential for extended high-country hunting.

Unit 332 is moose country, with the high basins, willow-lined creek bottoms, and subalpine meadows providing prime habitat. Early season hunting focuses on higher elevations where bulls use alpine meadows and transition zones; by mid-season, water sources become critical draw points as moose funnel to reliable creeks and springs. The sparse timber means glassing is productive—scan open basins and ridges for bulls moving between bedding and feed.

Late season pushes moose lower into timbered drainages and valley bottoms. Success requires patience, water reconnaissance, and willingness to hunt off the main roads; the terrain rewards hunters who scout thoroughly and understand seasonal movement patterns tied to water and elevation zones.
