Unit 380

Canyon Ferry Reservoir dominates the southern and eastern landscape as a major reference point and access hub. The Elkhorn Mountains and higher ridges to the west (including summits like Burnt Mountain, High Peak, and Emerson Peak) provide glassing vantage points and navigation landmarks. Crow Peak near the Boulder-Missouri Divide marks the western extremity.

Major creeks—including Warm Springs, Crow Creek, and Rattlesnake Creek—flow through named valleys and canyons, serving as both travel corridors and water sources. The Spokane Hills on the northern edge offer additional terrain breaks. These features create natural organization for planning daily movements.

Terrain rises gradually from roughly 3,750 feet at the Missouri River to over 9,300 feet on the highest ridges near the divide. Lower elevations host open sagebrush grasslands and cottonwood draws typical of Montana foothills, while mid-elevation slopes support ponderosa and Douglas-fir mixed with grassland parks. Upper terrain transitions to higher-elevation forest and meadow complexes.

The combination creates diverse habitat zones—productive lower grasslands for early season, timber cover and parks for mid-elevation hunting, and high country for late season. Multiple parks and flats (Casey Meadows, Horsethief Park, Elk Park among others) suggest good elk and pronghorn habitat at various elevations.

The unit benefits from connected road access totaling over 600 miles, with USFS Road 4031 and Road 424 providing trunk routes through the western terrain. US Highway 12-287 and Route 518 serve the eastern portion near East Helena and Montana City. Road density suggests well-established access corridors, though the moderate complexity rating indicates terrain breaks that create hunting opportunity away from main routes.

Proximity to Helena area (via East Helena and Montana City) likely means moderate weekend pressure on accessible areas, particularly near Canyon Ferry Reservoir. Upper elevations and western drainages may see less traffic, especially mid-week.

Unit 380 occupies roughly 500 square miles across Broadwater, Lewis and Clark, and Jefferson Counties in central Montana. The Missouri River and Canyon Ferry Reservoir form the eastern and southern boundaries, while the Boulder-Missouri Divide runs along the western edge near Crow Peak. Interstate 15 clips the unit's southwestern corner, and US Highway 12-287 provides eastern access through East Helena.

The unit encompasses everything from reservoir shoreline near Townsend to higher terrain approaching the Elkhorn Mountains, with scattered communities like Montana City, Winston, and Louisville sitting within or near unit boundaries.

Water abundance defines this unit. Canyon Ferry Reservoir is perennial and extensive along the southern boundary. The Missouri River enters from the north and flows south.

Warm Springs Creek system (North and Middle Forks) drains the western terrain, while Crow Creek, Maupin Creek, and Rattlesnake Creek provide reliable flows through their respective drainages. Multiple named springs—Kelley, Merritt, Bomar, Graham, Antelope, and Church Springs—dot the unit. This water diversity means hunters can access reliable water sources throughout most of the unit during all seasons, reducing logistical pressure and allowing flexibility in route planning.

Pronghorn is the listed species, indicating the unit's primary game value sits in lower and mid-elevation grassland and sagebrush habitat. Early season hunting focuses on open country and park areas at lower to mid-elevations—places like Elk Park, Horsethief Park, and the various flats surrounding main drainages. Glassing from higher ridges and buttes can locate animals using open terrain.

Water sources provide natural gathering points during early season. Terrain complexity suggests that while roads provide access, getting off main routes into valleys and along creek bottoms offers advantage. The reservoir and river also concentrate some activity.

Late season may push animals toward lower country and protected draws. Mixed private ownership likely requires careful route planning and access negotiation in populated areas, but abundant water and diverse habitat support sustained hunting throughout the season.
