Unit 350
Bull Mountain/Whitetail
Rolling forested ridges and mountain parks between Butte and Boulder with reliable elk habitat.
Hunter's Brief
Unit 350 sits in the transition zone between Butte and Boulder, featuring rolling terrain with dense timber mixed with open parks and meadows. The landscape spans mid-elevation country with solid road access via the Boulder-Whitetail Road corridor and Interstate 15 boundaries. Multiple creeks and springs provide consistent water for both hunters and game. Proximity to Butte makes it accessible, but the rolling topography and forest cover offer enough complexity to find solitude away from the main travel corridors. Expect a mix of mule deer and elk country with mountain lion possibility.

Terrain Deep Dive
Landmarks & Navigation
The Boulder-Whitetail Road provides the main navigation corridor and the unit's primary spine. Homestake Pass and Elk Park Pass offer key high points for orientation and glassing opportunities. Notable peaks including Pipestone Rock, Mount Pisgah, and Goodwin Mountain serve as visual anchors across the rolling terrain.
Whitetail Basin stands out as the largest open drainage and a logical area to focus effort. The network of named creeks—Jerry Smith, Nez Perce, International, and Moose Creek—all drain northwest and can serve as travel corridors or water sources depending on season. These features create a landscape with natural glassing points and defined drainages rather than sprawling open country.
Elevation & Habitat
The unit spans mid-elevation terrain from around 4,400 feet in the lower valleys to nearly 8,800 feet on the ridges. Dense forest dominates the higher elevations and north-facing slopes, with ponderosa pine and Douglas-fir giving way to scattered spruce-fir at the upper reaches. The real character emerges in the rolling country—numerous parks and meadows break up the timber, creating the textured landscape that supports elk.
Whitetail Basin and the various parks (Swede Park, Upper Whitetail Park, Tims Meadow) provide the high-quality meadow habitat that concentrates game. This isn't uniform forest; it's a mosaic where hunters benefit from understanding which parks hold animals at different seasons.
Access & Pressure
The unit sits right on Butte's doorstep with well-connected road access via Interstate 15 and the Boulder-Whitetail Road system. Over 619 miles of road provide solid penetration—hunters can access most drainages within a reasonable drive. This connectivity cuts both ways: easy access for legitimate hunters, but also predictable pressure from the nearby population center.
The rolling forest cover and multiple park systems allow savvy hunters to move away from obvious staging areas and into less-hammered country. Road density suggests this isn't a place to expect solitude in September, but October and later seasons should thin the crowds considerably.
Boundaries & Context
Unit 350 encompasses the forested country between Butte and Boulder in Silver Bow and Jefferson Counties, bounded by Interstate 15 to the west and Interstate 90 to the south. The Boulder-Whitetail Road forms the eastern spine, while the Boulder-Whitetail Divide creates a natural topographic boundary. The unit's western edge sits just miles from Butte, Montana's second-largest city, providing straightforward access but also potential for hunting pressure near town.
The geography here represents classic Montana foothill country—neither wilderness nor developed, but actively hunted transition zone with a working landscape feel.
Water & Drainages
Water in Unit 350 is more reliable than the sparse designation might suggest—the rolling terrain means multiple creeks flow consistently through the spring and early summer. Jerry Smith Creek, Nez Perce Creek, and the Little Boulder River system drain the unit and provide perennial flow in their main channels. Several meadows and springs including Coyote Flat Spring and Wildhorse Spring supplement the creeks, though reliability varies with season.
Homestake Lake and Delmoe Lake offer alpine water, while scattered reservoirs (Whitetail, Taylor) provide supplemental sources. The key consideration is that water concentration in meadow areas often concentrates game—a pattern worth recognizing during planning.
Hunting Strategy
Unit 350 holds a solid mix of elk, mule deer, and white-tailed deer with mountain lion as incidental opportunity. The parks and meadows are the unit's engine—they're where game concentrates regardless of season. During September rut, elk will be using the higher parks and timber edges; focus on Whitetail Basin and the ridges above Homestake Pass.
Later season transitions animals into lower valley country where white-tails dominate the brushy drainages. The rolling topography rewards glassing from high parks and passes rather than sitting in timber. Mule deer prefer the open ridges and park margins.
Water sources in parks and creeks will concentrate game during dry spells. The key to success here is moving methodically through park systems rather than grinding timber—the terrain structure naturally funnels animals into predictable zones.
