Unit 338
3
Sprawling foothill and basin country between the Yellowstone and Crazy Mountains, anchored by working ranches.
Hunter's Brief
Unit 338 covers rolling benchlands and narrow valleys split between the Bridger, Gallatin, and Crazy mountain ranges. This is working ranch country mixed with public access challenges—relatively flat terrain with moderate timber and limited water sources. The Yellowstone River forms a natural eastern boundary; Interstate 90 cuts through the southern portion. Access is fair but scattered; most hunting involves navigating around private parcels and identifying public ground. Pronghorn are the primary target, favoring the open basins and benches.

Terrain Deep Dive
Landmarks & Navigation
The Bridger Mountain Divide and Bangtail Ridge form prominent south-boundary features useful for orientation. The Hogback, Bald Ridge, and Battle Ridge provide navigation references across the unit's interior. Wallrock Cliff and Wallrock Basin anchor the western section; the Crazy Mountains define the north.
Cottonwood Bench and numerous smaller benches structure the terrain. Major drainages—Sixteenmile Creek, Cottonwood Creek, and the Yellowstone River—serve as linear references. Fairyland Lake and Cottonwood Reservoir offer modest water landmarks in otherwise limited-water country.
Elevation & Habitat
Terrain spans from roughly 4,400 feet in the river valleys to over 10,400 feet on the high divides, with most hunting activity concentrated in the mid-elevation benches and basins between 5,500 and 7,000 feet. Lower elevations feature sagebrush and grassland typical of ranching country. Mid-slopes support scattered ponderosa and Douglas-fir creating a mosaic of open parks and light timber.
Higher ridges and divide country transition to denser conifer forest. The moderate forest coverage and predominantly open basins create good glassing country, though scattered timber patches require careful stalk planning.
Access & Pressure
Over 1,100 miles of roads exist within or bordering the unit, but access is complicated by checkerboard private ownership—the badges indicate few public lands despite the vast area. Most roads serve ranch operations; public hunting access requires identifying BLM parcels or negotiating private ground. Pressure concentrates near Livingston and along Interstate 90 corridor; interior basins and upper drainages see fewer hunters due to access restrictions.
Fair accessibility suggests some public routes exist, but success depends on detailed maps showing public land boundaries and legal access points rather than casual roaming.
Boundaries & Context
Unit 338 encompasses rolling country in Gallatin, Meagher, and Park Counties, bounded by the Sixteenmile Creek drainage on the west, the Crazy Mountain Divide to the north, the Yellowstone-Gallatin Divide including Bangtail Ridge to the south, and the Yellowstone River near Livingston to the east. Interstate 90 crosses the southern edge near Bozeman Pass. The unit sits in the transition zone between mountain ranges, creating a patchwork of exposed ridges, basin floors, and narrow drainages.
Livingston and Clyde Park serve as reference points for orientation and resupply.
Water & Drainages
Water sources are genuinely limited despite the Yellowstone River forming the eastern boundary. Sixteenmile Creek and its forks drain the western terrain; Cottonwood Creek runs north through ranching areas. Most perennial water concentrates in these main drainages and scattered springs on the divide country.
Small reservoirs and historic lakes (Lone Lake, Ainger Lake) provide minimal reliable sources. Hunters must plan water strategy carefully, as many side drainages run seasonally or dry by mid-summer. The complexity and limited sources make thorough scouting essential before heading into interior basins.
Hunting Strategy
Pronghorn are the unit's primary focus, thriving on the open basins and benches where visibility is excellent. Early season means hunting lower elevations and valley floors as animals use established bedding areas and water sources. As pressure builds, pronghorn migrate to higher benches and more broken country.
Glassing from ridgetops like the Hogback and Bald Ridge covers miles of habitat; most stalks require precision rifle work across open terrain. Success hinges on finding legal public access, then glassing extensively to locate feeding groups during morning and evening hours. Water sources become critical late in the season; positioning near limited reliable sources increases encounter odds.
Terrain complexity and private land checkerboard make pre-hunt reconnaissance non-negotiable.
