Unit 4

Lookout Mountain and Elk Peak anchor the high ridge system for glassing and orientation. The Bighorn Mountain Divide running north-south forms the backbone, crossed by Powder River Pass and Granite Pass. Finger Rock, Preacher Rock, and Dome Rock provide visual references in the middle country.

Key drainages include Graves Creek, Gloom Creek, and Game Creek—useful for downhill navigation and water-finding. Duncan Lake, Sibley Lake, and the Stull Lakes cluster offer navigation markers and potential water sources in the high parks. The park systems themselves—particularly Long Park, Walker Prairie, and Big Goose Park—break the forest and aid route-finding in otherwise complex terrain.

The unit transitions dramatically from semi-arid foothills around 4,000 feet to alpine terrain approaching 13,100 feet. Lower elevations feature open parks, grasslands, and scattered ponderosa pines. Mid-elevations (around 7,000–8,500 feet) support denser forest with meadows and aspen pockets.

High-elevation country above 9,500 feet consists of subalpine spruce-fir forest interspersed with wind-exposed ridges and tundra-like vegetation. The parks—Coffeen, Medicine, Webber, and others—form critical meadow systems throughout the mid-elevation zone. Forest coverage is moderate overall, with significant open country in the park systems and ridgetop areas.

The unit has fair road access with about 1,600 miles of road scattered throughout, but most are Forest Service roads reaching trailheads rather than penetrating core terrain. U.S. Highway 16 crosses the unit through the Bighorn Mountains, and U.S. Highway 14 follows the northern ridge. The Hazelton Road and various Forest Service roads provide access to the western drainages and park systems.

Population pressure concentrates near Buffalo and Sheridan; much of the interior remains relatively quiet. The terrain complexity (8.2/10) means that even accessible areas require navigation skills. Hunters willing to move beyond immediate road access find solitude in the vast park systems and remote drainages.

Unit 4 encompasses the Bighorn Mountains and their foothills in north-central Wyoming, bounded by Interstate 90 near Ranchester on the north, Interstate 25 on the east, and the Bighorn National Forest boundary along its western edge. The unit runs roughly 40 miles north-south and 30 miles east-west, encompassing high mountain terrain, extensive park systems, and lower-elevation basin country. Major landmarks like Powder River Pass and Granite Pass on the mountain divide form natural reference points.

The populated areas of Buffalo, Sheridan, and Story sit near the unit's boundaries but don't penetrate deep into the interior.

Water is limited and seasonal across much of Unit 4, requiring serious scouting. Reliable sources include the major creeks on the western slope: Graves Creek, Owen Creek, and the South Fork Little Tongue River. The park systems hold seeps and small springs after runoff, but many dry significantly by mid-summer.

Higher-elevation lakes like Duncan Lake, Sibley Lake, and the Sawmill Lakes provide reliable water in the subalpine zone during hunting season. Lower elevations rely on scattered springs and seasonal runoff—Cole Spring, Fox Cabin Spring, and Mosier Springs are marked but not necessarily dependable. Hunters moving through the parks must plan water carefully, especially on ridge systems.

Unit 4 supports black bear populations in the Bighorn Mountains, with habitat concentrated in the moderate-to-dense forest zones between 7,000 and 10,000 feet. Spring hunting targets bears emerging from winter in the lower parks and south-facing slopes where early vegetation greens up. Early season (late summer) is productive in the high parks and alpine meadows where bears feed on berries and roots.

Fall hunting focuses on bears moving through transition zones between summer high-country range and lower-elevation winter habitat. Key strategy: glass the open parks for movement patterns, then work brushy creek drainages and forest edges where bears forage. Water sources concentrate bears in dry periods.

Terrain complexity demands good navigation—getting lost on the mountain divide accomplishes nothing.
