Unit 34
Upper Powder River
High-country basin and ridge country bridging the Bighorn Mountains with scattered timber and limited water sources.
Hunter's Brief
Unit 34 spans medium-elevation terrain with sagebrush parks, scattered pine and aspen, and significant elevation variation across rolling ridges and draws. Access is limited to rough forest service roads and county routes that require high-clearance vehicles in many sections. Water is scattered and seasonal—springs and small creeks exist but aren't reliable year-round. The unit's terrain complexity and size reward hunters willing to venture beyond main roads, though this also means less pressure in the backcountry.

Terrain Deep Dive
Landmarks & Navigation
Major ridge systems—including Box Elder, Robins, Ferris, and Poison Weed ridges—provide natural navigation corridors and elevated glassing vantage points. Dull Knife Pass and Powder River Pass offer strategic passes through the ridgeline. Named valleys like Starvation Draw, Spring Draw, and Pass Creek Canyon funnel water and wildlife movement.
Hole-in-the-Wall Lake anchors a notable basin area. The T A Hills and scattered summits (Gobblers Knob, Gardner Mountain, Eagles Trap) serve as recognizable landmarks. These features help orient hunters in terrain that can feel maze-like once you're off main roads.
Elevation & Habitat
Terrain transitions from lower sagebrush valleys around 4,600 feet to alpine ridges exceeding 10,400 feet. Mid-elevation benches between 6,500 and 8,500 feet host mixed conifer forests interspersed with sagebrush parks and grass meadows—classic elk country. Lower elevations feature open rangeland with scattered juniper and mountain mahogany.
The highest ridges support spruce-fir and wind-carved timber. This vertical relief creates distinct seasonal habitat use: lower country provides winter range and early-season access, while mid and high ridges offer refuge during warmer months. The patchwork of forest and open parks creates glassing opportunities at multiple elevations.
Access & Pressure
Over 400 miles of roads penetrate the unit, but most are rough forest service routes requiring high-clearance vehicles and limiting traditional access. The main staging points are along I-25 and Highway 191 corridors, particularly near Barnum and Mayoworth. Crazy Woman Canyon Road and the Hazelton/Gold Mine Road network provide western access but deteriorate quickly into rougher terrain.
The combination of limited road density, difficult vehicles access, and vast terrain area means hunting pressure concentrates along main corridors and lower elevations. Backcountry travel on foot becomes necessary to escape crowds, but terrain complexity rewards those willing to work for it.
Boundaries & Context
Unit 34 anchors the eastern slope of the Bighorn Mountains, bounded by Interstate 25 on the east and ranging west through the foothills toward Barnum and the higher ridges. The unit encompasses everything between US Highway 16 to the north and Wyoming Highway 191 to the south, wrapping around scattered communities like Mayoworth and Hazelton. This expansive territory spans from lower rangeland into genuine mountain terrain, with access points concentrated along the unit's eastern perimeter via I-25 and Highway 191. The western portions push into rougher country where forest service roads dominate.
Water & Drainages
Poison Creek drains a significant portion of the unit and provides reliable water in its main channel during hunting season. North Fork Red Fork Powder River, North Horse Creek, and Willow Creek offer perennial flow through major drainages. Smaller creeks—Pass Creek, Pole Creek, Sawmill Creek, Steel Creek—run intermittently and depend on seasonal snowmelt.
Numerous documented springs (Middle Spring, Billy Creek Spring, Hammond Spring, Cottonwood Spring, and others) exist but shouldn't be counted on without local knowledge of flow timing. The many reservoirs and stock tanks are typically lower-elevation structures that support cattle operations; some may be dry by late season. Water scarcity in higher elevations makes drainage-based hunting necessary.
Hunting Strategy
Unit 34 is elk country across all elevations, from lower foothill herds to high-ridge populations. Early season (September) finds elk transitioning through mid-elevation parks and ridge saddles as they move between summer high country and winter range. The rut (September-October) concentrates bulls in timber pockets near parks and drainages—glassing ridge edges and listening in aspen stands yields opportunities.
Late season pushes remaining elk to lower elevations and protected valleys. Success depends on water knowledge: locate reliable springs and creeks, then glass and glass again. The terrain's complexity and limited access mean patience and off-trail competency matter more than proximity to roads.
Elk here respond well to traditional calling and routing patterns tied to thermal cover and water access.
