Unit 51

Sunlight-Crandall

High alpine terrain above Sunlight Basin meets steep drainages flowing toward Clark's Fork River.

Hunter's Brief

Unit 51 is rugged high-country elk habitat spanning from the Beartooth Plateau down through tight drainages and benches. The terrain is steep and complex, with elevations climbing into alpine terrain and dropping into heavily timbered canyons. Access is fair with roughly 450 miles of road available, though much of the real hunting happens above the road network. Water is present but scattered; you'll rely on seasonal springs and creeks. This is serious terrain requiring good fitness and navigation skills.

Terrain Deep Dive

Landmarks & Navigation

The Beartooth Plateau dominates the upper unit, offering extensive glassing opportunities across alpine terrain. Cathedral Cliffs provide a dramatic visual reference and mark significant terrain breaks. Beartooth Pass and Dead Indian Pass are key navigation corridors.

The Clark's Fork River system anchors the lower drainage, with Sunlight Basin forming a major geographic focal point. Notable summits including Elkhorn Peak, Black Mountain, and Hunter Peak serve as reliable navigation landmarks visible from distance. Chain Lakes and Granite Lake offer water reference points for orientation in the high country.

Elevation & Habitat

This unit sits in true high country, with the Beartooth Plateau forming the upper backbone and elevations dropping into timbered drainages and benches. The terrain transitions from alpine meadow and talus at the highest points down through subalpine forest dominated by whitebark pine and spruce-fir, then into denser ponderosa and lodgepole stands in the lower canyons. Scattered open parks and meadows like Willow Park and Dead Indian Meadows provide elk feed throughout the elevation gradient.

The moderate forest coverage indicates a mix of open ridges, timbered slopes, and alpine terrain rather than uniform timber, creating diverse habitat for bulls moving seasonally.

Access & Pressure

Fair access means you have roughly 450 miles of road available, but the road network is selective rather than comprehensive. Morrison Jeep Trail provides the primary western access; Highway 212 skirts the northern boundary. Most roads serve as starting points rather than endpoints—the real hunting requires leaving your vehicle and climbing into the steep drainages and benches.

The steep terrain and complexity of the unit naturally limit pressure to better-prepared hunters willing to work vertical terrain. The backcountry nature of most productive country means solitude is attainable with effort.

Boundaries & Context

Unit 51 encompasses the country between Wyoming Highway 212 on the north and Yellowstone National Park on the south, bounded by the Wyoming-Montana state line to the east. The unit includes all drainages of the Clark's Fork River system, including Dead Indian Creek, Elk Creek, and Sunlight Creek drainages. This is substantial country—the boundaries capture the upper portions of several major basins including Sunlight Basin and the Box, creating a unit that spans from borderland ridge systems down into significant river drainages.

Morrison Jeep Trail (USFS Road 120) marks a key access corridor through the western portion.

Water & Drainages

The Clark's Fork River is the main water artery, with Clark's Fork itself, Dead Indian Creek, Elk Creek, and Sunlight Creek as primary drainages offering reliable flow in early and mid-season. Numerous named creeks including Silver Creek, Copper Creek, Rock Creek, and Spring Creek thread through the canyons. High-country water is more limited; springs like Brown Bear Spring and Badger Spring exist but require specific knowledge to locate.

Late-season hunting will require understanding which drainages hold water longest. The drainage network creates natural travel corridors that funneling elk movement.

Hunting Strategy

Unit 51 is elk-focused country spanning diverse elevation. Early season hunts work the high parks and ridges of the Beartooth Plateau where bulls are found in open terrain—glassing dominates. Transition to middle elevation benches and timber as summer heat and pressure push elk down.

Rut hunting exploits the drainages and timbered draws where bulls move between high summer range and lower drainages. Late season concentrates on lower canyon country where remaining snow pushes elk downslope. The vertical terrain means understanding elk migration patterns between elevations.

This unit rewards hunters who can navigate steep country, navigate drainages, and adapt to weather in exposed alpine terrain.
