Unit 56

The Sublett Range dominates the eastern landscape, with Eyrie Peak and Cedar Ridge serving as visible navigation markers. Stone Hills, Horse Butte, and the Massacre Rocks form recognizable features across the middle country. The Meadows and Saddle Horse Basin are prominent basin features useful for orientation.

Heglar Canyon, Twin Canyons, and Glen Canyon provide drainage corridors and natural travel routes. Summit Springs Pass and The Meadows Divide mark important breaks in the ridge systems. These landmarks are distinctive enough to navigate by and accessible for glassing vantage points.

Elevations span from around 4,200 feet in the lower basins to 7,500 feet on the ridges, but most of the unit sits in the 5,000-to-6,500-foot band—open country dominated by sagebrush, bunch grasses, and isolated stands of juniper. The terrain transitions from broad, flat basins to rolling ridge systems rather than steep mountains. Forest cover is sparse throughout; the landscape is characterized by vast sagebrush expanses interrupted by canyon bottoms with scattered aspen and willow.

This open terrain offers excellent visibility for spotting and glassing, with minimal heavy timber to contend with.

Over 1,500 miles of road traverse Unit 56, and while exact density is unavailable, the road network is clearly well-developed across the sagebrush country. Interstate 84 and Highway 37 provide major entry corridors; smaller ranch roads and irrigation access routes branch throughout. This connected road system means the unit accommodates vehicle travel easily, reducing pack-in requirements.

However, the vast, open terrain means vehicles can access many locations, so finding solitude requires moving away from staging areas near roads and water. The straightforward topography and good road access keep pressure moderate in accessible basins, with less-visited country available on the ridges and in smaller drainages.

Unit 56 encompasses portions of Cassia, Oneida, and Power counties in southeastern Idaho, spanning from Interstate 84 on the north down to the Idaho-Utah state line. The unit's eastern boundary follows Highway 37 near Yellowstone Park, while the western side drops into Nevada near Monida Pass. This is substantial country—the boundaries encompass the high-desert region between the Snake River Plain and the Sublett Range, creating a landscape of basins, valleys, and modest ridges.

The unit sits at the convergence of several geographic zones, making it distinct from both northern mountain units and southern desert country.

Water is the limiting factor in Unit 56. Sublett Creek and its forks are the most reliable drainages, running year-round through lower canyon bottoms and providing consistent water in the middle and southern portions of the unit. Warm Springs Creek, Station Fork, and Indian Fork offer additional drainage corridors. Scattered springs—Butler, Clint Palmer, Hot Springs, Mud Spring, and others—dot the unit and are critical for hunting strategy.

Stone and Sublett reservoirs, along with Pine Creek Reservoir, provide artificial water sources. In the open basin country, proximity to water can dictate hunting location, particularly during early season when moose concentrate near riparian areas.

Moose in Unit 56 are found in riparian habitat and wet meadows within the sagebrush landscape—primarily along Sublett Creek, Warm Springs Creek, and other reliable drainages, plus around springs and reservoir areas. Early season (September) focuses on calling and glassing drainage bottoms and wet aspen thickets where bulls concentrate before the rut. Rut timing shifts focus to calling in more open country, using the sagebrush basins and ridges.

Late season (November) pushes moose back to reliable water and lower elevations as snow accumulates on the ridges. The open terrain favors spot-and-stalk tactics; use ridge tops and distant vantage points to glass broad basins for feeding moose, then work creek bottoms and wet areas as primary hunting zones.
