Unit 73A

The Deep Creek Mountains provide the unit's geographical spine and reference point for navigation. Major drainage systems—West Fork Bannock Creek, West Fork Sunbeam Creek, Sawmill Creek, and Moonshine Creek—serve as natural corridors and water highways through the terrain. Named peaks including Bannock Peak, Buck Peak, and Moonshine Peak offer glassing vantage points.

Waylett Canyon, Box Canyon, and Hunter Canyon represent significant drainages where terrain concentrates and wildlife movement funnels. Lower elevation reference points like Colson Basin and Howard Flat help orient hunters in the open country. These landmarks, combined with the spring network throughout the unit, provide hunters with reliable navigation anchors.

The unit spans significant elevation range, from sagebrush-dominated basins around 4,400 feet to forested peaks exceeding 8,700 feet. Lower elevations support open sagebrush benches and scattered low-elevation valleys where water sources concentrate. Mid-elevation slopes hold sparse to moderate conifer cover—primarily Douglas-fir and limber pine mixed with sagebrush parks.

Upper ridges and canyon bottoms support denser timber and riparian vegetation critical for moose. The sparse forest designation reflects the overall character: much of the unit remains open country, making water sources and drainage bottoms the true focus for hunting.

The unit benefits from a connected road network totaling nearly 800 miles of roads, providing fair access throughout most of the terrain. County roads and Forest Service roads penetrate major drainages and connect to Highway 37 and Interstate 86, allowing hunters to establish camps and stage into the interior. The rolling terrain and sparse forest mean that while initial access is straightforward, hunters quickly move into country where terrain navigation matters more than road access.

The combination of connected but not excessive road density and varied elevation suggests moderate hunting pressure concentrated near convenient trailheads and lower-elevation water sources. Interior country rewards patience and willingness to penetrate deeper drainages.

Unit 73A occupies a substantial portion of south-central Idaho's lower mountains, bounded by the Idaho-Utah state line on the south and east, with State Highway 37 and Interstate 86 forming sections of the northern and western boundaries. The unit encompasses portions of three counties—Bannock, Oneida, and Power—creating a geographically diverse area that transitions from basin floors to moderate mountain terrain. The Deep Creek Mountains form a significant central feature.

Highway access is straightforward, making this unit logistically accessible from regional towns, though the interior requires understanding the drainage-based terrain.

Water defines hunting opportunity in Unit 73A. Permanent streams including West Fork Bannock Creek, West Fork Sunbeam Creek, and Sawmill Creek flow through major drainages year-round, providing reliable water sources. A substantial spring system—including Waylett, Study, Buck, Garden, Officer, Sagehen, Sawmill, Indian, and Pine springs—supplements stream flow, particularly important in upper basin areas. The unit's limited overall water abundance means concentrating effort around reliable drainage bottoms where moose naturally congregate.

Upper Stump Canyon Reservoir provides water in the southern section. Early and late season hunting may face water scarcity in open benches; mid-season offers more options as snowmelt feeds drainages.

Unit 73A is moose country, and success hinges on understanding water and drainage systems. Moose in this terrain concentrate in riparian vegetation along permanent water—focus hunting effort on West Fork Bannock Creek, West Fork Sunbeam Creek, Sawmill Creek, and other named streams where browse and water overlap. Early season hunting can be productive in mid-elevation draws where sparse timber provides cover and forage; late season may require dropping to lower elevation drainages as snow accumulates above 7,000 feet.

The spring network is valuable for establishing base camps and glassing benches adjacent to water. Use the rolling terrain to glass open sagebrush areas, then move into canyon bottoms where moose actually live. Expect to hike beyond the road network to find unpressured animals.

The unit's complexity score reflects terrain navigation demands rather than extreme difficulty—methodical, water-focused hunting produces results.
