Unit 17

Hoback

Rolling high country where Hoback and Greys River drainages carve through mixed forest and open ridges.

Hunter's Brief

Unit 17 sits in the transition zone between the Snake River mountains and the Hoback drainage system, with rolling terrain that climbs from around 5,800 feet to over 10,800 feet. Access is fair with 337 miles of road network threading through the unit, though road density leaves pockets of quieter country. Water exists but scattered—Hoback River anchors the southeast corner while smaller creeks and springs dot the drainages. Moderate forest coverage means glassable ridges mix with timbered slopes. This is complex terrain that rewards map study and patience.

Terrain Deep Dive

Landmarks & Navigation

Monument Ridge serves as the unit's dominant north-south navigational spine, providing excellent glassing potential from multiple vantage points. Ramshorn Peak, Clause Peak, and Lookout Mountain cluster in the northern section and offer both navigation markers and high-country terrain character. The Hoback River defines the eastern boundary but isn't the only reliable water—Halfturn Creek, Fisherman Creek, and Hunter Creek provide interior drainage navigation.

Bare Hole and Johnny Counts Flat offer distinctive terrain breaks for route planning. Cliff Creek Falls and Cliff Creek Pass add topographic detail in the western drainages. These features combined create a reasonably readable landscape without requiring constant map reference.

Elevation & Habitat

Terrain spans from roughly 5,800 feet in river valleys to above 10,800 feet on high ridges, with most country clustering in the 7,000-9,000 foot band. Lower drainages hold sagebrush and scattered conifers before transitioning to mixed forest on mid-elevation slopes. Upper elevations feature more consistent conifer coverage—Douglas fir and lodgepole—interspersed with natural openings and ridgetop parks.

The rolling topography creates a patchwork of glassable parks and timbered benches, with Monument Ridge and the cluster of summits (Ramshorn, Clause, Lookout Mountain) forming natural terrain breaks. This elevation range supports year-round habitat diversity, though seasonal migrations follow the obvious thermal cover transition.

Access & Pressure

The 337-mile road network is the unit's defining access feature, creating a moderate-pressure environment with logical entry points. Highway 191 provides straightforward access up the Hoback River drainage to Bondurant and beyond. Secondary roads branch into interior drainages, but the rolling terrain and moderate forest coverage mean roads don't penetrate everywhere equally.

This creates a realistic situation where most pressure concentrates near obvious trailheads and main drainages while side drainages and ridge country see less traffic. The terrain complexity (7.3/10) means hunters who leave established routes encounter steeper, more technical country that naturally filters out casual pressure. Fair accessibility means this isn't a remote wilderness but also isn't an easy drive-and-glass operation.

Boundaries & Context

Unit 17 forms a distinct wedge of country bounded by the Hoback Rim to the south, where Highway 191 marks the access corridor. The unit stretches from the Greys River-Hoback divide on the west through rolling ridgelines to the Snake River on the north. The landscape is anchored by three major drainages—the Hoback River running southeast, Greys River defining the western edge, and smaller creeks (Burnt, Halfturn, Snag) cutting through the interior.

The community of Bondurant sits at the confluence of Hoback and Snake Rivers, providing logical staging for access. This moderate-sized unit occupies prime transitional terrain between basin and mountain country.

Water & Drainages

Water exists but requires strategic knowledge. The Hoback River provides reliable flow along the eastern side where Highway 191 parallels its course. Interior drainages including Fisherman Creek, Hunter Creek, Burnt Creek, and Halfturn Creek run seasonally to perennial depending on location and time of year.

Scattered springs exist but aren't abundant—Astoria Mineral Hot Springs marks one known thermal feature. The rolling terrain means water tends to concentrate in the main drainage bottoms rather than dispersing across the unit. Late-season hunting could require knowledge of secondary water sources or acceptance of longer moves between reliable sources.

Spring and early summer offer better distributed water availability.

Hunting Strategy

Bear hunting in Unit 17 centers on understanding seasonal movement through elevation zones and drainage systems. Early season finds bears in lower drainages working through sagebrush and scattered cover—glassing open ridges can yield sightings. As temperatures climb, bears move upward into mixed forest and toward available water sources in creek bottoms and springs.

The Hoback and Greys River drainages funnel movement, making these corridors productive areas for stalking or positioning. Mid-to-late season hunting emphasizes higher elevations where bears feed in parks and transition zones before seasonal retreat. The rolling topography lets hunters glass extensively from ridgelines, though the moderate forest coverage means waterhole and travel-corridor hunting remains viable.

Accessing quieter terrain away from main roads increases encounter probability.
