Unit 30
Star Valley
Salt River drainage rolling terrain with moderate forest cover and challenging backcountry access.
Hunter's Brief
Unit 30 encompasses the Salt River drainage east of the Wyoming-Idaho border, featuring rolling terrain that transitions between open valleys and forested ridges. The country sits at moderate elevations with scattered timber across mixed habitat. Access depends heavily on a network of interior roads and drainage routes; water can be limited in places. The terrain's rolling nature and moderate forest coverage create natural corridors and glassing opportunities, though navigation requires careful attention to drainages and passes that funnel through the system.

Terrain Deep Dive
Landmarks & Navigation
The Salt River Range and Gannett Hills provide major orientation points and glassing terrain. Key summits include Mount Fitzpatrick, Prater Mountain, Stewart Peak, and Mount Wagner—each offering different vantage points across the drainage system. McDougal Pass and The Narrows serve as critical navigation features where terrain pinches and creates natural funnels.
Cottonwood Lake, Wagner Lake, and Slide Lake anchor specific drainages and provide water reference points. Multiple named creeks—Fourth Creek, First Creek, Martha Creek, and others—function as main travel corridors and hunting routes through the rolling country. Cedar Spring and Periodic Spring mark reliable water sources for strategic positioning.
Elevation & Habitat
The unit spans from low valleys near 5,600 feet to ridges exceeding 10,800 feet, creating distinct habitat zones. Lower elevations feature open sagebrush and grassland valleys with scattered aspen and cottonwood, particularly along streams like Fourth Creek and Flat Creek. Mid-elevations transition into coniferous forest with ponderosa pine and Douglas fir interspersed with meadows and parks.
Higher terrain above 9,500 feet becomes increasingly dense timber with subalpine characteristics. The rolling topography means no truly steep cliffs dominate, but rather a series of ridgelines and canyon systems that create natural travel corridors and viewing points across varying vegetation zones.
Access & Pressure
A connected network of 680 miles of roads provides substantial interior access, distributed across lower and middle elevations throughout the unit. This road density creates multiple staging areas and entry points, particularly from Afton and other valley communities. The rolling terrain and moderate forest means roads aren't always obvious, and navigation requires map skills.
Connected access suggests moderate to fair hunting pressure concentrated around road-accessible drainages and valleys. Higher-elevation terrain away from established roads offers solitude but requires backcountry travel. The terrain complexity (7.0/10) indicates that while accessible, the rolling country and drainage system are intricate enough to reward hunters who understand the landscape's structure.
Boundaries & Context
Unit 30 is defined by the Salt River drainage basin east of the state line, a natural boundary that separates Wyoming from Idaho. The unit encompasses the entire eastward-flowing Salt River system, creating a defined but geographically complex area that spans rolling foothills and mid-elevation mountains. Major reference points include the towns of Afton and Auburn to the south, with smaller communities like Grover, Osmond, and Fairview scattered through lower valleys.
The Salt River Range forms the western backbone, while the Gannett Hills define portions of the interior. This moderate-sized unit contains significant elevation relief and multiple drainage systems that converge toward the main river channel.
Water & Drainages
The Salt River is the dominant water feature, flowing east through the unit's core. Numerous tributaries including Fourth Creek, First Creek, Martha Creek, and Flat Creek provide seasonal and year-round flow at various elevations. Wagner Lake, Cottonwood Lake, Slide Lake, and several smaller lakes provide water sources, though availability varies seasonally.
The State Line Ditch, Baker Ditch, and other irrigation infrastructure along lower elevations indicate manipulated water flows in valley bottoms. Higher-elevation springs like Cedar Spring and Periodic Spring can be unreliable. Overall water is limited compared to wetter mountain ranges, requiring hunters to plan water access carefully and understand seasonal flow patterns in the drainage network.
Hunting Strategy
Unit 30 is historically associated with black bear, found throughout the rolling terrain and forested ridges. Productive strategy depends on understanding elevation migration patterns—bears move between valley bottoms in spring and lower elevations for berries and mast in late summer and fall. The rolling foothills and creek systems create ideal habitat, with bears following timber edges, avalanche slopes, and drainages where food concentrates.
Early season hunting focuses on lower elevations in valley systems like those around Broad Hollow and the various named canyons. As season progresses, bears move higher into the timbered ridges. The moderate forest coverage means glassing from ridgelines and using natural openings to locate bears; the rolling terrain requires systematic coverage of drainage systems rather than long-distance spotting.
