Unit 10A-4
Steep, timbered terrain between the Clearwater and Salmon Rivers with limited but critical water sources.
Hunter's Brief
This is challenging, heavily forested country spanning the divide between two major river systems in central Idaho. Elevation ranges from low valley floors to mid-elevation ridges, with thick timber covering most terrain. Access is fair via Forest Service roads and old wagon routes, though the steep topography makes travel deliberate. Water is scattered—springs and creeks exist but require knowing where to find them. Moose habitat here demands patience and local knowledge. The country rewards hunters willing to work steep slopes and navigate dense forest.

Terrain Deep Dive
Landmarks & Navigation
Castle Rock, Hemlock Butte, and Windy Peak serve as recognizable high points for orientation on this steep terrain. Stony Creek and its western fork cut through the unit as major drainages—these creeks are navigation tools and travel corridors. Freezeout and Coopers Saddles mark passes between ridges and become reference points during travel.
Hemlock Spring and Freezeout Spring offer reliable water in upper country, though their locations require advance knowledge. Pinchot Marsh provides another water reference in the northern section. These landmarks matter less for glassing and more for finding your way through continuous timber and staying oriented on steep ground.
Elevation & Habitat
Terrain spans from low river valleys around 1,500 feet to mid-elevation ridges topping out near 6,300 feet, with most country falling in the 3,000- to 4,500-foot zone. Dense forest dominates the unit—ponderosa pine and Douglas fir at lower elevations transition to grand fir and spruce as elevation increases. Meadows and openings appear scattered throughout, particularly around Stony Creek Meadows and Hemlock Butte area, breaking the otherwise continuous timber.
This is moose habitat where forest and water intersect. The steep terrain means timber can feel oppressive, with visibility often limited to 50 yards or less.
Access & Pressure
Fair road access via Forest Service routes and old wagon roads provides entry points, though the dense forest and steep terrain naturally limit pressure compared to more open country. Forest Service Road 444 (Square Mountain-Gospel Hill Road) and Road 221 (Elk River Road) offer main access corridors. State Highway 13 and U.S. 95 provide highway access to unit boundaries.
However, steep slopes mean that even accessible areas see modest hunting pressure due to the physical demands of moving through thick timber and rough ground. Most traffic concentrates near road ends; the interior remains relatively quiet for hunters willing to climb and navigate blindly through forest.
Boundaries & Context
Unit 10A-4 occupies the rugged divide country between the North Fork and South Fork Clearwater Rivers, extending south toward the Salmon River system. The unit encompasses portions of Shoshone and Clearwater Counties, bounded by State Highway 13 to the west and U.S. 95 near Cottonwood to the northwest. Dworshak Reservoir forms part of the eastern boundary, while the Salmon River marks the southern extent.
This is transitional terrain where river valleys give way to steep, timbered ridges—a landscape shaped by the collision of two major drainage systems.
Water & Drainages
Water exists but demands effort to locate. Stony Creek and Timber Creek are primary drainages with reliable flow, particularly in upper sections. Secondary creeks—Trail Creek, Trapper Creek, Trestle Creek—branch throughout the unit and provide water access but may run low by mid-season.
Springs, particularly Hemlock Spring and Freezeout Spring, offer dependable sources in upper country but aren't abundant. This is water-limited terrain where knowing creek locations and spring positions becomes critical for both hunting strategy and survival. Early season offers more reliable flow; late season may require range-finding to reliable springs.
Hunting Strategy
Moose hunting here revolves around water and timber. This is calling and bugling country in early season when bulls respond to cow calls, but location matters—focus efforts on creek drainages, particularly Stony Creek and its western fork, where moose gather to feed and drink. Glassing means limited visibility, so hunting depends on moving quietly through timber and listening for breaking brush or water sounds.
Mid-elevation meadows around Hemlock Butte and upper Stony Creek Meadows hold promise during transition seasons. Know water locations in advance—creeks and springs dictate where moose concentrate. The steep terrain favors hunters comfortable moving slowly and quietly uphill through timber rather than hunters expecting long sight lines.
Morning and evening, focus on creek bottoms and meadow edges.
