Unit Siouxon

Indian Heaven Basin anchors the eastern portion and offers a major geographic reference for navigation and hunting strategy. The summits—Gumboot Mountain, Lava Butte, Termination Point, and Timbered Peak—serve as reliable landmarks visible from lower drainages and useful for ridge-top glassing. Howe Ridge and Horseshoe Ridge provide elevated travel corridors with sightlines into the valleys below.

The Wart and Cougar Rock are smaller but distinctive features for confirming position in the timber. Twin Butte and Paradise Hills orient hunters in the central ridges where roads converge.

The unit spans from 226 feet at Yale Lake rising to 5,820 feet on upper ridges, with median elevation around 2,700 feet. Dense conifer forest dominates throughout—primarily Douglas-fir and western hemlock in the lower valleys, transitioning to true fir and hemlock on cooler slopes above 3,000 feet. Scattered meadows and prairie pockets like Two Times Four Prairie and McClellan Meadows break the forest canopy, providing open glassing terrain.

The rolling topography creates countless benches and sidehills where forest structure changes based on aspect and prior disturbance, offering varied hunting prospects.

Nearly 500 miles of USFS roads offer substantial coverage, though the dense forest and rolling terrain limit how accessible any single spot truly feels. Main entry points include USFS Road 90 from the Eagle Cliff bridge area, Road 51 (Curly Creek Rd) in the east, and Wind River Rd/Road 30 corridors. Sunset Falls via Green Fork provides western access.

The fair accessibility rating reflects that while roads exist, the thick timber means foot travel matters more than proximity to a trailhead. Popular pressure likely concentrates near main road junctions and historic camping areas; exploring secondary drainages rewards those willing to leave the roads.

Siouxon anchors the north fork of the Lewis River drainage in Skamania County, bounded by Yale Lake and the Yale Dam to the southwest and Swift Reservoir to the northeast. The unit's extensive perimeter traces USFS roads and creek drainages—Canyon Creek and North Siouxon Creek form natural corridors through the heart of the country. Multiple valleys (Paradise Valley, Pete Gulch, Poison Gulch) dissect the rolling terrain, creating distinct hunting areas.

The unit encompasses roughly 486 miles of maintained roads providing reasonable access from several entry points, though private inholdings require route planning.

Yale Lake and Swift Reservoir frame the unit's boundaries and create reliable water access at lower elevations. Canyon Creek, North Siouxon Creek, and Green Fork drain the major valleys and run consistently through the season. Numerous springs—Bubbling Mike Spring, Tyee Springs, Summit Spring, Lost Creek Spring—and smaller lakes (Rock Lake, Little Rock Lake, Acker Lake, Soda Peaks Lake, Sheep Lakes) scatter throughout the ridges.

This moderate water abundance means hunters can plan strategies around established drainages rather than being constrained by scarcity. Layout Creek and Wildcat Creek provide secondary drainage corridors for exploration.

Siouxon is black bear and mountain lion country defined by dense forest and reliable water. For bear, spring hunts focus on emerging bears using the lower valleys and meadow edges; late summer and fall shift to berry terrain on ridge slopes above 3,500 feet where huckleberry fields and feed areas develop. Lions hunt the same corridors—canyon bottoms and drainages where deer concentrate—making Canyon Creek, North Siouxon Creek, and the Paradise Valley drainage prime focus areas.

Glassing meadows and open ridges early and late in the day, then working timber benches during midday, suits the mixed terrain. Success depends on reading sign in dark timber and understanding how these predators use elevation transitions.
