Unit Quilomene

Cape Horn's prominent cliffs provide unmistakable visual reference from throughout the unit and serve as a natural barrier and landmark for navigation. Whiskey Dick Mountain and Hult Butte offer glassing vantage points over surrounding country. Major drainages—Quilomene Creek, Perkins Fork, and Brushy Creek—serve as travel corridors and water sources that concentrate game movement.

Colockum Pass marks the main northern entry point. These features create a logical framework for breaking country into manageable sections and planning daily hunting patterns without requiring extensive navigation.

Terrain rises from 500 feet at the river to above 5,300 feet on inland ridges, creating distinct habitat bands. Lower elevations feature open sagebrush flats and grassland benches typical of the Columbia plateau. Middle elevations transition to scattered ponderosa and juniper woodlands mixed with shrubland.

The upper portions add denser timber and rocky outcrops. This vertical compression across relatively compact terrain creates predictable elevational movements—wildlife shift between riparian corridors and mid-slope cover depending on season and pressure. The sparse forest coverage means open country dominates, favoring glassing and ridge hunting.

Over 350 miles of roads provide the backbone of access, primarily via WDFW roads (14, 10, 10.10) that penetrate from multiple directions. Colockum Road approaches from the north, river access exists at Vantage and Scammon Landing. The network is comprehensive enough that most of the unit sits within reasonable walking distance of driveable roads, reducing mystery terrain.

However, this same accessibility attracts predictable pressure, particularly along main drainages and known springs. Success requires hunting the margins—side draws, ridges, and areas between popular access points—rather than following the obvious routes.

Quilomene anchors to the Columbia River as its primary boundary, stretching from Tarpiscan Creek east to the Grant-Kittitas county line near Vantage, with I-90 forming the southern border. The unit sits in the transition between the gorge's steep cliffs—notably Cape Horn's dramatic escarpment—and the rolling shrubsteppe inland. Colockum Pass marks the northern approach via Colockum Road, establishing a natural gateway.

This positioning puts the unit within day-trip range of Ellensburg and the Tri-Cities corridor, making access straightforward but predictable.

The Columbia River provides a constant boundary, though its accessibility varies. Quilomene Creek, Perkins Fork, and Brushy Creek drain the interior and hold reliable water year-round in their lower reaches. A string of named springs—Reynolds, Government, Buckhorn, Collins, and others—dot the mid-elevation zones and create natural water stations that concentrate game.

Tekison Creek enters from the east. Water abundance means less stress on locating game around limited sources; instead, hunters should focus on how water corridors intersect with feeding areas and cover. Seasonal flows vary on smaller creeks; springs remain more dependable.

Black bear and mountain lion both inhabit the unit across its elevation range. Bears use the riparian willow corridors and rocky breaks year-round, moving to mid-elevation berries and acorns in late summer and fall; spring hunting targets emerging bears in drainages. Lions follow deer and elk movements through the sagebrush and scattered timber, preferring the creek bottoms and transition zones where cover meets open feed.

The rolling terrain rewards high-point glassing early and late—scan ridges and open slopes for movement, then work water sources during midday. The moderate complexity means the country isn't vast enough to get lost, but it's big enough to hold animals away from obvious parking areas if you're willing to climb ridges and work the flanks.
