GMU 169 - Wenaha, Washington

Rugged Blue Mountains plateau dissected by steep draws and canyons carved by the Wenaha River and its tributaries. Elevations range from roughly 2,600 ft at Butte Creek bottomland to 6,368 ft at Mount Misery and Oregon Butte (6,329 ft) along the northern border. West Butte peaks at 6,263 ft, Twin Buttes at 5,656 ft. Topography is almost exclusively up-and-down — approximately 80% of slopes exceed 37 degrees — with zero roads inside the wilderness boundary. The 2015 Wenaha-Tucannon Wilderness fire burned roughly 83,000 acres across WA and OR (predominantly within the wilderness), creating a mosaic of low- to moderate-severity burn that benefits elk browse. A smaller 2021 fire burned a portion of the GMU as well.

100% public land; 95% lies within the Wenaha-Tucannon Wilderness administered by Umatilla National Forest. No motorized vehicle access inside the wilderness. Road-accessible trailheads on the perimeter include: Troy (Wenaha River Trail #3106, Crooked Creek Trail #3100), Diamond (Mt Misery Trail #3113, Melton Creek Trail #3124), Cross Canyon (#3242), Twin Buttes (East Butte Trail #3112, Grizzly Bear Trail #3103), and Tucannon (#3135). Entry points exist from both Washington and Oregon sides. Pack strings (mule or horse) are the preferred method for hauling gear into Wenaha Forks and deeper canyon country. The managed trail system totals over 200 miles. Access rating per WDFW District 3 Hunting Prospects (2025): Excellent.

Second-growth and old-growth forest dominated by ponderosa pine, Douglas fir, grand fir, and subalpine fir on north- and south-facing slopes, interspersed with native bunchgrasses, wildflowers, and forbs in open parks and benches. The 2015 fire created a mosaic burn pattern that opened canopy and boosted forb and shrub regeneration — prime elk and deer forage. Riparian corridors along the Wenaha River and major creeks provide thermal cover and year-round water. High-elevation benches in steep terrain serve as daytime bedding areas.

The Blue Mountains elk herd (estimated 4,262 animals in spring 2025) winters along the Grande Ronde, Wenaha, and Mill Creek drainages, with 500–600 animals sharing winter range with Oregon. Elk in GMU 169 have shown a persistent population decline over the past 35 years attributed primarily to high cougar predation on calves (cougars accounted for 75% of documented calf predation in the adjacent Oregon Wenaha WMA study), wolf pack activity (Wenaha, Walla Walla, and Shamrock packs occupy territories along the WA-OR border), and severe winters in 2016-17 and 2018-19. The 2015 and 2021 wildfires are expected to improve calf recruitment over time. Post-hunt bull:cow management target is 22–28 bulls per 100 cows; district-wide 2025 survey documented 26.1 bulls per 100 cows and a calf ratio of 19.3 calves per 100 cows — below long-term averages. Deer Areas 1008 and 1009 exist specifically to redistribute hunter pressure across the west and east wilderness corridor.

GMU 169 is managed as a core elk unit (alongside GMUs 154, 157, 162, 166, 172, 175, and 186) with a focus on population stability or growth. Branch-antlered bull harvest is by special permit only; general season is spike bull only. Elk Area 1008 (Wenaha West) and Elk Area 1009 (Wenaha East) divide the GMU to distribute hunting pressure — historically most permit holders concentrated near the western perimeter where road access was closest. Antlerless elk opportunity on public land has been eliminated across all core Blue Mountains GMUs due to low calf recruitment and post-2017 herd decline. Deer antlerless opportunity was also withdrawn for 2024–2026 to support white-tailed deer recovery following the 2021 hemorrhagic disease outbreak. CWD was confirmed in Eastern Washington as of 2025, adding new carcass/parts import rules. Chronic low elk densities in GMU 169 have persisted for 35+ years despite its large public footprint — hunters should set expectations accordingly and consider adjacent GMU 166 (Tucannon) or GMU 172 (Mountain View) for higher encounter rates. Pack animals strongly recommended for any serious hunting effort; this is Washington's premier backcountry wilderness elk hunt.
