Unit Umtanum

Cleman Mountain serves as a dominant ridge landmark for orientation and long-range glassing. Wenas Lake and Berglund Lake anchor water reference points, though both are relatively small. The canyon systems—Evans Canyon, Horse Trough Canyon, Hardy Canyon, and others—provide natural navigation corridors and drainage routes.

Ellensburg Pass and Lookout Point offer vantage positions for glassing adjacent terrain. Wenas Mammoth Mountain marks a secondary ridge feature. The Yakima River bend near Horseshoe Bend provides geographic anchoring.

These landmarks form a navigation grid across rolling terrain that would otherwise lack obvious visual breaks.

The unit spans lower elevations without extreme relief, rising from 1,053 feet in the river corridor to 5,194 feet on ridgetops. Most terrain sits in the 1,500 to 3,500-foot band—rolling sagebrush and grassland country with scattered ponderosa pine and Douglas-fir. The Yakima River corridor supports riparian vegetation and cottonwoods, while higher ridges transition to denser forest patches.

Sparse timber dominates; open grasslands, rocky outcrops, and brush-covered slopes comprise the bulk of huntable terrain. Cleman Mountain and the Wenas ridges mark elevation transitions where timber becomes more consistent, though coverage remains broken by clearings and rocky benches.

A well-developed road network totaling 538 miles provides connected access throughout the unit. DNR and Forest Service roads penetrate most drainages and reach ridges, enabling relatively easy vehicle access to staging areas. Population centers at Yakima, Ellensburg, and Naches provide nearby support.

However, the connected road system also means dispersed access points and moderate hunting pressure during season openers. Fewer hunters typically venture beyond immediate road corridors into the canyon systems, creating quieter terrain for those willing to glass and hike away from vehicle access. The rolling topography and scattered timber can quickly swallow pressure if hunters push beyond easy parking spots.

Umtanum occupies the transition zone between the Yakima River valley and the semi-arid ridges of central Washington. The unit anchors to the Yakima River on its southern boundary, with Interstate 82 and US Highway 12 forming the southern edge near Yakima. The northern boundary follows SR 410 and Forest Service Road 1701 along the crest of rolling terrain.

The eastern limit traces Umtanum Creek down to the Yakima, while the western side follows Wenas Road and creek drainages. The unit sits roughly 40 miles east of Seattle, making it accessible but distinct from the high Cascades to the west.

Water is limited but concentrated in specific drainages. Umtanum Creek, Wenas Creek, and North/South Fork Wenas Creek provide reliable flow during hunting season, especially early season. The Yakima River runs permanently through the southern boundary.

Scattered springs—Wright Spring, Willow Spring, Two Point Spring, Oasis Spring, Box Spring, and others—dot the ridges but are unreliable without local knowledge. Numerous ditches and canals (Gleed Ditch, Kelly Ditch, Wapatox Canal) serve agriculture and may provide supplemental water in certain areas. The unit's water scarcity directly impacts hunting strategy; animals concentrate in drainages where water persists, making creek-bottom movement predictable for hunters.

Umtanum supports black bear and mountain lion—species that use the drainage systems and forested ridges. Black bears concentrate on lower elevation drainages during spring and early summer, utilizing riparian zones and brush for food and cover. As season progresses, they shift upslope to higher ridges and canyon systems where mast and vegetation are available.

Mountain lions follow prey corridors along creeks and ridges, using scattered timber for ambush cover. Hunt strategy revolves around glassing the open ridge benches and sagebrush slopes early in the day, then working drainages and timber patches during midday. The canyon systems become productive travel corridors during late evening.

Water sources in Umtanum and Wenas creeks draw both species during drought periods, making creek-bottom stalks effective.
