GMU 388 - Grayback, Washington

GMU 388 spans roughly 487–494 square miles (311,000–316,000 acres) across western Klickitat County and the southern tip of Yakima County. Elevation ranges from ~160 ft at Lyle (where the Klickitat River meets the Columbia) up to 5,820 ft at Indian Rock on the northern border. The northern third of the unit holds ponderosa pine and mixed conifer timber, transitioning at roughly 2,000 ft into open arid scabland of sage, buckbrush, native bunchgrass, and dry-land farming (grass hay and grain). Gunn Butte (2,215 ft) is a prominent landmark in the mid-unit. Terrain slope: approximately 80% of the unit has slopes of 25 degrees or less, with steeper canyon terrain along the Klickitat River drainage.

Approximately 10–11% public land. Land ownership breakdown: ~1% USFS, ~8–9% Washington State (DNR/Wildlife Area), ~1% NPS, remainder (~89–90%) private. The Klickitat Wildlife Area Soda Springs Unit (~13,000 acres) is the largest contiguous public block and the primary hunting destination for non-landowners; camping is permitted at Soda Springs but a campfire ban runs June 1–October 30. Dillacort Canyon, while landlocked by private, is accessible via the Klickitat River corridor. No National Forest land of consequence within the unit. Road access is primarily via US-97 north from Goldendale and SR-142 along the Klickitat River. Private timber-company access permits can significantly expand opportunity.

Northern third: ponderosa pine, Douglas-fir, mixed shrub-steppe transition. Mid-unit: open scabland with sagebrush, bitterbrush, buckbrush, bunchgrasses. Southern tier (Columbia River breaks): steep basalt canyon walls, rabbitbrush, sparse juniper, riparian cottonwood along the Klickitat River. Dry-land grain and hay fields on private land provide important deer foraging habitat and concentrate animals in early season.

Mule deer are widely distributed but strongly avoid high-human-contact areas; early season animals concentrate in timbered northern portions and move to lower elevations and open breaks as temperatures drop and snow pushes them down. Elk herds are small and highly nomadic — easily displaced by hunting pressure — with the best elk habitat in the northwest corner of the unit. Elk rut activity typically begins the first week of September and runs approximately one month. Mountain lions are present and are considered a limiting factor on deer populations in portions of the unit.

Unit converted from blacktail to mule deer classification in recent management cycles. Deer populations have shown recovery trends; District 9 (which encompasses GMU 388) carries an estimated 20–25% deer hunter success rate. The Soda Springs Unit experiences heavy pressure on opening weekend — arriving Thursday or Friday to scout and stake a position is advisable. Private land permission is the single biggest success multiplier in this unit. The Simcoe Mountains Wildlife Area is located in neighboring GMU 382 (East Klickitat), not 388 — hunters researching Simcoe should apply for Deer Area 5382 special permits. Black bear and turkey are also available on general licenses. No significant special draw elk permits reported for this unit; all current elk seasons are OTC spike-only.
