Overview

GMU 450 (Cascade) is a large, high-elevation North Cascades unit straddling the Snohomish/Skagit county line, split between WDFW Districts 13 and 14. The bulk of it is Mt. Baker-Snoqualmie National Forest and designated wilderness reaching toward the crest. This is scenic backcountry deer hunting, not a numbers unit — in 2024 only 73 hunters reported here and just two blacktail deer were taken. The draw is remote alpine country, a fall black bear opportunity, and a limited cougar hunt; the unit is closed to elk hunting because so few animals are present.

Terrain

Deep, steep, glacier-carved North Cascades terrain rising from the Sauk and Skagit valleys to jagged summits. The Mountain Loop Highway threads the western foot of the range between Granite Falls and Darrington, giving way to trail-only high country and wilderness to the east.

Cover: Dense westside conifer — Douglas-fir, western hemlock and western redcedar in the valleys and mid-slopes, grading into silver fir, mountain hemlock and subalpine parkland near timberline. Old-growth stands persist on Forest Service ground; regenerating cuts and avalanche chutes provide the best browse.

Landmarks: Mountain Loop Highway · Boulder River Wilderness · Glacier Peak Wilderness (eastern edge) · Sloan Peak · Whitehorse Mountain · Three Fingers · Mount Pugh · Sauk River · Skagit River

Access

Overwhelmingly public but rugged. Two Mt. Baker-Snoqualmie ranger districts cover the unit — Darrington RD (north) and Skykomish RD (south) — and both note many forest roads have been decommissioned or go unmaintained, so check road and gate status before you go. WDNR Northwest Region lands are common lower down and are frequently gated (Discover Pass required). Private industrial timberland formerly owned by Weyerhaeuser in this area was sold to Hampton Lumber in 2021; consult Hampton's access rules, follow all No Parking signs, and never block or drive past a gate that may lock during active logging. WDFW frames GMU 450 as scenic but thick, rugged and steep, with heavy hiker/recreation traffic on fair-weather days.

Species notes

Blacktail Deer

limited opportunity

Columbian black-tailed deer are present but at low density and lightly hunted; harvest is minimal (two deer from 73 hunters in 2024). This is DIY backcountry deer hunting where scouting to find where deer concentrate — and getting away from crowds — matters more than the tag.

  • Glass regenerating clearcuts, avalanche chutes and burn/brush edges for browse
  • Hunt the transition between old-growth cover and open subalpine parks at first and last light
  • Push farther and higher from the Mountain Loop trailheads than day-hikers go
  • Be realistic — plan a hard backcountry effort, not a road hunt

Black Bear

common opportunity

Black bear are the most reliable big-game opportunity here, feeding in berry fields, avalanche tracks and regenerating cuts through late summer and fall. In 2024, 89 hunters reported here with a 32% success rate the prior season — strong for a westside mountain unit.

  • Scout and monitor huckleberry/berry patches, then hunt them cool mornings and evenings
  • Glass open avalanche chutes and old cut edges from a distance
  • Bears are lower in riparian areas early, then move higher as the season progresses
  • Successful hunters must submit a premolar tooth to WDFW

Mountain Goat

limited trophy

Mountain goats occupy the high crags of the unit (the Boulder River North goat area lies within the Mt. Baker-Snoqualmie NF here), but declining population estimates have suspended goat permits for the 2025 season. Historically a rare, once-in-a-lifetime draw with very high permit success.

  • This is a permit-only, draw-dependent hunt — verify current WDFW goat season status before planning
  • Goat numbers here are being actively monitored after poor survival of translocated animals from Olympic NP
  • If ever reopened, expect technical alpine terrain and a serious pack-out

Cougar

common opportunity

GMU 450 is a managed cougar hunt area with a small annual harvest cap; cougars follow the deer through the timbered valleys and lower slopes.

  • Call the WDFW cougar hunting hotline to confirm the unit is still open before hunting — the harvest guideline closes it fast
  • Fresh snow makes tracking the most productive method in late season
  • Focus on deer wintering cover in the lower drainages

Pro tips

  • Treat 450 as a scenery-and-solitude backcountry hunt — the payoff is wild country and a fall bear, not a big deer harvest
  • Bear is the best-odds big game here; find and monitor berry fields and avalanche chutes and hunt them at the edges of the day
  • Check MBS road and gate status with the Darrington and Skykomish ranger districts before every trip — many roads are decommissioned
  • Expect heavy hiker and recreation traffic on fair-weather weekends; hunt weekdays and smaller basins off the main trails
  • On the private timber portions (Hampton Lumber), never block gates and heed No Parking signs — vehicles get towed

Watch out for

  • !GMU 450 is closed to elk hunting — only scattered individuals use the high country in summer
  • !Steep, thick, rugged terrain with real backcountry hazards; decommissioned and washed-out forest roads limit access
  • !Mountain goat permits are suspended for 2025 due to population declines — do not plan a goat hunt without confirming season status
  • !Cougar hunt is capped — the unit can close mid-season once the harvest guideline is met; call the hotline first
  • !North Cascades weather turns fast; early snow can strand hunters on upper roads

Logistics

Darrington (north) and Granite Falls (south) anchor the Mountain Loop Highway corridor and provide the last reliable fuel, groceries and lodging; Concrete and Marblemount serve the Skagit/SR-20 side. Dispersed and developed camping is available throughout the Mt. Baker-Snoqualmie NF. Cell coverage disappears quickly off the main corridors — carry a paper forest map and check road status with the Darrington or Skykomish ranger districts before heading in.
