Glacier Peak
North CascadesBest May–Jul
A multi-day spring ski mountaineering trip up Washington's most remote volcano, via the White Chuck approach.
About This Trail
Glacier Peak is the most remote volcano in the lower 48 — no road comes within ten miles of the summit. The standard ski mountaineering approach uses the White Chuck trailhead and works in over twelve miles to a high camp at Glacier Gap before pushing to the ten-thousand-five-hundred-foot summit via the Cool and Gerdine glaciers. The full trip runs three to four days minimum, with significant cumulative climbing across approach and summit days.
The summit day climbs through Disappointment Peak's south side onto the upper Cool Glacier and crosses to the Gerdine for the final summit pitch. Skiing back from the summit ridge can deliver a sixteen-hundred-foot continuous descent through forest glade if conditions cooperate. The standard glacier descent threads crevasse fields that vary year to year.
Spring is the only viable window. Memorial Day weekend trips have hit warm-night wet-snow cycles and widespread whumpf signals — pay attention to recent thaw cycles and current avalanche advisories. The exit involves alder bash at lower elevations as the snowline retreats. Northwest Forest Pass at the trailhead; wilderness permit self-issued for camps in Glacier Peak Wilderness.
Open glacier skiing on Cool and Gerdine. Forest glade descent from the upper ridges (~1,600 ft continuous in good conditions). Mix of corn and refrozen surfaces depending on cycle.
No established skin track most years. Multi-day trail-breaking from White Chuck through complex glacier terrain. Bootpack on the steepest summit pitches.

Scorecard
Few parties make the full trip in any season. Most weekends see fewer than a handful of ski parties on the mountain.
Safety & Considerations
Today's Hazard
- Strong sun — sunscreen, hat, and sunglasses recommended
Persistent Hazards
- Glacier travel on Cool and Gerdine — rope team and crevasse rescue gear mandatory
- Wet-loose avalanches and widespread whumpf signals after warm cycles
- Slab activity observed on Disappointment Peak south side under poor cycle
- Multi-day commitment with no easy bailouts — weather window mandatory
- Alder bash on lower exit as snowline retreats
- Wilderness permit self-issued at trailhead
