Jack Mountain

Jack Mountain stands as the highest non-volcanic peak in the North Cascades, and the Nohokomeen Glacier headwall route attacks it from the north via Ross Lake. The approach by boat across Ross Lake to May Creek sets the tone: this is deep wilderness skiing accessed through a landscape most people only see from a car window on Highway 20.

From May Creek, the route follows the East Bank Trail for two miles south before turning directly uphill through dense forest. The bushwhack gains roughly 4,500 feet from lakeshore to summit, transitioning from old-growth timber to open alpine slopes on the glacier. Camp goes in at the glacier's base for a two-night stay, allowing a summit day with lighter packs and the option for sunset ski laps on the lower glacier.

The Nohokomeen Glacier headwall is the crux. Steep enough to require crampons and ice axe on the ascent, it delivers a long, sustained descent through powder or corn depending on timing and aspect. The north-facing headwall holds cold snow well into May, while the lower glacier transitions to fast corn by mid-morning. From the summit, the panorama takes in the entire Picket Range, Mount Shuksan, Mount Baker, and the length of Ross Lake below.

This route sees very few parties. Limited beta exists compared to more popular North Cascades ski objectives, and the boat shuttle logistics add a layer of planning that keeps traffic low. Solid glacier travel skills, comfort on steep firm snow, and self-sufficiency in remote terrain are baseline requirements.
