Jack Mountain/Nohokomeen Headwall

An early-spring snow climb of a prominent peak in the North Cascades. The Nohokomeen Headwall rises steeply above the Nohokomeen Glacier on Jack Mountain's northwest flank. Ascending the headwall involves climbing 700 vertical feet of snow at slopes up to 60°.


Drive SR-20, the North Cascades Highway, to the East Bank Trailhead (1,800 ft), near Milepost 138. Note that the western winter closure gate is at Milepost 134 (or possibly earlier), so climbing before the spring highway opening adds some extra miles.


Follow the East Bank Trail ~8 miles to the May Creek Campground. Head off trail and up ~3 miles to the toe of the Nohokomeen Glacier. Some of the route is steep and brushy. Either camp there or continue to the base of the headwall, camping anywhere along the way.


Pick a line and ascend the headwall, which gets quite steep near the top. Later in the season the bergschrund may be an obstacle. Depending on the snow conditions, a rope and protection may be needed. Gain the ridge and traverse over to the summit, taking care to avoid cornices.


Descend the climbing route.


Crampons and two tools. Rope and pickets. Snowshoes, depending on snow conditions.
