The West Ridge of Prusik Peak is rated Grade II, 5.7.

getting there

Drive US-2 over Stevens Pass to just west of Leavenworth. Turn right on Icicle Creek road and drive 8.6 mi to Eightmile Road. Turn left and drive 3.5 mi to end and the Stuart Lake Trail, 3,600 ft.

APPROACH

Hike trail about 2.5 mi to Colchuck Lake Trail 1559A. Follow the trail across Mountaineer Creek, then south through boulders and up switchbacks 1.6 mi to Colchuck Lake, 5,570 ft.

To ascend Aasgard Pass (labeled Colchuck Pass on USGS Enchantment Lakes map), follow the path around the lake to the large boulders at the south end of the lake. Follow the stream staying to the left and eventually going left of the first cliffs. Continue southeast up rock and heather, or snow in early season, to just northeast of Aasgard Pass and upper limit of the Enchantment basin.

Descend easterly through the lake system of the upper plateau. When the route drops from Talisman Lake to Rune Lake (Inspiration and Perfection, respectively, on USGS Enchantment Lakes map) ascend to Prusik Pass and up the West Ridge until it steepens.

ASCENT ROUTE

Two pitches of class 4 and low class 5 lead to the crest of the West Ridge. The third pitch begins with a short unprotected 5.7 friction slab followed by easier climbing. Traverse on the south side of a prominent horn to a belay on the ridge. Traverse left, class 4, via ledges on the north side until under the summit. From the highest easy ledge lie back up a steep corner, 5.6, for about 10 ft or jam and mantle onto ledge that leads out and right. Climb a right facing thin flake to another ledge. A short narrow chimney leads to the summit.

DESCENT ROUTE

Descend off the north face with three to four single rope rappels or various combinations of double and single rope rappels. When able traverse left, west, to Prusik Pass at the base of the West Ridge.
