Mount Shuksan ranks No. 96 among the Lower 48 Top 100 prominence peaks in the Prominence Registry, rising 9,130 feet in the Skagit Range of Washington with 4,405 feet of clean prominence. Unlike the volcanic cones that define much of the Cascades, Shuksan is built from Shuksan greenschist, metamorphosed oceanic basalt of the Easton terrane. Most climbers use the Sulphide Glacier route for roughly 16 miles round-trip with about 6,600 feet of gain on Class 4 terrain; an overnight backcountry permit is required within North Cascades National Park.
The mountain sits 10.35 miles from its line parent, Mount Baker, with deep surrounding valleys giving it the character of a major independent summit. The highest point is a three-sided pinnacle called the Summit Pyramid. The first recorded ascent was made by Asahel Curtis and W. Montelius Price on September 7, 1906, though a disputed earlier claim from 1897 exists. The name is commonly tied to Indigenous languages of the region; sources render it from Lummi or Nooksack forms meaning "high peak," "high foot," or "golden eagle."
Shuksan is frequently photographed from Picture Lake along the Mount Baker Highway, where the Sulphide Glacier, Summit Pyramid, and lower ice systems appear together. The climbing context differs from the view: Shuksan is a technical alpine climb from every standard approach.
