Sloan Peak is a 7,835-foot mountain in Washington’s North Cascades, between the forks of the Sauk River in the Mount Baker–Snoqualmie National Forest. Known for its sharp, isolated shape and dramatic relief, it is often called the Matterhorn of the Cascades and rises more than a vertical mile above nearby valleys on some sides. Its standard climbing line, the Corkscrew Route on the South Face and Upper West Face, combines glacier travel and class 3 rock scrambling. Harry Bedal and Nels Skaar made the first recorded ascent on July 30, 1921. The peak also reflects the region’s marine climate and glacially sculpted geology.
