Sloan Peak, Mountain summit in Snohomish County, Washington, US

Sloan Peak rises to 7,835 feet (2,387 m) in the North Cascades region and sits between the north and south forks of the Sauk River. The area is part of Mount Baker-Snoqualmie National Forest and features glacier fields and rocky slopes.

The first recorded ascent occurred on July 30, 1921, when Harry Bedal and Nels Skaar reached the summit. They established the climbing route that mountaineers have since followed.

Sloan Peak is nicknamed the "Matterhorn of the Cascades" for its sharp summit, made more striking by its isolation west of the Cascade crest. On the east and southwest sides the summit rises over 1,600 m above the valley floor in less than 3.2 km horizontally, so the peak is visible from many places in the North Cascades.

The main route crosses Sloan Glacier and requires glacier climbing and rock scrambling with roughly 5,935 feet (1,809 m) of elevation gain. Climbers should have experience with ice and rock techniques and be prepared for changing mountain conditions.

Sloan Peak's summit stands more than a vertical mile above the valley floor on both its east and southwest sides, achieved in under two horizontal miles. This relief, plus its isolated position west of the Cascade crest, is why it is called the "Matterhorn of the Cascades".
