Mount Mystery, mountain in Washington, United States of America

Mount Mystery is a summit in the Olympic Mountains that rises to about 7,600 feet and features steep rock faces and ridges. A smaller glacier sits on the eastern side, creating a landscape of stone and ice.

A Forest Service worker named G.A. Whitehead named the mountain in 1915 after spotting it through thick fog. The name reflects the mysterious appearance it had at the moment of discovery.

The name was given around 1915 by G.A. Whitehead of the U.S. Forest Service, who admired the peak's regal look in foggy weather. Deception Creek, a tributary of the Dosewallips River, drains its east and west slopes, and the small ice patch on the east side is called Mystery Glacier. The mountain is best seen from Puget Sound lowlands.

The climb requires advanced skills and solid equipment since the mountain is remote and weather can change quickly. Visitors should start early and be prepared for conditions to shift during the day.

Little Mystery, a 6,941-foot subsidiary summit, lies just south of Mount Mystery. The main peak is the sixth-highest in the Olympic Mountains, after Mount Olympus, Mount Deception, Mount Constance, Mount Johnson and Inner Constance.
