Mount Hood, also known as Wy'east, is an active stratovolcano in the Cascade Range and is a member of the Cascade Volcanic Arc. It was formed by a subduction zone on the Pacific Coast and rests in the Pacific Northwest region of the United States. It is located about 50 mi east-southeast of Portland, on the border between Clackamas and Hood River counties, and forms part of the Mount Hood National Forest. Much of the mountain outside the ski areas is part of the Mount Hood Wilderness.
