Mount Hood 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 miles (80 km) east-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. With a summit elevation of 11,249 feet (3,429 m), it is the highest mountain in the U.S. state of Oregon and is the fourth highest in the Cascade Range. Ski areas on the mountain include Timberline Lodge ski area, which offers the only year-round lift-served skiing in North America, Mount Hood Meadows, Mount Hood Skibowl, Summit Ski Area, and Cooper Spur ski area. Mt. Hood attracts an estimated 10,000 climbers a year.

The peak is home to 12 named glaciers and snowfields. Mount Hood is considered the Oregon volcano most likely to erupt. The odds of an eruption in the next 30 years are estimated at between 3 and 7%, so the U.S. Geological Survey (USGS) characterizes it as "potentially active", but the mountain is informally considered dormant.
