Mount Bachelor

Mount Bachelor is a dormant stratovolcano in Deschutes County, Oregon, rising to an elevation of 9,065 feet (2,763 meters). The summit displays a broad, rounded shape and the slopes consist of dark rock layers of volcanic origin.

The volcano formed between 18,000 and 8,000 years ago through several eruption phases. The last eruption took place around 5800 BC and left lava fields on the northern and western flanks.

The earlier name Bachelor Butte was changed in the 1950s to support the ski area's development. Today, locals know the peak by both its old and new names and use the surrounding forests for hiking and mountain biking in summer.

The access road Cascade Lakes Highway runs in summer to the parking area below the summit and provides trailheads for hikes. In winter, access is only through the ski runs and lifts, with upper areas often exposed to strong winds.

The summit crater measures roughly 300 feet (91 meters) across and is accessible to hikers in summer who complete the final section on foot. The upper lift terminal sits just a few hundred feet below the highest point and allows views across the Cascade Range.
