Eruption History

Glacier Peak (3214 m, 10544 ft) is a stratovolcano composed mainly of dacite, which is located about 100 km (65 mi) northeast of Seattle and 110 km (70 mi) south of the International Boundary with Canada. It lies in the rugged and scenic Glacier Peak Wilderness Area, in the Mt. Baker-Snoqualmie National Forest and rises only a few thousand feet above neighboring peaks that reach 2,700 m.
