Summary:Previous reports suggested that Glacier Peak, a volcano in northern Washington State, has been dormant for the past 11,000 years. New radiocarbon dates for volcanic deposits indicate that major volcanic events, such as tephra eruptions, pyroclastic flows, and mudflows traveling tens of kilometers, occurred at least five times in the past 1800 years and nine times in the past 5500 years.
