The Active Volcano in Washington; Glacier Peak

There is only one volcano in the state of Washington other than Mt. St. Helens which is capable of and has produced multiple eruptions similar in size to Helens's infamous 1980 eruption during the last 20,000 years. The volcano I am referring to is still technically active, having last erupted a mere 300 years ago. This volcano is known as Glacier Peak, which could pose significant hazards to up to approximately 70,000 people if it was to ever erupt again.
