The Active Volcano in Washington; Mount St Helens
Mount St Helens is the single most active volcano in the lower 48 U.S. states, being most infamous for its deadly 1980 eruption. While that eruption was indeed quite large, it was still smaller than 7 other explosive eruptions this volcano produced during the last 5,000 years. This video will discuss the Cascade Range's most likely volcano to erupt next, which is surprisingly only 40,000 years old and last erupted in 2008.
