The Full Story

Mount St. Helens is located in southwestern Washington, in the Cascade volcanic arc of the United States. Its dramatic 1980 eruption blew off the north flank of the mountain, triggered a huge landslide, and sent an ash cloud across much of North America. The eruption also formed a horseshoe-shaped crater and transformed the landscape around it. Today it remains an active volcano and a classic example of explosive stratovolcanic behavior.
