Mount St. Helens was once a beautiful, symmetrical example of a stratovolcano in the Cascades mountain range in southwestern Washington, rising to 9,600 feet (3,000 meters) above sea level. Then, on May 18, 1980, the once-quiet volcano erupted and blasted off the upper 1,000 feet (300 m) of the summit. A horseshoe-shaped crater and a barren wasteland were all that remained.
