About Mount Saint Helens

Mount Saint Helens is a stratovolcano in Washington’s Cascade Range whose summit elevation is 2,539 m (8,330 ft) after the 1980 eruption removed its upper approximately 400 m and left a horseshoe-shaped crater partly occupied by a lava dome and glacier . The Smithsonian Global Volcanism Program classifies it as a composite stratovolcano and records an elevation of 2,549 m (8,363 ft), reflecting a differing reference measurement, with the latest known eruption listed as 2008 .
