Images taken from reference below

Mount St. Helens' perfect cone used to be seen as the United States' own Mount Fuji. This all changed on May 18, 1980 when the top 1400 meters was shot away by a cataclysmic eruption. Hot gasses and magma that travelled ahead of the debris avalanche flattened and area of 600 square kilometres. Mount St Helens is the most active volcano of the Cascade Range(part of the Western Cordillera). It is a stratovolcano, typical for being above a subduction zone.
