On October 1, 2004, an explosion in the crater of Mount St. Helens sent ash and water vapor several thousand feet into the air. It was the dramatic beginning of an eruption that continued for the next 3+ years. The explosion fractured Crater Glacier and hurled rocks for at least one-half mile across the western half of the glacier and the 1980-1986 lava dome. USGS scientists on a helicopter flight captured the explosion on video. The view from the air is to the west.
