Mount St. Helens in western Washington State is a stratovolcano. It's last major eruption occurred on May 18, 1980 after laying dormant for 10,000 years. It is the most active volcano in the Cascade Mountain Range. This image was captured one week after the March 8, 2005 ash and steam eruption. A new lava dome in the southeast part of the crater is clearly visible, highlighted by red areas where ASTER's infrared channels detected hot spots from incandescent lava. The new lava dome is 155 meters (500 feet) higher than the old lava dome, and still growing.
