On Mount St. Helens, a volcanic formation seems to come to life as it exhales a cloud of steam. The volcano in southwestern Washington's Cascade Range is most famous for its May 1980 eruption, one of the largest ever recorded in North America. The catastrophic eruption killed 57 people and triggered an enormous debris avalanche that carved a mile-wide (1.5-kilometer-wide) crater on the mountain.
