Mount St. Helens Eruption (PHOTOS): National Geographic Marks Its 30th Anniversary

On May 18, 1980, Washington's Mount St. Helens erupted, sending a debris avalanche of more than 3 billion cubic yards into nearby Spirit Lake, wiping away virtually all evidence of human and animal life. Three decades later, the current issue of National Geographic magazine marks the anniversary of the deadliest volcanic event ever in the United States with a story of rebirth and renewal on the mountain. We've teamed with National Geographic to bring you stunning images from the 1980 eruption and today's reborn landscape. National Geographic's website shares an interactive map of the blast zone, an interview with the mag's Editor in Chief, and a gallery of additional images.
