MOUNT ST. HELENS

When Mount St. Helens erupted 25 years ago on May 18, 1980, 230 square miles of forest were blown over or left dead and standing. Despite the devastation, an outstanding scientific opportunity was created. Scientists from throughout the world came to observe geologic and biological processes first hand and, in 1982, Congress established the 110,000-acre Mount St. Helens National Volcanic Monument (NVM0), where the environment is left to respond naturally to the disturbance. We'll look at the first twenty-five years of recovery, the opening chapter in a long-term (200- to 500-year) sequence that will eventually lead from ash-covered blast zone to old-growth forest.
