On the morning of May 18, 1980, an earthquake shook Mt. St. Helens and the mountain's north face collapsed in one of the largest debris avalanches ever recorded. The mountain wrecked havoc killing 57 people and thousands of animals, took out 250 homes, 47 bridges and 185 miles of highway, clogged rivers, flooded valleys and blocked the Columbia River shipping channel.
41 years later, we can see the return of thousands of animals, trees growing back, and thriving ecosystems.
