Chapter 7 Current Issues: Mount St. Helens

 

Background

On the morning of May 18, 1980, Mount St. Helens erupted and destroyed more than 200 square miles of forest and spread ash across Washington State. According to scientists, 520 million tons of ash were blown east across the United States. The skies over many cities in the state were dark in the middle of the day. Fifty-seven humans and thousands of animals were killed.

During the more than 20 years since this major eruption, thousands of visitors have traveled to visitor sites near Mount St. Helens. During the last year, however, the mountain has again become active.
