Mt. St. Helens

The eruption of Mt. St. Helens in Washington State in May 1980 resulted in a variety of projects at Pacific Northwest National Laboratory. The work included sampling and analysis of the ash, biological effects studies, and public information programs. This shot was taken from our research aircraft as it collected atmospheric samples near the crater.
