On May 18, 1980, Mount St. Helens erupted, blowing 1,300 feet off the mountain and killing 57 people.
In a 2005 Willamette Week retrospective, Patty Wentz wrote about the significance of the event.
The explosion, which shot ash 80,000 feet in the air, was so major, it could be seen in space.
Today, one of the least-appreciated government agencies, the National Environmental Satellite Data and Information Service (NESIDS), released video showing what the eruption looked like from space.
