1980 Mt. St. Helens Eruption Facts

Tens of billions of tons of ash...in a column 12 miles high.

Ash circling the globe in a few days. Twice.

Gas and pumice traveling at 300 miles an hour.

Buried groundwater superheated to form spontaneous guysers--some
creating craters a quarter of a mile wide.

Think about that.
