Today is May 18 and that marks the date of the 1980 eruption of Mount St. Helens in Washington that killed 57 people (video). I don't have an elaborate post on the event - so if you want to find out more about this historic eruption, be sure to check out the excellent USGS site on the event. Or, you can relive (or just "live") the events of May 18th through the memories of Eruptions readers - you all submitted two posts worth of St. Helens memories last year for the 30th anniversary.

Some fun new St. Helens-related items to examine:
