I didn't live anywhere near here in 1980, but my wife lived in Ritzville then, and I've heard the stories about the ash cloud, the cleanup, and how her younger brother went temporarily missing because he thought it was the rapture.

The Spokane Spokesman Review has tons of great coverage of the anniversary, including the awesome slideshow below.

UPDATE: Don't miss the Big Picture Blog's awesome collection of St. Helens images.
