The Curious Case of Phineas Gage.
For the uninitiated, Ol' Phineas had a 3'8" long, 1.25" wide tamping iron shoot through his head and lived to tell.
Yeah, that's the iron right next to his skull in the picture above.
Swing over to PUFF (the AVO's very cool and very informative volcanic ash tracking model)to check out plume and ash predictions in colored animation--it's like watching a map of AK puke rainbows all over itself.
