That's a great memory! :)
I saw the story about that geologist on the Discovery Channel. I'm thinking he's from the U of Nebraska. Anyway, it's a fascinating story.
Actually, there were two "mongo blasts" - the first one was by far the biggest one. The second one only destroyed about half of the original crater.
Exact dimensions of the first crater escape me - but it was measured in miles.
Very HUGH blast. Neighboring terra firma - and all life - got real SERIES about it. Especially after they ceased to exist.
It's a hot spot. And it's been on a build up since the last HUGH blow - that would be the second one.
Very, very SERIES - especially if you live within a - oh, say 1000 mile radius.

I didn't think you were that old - you hold up extremely well /sarcasm
