[Black Agnes]

I wonder just how far inland that wave went. Wasn’t the shoreline vastly different then? I haven’t been able to find any really good answers to that one. Closest estimate I can find is something like 150km inland. Staggering if true.

That I simply don't know. 150 km sounds like a reasonable guess for flat shorelines near the strike. The crater is about 120 km in diameter today, and all the water it displaced had to go somehwere.

And that wasn't the worst of it...
