The Cycle of Cosmic Catastrophes:
Flood, Fire, and Famine
in the History of Civilization
by Richard Firestone,
Allen West, and
Simon Warwick-Smith
Great book. I really think this is a very valid hypothesis for the formation of the Caroline Bays, the death of the megafauna, and the end of the Clovis culture. Although this book proposes a highly involved cause for all these effects, they go into considerable well written detail about the scientific effort to verify their hypothesis. Highly recommment it.
Incidentally, is the few paragraphs posted the whole article, or was a link to rest of it not posted?
