Have you heard of the Great Flood in 1862 in the US? It was the largest flood in the recorded history of Oregon, Nevada, and California. The flooding lasted months. This is thought to be a cyclical event and it would be interesting to know what you can find, cause some say it may happen very soon.
KD, since I can't write any posts, I was wondering how can I send you some interesting info (5 Pages) on which I'd love your input and even more if you made a more detailed post with your amazing research :D. Do I post it here? Or I send it to some email? Or what?
