Hi Chief Infidel,
I'm happy to promote this to
Geology and the Great Flood as is, if you like, but I should probably point out to you that you're going to encounter objections to your understanding of the Flood, one being that there were no very high mountains like Everest at the time, and another being that all the water didn't come from the rain but from something called "the fountains of the deep." So you might want to review some other threads on the ark first, and maybe rewrite your calculations in the OP.
Let me know when you're ready by posting a reply to this.
