If it gets repeated on TV, it's worth watching a programme that was on Horizon last night - I can't remember the exact name but the sub title was 'Ice age oasis' and was all about Florida as it was 13,000 years ago during the ice age. It was fascinating to see what the landscape was like and the animals that were around, including 1 that apparently has only been found in Florida called the Glyptadon (that's how it's pronounced, not sure on spelling). It's only close relative is the armadillo but it had a much thicker shell and was much larger.
The land was much wider due to the large masses of ice further north causing the sea level to drop and meaning much more of the coast line was actually exposed, they have found this because of tree roots growing under the river and sea beds.
It was a really interesting programme, and certainly worth looking at if it comes around again as I know they often do.
