Alabama #3

Thanks to a careful reader of this blog a gigantic mistake was detected in yesterday's data.  I said  there had been humans in the United States for over 1000 years.  I meant to refer to when the Indians built mounds at Moundville.  Actually there have been humans here for at least from between 10 and 20 thousand years ago.

Here is an interesting site that talks more about these fascinating mound structures and has some pictures of the art created there.
