Re: Understanding the Topography of the Mississippi Embaymen
Interesting theory here and some nice discussion springing up. I took the time to look through the suggested evidence and went in very open minded.
I do have some questions about your main points of evidence for this impact crater.
Let's first look at your meteors you display on your site:

some good examples can be found here:
http://www.eserc.stonybrook.edu/terryville/Rocks/http://geogypsytraveler.com/2011/10/Which, as you see, can look much like meteorites, but are in fact formed by diagenetic processes. There's even reference to them in the Mississippi area on a geocaching website:

At a certain point the Tenessee river broke trough the natural barrier (in the red circle) and started flowing north-west. True, the river might have been flowing south before that (although I do not see the old river channel you talk about), but avulsions and breaking through geological barriers occur often and do not have to be related to any inpact or sudden shifts is topography. Erosion can cause this as well.
What do you think will happen when one of our dikes break here in Holland... our rivers will start flowing in a different direction.
Just my view on things and I am sorry I can not get on board with your hypothesis. Very interesting stuff though and maybe I am overlooking things...
Comments are very welcome!
