Carbondale, Illinois is in the path of this eclipse, as well as the eclipse coming in seven years. The Ark of the Covenant must be there.
The collection of Indian mounds known as Cahokia is not far from there, about a 100 miles north, across from St. Louis. It has the largest Pre-Colombian earthen structure (Monks Mound) north of Mexico. I climbed it once, you get a nice view of St. Louis from the top, though it looks like a landfill. It is also said to be more populated 1000 years ago than London was at that time, 10,000-20,000 people.
Archaeologist are still trying to figure out what attracted so many people to that place.
