Sounds like an interesting project up in NE MO. Maybe they will find the match to my chert Atlantean mapstone found in the St. Louis area. It resembles in style and form the map published by Athanasius Kircher in 1665. He used ancient Egyptian sources for his map. Interesting enough, I found Egyptian material, too. It's all there awaiting discovery -- we just need to oust the mainstream history cops of the world, and get busy telling the REAL history of this land!

Cheers
