Question about the Cahokia Mounds debate: were they a city or just ceremonial?
I was down in Collinsville, Illinois last spring checking out Monk's Mound and got into it with a professor who was saying the whole area was more like a seasonal gathering spot, not a permanent city. On the other hand, the visitor center there says it held 10,000 to 20,000 people at its peak with residential zones. Who's got the better evidence on this, the old school population estimates or the newer revisionist take?
