The Indian-as-great-civilazation crowd is doing a lot of work in Stone Age American archeology in the Indian mounds: a lot is tinged (or hiding behind political correctness as their faults tend to be hidden, and successes amplified) but there is more work being done. I've been to the Illinois and Missouri Indian mounds, and the ones in north GA and Alabama.

Impressive, but they are not much more complex than piled up dirt.

Get enough people/slaves/prisoners, and you can pile a lot of dirt up. Strange that this mound didn’t start getting holes and subsiding marks in the top until the arch’s starting tunneling recently.

I don’t understand how they could tell this is a man made mound and not a natural hill? Anyone?

Also, maybe the point to be yet discovered here this ancient civilization’s people didn’t have much in the way of brain cells, lol. Spending a lot of time making a hill...?!
