Hey!!! So interesting, I thought I had made a post about this place but cannot find it. Then I went down the monkey hole of other notable places in the US. The mound builders are pretty prominent in the eastern states.
The thing the guy was saying about the strait line to Stonehenge, urm, yea? of course a strait line will intersect with anything
Maybe Xiao is close enough she can go give this place a rundown.
I'm also wondering if they have this carbon dating now how come the antiquities crew hasn't declared the place a monument?
