Tim looked up when these were most likely created and says they were created around 600-1540 a.d. We were able to look alot of them up but we can't find anything that tells us what that two-headed centipede looking one might be? Crazy!
They were made by the Anasazi, Incan, San Rafael Swell and other people's that have inhabited the area over past centuries. It was pretty neat to see considering how old they are.... !!! -
