Bob632, thanks for all of the links. I'm getting a stiff neck reading all of them.
I'm interested in your theories about some of the things you've posted. I've spent hundreds of hours looking for Old World influence here in the New World. Could you go into more detail about the use of the petroglyphs as boundary markers? For instance, have you found them used to mark huge areas or smaller plots? How about use along trading trails? And who used those trails?
