interesting. They wonder how those raw materials, or perhaps finished pieces, made it to Ohio. They were simply traded from one group to the next.
Just like the diseases that they had no immunity for spread across the country.
I'm sure every group knew the others around them and traded.
I remember reading an account of a burial mound dug in the late 1800's in Ohio, and they found some brass rings with Chinese figures on them. Now THAT makes me wonder how those got there.
