Yes, the copper comes from Michigan, but can be found along prehistoric trade routes that extend all the way to Charleston, SC, and down to beyond Valdosta, GA during this time frame. Also, ceramics from the Savannah River area can be found up near Michigan. The same exact people lived in at least two sites on the far opposite ends of that trade route, with more found every year....They got around...
Amazing. I knew that certain types of stone which were prized for making tools were dispersed by trade over wide areas. Shells from coastal areas ended up far inland also
