I didn’t know the American indians used copper. Any idea which tribes and what it was for?
The native copper came from up around Lake Superior I believe and was exported down the Mississippi river. The use as I recall was mostly ornamental.
In Chaco Canyon New Mexico and other anacazi sites, copper bells originating in Mexico were found.
There was a workshop at Cahokia that worked copper. That was where I became aware of the fact
At the zenith, Cahokia was larger than London.
