The Force is Strong With This One
Apparently ancient miners extracted up to 1.5 billion pounds of copper from several mines in Michigan, USA
Have the Cs mentioned or alluded to these mines and what possible use the copper had ?
Curious how such a site being 5000 years old has managed to slip past the American archaeologists once again.
After all that is a massive amount of copper by today's standards, truly industrial operation.
