Now I wonder if maybe The Sea People had an advanced civilization living in the far north, or maybe in Doggerland / Atlantis, and they were sending ships across the Atlantic and through the Great Lakes to get this copper. That sounds kind of nuts, but if it wasn't The Sea People, then where did all the copper go?

I posted about upper Michigan copper mines before.
