I’ll add you to the ping list, if nothing gets pinged in the next couple of days (really, in the next 8 hours), send me a private message as a reminder, or even do it now, I’ll see it right away when I’m back where I keep the list. :’)
I’d love it if the massive copper deposits of the far north of Michigan turned out to have been exploited by ancient “Old World” groups, but I don’t find that compelling. If there were an ancient wreck, that would be great; I’m not sure those currently wreck-mapping and such would notice something that anomalous. I could understand how the copper might have made it to the “Old World” via middlemen, that’s how it reached Central and South America.
Another obstacle is the waterway — there’s at least two places which would require portaging, or moving cargo from ship to carts, carts back to ships, again, middlemen.
I think reason the Phoenicians and Mycenaeans were credited with Stonehenge (for example) is that they were newly of interest perhaps 120 years ago, when there was a revival of interest in PreColumbian antiquities, while there was barely any study of or awareness of city-building by the ancestors of the locals. Now that the Mayan text is being read, there’s been an uptick in interest in Mayan stuff, and perhaps that’s why there’s a claim out there that the Mayans had colonized in at least one place in North America.
But this article dies mention the possibility of northern Europe having direct and massive contact with the wider bronze age world. That is still amazing to think about.
