I believe that the most significant fact concerning these obsidian artifacts is that their original source was on the West Coast, in Oregon and was found in the Great Lakes.
Lithic artifacts moved considerable distances during the Paleoindian era, but mostly from the East toward the West, with many of them ending up in caches that were never recovered in antiquity. This tells us that ancient people in the Great Lakes traded with people from the West Coast, or that there was a trading network that connected these people to exchange this obsidian.
or Noah’s flood had a current
Nope.
The most significant fact is that the water level rose that much with no burning of fossil fuels and no SUVs.
Now, that’s a supply chain!
It’s not like any single person is likely to have carried obsidian all the way to Lake Huron from Oregon, but like today, they probably had raw material suppliers, distributor, manufacturer, and retail, trading the whole way.
Just like a modern free market economy.
