The Great Lakes were formed about 14,000 years ago, well within the time that humans were around. It would be cool if these drones were to spot some evidence of human occupation around this and other submerged mountains before they became submerged. I’m thinking at least petroglyphs or the remains of stone structures.
That would all have been scraped away by the glaciers.
Underwater Native American sites in the Great Lakes region include significant prehistoric hunting structures discovered beneath Lake Huron and Lake Michigan, dating back approximately 9,000 to 10,000 years.
