Great Lakes - Meteor Divots? (9 replies)

Hi All,

I read Graham's America Before and listened to 2 of his interviews on Joe Rogan and haven't found any references to this question. I grew up in Minnesota and have spent time near Lake Superior and Lake Michigan a good part of my life. As I have read about meteor impacts I was wondering with the amount of taconite and iron around the midwest if any research had been done on if Lake Superior, Lake Michigan, and Lake Huron could be the result of a large scale impact?

If the Younger Dryas meteor strike window was coming from a norther angle of decent and a larger meteorite broke apart as it got close to the earth could it have created these 3 lakes? The symmetry of the Lake Michigan and Lake Huron make me wonder if a meteor split apart down the middle and then its spin as hit create the curves in the 2 lakes. Lake Superior may or may not have been from the same parent meteor but simply went into the earth.

I found an article published in 1990 on research about researching the impact of meteors around the Great Lakes, but nothing else or no outcome of that research. Just curious, does anyone else have anything on this topic?

Thanks in advance.
