Where did this meteor hit at? I’ve never heard of a meteor striking that area before 13k years ago.
Check out the book in comment #2. If you Google the title, you probably will get a good summary from Amazon or one of the companies that sells used books.
I bought and read the book. One or more boloids struck the Northern Hemisphere between 13 and 14,000 years ago. This started the long chill called the Younger Dryas. Probably formed Lake Michigan, Carolina Bays, etc. Also killed off most major fauna and Clovis people leading to extinctions. The arguments for these facts/ideas are well detailed.
