It’s amazing how little people understand about our recent geologic history. For instance, most don’t realize that during the period you highlight, what is now known as Chicago was under a MILE of ice. The Great Lakes didn’t exist 25K-years ago. Instead, they were created when the ice from the last ice age retreated.
Think about how much colder it had to have been for a mile of ice to accumulate over most of what is now the Midwest. Our climate has changed significantly in what has been a blink of an eye, geologically...and it all had nothing to do with Mastedons and their SUVs.
“It’s amazing how little people understand about our recent geologic history.”
How can the little people understand this better than the big people? Maybe there is something wrong with your historical records.
