If you’re planning a Great Lakes beach vacation, here’s something to ponder. Your favorite beach wasn’t there 14,000 years ago.
But 14,000 years ago most of them were under ice and the lakes that existed weren’t in the same place. The western part of Lake Erie was under Lake Maumee. The toe of Lake Michigan was covered by Lake Chicago. As the ice receded the Great lakes took on their present shape.
A lot has changed in the last 14,000 years. Browse the maps below to find your beach at the ancient Great Lakes.
