Exactly. In the last iceage sea level was over 2000 feet lower
Closer to 400’ lower.
-In the last iceage sea level was over 2000 feet lower-
Two thousand feet lower? That doesn’t seem possible so I ask GROK.
No, sea levels during the Last Glacial Maximum (LGM, ~26,500–19,000 years ago, the peak of the last Ice Age) were not over 2,000 feet lower than today. They were approximately 400–430 feet (120–130 meters) lower.
The water for a mile of ice over Chicago had to come from *somewhere*!
