I know what he meant, but was responding to what he actually said. Ice is water and the whole Great Lakes system was carved out by ice during the last Ice Age. There used to be a mile of ice above what is now found. Anybody not believing it, can stand on the top of Maine's mountains and see huge, huge boulders perched where they could only be placed by melting ice. 14,000 years ago, my own state was 900 miles wide as the sea level was 300 feet lower. The water was all tied up in the frozen poles. The warming then was not caused by the cave man burning fossil fuels.
There is one place on I-35 between lanes just south of Hiway 210 (Cloquet, MN) where the original bedrock is exposed. Have to be in the north bound lanes to see the exposed rock formation. You can see scratch marks across the rock from the glaciers.
