8. A few years ago I was helping a grandkid of ours with a report
about the Great Lakes. We came across a website with a very interesting report on Great lakes water level in historical context. For example....

Imagine you are a SCUBA diver exploring the bottom of southern Lake Huron. In the gloomy light
near the bottom, you see what appears to be a log, some branches, and other wood debris. You take little notice of these until you see a stump, with some obvious roots penetrating into the bottom. This seems impossible since it suggests this tree once grew here, a few miles offshore in 40 ft of water.
Although the logs and branches could have floated out from shore and sunk once they became
waterlogged, the stump could have grown in this position only if this area was once dry land.
Scenes like this are found in several areas of the Great Lakes. They represent undeniable evidence that water levels in the Great Lakes were once radically lower than they are today, making some of our concerns about recent low water levels pale in comparison. Imagine 300 feet lower!

It's really a fascinating study. Needless to say I, I mean, She got an A on the report
