Wall Lake is about 10,000 years old.  Glaciers formed and moved through the Upper Midwest from Canada about 14,000 years ago, and finally retreated about 9,000 years ago.  It is hard to imagine that the ice over the upper midwest was 1 mile thick at that time.

​

As the glaciers moved the land was eroded, the melting glacial ice formed lakes.  Michigan’s natural lakes, from the Great Lakes to inland lakes like Wall Lake, formed when the glaciers advanced and then retreated back into Canada.  What a magnificent gift!

​

Today the Great Lakes contain 20% of the world’s drinking water.

The below images show how the glacial ice moved down from Canada in a southeasterly direction and then retreated back into Canada in a northeasterly direction
