Photo: Aerial View Of Islands Lake Superior Thunder Bay Ontario

The water is so clear and blue that when taking a flight from Thunder Bay over the small islands in Lake Superior that you can see right through to the rocks underneath the islands - it is a stunning aerial view.

Lake Superior, the largest of all the Great Lakes, is also the largest freshwater lake in the world in terms of surface area, and the third-largest due to volume. It is also the deepest and coldest of the Great Lakes. There are a number of islands in Lake Superior, one of which can be seen in this aerial view.

The largest island in the lake is Isle Royale in Michigan, but some of the other well-known ones include Madeline Island and the Apostle Islands. Some of the rocks in and around Lake Superior are some of the oldest in the world. There has been quite a bit of movement under the bed of the lake, as it sits on part of the Canadian Shield, therefore there have been a number of rock formations that have sprung up over the many years this lake has been in existence. ... continue below the picture...

An example of this movement around the lake was the Wisconsin glaciation that happened about 10,000 years ago. Ice covered the entire lake and as the ice retreated it left all the contours and ridges that exist today. Rocks would have moved and formed during shifting, and some of that evidence can be seen below the surface of the water. Due to a lack of pollution and contamination so far, the water is still clear enough to see below the surface of the water to the base of the islands where from an aerial perspective one can see the shelves of the rock.
