Geology

The Geological History of the Lake Superior region began nearly 3 billion years ago with the building of a continent, it is still active today as the Earth changes and reforms itself through geologic time. Navigate from The Lake Superior Basin: A Story Told in Ancient Rocks through Glacial Lakes History & The Development of Lake Superior as we tell the story of our Lake Superior Region extending from ancient Precambrian (pre-advanced life times) to the present day.
