Introduction
How The Region Was Formed
- 1400 years ago the entire Great Lakes lowlands were under a glacier that began to retreat at the end of the ice age.
- As the glacier retreated, it left indents in the ground that began to fill up with the water that was melting off the glacier.
- And as the glacier continued to retreat more and more indents were made and filled, which then the Great Lakes of today became more visible.
- The glacier had fully retreated and the indentations were completely filled, now it is recognizable as the current Great Lakes.
