When the glaciers moved across Ontario during the last ice age, they scraped uncountable tons of soil exposing the Canadian Shield rock and forming the thousands of lakes that are found in Ontario today. When the glaciers melted, very unique land formations were left behind, which come under three main classifications: Drumlins, Eskers and Moraines.

Eskers are ridges of sand and gravel deposited by streams that flowed through tunnels at the base of the glacier.
