The western shore of Trout Lake is registered as a Nature Reserve to protect the Trout Lake Moraine. A Moraine is a very unique land formation, which hosts unique plants and animals that are not common elsewhere in the far north.

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.
