Did You Know?

A dark shinning rock outcrop glistens from the rain.

The last glacier receded from this area about 10,000 years ago.  As the glaciers melted, they formed a huge lake which  permanently separated Isle Royale from the mainland.  Today, the coolness of the big lake (Lake Superior) creates a climate in which artic plant species grow.
