Lusk Cave is a marble cave and natural geological phenomenon that has been thousands of years in the making. During the Ice Age, Canada went through four major glaciations. The last of which being the Wisconsin Glaciation, saw ice forming over almost all of Canada and as far as the state of Wisconsin in the United States. When the Wisconsin Glacier melted about 12,500 years ago, water trapped under the melting glacier was forced into cracks in the rocks. The marble of Lusk Cave eroded more quickly than surrounding rocks, causing a series of tunnels to form. Since then, the Lusk Stream has continued to shape the cave (NCC).
There is two sections to the cave. The first section the water is ankle high, the second section is waist high. At the end of the second section right before the exit is a small opening between the water and the ceiling, making you dive underwater to the exit. It will be hard for people who are claustrophobic.
