Presqu'ile Provincial Park

Formation of Presqu'ile

It is only in the last 10,000 years that the Presqu'ile we know today was formed. Presqu'ile is a landform known as a tombolo. A tombolo is formed when an island is connected to the mainland by a sandbar. The Presqu'ile tombolo is a fascinating formation, unequaled in size, complexity, and degree of development on the Great Lakes.
