The Niagara Escarpment is best known for the waterfall that plunges over it—Niagara Falls—but it actually extends west across the Niagara Peninsula, north across southwestern Ontario, across Lake Huron, and southwest into Wisconsin, stopping just short of Chicago.

Along the Bruce Peninsula, the escarpment runs along Georgian Bay, where the waves pound away at the exposed limestone with tremendous force. On top, trees and other vegetation attack the rock from above.
