The Parks / Ontario / Georgian Bay Islands National Park



 

These smooth ‘whale-backed’ islands were once mountains taller than our present-day Rockies. Millions of years of building and erosion created mineral layers of pink, black and white crystal now exposed as wavy patterns of colour in the rocks. A great tropical sea lapped against these mountains for 200 million years ultimately leaving the fossilized shells of sea mollusks, corals and crustaceans embedded in limestone on the sea's floor. The popular caves and ‘flowerpots’ that draw tourists to Flowerpot Island are excellent examples of the effects of erosion on limestone.
