Geology

The spectacular landscape of the proposed Geopark owes its uniqueness to its long and varied geological history. Faults and mountain building events converge to sculpt the majestic Percé Rock and its surrounding hills, cliffs and coves. Five distinct geological periods are visible in the Geopark: The Cambrian (542-489 My), the Ordovician (489-443 My), the Silurian (443-418 My), Devonian (418-359 My) and Carboniferous (359-299 My).

 

It is possible to see faults which have displaced rocks, the effects of erosion (especially on Percé Rock), the morphology of Percé from the summit of Mont Saint-Anne and remnants from the geological history of Percé (fossils, glacial phenomena).
