With its giant, surprisingly-shaped monoliths, Anse des érosions (Île Quarry) has an air of mystery…

  • Monoliths

    Monoliths on the Mingan Islands.

    These unusually shaped rocks decorating the Mingan Archipelago are made of limestone, which formed on the sea bottom about 500 million years ago.

    After the end of the last glaciation, the ground rose, as did the sea level, depositing elements onto the loose soil.

    Waves, wind and periods of melting shaped the landscape, creating the islands and monoliths so typical of Mingan.

  • Coral reefs in Québec...

    Ammonite fossil.

    The Mingan Archipelago hides many other geological treasures. This is where the oldest fossilized coral reefs in the world were found!

    These reefs were formed some 465 million years ago, when the area was covered by the sea.

    Over time, layers of debris were deposited on the reefs. The pressure of their weight combined with chemical reactions transformed the reefs into fossils.
