Located on Cap-aux-Meules, on the Magdalen Islands, these red rocks contrast magnificently with the blue of the ocean.
St. Lawrence River
The St. Lawrence springs from the Great Lakes. Between the mouths of lakes Ontario and St. Pierre is the river section. Here, the St. Lawrence is generally only a few kilometers wide.
Then, up to Pointe-des-Monts is the estuary. The St. Lawrence widens progressively to more than 40 km from shore to shore.
Finally, up to the Cabot Strait is the Gulf, a veritable inland sea linked to the Atlantic Ocean!
Cliffs and beaches
In several locations on the Magdalen Islands, the sandstone cliffs are deep red in colour, due to their chemical composition: 99% quartz grains, cemented by a layer of iron oxide (in other words, rust).
Due to the wind and waves, these grains are separated from one another and washed of their thin film of iron oxide. Then, they once again become grains of white sand which are deposited on the shorelines and beaches.
