The ‘Isle’ of Mont St.-Michel

Supertide phenomenon covers causeway to French coastal community.

Once every 18 years, a supertide turns France’s famed Mont St.-Michel into an island — a visitor attraction that never gets old.  Very high tides are part of the reality along France’s entire northern  coast, the periodic supertide is especially dramatic. One such tide occurred yesterday. Legend has it that the supertide comes in the pace of a horse’s gallop. It briefly turns into an island, while the day’s low tide allows people to walk on the expansive flat seabed off the coast of Normandy. Mont St.-Michel is a UNESCO World Heritage Site. Some 30,000 people reportedly came to Mont St.-Michel to witness the first supertide of the 21st century.

Actually, the supertide effect is evident elsewhere as well, including the Bay of Fundy on the Atlantic Coast between New Brunswick and Nova Scotia, Tierra del Fuego off the southern tip of South America, the northern coast of Australia and the Bristol Channel in Britain.
