Shipwrecks

Sable Island is famous for the large number of shipwrecks. An estimated 350 vessels are believed to have fallen victim to the island's sand bars. Thick fogs, treacherous currents and the island's location in the middle of a major transatlantic shipping route and rich fishing grounds account for the large number of wrecks. The first recorded wreck was in 1583, the last in 1999. Few wrecks are visible on the island as the ships are usually crushed and buried by the sand. The large number of wrecks have earned the island the nickname "Graveyard of the Atlantic", although the phrase is also used to describe Cape CodCape Cod
