Madeira (ship)
On November 28, 1905, Madeira, under tow of the steamer William Edenborn, was caught in a fierce storm with winds around 70 to 80 miles per hour, blowing snow onto the deck and kicking up huge swells.The captain of William Edenborn feared the loss of his ship and made the decision to cut the Madeira loose.[3] In 1955, divers from the Frigid Frogs dive club in Duluth, Minnesota, first explored the wreck, but reported that there was little or no treasure on board.In 1960, a salvage company purchased the rights to the ship from the Pittsburgh Steamship Division of U.S. Steel Corporation.Divers removed one of the anchors and the ship's wheel, which were sold to the nearby Split Rock Trading Post.
