While enroute from Bay City to Chicago with a cargo of barreled salt, the crew of the three masted schooner Margaret A Muir noticed their vessel settling in the water at about 7:30 on the morning of 9/30/1893, as they attempted to bring the Muir into stays. The seven man abandoned the schooner in their yawl. Sunday morning the captain of the tug Goldsmith reported that the main mast of the Muir was still standing about ten feet above the lake's surface. Wreckage from the Muir including her cabins, hatches, and portions of her deck was reported to have been washed ashore. Specifically, the Door County Advocate 7/21/1894 reported the U.S. tug Lorena removing and disposing of a portion of the wreckage, probably a portion of the hull.
