The Vessel and Her Loss
Walter L. Frost was a wooden package freighter built in 1883 to the largest dimensions permitted by the Welland Canal, carrying grain and general merchandise between Chicago and Ogdensburg for twenty years. On November 4, 1903, dense fog caused her to run aground on South Manitou Island; all 21 crew were rescued by the island's Life-Saving Service station. In 1960, the freighter Francisco Morazan ran aground on the same shoal directly atop the Frost's remains, further breaking up the older wreck.
