The Dunkirk Schooner Site is an underwater archaeological site in Lake Erie, about twenty miles off Dunkirk in western New York, where cold freshwater has preserved the wreck of a wooden Great Lakes schooner. The two-masted vessel was about eighty feet long with a nineteen-foot beam, but its identity remains uncertain. One theory links it to the Caledonia, built near Detroit in 1799, which served in the fur trade, changed hands during the War of 1812, and may later have been renamed the General Wayne and used to carry runaway slaves to Canada before sinking before 1850. Another possibility is a grain-carrying schooner from the 1830s. The site offers a rare window into early Great Lakes shipping, trade, wartime transport, and possible antislavery activity.
