Near Swink was the discovery of Oklahoma’s only steamboat wreck. The steamboat Heroine sank in the Red River on May 7, 1838, after hitting a submerged snag. The Red River changed course in the early 1840s, leaving the Heroine buried in what became a pasture. In the 1990s during a period of flood, the river moved again and Heroine reappeared in a riverbank. In 1999 the Oklahoma Historical Society and the Institute of Nautical Archaeology at Texas A&M University collaborated on a dig of the site. The excavation occurred between 2001 and 2008. Reconstructed segments of the boat and its machinery, along with artifacts from the wreck, are now in the Oklahoma History Center in Oklahoma City.
