Description: The Oscar T. Flint caught fire just after leaving Alpena, burned to the waterline, becoming a total loss about 4 miles east of the Thunder Bay River. Except for the bow, much of the ship's hull is still intact, along with much of the limestone cargo. The Flint's boiler was dynamited and the propeller lies buried beneath the stern post. The anchors and windlass seen at the bow were reportedly brought there from the wreck of the schooner Lucinda Van Valkenburg.
Thunder Bay National Marine Sanctuary: Enjoy diving the wrecks of Thunder Bay, but always respect the past. State and federal laws prohibit removing or disturbing artifacts. Future generations are depending on us to leave historic shipwrecks intact. Please take only pictures and leave only bubbles.
The Thunder Bay National Marine Sanctuary maintains seasonal moorings at many shipwreck sites. Available from May to September, the moorings make for safer diving and also protect shipwrecks from anchor damage. Sanctuary regulations require vessels to use moorings when present.
