Summary

Description	English: Winch aboard the shipwreck of Kyle Spangler in Lake Huron, Thunder Bay National Marine Sanctuary, Michigan, United States. Caption in source document: A 2008 photo of the same winch…, covered with a thick layer of quagga mussels. The difficulty of archaeologically documenting the winch is dramatically apparent, as is the potential for decreased recreational value.
