Recent strong winds and waves have delivered part of a shipwreck in the Sleeping Bear Dunes National Lakeshore. The piece measures 15-feet wide and 40-feet long.
Lakeshore staff and volunteers are working to identify the wreckage.
Laura Quackenbush, a museum technician with Sleeping Bear, says the ship was probably built sometime after the mid 1800s.
"Because of its dark color we're pretty much sure it's white oak, which was the standard for construction of boat timbers and frames.
"The major construction pieces of a boat were often white oak, and when they're wet these are dark colored. And they do survive a pretty long time because white oak is naturally rot resistant and pretty tough wood."
The wreckage washed-up on the beach west of Sleeping Bear Point about two-and-a-half miles from Glen Haven.
