This is a tugboat that burned at the Salt Dock in 1923. The wreck is just down from the Tag-a-Long trailer park, south of the Marine City DNR boat launch. There is a lot of machinery here, including a giant boiler laying on its side.
WILLIAM DICKINSON searched Lake Michigan for the ill-fated CHICORA in February 1895. In August 1904, the DICKINSON was involved in an incident in Chicago where a car fell off the Rush Street drawbridge which had opened to allow the tug to pass. The DICKINSON turned around and plucked most of the car’s occupants out of the Chicago River.
