America Underwater

The Wreck of the "Chester A. Congdon," Lake Superior, Michigan
Depth: 109 feet
In November of 1918, this bulk steel freighter ran aground in a heavy fog. In the next two days, gale force winds snapped the 532-foot vessel in two. The pilothouse sank into deep freshwater, where it is well preserved to this day.
