"The Industry" was found more than 70 miles off the mouth of the Mississippi River.

Endurance belonged to Sir Ernest Shackleton, who led a crew of 27-men and 69 dogs who attempted to traverse the continent via the South Pole and establish a base on the coast of the Weddell Sea.

A mysterious wreck lays about 40 miles offshore St. Augustine, which for decades had no name other than the Bear Wreck. A storm ended its passage prematurely, and none of the 32 people on board were ever seen or heard from again. After nearly 100 years underwater, some structure remains and is host to big fish, including sharks and grouper. Local Diver Joe Kistel, from Think It, Sink It, Reef It, recently showed whats left, which includes the ships bow and boilers.
