Destination: The Waters off Baja, Mexico

Expedition: In 1853 the Steamship Independence hit rocks off Isla Margarita and went ablaze. Although the crew members heroically fought to save the passengers--including one Tom Sawyer, who served as inspiration for Mark Twain's book--132 drowned. For decades, underwater archaeologists have been combing the waters off Baja, Mexico for the wreck of the Steamship Independence. Peter Tattersfield and his international team of explorers are poised to uncover it.
