Underwater explorer Barry Clifford said he found sunken off Haiti what he thinks is the wreck of Santa Maria, Christopher Columbus’ long lost flagship from his first journey to the Americas. Clifford and his team used high tech sonar scanning and metal detection devices to examine the ship’s remains. Most of the ship is intact and excavation will be possible with assistance from the Haitian government, Clifford said. In what could be one of the most important historical discoveries in history, Clifford said he is confident the wreck is the Santa Maria.
