Wreck of last U.S. slave ship remains mostly intact on Alabama coast, researchers say

Researchers studying the wreckage of the last U.S. slave ship, buried in mud on the Alabama coast since it was scuttled in 1860, have made the surprising discovery that most of the wooden schooner remains intact, including the pen that was used to imprison African captives during the brutal journey across the Atlantic Ocean.

While the upper portion of the two-masted Clotilda is gone, the section below deck where the captured Africans and stockpiles were held is still largely in one piece after being buried for decades in a section of river that hasn't been dredged, said maritime archaeologist James Delgado of the Florida-based SEARCH Inc.

At least two-thirds of the ship remains, and the existence of the unlit and unventilated slave pen, built during the voyage by the addition of a bulkhead where people were held as cargo below the main deck for weeks, raises questions about whether food and water containers, chains and even human DNA could remain in the hull, said Delgado.
