Expedition Unknown | The Search For Sir Francis Drake's Lost Treasure

Sir Francis Drake’s story is the stuff of legend, and two monumental mysteries that surround his life might be on the verge of being solved. The largest treasure he ever stole was his daring heist of a silver-laden caravan crossing Panama in 1573. Now, a researcher retracing his routes on historic maps believes he’s found the jungle hiding place of Drake’s buried fortune. And an archeologist believes he is on the brink of making an even greater find: the final remains of Sir Francis Drake himself.
