Somewhere in the Mojave Desert, according to a persistent legend, lies the wreck of a Spanish galleon loaded with pearls, stranded far from any coastline. This episode of Myth Hunters follows the story back to 1870, when prospector Charley Clusker organized an expedition to find the ship, convinced enough by old accounts and desert rumor to risk his life searching dry lakebeds and canyon washes for a hull that should not exist there. The film traces the legend's roots through Spanish exploration history, Native American oral tradition, and the accounts of later desert wanderers who claimed to have glimpsed timber or metal fittings jutting from the sand. Historians and desert researchers weigh the physical evidence against the geological history of the Mojave, once covered by ancient lakes, to explain how a ship story could take hold in a landscape now defined by heat and drought. Location footage of the desert terrain grounds the mystery, while the narration keeps returning to the same question: did Clusker chase a real wreck, or a myth built out of desperation and desert light?
