Chasing Everglades Treasure

Aug 20225 sites✓ transcript

Josh Gates ventures into Florida's swamps and coastal towns to hunt the hidden fortune of the Ashley Gang, a family crime syndicate that terrorized the Sunshine State from 1914 to 1924. Led by John Ashley, dubbed the "King of the Everglades," the gang robbed over 40 banks—nearly double the number hit by John Dillinger—and amassed what experts estimate would be millions in today's currency through bootlegging, piracy, and murder. New research for a museum exhibit has unearthed fresh clues, including a lost document pointing to a potential treasure island and evidence of an entire lost town that may have housed the gang's hideout. Gates teams with treasure hunters and historians in Stuart, Florida, where the Ashley legacy remains deeply embedded in local culture, to pursue both the physical loot and the truth behind this lesser-known chapter of American crime.

Mysteries of Moses

Aug 20229 sites✓ transcript

Josh Gates embarks on an epic investigation across the Middle East to determine whether Moses was a real historical figure and if the events of Exodus have any archaeological basis. The quest takes him from opening a long-sealed tomb in Egypt that might hold clues to Moses' identity, to exploring ancient mines where inscriptions could point to fleeing Israelites, to climbing a remote mountain peak believed by some to be the true Mount Sinai. Along the way, Gates teams up with Egyptologist Aidan Dodson in Coptic Cairo, investigates a mysterious man-made structure in the Sea of Galilee, and examines competing claims about where Moses is actually buried—all while asking whether this legendary prophet, lawgiver, and freedom fighter ever walked the earth.

The expedition then shifts to the Sea of Galilee, where Gates dives to investigate a submerged structure that some claim connects to the Exodus narrative, and travels to a remote site said to house Moses' tomb—a location that raises immediate questions about separating historical figure from religious legend.

Gates explores sophisticated engineering works carved directly from hillsides, discovering construction so advanced it challenges assumptions about pre-Roman Italy. The central mystery: could this largely forgotten civilization have laid the groundwork for Rome's greatest achievements, from roads to engineering marvels?
