Join the team as they uncover startling new clues in the search for a legendary treasure hidden beneath Smith County. From mysterious concrete beams to cutting-edge radar scans, the hunt for the elusive flood tunnel is heating up with each groundbreaking discovery. Building off the scientific revelations from the last three seasons that large sources of silver and gold lie deep in the Money Pit area, the Laginas and their team continue to try and pinpoint the location of the legendary treasure by applying cutting edge technology such as ‘Muon Tomography’ and conducting large scale dig operations. The team will also perform much wider-scale digs across the body of the swamp and will extend their outreach and exploration of European countries in an attempt to reveal the origins of the Oak Island mystery.
