Bigger Digging
Armed with a two-million-dollar budget, the team launches its most ambitious Money Pit excavation to date, sinking massive five-foot-wide steel caissons deep into the earth. The C-1 shaft punches into a 21-foot void at 171 feet, where divers encounter murky water and tantalizing metal detector hits. Meanwhile, the team visits the Franklin D. Roosevelt Presidential Library, uncovering documents that prove the future president was personally invested in the Oak Island mystery. Research into former landowner Samuel Ball, an enslaved man who became a wealthy citizen after settling on the island, raises questions about what he may have found. The season ends with four shafts drilled but the treasure still just out of reach.
