For more than two centuries, treasure hunters have excavated Oak Island in Nova Scotia, Canada, searching for something supposedly buried beneath the ground. The mystery began with accounts of an unusual depression and a deep shaft that became known as the Money Pit.

This episode examines what is historically documented, what later treasure stories added to the legend, and why repeated excavations have produced intriguing artifacts without revealing the enormous treasure generations of searchers expected to find.

Was something deliberately hidden beneath Oak Island, or have centuries of excavation transformed an uncertain discovery into a mystery that now sustains itself?
