Oak Island Season 13, Ep20: What They Found Beneath This Massive Boulder Shocked the Oak Island Team
For more than 225 years, Oak Island has been one of the world’s most perplexing mysteries. The quest for hidden treasure has consumed fortunes, lives, and careers. Over the decades, countless expeditions have failed to unlock the island’s secrets, and with every dig, the question of what lies beneath has only grown more tantalizing. However, Season 13 of The Curse of Oak Island may have just unearthed the breakthrough that could change everything. In the latest shocking turn of events, a discovery on Lot 8 has sent ripples through the treasure-hunting community, with the possibility of an ancient vault or even something far older than anyone had imagined.
The Discovery That Changed Everything

The story of Oak Island’s mystery is well known: a treasure hoard buried deep within the island, hidden by some unknown force, thwarting generations of explorers. But in the Season 13 finale, everything changed. What appeared to be just another routine excavation on Lot 8 soon turned into the most significant moment in the island’s history. The team uncovered a massive, 40,000-pound boulder that had been carefully placed over a tightly packed ring of smaller stones. Beneath this boulder was a sealed shaft, one that had been backfilled with soil and left undisturbed for centuries. This wasn’t just another pile of rocks or an ordinary geological feature—it was a deliberate construction.
The boulder’s placement was precise, and the surrounding stones suggested a purposeful design. Fiona Steele, the archaeologist on the site, confirmed that this was not a natural formation. It was a human-made structure. The significance of this discovery was monumental—someone had gone to great lengths to hide whatever lay beneath. And what was buried underneath, it seemed, had been hidden with a level of care and knowledge that pointed to an extraordinary operation. It wasn’t just treasure hunting; this was something far more deliberate and sophisticated.
The Silver Reading and the Evidence of Human Activity
As the team continued to excavate, they found more shocking evidence that something significant lay hidden beneath Lot 8. Dr. Ian Spooner, a geoscientist, used an X-ray fluorescence (XRF) scanner on the soil beneath the boulder. What he uncovered was silver—an unexpected find in a location that had never shown such readings before. The silver wasn’t just an anomaly; it was sitting inside a carefully sealed space, suggesting that whoever buried it had purposefully concealed valuable items. This wasn’t just the result of random drifting; the silver had been intentionally placed in this spot.
But it didn’t stop there. The team also uncovered traces of lead, another indication of underground fires used for ventilation, a method employed in medieval European mining operations. This discovery was critical—such fires would have been necessary for deep shaft mining, where oxygen was scarce. The technique was used in ancient and medieval mines, specifically in Cornwall, where large underground operations required continuous airflow to keep workers alive. This discovery raised a startling possibility: the builders of the Oak Island vault had the knowledge and resources to construct a sophisticated underground system, possibly dating back to the medieval period.
The Templar Connection: A New Layer of Mystery
As the evidence mounted, the team began to consider the possibility that the vault beneath Lot 8 could be connected to the Knights Templar. For decades, theories surrounding Oak Island have included the Templars, with their vast wealth and secretive nature. The intricate engineering of the vault and its connection to European mining methods raised the question: could the Templars have hidden their treasure on Oak Island? The presence of a coin dating from the 1300s, likely from the time of the Templars, further strengthened this theory.
The Templars were known to have excavated beneath the Temple of Solomon in Jerusalem, uncovering artifacts and relics of great value. It’s not far-fetched to think that they might have used Oak Island as a hiding place for some of their wealth after fleeing Europe during their suppression. The discovery of a Roman coin, the use of medieval European mining methods, and the architectural style of the stone feature suggest that multiple groups, possibly including the Templars, could have been involved in creating this hidden vault.
The Vault’s Location and What Lies Beneath
The team’s next step is crucial—carefully excavating the area beneath the boulder to uncover what lies below. With every layer of soil removed, the team has been more confident that they are on the brink of uncovering the island’s greatest secret. The vault, if it exists, could contain priceless treasures—gold, silver, and perhaps relics of historical significance.
The risk is high. The flooding tunnels that have thwarted previous expeditions could strike again, and every inch of excavation is closely monitored. Rick and Marty Lagina, along with their team, are aware of the dangers, but they know that this could be the breakthrough they’ve all been waiting for. For Rick, the discovery is more than just about treasure—it’s about proving the theories that have driven his obsession with Oak Island for years.
As the team continues to dig, one question remains: will they uncover a treasure worth $150 million, or will the island’s secrets remain buried for another generation to uncover? What is clear is that this is no longer just a treasure hunt—it is a race to uncover history itself. The next steps in the excavation could answer questions that have plagued Oak Island explorers for over two centuries. The discovery beneath Lot 8 could finally reveal the truth about what lies hidden on this mysterious island, or it could lead to even more questions.
The Future of Oak Island
As the excavation on Lot 8 intensifies, so does the anticipation surrounding Oak Island’s ultimate discovery. The leaks from Season 13 suggest that this could be the turning point in the long-running mystery. The possibility of uncovering a $150 million treasure vault, possibly linked to the Templars or other ancient explorers, has sparked the imaginations of treasure hunters worldwide. But the real question is whether Oak Island will finally give up its secrets, or if it will remain a tantalizing mystery forever. Stay tuned as the team digs deeper, inching closer to a discovery that could change history forever.
