Manmade Evidence Leads to BIG Treasure (Season 12) | The Curse of Oak Island
New Clues Unearthed in Oak Island Swamp
A Man-Made Timber Discovery in the Northern Swamp
While investigating the northernmost region of the Oak Island swamp, Rick Lagina and his team uncovered a large, weathered timber. Measuring approximately 10 to 12 inches in width, the timber closely matched descriptions given by the late surveyor and treasure hunter Fred Nolan, who believed a man-made wall or dam once existed in the area.
This discovery has fueled speculation that the team is nearing a structural feature—possibly the long-theorized wall—that may have played a crucial role in transforming the natural landscape into a deceptive swamp to hide valuable artifacts or treasure.

Evidence of Intentional Construction
As excavation continued, the team uncovered several large boulders aligned in a straight pattern. This alignment strongly suggested intentional placement rather than natural deposition. The configuration of boulders, combined with nearby wooden elements, supports Fred Nolan’s decades-old theory that someone constructed a dam or seawall to manipulate the swamp environment.
Further digging revealed even more wooden pieces and boulders appearing to connect structurally, creating a pattern reminiscent of a wall. The regular spacing and the way some timbers connected multiple stones implied a deliberate design.
Possible Connection to Fred Nolan’s Dam Theory
Fred Nolan long believed that a wall or dam had been built to alter water flow and conceal buried work. Now, with substantial evidence of human-engineered features, Rick and his team are revisiting Nolan’s original claims with renewed seriousness.
A piece of timber discovered within the structure showed clear signs of having been axe-cut, ruling out modern tools and supporting the notion of historical construction. Rick emphasized that if the structure is indeed a wall, it could be one of the most significant finds in the swamp to date.
Alignments That Raise Big Questions
Tom Nolan, Fred’s son, joined the team on-site and identified a line of boulders with a distinct offshoot—again suggesting intentional construction. The idea that this feature could have served to keep water out, regulate flooding, or create an artificial swamp is under serious consideration.
Steve Guptill, the team’s surveyor, was called in to map the boulders’ orientation and elevation. Upon inspection, he proposed the feature might be a seawall, a structure typically built from rock or wood to protect coastal areas and control water flow.

Could This Be the ‘Barrage’ on the Templar Map?
This newly uncovered formation may also connect to a mysterious 14th-century map shared by researcher Zena Halpern in 2016. The map referenced a “barrage”—a French term for a dam or barrier—at the north end of the swamp. Rick noted that the structure’s alignment and function could support Halpern’s theory, possibly lending legitimacy to the ancient map and Fred Nolan’s interpretations.
Next Steps in the Search for the Wall
As the team continues excavation and surveying, attention is turning toward mapping the full extent of the rock and timber alignment. The goal is to determine whether this feature connects to other known constructs in the swamp and to assess its potential role in shaping the island’s mysterious landscape.
If confirmed, the discovery of a seawall or dam would not only validate Fred Nolan’s long-held beliefs—it could also redefine the history of Oak Island and the search for its legendary treasure.
