Season 13, Episode 9 Overview: So Close Yet Sonar
The Curse of Oak Island continues its methodical search in Season 13, Episode 9, an instalment that prioritises investigation and evidence over spectacle. Titled So Close Yet Sonar, the episode focuses on analysis, incremental discoveries, and groundwork that may shape future breakthroughs rather than delivering immediate answers.
Swamp Excavation Reveals More Worked Wood
The episode opens in the swamp, where excavation resumes with Billy Gerhardt once again playing a central role. As digging continues, multiple pieces of buried wood are uncovered.
Individually, these finds are unremarkable. Collectively, however, they add weight to a long-standing theory: the swamp was deliberately modified rather than formed entirely by natural processes. The repeated discovery of worked wood suggests organised human activity dating back centuries, even if its exact purpose remains unclear.
Lab Analysis Raises Questions, Not Conclusions
Attention then shifts to the research lab, where Emma Culligan examines the folded metal object recovered in the previous episode. Through metallurgical analysis, she determines that the artifact is primarily copper and likely dates from between the 16th and 18th centuries.
Crucially, Emma explains that its structure does not match that of a conventional coin. While Rick Lagina explores potential historical links to European activity during that period, a visiting researcher offers an alternative interpretation, suggesting it could still represent a form of currency or trade item. The team ultimately agrees that the evidence is inconclusive and that further corroboration is required.
Lot 8 Finds Point to Trade Activity
Metal detecting on Lot 8 produces modest but contextually important discoveries. The team recovers a small metal fragment and a lead bag seal—an object historically associated with shipping, trade, and commercial goods.
Although neither item points directly to hidden treasure, both reinforce the idea that Oak Island may have been part of wider trade or supply networks. These finds continue to build a picture of sustained human presence rather than isolated or accidental visits.
Money Pit Drilling and the Peacock Anomaly
The episode then returns to the Money Pit area, where drilling continues in a zone known as the Peacock. Core samples bring up thick, muddy material, which is examined for indications of structural disturbance.
A camera lowered into the borehole offers limited visibility, prompting the team to deploy sonar equipment. The sonar reveals a small underground void measuring less than two feet. While far too small to confirm a chamber or vault, the void is logged as a notable anomaly—one that may justify closer inspection as drilling continues.
A Measured Step Forward
The episode closes on a note of cautious optimism. No definitive discoveries are made, but valuable data is gathered that helps refine future targets and eliminate unproductive areas.
Season 13, Episode 9 stands out as a quieter yet meaningful chapter. Billy Gerhardt’s increased presence underscores the importance of hands-on excavation, and viewers who favour the investigative and analytical side of the series will find this episode particularly engaging. While major revelations remain out of reach, the search presses on with renewed focus and discipline.
