Terry Deveau, Alex Lagina, and Charles Barkhouse are at the Money Pit where the team has begun drilling Borehole CN11, positioned 27 feet west of the Garden Shaft and in the center of what Marty Lagina has named the Blob. The area measures roughly 70 by 25 feet and is where water testing indicates the highest gold levels, concentrated at a depth of approximately 80 to 120 feet. A core sample from 108 to 119 feet reveals something Terry calls very unusual: fine sand forced into tighter material under pressure, a classic indicator of human activity. Rather than go deeper, Terry recommends moving to another site after collecting a water sample from the borehole for testing.
On Lot 5, Jack Begley, Miriam Amirault, and Helen Sheldon continue excavating the stone feature near where the team found ancient tools and a Roman half coin that could be 2,000 years old. The previous week Rick Lagina and Gary Drayton found pottery dating to the early 1700s, and Helen recovered a copper nail. Craig Tester arrives to check progress, and Jack reports they have found significant amounts of charcoal. Helen tells Craig that the stones on the edges of the feature are packed tightly and do not move, unlike the loose fill in the center, forming what she describes as an inner wall. Miriam then pulls a clay pipe stem from within the feature. Helen explains that clay pipes were used from the late 1500s to late 1800s and the borehole diameter can help narrow the date. Miriam notes that Rick had wondered why no clay pipes were found during excavation of the stone road in the swamp. When Rick and Gary arrive, Helen tells them the rocks in the middle were used to fill in the structure but the sides are firmly set, and that this is the oldest European deposit they have found on the island.
In the War Room, Craig and Rick discuss a well on Lot 26 that Rick and Dan Blankenship found years ago with no ice on it despite below-zero temperatures. The lot was purchased in 1784 by Captain James Anderson, an American Freemason some believed smuggled treasure to Oak Island during the American Revolution. The lot later passed to Samuel Ball in 1788. Craig tells the group that he and Dr. Ian Spooner went out and collected water samples, and Spooner reports the well is one of the only locations outside the Money Pit where silver was found. He describes the construction as crude and "rough." Rick wants the well cored and dated. On Lot 26, Spooner and archaeologist Laird Niven take core samples using a piston corer that works like a syringe.
In Liverpool, Nova Scotia, Rick, Charles, and Corjan Mol visit stone carvings after being contacted by Isaac Rafuse, who believes they may relate to Oak Island. Corjan says the carvings remind him of Fontarcada. At the site, Isaac and Nick Fralic show them a triangle shape carved near the water. Isaac says the carving has been there as long as anyone can remember and could be a British broadhead, a symbol used since the 14th century to signify ownership by the British government or nobility. Rick and Corjan point out differences between the carving and a broadhead, and Corjan explains that broadheads were never put on rock. He identifies the symbol as a goose paw, the mark of Masonic stonemasons for the Knights Templar in medieval Europe, found on cornerstones of confirmed Templar churches in northern Portugal, Spain, southern France, Italy, and Sardinia. Isaac then leads the group to another stone bearing a cross, a circle, and a half circle with a dot. Corjan identifies a globus cruciger, a circle with a cross on top representing God or Jesus, dating to the fifth century as a symbol of Christianity's dominion over the world. Rick says the team will research how the carvings might connect to Oak Island.
In the War Room, Dr. Spooner presents results from the well core. He shows the team a photograph of the sample containing small stones and twigs, and points out the piece of wood he used for testing, which was likely in the dirt at the bottom of the well when it was constructed. The wood dates to 1028 to 1172 A.D. Doug Crowell reminds the group that the paved area in the swamp was also dated to the 1200s, raising questions about the broader story the dates are beginning to tell.
