Rick Lagina and the team mark the location of Borehole DN11.5 in the Money Pit. Steve Guptill pinpoints the exact spot, and Rick tells Mike Tedford of Choice Drilling that based on water testing this is a prime target inside the Baby Blob, with a potential tunnel at a depth of 95 feet. Colten brings over a core from 78 feet, and then Mike reports that at 90 feet the drill broke through into open space. Terry Deveau tells Mike to hold until Rick and Marty Lagina can assess the situation. When they arrive, Terry explains this appears to be the top of the tunnel the team has found in two other boreholes, running east to west just beneath the Garden Shaft. The next core contains wood, and Dr. Ian Spooner takes a sample for testing. Marty orders the Inuktun Spectrum 120 camera lowered into the borehole. The camera passes through water and enters the void, but the screen goes completely black. Marty acknowledges it was a long shot but says they had to try.
At the Garden Shaft, Rick and Scott Barlow descend with Roger Fortin to inspect progress. Reconstruction is more than halfway to the target depth of 80 feet, with muck estimated at around 60 feet. Roger shows them a handmade ladder discovered during the rehabilitation. Scott notices one corner of the structure appears to be sinking, with a beam "running downhill," though Roger says no splits have appeared in the timbers. The team plans to set up a probe drill to check for offset chambers, as Borehole A5N13.5, located 18 feet southwest of the shaft, encountered a large void 12 weeks earlier.
At the Interpretive Center, Gary Drayton, archaeologist Laird Niven, Emma Culligan, and Alex Lagina show Marty by video conference the piece of jewelry found the previous week about 100 yards from the well on Lot 26. Emma's CT scan and XRF analysis reveal a brass-iron alloy containing lead-potassium glass, with no elements indicating a date after 1850. The piece consists of two parts: a copper wire section and a floral element with lead glass. The floral design is a fleur-de-lis, a symbol adopted by the French monarchy in the 12th century to represent purity and also an emblem associated with the Knights Templar.
On Lot 26, Rick, Jack Begley, Laird, and Helen Sheldon begin investigating a rock wall near where the brooch was found. The wall is wider than others on the island and has a clear linearity. Jack notes the island was surveyed in 1762 by Charles Morris and divided into four-acre lots. Laird probes toward the pond but finds no rocks extending into the wetland and decides to set up test pits. The next day Alex, Jack, Laird, and Emma work the test pits while Jack clears vegetation from the wall to search for symbols. Alex finds charcoal in his pit, and Jack notices a tree growing directly out of the wall that could help date the structure. Marty arrives, and the group agrees that coring the tree to count its rings could provide a timeline for the wall and the nearby well. At the Research Center, Rick, Marty, Scott, and Alex meet with Roger to plan probe drilling from inside the shaft. Roger says the program will drill 12 holes before moving to the next set. Marty instructs him to notify the team if any wood is found. Scott adds that once the holes are drilled, he and Steve will go down to take readings for a 3D model.
Rick and Craig Tester meet with Laird and Emma at the Interpretive Center to discuss the wood sample from Borehole DN11.5. After drying and scanning the piece with the XRF, Emma reports finding the expected natural elements along with gold. Rick tells Craig to call Marty immediately: the presence of gold in the wood could represent an evidence trail just as important as the water samples.
