The team teleconferences with Vanessa Lucido of ROC Equipment to discuss plans for drilling in the Money Pit area, settling on seven- to eight-foot caissons that can be deployed faster than the larger ten-foot models. In the swamp, excavation continues with the recovery of axe-cut wood chips and what appears to be a stake driven through a board. The discovery recalls Fred Nolan's finding of survey stakes in the swamp that were carbon-dated to the 1500s. Further work reveals planks and boards stretching a considerable distance, and Laird Niven recommends that Dr. Ian Spooner date the wood samples.
In the War Room, Terry Deveau of the New England Antiquities Research Association presents documents from the Connecticut Museum of Culture and History. The papers belong to William B. Goodwin, a wealthy Hartford historian who spent summers in Chester, Nova Scotia and worked with treasure hunter Fred Blair on Oak Island during the 1930s. Among Goodwin's 26 boxes of papers, a map was found that appears to be his sketch based on a map owned by Blair, the original of which has never been located. The team interprets the map as indicating three separate treasure caches on the western side of the island on Lots 1 and 21, land that once belonged to the McGinnis family.
The team takes the map into the field, locating several landmark stones including ones with X carvings and squares. Metal detection expert Gary Drayton scans around and beneath each stone without registering hits until they reach one described as having the top cleaved off. Here Gary picks up a signal and pulls out an iron cribbing spike, found near the spot where the team previously discovered swages that Carmen Legge identified as mining and tunneling tools.
On Lot 5, archaeologist Fiona Steele continues uncovering glass, pearlware, high-glazed brick, and rosehead spikes near the brick kiln foundation. In the swamp, Dr. Spooner observes layered, step-like formations leading down to a platform structure at the same elevation as the nearby cobble path. Additional survey stakes are discovered, and Spooner agrees to attempt dating them.
