At the Money Pit area, Choice Drilling arrives on the island and sets up its rig while Steve Guptill and Doug Crowell use GPS equipment and a survey map to locate borehole F6, the first of many holes the drilling team has been contracted to punch that season. Nearby, Marty Lagina, Charles Barkhouse, Terry Matheson, and Scott Barlow examine the first core samples to come up, and Barlow reports that one of the drills dropped into a void extending from 206 to 213.5 feet below the surface. The core from that depth contains only loose wet earth, and Marty concludes no true open void exists at the site. The team decides to abandon the hole and move on to the next.
Members of the team gather at the West Hill feature on Lot 11, the water-filled depression identified as a potential area of interest by theorists Corjan Mol and Chris Morford in the previous episode. Dr. Ian Spooner oversees the investigation, tasking Gary Drayton with scanning the surroundings for metal artifacts while others clear vegetation with chainsaws. When Drayton finds nothing of note, Billy Gerhardt excavates the dirt mound beside the pond with a backhoe. The mound proves entirely devoid of rocks, but beneath it the team uncovers stones arranged in a deliberate pattern that Dr. Spooner compares to the Paved Area in the swamp.
In the War Room, the team connects via Skype with GIS expert Erin Helton and researcher Judi Rudebusch, a friend and research partner of the late Oak Island theorist Zena Halpern. Helton presents an analysis of the anchor points suggested by Halpern's mysterious map of Oak Island, using the positions of the Nolan's Cross boulders, a drilled stone discovered by Gilbert Hedden in the 1930s, and other landmarks to identify geometric alignments across the island. Comparing her findings with a map published in the June 1939 issue of Popular Science, Helton plots what she believes is the location of the original Money Pit, placing it just three feet from Borehole RF-1.
On Lot 13, Rick Lagina and Gary Drayton metal detect near the East Hill feature and recover an old Victorian-era iron lock that Rick notes lies close to the former home of Oak Island landowner Anthony Graves. The team then heads to the swamp to investigate Helton's anchor points. At the western location they find a small white boulder buried deep in the ground bearing a tiny depression on its surface. At the northeastern anchor site, along the Boulderless Beach, they locate a similar stone with a t-shaped marking, though Alex Lagina suspects the mark is natural. Marty expresses skepticism about the anchor stones but agrees the locations warrant further study.
