Season 8 in brief

With the COVID-19 pandemic closing the US-Canada border, the American team members coordinate remotely while the Canadian crew pushes forward. The swamp delivers the season's biggest revelation: a massive stone road stretching over 460 feet along the eastern border, built with cobblestones laid over wooden cribbing in a style consistent with medieval European construction. An iron ringbolt pulled from between the stones and ox shoe nails found along the pathway suggest heavy cargo was once hauled across the island. On Lot 15, archaeologists uncover a stone structure that predates known colonial activity. At the Money Pit, water samples from deep boreholes reveal the presence of silver, giving the team a chemical trail to follow into the earth for the first time.

Research behind the season

All 25 episodes of Season 8

1 Episode 1 Remote Control The two-hour Season 8 premiere opens with the COVID-19 pandemic having shut down the US-Canada border, forcing the American treasure hunters to coordinate operations remotely. On June 17, 2020, Marty Lagina, Craig Tester, Alex Lagina, and Jack Begley meet in Marty's Traverse City, Michigan, office and connect via Skype with their Canadian partners: Laird Niven, Scott Barlow, Gary Drayton, Terry… 2 Episode 2 The Boys Are Back With the American team members still completing their mandatory 14-day COVID-19 quarantine on the Nova Scotia mainland, work on Oak Island continues under the Canadian crew. On Lot 15, archaeologists Laird Niven, Aaron Taylor, and David MacInnes resume excavation of the mysterious stone walls and uncover a large flat stone with a beveled edge and a drilled hole in its surface. Surveyor Steve… 3 Episode 3 If the Ox Shoes Fit In the War Room, the fellowship reviews plans following the Lagina brothers' return to Oak Island. Doug Crowell reveals that the wall Dr. Ian Spooner detected via sonar in the southeastern corner of the swamp is actually the top of a 9 by 9 foot shaft, a feature Fred Nolan reportedly discovered years ago when he secretly drained part of the swamp. The team agrees to excavate the anomaly using a… 4 Episode 4 Alignment On Lot 15, the Lagina brothers and Doug Crowell meet with archaeologists Laird Niven, David MacInnes, Aaron Taylor, and Liz Michels at the stone structure. MacInnes reports that his trench has reached glacial till, leaving no more of the formation to excavate, and affirms his belief that the feature constitutes the remains of a pine tar kiln. He has sent a piece of charcoal from the excavation… 5 Episode 5 The Master Plan 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… 6 Episode 6 Seaing Is Believing At the Money Pit area, Choice Drilling continues its pattern drilling operation while Terry Matheson, Charles Barkhouse, and Rick Lagina inspect a core sample extracted from borehole H5.5. The 108 to 128 foot section yields little more than water, loose earth, and crushed granite left behind from previous backfill operations. Matheson notes the team should expect more promising material below 175… 7 Episode 7 Mounding Evidence At the Money Pit, Rick Lagina, Charles Barkhouse, and Terry Matheson oversee a drilling operation that yields a striking result: 28 feet of loose material from 179 down to 207 feet in depth. Terry Matheson describes it as the closest thing to a true open void the team has encountered, and the same type of material into which the H8 caisson plug was lost three years earlier when the team believed… 8 Episode 8 High on the Bog In a War Room video conference, GIS expert Erin Helton presents a new theory built on the La Formule cipher, the coded document Zena Halpern shared with the team in Season 4. Helton interprets the cipher's instructions as describing a 522-foot corridor at a 45-degree alignment from the Money Pit, followed by a second passage of 1,065 feet. When she draws a circle of that radius from the suspected… 9 Episode 9 Rock, Paper, Serpents The team launches its first excavation of the triangle-shaped swamp after receiving government permits to drain and dig in the southeastern corner. Billy Gerhardt uses a 16-ton excavator to remove dense muck from above the massive flat stone feature that Rick Lagina and Dr. Ian Spooner discovered while probing the area, a surface measuring roughly 20 feet wide by 70 feet long atop a layer Spooner… 10 Episode 10 Connecting the Lots Excavation of the stone-paved pathway in the southeastern corner of the swamp reveals wooden cribbing beneath the massive stone surface. Archaeologist Aaron Taylor identifies beams running perpendicular and parallel in layered courses, forming an engineered substructure designed to prevent the stones from sinking into the swamp floor. Billy Gerhardt trenches along the edges while Taylor and Laird… 11 Episode 11 Rocky Road In the triangle-shaped swamp, excavation of the stone pathway continues under the supervision of archaeologists Dr. Aaron Taylor and Laird Niven, with heavy equipment operator Billy Gerhardt carefully removing material along each side. Beneath the massive stones, Billy uncovers a wood cribbing structure consisting of perpendicular beams stacked in layers, engineered to support the weight of the… 12 Episode 12 Digging Their Heels In At the wash table near the Money Pit, team members Alex Lagina, Peter Fornetti, Dan Henskee, and Michael John process spoils from borehole 8-B, located just ten feet from where 1706-dated tunnel wood was previously discovered. Among the material, they recover pieces of leather that appear to be from a boot heel and sole. Charles Barkhouse and Doug Crowell transport the leather artifacts to the… 13 Episode 13 The Fellowship of the Ringbolt In the southeastern corner of the swamp, Rick Lagina, Tom Nolan, Scott Barlow, and archaeologist Dr. Aaron Taylor continue investigating the two massive stone pathways uncovered in the triangle-shaped bog. Aaron identifies the main feature as a road leading up to the Uplands, possibly connected to a small harbor used for unloading cargo. Beneath the road surface, the team discovers a second layer… 14 Episode 14 A Bend in the Road Rick Lagina shares the recently discovered iron ringbolt with Tom Nolan in the swamp, a deeply personal moment given that Tom's father Fred spent decades investigating the triangle-shaped bog. After M.R. Chappell denied him access to the Money Pit in the early 1960s, Fred Nolan purchased eight lots across the center of the island including the swamp, where he found two large ringbolts embedded in… 15 Episode 15 Cask and You Shall Receive Along the eastern border of the swamp, metal detection expert Gary Drayton joins Rick Lagina and Craig Tester to sweep the stone pathway, pulling a square ox shoe nail from between the cobblestones. The find confirms the road was once used by draft animals hauling heavy loads in the direction of the Money Pit. While Billy Gerhardt excavates further sections of the feature, Dr. Aaron Taylor… 16 Episode 16 Leather Bound In the swamp, Rick and Marty Lagina join archaeologists Dr. Aaron Taylor, Miriam Amirault, and Liz Michels as the team traces the stone pathway further into the uplands near the eastern border of the triangle-shaped swamp. With over 400 feet of cobblestone now exposed, surveyor Steve Guptill measures the newly uncovered section and confirms its elevation at 1.5 feet above sea level, perfectly… 17 Episode 17 Staking Their Claim Terry Deveau, former president of the New England Antiquities Research Association, visits the swamp to inspect the massive stone road uncovered along its eastern border. His assessment carries weight: the feature is two to three courses thick, approximately six feet wide, and built to a standard consistent with cart track widths used across Europe for centuries. The construction technology… 18 Episode 18 Cannon Fodder In the swamp, Rick Lagina, his nephew David Fornetti, archaeologist Miriam Amirault, and heavy equipment operator Billy Gerhardt investigate whether the stone pathway is beginning to fork in two directions near the eastern border. As they clear overburden from the uphill section, Rick discovers puddled blue clay lodged among the cobblestones, a finding that immediately draws attention. The same… 19 Episode 19 A Loose Cannonball Near the eastern border of the swamp, archaeologists Aaron Taylor and Miriam Amirault continue excavating the stone pathway, which now appears to be branching in two directions, one heading toward the uplands and the other angling toward the Eye of the Swamp. Rick Lagina assists the effort, and the team discovers what Taylor describes as a possible cellar feature: courses of intentionally placed… 20 Episode 20 Fire in the Hole Rick Lagina gathers the team to report on a stone foundation unearthed near the swamp's northeastern border, adjacent to the stone pathway now estimated by Steve Guptill at 460 feet. The feature stands roughly two feet high with two clear right angles, buried beneath three feet of soil. Steve notes its resemblance to 1700s and 1800s foundations across Nova Scotia and its proximity to the property… 21 Episode 21 Off the Railing At Smith's Cove, Rick Lagina, Steve Guptill, Terry Matheson, and Charles Barkhouse oversee the team's effort to drill into targets identified on the Barringer survey, a military-grade VLF scan commissioned by Dan Blankenship and David Tobias in 1988. Borehole NF-1, targeting a nonferrous deposit between 80 and 120 feet, encounters dense clay at 79 feet before transitioning into crumbly limestone… 22 Episode 22 Be There or T-square Rick Lagina calls Marty with news of the possible ship's railing recovered from ten feet below sea level in the swamp. The team returns to expand the excavation, but overnight rain has turned the site into a nightmare of recirculating water and collapsing mud. Billy Gerhardt confirms wood on the bottom and pulls up a large timber, yet each attempt to dig deeper destabilizes the walls further.… 23 Episode 23 Old Wharf's Tale Along the stone pathway near the northeastern border of the swamp, Rick Lagina, Dr. Aaron Taylor, archaeologist Miriam Amirault, and Billy Gerhardt continue excavating as Gary Drayton and David Fornetti sweep the area with metal detectors. The team recovers annular ware pottery that Aaron dates to the early 1750s, along with badly burned stoneware fragments from the mid-1700s, both pre-dating the… 24 Episode 24 Silver Lining With the final week of the season underway, Rick Lagina, Steve Guptill, and geologist Terry Matheson direct the drill rig to borehole C-11.5, positioned north of the OC-1 caisson in an effort to establish a second intersection point with the 1706 wooden tunnel structure the team has been tracking across the Money Pit area. At 68 feet, the core returns possible backfill with traces of burnt… 25 Episode 25 The Silver Spooner Following the detection of silver in Money Pit water samples, Dr. Ian Spooner and Alex Lagina collect sediment cores from borehole C-1, hoping to pinpoint where the metals originate. Along the cobblestone pathway near the northeastern border of the swamp, Rick Lagina and Charles Barkhouse work with archaeologists Dr. Aaron Taylor and Miriam Amirault, heavy equipment operator Billy Gerhardt, and…
