Plot Summary

The episode starts at Borehole 10-X, wherein the guys of Oak Island tourism Inc. Are in the process of airlifting water native the room at the bottom that the shaft in the hope the they might carry up evidence of a human presence in the chamber prior to 1795. Throughout this process, the slurry indigenous the room at the bottom the 10-X is pumped up to the surface and deposited in a sediment tank. After to run for some time, the airlift abruptly stops working. The an equipment operators doubt that part debris might be lodged in the upcoming hose and also make part adjustments accordingly. In no time, the airlift is running smoothly again.

After to run the airlift for part time, the team decides that if there was anything of interest inside the room at the bottom of 10-X, it need to now be in the sediment tank ~ above the surface. Once the water from the tank is drained, stack Lagina, Charles Barkhouse, Jack Begley, and also former Oak Island resides Dan Henskee shovel the sediment right into the bucket that a loader. If shoveling, the sweetheart hunters find several piece of material they are unable to immediately identify, in addition to a tiny bone. This items space bagged and collection aside because that future analysis.

Once every the 10-X sediment has been transferred to the loader bucket, that is revealed that Jack Begley will be in fee of sifting v the debris. The next scene mirrors Begley and his stepfather Craig Tester sifting with the last of the 10-X debris, which they have actually spread out on a diamond mesh trough. Immediately, the pair discover a hand-sized chunk that milled wood bearing the point out of one old-fashioned hand saw lying among the sludge. Soon afterwards, Begley discover some timber slivers spanned with a black, viscous substance he speculates could be pitchblende (also recognized as uraninite, a radiation uranium ore which had previously been discovered on Oak Island by sweetheart hunters). The narrator then briefly explains how pitch (or resin, a blanket term provided to explain dark, viscous substances like tar, bitumen, asphalt, and also tree resin) has actually been supplied for millennia come caulk ships and waterproof wood containers.


Later that day, the Oak Island team meets in the war Room. There, Jack Begley presents his other treasure hunters with the items of interest he found while sifting v the debris lugged up from the room at the bottom the Borehole 10-X. First, Begley mirrors the team number of pieces of hand-sawn hardwood he uncovered. Upon gift prompted, Dan Blankenship proclaims that the timber is nothing like anything he, his boy Dave, or fellow treasure hunter Dan Henskee could have dropped right into 10-X while working in that in the 1970’s and ’80’s, speculating the the pieces are most likely “older 보다 .”

Next, Begley reflects the Oak Island team a grasp of old lumber slivers extended in a substance which the believes could be pitch or pitchblende. Again, Dan Blankenship is adamant the these items might not possibly have made their way into 10-X during his excavations in the ’70’s and also ’80’s.

The team decides to have actually the items indigenous 10-X carbon dated. In light of the brand-new evidence, Marty Lagina claims “there’s not fairly an ‘X’ in 10-X.” v that, the meeting is ended.

The adhering to day, the Oak Island crew gathers in ~ Smith’s Cove, where they hope to uncover proof of the legend box drains thought to be hidden there. V the assist of contractor Jeremy Frizzell and veteran Oak Island sweetheart hunter Dan Henskee, they begin to construct a small, temporary, 8-foot-high blow up cofferdam approximately a ar of Smith’s Cove i m sorry will allow them to dig deep into the area inside without having actually to content through the tide. Suddenly, the cofferdam inexplicably ruptures, rendering it useless. The narrator reveals the Frizzell, the contractor in fee of installing the cofferdam who has witnessed thousands of successful inflatable cofferdam installations in the past, has never seen an blow up cofferdam explode in this way. Stack Lagina do the efforts to reassure the contractor, speak “there have actually been multiple, multiple tools failures top top this island. Points that just should no go wrong walk wrong.” The narrator complies with up on this by explaining exactly how labourer Maynard Kaiser, on in march 26, 1897, fell to his death in an Oak Island pillar when the rope to which the bucket that rode in to be attached inexplicably slipped indigenous the hoist. He goes top top to define how Kaiser’s death unnerved countless of his other labourers, some of the more superstitious of who feared that some type of malevolent pressure guarding the Oak Island treasure was responsible for their co-worker’s untimely demise.

Following the setback, a crestfallen Jeremy Frizzell assures the Oak Island team the he will replace the cofferdam and also attempt to install it in numerous weeks. Craig Tester speak him “you may not be supplied to this, however we’re supplied to come this.” v that, the crew wraps up the operation.

Later, in the war Room, rick Lagina, Charles Barkhouse, and also Rick and Marty’s nephew Peter Fornetti meet with Oak Island researchers Doug Crowell and Paul Troutman, the latter being the kid of James Troutman, a man who worked alongside endowment hunter Robert Dunfield in the mid-late 1960’s. There, Troutman educates the endowment hunters that he has dug up numerous letters and documents in connection with to former U.S. Chairman Franklin Delano Roosevelt and the Oak Island sweetheart hunt. The narrator then defines how a young Franklin Roosevelt was among the financiers the the Old yellow Salvage and Wrecking Company, one Oak Island treasure hunting syndicate headed by engineer Harry L. Bowdoin which activate in 1909, and how Roosevelt, transparent his 12-year term as President that the United says (which extended the an excellent Depression and also World war II), maintained his attention in the Oak Island sweetheart hunt.

Franklin D. Roosevelt

Troutman reveals that one of the records he has carried to the war Room confirms the Roosevelt was a Freemason. Barkhouse responds by remarking that plenty of people involved in the Oak Island treasure hunt end the years, including treasure hunters Irwin Hamilton and also Gilbert Hedden, were also Freemasons. The narrator then briefly describes the concept that the Knights Templar buried sacred religious artifacts top top Oak Island following the suppression of their Order in 1307, and that their an enig rituals and ideals lived on in Scotland, wherein they were eventually reconstituted together Freemasonry.


At the end of the meeting, Troutman notifies Rick, Charles, Peter and also Doug the a wealth of info on Franklin Roosevelt’s Oak Island link is available in the archives of the FDR Presidential Library in Hyde Park, brand-new York. Troutman invites the treasure hunters to accompany him come the archives to inspect out these documents, and also the men heartily expropriate his invitation.

Later, stack Lagina and his nephew (Marty’s son) Alex carpool come the FDR Presidential Library. There, they accomplish with the library’s Public regimen Specialist Clifford Laube, who directs lock to whereby Paul Troutman is hunkered down, putting over archival material. Rick educates Troutman that he is interested in learning why Roosevelt maintained such an intense interest in the Oak Island treasure hunt throughout most of his adult life, and Troutman informs Rick that, if such information exists, it could likely be gleaned from Roosevelt’s “personal files”, which he has already assembled ~ above the table. Unfortunately, these documents contain a lining 17 million pages, only 10% the which have been scanned. Rick remarks, “it looks like we’ve got our work cut out for us,” and with that, he, Alex, and also Troutman begin pulling files.

In time, Troutman uncovers a letter handle to FDR stating that there were at the very least two treasure hunts on Oak Island in enhancement to Bowdoin’s in and around 1909. The narrator then describes how Franklin D. Roosevelt’s grandfather, Warren Delano, to be a shareholder that the Truro Company, Oak Island’s second major treasure-hunting syndicate which activate in the mid 19th Century.

Next, Troutman reflects Rick and also Alex a transcript indigenous an interview the Duncan Harris, a schoolmate and confidant that Franklin Roosevelt, conducted by biographer Joseph P. Lash. In it, Harris maintains that Roosevelt believed that Oak Island’s secret treasure had “the shed jewels the Louis XVI and also Marie Antoinette,” the last monarchs of France who were executed by guillotine throughout the French Revolution.


With that, the episode abruptly ends.



In this episode of The Curse the Oak Island, Jack Begley, if sifting through the sludge airlifted from the cavern at the bottom the Borehole 10-X, found several slivers of old lumber coated in a viscous black substance which the speculated might be pitch (tar), or possibly “pitchblende”. Interestingly, pitchblende- a radiation uranium ore- has actually been discovered in Borehole 10-X in the past.


In 1970, Dan Blankenship and David Tobias of Triton Alliance rental Golder Associates- a Toronto-based geophysical company- come drill ~ above Oak Island at spots prescribed by Blankenship, i beg your pardon he uncovered by dowsing. From among the countless holes lock drilled, Golder Associates brought up thin, low-carbon stole from a depth of 165 feet. This uncover prompted Triton Alliance to increase the drill hole right into a 230-foot-deep shaft, i m sorry is known today as Borehole 10-X.

While digging Borehole 10-X, Dan Blankenship unearthed spruce timber coated in a thick, black color substance in ~ a depth the 167 feet. Triton Alliance had actually the hardwood carbon dated, and were astonished to find out that the check results, incredibly, shown that the wood came indigenous the future, especially some time in the early on fourth millennium A.D.

In stimulate to recognize the factor for this bizarre check result, it helps to have actually a basic understanding of carbon dating. Carbon dating is a method of identify the period of an organic (once living) material by measuring its carbon 12/ carbon 14 ratio. Consistent carbon, or carbon 12, renders up 99% that of all the carbon in the universe, and is a secure molecule which go not decay over time. Carbon 14 (a.k.a. Radiocarbon), ~ above the various other hand, is a volatile, naturally-occurring, lot less typical carbon isotope v two additional neutrons (which is a fancy means of saying the carbon 14 is slightly heavier 보다 carbon 12, but has the same magnetic charge). Carbon 14 is radioactive, which method that the spontaneously emits radiation and also decays (i.e. Transforms into nitrogen 14) over time. When an organism dies, the carbon 14 present in it instantly starts to decay, while the quantity of carbon 12 in it stays constant. Since the carbon 12 / carbon 14 proportion in the atmosphere and also living biology is reasonably constant, and also since carbon 14 decays in ~ a relatively consistent rate, scientists have the right to determine the age of a sample of dead organic matter by measure its carbon 12/ carbon 14 ratio. Today, this is accomplished with mass spectrometers, tools which deserve to accurately determine isotopic ratios (i.e. The ratios between versions that the same element which differ only in weight, favor carbon 14 and also carbon 12) current in a sample through the usage of electromagnets. Back in 1970, however, scientists figured out the carbon 12 / carbon 14 ratio existing in organic material by using Geiger counters- devices which measure the radiation emitted by building material (which, in the instance of carbon dating, was the radiation emitted by disk carbon 14). The radiation emitted through the slivers of timber coated v thick black color goo, i m sorry Blankenship and also his crew uncovered in Borehole 10-X in ~ the 167-foot depth, to be off the charts (seemingly indicating that the sample contained method more carbon 14 보다 it chandelier to).

As that turned out, the black color goo that coated the hardwood slivers to be pitchblende, or uraninite, an extremely radioactive mineral ore include large amounts that uranium and smaller quantities of highly radioactive radium. Pitchblende is no endemic come Nova Scotia, but fairly to northern Saskatchewan, great Bear Lake in the Northwest Territories, and also parts the Germany, Czech Republic, Congo, Rwanda, southern Africa, Australia, the united States, and, significantly, Cornwall, England (several theories concerning the nature that Oak Island’s treasure involve Cornish miners). Prior to Polish chemist and physicist Marie Curie provided it to isolate radium in the the late 19th Century, pitchblende to be chiefly supplied to colour glass and also porcelain. According to part sources, that was additionally employed as a preservation agent because that timber.

Marie Curie, the scientist whose examine of pitchblende brought about her exploration of the facet radium.

FDR and also Oak Island

In 1909, engineer and also inventor Henry L. Bowdoin started an Oak Island treasure searching syndicate called the Old yellow Salvage and also Wrecking Company. One of the company’s shareholders to be a young law clerk from brand-new York City named Franklin Delano Roosevelt, that would later go on to come to be the 32nd chairman of the united States.

The Oak Island Mystery (1958, 1957), a book written by a lawyer closely linked with the Oak Island sweetheart hunt named R.V. Harris, posits the FDR an initial heard that the Oak Island an enig “from the civilization of Campobello Island, in the just of Fundy, where his mother had actually a summer residence.” In this episode that The Curse of Oak Island, however, the narrator briefly intimates the Franklin Roosevelt can have learned about Oak Island from his grandfather, Warren Delano Jr., a wealthy businessman associated with the British-Canton opium profession who invest in the Truro Company, Oak Island’s second treasure hunting syndicate, in 1849. Whatever the case, FDR preserved an intense interest in the Oak Island treasure hunt, regularly matching with Oak Island landowners, treasure Trove licence holders, and also treasure hunters until his death in 1945.
