[narrator] Tonight on The Curse of Oak Island...

-I've got a signal! -Ah-ha!

What have we got here?

I recognized this seal.

So, it could date to the 1300s.

That large boulder looks intriguing.

[Fiona] We've uncovered a big void right there.

[Rick] What is underneath that boulder?

We put cameras in BN-13.5.

[Bob B.] What we found suggests

-human origin. -[Jack] It really seems like

-it's a depositor. -Wow.

[narrator] There is an island in the North Atlantic

where people have been looking for

an incredible treasure for more than 200 years.

So far, they have found a stone slab

with strange symbols carved into it,

man-made workings that date to medieval times,

and a lead cross whose origin may be connected

to the Knights Templar.

To date, six men have died

trying to solve the mystery.

And according to legend, one more will have to die

before the treasure can be found.

♪ ♪

[Terry] This is the critical intersection

-right here, guys. -[Charles] Yeah.

What we should see beneath the Peacock is loose material.

Our targets are the possible void at 148 feet,

-and then the solution channel below that. -Right.

[narrator] A new day on Oak Island

brings fresh hope for Rick and Marty Lagina

that their team is closing in on the answers

to a 231-year-old treasure mystery.

[Steve] But really the end goal

is to get down in the solution channel and see

if there's a potential treasure there.

But I also believe that we're close to a chamber here.

Right.

[narrator] In a location

of the Money Pit area known as the Peacock,

the team is drilling borehole DN-13

just a few feet northwest of borehole BN-13.5.

[Adam M.] Whoa. Whoa, whoa, whoa.

[narrator] It was there that, one week ago,

the drill entered a possible man-made cavern

some 150 feet deep, which sets

more than 20 feet above the solution channel.

You can make out almost a wall or something there.

When you move away from it,

we kind of go more into an opening here.

[narrator] After inserting a camera,

evidence was revealed of a possible artificial wall...

-Show me the money. -[narrator] ...and a potential

-opening to a larger cavity. - We've got an opening.

[narrator] This made them wonder

if an offset treasure chamber connected

to the original Money Pit has been discovered.

Now, while the team waits to view enhanced video images

of the mysterious void,

they hope to drill into the larger nearby cavity

and confirm if it indeed is a man-made chamber.

[Terry] Oh, look.

Yeah, something's going on over there.

[Charles] Yeah. The rods fell.

They just dropped.

[Terry] That's really soft, man.

Adam!

[Charles] Here he comes.

[Terry] Hey, Adam.

-How's it going? -[Adam M.] Good.

Did something happen?

Uh, the rods fell about 16 feet.

-Really? -From 128.

-Wow. -Wow. That's really interesting.

-Thanks a lot, Adam. -All right.

That means somewhere between 118 and 128,

-we went into the soft area. -Right.

-Yeah. All the way to 144. -Yeah. Wow.

So, the core of the Peacock,

I've always believed, is going to be a structure.

Because of the loose soil, when we see

those rods drop, that tells us

maybe we're close to seeing the structure

that we all hoped we're going to encounter.

We're going to track that down into the solution channel.

You know, there's plenty of places down there

for a treasure to hide.

No question.

-We'll move on to the more interesting levels. -Yeah.

[narrator] As the core drilling pushes deeper

in the Money Pit area...

[Peter] That mound's getting higher and higher.

[Gary] Tell me about it.

[narrator] ...Rick Lagina

and other members of the team

continue investigating

the southwest corner of the triangle-shaped swamp.

After this, I feel like we only have one little section

-left behind us. -Yeah.

[narrator] In recent weeks,

the team has been uncovering a mysterious stone

road-like feature

that may be connected to a similar structure

that was found several yards to the north earlier this year.

Curiously, eight-sided wooden survey stakes were found

lining both of these features,

and the team also recovered old ox shoes,

suggesting the roads may have been used

to move heavy cargo into the swamp.

-Get in there. -[Gary] Okay.

[Rick] The southwest corner is almost done.

What we did learn is

we have a possible path or a road to follow.

And the hope is that there'll be some artifacts

that can be dated.

And then, maybe we can figure out

who made these features and why.

You ready for me to go in, Billy?

[Billy] Yes. Take the bottom there,

-Gary, maybe. -[Gary] Yup.

[rhythmic, mechanical beeping]

-It's getting quiet. -It is.

We hadn't had a hit in a while now.

[Billy] This might be the end of the line

for this area, I think.

[Gary] Yeah, I think you're right, Billy.

-And we hammered it. -[Peter] Everywhere we turn

in the swamp, we're finding stakes,

and that must mean something.

-[Rick] Yup. Has to. -[Peter] And my question is,

where are we going next? Because I know that there are

-other areas of interest. -[Gary] Yeah.

Who are you, and what did you do with Peter Fornetti?

Hey, the swamp is looking like a beach right now.

Let's get back into it.

[Rick laughs]

[Rick] You have three data points that

seemingly line up.

An unknown road/path,

ox shoes,

then you have the stakes.

And who knows what else is after that?

If there is a road, where does it go?

Right now, Steve has projected it to go towards

the north end of the bog.

So, now it gives us some insight as to where to go next.

And that's every bit as important as an artifact.

-Yeah. -[Rick] We've got to get back

to do some homework. We need to talk to Tom Nolan

about where to go next.

So, I say we head back.

-[Peter] Yeah. All right. -[Gary] Thanks, Billy.

[Gary and Peter] Thanks, Billy.

-[Rick] See you. -[Gary] See you, mate.

[narrator] As the team works on new plans

for digging in the swamp...

...later that day...

[Rick] I'm always grateful to come into the lab.

I think we learn so many things here.

And I'm impressed by these two finds from Lot 8.

[narrator] ...in the Oak Island lab,

Rick and members of the team

join Laird Niven and Emma Culligan

to hear a scientific report on a possible iron knife handle

and a lead bag seal that were found on Lot 8 one week ago.

The iron is kind of more of the mysterious piece,

so we'll start there.

And you can see that wood-like grain structure on it,

so, it is hand-forged.

But what is interesting is the shape of it.

So, it came in as a possible knife handle,

and it does have some features of it being, like,

the scale of a knife handle.

But it could have also been used as a multi-tool.

[Rick] But why

the round hole at the base and the square hole above?

[Emily] So this could have been used as a fastener

to hold something in place, a little pivot point.

But this section right here, I can find components

that are similar to other tools, but nothing like this.

-Okay. -[Emma] And the composition

is clean, so, it's post-medieval,

pre mid-1800s.

So, it does fit within the 1700s.

-Yup. -[Rick] It's very peculiar.

You know, it's possible

Carmen might have an idea as to what that represents.

-Yeah. -But the next item...

what does it tell us?

It's a bag seal.

[narrator] Dating back to as early as the 13th century,

lead bag seals were fasteners used to contain large quantities

of goods in heavy cloth packages.

I recognized an element of it right away, which was a...

I found an existing example of... of this seal.

And that is the only example we could find.

So this is the city seal of Leeds, in England.

So...

What a macabre design.

I know. It's so grim.

[Laird] So, this would have been a seal

-on a finished bale of fabric. -[Doug] Hmm.

So, that implies that it arrived on the island as a bale,

and that was taken off on Lot 8.

Wow.

Leeds in the 16th, 17th and 18th century was, like,

the wool manufacturing place in England.

And basically, Britain was built around wool.

-Oh, really? -Yeah.

That begs the question, what time period?

The Leeds wool industry goes back to the 1300s.

So, it could date earlier.

[Laird] The Leeds wool industry goes back to the 1300s.

Wow.

[narrator] In the Oak Island lab,

Laird has just confirmed

that the lead bag seal found on Lot 8 originated in England,

and could be as much as 700 years old.

When you say "bale," I picture something

-of great quantity, though? -[Laird] Let's say,

-the size of this, probably. -That much?

-So, big. Yeah. -That's a--

-Like a hay bale. -Yeah.

Isn't that a lot of fabric for a singular household?

That's the problem.

A singular household, you're going to those people

and buying your clothes.

[Doug] Why on the island?

-Here on the island, there were limited families. -[Laird] Yeah.

Bag seals are not uncommon in North America,

but they're usually associated with trade.

Like, a fort, you're finding a lot of these.

Because you're making uniforms, but you're also trading cloth.

This is our third bale seal.

Now we have three from different areas.

So, why is it there?

[narrator] Previously,

the team found a lead bag seal on Lot 5

and another on Lot 32,

just yards from the possible stone road

that was recently uncovered

in the southwest corner of the swamp.

Astonishingly, that bag seal was scientifically matched

to the 14th-century lead cross, which is believed

to be connected to the Knights Templar.

There's enough going on on Lot 8 that

I'd like to look closer, to take a good look

-at what's out there. -[Katya] Yeah.

[Laird] Could be something else that we're not aware of.

So, to that end, I think we need to get back out there.

-We have to get to work. -Yes.

You have to find things, and I will help you dig.

-That sounds like a plan. -That's a plan. That is a plan.

-All right. Thank you. -[overlapping chatter]

[Katya] Thanks, guys.

[narrator] The next day,

while drilling continues in the Money Pit area...

[Rick] You are of firm belief that

there are answers to the Oak Island mystery

-that reside within the bog. -How can you deny it?

No matter how you look at it,

somebody did an immense amount of work in that bog.

[narrator] ...Rick meets

with fellow Oak Island landowner Tom Nolan

and other members of the team in the research center

to plan their next dig in the swamp.

[Rick] I think the north end of the bog,

in terms of the size

and the amount of finds in a very confined space,

was quite exciting and incredibly interesting

and incredibly confusing.

The amount of stakes that we found,

all of uniform size,

uniform strikes in terms

of making the sharpened end, eight strokes.

And when you look at it,

as they're plotted, it's meaningful.

[Tom] Oh, really meaningful.

Somebody was trying to leave a path.

-Mm-hmm. -Mm-hmm. -Yup.

[narrator] Before uncovering the stone features

in the western and southwestern areas

of the swamp this year,

working with Tom on his property in the northern region,

the team previously discovered very similar stone structures

and several eight-sided survey stakes,

leading to an empty, vault-like structure.

Yeah. The so-called vault was captivating in and of itself.

I mean, we've found paths, roads,

but that vault was quite singular and unique.

Yeah.

[narrator] Now, Rick and Tom

want to know if all of the stone structures

they've uncovered across the swamp are connected,

and if other vaults

that still contain something valuable are waiting

to be found.

The vault-- to me, it was a hiding place.

It's in the perfect place to hide,

and in the most vegetation and stuff where people probably

-aren't gonna go looking. -Absolutely.

[Rick] If you are safeguarding something,

if you have something really important,

-you're not going to put all your eggs in one basket. -Right.

And you're going to have, you know, one, two, three, more.

-My hope is that there is a backup vault. -[Tom] Yup.

We're ready to put the bucket in the ground

-and see what's under it. -Well...

there's no time like the present, right?

-Yeah. Let's do it. -So, I say we get out there.

[Tom] Let's go.

[narrator] Following the meeting in the research center...

[Tom] I think we should start here,

take this apart, and then, once we get across that,

-just keep going to the other part of the bog. -Yup.

[narrator] ...the team begins searching for new clues

in the northern region of the swamp.

Gary, it's gonna be up to you

to find whatever artifacts are here.

-If they're here, we're going to find it. -[Rick] Okey doke.

[beeping]

[Marty] You know, the swamp has been enigmatic because

virtually every time we dig in there, we find something.

And not just something. We find things

that you wouldn't suspect would be in a swamp.

We find things that could very well be related

to the, uh, mystery of what happened here.

[Rick] We're close to the line where you found all the stakes.

[Tom] Yeah.

Is that-- Right there's your stake, right there.

[Rick] Probably right there.

Ah-ha!

[Rick] Probably right there.

But is it eight-sided?

Hmm. Two, three, four,

five, six, seven.

-There. -There's one there.

-And there's the start. -Yup.

-[Tom] There's your eight sides. -Wow.

They drilled that down deep for some reason.

[Gary] That's got to be really, really old.

[Rick] Last year, these eight-sided stakes

led us to a vault.

The stakes are a puzzle unto themselves.

There's every belief that as the stakes continue

to be found, at some point,

we will have an explanation as to why.

Yeah, that's where it was, right there.

Well, we're going to have to get Steve out to pin it

right now, before we move it.

Unless you can dig around it, Al?

Dig on this side and that side?

Maybe they can help explain the structures

that have already been found.

-Hey, guys. -[Tom] Hey, Steve.

What do we got?

-[Rick] You're standing on it. -I'm literally standing on it.

You're literally standing on it, and that's...

That's where it was. The hole is right there.

-Okay. The hole is what we want. -[Rick] Yup.

And like everything else,

we're a foot and a half above sea level.

And actually, most stakes that we have found

in the swamp have been a foot and a half above sea level.

They've been very consistent, which to me means

a lot of them were probably done in the same time period.

And that would be pretty interesting.

Yeah.

So, anyway, we'll keep going.

-Thanks, Steve. Appreciate it. -Thanks, guys.

[Rick] These stakes almost certainly represents

that a group of individuals did the work.

Implying a reason, implying planning.

Maybe it is connected to the vault that we've discovered.

-[beep] -I've got a signal!

[Rick] And I'm hoping that there are clues that will lead us to

new discoveries.

I've got a good signal in that last pile,

wherever the last pile came from.

Would have been on the bottom.

He was scraping bottom with that last bucket.

-So, it's... It was down there. -[Gary] That's excellent.

-That's where we'd find the older artifacts. -[Tom] Yeah.

Let me see if I can pinpoint it first.

[beeping]

[Gary] What do we got here?

-[Gary] What do we got here? -What is that?

[narrator] In the northern region of the swamp,

Gary has just found an intriguing artifact.

You know what that is?

That's like a sneck, a latch

off a gate or a door.

It would be inside an opening, and you'd put your thumb on it,

and you'd open the gate.

In England, we'd call it a gate sneck.

It's more than likely hand-forged.

This...

looks really, really old.

[narrator] A possible gate latch?

Found in the northern section of the swamp?

It's a great thought.

Your thumb fits in there perfectly.

-The latch springs up. -Yeah.

[narrator] Because these fixtures have been in use

as far back as the 13th century,

just how old might this artifact be?

And could it be related to a structure

that might be buried in this area?

Well, it's a great sign.

An old piece of iron came from the bottom of the dig.

-Yeah. That was down deep. -Mm.

I'll put it in the bag?

-Yeah. That's a good find. -Yup.

[Gary] Okay. Let her rip, Al.

-What have you found, Tom? -Piece of pottery.

But it's, uh... it's green.

Green and blue. You don't usually see that color.

[Gary] No.

-That decoration is unique, too. -[Tom] Yeah.

[Gary] This area

with the green and the blue glazed pottery,

it could match another area

where the archeologists have found it.

I know it's been found before.

-Yeah? -I think some green and blue

came off the Lot 26 wall, as well,

when the archeologists were investigating,

taking the wall apart.

We have to find artifacts.

-Okay. Get on that. -[laughs]

[narrator] In 2022,

the team investigated a rock wall on Lot 26

because it was much larger and wider

than a number of others on the island

that are known to have been built

by farmers in the 19th century.

Incredibly, in addition to pottery,

charcoal was found in the wall that, when carbon-dated,

suggested it could be over 500 years old.

And when Portuguese researcher

Francisco Nogueira inspected it, he made

a fascinating observation.

No way.

[narrator] Could this piece of pottery be the same kind

that was found in the wall on Lot 26?

If so, is it possible that the wall is somehow related

to the manmade workings uncovered in the swamp?

[Rick] We have a suggestion

by experts that some of the activities conducted here

on the island can be associated with the Portuguese.

The stone road, the swamp has Portuguese influence.

The stone wall has influences.

The Pitblado Portuguese Templar coin that was possibly found

in the Money Pit.

It's a worthy consideration

that they all may have a connection to the mystery.

[Gary] We'll get these finds back to the lab.

I mean, we've had a great start to the dig in this area.

-Yup. -[Rick] It shows

-there's things to be found here, right? -[Gary] Yeah.

-[Tom] I agree. -[Rick] We just have to keep

-plugging away. -Yeah.

All right, Al, we'll take her down quite a bit more here.

[Alan A.] Perfect. No problem.

[narrator] Later that day...

[Laird] So, this is what I wanted to show you.

-We've got this large boulder... -[Rick] Yup.

...which is uncommon.

[narrator] ...after looking around the area on Lot 8,

where the lead bag seal was found,

Laird has made a potentially important discovery.

[Laird] We're not seeing them around here a lot, that size.

But then I started seeing

the number of stones that are around it.

-Perhaps filling in something. -Mm-hmm.

Even the berm over there, that could indicate digging.

It looks like someone was filling in a pit.

And actually, if you look again,

the rocks seem to go further off to the east.

-Mm-hmm. -The more I look, the more I see.

Yup.

[narrator] Could Laird be correct

that someone deliberately filled in a pit

around this massive boulder with soil and smaller rocks?

But if so, who did it? And for what purpose?

You know, it appears as though there is a ring of stones

-around the boulder. -Mm-hmm. Yeah.

It's not unusual to find a boulder on Oak Island,

but even more interesting was the

ground-level rock feature around it.

My immediate thought was that this was

a possible filled-in foundation that we're not aware of.

I don't know the relationship between that large boulder

-and this stone formation just yet. -Mm-hmm.

But I think it's definitely worth exploring.

It's interesting. There's no doubt about it.

[Laird] Yeah. Lot 8 has intrigued me.

-But then you and Katya recently found the bag seal? -Correct.

Which is another really intriguing artifact.

I know its function, but why is it here?

-[Rick laughs] -And then,

we find this huge boulder and these rocks.

It does make me think

that we need to really analyze it.

It's certainly unique,

and, like you said, you can see

the raised areas everywhere, right?

-Yeah. Yeah. -Here, here. There.

-This would have been quite an effort by someone... -Mm-hmm.

...if this really is a hand-built construction.

[Laird] Yeah. So, I think what we'll do, we're going to

-clear it off, clear that whole area off... -Mm-hmm.

...to get a good idea of what it looks like.

And then, hopefully, taking a section from it.

Sure.

This may provide a very unique opportunity

to try to understand, not only this lot, but the entire island.

-[chuckles] -You know, not every stone

-on this island means something. -Yes.

-But some of them do. -Do. Yup.

-And this may be one of those times. -Yeah.

[Rick] If it's been filled in,

there might be something hidden that would break the story open.

At this point,

the archaeologists need to get to work.

This is surely worth investigating.

You've laid out a very proper approach.

I applaud you for, again, being observant.

Um, I-I think if there's any way we can help,

we all would invest some time here.

You're leading me into the dark side

because I'm really intrigued by that stone.

It does make me think that there's a lot more out there.

-Here. Welcome to the dark side. -[laughs]

-[Rick] We've got work to do. Let's go. -[Laird] All right.

[narrator] At the start of a new day on Oak Island...

-We got lots of work to do, guys. -Yeah.

[narrator] ...Laird and members of the archeology team

investigate the possible man-made boulder

and rock feature on Lot 8.

There's a lot of rocks in here, Laird.

-Yup. -I've never seen this many rocks

-underneath the topsoil layer. -[Laird] Yeah.

Kind of looks like there was a cut,

and at some point, it got filled back in.

I've got the edge here, I think.

-[Fiona] Oh. -You may be coming to an edge.

Well, I am getting to the different soil here.

But you should be coming to what we think may be the redeposited.

Well, there's a nice big lump right behind Ethan.

-You're right. It's mounded. -[Laird] Yeah.

That's a good sign. There was digging,

for whatever reason, and then it got filled in.

And then you got this huge rock in the middle.

Like, I find that strange, as well.

I think we still have to at least define the edges

as we go, all the way around

-the, uh... the boulder. -Yeah. Okay, good.

Okay, so let's... let's see how far back this goes.

[Laird] To me, this site is one

of the strangest sites I've been on.

It doesn't make any sense

that someone would come and excavate

and then fill it back full of rocks.

[Fiona] It's brutal work.

[Laird] So, I find it very unusual, and I can't wait

to get the excavation deeper, and, hopefully,

answer some of these questions.

[Fiona] Hey, look at this.

A piece of wood.

Does that look like that top's been cut before?

I didn't do that.

[Laird] Sure does.

Doesn't look like it got snapped off.

[Fiona] No. That's what I'm thinking.

I think that if that was cut,

then that could've been cut

by whoever created whatever this is.

-That's... -[Laird] Yeah. I could see that.

[Fiona] I mean, that was deep. That was... that was underneath

all these roots that I've been pulling up.

-So, that is not something that was on the surface. -Okay.

If this was cut, that would have been years ago.

-Many years ago. -That's what I'm thinking.

The sticks that had cut marks on them,

that's another evidence

of cultural activity happening there.

Okay. We better keep our eye out for stuff like that.

[Laird] Okay. Cool.

[narrator] As the investigation continues on Lot 8...

[loud mechanical whirring]

[Adam M.] Oh, yeah.

Pull!

[narrator] ...in the Money Pit area...

[Steve] Looks like you guys are in bedrock.

If he's driving it over,

that would be his 20 feet through the solution channel.

[Charles] I guess we missed

-the void at 148 feet. -Yeah.

[narrator] ...after finding no new evidence

of the void that was discovered

nearly 150 feet deep one week ago,

the drilling operation in borehole DN-13

has now reached

the solution channel.

[Adam M.] Bottom's 208, rock is 204.

[Charles] Bottom's 208. Rock is 204. Got it.

At least we have intercepted the bottom

of the solution channel in this hole.

There we go. [groans]

She's a full-on anaconda, ladies and gentlemen.

Here we go. Cut her up.

DN-13,

this is the last gasp, I think, since we're on bedrock.

Let's see what we got here in front of us.

This up here actually is a little bit loose.

Actually, it got a little loose between, uh, 184 and 188, so...

-Yeah. -...I think we're ready for the pin-pointer.

Okay.

[Terry] This is the more promising

-upper portion, which is a bit slushy. -Yup.

It's clear, gentlemen.

Okay. Thank you, Charles.

Well, it's not the ending we hoped for, for DN-13.

[Steve] We've had all kinds of success

in this area with metals being in all the water testing.

-So, we'll take a soil sample back to the lab. -Yeah.

And maybe, just maybe, there will be

some hope with this borehole yet.

[Steve] I can't believe we missed an open void

at 150-ish feet.

If we can prove that there's metals in the soils here,

and that's through testing through Dr. Spooner

and testing in the lab with Emma,

we can prove that this is potentially

still a treasure location.

We'll move on, and we'll go back to the heart of the Peacock.

And let's try to get back in that void.

Very good. I'm in full agreement with that, Steve.

[Charles] Okay, fair enough.

[narrator] Later that afternoon...

-[Peter] Hey, guys. -[Jack] Hey, guys.

[Rick] Hey, guys.

-Hello. -Hey.

[narrator] ...in the war room,

Rick, Marty and members of the team meet

with video enhancement expert Bob Brown

from Prohawk Technology Group.

[Rick] The reason for this meeting is

in BN-13.5, we put camera down and sonar.

It showed a void.

Uh, the thought was to give it to Prohawk

to enhance the data that we've given them, so,

having said that, Bob, welcome to the war room.

Appreciate it. Thank you so much.

Here's a little of the footage.

[narrator] Prohawk Technology Group

has worked with the team several times in the past,

using their proprietary software

to clarify underwater video images

collected from deep in the Money Pit area.

[Bob B.] This one was really interesting.

Really, there were

distinct things

that we kind of noticed in the imagery.

So, we found this to be quite interesting.

You can see here, this cluster of

stake-like pointed objects, right?

It just looked arranged, and the shapes,

the tapering, the alignment appears deliberate.

And would suggest planked stakes,

something, you know, of human origin...

...rather than the natural environment.

[Tom] You know, I can see

a layering effect in there, that it does look man-made.

Mm-hmm.

We are all intrigued.

It would defy logic

that those could be represented geologically.

It's different-- unexplainable, really.

I mean, you guys are dealing

with cutting-edge technology here.

Yeah.

[Rick] I still need to be convinced, but it makes

the Peacock area that much more interesting.

And I think that's what we have to go off of.

Then there were definitely these distinct, square

geometry patterns throughout many portions of the video.

The edges, the uniformity of it,

um, and you take it all together,

and it really begins to add up

that there's something that's not organic.

Another area we found,

there was a bright, reflective rectangle.

Right? It's got sharp edges. It's highly reflective.

So, that would lead us to believe that there's some type

of metallic or polished quality

that's causing the reflection.

[narrator] A possible rectangular metal object?

Has the team indeed found a man-made chamber

some 150 feet underground in the Peacock?

Well, yeah. I mean, this is really keenly interesting.

[narrator] If so, could it contain the source

of the precious metals that have been detected

in water deep in the Money Pit area?

[Marty] Bob, if you had to say how likely these,

at least one of these is a man-made object,

what would you say?

I'd put it over 90%.

Wow.

[Marty] Bob, if you had to say how likely

at least one of these is a man-made object,

what would you say?

I'd put it over 90%.

[Marty] Wow.

[narrator] In the Oak Island war room, Rick, Marty, Craig

and members of the team

are viewing enhanced video of a potentially man-made cavern

some 150 feet deep in the Money Pit area.

[Bob B.] It really came down to geometry, precision,

consistency, the arrangements, the materials.

They strongly suggested man-made origins.

It's just

really compelling evidence.

[Alex] An open void is highly unlikely to be natural

for the depth that we're looking at, right?

-Correct. -[Marty] Is there any geologic explanation for this?

'Cause I can't really think of one.

[Terry] I would say, this is my working premise,

is that the Peacock is the wash-out around a structure.

And perhaps we're seeing into that structure

from our actual borehole.

I mean, it's deeper than any searchers.

And if there are weird, anomalous features

that Prohawk's picking up, it really seems like

-it's a depositor. -[Marty] Yeah.

[Rick] I am taken aback by the number of things

being represented in such a small, confined space.

He saw several items that represented very linear,

90-degree angles

that we've been told many, many times

that that doesn't happen in nature.

And I have no explanation for this reflective image.

I can only insinuate that it has something

to do with metals being underground.

Perhaps there is a man-made reason

for those highly unconsolidated soils in the Peacock.

This would strongly suggest

that the offset chamber is a valid explanation.

So, this area is quite compelling.

[Marty] Bob, I mean, does this look like a jumble of stuff

that could've collapsed?

It-- It could have collapsed. Yes.

[Marty] Okay. We should jump

up and down about this data, right, guys?

I mean, we're seeing man-made objects--

or strong indications of it-- in an area where

we haven't had any indication of any searchers.

This is the kind of thing that we set out to find.

You know, for sure, we have to explore this further,

but that's pretty dramatic.

The Peacock still has very elevated amounts of silver

and some other metals in it, so,

here's the point.

The source of these metals in the water is still there

and hasn't been found.

But maybe we just found it.

Bob, we hope you got a bullseye for us.

Yeah, I hope so.

Thank you very much. Appreciate it.

[Bob B.] You bet.

Our pleasure and happy hunting, guys.

-[Alex] Thanks, Bob. -[Peter] Thank you.

[narrator] As the meeting concludes in the war room...

[Fiona] I'm just looking at these rocks here.

What about if you started from the rock in there, out?

Yeah.

[narrator] ...archeologist Fiona Steele

and members of the team

investigate the boulder feature on Lot 8.

[Fiona] I'm really interested in what's happening down there.

There's definitely evidence of the stones

being deliberately placed around the outside

and underneath this huge, erratic boulder.

Such a big rock could be something

that was used for a marker.

It could be something that...

that you'd want to hide things under.

So, it's just so out of the ordinary,

that we need a little bit more evidence

before we can make that full determination.

-[Isabelle] Fiona? -Yeah?

I found a piece of wood.

I don't know if it's cut, though.

-Look at that bottom. -Yeah.

[Fiona] That does not look like it's broken.

I would say that's cut.

[Isabelle] It was wedged right in there,

in between the rocks.

These are the type of things we need to look out for.

It could tell us a lot about the age of this feature.

[Isabelle] Yeah.

Oh, it-it goes down.

Can you get your arm right in there? Yes, you can.

-Whoa. You're going deep. -[Isabelle] Yeah. It looks

like a void down there.

You've got a big void down there.

And you would not expect to see a big void like that

-right there. -No.

Not with the size of the rock and how loose the soil was.

[Fiona] Yeah. I would agree.

This large boulder is getting more

and more interesting, because as we're going,

we're seeing more and more spaces

that are underneath the rock.

And this really shouldn't be the case.

That really speaks to what they were doing here.

-Yeah. -[Fiona] So, it's very evident

that man has been involved

with this boulder to some degree.

It's just a matter of why they were there.

Or whether they were doing something

to hide something in that area.

Well, that's a good indication of possible disturbance.

But I really think that Rick might be very interested

-in this. -Yeah.

[Fiona] This is really cool.

[Isabelle] Definitely.

♪ ♪

Well, looks a bit different.

Hi. Yeah, we've been working hard.

-[Rick] I see that. -We've uncovered

a-a fair bit more of it.

You should see what we just discovered.

[narrator] Rick and Scott arrive on Lot 8

after being alerted that a mysterious void

has been found beneath the massive boulder.

We're seeing voids like that around other areas

-around the large rock as well. -[Rick] Yeah, I see that.

-Yeah. -[Isabelle] It looked like it was going down quite far

because the soil was falling in as I was e-excavating it.

-Mm-hmm. -And it goes pretty far down.

[Rick] Yep.

It looked like it was at least three feet that goes down.

So, that's got our curiosity piqued--

that it would be going that deep.

Y-You wouldn't expect to see that.

I find that...

strange.

See how this almost seems placed?

-[Fiona] Jammed up? -This one almost seems placed.

[Rick] That's not a toss-in.

Look at that.

That is almost fitted.

As is that, as is that.

[Scott] Yeah. Like a wedge.

-[Rick] It is peculiar. -Yeah.

We've not found any other feature like this

other than maybe the stone structures on, uh, Lot 5.

-Mm-hmm. -Mm-hmm.

[Rick] Looking at the boulder more closely,

I was significantly struck

by the placement of smaller stones around it.

They are equally spaced.

They are artfully applied, if you will.

But there is a stone, then a space,

then a stone, then a space.

Mother Nature wouldn't do that.

So, human beings were involved

in doing some work in this area,

specifically directed to this stone.

This may have been completely unknown to previous searchers.

It's exciting.

We need to find out what is underneath that boulder.

Boy, there's intention there, I think.

I-I can't imagine...

how you could explain that

other than they were placed there.

I agree with you 100%.

[Rick] And now you have another reason to be inquisitive.

"Why is the void?

-That should be filled up." -[Scott] I would think so.

[Scott] I mean, if you wanted to hide something there,

you move something like this in place, y-you position it.

I mean, it's a unique stone, just look at it.

This could be a great marker stone.

But I'm more excited about what could be under it.

We're gonna find out once we move the rocks.

[Rick] Uh, look, the three of you

have done an exemplary job here, and this is singularly unique,

-at least as of right now. -Yeah.

[Fiona] Yeah, we still have a lot more work to do,

but, uh, we-we're feeling pretty good about...

-[Rick] -...how far we've come so far.

-Yeah. -[Scott] Well,

a feature like this, the one line that comes to my mind

-is "leave no stone unturned." -[laughter]

[Fiona] Touché. We're with you on that.

[narrator] Patience and persistence

have taught Rick, Marty and the team a priceless lesson:

the ultimate truth behind the Oak Island mystery

may be hiding in plain sight

anywhere across these 140 acres.

But as they uncover more clues

under man-made features near the surface,

in a muddy, brackish swamp,

and deep in the Money Pit area...

...will it lead to a vault that people have been seeking

for 231 years?

Or is the truth

that Oak Island contains more buried treasure

than anyone ever imagined?

Next time on The Curse of Oak Island...

[Charles] We're in a sweet area right here.

[Ian] There's metals in the water.

-High metals. -We're looking for the one thing.

This could be where it's coming from.

-Yeah. -Exactly.

-[Rick] What are you seeing, Peter? -Definitely a void

that goes on for a long ways.

[Rick] We're gonna get to the bottom of this.

There's a heck of a lot of bricks up here.

[Craig] Maybe it'll lead to a vault.

Wow.
