Original subtitles

NARRATOR: Tonight, on The Curse of Oak Island...

STEVE: We're coming in to the cavity now.

-There's a linear feature right there. -ALEX: Whoa!

It looks like a hallway or a tunnel.

Wow.

MOYA: Helen, I think I found something.

That indicates marine activity.

Yeah, it's really interesting.

Do you have any idea what that is?

What?

ROGER: I tapped into a cavern

from the side of my shaft.

RICK: This could be an offset chamber.

Yeah.

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.

♪ ♪

STEVE: Look at the water coming in.

ROGER: Yeah, that's quite a bit.

MARTY: Here's the water.

NARRATOR: A new day has arrived on Oak Island

for brothers Rick and Marty Lagina

-and their team. -Where's that coming from, Roger?

Right now, it's coming from the walls,

so it's coming down between our tight lining.

-MARTY: Is that the bottom? -Yeah, and it's just referring

right back to the bottom.

NARRATOR: But unlike most

that begin with new search activities in the hopes

of solving a 228-year-old treasure mystery,

today, they must first contend with a sobering setback

in the Money Pit area.

ROGER: We were all talking about all this water.

Like, I know we had tons of rain and-and it sure didn't help.

We just found it excessive.

-Yeah, I would be concerned about it. -ROGER: Yeah.

NARRATOR: Following a recent torrential rainstorm,

which battered the southern region of Nova Scotia,

something that may not be related to Mother Nature,

triggered a constant flow of water

to enter the Garden Shaft at a depth of some 66 feet.

30 feet of water didn't fall in that area.

-No. -Only ten inches did.

-That's right. -Is that deep enough

to be the flood tunnel?

NARRATOR: Whether or not the source of the water

is related to one of the legendary flood tunnels

that have plagued searchers for more than two centuries,

it has halted the team's current operation

to deepen the Garden Shaft

beyond its current depth of 87 feet,

down to a target depth of nearly 100 feet.

It is there where the team hopes to breach

a mysterious seven-foot-high tunnel.

One that leads due west toward the Baby Blob,

an area where high-trace evidence of gold,

silver and other metals have been detected

between 80 and 120 feet underground.

MARTY: Last year, almost no water was coming into the shaft.

This year, it appears to be pouring in.

We have to figure out what's going on with the Garden Shaft.

Could this actually be the flood tunnel

that's causing our problems? I don't know.

That's what we're here to find out

because we could be that close to the treasure.

Are they pumping right now? They're pumping it out?

ROGER: Yeah, that's what they're doing right now.

They're lowering the pump and we're going to see

where the sediment's at.

So, we started drilling a bunch of holes in there.

Probe holes to see if there's, you know,

is there anything out there that we're not aware of?

And we did find some voids.

-Really? -Oh, yeah. For sure.

STEVE: So, it could be a flood tunnel. We don't know.

-Yeah. -MARTY: Well, I'll tell you what.

We can sit here and guess all day

where the water's coming from, but let's stop it.

Yeah. My biggest concern is stopping this water.

MARTY: Yeah.

You're going to do it today? The urethane?

ROGER: Uh, it won't be today.

What we're going to do right now is kind of define drill,

find out exactly where that void is going, where it is.

And then we're gonna probably look at

getting all these cavities filled,

hopefully stopping this water completely.

Okay.

NARRATOR: In an attempt to stop

the inflow of water,

representatives from Dumas Contracting Limited

will use the exploratory holes they have drilled

to fill the mysterious voids outside of the shaft

with multi-urethane,

an industrial-grade compound

that expands in order to seal off open spaces.

RICK: The goal is to extend the Garden Shaft

to the top of the previously unknown tunnel,

and with 700 gallons an hour coming in on that shaft,

there is no way that's going to happen.

This presents some difficult issues,

and they have to be resolved.

We cannot accomplish the goal unless

we stop the water from intruding into the shaft.

ROGER: So, once we seal all this

and everything is foamed up and solid,

then we get down there, we start digging again.

Our number one focus is get down in that shaft.

Good deal. Roger, look, I'll be keenly interested

to see how that turns out.

Oh, I'll keep you posted.

-Please do. -Absolutely.

MARTY: Okay. Carry on, Roger.

ROGER: Right on. Thanks, guys.

NARRATOR: As the team from Dumas

continues their work in the Garden Shaft...

LAIRD: That's a lot of water.

PETER: Yeah, we had a crazy amount of rain.

We had about nine inches in 12 hours.

Yep.

NARRATOR: ...on Lot 5,

located on the western side of the island...

LINDY: Hopefully,

once we get it pumped out, it'll start to dry up.

...Peter Fornetti, lead archaeologist Laird Niven

and other members of the team arrive

at the mysterious circular structure

near the shoreline to assess its condition

following the recent storm.

I think we'll be able to still work up here.

JAMIE: I hope so, yeah.

All right. So, let's take the tarp off.

Yeah. Works for me.

Let's do it.

NARRATOR: Although this feature

sits nearly a mile from the Money Pit area,

it has yielded a number of clues

suggesting that it may also be critical

to solving the Oak Island mystery.

JAMIE: There we go.

NARRATOR: After finding a lead barter token last year

near the outer rim, and which may be

directly connected to the 14th-century lead cross

that was found in 2017 at Smith's Cove...

FIONA: Okay. What is this?

JACK: What is it?

-JAMIE: Oh, my God. -FIONA: That looks like

the handle of something.

...in recent weeks,

the team has discovered three metal artifacts

within the structure that have been scientifically linked

to the 17th-century English politician and privateer

Sir William Phips,

a man who some believe buried a vast cache

of Spanish gold and silver in the Money Pit

back in 1687.

And curiously, after conducting

a magnetometry scan of the immediate area,

the team found evidence that a much larger,

and possibly older structure,

lies buried beneath it.

FIONA: Oh, boy.

JAMIE: A lot of debris

and stuff washed in,

but it could be much, much worse.

LAIRD: All right. Well, let's get started.

We need someone to bring the pump over,

someone to bring the generator over

and someone to bring the hose over.

Yeah. Let's go.

MARTY: The team of archaeologists are very excited

that this circular feature is actually

very anomalously large for the time period.

-LAIRD: That's good. -MARTY: They're thinking

it could be an important feature.

-LAIRD: There you go. -MARTY: Maybe connected to

the Money Pit, and they aren't even to the bottom of it yet.

I think it's going to be dry enough by tomorrow.

I hope so. Yeah.

NARRATOR: While the investigation of the stone feature

continues on Lot 5...

MARTY: Well, are we about set up?

Should be ready to roll, Marty.

MARTY: Okay. I want to see what this cave's all about.

...back in the Money Pit area,

Marty Lagina joins other members of the team,

approximately 60 feet southwest of the Garden Shaft,

where they are preparing to conduct

a sonar scan of a mysterious cavity

more than 150 feet deep

known as "Aladdin's Cave."

We've maxed out the settings,

so, hopefully, we can get a really quick scan

of the ten-foot void that we're into.

This is a good data-gathering device.

Yeah.

MARTY: Okay, go real slow.

NARRATOR: Since discovering this large cavity

during a core-drilling operation one year ago,

the team has not only obtained sonar data,

recorded on the western side of the feature,

showing a possible tunnel entrance,

but have also detected trace evidence

of wood and precious metals

in collected water samples.

-Oh, whoa, whoa! -Whoa!

CHARLES: What's that sitting

right on the end of it, right there?

STEVE: It looks like a bolt.

NARRATOR: And, just one week ago,

after inserting a camera

through a new borehole in the center of the cavern,

the team saw more evidence

of possible man-made workings.

PAUL: We should be good to go.

We just have to get it in the hole.

-Okay. Proceed. -I'll do it.

NARRATOR: Now, using the Echologger DASS710 sonar device

in the same borehole,

Marty and the team

are hoping to obtain a more definitive 3D map

of "Aladdin's Cave" to determine

if it really could be a man-made feature

that contains something of great value.

You have to open up your mind to the idea

that there are multiple treasure cavities

in the Money Pit.

Aladdin's Cave and the Garden Shaft

are legitimate targets and areas of interest

to find the treasure.

So, we have to continue

to investigate this area, and that's important.

I'm in the water.

PAUL: Okay. Still have a little bit to go.

MARTY: Aladdin's Cave is unique.

Sonar will see through the silt.

That will see through the opaque, muddy water.

Obviously, I'm hoping to see

something that looks man-made.

Uh, shelves or timbers

or chests.

STEVE: All right, so we're coming in to the cavity now.

Okay, we're going to start the scan

-in just a second here. -Okay.

Okay, we are scanning.

TERRY: Something's happening there.

PAUL: So, we're getting a return now.

PAUL: Now we're getting the perimeter of the cavern.

TERRY: There it is.

PAUL: It looks kind of, uh, crescent moon-shaped.

Okay.

-Hey, guys. -TERRY: Hey, guys.

-How are you doing? -RICK: Hey.

TERRY: We've got the image all set up here.

So, the image is very clear and crisp at this time.

Rotate it a little more, Paul.

-TERRY: Now, look at that. -CHARLES: Oh, now we're

starting to see-see the sides form.

TERRY: Excellent.

CHARLES: Do you see any evidence

of a tunnel or an entrance or...

Maybe.

It's hard to say.

Whoa. What is this?

We seem to have a sharp edge there.

Where are we looking?

RICK: The sides, right?

CHARLES: Yeah. There's two straight lines.

PAUL: They certainly don't look natural.

TERRY: Yeah.

CHARLES: There's two straight lines. There's one there

and then there's one there, right?

PAUL: Absolutely.

NARRATOR: In the Money Pit area

on Oak Island,

Rick, Marty and other members of the team

have just obtained new sonar data...

...that indicates possible evidence

of man-made workings some 150 feet deep

in a large cavern known as "Aladdin's Cave."

PAUL: They certainly don't look natural.

TERRY: Yeah.

We'll see those better

when Steve puts them in the 3D model.

-Yep. -The characterization

of this opening is, I really think,

going to give us a lot of information as to,

you know, how people proceeded in the past to dig

and work below 106 in the Money Pit area.

Keep rotating it please, Paul.

Stop there.

TERRY: What I'm seeing is the potential

that that slope there might be sand.

And this slope

could be burying whatever might be laying on the floor.

MARTY: There's a pretty square wall along one side.

Very interesting.

You almost only could come up with one explanation

why there would be man-made anything in that cave.

It was some sort of deposit of treasure.

We have a very good view here.

So, based on the data we have today,

this is the western part of the cave.

It's substantial in size.

But most importantly, we need to see where it's coming from.

MARTY: Are you seeing a potential way in?

I mean, we could go over to that direction

and see if it continues on.

-Yes. -TERRY: Yep.

RICK: I think you gotta put a drill hole on it.

MARTY: That's what I would do.

RICK: I simply want to see

a way into Aladdin's Cave.

There's a possibility that treasure does reside there.

But I think, all things Oak Island,

everything is incremental.

We're seeing a little bit of an echo here,

so maybe there is an opening.

RICK: Let's do some more drilling.

Put a camera down into it.

Let's see what-what we learn

and then make a decision on how to proceed.

So, I think everyone here is quite adamant

that we need to make a proper, sound assessment

of what this represents, right?

There are two ways to do it.

One is put another drill hole down

and put it on a more detailed,

outward-looking scan, right?

-Sounds good. -Let's do it. Set it up.

I think that's all we can do today. Nice job.

-Okay. -All right, guys.

ALEX: Thanks.

TERRY: Time's going to tell.

NARRATOR: The following morning,

as members of the team begin drilling a new borehole--

known as L13.5--

in order to collect more data inside of Aladdin's Cave...

ROGER: Okay, it's all good.

NARRATOR: ...and while representatives from Dumas

continue their effort

to stop the flow of water into the Garden Shaft...

-CARMEN: Hello. -CRAIG: Hey, Carmen.

PETER: Hey, Carmen.

-How you doing today? -Good. -Welcome back.

Got some more stuff for me, have you?

NARRATOR: ...Craig Tester, Peter Fornetti,

Jack Begley,

and archaeometallurgist Emma Culligan

meet with blacksmithing expert Carmen Legge

in the Interpretive Centre.

-Who's gonna start? -JACK: Me.

And these objects have been found on Lot 5.

CARMEN: Oh, okay.

NARRATOR: Carmen has been invited

to examine a metal strap

and a heavy fastener,

that were both found one week ago

within the mysterious circular depression on Lot 5.

JACK: What do you think about this, Carmen?

CARMEN: Well, I would have to see a scan on that

because I can't tell if that has a hole into it or not.

There you go, Carmen.

NARRATOR: In preparation for today's meeting,

Emma processed both objects

with two specialized scanning devices.

The first,

known as the Skyscan 1273 CT Scanner,

emits non-destructive radiation

that penetrates built-up corrosion on objects

in order to reveal their finer details.

The second, known as an X-ray fluorescence spectrometer,

uses X-rays to identify the elements

that the objects are composed of.

EMMA: And it is heavily corroded.

So, the red is the corrosion.

And the green is the base metal.

Yep. There's a hole on both sides.

-EMMA: Right there. -CARMEN: Yeah.

It would end right here.

CARMEN: It was very well done.

Oh, do you have any idea what that is?

Yeah, that's a clasp off a... a chest or a trunk.

-What? -Yeah.

'Cause you can see this part's sticking out here, right?

-JACK: Oh. -CARMEN: So, then you, when you close the lid,

the clasp comes down at the hinge part, right?

It comes down and then you insert a, uh, a lock or a wedge.

Oh, okay.

A chest for what, typically?

Uh, this would be a small chest. I would say 12 by 12.

Does the style of that suggest a time period? Or...

CARMEN: It is old. You know, early 1600s to the mid-1700s.

NARRATOR: A clasp

to a small chest or trunk

possibly dating back to the 17th century?

And found in the mysterious feature on Lot 5?

Could it be related to other 17th-century artifacts,

which have been traced to Sir William Phips?

The privateer who, some believe,

buried treasure from the famed Spanish wreck

known as the Concepcion on Oak Island in 1687?

If so, could they also be connected

to the precious metals that have been detected

across the Money Pit area?

JACK: Well, what's the metallurgy of this?

Metallurgy, there are no modern indicators.

Okay.

PETER: So, I'm curious about this next piece.

JACK: All the iron pieces

were relatively found in the same zone.

CARMEN: Oh, definitely a nail, Jack.

Do we have a scan of this one, so I can see it?

I do.

Can you flip the head around a few times?

What I'm seeing here is a nail that was made in a hurry

with no definitive head.

It's not a rose head or anything like that.

It was just squished out.

So, it wasn't, uh, made for anything

that was going to be fancy or pretty or whatever.

So, typical structure nail.

Okay.

We have overwhelming evidence

that people were doing something in this structure.

CARMEN: It's a very crude nail for a very crude purpose.

JACK: What would be your best guess for time frame?

Early 1600s up to 1700s.

Nice.

Um, I would lean towards the older part of that time period.

CRAIG: Emma?

-Mm-hmm. -What's the chemistry of that?

EMMA: From what I do see,

definitely pre-1800s, could be 1600s,

but it does have a higher aluminum-to-silicon ratio,

which is unusual,

but it is a signature that I'm seeing

in William Phipps artifacts,

and I've been seeing it on Oak Island artifacts.

I mean, it's good.

These two artifacts, we have two different disciplines

suggesting the same time frame, which is great.

CRAIG: Yep. Well, thank you, Carmen.

I'm hoping we have you back here very soon.

CARMEN: The sooner the better.

NARRATOR: As the team concludes their meeting

with Carmen Legge at the Interpretive Centre...

MOYA: Do you want to go look through it?

HELEN: Okay.

NARRATOR: On Lot 5,

archaeologists Helen Sheldon

and Moya MacDonald continue

their excavation of the mysterious feature,

now that the rain water has been completely removed.

HELEN: So, what we're looking for right now, really, is soil.

-Change in soil. -Okay.

-MOYA: It's that clay stuff. -HELEN: Yep.

MOYA: Oh.

Helen, I think I found something.

That's interesting.

It's really interesting, different from what we've seen.

HELEN: Oh, wow!

MOYA: Yeah.

Oh, wow. Very cool.

NARRATOR: While meticulously investigating

a deeper layer of the mysterious stone structure on Lot 5,

archaeologists Helen Sheldon and Moya MacDonald

have just made a new

and potentially significant discovery.

MOYA: What do you think that is?

That looks like a barrel strap.

Yeah, it's really interesting.

HELEN: It's got the nail through there,

that it was fastened to the barrel.

The nail almost looks like a different type of metal.

-Would you agree? -It's got a greenish hue to it.

-MOYA: Mm-hmm. -HELEN: Which probably means it's copper...

-Mm-hmm. -...on an iron strap.

I came to do a check-in, but I see I came at the right time.

-Yeah. -Look.

-What did you find? -HELEN: We've just found this.

Well, it's a piece of a barrel strap.

And it has a nail in there,

and it had a greenish tint to it, which means copper.

-JACK: Yeah. -MOYA: Would that mean anything,

if it's two different types of metal on a barrel strap?

Well, copper normally indicates it's been to sea,

you know, because they don't corrode.

But the strap itself is still iron.

I mean, a lot of things were imported in barrels,

like, that's how they shipped things.

So, that's how you transported things around.

We've also found barrel hoops around the whole island.

Near the swamp and, well,

a bunch of different places metal detecting.

Hey, guys. Check that out.

-Top of a keg. -Wow!

NARRATOR: Three years ago, while investigating

a stone pathway connected to the stone road,

or ship's wharf, in the swamp,

Rick Lagina and members of the team unearthed

pieces of wooden cargo barrels.

-So, that's a keg. -Yep.

NARRATOR: Those finds not only suggested

that an operation to move heavy cargo

from a large sailing vessel up to the Money Pit

took place when the swamp may have been an open harbor...

This one is extremely old because it's hand-made.

NARRATOR: ...but were also believed, by blacksmithing expert

Carmen Legge, to date back hundreds of years.

So, that could go right straight back to the 1400s.

NARRATOR: Could this barrel strap,

found in a deeper layer of the mysterious feature on Lot 5,

be related to the barrel pieces uncovered in the swamp?

And if so, could they offer more evidence

to support the team's speculation

that Lot 5 was used as a staging ground

for whatever may be buried in the Money Pit?

From our on-island finds,

it would seem that Lot 5 is the place

that was the encampment

to build the Money Pit.

There might be enough evidence around here to tell us

who did this and then we can finally recover the treasure.

So, Moya will put this in the bag.

And, at the end of the day,

we'll take it back to the lab

-and see what Emma can do with it. -All right.

Great find. You mind if I help sift for a while?

-Yeah, sure. Go ahead, Jack. -We'll get back to work.

-Here, I'll take your bucket. -Thank you.

JACK: Hopefully, we can find some more.

NARRATOR: While Jack helps Helen and Moya search

for additional clues on Lot 5...

-TERRY: We're getting close, Charles. -CHARLES: Yep.

NARRATOR: In the Money Pit area...

The next run should bring us evidence of the cavern.

NARRATOR: ...Terry Matheson

and Oak Island historian Charles Barkhouse

continue supervising the drilling operation

in borehole L13.5.

A borehole positioned to, once again,

penetrate the large cavity

located some 150 feet underground,

which the team has optimistically dubbed

Aladdin's Cave.

Mike, what's up?

How's it going over there?

TEDFORD: So, I hit the cavern

-around 141. -TERRY: Right.

It seemed like there's only, like,

six feet of open space there,

and then I started feeling a little muck.

We'll see when we bring the core up.

-Yeah. -Thanks a lot, Mike.

That's super news.

-CHARLES: Hey, Alex. -Charles. Terry.

TERRY: Hey, Alex, how you doing?

What's the update? L-13.5.

141 below grade, and we popped out into the old Aladdin's Cave.

-Great. Awesome. -TERRY: Oh, yeah.

Five feet of open space before we hit bottom.

Then we're into the grit and gravel

on the floor of the cavern.

Okay, that's excellent.

MARTY: This Aladdin's Cave is very important to us.

It would be a game changer if there's anything man-made

in that cave.

-Hey, Steve. -Hey, guys.

We hit Aladdin's Cave.

-We're in the cavity for sure. -That's perfect.

This couldn't have been a better hole.

MARTY: We need to try everything we can.

We have to figure out what this

Aladdin's Cave is, and if it has something

to do with the treasure.

The next step is to run the camera.

So, if you guys are ready, I'd like to see

-what's down there. -Absolutely. -Yeah.

ALEX: The overwhelming likelihood

is that Aladdin's Cave is not natural.

If it's not natural, then somebody dug it.

It's either searcher or depositor.

Where are we at?

We're just ready to put it down.

-Okay, great. -Okay, let's get after it.

ALEX: If this cave is man-made,

there must be an entrance.

So, when we lower the camera down,

we should be able to see something, and, hopefully,

we can get as much data as we can.

-TERRY: Here we go. -All right, Steve.

NARRATOR: In order to look for any signs

of a tunnel or possible treasure...

TERRY: Down the hole we go.

NARRATOR: ...the team is using

the Inuktun Spectrum 120 high-definition camera.

A waterproof device designed to operate

in low-light conditions,

and which features a lens that can pan 360 degrees

for a full view of its surroundings.

-TERRY: Few feet away. Oh. Boom. -ALEX: Boom.

TERRY: We're into the water.

STEVE: Aladdin's Cave, to me,

is probably the most interesting feature in the Money Pit.

It's a huge structure. It's almost 30 feet wide.

It has gold and silver in the water,

and it has wood organics.

So, to me, it's the most promising location

for an offset chamber.

To me, this is a potential treasure location.

PAUL: Okay, it's pretty murky down there.

We're not seeing too much right now.

Let's get into the cavity and see what we can see.

Okay.

ALEX: There you go, it's right under the lip of the casing.

TERRY: Okay.

ALEX: There you go. You got something.

PAUL: Okay. Stop right there. Stop right there.

CHARLES: Now it's starting to clear up a little bit.

ALEX: Stop there!

It's not a bad image, but what is it?

PAUL: Yeah, it looks like the edge,

edge of something here.

ALEX: What do you see there, Terry?

TERRY: I see broken edges.

Okay, now-now pan around if you can.

CHARLES: Paul, stop right there. Go back.

PAUL: Oh, okay. Yep.

Yeah, there's a linear feature,

but we've gone by it.

-It was up further. -PAUL: Okay.

Let me try to get back up there.

Yeah, tilt it up a little bit here.

TERRY: What's that?

There you go. There's...

-something there. -STEVE: What do you see?

Looks like the edge fracture of a wall right now.

Just want to take a quick look.

PAUL: We're just panning around

-to try to get the perimeter. -CHARLES: Yeah.

So, you can see this bunch of material here, Steve.

It's basically, like, an edge,

edge of a wall for the cavern.

Oh, yeah, that looks good.

What would you say that is?

That does look...

look like a tunnel.

STEVE: That does look like a tunnel.

Oh, yeah, that looks good.

NARRATOR: It is a riveting moment for Alex Lagina

and members of the Oak Island team

in the Money Pit area.

PAUL: Clearly, we're stirring up some silt with the camera motion.

NARRATOR: While investigating the mysterious cavern

nearly 150 feet underground,

known as Aladdin's Cave,

they have just obtained high-definition video

of a possible man-made entrance.

CHARLES: Yeah, there it is right there.

PAUL: See, that looks like an opening right there.

STEVE: Look, look.

Oh. It's hard to see now.

It's promising,

from what I can see just for a second

before the water got quite murky.

It did look like we could see a potential hallway or a tunnel.

-So, that's promising. -It is promising.

STEVE: I'll go get Terry back in here.

Okay. Sounds good.

PAUL: Maybe this is man-made.

We're trying to get an answer, a definitive answer.

But the question is, if we keep following this,

are we going to see something?

-ALEX: Hey, Steve. -Yes, sir.

Can you just lower it about six inches?

ALEX: Perfect. That's good.

PAUL: Now we're able to get a 360 a little bit.

ALEX: There.

-TERRY: That's kind of a sharp edge. -Yeah.

But that's going to be the open space.

CHARLES: Yeah, that's open space there.

-If I keep going... -It's pretty wide.

PAUL: Okay, yeah. So, we have a clear, open area

between two sidewalls, it looks like.

Charles, what do you see?

We're seeing, like, a dark space,

like, between two walls, and you can't see

the back of it at all.

Yeah. When I was in there, that's what I could see, too.

It almost looks like a tunnel, or an opening to a cave.

CHARLES: You know, we're into an open space.

This could be a tunnel. It could be an offset chamber.

Who knows?

And that's exciting.

We've got to investigate this

and see where it ends.

Maybe that will lead us to where the Money Pit is.

-I'm just trying to look down. -Yeah. Yeah.

-ALEX: You see anything? -CHARLES: No.

-It's very murky. -This image is so poor.

The sonar, I think is going to give us a better idea.

NARRATOR: Because of the heavy silt that has now obscured the team's

ability to visually investigate

the possibly man-made cavern,

in the coming days, they will once again conduct

a sonar scan from this new vantage point in order to better

define the dimensions of the possible tunnel entrance,

and hopefully determine

just what this feature may contain.

ALEX: Aladdin's Cave.

This really is the most significant

underground cavity that we've found in the Money Pit.

And that's why we need to explore it as much as we can.

The sonar can see through the dark,

and get us a really precise measurement of this cave,

and help us try to solve this mystery.

I think we've seen everything we can see.

I think it's gonna come down to the sonar.

CHARLES: I agree. Yeah.

ALEX: Thanks, guys.

NARRATOR: The following morning...

as the team from Dumas Contracting Limited

continues to look for voids in the Garden Shaft...

FIONA: I've got a lot of loose rocks here, and I think

I'm going to have to take them out.

I expected that at the edge.

NARRATOR: ...Jack Begley, Jamie Kouba,

Moya MacDonald and Fiona Steele

continue their careful investigation to uncover

more layers of the mysterious stone foundation near the shore

on Lot 5.

JAMIE: I will say, I'm finding

barely anything now that we're

in these big rocks, so that's a good sign for it being a wall.

I think that this is the edge.

JACK: On Lot 5, it appears that this is some sort of

habitation or structure

that predates the Money Pit discovery.

So, is this our depositor?

Is this related to the Money Pit?

Digging up these features and recovering

all the artifacts could tell us who this was,

and whether or not they are related to the Money Pit story.

So, just kind of looking at this structure, I'm struggling

to figure out how it all lines up, and how big this might be.

What I expected to find was a pretty much intact wall.

But I think it's possible that it was

a taller wall, and it has collapsed in on itself.

When you're looking down on it, you can see

these rocks here look in situ.

-Like they weren't just stacked. -Hmm.

And there is still this straight line

that we have going through here.

It kind of makes me wonder if we don't have both sides of

this rock wall, because

we know we have sterile soil over here

on the south side of it.

And it looks like Moya might be coming down

on sterile soil here on the right.

So, it's entirely possible that we got both sides of it.

NARRATOR: A stone wall?

Is it possible that the team is in the process

of uncovering another section of the mysterious feature?

And if so, just what will they find

as they continue digging deeper

into the purposely buried layer below?

I have a hunch that this thing just fell in on itself.

That it was higher than ground level,

and that it fell in on itself.

I'd like to get Laird out here and have him take a look

and get his opinion on it.

I mean, at the very least, we've definitely come down

on the rock feature that we were looking for.

-MOYA: Absolutely. -JACK: Yeah.

MOYA: It's really interesting.

JAMIE: This is really exciting to see.

-LAIRD: Hello -JAMIE: Hello.

-Hey, Laird. -What's happening?

We have an interesting puzzle.

-Yeah. -Great.

NARRATOR: Near the northern shore

of Lot 5 on Oak Island,

archaeologist Laird Niven joins Jack Begley

and other members of the team to inspect

a potentially important discovery

that was just uncovered

inside the mysterious stone foundation.

So, we might be coming down on a wall feature.

-Mm-hmm. -It's possible that this structure was

a little taller than we originally anticipated,

and it has collapsed in on itself.

That's possible.

The other thing I kind of wanted to discuss

with you, since you're here.

As we started taking back this historic fill,

we started hitting the dark stuff.

And that's all the same area that we're

finding the iron and stuff in.

-Yeah. -Like, especially, like, the door pieces.

-Right. -And we've also been finding

a lot of nails in that area around the dark soil,

-so that would also maybe indicate a door, right? -Yep.

Yeah.

The magnetometer data is indicating that there

should be at least intact base of a wall.

-Yeah. All four sides of it. -Right?

Yeah, so, I mean, what we have here is the outline of a fairly

large structure that for some reason was abandoned and either

collapsed or was filled in, or a combination of both.

-Yeah. -So it's pretty exciting.

Oh, yeah. Very exciting.

NARRATOR: The confirmation that this feature is much

larger than the team previously knew

is an exciting development,

and underscores the burning question

of why it may have been deliberately buried.

Could the artifacts that the team has found inside of it,

which have been directly connected to Sir William Phips,

the 17th-century English privateer who may have hidden

tons of Spanish treasure in the Money Pit,

offer a potential answer?

This is huge if it's as big as we think it is.

Yeah, exactly. Yeah.

-We'll just keep pulling this back... -Yeah.

...and seeing where the large rocks end.

All right. I think that's a plan.

You guys keep going.

-Okay, perfect. -Yay.

We're making progress though.

-Yeah. -All right, so I'm gonna go back

to the lab, and you guys can get back to work.

-Yeah. Great. -I'll see you again soon.

-Sure. -Thanks.

JACK: It just gets more interesting

the more we dig.

LAIRD: I agree.

NARRATOR: As the archaeological work

continues on Lot 5...

-CRAIG: Hey, Scott. -SCOTT: Hi, guys.

-What's up? -How we doing?

Not so great.

We have some issues here inside the shaft wall.

They were doing some drilling,

trying to find the source of the water coming in.

Wow.

SCOTT: And the water's coming in at quite a rate.

It was raising about a foot an hour in the shaft.

-Really? -Wow. -Yeah.

So, Roger, he's got a camera down there.

He's definitely gonna get some pictures and video.

And he's gonna show us what he sees.

CRAIG: Good.

NARRATOR: ...Rick Lagina and Craig Tester

join Scott Barlow in the Money Pit area

where members of Dumas Contracting Limited

are struggling to stop the mysterious flow of water

that continues to flood the Garden Shaft.

ROGER: Woah!

So they're going 65 feet down, where the water's coming in.

And it seems to be an isolated spot

because they've drilled around it and it's dry.

-Hey, guys. -SCOTT: Hi, Roger. -CRAIG: Hey.

-How did it go down there? -(chuckles)

I got some pretty weird things actually.

In there, there's like a little cavern

and it's full of timber in there.

-Whew. -ROGER: It's really weird.

Actually, I've got a picture maybe I can show you.

There's a long void in there.

So, you can see in here...

So that's inside the cavity. See these planks up there?

They look like one-by-six laid one on top of the other.

-CRAIG: Oh, wow. -ROGER: It's weird.

It's just weird.

-And it's not connected to my shaft. -Wow.

That makes this very interesting.

ROGER: Yeah.

There's a long void in there. It's kind of really weird.

And it's not connected to the shaft.

Yeah.

NARRATOR: It is a perplexing moment

for Rick Lagina, Craig Tester and their team

in the Money Pit area

as workers from Dumas Contracting Limited

were probe drilling in an effort

to find the source of the water flow

that is currently flooding the Garden Shaft.

They discovered a mysterious cavern

just outside the structure

at a depth of 65 feet that contains wooden timbers.

You'll see some really good shots.

ROGER: Wow, look at that.

-That's quite a cavity. -It is.

Seeing the void or the cavity,

your first thought, of course, is...

"You know, is this possibly connected to an offset chamber

"or a previously unknown void, cavity, tunnel?

And might it lead somewhere?"

-SCOTT: That's horizontal there. -ROGER: That's right.

That cavity is certainly interesting, you know?

Thought-provoking at the very least.

ROGER: Oh, for sure.

RICK: But you've got to get down there.

You've got to put your eyes on it.

And if it happens to turn out to be true, wow.

That would be amazing.

And I know I'm anxious

-to enlarge that hole if we can. -Oh, for sure.

-And have a look in there. -Yeah.

I think first thing's first.

-We need to deal with the water. -Yeah.

NARRATOR: Is it possible

that a frustrating setback for the team

has actually led to a potential breakthrough discovery

that may help them solve the Oak Island mystery?

Unfortunately,

they will have to first stop the flow of water

into the Garden Shaft before they can find out for sure.

It's pretty ironic, you know? When you think about this,

we're 200-plus years after the first shaft was dug here

and we're still dealing with the same issues

-that the first people were. -Yeah.

-Exactly. -Water coming in.

RICK: But on some level,

that's what makes this very interesting, right?

-Yeah. -RICK: The bottom line is this--

you'll find a way

and the tunnel is still down there, right?

ROGER: Yep.

And, and look, at the end of the day,

you know, we'll all put our heads together.

-ROGER: Yeah. -And then collectively,

we can have a-a good idea of how to proceed.

It's Charles who says it all the time,

"If this were easy, it would've been done long ago."

We're on Oak Island for gosh sakes, right?

Yeah. (chuckles)

228-year mystery.

If we're gonna let a little water

say to us, "Well, you know what? We're done."

- "We're done." -We're not!

We're not done. So, let's just keep going.

-Agreed. -We can solve this together.

-CRAIG: It's a plan. -RICK: Thank you, Roger.

ROGER: Right on. We'll get to it.

NARRATOR: Ever since the discovery of the Money Pit in 1795,

the Oak Island mystery has remained a complex puzzle

that is missing a number of critical pieces.

Now, thanks to the efforts of Rick,

Marty, Craig and their team,

the pieces needed to complete the picture

of what happened here long ago

may finally be falling into place.

But as they move forward, determined

to reach those answers, perhaps

the ultimate question is, will the island allow them

to be revealed?

Next time on The Curse of Oak Island...

-MARTY: Time to drain the swamp. -RICK: Do it.

RICK: The swamp holds secrets to the mystery.

-Oh! Look! -Oh!

JAMIE: That's interesting.

-MOYA: What do you got? -JAMIE: Holy crap!

It seems like jewelry.

SCOTT: A symbol found on Templar churches

pointing directly to Oak Island and it is believed

-to represent the Holy Grail. -Oh!

RICK: If there's gold in that void, that'd be huge.

There's something there.
