Original subtitles

Ator: Tonight, on the curse of oak island

Gary: Here we go. What does that remind you of?

It looks like an enormous key.

Doug: I saw a rock mound that

- doesn't look natural to me. - Marty: What is this thing?

I ain't got the foggiest.

It's like some crazy earthen work.

It's a man-made structure.

Tony: Let's go find some treasure.

As soon as you got close to the bottom,

it was that whole area that was live.

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,

mysterious fragments of human bone,

and a lead cross whose origin may stretch back

to the days of 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.

Narrator: It is the start of a new day on oak island.

- Brennan: Well, this is good. - Terry: Oh, yeah.

- I'm glad marty's gonna get a chance to look at it. - Yes.

Terry: Here he comes.

We just want to find that one thing.

Absolutely.

Here at the money pit site, rick and marty lagina,

along with their team, continue a core-drilling operation

across a strategically placed grid

to locate what people have been searching for

since 1795:

The fabled money pit treasure vault.

- Hey, marty. - Hey, guys.

Tell me something good!

Well, we think we got something good right here.

- Really? - Terry: Marty, you were saying

the other day, this bedded material,

nothing's gonna move through this.

Right.

Terry: We got 28 feet of loose material

from 179 all the way down to 207.

Marty: Wow. Yeah, that's a lot.

Yeah. This is kind of what we're looking for.

Terry: Oh, yeah. That is as close

as you're gonna come to a true open void.

- Yeah. This could have caused. - So...

- The collapse of the money pit, right? - Absolutely. This is the type

of material that we lost the h8 plug into.

I'm sure of it.

- Charles: That's why we had to show it to you. - Yeah.

Well, I'm glad you did.

Narrator: In 1861, searchers from the oak island association

constructed an adjacent shaft

18 feet west of the original money pit,

known as shaft six.

At a depth of 118 feet,

they began tunneling east through the dry ground

in the hopes of retrieving the treasure from below,

while avoiding the man-made flood tunnel

originating from nearby smith's cove.

Unfortunately, just six feet shy of their target,

ocean water broke through and rushed in,

nearly drowning two men.

It not only ended the effort, but just days later

caused a catastrophic collapse

of the tons of wood and steel cribbing in the money pit,

leaving the fabled treasure lost somewhere below.

Three years ago, while excavating

a five-foot-wide, steel-cased shaft known as h8,

rick, marty and the team

believed that their caisson may have encountered

the legendary vault.

But unfortunately, when they dug deeper

in an attempt to penetrate it,

the object they hit was pushed further down

and somewhere off to the side.

That went from all the way from up there

down through...

To land just about a foot above bedrock.

- Yeah. - So, that would have a density

- of about three or four. - Yeah.

Gold is 20. Silver's about 11.

So, gold and silver

would fall quite easily

through this very, very soupy material.

- Proof positive stuff's moving around down there. - Absolutely.

Yeah.

The region of the solution channel

that is, uh, sufficiently not filled

with things like clay,

such that things could move around underground.

But more to the point,

we'll know if there are areas in it

where this treasure could have fallen down and moved.

: I want the great treasure to surface.

Marty: Did you metal-detect this?

Yes. Yes. Nothing.

- Where is it?! - Not yet.

- Not yet, marty. - Yeah, I know, charles, I know.

We're getting into the interesting zone right now.

Well, hey, this is a success of sorts.

- That's right. - Absolutely.

All right, keep going, guys.

- Will do, marty. Take care. - Terry: Absolutely. - Yeah, thanks.

Narrator: While the drilling operation continues at the money pit...

- Here we are, mate. - On lot 13,

metal detection expert gary drayton

and rick and marty's nephew, peter fornetti,

are searching an area that rick, marty and craig recently cleared

of trees and heavy foliage.

It was also near this area that, three weeks ago,

oak island theorists chris morford and corjan mol

presented their belief that priceless religious artifacts

connected to the knights templar could possibly be buried.

- All right. - We're gonna find something today.

- Let's go. - Okay, mate.

Gary: Peter and I

are gonna be doing a lot of digging,

because the stuff that I've brought this year

is gonna be detecting targets really deep.

And this is an area

I'd never been able to get into,

because it's always been so overgrown.

All right, so, get ready for some digging, mate.

Ah.

It's iron, but it intrigues me

'cause it's right next to this big boulder.

Gary: All right, you got it out, mate.

- I see it. - Ox shoe.

Gary: Is it?

Yes, it is. An oldie as well.

- Peter: Mm-hmm. - Look at that.

Yeah, I like this because the width of it.

That tells me it's more than likely it's a british ox shoe.

Yep.

And it's an oldie, 'cause this is really heavy.

Yeah, I'd go back easily to the 1700s on this one, easily.

Narrator: An ox shoe?

Possibly of british origin

and dating back to before the discovery of the money pit

in 1795?

- Jack: Ooh, there's another one! - : Another ox shoe.

Narrator: Four weeks ago, gary and jack begley

found similar ox shoes on lot 15,

and also a finial, or decorative harness piece,

just yards from a rock structure believed to be the remains

of a possible 16th-century british military pine tar kiln,

one possibly linked to the massive stone-paved area

discovered last year in the swamp,

as well as the construction of the original money pit.

Okay, we'll keep going.

Ooh.

Yeah, it's in there, mate.

Do your best. Just dig a hole and try and get

- the pinpointer in there. - Yep.

See if I can winkle it out.

- Ooh, another ox shoe. - Ox shoe.

Gary: Yeah.

Another chunky one, as well.

Which way was I going? I think I was going that way,

- wasn't I? - Yeah.

Oh. Just there, mate.

Oh.

- Another ox shoe! - Wow.

We've pulled up several different ox shoes.

The interesting thing about ox shoes

that we're detecting is they all seem to line up.

A path on oak island can only mean one thing:

It's a trail.

Trails are important, because trails are areas

where cargo was hauled.

So is this a potential treasure trail?

We've got a trail that obviously leads down to the beach

and the old wharf, mate.

Headed more towards the swamp

- than anything else. - Yeah. Yeah.

Narrator: Could gary's suspicion be correct that,

just like the pathway he found

between the swamp and the mysterious structure on lot 15,

he and peter have discovered evidence

of another pathway used to transport cargo onto oak island?

If so, what kind of cargo was it?

And where did it end up?

Good digging, mate.

- I'll go down there, I'll keep the same line. - All right.

Here we go.

Just here, pete.

Ooh! Look at that!

Wow.

Ke some kind of lynchpin.

Peter: Isn't that similar

to what carmen thought was a decorative piece?

Yeah, that is. That is very similar.

Narrator: On lot 13, near the northern shore,

metal detection expert gary drayton and peter fornetti

have just discovered what may be evidence

of a pathway once used to transport cargo of some kind

onto oak island.

I'm not gonna mess with this.

I'll let the guys clean it off

and see if it is similar to that other piece.

- Yeah. - I think you should call

your uncle, mate, and get rick to come down

- and show him what we've found in the area. - Yeah. I'll give him a call.

Gary: We've just pulled up a really nice little artifact, and...

It makes me believe

that there was some hauling going on of cargo.

Hey, guys.

- Hey. - All right, mate?

I thought they might enjoy seeing your finds.

Yeah. The interesting thing about these finds is

they're very similar to the finds

that we recovered on lot 15.

And we know the date

and the nationality we got back

on those artifacts.

British and old.

And I'm not talking about me.

We have found some cool artifacts.

You see that one there?

What does that remind you of?

What we found on lot 15.

Rick: Yeah, that's the thing that you referred to as a

Gary: Yeah, I thought it was, like,

- a-an ox knob off a-an harness. - Mm-hmm.

But it turned out to be an old finial.

Terry: It looks like an enormous key.

- Peter: Yeah. That's what he thought. - Rusted key.

It kind of looks like a key, doesn't it?

- It does. - All three

ox shoes and that finial

- were all found within, like, a 15-foot radius. - Yeah.

- Oh, really? - And they all seem

to be leading

from the beach towards you-know-where.

But look at that.

- Look at the weird... - Yeah. That's huge.

Gary: They're all british ox shoes.

And we know. We got the dates back, mate.

It could go back, you know,

early 1700s, even in the 1600s.

That's bloody brilliant!

And so we replicated a success on lot 15

down there in just the place we need to,

opposite that old wharf.

- Rick: Great finds. - Terry: Absolutely.

- Thanks. - All right, well, good luck. - Okay.

- All right, thanks. All right. - Happy hunting.

- Rick: See you, guys. - Gary: See you later, mate.

Cheers.

Narrator: Later that afternoon

Rick: Let's get these last two holes drilled.

- Sure. - Get the rig back up and running

- and we'll move on. - Narrator: While rick lagina,

charles barkhouse and terry matheson

continue to oversee the drilling operation

in the money pit area

Jack: It's a gorgeous day to dive.

It is a gorgeous day to dive, jack.

Marty lagina's son alex;

His cousin, peter fornetti;

Jack begley;

And professional diver tony sampson

meet at the nearby marina

to begin a dive operation

to explore the waters surrounding oak island.

Tony: Okay.

- Let's go find some treasure. - Alex: Yeah.

Narrator: In addition to their planned investigation

of a possible shipwreck just off the island's northern shore,

they will also be exploring

another possibly man-made feature

that alex, tony

and geoscientist dr. Ian spooner

discovered during their sonar scanning operation

near the swamp.

Ian: This might be, uh,

evidence of a human-made structure.

The remnants of an old wharf, something like that.

Narrator: The team hopes that, today,

they can determine if this feature

might be connected to the discovery made last week

by rick lagina and dr. Spooner

while they were probing in the swamp's southeastern corner.

Do you hear that?

There's rock here.

That could be it.

Rock.

And it's flat. It's all exactly the same depth.

It's like a road across the swamp.

This is very interesting.

Tony: Okay, so what we're gonna do now

is we're gonna head out to that number one target,

and that was the one that me and alex and, um,

dr. Spooner saw out there that day.

So, alex saw a really large spike when we got there.

There might be a shipwreck out there,

and maybe they had captured another ship

and they used iron or, um, cannonballs.

We have no idea.

You'll see the line when we get out there.

Me and alex actually marked the spots.

So, we're approaching

the boulderless beach area now, guys.

And, um, what I've got on my screen here

is all these strange features.

So, it's almost a line that goes right up the side of this beach.

So, what we're doing is we're approaching

that first mark here.

- Jack: Are we diving on it? - We're diving on it.

So, let's throw the block over and, uh, see what we get

- down there for depth, buddy. - Alex: Okay.

- Tony: So, that's our mark, alex. - Okay.

Narrator: Even though they are restricted by canadian law

from removing anything from the ocean bottom,

tony and alex will use a metal detector

capable of identifying both ferrous metals such as iron

and nonferrous metals such as silver or gold.

Tony: Okay, so what we've got here, guys,

is a pulse 8x metal detector.

So, we'll scan the area with that.

On the bottom, the vis is not as good as I hoped.

The waves are beginning to pick up.

We'll communicate by comms.

If we have a problem and we lose comms,

- then it's just back to hand signals. - Alex: Okay.

Probably go out 100, maybe a couple hundred feet.

- Okay. - That way, we cover that whole area.

- Yeah. - Okay. We're on.

Jack: Looking great. Yeah.

Tony: Good, buddy.

Good luck.

Nice. Splash down.

All right, going down.

Narrator: Multiple signals for metal objects?

Could tony and alex have found the location

of some kind of structure that is buried

just below the bottom of the ocean?

Unfortunately,

due to canadian law,

they are prohibited from digging to find out.

Comms check. Comms check. Over.

Comms check. Comms check. Over.

Nothing.

Everything looks to be working.

You want to try it one more time?

I can.

Comms check. Comms check. Over.

Nothing.

He northern shore of oak island,

jack begley and peter fornetti have just lost communication

with alex lagina and tony sampson,

who are diving in some 30 feet of water,

attempting to investigate a buried metal structure.

Comms check. Comms check.

Comms check. Comms check. Over.

Narrator: Due to the decreasing visibility

and danger of continuing to dive in this location...

Can you hear 'em, even a little bit?

I can hear 'em a little bit.

And also because they are unable

to communicate with jack and peter on the boat,

alex and tony decide to make their way back to the surface.

Jack: I'm keeping an eye out for 'em.

Peter: I don't see 'em.

It'd be nice to hear what they're talking about

- down there. - Yeah.

Jack: Oh, they're up!

Yeah, that's alex.

Yeah, there's tony.

Peter: They're both up.

The wind picked up,

started muddying the waters down below.

And so that is what caused...

All the stuff on the bottom started picking up.

And, again, just like always seems to happen,

we got a perfect day for it and something goes wrong.

Tony: I could hear you guys clear. Could you hear me?

Peter: Well, we could... The speaker, the volume

was very, very low.

- Okay. - So, I could make...

That's why we were doing so many comms check,

- 'cause we couldn't hear. - We thought it was broken at first.

- You and I could talk on the bottom. - Tony: Yeah.

- Peter: Yeah. - I think I heard you guys at one point.

- But I was having trouble just understanding. - Yeah.

But I-I heard enough to know that

I mean, I saw enough to know the visibility was crap.

- Mm-hmm. - As soon as we hit down,

- just a cloud. - Yeah. - When we had the wind,

um, coming out of the south like we were supposed to,

yeah, we were actually not moving too badly.

But then we actually felt it

- change direction on the bottom. - Alex: Yeah.

But that's when we came across those two boulders

on the bottom.

The metal detector just went nuts.

- Alex: Yeah. - Narrator: Two large boulders?

Are they natural features?

Or could they,

like the numerous mysterious boulders around oak island,

have been placed here for some purpose?

And could they be connected

to the multiple hits tony received

on his metal detector?

Jack: What made the boulders look

so weird?

They were the only feature there.

- Alex: Yeah. - And by that stage,

the metal detector had quieted down

but the same thing as to... soon as we got close

- to those rocks... - I heard that one. I heard it.

It-it went off again, yeah.

So there's definitely metal anomalies in the area.

- Yeah. - Yeah.

Now we know there really is a metallic target down there.

We've confirmed it with a metal detector.

And the comms failure is just another check mark in the, uh,

weird, sort of, electromagnetic column.

I really don't know what to make of it.

We need to keep investigating.

Tony: The weirdest thing is, you know, it's almost like

- something didn't want us to find... - Peter: Yeah.

What was down there, 'cause as soon as we hit the bottom,

- things snapped like that. - Right.

- Yeah. - Tony: So, if we go around

and we do the second target,

then just throw me in.

- I'll go down for a quick look. - Yeah.

Tony: And, uh, if we have the visibility like we've got here

- at the moment, then it's a bust for the day. - Yeah.

- If it is better, then, you know. - Tony: Yeah.

If it's better, then great, we'll do it together, buddy.

- Alex: Yeah. - Sounds like a good plan.

- Okay. Let's do it. - Let's do it.

Narrator: While peter, alex, jack and tony

make their way toward the waters near the oak island swamp.

- Doug: Hey, gentlemen. How are you? - Marty: Hey, doug.

I understand you got something interesting for us.

Yeah, I think, maybe.

Narrator: In the research center,

brothers rick and marty lagina,

along with dan henskee,

who worked for nearly five decades

with the late dan blankenship,

join oak island historian doug crowell

and surveyor steve guptill

to hear about a potentially important find

doug has made while exploring the area

near the believed 16th-century pine tar kiln

on lot 15.

Doug: So, I was out looking at the rock walls

on the lot 15 on the hillside there,

where david macinnes is digging

- this year. - Yes. Yeah. - Yeah.

And I just was wandering around, and I saw a rock mound

that doesn't look natural to me.

I have some film. I set up a gopro out there.

- Let's look at it. - Rick: Bring it up.

- Marty: Oh, yeah. - Rick: Those are some big stones.

Doug: They are. It's strange.

So, I'm filming this,

and I'm watching the videos I was taking,

and I got curious about this rock structure

because it's on the highest elevation

of lot 15. So, it's the highest point on the island.

This structure, once I got looking at it,

I realized it's quite long.

It's this ridge of-of boulders and soil.

- Do you know this, dan? You recall seeing this? - Um...

Oh, I have a vague memory.

It was not of prime interest.

We looked at everything and then tried to classify it,

but, uh, we certainly were more interested

in anything that had to do with the treasure hunting.

Doug: There's no sign of...

Of field clearing up there. If you look around this area,

it's as rocky as all get-out.

- Well, let's go look at it. - Let's do that.

Rick: When we go out to lot 15,

I hope that it leads us to a tunnel.

But the other hope is

that the archaeologists will come up with an answer

as to what it is and why it was put there.

Marty: All right. Well, let's go have a look.

I'll grab my gear, and I'll meet you guys out there.

Doug: Dan, you want to drive with me?

Dan h.: Better than walking.

While rick and marty lagina head to lot 15

to inspect the mysterious mound discovered by doug crowell

Tony: So, we're gonna go around, and we're gonna look

at that second anomaly on the south shore side,

- and that was that square-shaped structure. - Yeah.

Narrator: Professional diver tony sampson,

alex lagina,

peter fornetti and jack begley make their way to the waters

just outside the triangle-shaped swamp

to investigate a mysterious feature

recently discovered using sonar.

Okay. So, what we're going to do, guys, it looks like

with the wind blowing us this way,

um, we're gonna do a drift dive.

And if that works well with you, alex, I'll leave you up here

- with the guys. - Yeah, it's fine with me.

I mean, with the weather the way it is now,

it seems like a more technical dive.

So I'll stay topside.

Fantastic. Let's do it.

Alex: After we dive the first target,

it's really obvious that this is a...

Kind of a more technical dive

than I'm used to.

The wind picked up. Visibility was zero.

So surface conditions are a little dangerous.

Narrator: Since the communication system

is still not functioning properly,

tony must perform this dive not only alone

but also with no ability to speak with alex,

jack and peter back on the boat.

Jack: Tony, you want your detector?

Good.

Alex: Back up.

You're good.

Jack: Now we just wait

- 'cause he doesn't have comms or anything. - Peter: No comms.

Follow the bubbles.

Jack: I know we had other anomalies in the past,

but what was it that you and tony were going after

in this spot that was of the higher interest?

Well, the thing we saw on the side-scan

is kind of coming off the swamp,

there's a strong drop-off.

And if the square structure is part of that,

then we could be looking at maybe the remains of a wharf.

But tony should be able

to see if that's a natural drop-off

or not.

- Tony's got the experience. - Peter: Mm-hmm.

He'll know something of significance

when he sees it, and I just hope

he does. I hope he finds something.

Peter: Yeah, absolutely.

Narrator: After several minutes of searching,

suddenly, tony finds a square formation of rocks

near the south shore bordering the swamp.

But is it a natural feature or a man-made one?

And could it also be connected to the flat, rocky surface

that rick lagina and dr. Spooner found

at the swamp's southeastern border?

Jack: Tony's up.

Alex: Welcome back.

Let me put these in front of your left foot.

Fantastic, thanks, buddy.

- How'd it go, tony? - Tony: Well,

it was good, mate.

Uh, visibility was a lot better that time,

but, um, current the whole way.

What about, you know, the feature that we saw with ian?

Did you find the square structure?

Tony: Um, I found

- there were rocks in a square. - Alex: Mm-hmm.

But maybe the remains of an old, cribbed wharf.

This probably was

a solid feature leading into the swamp area.

Jack: I know from different underwater

3d models that there is this box-shaped structure

just off the coast.

- Whenever you're ready. - Jack: But when tony said

he saw it visually for himself, I believe him.

I think there's something there. It's not just in the surveys.

Now we have confirmation visually from tony.

I think we need to investigate this a lot further.

Tony: Well, guys, interesting day on the whole.

Um, anomaly one over there, I think we definitely showed

that we need to go back and have another look at that, alex.

- Yeah. - Tony: That was weird.

You know, we got those hits on the metal detector.

Comms was interfered with.

Site number two, again,

that square structure

also worth a look in better weather

and might be able to improve what we see

- through these channels here. - Alex: Yeah.

We could really use a way to-to visualize

the whole bottom down there.

- Uh... - I-I totally agree, alex. Yeah.

I think we should go back and, uh,

get everybody together in the war room,

- tell them what we found today. - Sounds fantastic.

- Okay, we'll start heading back. - Alex: Cool. - Peter: Perfect.

Narrator: As alex, jack, peter and tony

finish their dive operation

Marty: Right in there?

Doug: Yeah, just on the other side, here.

Narrator: Rick and marty arrive on lot 15

with dan henskee and doug crowell

to inspect the mysterious, mound-like feature

doug recently discovered.

Rick: I'm looking at it,

trying to disprove it, right?

Well, the other option would be it's from a dig,

and there's a considerable-sized dig that fred did.

But, if you're with a crane, you start piling, right?

You don't want it too high 'cause it could be dangerous.

- But you'd fill in the middle. - Hmm.

Rick: So, it's almost like, okay,

they pointedly left that area open.

- Like who? - Transient people.

People who just stopped here and-and did

- some work and left. - Is that what you're thinking, though?

- I mean... - I don't know.

Marty: I never noticed the rock structure the way doug has.

In my observational system,

I would've just said, "oh, there's another rock wall."

The difference with this one

(is, a) it's not on a property line,

and it seems to have some sort of pattern to it.

So, it's-it's actually quite a lot different

than the other rock walls on oak island,

which makes it interesting.

What I'm trying to do is, it's fun

to guess at the sort of interesting concepts

of what this might be.

Let's guess at what

- the mundane concept might be. - Doug: Right.

It could be the bulldozer push

- from an excavation of some type. - Marty: Okay.

But the problem with that is.

From where?

Well, there's dunfield's ditch right over there.

Marty: Well, where are the spoils from dunfield's ditch?

You'd think after ten years, we'd know what happened here.

Just so many different stories from what you would consider

- legitimate sources. - Yeah, I know.

Well, let's get, uh, gary here. Metal detect it.

Step one. Step two,

we'll get those dreaded archaeologists up here.

See if they can see something.

Rick: In my mind,

it certainly warrants further investigation.

Probably the next step is to get laird and aaron

and-and david macinnes over to take a look at it.

Marty: What is this, rick?

Rick: I don't know.

Rick: There has to be ox shoes around.

These stones are far too big

- to move around by hand. - Yup.

Narrator: On lot 15, some 200 yards north of the money pit,

rick and marty lagina,

dan henskee and doug crowell continue to inspect

what they believe to be a man-made mound.

Marty: Here comes the maestro.

What do you make of this, gary?

Wow! What you found?

Narrator: Having been called to the site

in order to help search for potential clues,

gary drayton arrives to scan the mound

with his ctx 3030 metal detector.

That's

Marty: What is it?

Why don't we ever notice these things before?

It's just like

Marty: I don't know. It's such a small island.

I ain't got the foggiest. This is crazy.

Doug: Try standing up on top of it, gary.

It looks a lot different standing on top of it.

What in the world?

It's like some crazy earthen work, isn't it?

- Mm. - It's not too far away from

that pine tar kiln operation in this area.

Marty: Yeah.

This stone feature has got direction.

Maybe we've got some kind of roadway leading up to

either the feature on lot 15,

or maybe it turns a corner and goes straight to the money pit.

Marty: There's that sound.

- Gary: I'll do the top first. - Hello.

Narrator: Also having just been informed

of the potentially important find,

archeologists laird niven,

liz michels and dr. Aaron taylor arrive

to offer their professional assessment.

Laird: What's going on, guys?

Well, you're-you're sort of walking on it.

Uh, we want you to tell us what's going on right here.

What is this thing?

Aaron: It sort of reminds you of, uh,

a little bit like the serpent mounds in ontario.

Laird: Yeah.

Seriously? That occurs to you? That-that... It does?

Well, it's-it's long.

It's got a lot of dirt on top of it.

Narrator: Located nearly 1,100 miles west of oak island

in keene, ontario, canada,

the serpent mounds park is comprised of six

elongated curved mounds measuring up to 180 feet long.

Dating back as much as 2,000 years,

these so-called "serpent mounds"

are believed to have been made by an ancient culture known

as the point peninsula complex.

Is it possible that this mound, found on oak island,

could be evidence of human activity dating back hundreds,

if not thousands of years?

- Rick: Have you seen them? - Aaron: Yeah.

Marty: What was the purpose of those?

Do-does anybody know?

Uh, I think, uh, ceremonial. Um,

I don't believe they'd found any burials in them,

to my recollection.

But I think they were mostly ceremonial.

My issue would be,

kind of proximity to some of what fred did.

No, I already asked tom. Tom said, "no."

Tom said there's no way. He has video.

It's not his dad's work.

Well, the dirt on it is what's confusing me.

If it just was boulders, if I was just clearing,

why would I cover it in dirt?

That's what I find interesting for me.

Right.

The structure of it's kind of odd for a spoils pile, too.

I mean, the length would be fine,

- but all this... - Marty: Yeah. And why the hollow

- in the middle? - Where it's kind of... Yeah.

The water's right there,

but I would think that, you know, something

like a bastion or like a fort wall

would be a little bit closer.

- Laird: The higher ground. - Liz: The higher ground.

Doug: When you're standing beside this mound,

it just looks like a long row of rocks and soil,

and it's not until you get up on top of it

that you realize the scope of this structure.

It's about 130-some feet long from what looks like a tail.

I mean, what's going on on lot 15?

Laird: It might be an idea to...

To try to do a 3d model of this.

Maybe give us a different perspective?

- And then... - A really good, top-down look

- at, uh, the shape of it. - Yeah.

- It is curious. - Yeah.

All right, so, what's next?

I think you're gonna continue cleaning it off.

Um, steve and I can come back

and get a 3d representation, as best we can.

So, at the minimum, it's a head scratcher again.

Steve g.: I think for us to get a real understanding

of this, laird and I need to do some work.

And when we can get a good aerial view, create a 3d model,

then we can get a good understanding of what it is.

'Cause standing here, it's impressive,

but it's hard to picture what it is by standing here.

And you can't twist it around and look

at different angles, right?

Doug: Well, guys, I think what I might do,

once we're done cleaning this off is,

I'm gonna look into the history

of serpent mounds across the world, and

the symbolism that might be in an effigy like this

and see what I can find out.

Marty: All right, well, let's get after it.

Doug: Yeah.

: Jack, why don't you get craig and marty up?

Call 'em up.

- Hey, guys. - Tony: Hey, guys. - Alex: Hey, guys.

- Hey, team! - Hello.

- How are you doing? - Good. Fantastic.

Narrator: One day after their dive investigation

in the waters surrounding oak island,

alex lagina, jack begley,

tony sampson and peter fornetti

gather in the war room with rick lagina,

along with craig tester and marty lagina on video conference

to give a full report on their findings.

I'm gonna turn it over to the guys and let them

give us the download as to what happened on the dive.

Great!

I got to say that was one

of the more difficult dives I've ever done.

- Oh. - Just in terms of visibility,

and it did feel like when the wind picked up, it felt like

there was some movement that started happening down there,

- as well. - Tony: It went to hell in a handcart.

Went from nothing to about 30 knots out of the west.

- Wow! - Tony: What we did,

we went out, and we hit the anomalies

that we, uh, had targeted out there.

And so, the first one was the one

of most interest, I think, alex, wasn't it?

- Yeah. Yeah. Definitely. - Yeah.

So, that anomaly was the one off boulderless beach.

When we actually went down and dove it,

we did actually come across a couple of boulders.

Yeah.

Tony: And the metal detector was going off,

but we couldn't get any perspective

as to what we were looking at there.

Alex: Right. So bottom line,

there's something down there

that's setting off the metal detector.

You know, when I see gary do metal detecting,

it's very specific.

It's like one little place where he...

Then he zeroes in, and you dig, and that's where it is.

Was it doing that, or was it kind of a broad area

where it was detecting?

No. It was the broad area, marty.

- Okay. - Jack: So, is it something

big or a-a debris field

of a bunch of different, smaller objects?

'Cause if you have something big,

it will just go off on the whole area.

It was the whole area.

We probably still need to do more work there

to figure out what it... What it is because it

I believe that it is something at this point.

- Yeah. - I think we need

to fit gary with some fins.

- What else? - Tony: Um, the second one was

on the southern side of the island.

And that area protrudes in towards the swamp.

And so, there was an anomaly there,

like, square, rock-shaped structure.

So, that sort of fits into the whole idea

that that could have been an inlet into the swamp there.

But again, due to the visibility,

we couldn't get too far into that, as well.

So, that would have to be

another dive on a... On a day with better visibility.

Diving as kind of a search was difficult,

but maybe we can use some other technology to scan this

and maybe get a map of the bottom

- that we can use. - Yeah.

This confirms the need

to exploit this area,

including the discoveries in the swamp, particularly.

They've got some metal detecting hits,

and they confirmed some anomalous features.

But both alex and tony said,

"look, it's limited what we can do."

There's water clarity issues. It was hard

to maintain their position.

That demands us

or focuses us on that very thing.

Sounds good to me! Good job, guys! Sorry about

the sudden curse of the wind shift.

- It's oak island. - Alex: Yeah. Well, we still call it

- a success on the boat, and I think... - Yeah, absolutely.

- It was a success. - Yeah.

Oh, I think so, too, because...

Because you proved that it's worth further investigation.

If you'd gone down there and got flat bottom

and no metal detector hits, I think we could probably say

we're done with this, but we aren't done with it.

So, that's good.

There's a lot of hope and promise here.

- Yeah. - Marty: All right, guys.

That sounds like a successful mission

- with more missions planned. - Alex: I think that

- sums it up, right? - That's about it, yeah.

That sums it up.

The search continues.

Narrator: For rick, marty, craig and their team,

the clues that could help solve a 225-year-old

mystery continue to mount

both on and in the waters that surround oak island.

They serve as further evidence

that someone went to great effort

to hide something of incredible value.

But as the laginas and their fellowship keep searching,

where will the evidence ultimately lead them?

To a vault buried deep in the money pit

full of gold and historical documents?

To priceless, religious relics hidden in the swamp?

Or are they following

a deliberately laid trail of enticing clues

carefully designed to fulfill a deadly curse?

Narrator: Next time on the curse of oak island...

- You guys ready to make some history today? - Yeah.

It's somewhere from 400 bc to 900 ad.

That is fan-dabbing-tastic.

- That looks like it's hand-hewn. - It looks like

- a slipway, doesn't it? - You are right.

Erin helton: La volta bas de terre

is pointing right to the vault.

Zena's map has been pointing to the vault

- this entire time. - Wow.
