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

- RICK: That's a beam.
- Yep.

BILLY:
Somebody stacked those cobbles.

This might be part
of the flood tunnel.

Wow.

JACK:
If that is strapping,

that would be on a chest.

Yes. Now, that is interesting.

JAN:
We're gonna insert this radar

- to look for voids.
- CRAIG: Okay.

127 feet from the surface,

we get a void space.

This could be
the fabled offset chamber.

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.

♪ ♪

GARY: Here we go. It's
gonna be sloppy today.

PETER: Yeah, it is.

NARRATOR: Despite
the foreboding skies

that shroud a new
morning on Oak Island,

the hope of a major
discovery remains high

for brothers Rick and
Marty Lagina and their team

as they dig at Smith's Cove

for clues that could help
solve a 229-year-old mystery.

- PETER: Hey, Craig.
- Hello.

- How's it going today?
- GARY: It's going good, mate.

No fantastic artifacts just yet,

but I'm hoping for them to
come up, whatever they are.

And Rick pulled out a
really nice piece of concrete.

- Concrete?
- PETER: Yeah.

And I believe that's part

of the story of this area.

Let's make some
treasure headlines today.

Okay, Gary. We're ready.

NARRATOR: One week ago,

the Oak Island team
began an excavation

in search of a
stone-lined flood tunnel

which is believed
to feed seawater

into the original Money Pit

in order to protect the
fabled treasure vault.

After studying a detailed
survey map of the area,

which was created

by the late treasure hunter
Bobby Restall Jr. in 1963,

the team was able to reach
a depth of some 30 feet,

where they made a
potentially critical discovery.

RICK: This is the first bucket

that has a bunch of
same-size cobbles.

That is the description
of the flood tunnel.

NARRATOR: Incredibly, after
unearthing potential evidence

of the flood tunnel...

- Is it concrete?
- Yeah.

NARRATOR: Rick found
a large fragment of concrete

which may be the same material

that the Restall
family mixed and used

during a failed
attempt to plug up

the fabled booby
trap back in the 1960s.

Emma is testing it,

so we may be able to
get some answers on

what range it may come from.

- Well, I'm ready to find something.
- Yeah.

- Same here, mate.
- Okay. Sounds good.

NARRATOR: Today,
the team is hoping

to not only confirm the
location of the flood tunnel

but also track it back
to the Money Pit area,

and determine just where
the treasure may be buried

deep below ground.

- Hey, Rick.
- Hey.

Kind of soupy, eh?

CRAIG: Yeah.

RICK: If we find
the flood tunnel,

we follow that up, it should be

a direct line to "X
marks the spot."

And that's my hope,

that ultimately, we
solve this mystery

for all the people that
have come before us

looking for answers.

There's something right there.

That is one weird-looking board.

- (chuckles)
- CRAIG: Yeah.

CRAIG: Hey, Billy.

- What's that?
- It looks like there's a board

right at the water
level right now.

- Do you see it from there?
- I think so, yeah.

I'll see if the water
that's in the hole

- might help clean it off.
- Okay.

RICK: It does look shaped.

CRAIG: I'm gonna give
Steve a call, have him mark it.

RICK: As Billy digs, we
have everyone looking

for something that was
built by human hands.

Lo and behold, there's a board.

I am curious about
who built this structure,

searchers or
original depositors.

(chuckles): It's difficult
not to want to go down

and put your hands on it
and take measurements.

Unfortunately, it's too deep.

Hey, guys.

- Steve.
- Hey, Steve.

If you'll step
right where I'm at

on this side, kind of,
see a board sticking out?

Yep.

BILLY: Two boards, on this side.

RICK: Yeah, I see that.

STEVE: Yeah, it looks
like it's pretty much on top

of the projected line.

I mean, the Restall survey
plan from '63 is quite accurate.

So, if the flood tunnel
was gonna be down here

and they really did
find it, it looks like

this wood lines up with
the potential flood tunnel.

- Yep.
- We're... just got to keep going.

It's worth digging.

NARRATOR: As the excavation
at Smith's Cove continues,

later that morning...

RICK: Well, welcome everybody.

The reason for
today's meeting is,

Jan Francke, who is gonna
bring some real interesting

technology to bear.

- Yeah.
- Absolutely.

NARRATOR: Rick,
Craig and other members

of the team meet in the war
room with Dr. Jan Francke,

a world-renowned
ground-penetrating radar expert

who has not only designed
technology for scanning

the pyramids of Giza but also
the subsurface of the Moon.

RICK: We all know that Dr. Fred

and Dr. Spooner
are currently resistant

to additional drilling in
the so-called "Golden Egg."

Yeah.

CHARLES: We have a core.

NARRATOR: Over
the past three weeks,

the Oak Island team
has been conducting

a core drilling operation in
the so-called Golden Egg,

a 30-by-15-foot oval-shaped
area in the Money Pit

where groundwater testing

has identified a large
source of precious metals

somewhere between the
depths of 80 and 120 feet.

Nothing to write home
about, unfortunately.

NARRATOR: However,
after drilling several boreholes

and recovering no solid
evidence of treasure...

We'd like to stand down on
drilling in that area right now,

and let the site sort
of settle, if you will.

NARRATOR: geoscientist
Dr. Ian Spooner

and hydrogeologist
Dr. Fred Michel

have directed the
team to temporarily halt

all drilling within
the Golden Egg.

This will allow the
groundwater to settle

while they conduct
new water tests.

I'm gonna turn it over to Craig

because he found Dr. Francke.

NARRATOR: In the meantime,

Craig Tester has
reached out to Dr. Francke

to see if he can offer
another scientific avenue

to help pinpoint the location
of the believed treasure.

So, we've run ground-penetrating
radar in the past,

and I'm always looking
for updated technology,

and one thing that he
does have is a borehole

ground-penetrating radar.

And-and I'll let you
go into the details

- of the tool.
- JAN: Sure.

Now, my background

is a geophysicist, and I
designed GPR systems

for a variety of
applications. And so,

this is a hundred-megahertz
borehole radar antenna.

The idea with the
borehole radar is to combine

all-in-one, self-contained tube,

which is what we
have here today.

So, what we hope to see
are very obvious targets.

It'll be of interest to all of
us, I can guarantee you that.

NARRATOR: The
100-megahertz Helix borehole radar

is a device that sends
electromagnetic pulses

through the earth which
can identify anomalies

such as structures,
voids and metal objects.

JAN: When you're
looking at a borehole

in your environment,
it's kind of like looking at

a painting through a straw.

And what I'm hoping to do
with this technology is expand

the size of the
straw a little bit.

JACK: So, if you
run this equipment

around the Money
Pit, you're rather sure

that if-if there is a treasure
or some sort of a vault,

you should be
able to pick up on it?

JAN: Yeah, I
would, I would think

we're looking for an
air or water-filled void.

That would be a
very strong reflection.

So, what we'll see is, if
there's any target underground,

we'll know the
depth and we'll know

the approximate distance
away from the hole.

- Mm-hmm.
- Perfect.

RICK: We certainly believe
there is something there.

Let's hope that this device
will provide those answers.

Absolutely.

- RICK: So, good luck.
- Let's do it.

NARRATOR: Later that afternoon,

while Jan Franke
begins to conduct

ground-penetrating radar scans

in boreholes located
in the Golden Egg...

BILLY: You can see the
third board there now...

CRAIG: Yeah.

BILLY: on the
bottom of that row.

RICK: Yep.

NARRATOR: Rick,
Craig and Steve

have rejoined other members
of the team at Smith's Cove,

where Billy Gerhardt
has just uncovered

more potential evidence

of the believed
man-made flood tunnel.

RICK: I mean, somebody
had to put those boards there.

It's a curious thing.

- What the heck is it?
- Yeah.

CRAIG: Billy.

Can you dump a couple
buckets on the wood

to try to clean it up a
little more around it?

(grunts)

♪ ♪

STEVE: There's a flat face

about six or eight
inches under it.

RICK: So, we are looking
at a structure that is

only partially exposed
in the moment.

We're looking for anything
out of the ordinary in the area.

And here we're seeing
something out of place,

but there has to be more.

I was hoping something
would show there.

CRAIG: Yeah, me, too.

- There she goes.
- RICK: Oh, yeah.

It's going more. Look at it.

CRAIG: Watch out.
There's a crack right there.

- Ooh.
- RICK: Oh, yeah.

Ooh...

That whole thing's going.

Wow. Wow. Wow. Wow. Wow.

- Ooh...
- The whole thing's going.

That whole thing's going.

Wow. Wow. Wow. Wow. Wow.

NARRATOR: It is a tense and
potentially dangerous moment

at Smith's Cove.

A section of the trench

that the Oak Island team
is excavating in search

of the legendary flood tunnel

has suddenly begun to cave in.

There is a board.
You were right.

That it, you see it there?

CRAIG: Yep. That's a big board.

RICK: We should grab that

- before we start digging, you know?
- BILLY: All right.

♪ ♪

Oh, there's a beam, too.

CRAIG: Look at that.

I don't think that's a board.

It's a rock, isn't it?

- CRAIG: Rock?
- RICK: Concrete.

- STEVE: Oh!
- CRAIG: Wow.

RICK: Look at that.

CRAIG: Oh, yeah.

RICK: See this?

It's not uniform
thickness. Right?

- Thicker here than it is here.
- CRAIG: Over here? Definitely.

This is where Emma is
gonna be incredibly helpful.

- Yes.
- RICK: She said she can,

you know, with
the different mixes,

- she may be able to define a decade or decades.
- Okay.

So...

We should just
leave it like it is.

NARRATOR: If the team can verify

that this concrete
was made in the 1960s,

it would likely mean
that it was created

by the Restall family
and that their efforts

to locate the believed
flood tunnel that feeds

seawater into the Money
Pit could soon pay off.

Let's take... let's go
take a look at that beam.

We found concrete and
then we find a huge beam.

It's evidence of work
by human hands.

It could represent
previously unknown work.

It's exciting.

There might be something here

that will speak eloquently
to what happened here.

That is one big beam.

I would think this would
be too massive for Restalls.

Oh, yeah.

STEVE: It doesn't look like
it's been cut by a machine.

-No. -STEVE: It looks hand-cut.

NARRATOR: A massive,
hand-cut wooden beam?

If the team is correct

that it wasn't placed
here by the Restall family,

could it be connected

to whoever created
the flood tunnel

and hid a vast treasure
in the Money Pit long ago?

When it caved in, it
sure looked like this was

the only thing, that
and the concrete.

Why those two
things by themselves?

There's no reason to stop

because you've got so
many unexplained things.

Yeah.

RICK: I think the
finding of the concrete,

certainly is highly suggestive
that we're in the area

of the Restalls' efforts to
block off the flood tunnel.

Unfortunately, the flood
tunnel eludes us at this point.

But maybe we are getting close.

There's a chance that we
may find more things today.

I think it's just a matter of
continuing what we're doing.

Keep digging.

RICK: Let's go find something.

♪ ♪

NARRATOR: The
following morning...

in the Money Pit area...

JAN: All right.

Well, let's take the
borehole radar out

- right now.
- Okay.

NARRATOR: Craig Tester joins

Dr. Jan Francke to assist him

while he scans another borehole

with his specialized ground
penetrating radar device.

We have a
transmitter on one side

and a receiver on the other,

and it's all fit
inside a tiny tube.

There's a computer
on board as well.

So we're gonna be logging
all the data inside the hull.

So we have two little batteries
that we're going to insert

and once we do that, it's
gonna start up the radar

and it'll be collecting data.

And then, we'll
have a little app

- that we can control it with.
- Okay.

All right. Let's go
ahead and put this in.

CRAIG: There's a number of
things that we might be able to see

that could tell us that
there's a flood tunnel nearby.

It could tell us if
there's a, you know,

a treasure nearby,
a shaft nearby.

Okay, this is the next
borehole we want to do.

- Okay.
- It's, uh, HN-16, it's called.

As you can see, the
Garden Shaft is right there.

NARRATOR: Located within
the so-called Golden Egg,

borehole HN-16 sets

just 18 feet north
of the Garden Shaft:

the 18th-century structure
where one year ago...

the team encountered
the possible flood tunnel

while conducting a
probe drilling operation

in search of the treasure

some 100 feet underground.

There's some theories that, um,

the treasure is hidden

off to the side in-into a tunnel

that was dug off from
the main Money Pit.

So if this can image

five, ten, 15 feet out or more,

it'd be fantastic.

Yeah, that's the idea
of a borehole radar.

So what we're gonna do is

insert this down slowly
and it's going to track

all the way down and look
all around the-the drill hole.

Okay. Let's get started.

The recording is all done

at the tool down hole...

JAN: And down she goes.

CRAIG: so we
won't have any idea

what the tool is
seeing until he can

download the
data and process it.

JAN: Okay. And downloading
data. And we got it.

CRAIG: But hopefully, we'll find

some indication

that the treasure is
nearby, indications of a vault

in the Golden Egg.

I don't know how far
out it's going to see,

but if we can see 15
feet, that would be great.

But let's see what we see.

CRAIG: Sounds good.

NARRATOR: Later
that afternoon...

MARTY: Hello, guys.

- RICK: Hey.
- CHARLES: Hey, Marty.

- TERRY: Hi, Marty.
- ALEX: Hey.

This is a very
interesting war room.

NARRATOR: Craig Tester,

along with Rick Lagina

and other members
of the team meet

in the war room as Marty Lagina

joins them via video conference.

RICK: We have here, probably

the most interesting find,

something that might corroborate

what the Restalls attempted
to do many years ago.

NARRATOR: They
have gathered to hear

a scientific report from
archaeometallurgist

Emma Culligan
regarding the large pieces

of concrete that were recently

unearthed at Smith's Cove.

This is indeed concrete
'cause concrete is

cement, aggregate and sand.

And this is a pretty simple
cement-concrete composition.

NARRATOR: Prior
to today's meeting,

Emma scanned the concrete

with an X-ray
diffraction device...

or XRD... which uses X-rays

to determine the
chemical composition

and physical
properties of materials.

What's really cool about it is,

in the XRD, I did get
a portlandite trace,

which kind of puts it in the
group of Portland cement.

NARRATOR: Comprised
of a combination

of limestone and clay or shale,

Portland cement is the most
common type of cement used

in modern-day construction.

It is often mixed with sand,

gravel and water
to make concrete.

There's only two locations

in Canada that have portlandite

and that's Quebec
and then there's B.C.

And this is most
likely Quebec-sourced.

All of the aggregates
and sand are most likely

Nova Scotia-based
'cause those are all

compositions that I normally
see in our soil and sand.

So there's a few
key things that can

narrow down a
date for this cement.

So the Quebec location started
hydraulic mining in the 1920s.

And this is
hydraulically-mined cement.

I don't think it's
anything post-1980s

cause it's missing
modern concrete mix.

So I can narrow it down to...

1920s to 1970s cement.

Because it's porous,

the aggregates are not
evenly placed throughout.

So it was rushly made. It
wasn't mixed thoroughly.

So it would kind of fit

the whole storyline

of, like, filling
in a floodgate.

This concrete could fit
the period of the Restalls

during the 1960s.

MARTY: I think you've found

where the Restalls
thought the flood tunnel was.

RICK: I think what
sits in front of us...

thanks to Emma

for corroborating that
this, indeed, could be

part of the Restall effort.

NARRATOR: In the war room,

Emma Culligan has just presented

scientific evidence

that the cement
unearthed by Rick Lagina

and the team at Smith's Cove

may have been used

by the late treasure
hunter Robert Restall

and his family in 1961

during a failed attempt

to seal up the
so-called Vertical Shaft,

an approximately 32-foot-deep,

1.5-foot diameter
stone-lined hole

believed to be connected
to the legendary flood tunnel

that feeds seawater
into the Money Pit.

Might this piece of concrete
offer critical evidence

that the team may be close
to locating the flood tunnel,

which could lead them

straight to the Money
Pit treasure vault?

CRAIG: They thought
that was the spot

to shut off the flood tunnel.

That's why they
wanted to cement it.

And they recorded it as having

a direct impact on
the flow of water.

So there was definitely

some sort of connection there.

Exactly.

RICK: Look,

I'm heartened by it.

The Restalls' understanding

of the location of
the Vertical Shaft

was very important to
them and it should be to us.

So having said that,

let's try to find
the Vertical Shaft.

So, this is our
Smith's Cove survey.

We're currently
sitting right here.

In that same area, that's
where we found the concrete,

along the projected
line of the flood tunnel.

And that's really
important to us because

it confirms that the flood
tunnel system is real.

And it confirms that
the Restalls were

in the right place.

We're following
a trail of clues.

And I think it's important

to continue this work.

So, I am heartened by this.

I think we're on the
trail of something.

So, the only way to do it

is to get back out there.

- Let's dig.
- Let's do it.

DOUG: Go, team.

- RICK: Thanks, Marty.
- MARTY: Yep. See you.

NARRATOR: The
following morning...

GARY: Wow, there's
nothing in here.

This is quiet.

At Smith's Cove,

Craig Tester supervises
the excavation

to locate the vertical shaft
and believed flood tunnel,

an excavation which experienced

a potentially dangerous
cave-in just one day ago.

CRAIG: Hey, Billy.

BILLY: Hey. So, my thoughts are

we just go further in the center

to see if there was any rocks.

CRAIG: Okay. Well, I'm
good with digging deeper

and see how it feels.

- Right.
- Yeah, we're going to weigh it

on the outside now,
just in case that caves.

- Okay.
- Yep.

CRAIG: I'm hoping we
can find a vertical shaft.

At the surface, it was just
a small mound of rocks,

and below that,

it was a rock-filled hole,

but it went down
a significant depth.

So, we're looking
for small boulders

as we're digging down
deeper and deeper.

But one concern we do have is

the sides might cave in.

So, we're watching out very
closely for safety purposes.

See the beam that
fell in in that corner?

BILLY: Yeah.

CRAIG: It is
still kind of in line

where Steve put that orange mark

for the potential flood tunnel.

BILLY: Yeah, it is
in line where that is.

CRAIG: Might be able to test it

and get some good
dendro dates off of it.

BILLY: Yeah.

NARRATOR: More wood planking,

found over 30 feet
below the beach?

Is it possible
that Billy Gerhardt

has just unearthed
another clue suggesting

that the flood tunnel
may be located nearby?

CRAIG: Any time we do
anything on Oak Island,

you never know what's
original and what's searcher,

and that's the whole key
is distinguishing the two.

So, anything you can start
dating helps us determine

the time frame of the
wood going in place

and if it's associated
with the flood tunnel.

We've got to keep going.

Every time we make a scoop,

- we're finding something else.
- Yep.

That's for sure.

NARRATOR: While
the excavation continues

at Smith's Cove,

near the shoreline of Lot 5

on the western
side of the island...

JACK: We're looking
for a continuation

- of this stone feature?
- MOYA: Mm-hmm.

Yes. I would like to see
how it follows that way,

which I think is what
Laird's plan was.

Jack Begley and
archaeologist Moya MacDonald

are proceeding with a
methodical investigation

of a large, rounded
stone foundation.

A foundation where the team

has uncovered compelling clues,

such as mortar-like soil,
matching other samples

that were collected
from nearly 100 feet deep

in the Money Pit area,

as well as a cut silver coin

and iron tools that
have been dated

to the 17th century.

We're not quite
down too far just yet,

so we could find something else.

Yeah?

These discoveries and more

have made the team
speculate that this feature

served as a staging ground

for whomever
constructed the Money Pit.

Now, they hope to
find proof that will reveal

just who the creators of
both features may have been.

This looks kind of cool.

Nice.

- Good find?
- Yeah, it looks like a...

like a bottle rim.

It's probably a wine bottle.

ETHAN: Oh, nice.

Yeah, we found
a large bottle base

- just over by those two trees.
- Okay.

MOYA: I haven't seen a top yet

as long as I've been
working on Lot 5,

so this is really interesting.

Great.

MOYA: Great start to the day.

JACK: Lot 5 has been
a horde of artifacts.

I think what happened on Lot 5

not only fits right into a
deposit in the Money Pit,

but I think they
covered over the area,

trying to hide it.

We're off to a good start.

MOYA: I think so.

Oh. This is cool.

Just popped out of nowhere.

Hey, Jack, do you
want to come see this?

JACK: Ooh. What is that?

JACK: What'd you find?

NARRATOR: While investigating

the large stone foundation

near the shoreline of
Lot 5 on Oak Island...

It looks like a
piece of strapping.

Archaeologist Moya
MacDonald has just made

a potentially
important discovery.

It's interesting
'cause it's bent at

kind of a 90-degree angle.

JACK: Now, "strapping,"

you mean like metal strapping

to keep a box

or a barrel together?

Yeah, it looks like it.

It's straight, so I'm
not too keen on saying

- it's from a barrel, but...
- So, maybe

- a small box or a chest.
- Maybe a small box.

Well, Laird had suggested

that there could be
some type of a cache

related to the structures
somewhere around here.

And maybe, that's a bit of

strapping to a box
as part of the cache.

'Cause we did find some coins.

Actually, a fair
amount of coins,

just right from this area.

- Yeah, that's true.
- Who knows what

they were keeping
in a box or a chest?

NARRATOR: Could
Jack's notion be correct?

Is it possible that this
piece of metal strapping

may have been part of a
chest that contained valuables?

If so, might the chest
have been moved

somewhere for safe keeping,

such as in the Money Pit?

Or might it be
buried even deeper

within this mysterious
foundation?

It will help define
the story a little better.

Yeah, figure out who
was actually here.

Yeah, we still don't
know, and their purpose

is unknown, too. I just think

it's treasure-related.

We had some really
good finds on Lot 5.

Buttons and coins
and the lead piece,

beads and ammunition.

We don't find the
type of artifacts

in such concentration

anywhere else on the island.

And so, it makes you wonder

could there be a hidden treasure

just right around here?

- JACK: Hey, Helen.
- HELEN: Hi.

- MOYA: Oh, hi, Helen.
- Hi, guys. How's it going?

- ETHAN: Good.
- MOYA: Well, we found

some interesting things
I wanted to show you.

So, first cool thing

we found so far has been

this bottle rim.

Yeah. So, this, the, um,

the paler olive glass,
should we say, um,

indicative of the
French wine bottles.

I think we had a
couple of pieces here,

like over in that unit, and
we've definitely had some

up at the other feature as well.

JACK: It shows that they were

in use at the same time,

since we're finding the
same artifacts in both features.

RICK: It's amazing,
the progress on Lot 5.

We have found
artifacts from England

and France, roughly from

the 1600s to the early 1800s.

That's incredibly intriguing

because I believe there was
an expansive effort over time

by groups, entities, to hide

something of great value.

And on Lot 5,

I think there's a richness now,

a much more complex
story developing.

So, we had that one,

and then we found

a piece of strapping

that we thought was
interesting 'cause it's kind of

bent in a 90-degree angle there.

HELEN: That may just be
damage from being in the ground.

It's hard to say.

So, I think if we took this back

and put it in the CT scanner,
we might be able to see

if this is cracked, which means

-it would have been
damaged -JACK: Mm-hmm.

Or if it was intentionally

- bent over.
- JACK: 'Cause if that is

an intentional 90-degree turn,

then it would be
on, like, a chest

- or some sort of a box.
- HELEN: Something like that.

Yeah, you know, the strapping
around the edge of it. Yeah.

JACK: If that is
some type of a cache,

this is the area

where we found a lot of coins.

It's possible.

I have known, like,
coins been found before,

like, you can find a
little stack of them.

Like, people will bury
them or sometimes put them

under floorboards, so they're
here around the outside.

JACK: What were they doing here?

And why did they choose Lot 5,

and the deeper
Money Pit soils, too?

And why dig such
a large foundation?

- JACK: Then bury it?
- HELEN: Mm-hmm.

It's why I think
there's another story

that we haven't uncovered here,

that relates to
the treasure hunt,

and maybe a
hidden chapter of it.

Yeah, yeah.

Okay. So, you guys are just

continuing down in this
gravelly layer right now.

Take this down as much as we can

and then try and
define this line of rocks.

- Mm-hmm.
- HELEN: Okay.

Keep going, find more stuff.

- That's all we can do.
- JACK: Yeah.

See you, Helen.

NARRATOR: As the
investigation on Lot 5 continues...

CRAIG: Hey, Billy.
Anything new down there?

There's still something
going on in this side.

NARRATOR: Craig Tester
and other members of the team

dig deeper near the
beach at Smith's Cove

in search of the vertical shaft

and the legendary flood tunnel

that feeds seawater into
the original Money Pit.

BILLY: You've
got the three rocks

and then, like,
there's a rock here.

Oh, yeah. Yeah.

BILLY: We got quite a bit of
water coming out underneath.

Small, quite a few cobbles.

But, I mean, you don't
normally see one, two, three,

four rocks, and then I pulled
a couple out from there.

There's something
going on there.

CRAIG: Yeah.

- Keep digging.
- Yeah.

CRAIG: As we found these
boulders, the question is

is it part of the
vertical shaft?

I don't know. I hope so.

You got to be patient, you
got to follow the process.

Um, you know, dig deeper.

Those rocks are interesting.

I'm not sure what
they mean, but...

BILLY: Me, neither.
You notice, a bunch more

cobbles, this size,

just rolled out from
underneath them.

That's pretty
odd there, I think.

CRAIG: Yep.

You know, everything
still seems to be

coming right under
the center line

that Steve put in there

for the potential flood tunnel.

You know, the Restall indicates

that original people put
that 18-inch vertical shaft

full with rocks in place.

If it was 18 inches in diameter,

with rocks, I mean, I
wonder if, down deeper,

it could be larger,

- like we're seeing there.
- Right,

- lined with boulders.
- Yep.

It could be it, it could
have been a vertical shaft.

The stacked rocks
allow the water

to transfer underneath it.

It could be the type of rock
formation we're going through.

Yeah.

NARRATOR: Is it possible

that the large stones

the team has just unearthed

are part of the man-made feature

known as the vertical shaft?

If so, that could mean
that they are on the verge

of locating and cutting
off the booby trap

that has stopped searchers
from recovering the fabled treasure

for more than two centuries.

I think somebody
stacked those in there.

CRAIG: Yeah.

BILLY: That's the
most interesting thing

we saw so far, right there.

- CRAIG: Gentlemen.
- SCOTT: Hey, guys.

RICK: Hey.

We're digging a hole.

- It's quite a hole.
- NARRATOR: After being alerted

by Craig Tester that
possible evidence

of a man-made flood
tunnel has been uncovered

over 30 feet below the
beach at Smith's Cove,

Rick Lagina and
Scott Barlow arrive

to inspect the potentially
historic discovery.

CRAIG: So, what we're
finding is, along this wall,

there's some rocks
that appear to be

probably below where, uh,

the boards were that we found.

BILLY: Each rock was
touching, you know,

like... it was, like, they were
stacked in, and underneath,

was quite a few
fist-sized rocks in there.

What do you make of it, Craig?

Uh, I don't know.

It was definitely odd,
'cause you look around

anywhere else and you
don't see rocks like that.

So, to me, it was man-made.

So, what... where
is the elevation

- where the stones were?
- BILLY: Right-right where the water

is coming in the trench there.

RICK: Oh, there, yeah.

Everything seems to be
lining up with that center line

that Steve put in for
the potential flood tunnel.

SCOTT: Yep.

Yeah. Nobody's dug more dirt

on the south shore
than you have.

What are those rocks
doing down there?

BILLY: Those
rocks definitely were

manipulated to
be there like that

- for... without...
- SCOTT: All in a row.

Yeah, I'm saying 110%.

I'll go more than 100.

RICK: Wow.

There's a whole
bunch of clues here,

- SCOTT: Yeah.
- We just got to put it together.

RICK: One wouldn't expect to
see boulders aligned like this.

There's a linearity to them,
which Mother Nature doesn't do.

If you confirm the
location of the flood tunnel

and project that line,

somewhere on that line
should be the original Money Pit.

So, it's exciting.

I firmly believe Restalls
were onto something

- with-with their work.
- I agree.

SCOTT: So, that's
why it's important,

I think, at this
point, not to stop.

If there's something here,

this is where
we're gonna find it.

If it really is a flood tunnel,

means there is a Money Pit.

Think of the laborious effort,

but more... even important
than the laborious effort

- is the plan.
- Mm-hmm.

A plan. A well engineered,
well thought-out,

very cogent application
of money, time,

material and effort

to do one thing and
one thing only, maybe.

And that's why this
story has endured

and that's why it continues
to be so fascinating.

Mm-hmm.

There's only one thing
to do. Keep digging.

- CRAIG: Okay.
- Yep.

NARRATOR: As Billy
Gerhardt digs for more evidence

of the believed flood
tunnel at Smith's Cove...

later that afternoon...

RICK: Welcome to the
war room, everybody.

Jan, welcome back.

I believe you have
some results in the...

- from your work in the Money Pit.
- Yes.

NARRATOR: Rick, Craig
and other members of the team

gather in the war room

with ground-penetrating
radar expert Jan Francke

as Marty Lagina joins
them via video conference.

JAN: Let's take
a look at this data.

NARRATOR: After
processing the data

that he collected from a
borehole known as HN-16,

Jan has created a visual
model of any anomalies,

such as potential
voids, tunnels or objects

in the so-called Golden Egg,

where high-trace
evidence of precious metals

were previously detected

between 80 and
120 feet underground.

So, what we're looking
at here is the radar profile.

It seems that our
last good reflection

is at about 12 feet.

Okay? So, we'll call that
the-the approximate distance

that we can get
away from the hole

- and still see something.
- RICK: How far are we

- from the Garden Shaft?
- Probably 18 feet.

JAN: Right, so,
when we're looking

at borehole radar results,
we're looking for anything

that really pops out.

As we scroll further
down the hole,

- we get this.
- RICK: Mm-hmm.

JAN: And that target,
absolutely, is characteristic

of a discrete void space.

- Wow.
- RICK: How far down are you here?

That's around 127
feet from the surface.

NARRATOR: A discrete void?

Meaning that some
kind of open cavern,

structure or container

appears to lie buried 127 feet

underground in the Golden Egg?

If so, might it be the
source of the precious metals

that have been detected
through groundwater testing

at that same approximate depth?

If you look on the screen,

you see this
upside-down horseshoe.

And that tells us
it's a discrete target,

- an individual target.
- Oh.

This is something
that is sitting

about three or four
feet from the borehole.

Now, we have nothing to
compare it against, right?

But it seems, just
from experience,

that we do see some
ringing, or reverberations,

which suggests that
it's probably full of water.

So, it could be a tunnel
or even a flood tunnel?

Probably not.

It's not salt water

because it's such
a strong signal.

If that was salt water, we
would see a shadow zone.

- Okay.
- Yeah. Right? And we don't.

We see really good
penetration through that,

- so that tells me it's probably fresh water.
- SCOTT: Okay.

- JAN: Yep.
- MARTY: And it's about

three to four feet away
from that hole, yes?

Uh, well, it's a little hard to
tell exactly where it starts,

but let's say three
feet on average.

And it's not a layer of geology;
that would look very different.

This is a target, so
it-it's a discrete object.

So, this could be the
fabled offset chamber.

JACK: Really?

- JAN: Sure.
- (laughter)

JACK: That's awesome.

MARTY: This could be
the fabled offset chamber.

Uh, and nothing would
make me happier than that,

even if you dig it
up before I get there.

- (chuckles)
- TERRY: Hear, hear.

NARRATOR: It is an exciting
moment in the war room

for Rick, Marty and
the Oak Island team

as ground-penetrating
radar expert Dr. Jan Francke

has just revealed that an
open void has been detected

at a depth of 127 feet

in the so-called Golden Egg,

the same region where
recent groundwater tests

have identified high traces of
gold, silver and other metals.

MARTY: Does anybody
in the room know

of any searchers who were
messing around at that depth?

No. Nothing in that area.

MARTY: So, it's pretty
exciting. I mean, I don't know.

Jan, I hope you're
right. I don't know.

- How right are you?
- (chuckling)

I can only show you what's,
uh, it says on the screen here.

There is a discrete target here.

I think we just widen the hole
and send Jack down there.

- (laughing)
- Yeah! Let's do it.

MARTY (voice-over):
All of the sudden, we have

a new piece of data,

a possible void.

It might mean that
we're close to evidence

of the original deposit.

So, am I excited this
could be the year? Yes.

Well, what are we
gonna do then, guys?

Are we gonna drill another
one right near there?

- What are we gonna do?
- First, I'll make sure

that Dr. Spooner has finished

collecting his new
groundwater samples in the area.

Yes, definitely.

CRAIG: Well, I think
this is great results.

I mean, the tool's
definitely working.

- We're finding a void.
- MARTY: Absolutely. Hey, look,

we started this year
and I was super hopeful

that the water analysis
would really narrow down

where the metals
are coming from.

You know, we got the
Golden Egg, which is very cool.

And now, if this is correct,

it's about as narrowed
down as it can get.

Within a three-foot radius?

We've never had
anything like that.

RICK: I think Jan well and
truly believes in his analysis.

Look, the man has
done this work, literally,

across the globe and
h-has had success.

This area in particular
is underexplored,

or underinvestigated at depth.

The water sampling program
has indicated metals on the area.

So, there's a lot of
reasons to be hopeful.

Look, uh, how... If
anybody around the table

is disappointed in
a legitimate target,

uh, then, we all
need to go home,

- right?
- (chuckling)

And maybe this discovery
will allow us to go home.

So, you know, let's
develop a strategy

by which we can exploit
this possible target.

It's all good news. We've
just got to stay the course.

So, Jan, again, we
want to say thank you.

- And, uh...
- Thanks for having me out.

Get out there
and start drilling.

- Can do.
- Let's do it. All right.

- See you, Marty.
- See you, Marty.

MARTY: Go get
'em, guys. Go get 'em.

NARRATOR: As another week
comes to a close on Oak Island,

new potential avenues
have been opened

that may lead Rick,
Marty, Craig and their team

to the ultimate discovery.

After identifying a massive
source of possible treasure

more than 100 feet deep
in the Money Pit area

and placing an X on the spot

where it has remained hidden
for more than two centuries,

is it now just a matter of time

before Oak Island's secrets
are finally revealed?

Or might a mysterious

and deadly line of defense

that is much more powerful
than a man-made flood tunnel

stand in their way?
