Tonight on
The Curse of Oak Island...

Oh, wow. Check that out.

That's a great find. That
could be really, really old.

This was used
to build a wooden vault

or some sort of structure
down below for safe keeping.

You've got something big
on your hands.

It's absolutely intentional.

It matches Lot 5
and the Money Pit.

And they were trying
to conceal it.

Which makes it
even more spectacular.

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.

You know
what time it is?

Treasure time.

A new day
on Oak Island

begins with great excitement
for Rick, Marty, and their team

as they are digging
to historic depths

in the Money Pit area.

We're right
at the bottom of Karma.

We're in the solution channel.

That's where
the treasure's gonna be.

Look, we've got
as good a chance as any

to find it today.

And I hope it's gonna be
right over there.

One day ago,

after excavating
the seven-foot-diameter shaft

known as Karma-1
212 feet deep

to the bottom
of the solution channel,

the team lifted the steel
caissons to allow loose soils

and debris to settle overnight
into a pile below.

They are now about
to retrieve those materials

with a dig bucket
and search them for evidence

of a large source of silver,

which has been detected
through water

and soil testing in this area.

It is their hope that
the silver is connected

to the 14th-century
Portuguese coin

reportedly retrieved
from the Money Pit

by foreman James Pitblado
in 1849.

All right.
Let the sluice loose.

Let's go take a look.

All kinds
of man-made things

are in that solution channel.

We've proven it.
We've brought them up.

So, I'm very hopeful that
we're gonna find some evidence

of the treasure that we think
fell into that collapsed area.

Nope. No hits.

Billy can get it all
in the truck,

- get it down to the wash plant.
- Yeah.

- See what's in here.
- Okay.

As Rick, Gary,
and Terry wait to search

more spoils
in the Money Pit area,

some 500 feet to the east,
near Smith's Cove...

- It's pretty muddy.
- Yeah, a little bit.

...Charles Barkhouse
and other members of the team

are at the wash plant,
searching by hand

through spoils
that were previously removed

from the Karma-1 shaft
and may contain

important evidence
or valuables not found

by Gary's metal detector.

This process has already
produced finds such as

a small, hand-forged iron chain.

It's a type of chain
Gary has previously found

while metal detecting in Europe,

and he believes could've been
used to lock a box or a chest.

Oh, wow. Check that out.

Look what I found.

Looks like
a rosehead spike to me.

And it's hand-wrought,

to fasten different pieces
of wood together.

That could be
really, really old.

Any time the team finds
something on the conveyor belt

at the wash plant,
I mean, we're excited.

But finding that rosehead spike,

you know, in Karma-1

could be the indicator
that we're looking for.

This could come from
the 1600s, or earlier.

This could be from
the original workings

of the depositors
of the treasure.

That's a great find. That's
gonna go to the lab, for sure.

Have Emma test that.

We'll keep looking.

Meanwhile,
back in the Money Pit area...

All right. This is it.

Looks like the last material.

- Let's check it out.
- Let's give it

- one more go.
- Okay, mate.

...Rick and the team
continue to search through

the final spoils retrieved from
the bottom of the Karma-1 shaft.

Think we've gone as far
as we can go. - Are you done?

- Yeah.
- So,

got one more chance
down at the wash plant.

Yep.

- Wash plant it is.
- Yep.

- Hey, guys. -Hey, there.
- How you doing, Adam?

Are we on bottom?

We're on bottom,
and we're cleaned up.

And bottom is?

- 212.
- Miss by an inch,

- miss by a mile.
- Yeah, well,

we're not gonna miss
the next time.

- Nope.
- Nope.

We didn't find it.

We just move on
to the next location.

- Yep.
- Literally,

our Top Pocket location

is the one we're about
to move to. -[Billy] Right.

Yep.

Find some treasure, boys.

Two weeks ago,
the team began excavating

a shaft, known
as Top Pocket Find,

located less than ten feet
northeast of Karma-1.

This shaft was positioned
directly over an area

where water testing had revealed
a massive source of silver

deep underground,
making it their primary target

for exploration
of the solution channel.

That doesn't sound
very good.

But unfortunately,

at a depth of just 25 feet,
the caissons

were stopped by gravel backfill
from a previous dig.

Now, using ROC Equipment's
powerful rotating oscillator,

the team from SB Canada
can resume digging

the TPF shaft
down to the solution channel.

On the one hand, Karma-1
is a little disappointing.

But you just
keep moving forward.

The quicker we get started,
the quicker we get down.

- Yep.
- Right.

Thank you. Appreciate it.

While the dig
proceeds in the Money Pit area,

later that day...

- Hey, guys.
- Hey. -[Fiona] Hi.

Every time I look at this,
I don't know what to make of it.

It's getting incredible.

- It's really quite spectacular.
- Yeah.

...Rick and Peter
arrive on Lot 8

to check on the investigation
of the cradle-like formation

of stones that were found
beneath a 40,000-pound boulder.

How in the world was that made?

It's a 40,000-pound boulder.

If you were to drag it in,
it would destroy this.

- Yeah.
- I'm not thinking about

how they did it
as much as the why.

I mean, this was
definitely purposeful.

We didn't remove any soil
from down here whatsoever.

It was filled with rocks.

After removing
the boulder revealed this

mosaic-like stone feature,

archaeologist Fiona Steele

has begun removing debris
and some of the stones

to determine what purpose
it might serve.

Especially since the team
has already detected

possible evidence of a shaft

and even silver
in the soils below it.

I've worked with stone
most of my life.

And the labor that you see,
uh, in front of you, is...

it was quite laborious.

It meant something to someone.
I think we need

to do as much work as possible

to address one key question:
what's underneath the boulder?

We had a lot
of smaller rocks,

the ones that are these size,
all in the center,

and they were very loose,
so once

I started removing them,

I started seeing
these other rocks underneath,

and you can see
the ones underneath

are a fair bit larger
in size than the ones

that were actually on top.

And they extend
all the way down here.

Hmm. -[Fiona] This is
what's starting to

produce itself as we've
been excavating here.

I will say this, that one there,

when I look at that,
the way it's positioned...

Coming this way.

It-It's a very curious
positioning of that.

Yeah. I still can't get it
out of my head,

the shape of these boulders

that we had,
which were very triangular.

We had this big one down here,
and we had

another big one there
and a big one there.

And it almost felt like
there was a triangle

pointing down to this boulder.

I mean, when you think
about this area,

you think about Zena's map
and the December Triangle.

This could
also be related to that.

In 2016,

the late author and researcher
Zena Halpern

shared documents with the team

believed to have been created by
members of the Knights Templar.

One was a 12th-century map
of Nova Scotia

and the other was
a map of Oak Island

possibly dating back to 1347.

Astonishingly, it featured

several locations
written in French,

but when translated to English,

they marked known sites
on the island,

such as the Money Pit,
the Swamp,

and a site called
the December Triangle.

Could the stone cradle
and boulder

align with a location
on a possible Templar map?

I've puzzled about
whether or not

this area could be referencing

the so-called December Triangle
on Zena's map.

I think we have to have
a really proper look

in the area in the vicinity
of the stone

and see if there's
more information to be revealed.

That will help us understand
the relationship

between the drawing
on Zena's map

and this megalithic
stone structure.

I came across
this area here

of a blue-like clay,

and you can clearly see
that there are chunks

of-of charcoal-like material
mixed in with this clay.

I'm just not convinced
that this

blue, um, gray clay
is natural to this area.

Clay like this
could be very similar

to the clay that we find
at the Money Pit.

I'm absolutely
mesmerized by this,

this blue clay.
I wonder if this is very similar

to the clay from the Money Pit.

On Lot 8,

after removing
some of the stones

from the cradle-like feature

that was covered
by the massive boulder,

Fiona has made a potentially
important discovery.

If you look at the way
the stones are--

now, I've removed a few--

but it-it really looks like
this clay material

had been used to mortar in
kind of a-a rounded section

in the front of it.

It's absolutely intentional
and purposeful,

and they were
trying to conceal it.

- And we did find some on Lot 5.
- Yeah.

- Makes it even more interesting.
- Yeah. Yeah.

Yeah, so if this matches that,
then, again,

more-more connections.

In 1804,
the Onslow Company

carried out the first
large-scale excavation

of the Money Pit and encountered

wooden platforms every ten feet
down to the 90-foot level.

During the dig,
they also reportedly found

a thick layer of hand-worked
blue clay at the 40-foot level,

which they believed
was used as a sealant

to keep water out of the shaft

in order to protect something
buried deeper below.

Curiously, in recent years,

the team has discovered
hand-worked blue clay

in the swamp,

and in the round feature
on Lot 5.

If Fiona is correct that
she has now found the same kind

of blue clay material
in this stone feature on Lot 8,

could it be more evidence
that this feature

was created to hide something?

This could be anything.

The reality is
there are lead and silver

beyond baseline values
within the structure itself,

possibly in association
with a shaft or a tunnel.

So, we have to be patient
at this point.

This has to be driven
by the archeological process.

Is there anything
we can do with the clay? -Yeah.

We'll get a nice big chunk
of that soil

and then take that
back to the lab.

And then, we can run it through
the XRD and see if it matches

the Lot 5 till
or the Money Pit till.

- That's where it gets fun.
- That's where it gets fun.

All right.
Let's get the sample done.

There, that's a good sample.

I'd like to give you
this little bit here.

We'll need
to get that to the lab

- as soon as we can.
- There's a "why" here,

and hopefully, we can
figure out what that is,

but I'm sure you'll
get to the bottom of it.

But let's keep
moving this forward, because

we want to understand it,
what it may mean.

- Yeah. -Yeah.
- We've got a plan.

- Thank you. Appreciate it.
- All right, see you guys.

The next morning...

Is that the first can?

Yeah. Just started.

If we're gonna find
some top pocket finds,

it's got to be this can.

...in
the Money Pit area,

Rick joins other members
of the team

as the TPF shaft
is once again being excavated

in a location where the
highest trace evidence of silver

has been detected
more than 200 feet deep

in the solution channel.

Our first 150 feet is gonna be,
you know, pretty benign.

But from there on,
it's everyone on deck,

and everyone
keep their eyes peeled.

Below 150 feet,
everything's open game here.

Because the solution channel

ranges between some
150 to 220 feet deep,

where the team believes
the treasure has fallen

after the collapse
of the original Money Pit,

it may take several days
before the dig

reaches its target depth.

Yeah, we're gonna
have backfill out of here

down to about 150 feet.

We are in the area
where there is

evidence of deep collapse.

The area where we have
retrieved significant items.

So I'm hoping, of course, that

this Top Pocket Find location
will provide the answer.

We all look forward to getting
down to the bottom here.

- This is the one.
- I sure hope you're right, Gary.

The Pitblado coin

strongly hints that
something is down there.

And at the end of the day,
we can

make this happen, and we will.

We've just got
to stay the course.

We're just gonna chew through it

until we get to the treasure.

- All right. I'll be back.
- You'll see it, mate.

- Thank you, guys.
- See you, Rick.

All right, mate.

Later that day...

- Morning, guys.
- Hey.

- Hi. -Morning.
- Morning.

So, we have Charlotte Wheatley
here in the war room.

...in
the war room, Rick,

Craig, and other members
of the team are

meeting with researcher
Charlotte Wheatley.

Charlotte,
she has some new information,

and I think today should be
exceedingly interesting.

So, having said that, Charlotte,
welcome to the war room.

Thank you very much.

In light of
a possible connection

between the Lot 8 feature

and Zena Halpern's believed
14th-century Templar map,

Charlotte, who is
a colleague of Emiliano,

Judi, and Corjan Mol,
has been studying the map

to look for more clues that may
help verify its authenticity,

and how it may help solve
the treasure mystery.

I came across this information

after researching the Zena map,

which I've done
four years' research on.

I examined every name and place
recorded on the map.

And one of them
I found quite interesting.

I'd never heard it before,
was Le Lionceau de Talmont,

which means
"the lion cub of Talmont."

What was interesting
for me is how

could Talmont connect
to the island?

There is a place in France
called Talmont-sur-Gironde, so

Talmont-sur-Gironde is
on the west coast of France.

It is a small fishing port.

One of the nicest features
of Talmont is a beautiful

medieval church,
and it's dedicated to

a lesser-known female saint
called Radegund.

It's got a very simple interior,
typical of Cistercian influence.

It was built in
the 11th or 12th century

by Benedictine monks.

The Benedictines are
a Catholic religious order

that was founded
in the sixth century,

and adhered to what was known as
the Rule of St. Benedict,

a moral code for leading
a faithful and productive life.

These writings
inspired the formation

of an order of monks known
as the Cistercians in 1098.

And one of their
most noted leaders

was Bernard of Clairvaux,

who co-founded
the Knights Templar in 1119.

The church was fortified.

So that actually meant
that they used it

not only as a church
but also as a, as a fort,

which is not a common thing
on churches in France.

How is this connected
to Oak Island and why

the Lionceau de Talmont,
the lion cub of Talmont?

Really interestingly, there
used to be a very intriguing

feature that
resembled the Sphinx

and was actually known
as the Sphinx of Talmont.

And as you can see,
it is a Sphinx-like shape.

Sadly, um, it was destroyed
in the early 20th century.

So, there's nothing left today?

There is nothing left.

And the church itself
used to overlook the Sphinx,

so it makes sense that this
could actually be the...

- the lion cub of Talmont.
- Oh.

So, what interested me
is that the church itself,

it actually used to be
pointing towards where

the Sphinx was, at roughly
a 292.4-degree angle.

And when you follow
the line of the church,

going through
the front door and continue

on a straight line,
and you go across the Atlantic,

- you end up on Oak Island.
- Hmm.

If that was one coincidence,

that's fine.
What gets quite creepy is that,

about 60 kilometers away,
I come across another chapel,

which is located in a place
called Courant,

and it is also dedicated to
the same saint, Saint Radegund.

The church itself is at
an angle of 292.1 degrees,

and when you follow that line
from the back of the church,

in a perfectly
straight direction,

you arrive on Oak Island.

Whoa.

And again, this church
was built by the same people

who built the other church.

And in between both churches,

there is another
Radegund church.

And this is actually located

in a town of the same name
called Saint-Radegonde.

And it's oriented
at a 292.1-degree angle.

So, if you follow the axis

of the church in a perfectly
straight direction,

we arrive again on the island.

It's odd, for sure.

So,
we have three churches

under the same patronage,

built by the same
group of people,

located in a 60-kilometer radius

all on the west coast of France.

These three churches are
pointing towards the island.

It's interesting.

are pointing towards the island.
e ts

So, three points,
dedicated to the same lady,

built by the same
group of people.

In the war room,
researcher Charlotte Wheatley

is presenting new information

about three potentially
Templar-related churches

in the region of Talmont, France

that she believes are located
on a east to west line

that leads directly
to Oak Island.

It just can't be coincidence.

I have tested this theory
on lots of churches in France,

and this doesn't happen.

So, I've asked other
researchers to check

if the alignments seem correct,

and they all agree
that these three buildings

seem to be perfectly aligned
with the island.

Talking about,
when was that built?

Same period.
We're talking about 13th...

- 12th, 13th century. Yeah.
- Yeah, so...

- It's curious.
- It is.

The alignment
Charlotte mentions,

that's incredibly curious.

Were the alignments
with the churches purposeful?

There, perhaps, are alignments
that we are currently

unaware of with other
features on the island.

Lot 5, Lot 8,
the bog, the Money Pit.

Is there a connection here?

So, I decided to
take a look at the actual

patron of these churches,
Saint Radegund.

She was born
around the year 520.

And she actually wanted
to dedicate her life

to becoming a holy woman.

She made a monastery,
and she turned it into a sort of

place of learning,
prayer, and pilgrimage.

Born into a royal
family in the German land

of Thuringia,

Radegund became
a devout Christian nun

and emigrated to France,

where she founded the
Catholic Abbey of the Holy Cross

in the city of Poitiers
in 552 AD...

...a sacred site which
reportedly houses a piece

of the so-called "true cross"
on which Jesus was crucified.

And this is the thing
that really got me,

is that, when I did research
on her, I noticed

that she's known
to carry a book.

And she's known to carry a book
with a four-dot cross.

I've looked at lots
of iconography of saints.

This is the only saint
I've found who's presented

with a book
with a four-dot cross.

In recent years,
the team has visited

numerous former strongholds of
the Knights Templar in France,

Italy, Denmark,

and Portugal.

What'd you find, Pete?

I think something
pretty interesting.

Oh. -[Narrator] And in
each location,

they have seen prominent
carvings of crosses surrounded

by four dots...

We have
the four-dot cross there.

- Mm-hmm.
- Oh, wow.

...that some experts
have interpreted to signify

where the Templar order hid
sacred, religious treasures.

Curiously, that same symbol
was found by searchers

on the so-called H+O Stone
in 1921 on Oak Island.

Has Charlotte found new clues
on Zena Halpern's map

that may help verify
a true connection

to ancient Templar-related
sites in Europe,

and suggest it may be a key
to locating where something

of great or sacred value
lies hidden on the island?

The, uh, H+O Stone

that had the, uh,
cross with the four dots,

I'm just wondering if continued
research on that end

can also tie those symbols
with those churches.

Yes. And I think maybe
that's worth looking into.

If the connection that
you're suggesting does exist...

Mm-hmm. -...then the map does
have a piece of information

that is connected,
possibly, to Oak Island.

That's right, yeah.
So, it is possible,

and it needs
further developments. -Right.

It would be interesting
to have a look on the island.

Maybe there's another
H+O Stone out there.

That's fair. Yeah.

But the question is,
what happened here?

I don't know. I'm gonna say
the biggest mystery

in the universe,
isn't it, really?

I would like
to think what happened here,

that this is a sacred place,
and it was chosen

for a reason, and I

obviously hope
there's something buried here.

And I hope
you're gonna find out.

With your help, we will.

We say thank you.

Thank you.
Thank you very much.

As a new morning
dawns on Oak Island...

Here we go.

- We're moving on down.
- Yeah.

We got another load coming up.

...in the Money Pit
area, Gary, Terry, and Jack

continue to monitor the dig
in the TPF shaft.

We're slowly nearing
the zone of interest

in Top Pocket Find 1,

and I'm very hopeful
that we're gonna find

clear evidence of the collapse
of the Money Pit

and find something
really valuable

down in the solution channel.

Ah.

Oh, what the...?

Stop.

It's caving.

Geez. There's material
flopping in.

Because the ground
has suddenly

begun to give way
around the TPF shaft,

the team from SB Canada

and ROC Equipment will need
to move the oscillator

to find out if they can safely
continue the excavation.

Wow.

This is not good.

We felt
the ground shake,

and you can see

that the ground around
the oscillator has given way.

There's been a collapse.

- Hey, guys.
- Hey, mate.

Holy cow. It looks like
we might've lost ground.

Did we? -[Adam E.] Yeah.
We're losing stuff

down below.

Wow.

We're losing
stuff down below.

In the
Money Pit area,

after reaching a depth
of some 105 feet

in the TPF shaft,

the surrounding earth
has suddenly begun to cave in,

meaning a dangerous collapse
could follow.

Going at this depth,

it's a lot of wear and tear
on everything. -Right.

There's a ton of friction,

there's a ton of stuff
in the ground.

Like, we've seen settlement

on the outside of the casing.

We did see from the table

- the can was a little bit shaky.
- Yep.

It's more of settlement

from all the other work
that's been done around it,

and the lighter material
goes down

as we agitate all the way down
with the oscillator.

It's dropping all that
material through... -Yeah.

...the bigger holes and slots.

I remember the last time

there was a collapse
in this area.

It looks the same.

Last year, the collapse
went straight down

the side of the casing.

You know,
it was running full depth.

- Hey.
- We got a problem?

We're having caving.

One year ago,

the earth surrounding
the TB-1 caisson,

located less than 20 feet
to the northwest,

suddenly began to cave in,
and for safety,

the team had to abandon
the excavation of the shaft.

Now, SB Canada and ROC Equipment

must act quickly to prevent
a larger collapse

and allow the team
to keep digging

where they have found the most
compelling evidence of treasure

in the solution channel.

This is only about ten,
12 feet up from the top.

So, perfect time
to build it back up.

- We're backfilling.
- That will solve that?

Yep. Yep, that'll tighten it up.

You got large diameter,
solid metal tubes

being driven down
into the ground,

and we've got
a lot of activity going on

where, basically,
we have some cave-ins.

These types of things,
they create a lot of havoc.

There's material moving

in and out and away from
the actual caisson itself.

We have to, uh, mitigate those,
we have to push material back

down into the hole
because it's collapsed down in

and around the caisson
as we're pushing it down.

Now we've got this
stabilizing everything

from 108 all the way up.

So, I see we're gonna
pack a little bit

around it right now
and then we move on, right?

Yeah. We're getting
ready to transition between

the bigger casing
to the smaller casing.

Okay. Good. -[Adam E.] So,
it's telescoping time now.

Essentially, you know,
to avoid the problems,

we're splitting the hole
in two, right?

Right. -[Adam E.] Half
the bigger casing

takes the top half out.

22 goes in, finishes it off.

What's the reason for changing
to a smaller caisson?

See the material
that we're going through?

We're going through hundreds
of feet of this stuff.

So, it relieves
all that tension.

Yeah, whatever it takes
to get down there.

Whatever it takes
to get down there. -Yeah.

Once SB Canada
fills in the collapsed areas

around the eight-foot-diameter
TPF shaft

with gravel backfill,

they will continue the dig
down to the solution channel

using smaller,

seven-foot-diameter
steel caissons.

This will safely allow them to
dig below the collapsed region

and reach their target depth.

Anything and everything
to ensure that we're gonna

- get all the way down to 220.
- That's the goal.

- Whatever it takes, right?
- Yep. -Yep.

Get down there. Get deep.

- Find Gary's treasure.
- I love it.

See some of those
top pocket finds.

When we get
caissons down

very near the solution channel,
things start to collapse.

I've seen it. I've seen it
collapse and collapse again.

And every time,
it was when we got close,

when we got close to the bottom.

So, that's why I think

it's entirely possible
that's where a treasure fell to.

So, we absolutely have
to get to at least

220 feet on all of these.

Yeah, it looks like
they're almost done.

So, why don't we head back
to the table?

- Yeah.
- Sounds good. Yeah.

- See you guys later.
- Thanks for the update.

- Absolutely.
- Rock on.

As the dig
operation proceeds

in the Money Pit area...

Hey, Carmen.

Appreciate you stopping by.

- You got something to show me?
- We do.

...in
the Oak Island lab,

Alex and members of the team

are meeting with blacksmithing
expert Carmen Legge.

They have invited him back
to examine the rosehead spike

retrieved from the Karma-1
spoils two days ago.

Carmen, this spike was
found by the wash plant team

in the spoils
of the Karma-1 caisson.

Emma, you have some analysis
of this spike?

Compositionally,
it's a kind of unique iron.

What's unique about it

is that it has an exceptionally
high phosphorous content.

So, I categorize it
as cold-short.

Meaning it's brittle
in colder climates. -Mm-hmm.

Cold-short or
cold brittle, it's when an iron

has a high phosphorous content,

which affects its strength
in cold climates.

Cold-short iron is a great
indicator for an iron age

because now, in modern times,
we can control the effects

of phosphorus, as it's a trait
that we just don't want.

Um, it does have some
trace amounts of manganese,

but even higher amounts
of sulfur,

so it's a weird mixture

within a composition,

so the most likely date

is mid-1700s at least.

Wow.

So, Carmen,
what can you tell us?

Well, it's
a square-shanked spike.

I'm gonna say it was probably

five or six inches long
originally.

It's hard to see
the head on this,

but it looks like
it was very crudely made,

it doesn't have any form to it.

Uh, what does it show
on the scan there, Emma?

Oh, it's just
basically smushed down.

- Deformed.
- Mushroomed. Yeah.

But it's not formed.
It was driven straight down,

and the fibers are all
split out like a mushroom.

This is a piece
of something larger,

and they took it
and drove it into something.

Mm-hmm. So, probably
the reason they reused it

is 'cause it broke.

- So, an improvised spike.
- Yeah.

I think they reused it and
just smashed it into something.

And this came from where?

We do know for a fact
it came from below 167 feet.

So, to me, that means
that it's deeper than any

searchers have reached.

Especially in that area.

Which makes it very interesting.

Yeah.

These are typically used
for planking, you know, uh,

not for the main structures
of anything, but oftentimes when

they were making
large boxes or vaults.

That leads me to think
that this was used

to build a wooden vault
or some sort of

structure down below
for safekeeping something.

that you would see,
[Cg

oftentimes when they were
making large boxes or vaults

for something they wanted
to, um, uh, keep safe,

something valuable
they wanted to keep safe.

- That'd be good.
- That is what we're looking for.

In the
Oak Island lab,

Carmen Legge is examining

a potentially
mid-18th-century spike

that was recovered
from nearly 170 feet deep

in the Karma-1 shaft.

If this is something
that was reused...

You know, any effort
here on the island

was obviously done in secret.

If there was a deposit made,

they had to use
what they brought,

and this is sort of
speaking to that.

Emma,
is there enough wiggle room

in that early date

- to include 1746?
- Absolutely.

Well, that's interesting
because that, uh, allows

for the possibility
of the Duc d'Anville.

Because we're talking
about one ship

that got separated
from the main fleet... -Yeah.

...then decided
it most prudent to

bury what they were carrying

so it didn't fall into
enemy hands. -[Alex] Mm-hmm.

So, they would've had
to work with what they had

on that one ship.

Could Doug
be correct that

the team may have
found a new clue

linking possible buried treasure
in the Money Pit

to the Duc d'Anville,

an 18th-century French noble
whose family had links

to the Knights Templar?

In 2017, Doug found
part of a ship's log

in the Nova Scotia archives

that described
the burial of treasure

in a deep pit on an island
in this area

back in 1746.

The log was reportedly written

by a crew member under
the Duc d'Anville's command.

This little spike
is maybe telling us that

our theory about the collapse
is correct,

and that we're close

because we're picking up
traces of something

from the original Money Pit.

So, we would be then
looking at just remnants

of things that didn't make it
all the way down there

in a collapse.

So, even though we didn't
hit the treasure in Karma,

finding this spike tells us
that we were close.

- Yeah.
- The hope is,

if it is something
from the Money Pit,

if it is something
from a chest or a box,

to me, it speaks
to the possibility that

other things will be found.

That could be the source
of the silver concentrations

that are indicated
by the soil samples

and the water samples
at this location.

And hopefully,
there's something down there

in Top Pocket Find 1.

It's very interesting.

So, you know, thank you both
for your analysis.

I think it says
we're on the right track,

and we need to keep going.

So, that said,
we will try to bring you guys

some more to look at.

Very good.

- Thank you.
- See you later.

Later that day...

...while the excavation
of the TPF shaft continues

in the Money Pit area...

How's it going?

Hey, Rick.

We just lifted
a couple more rocks.

Right.

And under those rocks,
we're getting organics.

- I got to get down there.
- Go for it.

...Rick joins Jack
and the archeology team

as they continue excavating

the cradle-like formation
of stones on Lot 8.

- No idea how deep? Yet?
- No, not yet.

No, but it's giving us
a reason to keep going.

So, we're gonna try
to expose the base

and then work our way up
to see how it was built.

Do you think what you're calling
the second level,

is that natural?

Or are those placed as well?

No, I think they're-they're
still all placed.

Right now, this seems
to be... firmly affixed.

I can't get it out. -
We're all curious, you know.

I can give it a try. I'm not
saying I can do it, though.

- What's und-- What's under it.
- Yeah, yeah, yeah. Absolutely.

You come this way.
I'll go that way.

I'll disturb those.

Oh, no, that one's there.

Oh, there's no give to that.

That's amazing,
they are locked in there tight.

Lot 8 presents all kinds
of possibilities.

One of which has to include that

Zena's map may have
some relevance here.

Oh, boy. That's in there.

Whether because
this construction

was some sort of alignment,

or maybe there's
something under there.

We need to figure out what
this construction represents.

Oh, wow.
That is definitely in there.

Yeah, I think that's in
there. I think that could be

redeposited and it's just...

- I think it is.
- ...it's embedded.

Now I really want it out.

They're fixed in there
quite tight. -Yeah.

Scrape this stuff.

Yeah, it almost looks like
some sort of hard clay.

Yeah, it's, uh...

I would put a little chunk
like that in some water

and see what its consistency
turns into. -[Jack] Hmm.

yeah. -[Rick] We might
be able to reconstitute it,

- as it was used.
- Yeah.

You have
a little water there, Jack?

- Yeah.
- See if it turns into anything.

Okay. Thank you.

Is it turning into,
like, a clay?

More like a...

Almost like, almost
a little bit like cement.

Yeah, no,
that looks like cement.

- Cement.
- Yeah.

This is unbelievable.

like cement. -[Rick] Yep.s

That's why this held. Right?

- Yep.
- And this is just

- all filled in.
- Mm-hmm.

- That's what you see here.
- Oh, yeah.

On Lot 8, Rick has
just discovered evidence

that the stones
which were uncovered

below the massive boulder

appear to have been set in place

with man-made mortar, or cement.

Once it dries, I bet that
adheres perfectly to that.

- Really gritty cement.
- Yep.

And you wouldn't think. When
you break it apart right now,

- it's just sand.
- Yeah.

I bet there's a lot
of calcium carbonate in here.

Mm-hmm.

When you compare
this, elementally, to...

cement through the ages,

I think you're gonna get
a fairly accurate date.

Like from Roman cement
on forward.

Be interesting to see which
kind of cement this matches.

Oh, yeah.
That would be interesting.

- That would be crazy.
- Yep.

Because different
types of concrete mixtures

have been used throughout
the ages of human construction,

dating back as far
as ancient Egypt,

could determining
the contents of this material

help the team approximate
when this feature was created?

I believe the mortar
or the cement-like material

might reveal a-a when.

And maybe even tell us

where does it come from?
Is there a cultural association?

Hopefully,
there can be some answers

derived from this analysis.

That mixture
might be quite revealing.

It resembles, uh, on Lot 5,

- on the semicircular feature...
- Yeah.

- Yeah.
- ...it looks a lot like

the clay we found there.

What turned out to correlate
with the maroon till

- from the Money Pit. Yeah.
- Yeah. It'll be interesting

to see how it tests.

Yeah. Well, if it
corresponds to those two,

you've got something big
on your hands.

Yep.

Oh, look at that.

In addition
to the blue clay found on Lot 5

and, reportedly, by earlier
searchers in the Money Pit,

the Laginas and their team
have also discovered

a similar-looking
mortar-like material

in the round feature on Lot 5
that matched soil samples

from more than 100 feet deep
in the Money Pit area.

It's all smeared,
all through here.

So, if the team can
match this cement material

on Lot 8 to those structures,

could that mean all three
may have been built

by the same people?

To move
a 40,000-pound rock

into a position
on a nicely crafted rock cradle,

I mean, you have
to come up with a theory

as to why somebody was moved
to move that boulder.

And maybe they were trying to
hide something very important.

What in the heck went on
on this island?

Uh, it just raises
the mystery to new levels.

There was a reason for this,

and it wasn't just
to support that boulder.

- It could go deeper.
- It could. -[Laird] Yeah.

- And the archeology will tell.
- Okay.

Well, you know what?
I'm gonna let you two

get back to work.

All right. -[Rick] I have
a feeling those rocks are gonna

need a little bit of persuasion
to come out of there.

Yeah. I'll do my best.

- Okey doke.
- All right.

- Thank you.
- Good luck.

By digging
in the ground

and far back into history,

Rick, Marty, Craig,
and their team

are finding mounting evidence

that people journeyed
to Oak Island long ago

to hide precious--
and, perhaps, sacred-- secrets.

And through patience
and tireless effort,

they may have identified
not only structures

that those people inhabited,

but now, at least
two other locations

where those secrets
could lie buried.

So, as the team looks deeper,

have they uncovered
the final barriers

between them
and the ultimate answers?

Or will they encounter

something much harder
to break through

than bedrock and concrete?

Next time on
The Curse of Oak Island...

Heads up.

We've broken through
into the solution channel.

That's what we're looking for.

The three churches have exactly
the same stellar alignment

of Lot 5.

This could be
a tunnel shaft entrance.

Maybe it's just
right under here.

A piece of wood. -What's wood
doing down that deep?

Maybe this wood came from
the original Money Pit.

If there's wood
at the top,

maybe there's gold
at the bottom.

Possibly treasure on deck.

What have we got here?
