Tonight on
The Curse of Oak Island...

-Come here, look at this.
-Oh, my gosh.

There's something here.

Could this be a continuation
of the stone path?

This is the Blair treasure map.

From what we can gather,

there were three
separate treasure caches.

- I say we get after it.
- Yeah.

Look at this.

So, this has got
to be the stone.

There's an "X" here.

Ringing loud and clear.

Oh-ho-ho-ho! Got it.

-Wow!
-Oh!

Come see this.

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.

-Hello, Vanessa.
-Hey, Vanessa.
Hi, Vanessa.

Hey, guys!
How are you doing today?

Excellent.

Thank you for joining us.

We know you're super busy.

I'll always take
your guys' call.

It's good to see all your faces.

Unlike most
new mornings on Oak Island,

which begin with brothers
Rick and Marty Lagina

and their team
searching for evidence

of a vast treasure deep
in the fabled Money Pit area...

It's been several years,
as you all know,

since we put canisters down.

and meeting via
video conference

with Vanessa Lucido,

the CEO of ROC Equipment.

You know, there's nothing like
that hammer grab coming out

and maybe carrying something
we really are looking for.

After weeks of drilling
in the Money Pit area,

they now believe
it is once again time

for a major dig operation
that could finally reveal

the answers
to a 230-year-old mystery.

Well, I got a question.
How deep are we going?

You know what, we have acquired

a couple of targets
that are deep.

So, you know, we want to talk
about being prepared for that,

being able to go down
approximately 220 feet.

Yeah, I can do that for sure.

identified a region
in the Money Pit area

where a large source of
gold and precious metals

lies buried somewhere below
a depth of 100 feet,

the Oak Island team has
recovered stunning evidence

of man-made workings
in several locations.

This sounds like
the Chappell Vault.

part of
the fabled Chappell Vault,

a massive wooden chest
first reported

by treasure hunters
Frederick Blair

and William Chappell
at a depth of 153 feet

back in 1897.

Now, in the coming weeks,

the Laginas and their team
intend to install

large-diameter steel caissons

in the hopes of
retrieving the vault

and any other
potential valuables

that may lie buried
more than 200 feet underground.

We want to find out from you,

are you available, say,

in a week or a couple weeks,
something like that?

My-my crews always enjoy
coming up there

and we do have equipment
available.

We'd love to make
this happen for you guys.

Well, that's a great answer.

We appreciate that, Vanessa.

Couldn't ask for
a better answer.

I am very happy
with the decision

of the group to dig.

And by that,
I mean put down these caissons

and see what's there.

It's easy to still have hope
that there's

treasure in the Money Pit.

The metals in the water has

kept my interest going.

It's kept my vigor
for this treasure hunt going.

It's time to dig.

So, the last time we were there,
we did ten-foot diameter shafts,

uh, we went rather large.

Are you still thinking that
large or what are we talking?

We want to do as many as we can.

It is kind of a rule of thumb

that a smaller diameter canister

will go down faster,
is that not correct?

You know,
we kind of have our sweet spot.

I'd say seven to eight feet,

we always are able
to move rather quickly.

Um, anything lower than that,
you're not getting as much out.

I don't think you guys would
be happy with that.

Anything bigger than that,
then we're looking at,

you know, increased trucking,

increased lead times,
that kind of stuff.

Well, actually, when we were

talking about it internally,
we actually were

modeling it at seven feet,
so that's perfect.

Okay.

You know,
we're certainly excited

and we're grateful that Vanessa
and her team are coming back.

I want to make
strident moves forward

towards understanding
the who, the what,

the when, the where,
the why, the how.

I want all of us
to be successful.

I want all of us to be excited

and I want all of us
to find the one thing.

Look, Vanessa,
from my standpoint,

I like everything I'm hearing.

As far as I'm concerned,
you can saddle up

the horses and start this way.

Okay. Well, let me
get with my team

and we'll see our availability

and how quickly
we can get there.

All right.

You better start making
some calls, Vanessa.

- We want to see you out here.
- All right, will do.

- Thank you.
- Thank you very much.
Appreciate it.

You're welcome. Thank you, guys.

So, Billy I think we still
have to metal detect here.

...Alex Lagina, along with metal
detection expert Katya Drayton

and Billy Gerhardt, are
continuing another important

investigation in the northern region

of the mysterious,
triangle-shaped swamp.

Once we detect this surface,

where do you think
you'll dump it?

Well, where we're sitting,

we know we have a strange
sort of rock thing over there.

So, we have to see that if

the path is anywhere,
it's through here, right?

Okay.

the Oak Island team has

uncovered a number of stunning,
man-made structures--

including a paved area

near the middle of the swamp,

as well as a stone road

in the southeast corner--

that they believed were used

by whomever may have buried
treasure in the Money Pit area.

However, in recent weeks,

they have also uncovered
a stone pathway

near what appears to be
a vault-like feature

composed of brick and slate

in the northern region.

So I think, Katya,
if you can just

metal detect this area here.

Then Billy, you'll scrape it
off, pile it there.

- Yeah.
- And then you can start
going over the spoils

- and then we'll work
our way back.
-Absolutely.

That's it.

Let's get to it.

have made the team suspect

that the Money Pit may not
be the only place

where treasure is buried
on Oak Island.

And if they can uncover
more of the pathway,

it may possibly lead
to other vault structures

that perhaps still contain
something of value.

Maybe this is
a little pathway to yet another

of those kind of shallow stone
and brick vaults in the swamp.

We should keep following it.

We need to learn
everything we can from it.

I think this is axe cut.

Came out of here.

Could've come from
the surface, hard to say.

It's pretty dark.

The stuff on the top
is a lighter color.

That looks like it's in
that little bit of a deeper...

Are you saying it probably
came from deep?

-Yeah.
-Yeah.

Let's add it to the bag.

Yeah, I'll set it aside.

Another really good indicator

that we're following
something man-made

is these axe chips
that we're finding, you know,

chips from axe-cut wood.

Uh, that is an indicator to me

that somebody was working
in the, in the near vicinity.

Was it somebody
searching for treasure,

or was it related
to a potential treasure deposit?

Hey, guys.

What are you seeing?

I'm not seeing enough
to make it obvious,

like a stack of rocks,
pile of rocks,

definitely put there by people.

Hmm.

We have one--
I can't tell the depth.

We have one looks like
axe-cut piece of wood.

I set that aside.

So, my hope here

is that we'll find an artifact

- or artifacts.
- Yeah.
-Mm-hmm.

Okay. Let's keep digging.

-Yep.
- See what we find.

Okay.

trying to solve this mystery,

and it continues to elude us

as it has the previous searchers

over the last 230 years.

The whole trend has been
higher elevation there

down to lower elevation here
for all the layers.

And that's why
you continue to work.

Wait. What's that?

There's something here.

Come here, look at this.

What in the heck is going on?

Oh, my gosh.

What in the heck is going on?

Oh, my gosh.

-A stake
right through the board.
-Oh, yeah.

While searching
for additional sections

of a cobblestone pathway

in the northern region
of the swamp...

It's just strange to have this

- right in the middle
of the board.
-Yeah.

of the Oak Island team
have just uncovered

another mysterious
man-made feature.

This is pounded through,
I think.

-Yeah.
-That's strange.

Yes, it is. Yeah.

The curious thing is,
that was interesting.

Fred found all these stakes

- in this area.
- Hmm.

It'll be very interesting to see

if these are the old ones
like the survey stakes

that Fred found
when he drained the swamp.

Right.

the late Oak Island landowner

and treasure hunter Fred Nolan,
drained the swamp,

and was astonished to discover

several uniform lines
of wooden stakes,

which were carbon-dated
to as early as the 16th century.

As a professional surveyor,
Fred believed that the stakes

had been used by someone
to create the swamp

in order to hide multiple
caches of treasure

and also speculated
that there could be

more valuables
hidden across the island.

There's another board there.

Wait. There's something here.

Hmm.

-What's that?
-What is that?

It's not a root.

Look at that.

There's a pole,

board under this board,

and maybe more boards
going that way.

Yeah.

Not sure what to make of this.

That's curious.

- Yeah.
-Anyway,

let's see if this is much bigger

than what we currently see.

- Yeah.
-Okay, Bill.

Uncover it slowly
and try to get a look

at what this represents.

Yep.

has just unearthed not only
another ancient survey marker

but perhaps a structure

that, like the nearby
vault-like feature,

was built to hide
something of value?

There's another board

underneath this round piece.

in the north end of
the bog are very, very curious.

These are
intentionally laid out.

There's another board there.

We have a multiplicity,
if you will,

of connect-the-dots
going on here.

How does it fit in
to the knowns?

What is its relationship
to the square slate structure

and this new stone path?

- Alex, why don't you text Laird.
- Okay.

See if he'd like to come out
and take a look-see.

There's one level. Two.

Maybe he can recommend
a way to take this apart.

Maybe it's level by level.

- There's three.
-I'll text him.

that they could have
found a structure

that may predate the discovery
of the Money Pit in 1795,

before the team
investigates any further

and risk damaging the feature,

he has decided to call in
archaeologist Laird Niven

to have it examined.

Hello. Oh.

-Yeah.
-Laird.

Well, the curious thing

which got our attention
is that board,

and that stake
driven through it.

-Coming up, yeah.
-Yeah.

And then there's
three layers of boards.

-Yeah.
-Why would these boards

be so degraded?

I guess it depends on species,

it depends on
the condition they were in

- when they were put there.
- Yep.

So, I think we get
Dr. Spooner in here,

- and he can take the samples.
- Right.

the team will have
geoscientist Dr. Ian Spooner

collect samples
for carbon testing

as soon as possible.

I would expose
as much as you can

for him to have a look.

- Yeah, let's finish up.
-Okay, Bill.

Always good to have an excuse
to dig a little more.

For sure.

of the northern region
of the swamp continues,

several hundred yards
to the west, on Lot 5...

-Hi.
-Hi.

How's it going?

It's going great.

archaeologists Fiona Steele
and Moya MacDonald

as they excavate

a large stone foundation
near the shoreline.

We've actually just opened up
this new test pit this morning.

Okay.

And that's the feature, also,

that had the clay
from the Money Pit?

That's exactly right.

the team has uncovered
not only man-made mortar

in the feature that
matches clay-like soils

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

but also multiple sections
that are believed

to have been built
at different periods

prior to the discovery
of the Money Pit.

Additionally,
they have uncovered

astonishing artifacts,
including 18th century pottery,

a 17th century coin
and Venetian trade beads,

and even a 14th century
lead barter token

that, just like the cross

that was uncovered
at Smith's Cove in 2017,

may be connected
to the medieval order

of the Knights Templar.

Is this the rock layer
that you need to get down to?

-Yeah. Mm-hmm.
- To find the artifacts.

the focus of attention
for multi-multi-generations.

Deposition of a treasure,
search for a treasure,

we have some data that
suggests that could be true.

We're exploring this area here,

where you can see there's a bit
of a space in between the rocks.

- Yes.
- We're trying to see
if that's an entranceway.

- Mm-hmm.
- It'd be great
if that's an entrance.

The hope is
that maybe we'll find

some sort of artifact here

that will tie us into
whatever is going on

- in that semicircular feature.
-Okay.

and his team of
archaeologists to help us

understand what Lot 5
represents,

but the process is slow,

and we just have to be patient.

If we can find
something that helps

tie the people that were here,

especially to the Money Pit,
that'd be huge.

- I think we are, bit by bit.
-Okay.

Well, can I, uh,
do some sifting?

- Oh, I'd love it. Good.
- Okay.

I don't think
I've seen a full war room

like this for a long time,

meaning it's gonna be
quite exciting.

an important meeting
with the team in the war room.

We have to follow
where the clues lead us,

and the clues
come from the research.

of the mysterious empty
vault-like structure

in the swamp,
Rick asked team members

Doug Crowell and Judi Rudebusch,

along with historian
Terry Deveau,

to search through
different archives

known to contain
previous searcher records

connected to
the Oak Island mystery.

Terry and Doug went down

to the Connecticut Museum
of Culture and History.

It was Rick's hope

that they might uncover clues
that could help

prove Fred Nolan's theory
regarding multiple treasures

being buried on Oak Island.

So, Doug,
I'll turn it over to you.

Well, this Oak Island material

that we found in Connecticut,

it really is due to
the work of Terry Deveau.

In amongst things that
he was researching down there,

he noted that this
particular individual,

who's face I think
you should be able to see

on the screen now:
William B. Goodwin.

So, William B. Goodwin

was born in 1866,
and he died in 1950.

He was from
a wealthy Hartford family

that was involved in
the insurance business.

But his work as a historian
really took off as well.

He also got involved
in archaeology, and Goodwin

had a habit of coming up
to Chester, Nova Scotia

every August on vacation.

Now, Chester is only a few
miles away from Oak Island.

So, with all
the drilling activity

and treasure hunting that
was going on on Oak Island,

that was a natural magnet
for William Goodwin

to go over and talk to people

and see if he could help
with the treasure hunt.

So, we know that he did

correspond with
many important figures

in Oak Island history.

Connecticut-based
businessman and historian

William B. Goodwin
began researching

the various treasure hunts
that had taken place

on Oak Island since the
Money Pit's discovery in 1795.

Throughout his life,
Goodwin amassed

a collection of documents
pertaining to the mystery,

especially records
connected to Frederick Blair,

the man who first
reported the existence

of the so-called Chappell Vault

153 feet deep in the Money Pit

back in 1897.

So, we found several letters

in 26 boxes
of Goodwin's collection

that had to do with Oak Island,

and Judi and I
have spent some time

trying to determine
what it all means,

and one of the things
here we found

in his notes on Oak Island is,

Goodwin calls it
the "Blair treasure map."

Oh, yeah.

Blair had in his possession
a treasure map.

Goodwin saw that map
during his time here,

and this is his diagram
and notations.

So this isn't
the original Blair map.

We don't know
where that might be

'cause nobody's
ever been aware of it.

So, there were three
original notations on the map,

three stones
that were indicated,

and from what we can gather

from William Goodwin's
notations, he was trying

from William Goodwin's
notations, he was trying

to figure out
if this map meant there were

three separate treasure caches
associated with

the west end of the island.

from William Goodwin's
notations,

he was trying to figure out

if this map meant there were
three separate treasure caches

associated with
the west end of the island.

In the war room,

historian Terry Deveau,
Doug Crowell

and Judi Rudebusch
have just presented

a map of the western end
of Oak Island

that they believe was
based on the records

of 19th century treasure
hunter Frederick Blair.

Was it discovered?
Is it still sitting out there?

We don't know at this point.

A map that suggests
there may be one,

or several buried
treasure caches

on the opposite end
of the island

from where
the Money Pit is located.

I've always thought
that Blair concentrated

in the Money Pit area,
but obviously, he was looking

at other places on the island.

There were three
original notations on the map,

three stones
that were indicated.

And one was at the corner
of Center Road

and the road past
the McGinnis house.

Another one was out
on the beach.

And another one
is further down Lot 1

near the McGinnis homestead.

Yes, exactly.

The McGinnises held onto
their land.

They didn't give it up.

And this Lot 1 stayed with
the one branch of the family

- all the way through.
- Yep.

Daniel McGinnis purchased Lot 21

and established a homestead
for his family

more than a mile
from the fabled treasure shaft.

He would spend
the rest of his life farming

while also remaining
actively involved

in Money Pit search operations.

Over the years,
many have wondered

why McGinnis chose
to build his home

on the opposite end
of Oak Island.

Could this map that
the team found

in the archives of William
Goodwin provide the answer?

And an even
more critical question

for Rick, Marty and the team

is do these possible treasure
caches remain hidden today?

Those three stones had
original notations on them.

The one at Center Road
had an "F, 11, E"

or-or an "F,
Roman numeral two, E" beside it.

The one on the beach had
an "F, 91" written beside it.

And the one further down
the Lot 1 property

had "F, 5" written by it,
along with this stone here.

That's drawn in by Goodwin.

He was exploring this map
personally here on the island.

If you look at the rocks
with the notations beside them.

If you can interpret "F, 91"
to be 91 feet from this rock,

is there a treasure

91 feet from the rock
on the beach?

Or were they notations
that lead to a central point?

So, he's using the boulders
just like Fred Nolan

to try to figure out
some treasure location.

Right.

This does sort of go
with Fred Nolan's idea

that there were multiple
caches across the island.

certainly suggests that Fred
may have been correct, i.e.

that there are possibly
multiple treasure depositions

across the width and breadth
of the island.

But it is not proof of that.

The proof is in the ground,
hopefully.

Gary, have you hammered
this area?

No, I haven't, Marty,
because it's so rough.

It's as rough as
a badger's butt out there.

I mean,
there's all hilly mounds...

- That rough.
- Yep.

I would say
the stone on the beach,

that seems to be
the place to start.

If we go looking
for these landmarks,

find the stones that are
the original landmarks

on the original map and try

to find out whether there's
any treasure caches nearby.

This is good work.
This is excellent work.

It may lead us to something.

Marty's right.

We follow the clues as we have
currently interpreted them.

So, I say we get after it.
Let's go look.

-All right.
-Let's see if
we can find the treasure.

You find anything yet?

Nope. What about you?

One shard.

continue excavating
the round feature on Lot 5...

...nearly a quarter mile
to the west on Lot 1...

Okay, folks, we're right at
the end of Center Road, so...

Okay.

Judi, you have the map with you.

to locate four boulders noted
on the so-called Goodwin map

to find out if they may
actually lead to one--

or more-- caches
of buried valuables.

There's two large
flat stones on the beach

shown on the treasure map.

One is to the south
of Center Road

and one is to the north
of Center Road.

We're going to try to find
the most recognizable

from the description given.

It has a large "X" in its center

and it has multiple squares
"in seams."

It sounds like
a framework of squares.

"X" marks the spot.

Yeah. Let's head down
to the beach.

- Yep.
- I can't wait.
Let's go find this.

It's a treasure map.

It has an "X" marks the spot.

I mean, it's classic.

- Let's look in this direction.
- We'll check out this way.

- Okay, mate.
- Okay.

We're looking for
a big flat stone.

It's supposed
to have a big "X" on it.

Something old.

A coin with an intriguing date.

Anything like that.

We're going to see
if there's anything

really actually special
about these boulders.

Well, there's a flat rock,
right there.

Oh, and it does
have a big "X" on it.

Oh, yeah.

Look.

Oh, it really does.

There's no mistaking that.

This is in the right spot.

just as the believed
treasure map indicated?

Hey, guys. Check this out.

may be on the verge
of a major discovery?

Look at that.

- A very prominent "X."
-Yeah.

All right, let's see
if there's anything around it

and see if there's any metals
under it as well.

Because if there
was something under it,

I'd detect it with this.

Right. Well, we'll stand back
and give you room.

No. Nothing underneath it
made of metal.

Nope. There's no metals
around it or underneath it.

Not that I can detect.

According to the notes,
this next stone

had an "X"
and the square shapes on it.

And I think we found it.

-Really?
-Yes.

Lead us to it.

Go check it out.

Okay, look it here, guys.

Seams and squares.

That does look like squares.

Isn't that something?

While following
an early 20th century map

depicting the western end
of Oak Island

and which is believed
to mark one or more

buried caches of treasure...

Take a look at the map,
you guys.

We are now right here
with the dot.

a potentially important clue.

Look at this.
The original description said

that it had an "X" on the stone
in the center of it.

There's a seam of an "X" here.

So, this has got
to be the stone.

Well, we ain't going anywhere
till we metal detect that.

We're looking for treasure,
that's a treasure map.

I'll go around it
and then on top of it.

These are real landmarks.

What does it all mean?

We have to work
to find that out.

I'm not getting
any hits unfortunately,

but just might be markers.

Sending us somewhere else
to find the treasure.

And that's the thing.

The map, the way
they were interpreting it,

off this rock is supposed
to be 91 feet back inland

parallel to Center Road.

So, we run a tape in that way,

there should be
a kidney-shaped rock.

So, if that kidney rock
is there, we're in business.

-Yeah.
-This is fantastic.

the next potential marker on
the mysterious treasure map...

You want to come check it out?

on Lot 5,
archaeologist Fiona Steele

and other members
of the team

are carefully excavating
a new section

of the mysterious round feature

that they believe may have once
been an entrance.

What are you finding?

I've got glass.
I've got some pearl ware.

And I just dug up what
looks like a rosehead nail.

And another piece of that
really shiny high-glaze brick.

What do you suppose the date on
that particular brick would be?

It's certainly not modern.
Bricks would've been in use,

you know,
anywhere from 1600s, onward.

-No!
-Awesome.

But I don't think
we really know at this point

until we get some comparisons
with some other known bricks

that were produced in known
areas at certain time frames.

So, once we finish
that analysis,

I think we'll have
a better idea.

The curiosity is

we've never seen a structure

made out of brick here
on the island,

yet we continue to find bricks
here, there and everywhere,

including the Lot 5 feature

and the so-called
vault in the swamp.

So, what does it mean?

Emma's compiling this database,

this timeline.

And hopefully it will tell us

what Lot 5 represents.

I await those answers.

It's also in this area,

right at the beginning
of what we think

could be a possible entranceway

into this portion
of the feature.

So, I think that's
pretty encouraging anyway.

Yeah, absolutely.

in the stone foundation
on Lot 5...

We're aiming to try and keep
the same bearing as the road.

And what shape is the stone?

It's kidney-shaped.

Doug, Gary, and other
members of the team

are using a tape measure
to look for another marker

noted on the so-called
Goodwin treasure map.

A kidney-shaped stone that,
according to the map,

is located 91 feet
from the boulder

marked with an "X" and square,

which the team already located
near the beach.

Doug, hold up.

That's it. 91 feet.

So, at 91 feet
there's one stone here.

Look how it comes in like
that way, like a kidney bean.

Yeah, this is more
kidney bean shaped.

If you're using natural stones
as markers,

then that's the most
fitting description

of the shape of this stone.

Well, bloody hell, mate,
we're three for three now.

What's got me excited
is the landmarks

- seem to be proving true.
- Yeah.

that's on the map,

it shows the map
is completely valid for me.

Time for some metal detecting.

I can't wait to see
where this leads us.

There we go.

are important, and maybe

the positions of the rocks
will help solve the mystery.

I haven't got any metal hits

around the rock
or on top of the rock.

But you've seen the area.

Billy's guys have got to do some
serious clearing in this area.

Well, we've got one more
major landmark to find.

What's the description
of that boulder, Judi?

It has a top cleaved off
like lightning hit it.

Let's go to that fourth one,
and hopefully, hit the jackpot.

Let's see if we can find it.

So we're gonna try and find
the other landmark on the map.

The next stone
on the Blair treasure map

had a notation beside it.

It said, "F-5,"
suggesting perhaps

that something was buried
five feet away.

I mean, Frederick Blair
spent his whole life

chasing the treasure.

That means,
if we can find the next stone,

this gives legitimacy
to the map.

We're hoping
that there might be something

buried very near the stone.

- Oh!
- Oh! That's what
we're talking about!

Yeah. No mistaking this one.

-Looks like it was
cleaved in half by lightning.
- Yup.

I can see both sides
right there,

- and it looks like
it was blasted apart.
- Mm.

Oh, yeah, look at that.

So, his notes show
the big boulder

with a hole in the top of it.

- This is on the proper side...
- Uh-huh.

...according to his diagram.

Wait. Are you telling me
that this is the last spot

that we really need
to find, because

a treasure is within, like, five
feet of where these rocks are?

If that's what
the notation means, then,

the treasure could be within
five feet of this boulder.

It's go time, Doug!

We're going to clear
all this area out,

and hopefully,
find some treasure.

- Fingers crossed.
-Yeah.

- I'm gonna step back
out of the way.
- Okay.

Goodwin did not have
a metal detector or a Drayton.

Signal right at the base of it.

That's exciting.

Let's dig this up, Jack.
Let's see if we can get to it.

and potentially historic moment
for members

of Rick and Marty Lagina's team.

I've been waiting for years
to see your gold dance.

Gary Drayton has detected
a buried

metal object right next
to a mysterious boulder

that was marked
on a believed treasure map.

Let's see.

Ringing loud and clear.
Let me pinpoint it.

- Oh!
- Oh, it's singing loud
and clear.

Oh.

Rapid vibration.

- Wow, that's big!
- Oh, look at that pin.

Yeah, that's not rebar.

This is an old,
hand-forged piece of iron.

If I was putting a date on this,

I'd say you're in the 1700s
or a lot older.

Really? Wow.

And that came from

right underneath the boulder?

- Yeah.
-It sure

looks like some kind
of cribbing spike

that you would use
for tunneling.

- Okay.
-Weren't the swages

- found nearby?
- Yeah, mate.

A stone's throw away over there.

Though maybe
someone was tunneling?

Who knows?

Feel how heavy that is, Rick.

Wow! Wow!

while investigating nearby
on Lot 21,

Gary, Rick and Dan Henskee

unearthed two iron tools

designed for digging
through rock, known as "swages."

For tunneling?

Carmen Legge examined them...

as much as six centuries.

Who would've thought
that we'd find something

possibly very important
to the treasure hunt in general

- on the opposite side of
the island from the Money Pit?
- Yeah.

that the team has just found
another critical clue

to help prove the authenticity
of this treasure map?

If so, could that mean

that something of great value
is actually buried in this area?

You know what it does for me?

It takes this
from a rock on a map

to a place where there's been
human intervention.

Someone's been looking here
or depositing something.

- Yeah.
-I think
what we've got to do is go back

and inform the guys of what
we found in regards to this map.

It is a top-pocket find
as far as I'm concerned,

but unless you guys
are paying me laundry bill,

it's going in the bag.

Fantastic day.

-Hey.
-Hey, Alex.

So, we're trying
to keep it drained.

It's not as nice
as it was earlier.

So, those are the boards.

- There's the stake
driven down through it.
-Right.

...Rick Lagina
and members of the team

meet with geoscientist
Dr. Ian Spooner

and surveyor Steve Guptill

in the northern region
of the swamp.

That board ends there,

but there's at least
one more board underneath,

- and that continues
to go that way.
- Right.

the recently unearthed
wooden platform

and believed survey stakes
that are connected to it.

- There's layers to it.
-There's layers?

- Kind of like steps going down.
-Mm-hmm. Okay.

- What do you make of that, Ian?
- It's hard to say.

I think
that stake is reminiscent

of everything I saw along the
stone path by the stone road.

- So that gets me
sort of interested.
- Right.

Look at that.

after uncovering
a massive stone road

in the southeast corner
of the swamp...

This is really cool.

in order to unload some kind
of heavy cargo

from a ship onto Oak Island...

That's cut.

part of a cobblestone path
heading to the north.

It was bordered by a number
of similar survey stakes.

Survey stakes
which Dr. Spooner carbon-dated

to as early as the 17th century.

Some kind of planking.

that the team has now found
a wooden structure

in the northern region
of the swamp

that is connected to the pathway
and the stone road?

If so, what is its purpose?

And could it also be related
to heavy cargo

that may have been left on Oak
Island as much as 400 years ago?

From a science perspective,
if we get some stuff

underneath it, that's something
we can put a date on.

- Yeah.
-Could it be

where the cobble path ends
and meets land,

and they just wanted
a transition

from the cobble path
to dry land?

And the elevation
matches the cobble path.

The elevation matches
the cobble path.

So, I really think
the cobble path

comes to here.
It's the end of the cobble path

and transition to dry land.

And somebody threw
some wood down

as a barrier between
the cobble path and the uplands.

-Maybe.
- Yeah.

of the Oak Island swamp,

surveyor Steve Guptill

has just informed Rick Lagina

and other members of the team

that the newly unearthed
wooden platform

may be an extension
of the nearby cobblestone path.

Let's get those boards
out of there.

to lead
to another hidden feature?

Or perhaps to cover something
of great value?

Underneath it, it is wet.

So maybe somebody just put some
planks down to walk out on.

- Yeah.
-These boards
are so degraded.

-Yeah.
-It's sort of hard
to date the boards.

But you could date that stake.

What I'd do is, we cut
the ends off if we could,

and I'd date
from right in the center.

- Yeah.
- And we'll see what we're...

- what we're working with.
-Okay.

There's two more boards.

The stakes-- I'll be honest,
they're very confusing.

But they are purposeful.

There is intelligent design
to them.

There is a reason why
those stakes are there.

That's beautiful.

Why would somebody go to the
lengths to build a platform

in a corner of a bog, in close
proximity to this cobble path?

What is the relationship?

Were they built
at the same time?

And always, always why?

- This is the one we found
at the surface.
-Yup.

Similar,
but not as well preserved,

which can be explained by the
fact that it was at the surface.

Somebody knew
what they were doing.

It's just one long cut.

So now we have two things

that are similar in design

- that we can send
for carbon-dating.
- Yeah.

- I would take both.
-Right.

Everything about
this feature is puzzling,

but maybe
it's more than one puzzle.

Maybe it's two or three puzzles.

There are
so many questions here.

So, we have to do some homework
here and we have to really think

about what this means.

So, I'll take these back.

And I'll let you know as soon

- as I cut these, what we've got.
- Okay.

Let's get some rain gear on
and keep digging.

Okey-doke.

for the most extensive dig

ever attempted
in the Money Pit area,

Rick, Marty, Craig and
their team have now also found

a mysterious map,

as well as a literal pathway

that may lead
to even more hidden secrets

all across Oak Island.

And while it will take tireless
efforts to pursue the answers,

the possible rewards
that await them may be greater

than they ever imagined.

Next time on
The Curse of Oak Island...

of a big effort
by the entire team.

- It's time to dig.
- It is.

Guys. You're not going
to believe this.

- Wow!
- Is that a diamond?!

So somebody of importance
and wealth was on Lot 5.

- I think so.
- That's pretty significant.

We hit a lot of wood.

- It's a structure.
-Wow!
This is a good chance

of being the original
Money Pit location.

Absolutely.
