[narrator]
and anticipation has begun on Oak Island
for brothers Rick and Marty Lagina and their team.
I guess we're gonna get a look down the hole?
Yes, we are.
We'll see what the camera has to say.
[narrator]
underwater imaging expert Blaine Carr,
are about to begin a two-step operation
in the Money Pit area that they hope will reveal
the answers that could help solve
a 228-year-old treasure mystery.
So we're gonna enter the cave today at 140 to 142 feet.
Aladdin's Cave, as you deemed it last year.
So what do we hope to see once we get to the bottom?
Treasure chests, doubloons.
We want to know whether this cave is natural
or whether it's been influenced by people.
Secondarily to that, we'd like to see a way in and a way out.
The primary targets we were looking for were tunnels,
vaults, and of course, any high-density anomalies
that could reflect treasure.
[narrator]
representatives from Ideon Technologies
presented a stunning report
on data that had been collected deep underground
over the past two years
all across the Money Pit area.
Today, what we're gonna be discussing
are results from the Money Pit,
targets of interest.
[narrator]
had been placed at various depths
in previously drilled boreholes to scan for possible voids,
tunnels, and large objects.
Incredibly, a number of potential targets
were identified, suggesting that there could be
multiple treasure deposits buried in the Money Pit area.
Now, after drilling a new borehole
into Aladdin's Cave,
the team will first investigate it
using a high-definition camera
to look for more definitive evidence
that it may have been artificially created
and also what it might contain.
Okay, lights are on.
-You good? -You're good. Just go for it.
[narrator]
Blaine will then conduct a comprehensive sonar scan
to create a detailed map of the feature.
Okay, we can see the water.
[Rick]
Why not put eyes on that void
and see if we see anything, because
if we happen to see a feature down there
that we could orient off of with the camera,
it will be helpful to the 3D mapping sonar.
We should almost be to the water by the look of it.
Okay.
-Now you're right there. -Keep going.
[Rick]
will help us come to a greater understanding
of what this cave represents.
We're still seeing the side of the caisson.
This is going down.
Where are we at?
Okay, right there. Stop.
-We're right into it now. -Yup.
-There. -That's the edge of the caisson.
Okay, rotate around.
Yeah, those are the teeth right there.
You want him to lower it another foot?
Yeah, can you go down another six inches to a foot?
There we go. A little bit more.
And...
stop there.
So this would be the actual cavity here.
Gotta be a couple feet in by now.
Yeah, well, there's the wall.
-Isn't that the ledge? -Yeah.
It is a ledge.
[Marty]
we can start to see the walls, the sides of this cave.
So I would think there's something else there,
but that something else could be covered with silt.
It might not be obvious.
I want to get under that ledge.
Steve, can you really slowly lower it like three inches?
There you go.
[Rick] That looks like it's open, to me.
[Blaine] Yeah. Now you have a much bigger opening.
Good that it's open because that means
you can map it.
Yeah.
[Rick]
it's-it's quite interesting, very exciting.
We'd see some features.
It's certainly very plausible
that the camera is not seeing something
which may be on the floor of the cave.
Do you want to lower it down a little more
and see what you can see on the bottom?
We need to see exactly where the bottom is without any doubt.
Go.
I think we're facing down now.
So, Steve, just very slowly, another six inches or so.
-Six? -Yup.
That's good. A little bit more. Same again, please.
-There. What-- whoa, whoa, whoa. -Hold up.
Spin it around, 360.
-There. What's that? -What's that?
I can't tell if that's the bottom or...
-I'll wait for it to settle out. -There we go, there's something.
Visibility is actually better than we've seen.
What's this over here on the right?
There's something sticking out.
-Right there. -This piece right in here.
The way the shape is. It's kind of angular.
-That flat thing, you mean? -Yeah.
That's a piece of debris or something.
This is a very exciting thing,
and it's important to see whether it's manmade or not.
I think there's a chance the treasure might be placed there,
which would answer a lot of questions.
[narrator]
of possible manmade workings
some 150 feet underground
in a large cavern known as Aladdin's Cave...
We can tie a rope to it. Let's do that.
Start putting it down the hole that way.
Yeah.
[narrator]
in order to determine its exact dimensions
and to also see if there are tunnels
leading into the feature.
Okay, Scott. Good.
Okay, going in.
[narrator]
emits high-intensity radar pulses
that reflect off of objects and barriers,
such as the walls of a cavern,
in order to produce a three-dimensional map
of the underwater environment.
One hundred and forty feet down hole right now.
Going in and let's look at this.
[dramatic music playing]
[Blaine] Got it in a position where it's getting returns.
-Starting to spit out data. -I see it. Yup.
[man]
of the cavity.
How long will it be before we have
kind of a picture to look at?
I think what we'll do is we're gonna let it run,
and when we come back in the morning,
hopefully everything will be finished
and we're gonna see up into this cavity.
[Marty] All will be revealed.
I can wait till tomorrow to get good data.
Let's let it do its thing.
[narrator]
-Hey, Rick. -Hey, Rick.
-Hey, everybody.
what you've got to show us.
Okay, so the view that we're looking at here
is looking straight down.
-Okay. -So we're gonna try
to just slide it up into a 3D image.
-Oh. -You can see the yellow-green.
-Mm-hmm. -[Blaine] That's sloping down.
This darker red is the wall
in between us and the floor of the cavern.
That being said, we can't see the bottom.
Uh, the aspect of the sonar
looking out, the wall is blocking us
from seeing any further down.
-Mm-hmm. -What I can see,
see this blue line's crossing over
what look like two gaps?
-Yeah. -Mm-hmm.
[Blaine] Looks like an opening through here.
So I think you have the potential
for manmade ingress into a natural cavern.
Right.
What's the size of the cavity?
Without being able to see the bottom,
I just don't know the right answer,
'cause it's on a slope.
So, it varies.
It does slope off in one direction,
about 30 degrees.
But if anything was gonna be there, I mean,
gravity's gonna take everything to the bottom of that slope.
Right. Something could be buried in there.
-For sure. -Maybe the treasure.
I suppose it's quite possible.
[Rick]
that there might be a way into the cave.
It'd be even more interesting if we saw
some manmade feature in there.
Perhaps it's buried in the silts on the floor.
It's an interesting thing to investigate.
Something that makes you go, "Hmm, we need to see more."
Yeah.
There's some indication that the cave
has some things that aren't natural cave-like.
It could be some sort of treasure chamber.
That's why we're spending all this money and time
investigating it, and it checks a lot of the boxes.
Let's put it this way. We can't walk away from this
without knowing what it is.
It's unique.
So what I would do at this point
if we're really interested in seeing something else
is we would move over about...
-five, six feet. -Mm-hmm.
Put another hole down so the sonar can now see back
into this area and tell us,
are we indeed in an isolated cavern,
or is there an opening?
-Right. -And see if this carries on.
Yeah.
I would dearly love to put a hole there,
but I don't know.
Rick, what do you think? What do you wanna do?
I think you have to put another hole in
to get a different perspective.
-Yup. -But you can't walk away.
You have to... we have to exploit it as much as we can.
All right. I think we're all in agreement
as to that particular point.
Let's get some more data.
-Sounds good. -All right, back to it.
Let's go. We're gonna find that treasure.
I agree.
