NARRATOR: Up on the
mountain, the team
has been attempting to drill
down to a depth of 40 feet
to verify the existence of a
potential void space behind,
what they believe, is a
backdoor entrance into a tunnel
that may run from
the backdoor site
directly to the Turtle Rock.
Earlier, we got
down to 35 feet,
and then we hit
something really hard.
So we're about 5 feet from where
the radar picked up an anomaly.
It's something
that we kind of would
expect from a possible tunnel.
OK.
All right.
That anomaly, we're hoping,
is the ceiling of a tunnel.
NARRATOR: To determine
if they've cleared
the hard layer of rock,
Peter checks the slurry
that comes out of the hole.
Look what I found.
A little piece of a seashell.
According to our
concrete expert,
Japanese, when they
ran out of sand,
they mixed some type of
coral in their cement.
This seashell could be
part of that process.
I mean, it's a wild
theory, but we're
not going to discount anything.
NARRATOR: Pieces of
seashell in the slurry
may be evidence of Japanese
concrete from a Golden
Lily treasure tunnel.
We're getting close.
I don't care how fast you go
as long as it keeps going down.
NARRATOR: Brad increases the
drill speed to its maximum
in order to bore through the
layer of hard volcanic rock.
[music playing]
NARRATOR: The water inside the
hole suddenly starts to drain.
NARRATOR: This is an indication
the drill may have punctured
the roof of a possible tunnel.
How deep are we?
Just past 40 feet.
Just past 40 feet.
So that's no coincidence.
There's something
going on at that level.
BRAD: The only way bubbles
could be coming out
of there is if there's a tunnel
down there where they're in it.
So what do we do next?
Next thing is that we're going
to drop a camera down there
and see what we got.
Sounds like a
great plan to me.
[laughter]
That's what we've
been waiting for.
That's what we're here for.
That's what we've
been waiting for.
All right.
It took us a while to get
here, but we're at that point
for taking pictures.
Let's get to it.
PETER: OK, guys.
NARRATOR: To verify
what's underground,
John brings the probe
camera to the drill site.
How's it looking, boys?
But did you lose water?
A lot of water.
A lot of water.
Let's get that
camera down there.
All right.
With the water disappearing
down this hole,
I'm pretty sure we're
on that void space.
I want to get a
camera down that hole
and see if we're on this void.
All right.
PETER: Let me do that.
JOHN: You're in the dry
section of the hole.
All right, you're coming down.
Nice and easy.
PETER: What's the measurement?
BRAD: 12 feet.
17 feet.
Go ahead.
In the hole.
Keep going.
You're smacking up
against the side.
Hold on.
BRAD: 20 feet.
JOHN: You're in the
side wall again.
Come back to center.
BRAD: 26 feet.
JOHN: Keep going.
BRAD: 33 feet.
You're good.
You're centered.
BRAD: 35.
Looks like we're going to
go swimming here shortly.
JOHN: Yep.
I see the water coming up.
Take the plunge.
BRAD: We're right at 40.
Hold it there.
Hold it there.
Don't go down any further,
because I can't see the side
wall or the pipe any longer.
Give me a slow twist in a 360.
I'm not seeing any side
walls whatsoever, Pete.
Let me take a look at that.
Just-- I have to see for myself.
This is really important.
Take my seat.
Now, twist slowly,
Brad, so you don't--
BRAD: How about
if I come up to--
--muck the water any more.
You just see water.
PETER: Oh, yeah.
I don't see anything.
JOHN: Well, I think it's a void.
It looks like you're
actually in a void space now.
