01x06 - A Hidden Chamber

[bunniefuu]

We think there's a grave.

We're gonna first figure out
if it is a crime scene.

Obviously, if it is,
the whole world's gonna change.

- Is that a bone?
- Yeah.

Gabriel: I'm bringing in
all the equipment,

because we found some
really hard evidence

that the Spanish were here.

A little tricky to get
this thing up in this pit.

[ bleep ]

Dan: Today we're bringing
in a geophysicist.

So what we found is an area that
could potentially be a chamber.

This is big.

This looks like it right here.

Hey, Dad, you want to come
check this out?

Narrator: 500 years ago,
the Aztecs possessed

one of the greatest treasures
the world has ever seen.

Word of this treasure attracted
the attention

of the Spanish conquistadors,

but when they came for the gold,

it was already gone,

hidden by Emperor Montezuma

in locations throughout what is
now the American Southwest.

Now,
three treasure hunting teams,

all with different approaches,

are closing in
on what they believe

is the location
of the lost Aztec gold.

This right here, this is
definitely manmade activity.

The Dillmans are following
a trail

blazed by the research
of their grandfather.

I believe it's my destiny
to find it for the family.

The Villescas
are treasure seekers

descended from
Spanish conquistadors.

They believe the Spanish found
the gold...

All right. Here we go.

And melted it into bars

hidden throughout
the American Southwest.

Gabriel: If anybody's gonna
find it, it's gonna be us.

And finally, Hoagland and Hegg.

Fire in the hole!

They believe the treasure
is hidden inside mines

along well known
Aztec trade routes.

If anything happens,
be ready to go.

Decades of searching.

That's old as hell.

Three different theories.

Kevin: That's what I do.
I go find stuff.

Which one of these teams
will be proven right...

and be the first to find

the lost gold of the Aztecs?

Gabriel: Clues and evidence
has lead us here.

Let's get after it.

Gabriel Villescas
and his father Ramon

are headed back
to the Fire Pits,

this time with extra manpower
and equipment.

A discovery made at this site

suggests the Spanish could have
melted gold here.

Gabriel: You know, this is
a really big day for us.

You know, finding that crucible
here on this spot

gave me the confidence
to pull the trigger

and bring in all this equipment.

This is a long time
in the making.

We've spent years searching
for this place.

You know, we have a lot
of money invested in this.

We're all in. We're just gonna
go on ahead and keep on digging

till the last drop of diesel
is burnt.

Come on in, everybody.
Let's gather around.

All right, well, first of all,
I'd like to thank all you guys

for making it.

As you guys know, me and my dad
have been searching

for Spanish treasure
for quite some time,

and all the clues
have lead us right here.

We found evidence
of Spanish occupation here,

and we think somebody found
a bar of gold here a while back.

The Spanish wouldn't have went
through all this trouble

just to bury one bar.

So all we have to do
is dig and search for it,

and that's why you guys
are here.

You three gentlemen
will go with Jerome

to Fire Pit number one,
which is directly behind us.

Robert, you will go
to Fire Pit number two,

which is gonna be on
the south side.

And you two gentlemen will be
going to Fire Pit number three,

which is on the north side.

All right, you guys,
you all know

where you're supposed to be.

Let's have a good safe day.

Let's get out there
and find some gold.

- Whoo!
- Let's go.

Narrator:
Gabe is working all three pits

using different methods

to maximize his chances
of finding gold.

Jerome will use the excavator

to break through the dense
layer of rock.

Another two-man crew will be
working with metal detectors...

[ beeping ]

while Gabe and his father
resume sifting material

with the shaker box.

Gabriel: I think let's put this
right over here.

This looks like as good a spot
as any. What do you think?

Ramon: All right.
I'll get down and guide you.

Our ultimate goal here
on this side

is to locate a mass amount
of gold buried somewhere

- within this soil.
- Ramon: You need to drop it

- a little bit more.
- Good? Okay.

Ramon: That'll work.

We got everything
invested in this.

I just hope that we're sitting
on top of something very huge.

I just got to get this machine
in the pit and get to digging.

A little tricky to get
this thing up in this pit.

[ bleep ]

Jerome: So what I'm doing
is stretching the boom out

and placing the bucket
on the ground

so I can get this machine
stabilized.

Just got to get it to stop
rocking and gather myself,

'cause this is a little bit
scary right now.

Oh, yeah.
Got her in there.

Time to get to work now.

- What've you got on your left?
- Oh, not...

- No. No, no, no, no, no.
- Chris: Not a lot?

Kevin: Hard right. Hard right.
Hard right. Hard right.

Yeah, we got ugly rock.

Narrator: Miners
Kevin Hoagland and Chris Hegg

are headed back
to an ancient mine

along an Aztec trading route.

Recently, they discovered
what may be a gravesite

- near the mine.
- Oh.

I mean, it's the most
disrespectful way

you could do this.

Their search for the treasure
is temporarily on hold

pending an investigation

by the Mineral County
sheriff's department.

Kevin:
We're on Rattle Snake Mountain

just above the gravesite,

waiting on the sheriff's
department to get here.

When they show up,
they're going to treat it

as a crime scene no matter what

until they can prove it
otherwise.

So that puts us in a spot
of absolute limbo.

We don't know
what's in that gravesite.

It's going to be up to them

on whether we go back to work
immediately or not.

- Good morning, gentlemen.
- Both: Morning.

Undersheriff Ferguson,

- this is Kevin.
- Nice to meet you.

Thank you, gentlemen,
for coming up.

- Not a problem.
- Right down below us

is where we think
there's a grave.

What's your standard
procedure for this?

We're gonna first figure out
if it is a crime scene.

Obviously, if it is, the whole
world is going to change.

We're gonna have to contact

Nevada Division
of Investigations.

They'll exhume the body
and any evidence around.

We have a lot
of Native American burials

and different things found
in this area.

So once we send it off
to a lab to be tested,

if it comes back
that it's Native American,

then we need to exhume
the rest of the bones up,

and then send them over
to the tribe,

and then they'll do
a burial of it.

Normally when we find old bones,
they carbon-date them.

The last ones we found
dated back to 1710,

plus or minus 20 years.

What we're interested
in finding right now

is just the skull
and probably the lower jaw.

That way they can do
the testing on the teeth,

- the dentures.
- Sure.

The general rule when you think
you've encountered a grave...

Well, here it is, guys.

Just treat it like
it's the worst case scenario,

like this could be maybe
a m*rder scene or something

that's been recent.

What do you think?
Just right here below it?

So the downside of this,
calling the sheriff,

is we could be shut down.

We could be shut down for
a while, and that concerns us.

What are you guys seeing?
Anything?

Nothing right now.
Just a bunch of rocks.

Bigger rocks we're trying
to get pulled out of the way.

Kevin: If it is a body,
it's sad to think

that there's somebody
out in the middle of nowhere

that may have never got a chance
to say their goodbyes.

It's somebody, and that somebody
had somebody else somewhere.

- Is that a bone?
- Yeah.

So what are you guys seeing?
Anything?

Nothing right now.
Just a bunch of rocks.

Bigger rocks we're trying
to get pulled out of the way.

Narrator:
While investigating

a possible burial site
near the mine,

the Mineral County
sheriff's department...

- Is that a bone?
- Yeah.

Makes a disturbing find.

You want to take
a photo real quick, L.T.?

- Here.
- Yeah, put 'em in the basket.

How about... real quick,

how about we start digging
down deeper, Johnny?

We'll get that sifter in case
we got any more bones.

- How many bones have you found?
- All: Three.

- So far.
- What are you guys thinking?

Just from the size of
the bones I'm seeing now,

they kind of indicate
they might be animal.

Definitely looks like
a pelvis from an animal.

It's probably from a dog,
a smaller animal like that.

- Yeah.
- Whew.

All right. I can relax now.

- You all right?
- Mm-hmm.

I'm relieved that
this is just a canine.

You know, I can take a breath.

It's definitely
not human remains.

I really thank you guys
for coming out.

Good thing is
it's not gonna stop you.

- That's good.
- Yeah, so you're officially

releasing this site
back to us right now.

- It's 100% yours.
- Thank you.

- Thank you.
- Thank you very much.

The entire team from
the sheriff's department

was absolutely phenomenal.

They came in.
They took charge.

They treated it like
a true investigation,

which it should've been,

and it deserved
that type of respect.

Well, that was a relief,
honestly.

That was. It is.
That is a relief.

All right.

I'm eager to get back in the
mine, so let's get back to work.

Yeah, we need to.

Narrator: The Dillman team are
continuing their exploration

of the north side of the canyon,

looking for a tunnel system.

After discovering
a water glyph...

You got to be kidding me.

Similar to the one
his grandfather found in 1982,

Dan sent a rock climber
down to investigate.

But the footage didn't reveal
any hard evidence

of a tunnel or chamber entrance.

Let's get out of there, man.

- Good morning, Ryan.
- Morning.

So the Dillmans have hired
geophysicist Ryan North

to take their search deeper.

Let's go check it out.

Dan:
Using the ERT technology

enables us
to really cover more ground.

All right,
just right over here, guys.

Excellent.

It allows us to scan the canyon

looking for tunnel systems,
caverns, cavities,

things that you can't just
normally do

by walking around looking.

All right, so this is the north
end of Cave Lakes Canyon.

What I'm hoping for us to try
to prove today, that in fact

there are possibly
tunnel systems, caverns,

something that ties the south
side to the north side.

We're gonna be using electrical
resistivity tomography.

So essentially, we lay out
a long line of metal stakes

that are put into the ground
at an even spacing.

We'll put a current
into the ground.

And we're looking for areas

that are very resistive,
which are voids,

tunnels, caverns,
anything like that.

Narrator: Electrical
resistivity tomography, or ERT,

is the process of directing
an electrical current

into the ground.

The electricity can only travel
through solid objects,

so any open spaces will show up
on the scans as voids.

Dan hopes that the chamber
and tunnels

mentioned in
his grandfather's tapes...

will show up on these ERT scans,

and perhaps even show the way
to get into them.

All right, guys.
I'm gonna set all the stuff out

that we're gonna need
to take down.

Do it.

Four spools of electrode cable.

Derrick: For me,
I definitely feel

like I'm earning my place
on the team.

My dad gets the opportunity
to continue what he's doing,

which is out there researching,
which I don't mind.

I really do feel
like I'm earning my keep.

Ryan:
Just set everything right here.

Let's go grab a stake

and start laying out
the west end of the line.

Next step is we need to go

and put an electrode
every four meters,

connect all the electrodes
and the take-outs

to the one next to them.

And not only just him,

but those who came
before him and me...

My uncle Johnny, my uncle Paul,
my great-grandpa.

And if it means me hiking
all throughout this canyon

and driving stakes in the
ground, then I'm all for it.

All right, so we're gonna
the contact resistance tests.

So we need to see if we can get
some data collected.

- Let's fire it up.
- [ whirring, sputtering ]

All right, so there's fairly
high resistance.

If there's any kind of tunnel
or a chamber under here,

the resistivity tomography
survey can find it.

Narrator: As the Dillman team
waits for their ERT results,

the Villescas team continues
their work at the Fire Pits.

Get a little bit more.

Gabriel: We got guys spread out
all over this place.

I got Jerome
in Fire Pit number one,

and he's digging
with the excavator.

All right, guys, I'm gonna start
digging right here,

and I'm gonna
put it over there, okay?

In Fire Put number three,
I got two other guys

scanning with metal detectors.

- [ beeping ]
- Pretty strong signal here.

My dad and I are processing
Fire Pit number two.

We believe this is the spot.

We're gonna dig until
the money runs out.

All right.
Let's see what we got here.

I'm not seeing nothing
too good yet.

I like that it's dry.
It's sifting really easy.

- Ramon: Yeah.
- Look at all these white rocks.

- Look at that. Yeah.
- That looks like pottery.

Gabriel: Almost like
a piece of pottery.

We got to look at everything.

- Oh. Look at this.
- What is that?

Can you clean that up?

Gabriel:
Yeah. Yeah, that's...

- That's a piece of iron.
- Let me see it.

Couldn't be a nail.

- Has to be some kind of tool...
- Spike?

- Or spike or...
- Well, it's pointy.

Ramon: It's got a slit
on the back.

Gabriel:
Well, it's not a nail, then.

This large piece of wrought-iron
that we just found,

to me it looks
like it's hand-forged,

because it's got a crack
and it's starting

to split open on the side.

- It's got some kind of...
- Ramon: Design, huh?

A fancy little design.
Look at that.

The metal's, like,
shaped square.

Ramon:
What about the back of it?

I mean, it's some type of a,

- like...
- Like a spear?

- Yeah, like a spear, exactly.
- Huh.

It would've had
a long pole, huh?

Yeah, you know
what this looks like?

- Kind of looks like a pike.
- Huh.

If I didn't know any better,

I would say that's exactly
what that is.

Narrator: Spanish conquistadors
attached pikes at the end

of long wooden shafts
for use in battle.

They were sometimes used
to hold off attackers

while shooters prepared
their weapons.

This technique made the pike
a devastating weapon

in the conquest of the Aztec.

- It was made to k*ll.
- Oh, that's a weapon for sure.

I mean, it's not super sharp,

but, I mean, it could've been
damaged, you know?

It's been buried for many moons.

Gabriel: We're gonna continue
looking in this area.

You know, we might find
something else.

All right.

- So I got the GPR.
- Yup.

You'll radar the tunnel?

Narrator: With the sheriff's
department clearing the way

for work to continue
on the mine,

Kevin and Chris are preparing
to explore the pit

that may have been created

by local treasure hunter
Roy Ladd.

I'll grab the radar.

They're bringing in
ground-penetrating radar

to try to find out what
Roy may have been looking for.

Chris: If Roy was up here,
we'd both agree,

that pit is the key.
He was there for a reason.

- Come on, baby.
- All right.

He was onto something, and I
think he was really close to it.

That's a little slippery.

Well, we're gonna use what Roy
couldn't use back in the day,

ground-penetrating radar.

So we can actually push
a signal into the ground,

and if there's anything
in there,

we're gonna be able to see it,
like Superman vision.

We're gonna actually look
into the rock.

Got it.

We might actually find
something down there.

Kevin: With all of the headframe
and all of the wood going down,

I really believe that there's
a lot more information there

than what we've even seen.

But it could be nothing more
than just a pit.

Chris:
All right, I'm ready.

Getting down there
and running the GPR,

it's just another thing
that you check off,

because if we walked away
from it right now

neither one of us would feel
good about it.

Hey. Easy, slow.

Listen and look at everything
on your way down.

If anything gets sketchy,
if anything gets weird,

if I don't like it,
I'm pulling you out.

Chris: All right.

I know you want
to get down there,

and I know you want to see
what's going on,

but it ain't worth it.

All right, on rope.

Okay, slack.

Oh! That was fast.

- Are you all right?
- Chris: Yup. I'm good.

- Okay.
- Little slack. Yup.

You're on rope.

Chris: More slack.

- Everything all right?
- We're almost at the bottom.

Okay, I got my feet on
the bottom. You can slack me.

Kevin: Before you go off line,
give me some air readings.

- I'm still at 20.9.
- Copy that.

- I want to fire up this GPR.
- Kevin: Copy that.

[ beeps ]

Okay, Kevin,
I got this thing fired up.

Ready to go.

You're on it.

Back there.

Narrator: By moving the GPR unit
along the edge of the pit,

Chris will be able to detect
if there are any gaps

or openings behind the walls.

Oh, [ bleep ].

[ beeps ]

All right, Kevin.
I'm about ready. How about you?

I'm good. Let me know,
and I'll pull up slack.

Man, this place
is really sketchy.

Okay.

- Whew. This thing's a bear.
- Yeah, I can imagine.

Good to have you back, brother.

Good to be back.

Hopefully, we can see something
off the footage

and get a better idea.

Chris:
If there's anything in there,

especially
a cavity or something,

it's going to reflect that
back to the machine,

and we think there's more
to this story.

Kevin:
Let's get out of here.

So we went out and surveyed

several approximately


of the north side of the canyon.

In one of them, I think
we saw something interesting.

So let me pull that up.

Narrator: The Dillmans
are getting the results

of the ERT scan from around
the area of the water glyph.

So what we have here
in this one section,

this is the distance
along the line.

This is our depth.
Down here is our resistivity.

What we see is it's really high
across the whole site.

But right here is an area
of interest.

Fairy large target
in the center here,

and a few smaller ones
off to the east there.

It's fairly interesting
based on what you've told me

you're looking for
in the area we're looking.

Are you able to see how big
it is from here roughly?

We can make approximates.

It looks like it's somewhere
around 30 meters,

about 100 feet deep.

And it could be somewhere
on the order

of 30 to 40 feet in diameter.

- That's amazing.
- Derrick: I mean,

just looking at that...
That just...

It screams to me
cavern or chamber.

Dan: That may be the chamber
that we're looking for,

and these other anomalies may be
the tunneling to get there.

And we just won't know until
we're boots on the ground

and we start putting some
shovels in the earth.

Dan: Hearing Ryan say that
we've got a massive chamber,

to me is ground-breaking
in our research.

Because my grandfather told us
to specifically

find this chamber.

And now we believe we got it.

So if this is the chamber,

what could these two voids be?

I mean, yeah, 'cause to me
looking at this,

they're lined up.

It looks like it's almost
in a straight line

leading straight to the cavern,

so that could potentially
be a tunnel system.

- It could be the entrance.
- Yeah.

So how far from the top
do you think it would be

if we were to try to drill down?

It's gonna be at least
somewhere around 30 meters,

around 100 feet,
and it's almost inaccessible

for drilling in that area.

But I think we're fairly close
to the cliff face,

so it might be a shorter path
to go in from the vertical wall.

Dan: The next step is getting
into this chamber.

We've got to move
a lot of earth and rock,

but we've got to get in there.

This right here,
this may be everything

that we've been looking for
at this location.

More?

Get a little bit more.

Narrator: The Villescas team
are continuing

their accelerated search
of the Fire Pits.

While Jerome is working the
excavator in Fire Pit one...

Hey, guys! I need you guys.
Look at this stuff right here.

And I'll be... I'll spin back
around in a few minutes.

And workers metal detect
Fire Pit three...

He's getting a pretty
strong signal here.

Gabriel and his father
are searching Fire Pit two

in hopes of finding
Spanish gold bars.

So, Dad, I'm gonna grab
this pile and start building,

like, a little wall
so I can back-drag it.

I'll guide you.

Gabriel: My Dad and I
are in Fire Pit number two,

and we're gonna run dirt
from all different areas,

all different sides of the pit.

So what I'm doing is
I'm taking the loader

and I'm back-dragging
the material

about six to eight inches deep.

That way we can run
the metal detectors

and make sure we don't miss
a single thing.

[ beeping ]

I'm looking for those nice
solid, solid tones.

[ buzzing, beeping ]

I got a little hit.

- [ beeping intensifies ]
- Something there, huh?

Shovel through there.

- [ beeping ]
- Wait.

There's something here.

[ beeping ]

Oh, yeah. Look at that.

It's, uh...

Well, I don't know what it is.

[ beeping ]

I don't know, but it's got
a nice... a nice rounded edge.

Copper or bronze.

I mean, look at
the patina on it. It's...

Take that off very carefully.
I don't want to destroy it.

Ramon: Like a pin, huh?
Look at that.

Gabriel: Oh.
I think you might be right.

It might be a pin of some sort.

Maybe like a pin, like it goes,

like, right in there
kind of thing?

- Ramon: Mm-hmm.
- Or a badge?

- Ramon: It could be a badge.
- Maybe a badge.

- Who'd wear a badge like that?
- Maybe a lesser officer.

I don't know if it's Spanish.
I don't know what it is.

I have no idea,
but definitely not gold.

Nope.

Gabriel: You know, this
is a really interesting find.

You know, I don't know exactly
what it is.

It's definitely a piece
of something larger.

It's probably brass or copper
because it's tarnished green,

and that's indicative
of that type of material

as it gets old and aged.

But it's fascinating
and it's a great find.

Same area, but we missed this
in the table.

I think we should double check
this again.

I mean, if we missed this,

- we need to keep on going.
- Scan it again?

Gabriel:
Let's keep on going on it.

Man, I can't wait to look
at this data.

You want to tell me
what you're all excited about?

Wait and see.

Narrator: Kevin and Chris have
just completed a GPR scan

of the section of the mine
known as the Pit.

I think I've seen something.

Dude, you're awfully excited.
I mean, you're moving.

Yeah.

They're hoping
this will shed some light

on what local
treasure hunter Roy Ladd

might've been looking for
so deep into the mountain.

Okay. Look at that.

There's the face
we were against.

- Holy...
- Two feet in.

Remember, we're looking from
this side from the top down.

So we're looking into
the cavity on the bottom.

We're looking two feet in.
There's a cavity in there.

I don't know
if it's natural or manmade,

but it's big enough.

I think we can get in there.

There's a cavity back there.
Two feet.

Roy was two feet from it.

That's spooky.

Either Roy knew it was there
or he had no idea.

If it's a no, then he may be
just be lucking into it.

You know what?
I think Roy had a hunch

and he worked on that pit
till the day he died.

I think he just ran out of time.

We got to go through that wall.

That can sit there for
the rest of our lives

if it means bringing
that roof down.

That's not gonna happen.

Kevin:
Finding it is one thing.

Getting to it is gonna be
a whole other challenge.

And this is a shaky area.

We're gonna have to sit down
and really give a lot of thought

on how we're going
to get from here

through that two feet of wall.

We've got to figure out
a way to do it safely,

to where neither one of us
end up dead.

[ Chris mutters ]

I don't want to collapse it
down on top of us.

I don't want to collapse it down
to where we lose it.

We've got to really think
this one through.

This is going to be
the biggest challenge

that we've had to date.

'Cause now we got to bring down

an underground wall
in a bad spot.

Narrator: The Dillman team
is headed to an area

where their ERT scan
indicated the location

of a possible chamber.

With the chamber being at least


Dan is trying to see
if there is an entrance

through the canyon wall.

Dan:
Derrick, you got that GPS?

Derrick: Yup, I got it here.
Hold on.

What this is saying,
we probably got about,

say, 40 yards up ahead.

The discovery of this chamber
from this ERT data

has got my excited.

- Hold on, guys.
- Because my grandfather

constantly spoke about
a chamber that held treasure.

This looks so cool.

Could this be the chamber

that he was speaking about?

All right, guys,
so based on this GPS here,

we're standing right in front
of where this cavern is

based on the ERT readings.

Right,
that's what Ryan was saying

when he was showing us the data.

- Yeah.
- That we've got to get back

about 10 to 12 feet.

You got Shadow Cave right there
in that direction.

You got Weeping Cave.

And then the marsh
is right there

smack in the middle,
so this is really centralized

amongst everything
we've already uncovered so far.

- Right.
- And this is the one

- that's not a clear opening.
- It make sense.

They wouldn't leave
the true opening

just for anybody
to walk by and find.

Derrick: Getting yourself
in the mindset of Aztecs,

if they have something to hide,

they're not gonna leave
a clear opening.

They're gonna cover it.

Dan: We need to get closer
to that and take a look at it.

I'm gonna look here
a little bit,

but, Gina, why don't you go off
to the left?

We almost have
a little indent over here.

- No [ bleep ]?
- Yeah.

Right, well, follow that.
Right here. You see that?

- [ bleep ] yeah, we do.
- Gina: Let me see.

Let's dig this out a little bit.

If we can just pull
a little bit...

- Gina: Skim the top.
- Of the dirt off of here.

- Grab a flashlight.
- Derrick: All right.

You want a shovel, too,
or just flashlight?

Dan:
Grab a shovel as well, please.

Here. Dig a little bit
of that out.

Careful.

Holy [ bleep ].

- It almost looks like a...
- Hand me the flashlight?

Dude, come look at this.

That goes back pretty far.

We got to get in here, man.

This looks like
it's a massive chamber.

A massive chamber. But there's
way too much dirt, man.

We're not gonna be able
to do this by hand.

Derrick: From what Ryan was
saying, 10 to 12 feet back,

you gotta to figure
it's all packed.

Kevin: Hopefully
we got enough light

and we got enough generator.

Chris:
I think we got everything.

Narrator:
After their GPR scan revealed

that the Pit may lead
to a tunnel,

Kevin and Chris have returned
with a plan.

This thing down here
where it's...

Chris: We're gonna go down.
I'm gonna drill four holes.

Load the holes. We're gonna
hook the charges up,

and hopefully blow down that
wall and see what's back there.

I'll be tethered up. Just
in case anything goes wrong,

I'm gonna pull as fast as I can,
get out of there.

It's kind of unnerving
to get down there

and drill this thing,

but we're just gonna take it
inch by inch

and get it done.

Well, here goes nothing.

Narrator: Due to the fragile
nature of the mine,

Kevin and Chris settled on
a low impact expl*sive system

called SierraBlasters.

They will first drill the rock

and place blast rods
into the holes.

The small charges
are coordinated

to fracture the rock face,

causing less shock
to the surrounding tunnel

than a traditional expl*sive
would do.

You ready?

Ready.

- Radio check?
- Check.

- All right, man. I got you.
- Okay.

Hey, anything looks sketchy,
if you're not comfortable,

drop the drill,
drop everything, get out.

- I got you up here.
- Okay.

Kevin: All right.

All right.

Anything looks sketchy,

drop the drill,
drop everything, get out.

Narrator: Chris is rappelling
down into the Pit

to set a series of expl*sives

in order to gain access
to a possible tunnel.

Chris: I just got to watch
this drill on the way down.

Kevin: Yeah.
Please be careful of the drill.

Kevin: I've got a couple
of concerns about this.

One is he's using
a hammer drill,

which not only is it spinning,

it's also percussive
going into the rock.

So my biggest concern is that
he's gonna start

bringing material down
on top of him.

Chris and I are gonna be
in a constant communication.

He's gonna have to talk to me.
I'm not letting him off line.

The moment that drill starts,
everything is in my hands

to make sure that
he comes out of there.

Chris: All right, slow.
It gets really steep here.

Watch your head.

You got the last overhang
before you drop.

Chris: Okay. Right there.

I'm almost at the bottom.

I'm about 80 feet down.
Let me check the oxygen.

Okay. 20.9.

Okay, slow.
This is where it gets steep.

Kevin: I got you.

- Okay, I'm on the bottom.
- Copy that.

All right, Chris,
you're not coming off line.

I just don't trust
the sketchiness of these walls

when you start to drill on it.

Chris: You're gonna
have to give me enough slack,

and you're gonna have to pull
that slack if we need to go.

Kevin: Copy that.

Okay, go ahead
and give me some slack.

Chris: 100 feet is a long way
to be down for a decline

that you can't get up
by yourself very easy.

If anything happens down there,
it's all on Kevin,

and he can only go a couple
feet at a time

to shimmy me up.

That's my biggest fear is how
fast I can get up this thing.

Kevin: I've got you
five by five on the walkie.

I just can't hear anything
else down there.

Okay, I'm ready to plug in
and try this out.

Okay, let me know
when you start to drill.

I just want to keep
an eye on the walls

and ceilings I can see.

Okay, Kevin, I'm ready
to make the first hole.

Copy that. Go easy. Go slow.

Keep an eye on your overhead.

Chris: So I'm drilling holes
in this so I can actually

put the Sierra charges in there
at the right spot.

The worst thing
with this drilling process,

of course, is bringing
a rock down on our head.

Okay, here we go.

So far. I don't have
any dust coming up,

and I don't see anything
rocking out of the ceiling.

Copy.

Copy that. Kev, be careful.

Take a breath.

[ Chris grunting ]

[ grunts ]

Didn't punch through?
Did it seem a little shaky?

[ alarm beeping ]

[ alarm continues ]

[ bleep ]

[ bleep ]

Get out. Get up.

Narrator: Next on
"Lost Gold of the Aztecs"...

You gotta see this, Dad.

We're gonna get
the drill rig in here

and see what we can find.

Dan:
If we find a tunnel system,

to me that says
the Aztecs were here.

Does it mean
the treasure is here?

I hope to God it does.

Hey, uh, looks like
we have something here.

- [ alarm beeping ]
- Come on!

Kevin: We've just got
poisonous gas that came up.

You all right?

That's not gonna be where I die.

So we're gonna have to
build something

to get the air cleaned out.

It doesn't have to be pretty.

All it has to do is work.

- What you guys got there?
- Jerome: Check this out.

This stuff looks like
it was just stacked in there.

Gabriel: I'm hoping to find
that this is a Spanish vault.

This is really what
we're out here looking for.

- Ready?
- Yeah, real slow. Real slow.

Oh! Whoa, whoa!

Hey, take a look at this!
