[narrator reading]

[man exclaims]

[narrator] After triggering
an underground flood

on their first attempt to
drill the energy zone...

Damn, that's
a lot of water.

[narrator] ...the team
was forced to abandon
the area

until the water levels
finally dropped.

[Chad] You can tell,
there's no water running.

[man] Completely dry.

[narrator]
With the area dry,

the team could finally
return to drilling.

Everybody out of the way.
We got the drill
coming in now.

[narrator] In an attempt to
reach the keyhole cavern

under the energy zone.

But after drilling
for two days,

the drill struck
an impenetrable layer

120 feet below the surface.

The further we get down,
there's like black chunks
in there

that are... that we
haven't seen before.

This is the...that
we're drilling through
right now.

That's metal.

[narrator]
Searching for answers,

Duane consulted with
the Quantum team...

Good to see you again.

[narrator] ...who make
a startling discovery.

We found iridium.

Well, iridium means
off-Earth, right?

It's not natural
to this planet.

But it all boiled back to

a meteorite impact.

Well, that explains
why it's so hard

If it was a meteor,
there's no way we can
get through it.

There is something huge

going on
on your property.

We have to find
another way in.

[bleep] boys, that deal
was harder than diamonds.

Whatever is down there,
we're not gonna get
through it.

[narrator] The meteorite
that the team hits

seems to be
approximately

120 feet below
the energy zone.

But it's unclear
how wide it might be.

If it's large, it may cover
the keyhole cavern,

much like a dome.

So I had my dad
call in Eric.

I mean, Eric's off
on his own adventures,

but he's been here
at the range
and helped us a lot.

I'm excited to hear
what Eric thinks
about this meteorite.

Eric, how you doing, brother?

-How's it going, Eric?
-How you doing, man?

Hey, Charlie.
Hey, James.

How's it going?

-Good, how you doing?
-Good, man, good.

[narrator] Geologist
Eric Drummond

spent two years
with the team

studying the strange landscape

of Blind Frog Ranch.

[Eric] I think
we got a meteorite.

[narrator] During his work,
he also found

traces of the meteorite.

It's nice holding
something that...

-came from outer space.
-[man] Yeah.

[Eric] This could be
a major discovery.

I miss you guys
out there, I'll tell you.

Yeah, we miss you,
too, brother.

How are you progressing
with your exploration?

Uh, we've been drilling a hole
over at the energy zone,

and we're hitting
some really hard stuff.

It's even melting
the bits.

[Eric] How deep
was it?

Maybe 120 feet.

[Chad] We brought in
Stephen Leeah.

And he's saying
that it could be

a huge meteorite
down there.

[Eric] Wow.

So if this actually
is a meteorite,

you think we could
drill through with
the right rig?

I doubt it.

Normally, meteorites
are iron and nickel.

And so, they're dense.

But it's like,
really really hard,

but you may be able to

dig down around
the periphery of it.

For example,
I was just back in...

In Ohio,

and I was researching
this area called

the serpent mound
disturbance.

And it happens to be
a meteor impact site.

[narrator] At
the serpent mound in Ohio,

native Americans
built an enormous
snake-shaped structure

on the site of a huge
meteorite impact

that happened over
250 million years ago.

Sites of other
meteorite impacts

have also been marked
in Central and South America

by the Aztecs
and other indigenous cultures

who believed
that meteorites

were the arrows
of the Gods.

More recently,
a giant meteorite
was extracted

near an indigenous site
in Peru.

Could the mysterious
keyhole cavern

be a native American structure

built to venerate
the meteorite structure

discovered by Stephen Leeah
and his team.

[Eric] The serpent mound
disturbance,

it's a three-mile diameter
impact site.

It hit the earth

and it just
fractured everything.

There things hit earth
with such force,

just like a bomb,

a huge bomb
going off, basically.

Not more than
60 miles from here,

is a meteor crater
in Arizona.

And it's created
fracturing

around this large
impact crater.

I actually live down
in that area,

so I've been there
many times,

and there's all these
caverns and fissures

that have been created
by that impact,

that the native Americans
have used for

thousands of years.

Could that impact here
have created caverns as well?

[Eric] Yeah, absolutely.

Um, large cave systems
follow faults,

because there are
weak zones in the earth.

So, Eric, if we're
dealing with this
big meteorite,

and we can't
drill through it,

how else are we gonna
find another entrance

or a way in?

[Eric] I'm just thinking out
loud now, but...

I remember we went
into that mine,

and we saw significant amounts
of bat guano in there.

You remember that?

Yeah. That's right.

[narrator]
Two years ago,

while searching
for an opening

into the cavern system,

Eric discovered
bat guano inside a cave.

That looks to be, uh,
feces from bats
or something.

[narrator] However,
the cave had high levels
of radiation,

and was too dangerous
to explore.

And so bat guano, um...

Is known to be high in
a compound called nitrates.

These nitrates come up
through these fractures,

filtering up
into the soil

and you'll find
these nitrates

towards the surface.

If we can detect
nitrates in the soil,

around these fractured zones
or faulted zones,

that may

provide a clue
to where

we could search
for natural openings.

We could essentially map

this void system by mapping

the bat guano,
of high nitrates.

[narrator]
If the meteorite impact

created underground
fissures and caverns,

one way of detecting them

is by analyzing
the soil above.

If high levels of nitrates
are found in the dirt,

this would mean that
the nitrates from bat guano

might be migrating up

through a fissure or cave.

I mean,

It may sound like
kind of a bat [bleep]
crazy idea.

-[laughter]
-It might just work.

So what do you need
from us, Eric.

You can do this with
very basic equipment.

You'd wanna take
about a...

one kilogram
worth of sample.

So one kilogram
is maybe two

pretty good
handfuls of soil.

GPS in each
and every location.

That way we can get back
to where these samples
came from.

And you can put it
in like a ziploc
freezer bag.

And send them out to me.
I'll give them to a lab.

If you see anything,

out of the ordinary,
if you see fractured rock,

or anything like that
at the surface,

make any notes
that you can on those,

and I'll get them to the lab
and take care of the rest.

Thank for
helping us out,

I'm sorry I missed you
in Las Vegas, New Mexico,

when you came through
but...

I hope to get out there again.

And wish you
all the best.

Thank you, Eric.
Appreciate it.

We got to get
some shovels
and get going,

-huh, boys?
-Yeah.

-[Eric] So get those samples.
-All right.

-Let's go.
-All right.

[Chad] We get
the location, GPS,

grab some bags,

and make sure
it's sealed.

Then we're gonna
head out to
the energy zone,

and kind of fan out.

I'll take
the south side,

y'all take
the other two.

-Okay.
-Then we'll...

-We'll get some samples.
-All right.

-Sound good?
-[all] Yep.

[narrator] The team plans
to collect samples
from four areas

of the ranch surrounding
the meteorite.

Charlie, Duane and James

will cover the north,
east and west

while Chad will take
samples from the south.

[Duane] Are these mountains
getting bigger
or am I getting older.

[all chuckle]

I'll go up here
and grab some samples.

[James] He said about
two good handfuls.

I'd hate to get stopped by
the police on the way
out of here

carrying all these
bags like this.

They'd have
a field day over that.

[Chad] So where
we're going now,

this is like exploring
the dark side of the moon.

So this is the south side
of the energy zone

mountain right here.

This whole area.

So what Eric
was saying is,

the nitrates will
actually seep up

through the fissures

and come to
the surface of the soil

which could lead
to a cavern system.

All we need is
a crack or a fissure

somewhere to be
able to enter.

It's just a matter of time

to be able to
find the right one.

[bleep] boy.

Don't make me
go the south side,

way up there.

Should I get
some samples?

Yeah. They're all marked,
everything graded, yep.

[narrator] The team
collected and marked
20 samples

from the area surrounding
the meteorite,

and will send them to
Eric Drummond's lab

for analysis.

-[Chad] We're set.
Does that work?
-Let's do it. All right.

-[Chad] Hey.
-[Charlie] Wassup, man?

I got some big...
news here.

Now we're talking.

So we just got
the soil samples back.

The east and the west
soil samples were a bust.

But the sample I got
from the south

had elevated nitrate levels.

[narrator] The samples
that Chad collected

south of the meteorite,
and energy zone,

show unusally high
levels of nitrites,

which means
there may be fissures

just below the surface,

where bat guano
is migrating upward

from an underground
cavern system.

Tha shows that
there's a cavern

of bat guano
that goes in there.

And if there's
bats down there,

there's bat guano
all through there,

that means there has to be
an opening at the surface.

I think that this is
like a back door.

We get in right here,
we can track

-all the way to here...
-Come up, right.

[Chad] ...and not have to
go through that

huge meteorite.

[James] The fissure opening
would be near the surface,

so we wouldn't have to
drill to reach it.

[Duane] [bleep] ... man.

Let's just go
get the excavator

and see if we can
find that opening.

Let's go to work.

-[James] Good deal.
-[Chad] Let's do it.

[narrator] In order to get
the 75,000 pound excavator

to the location of
the nitrate deposits,

Duane must first clear a path

through the creek bed
which appears dry,

now that the water levels
have subsided.

[Chad] We got the track-o,

my dad's gonna make
a little pathway

to get across the creek,

so we can get to
our spot, start digging.

[Duane] Charlie, boy,
do you copy?

We have some
serious silt here,

I'm gonna have to
bring some dried...

[Duane] Hell of a mudhole.

I was on solid ground
the whole time.

And then I turned my tracks
and we fell through.

He's trying to build a road

so that we can get
right to the site

where we're gonna
start digging, but...

We might not get
very far.

[Duane] Charlie, boy.

Little bit.
How far am I
to dry ground?

[Ryan] I think
the only digging

we're gonna do today
is digging you out.

-Well, we'll get across.
-This looks...

This looks really bad.
You're about
two-three feet down.

[Duane] Yeah.

[Charlie] Over here.

[Duane] Where in the hell
is "here" at.

That's damn near forever,
Charlie boy.

We might have to
abort this one
and go lower.

Look out, fellas.

Come on.

Come on... [bleep]

[bleep]

[bleep]

Oh... [bleep]

-[Duane] Charlie.
-[Charlie] Yeah.

[Duane] I can't
dig this hole... [bleep]

It's just bottomed out.

Yeah.

[Duane] I'm... I'm... [bleep]

-[Charlie] We're sinking,
all right.
-[Duane] Yeah.

[Charlie] We're going
right Titanic on this [bleep]

[Chad] Holy [bleep], man.

God, almighty.

[bleep] ...stuck. Jesus.

What the... [bleep]

Oh!

[Duane] Yo.

[Chad] What the... [bleep]

-Your six foot in
the ground right now.
-[Duane] Yeah.

I think I hit
some quicksand.

[Chad] That's real bad.

I mean I just don't know
if a two truck
will pull it out.

Can't even see
your tracks.
Tracks are gone.

[narrator] Quicksand is formed
when water becomes trapped

under silt and cannot escape,

and the liquified soil
quickly loses it's ability

to support weight.

And the immense weight
of Duane's excavator

is causing it to sink rapidly.

See that?

[bleep] ...so he's
still sinking, though.

[Duane] We're getting
worse and worse.

I mean,
we were solid.

And now,
it's just like, we're...

There's an undercurrent
of muck.

Yeah. Probably got about
four hours left

and this summabitch
gonna be completely under.

-Thanks for being
a cheerleader, Charlie.
-[Charlie] Yeah.

I'm trying to get a signal
to call the tow truck.

All right. Here.
Here we go.

[Duane] I can sense some mud
coming in on my feet.

[Charlie] You know,
there's an old saying.

That the captain always
goes down with the ship.

-Yeah.
-[Charlie] And I'm damn glad

I'm just a first mate.

Yeah.

'Cause I always wanted
to bring you up.

-[chuckles]
-[Charlie] I...

I don't want a promotion.

[laughing]

All right, we need to
get a move on,
we're sinking.

[trucker] All right. 10-4.

Hey, what's the, uh,
ETA on that truck?

He didn't know,
but he said he's coming.

The vibration
of the engine

is causing it to sink

probably about an inch
or so every ten minutes.

If they're not here
in the next 30 minutes or so,

we're gonna be out about

-a half million dollars.
-Oh.

We gotta get
my dad out of there,

before the whole thing sinks
and he can't get out.

Hey, man.

I just got over here,
what's going on?

[Chad] [bleep] Man,
he obviously...

The main problem is,
this is quicksand.

And as the engine's running,
that vibration's just
making it sink

every five minutes
it's another inch.

We're... We're screwed, man.

Why does he have to
keep it on?

Because, well,
if he shuts it off,

all of a sudden, there's
flooding in the engine,

The air filter's [beep] wet.

-Yeah. And you won't be
able to start it back up.
-You can't start it back up.

Then you have
a 80,000 pound acher.

[line rings]

Hey, yeah, this is
Chad Ollinger.

We're waiting on the tow truck
down here at the ranch.

All right, uh...
Okay, thank you.

[bleep]

Forty-five min... I don't know
if we have 45 minutes.

[Duane] Look at it
wiggle, Charlie.

It's serious jiggling.

I mean, there's something
don't have a bottom to it.

[Chad] Hey!
[bleep] huh?

This thing's getting
deeper, man.

Stop moving it around,
you're just making it
sink faster.

-[bleep] in the cab?
-[Charlie] Yeah.

[Chad] Yeah, look at that.
Look how much she's
already filling up.

[Charlie] Yep.

It's going down fast.

[Duane] If they don't
get here pretty quick,

we are [bleep].

There ain't no doubt
about that.

They're still out
45 minutes.

[bleep]

I can't get the [bleep]
out of here...

[Chad] Oh, we got
a big boy, hell yeah.

Yep.

Yeah, that's a winch truck,
isn't a tow truck, it's good.

This thing's big.

Howdy, man.

Hey, my dad's
stuck in the cab,

we gotta get this thing
out of here, ASAP.

[trucker] I can see that.

Right here is, uh,
where he went down.

[trucker] All right.

[Chad] He's uh, six foot deep
at the minimum.

Yeah.

That's big.

Thanks for
coming out, brother.

Now I got
a winch truck coming.

[Chad] He's gonna
slowly pull you.

Guys, we need to
watch out for this cable.

Thing snaps,
we got big problems.

[engine revving]

All right, here it goes.

There you go.
Hell yeah.

We're moving.
We're moving.

All right, it's sinking.

[inaudible] ...down,
going deeper.

[trucker] Hey, what?

What's happening is,
his nose is getting
more buried.

So what do you think,
if he pushes down,

lifts his front end up,
and pull him like that.

Whenever you get
pulled forward,

you're bearing
your nose.

So if you can
push down,

keep your tracks up.

If it doesn't emerge,
we have to break the glass
and pull him out.

[narrator] While attempting
to pull the excavator
out of the quicksand,

the backside has sunk deeper,

pushing water
into the engine.

[Chad] Is there any way
you think we can...

If we can just
scoop that up,

lay it right up there.

-[Duane] I can't stand.
-You have to.

-You scoop it... right there.
-All right, all right.

All right, I'll do it.

[narrator] Chad's plan
is to use the bucket
to dig out

some of the quicksand
in front of the excavator,

creating a clear path
to winch it forward.

You're unhooked.

...now is, uh...

He's pushing
all this mud up,

and that's just more
force and weight.

So he's digging out
in the front of it,

getting it out of the way
and building up a road
in front of us.

So, uh, we'll have
a better chance
to pull him out.

Just close to you.

Perfect. Yeah, exactly.

There you go,
yeah, perfect.

Yes.

All right, everyone,
clear out, guys.

Here we go, boys.

Yeah, we're moving.

Yeah, here you go.

Yeah!

Yeah! here we go.
Yeah, let's move
this... [bleep]

Hell, yeah.

[engine revving]

[bleep]

So the good news is,
we got it out of
the main sinkhole,

the quicksand.

But the problem is, now,

is he's just pushing
a [bleep] of mud.

And he's having
a hard time keeping
his nose up.

All right now, I'm...
Uncovering the tracks.

These guys want to
rig up a chain,

it goes on the outside
of the tracks.

So I got to
unbury the track,

see how wide it is.

I don't know if
I can get to it, man.

It's so [bleep]
under there.

Oh [bleep]

[exhales]

[bleep] tracks
to that way.

Oh no.

[speaking indistinctly]

[narrator] With the tracks
in a perpendicular position,

the winch truck is pulling

75,000 pounds
against the grain.

[Chad] Now we got to do
the same on the other side

[trucker] Oh yeah.

[bleep]

That was the process.

[narrator] The tow team
will need to latch on
to the tracks,

to drag it
out of the creek.

[Chad] I don't think
we'll find that one.

[trucker speaking
indistinctly]

[horn beeps]

That'll do.

[bleep] you want me
to help you or not, bro.

[bleep]

All right, my man,
Wayne's got two winches.

Not one, but [bleep] two.

We got one hooked up
to the boom.

Tracko.

Trying to pull the tracks
tthrough the second winch.

The secone excavator track
was too deep under the mud,

so we can only get
one hook on it.

But hopefully,
it will be enough to
pull him out of there.

Here we go,
we got hitched,
boys, watch out.

Ho ho!

Push down.
He's not pushing down.

Push down.

Down.

There! There!
Hup! Hup! Hup! Ho!

Whoa! Hold up,
you're pulling me over.

I think that's
our only hope.

Let's...

Let's find the other track.

-[trucker] Yeah.
-We'll dig it up.

All right.
Have him pull me.

[Chad] Y'all ready?
Here we go, boys.

[engine revving]

That thing's trashed.

You're gonna have to
take it apart

and clean the whole thing.

So the guys were able to get
the excavator out of the mud.

That's the good news.
But the bad news is,

the excavator's
totally wrecked.

Here's the thing,
we wanted to

get over there
as fast as possible.

'Cause we got
a full day of digging
right there.

So we got
major problems now.

Hey, has anyone
seen my dad today?

Do you hear that?

Duane! Nice work!

[Charlie] Back in
business now.

That right there
is like Duane Ollinger,

'cause he will
always pull a rabbit
out of his hat.

[narrator] Duane arrives
with a replacement excavator

and gets right to work.

That thing was sinking
like [bleep]

[narrator] To avoid
any further issues,

he takes it the long way
around the creek.

The plan is to
excavate an area

of loose rock
at the foot of the ridge

where the highest levels
of nitrates were found.

Damn.

Stop. Let's start
digging over here.

[bleep]

Hey! Stop! Stop! Stop!
Hold on! Hold on!

Hey! Let's get it here.

[Chad] Look at this.
There's a cave,
there's a opening.

[narrator] Excavating
at the site of high-nitrate
concentrations,

Duan has punched into
some sort of cavity.

[yelling excitedly]

[Chad] Oh my God.

James, we got something!

Oh I feel that breeze
coming through.

-Really?
-[James] Yeah.
It's cold.

[Charlie] Damn.
I can feel it up here.

Get it open.

[grunting]

[grunting]

[James] Be careful.

[Duane] Look at that,
Charlie boy.

[Charlie] [bleep] cold there.

[Chad] I told you guys,
there's something in here.

I think this is a tunnel.

[Chad] [bleep] Head is
in the cave right now.

[Charlie] That goes right back
in there, doesn't it?

Oh, yes.

That's a real honeypot,
right here.

But be careful,
that whole [bleep]
could cave in on you.

[Chad] This is tight.

I got it.
Here you go.

[panting]

[bleep] Goes way back here.

-Y'all feel the breeze?
-Yeah.

The breeze is getting
even stronger in here.

[narrator] The last time
the team felt such a strong
flow of cool air,

was the collapsed
mine entrance out at
crow creek.

Guys, you can feel cold air
coming out from down here.

Are you [bleep] me?

[Chad] Oh man!

This is wild, man.

[grunting]

This goes way down in here.

[Chad] No, it's
crawl space for a while,

but it looks like it's...

opens up 'cause
there's a huge echo.

[Chad] Yeah.
Yeah, we're fine.

Whoever dug this...
It's a solid cave.

It sounds like it.

[Charlie] We need to get
some equipment up here.

[Duane] We damn sure do.

[narrator] The team plans
to explore the tunnel

to see if it might be
an entrance

to the keyhole cavern,

where they believe
a cache of Aztec gold

might be hidden.

We need to watch out for sure.

-Sounds good.
-All right.

[narrator] After getting
their gear and flashlights,

the team returns
to the cave.

Nah...

[narrator] Veteran cameran
Joel Schwartzberg

will accompany the team
into the tunnel

to document
what they find.

Okay, boys,
here we go.

Let's do this.

[James] Is there
enough room in there?

Is it a lot?

[Ryan] Any
standing water or...

[James] Joel's gonna
follow your [bleep] in there.

-[Chad] Oh, that's right.
-[Ryan] Same system.

I don't [bleep] know
if I'm gonna fit
through that.

[Ryan] The water's
like ice back here.

I'm seeing frost.

[Chad] [bleep] yeah.
It's icy.

[Joel] Hey, man.
I cannot turn around here.

Hold on.

-[Ryan] You gotta turn around.
-[Joel] Ah!

[Chad] Not a good time
to be claustrophobic.

-Hey, Skinner.
-[Ryan] What's up?

There'e no way
I'm gonna get in here

with the backpack
and the magnetometer in it.

It's super-tight
back here, man.

Let me hand it to you.

-[Ryan] Can you
hand it up, James?
-[James] Yeah.

[Joel] Oh... Seriously,
I can't even turn.

Oh my God.

[panting]

My God, this is tight.

It is.

[groaning]

Is it bigger in there?

'Cause it's pretty
[bleep] tight now.

Jesus, it is tight.

[Joel] I'm starting
to get claustrophobic.

[Ryan] Okay. Go...

[Joel] I gotta
get out of here.

[Chad] We're together.
We'll die together, bro.

[Joel] Not good.
It's not about that,
I gotta get out of here.

[narrator] Joel is
having a sudden attack
of claustrophobia,

an intense
feeling of panic

brought on by
the tightness of the cave.

[Joel] I really gotta
get out of here.

-[Joel] Yeah.
-[James] All right.

[Ryan] Go, let's go.

[grunting]

[Chad] James, come...
Come on up here.

-[Joel] James.
I gotta get out of here.
-[Chad] Joel is gonna go up.

[Ryan] There's an opening.

[indistinct conversation]

[narrator] The team tries
to keep Joel calm.

[bleep] My ankle.

God, this is
too [bleep] small
for four people.

[narrator] Finally,
James is past.

Joel can now crawl
toward the exit.

[Joel] Jesus.

[panting]

It's me.

[Joel] There you go.

[man] Got it.

[Joel] I gotta come out.

Jesus.

[exhales]

It's more tighter
than it looks, huh?

It's [bleep] tight.

[panting]

But it's really [bleep] tight.

[narrator] After spending
a few minutes in a wider
section of the tunnel,

Joel has recovered
from the panic attack.

[panting]

[narrator] He is able
to head back into
the narrow passage.

But this time,
crawling in backwards

to avoid having to
turn around in
the tight space.

There's another chamber
coming off of here.

Oh yeah, it's another tunnel.

[Chad] Oh!

[narrator] The team has
belly-crawled 25 yards

into a cramped void

where the passageway
splits into two
different tunnels.

But the second tunnel
is even tighter than
the one

the team has just
squeezed through.

I saw a quartz vein
that you guys passed up.

[Chad] Really?
So this could be

a vein or some kind of,
like, bank,

like a storage area
or more like a...

It had to have been mined
and it's got to me
a depository too.

Remember, this goes for
hundred of miles everywhere.

Look at this [bleep]
It's everywhere.

[Chad] Yeah, we don't have
any idea how far this goes.

[Ryan] You can
hear it open up...

-Yeah.
-[Ryan] ...into
something much larger.

[James] Could the Aztecs
have discovered this
years ago

and used this to hide?

This is just
one entrance of many.

And you gotta
think about,

if they've been
looking for this
for hundreds of years,

it's not easy
to find.

We're gonna have to
go through this.

[Chad] [bleep] ...still going.

Can we fit?

[Chad] It opened up back here.

I see a huge [bleep]
cavern here.

-Holy [bleep]
-You see?

It's opened up like...
and drops off.

[bleep]

[groaning]

[laughing]

Holy [bleep]

[James]
Look at the mineralization.

Look at the water ponds
that are carving through.

It's creating that
carbonic acid.

It's eating the cave.
It's a live cave.

[narrator] Carbonic acid
forms from rainwater

and carbon dioxide
in the air.

A relatively weak acid.

It dissolves softer rocks
like limestone,

carving out caves
and cavern systems

wherever the two compounds
come into contact.

[James] Hello.

[laughing]

Get in here.

Holy [bleep]

It's frikkin' massive.

We are the first people
to see this,

possibly in hundreds of years
if not thousands.

[narrator] After squeezing
through 50 yards

of pitch black
subterranean tunnels

beneath Blind Frog Ranch,

Chad and the team

have emerged into
a massive cavern.

[James] This is huge.

Oh my God,
look at this.

This is exactly what
we're looking for.

[Chad] These are giant logs.

[James] Why are there
logs down here?

[Chad] Oh my God! Look it!
Look at it. Look it.

This is actually huge.

This is... This is...
Somebody made this.

-Is that man-made?
-It's man-made.

[Chad] You're kidding.

-[Ryan] It's cut out...
-[Chad] On my God, it is.
It's cut out.

[Ryan] Why is it
down here?

[Chad] Damn,
wonder how far it goes.

Look at that.

-This means
somebody was in here.
-[Chad] Yeah.

This is exactly
what we're looking for.

-[Ryan] How old is it?
-It's weak

Feel that...
The wood gives.

[narrator] The hewn logs
are evidence

that ancient people
have utilized these
caves before.

But they are far too large

to come through
the narrow tunnel
the team entered through,

suggesting there might be
a larger tunnel

hidden somewhere
in the cavern.

[Ryan] Do you guys see
any openings?

[James] I don't see
any way out of here.

Yeah, dead end right here.

But how the [bleep]
did this wood
get here though?

This looks like
it's the end right here.

[Rayn] It's gotta keep
going down.

[Chad] Gotta make sure.

This is the end
of the tunnel right here.

It's just, uh, all jammed up
with mud and rocks, and...

Check to see if there's
a vertical shaft somewhere.

[Ryan] The fact that
we're in a chamber
this big right now,

that water had to go
somewhere.

It's not just gonna stop here.

It's gonna keep
drilling it's way down.

[James] It's like a...
a drain.

It's topped up right here.

[bleep]

It sounds hollow.
Did you hear that?

-[James] You can.
-[Chad] You can feel it.

[James] You can feel
this whole ground
up here, moving.

Do you think maybe
it was covered up?

[Chad] Like a false bottom.

[Ryan] You hear that [bleep]

-You can feel it. You can...
-[Chad] Yeah,
you can feel it here.

There's something...
There's something
along here.

-[James] Yeah.
-Hundred percent.

[James] Look at this.
I mean all the [bleep]
built up here.

There's got to be
a continuation.

You know there could
have been passageways

taht were just
sealed up,

because of
all the runoff this year.

[Chad] We just don't know
how far these rocks
go down... you know.

'Cause this could be
a whole another
entrance right here.

I think you're [bleep] right.

I think that's
the next spot to go.

This just might go
into another whole cavern.

We need to regroup
with your dad

and then figure out
some technology to
get down here

and maybe break...

-Break down into.
-[Chad] Yeah.
That's probably a good idea.

This is what we've
been looking for, finally.

We've hit so many
dead ends and wrong turns,

but also so many clues.

It's taken us years...

It's getting stuck.

...and so much hard work.

It's a marker.

But we finally found
an entrance to
the cavern systme.

That gold is down here.

And we're gonna find it.

This is amazing.

This is the closest
we've ever been.

[groaning]
