03x02 - Underground Tsunami

[bunniefuu]

[narrator] Previously, on
Blind Frog Ranch...

Duane Ollinger assembled
a new team,

to help him breach
the cavern system.

What the hell are you doing?

[narrator] And to find
the treasure.

I'm bringing on an expert.

James Keenan,
he knows more about ancient,

underground cave systems
than anybody out there.

[James] There's
this cavern system.

They've got to connect
to what's under
Blind Frog Ranch.

[narrator] But they discover
trespassers illegally digging
on their property.

[Duane] Where's your boss
at, slick?

[Chad] Someone came in here
and dug an ill*gal hole
on our [bleep] damn property.

They're trying to find
the [bleep] treasure we are.

Get this [bleep]
outta here, boys.

[man] Call the law,
right now. Call 'em.

[narrator] Then,
the team learns startling
new information

about the ranch.

We did two analysis.

Duane, what you're staring
at is the Doppler shift.

I've only ever seen that
in super massive black holes.

[narrator] Which revealed
what might be
an underground chamber.

That's a series of caverns
and tunnels.

That's gotta be a cave.

That circle under the
energy zone looks man made.
No doubt.

[narrator] And a landmark
of an ancient Indigenous God
known as Towats.

It's this natural formation
that looks like
an individual's head.

He's their creator
that's guarding something.

What the hell
is he protecting?

Biggest treasure ever.

[narrator] Blind Frog Ranch
stretches over 160 acres.

A remote and rugged area
in northeastern Utah.

It's a place
shrouded in legends
of ancient civilization.

-[Chad] Wow. Look at that.
-This has to be
hundreds of years back.

[narrator] And a
mysterious phenomena.

[man 1] There's some kind
of dark force.

[man 2] We got something
really weird here.

I've never seen anything
like that.

[narrator] Duane Ollinger has
owned Blind Frog Ranch for
over a decade.

Convinced that the land
holds secrets.

What the [bleep]?

[narrator] And a massive cash
of Aztec gold
hidden underground.

We're sitting
on something huge.

[narrator] Rumored to be worth
more than $3 billion.

Your ranch is part of most
famous treasure hunt that's
never been solved.

[narrator] But every time
he's gotten close...

[Duane] [bleep] look at that.

[narrator]
...the land fights back.

What would eat
the head off of it?

-Whoo!
-[man 3] I'm flagging red.

-Close your mask.
-Let's get out.

Go! [bleep] go!

[James] All right, gentlemen.
I brought you out here
for a reason.

[Duane] So
what are you thinking?

We're standing on a spot
that's a cash site for
treasure and gold.

We have our expert
James Keenan
helping us out here.

He has more knowledge
than anybody I've seen,

and I know he can help
me find this treasure.

[James] I mean, look around.

There are no
[bleep] banks here.

Where's your vault gonna be?

Underground in the caverns
that the quantum scans found.

[narrator] A few days earlier,

after scanning
the 160-acre ranch
and analyzing the images,

Stephen Leeha
and his quantum team

identified an area
of unusual phenomena.

I've only ever seen that
in super massive black holes.

[narrator] As well as
a keyhole shaped cavern.

That's a series of resonances
that we've seen before inside
known tunnels.

That's gotta be a cave.
That's what it is.

And it looks like
a cave to me.

[narrator] Researcher
James Keenan believes

the keyhole cavern
could contain

the lost Aztec treasure.

Somewhere below our feet
where we stand

could very well be a chamber
filled with treasure.

What do you need
to protect a vault?

A fortress,
this big freaking
geological castle.

You have that high point
up there.

You have this battlement
station up here
and behind us.

So if you think about anybody
coming in from the north

from the south, from the
west or from the east

you have this easy
defensive positioning
to protect the treasure.

[narrator]
According to legend,
500 years ago

when Spanish conquistadores
invaded the Aztec Empire
in Mexico,

the Aztec king
sent his gold and riches
to modern day Utah.

Considered the ancient
homeland of the Aztecs,

where it was hidden in
deep underground caverns.

We're talking about eight tons
of gold and treasure.

-He kind of knows
some [bleep] .
-Yeah, he does. Nice.

You're right about this
being a really great fortress

that they can defend
everything from here,

'cause I've been
all over this thing
and it is absolutely safe.

Where do we start?

This natural formation
over here that looks like
a Native American's head,

Towat.

According to local
oral histories
that I've researched,

the Head of Towat

potentially sits above
a chamber filled
with treasure.

And when you look
at that quantum map,

you have this structure
underground that
looks like this key

that runs right under
the Head of Towats.

[narrator] Towat is the Native
American God of protection,

mentioned in rare manuscripts
and local lore,

but never authenticated.

Through his research,

James Keenan believes
the landmark he's identified
on the ranch

is a representation of Towat.

The original entrance
of the caverns has gotta
be around this area.

-Somewhere where they overlap.
-Makes sense.

James, this is
what we've been needing.

So, we need to do
a systematic grid search

for anything
that looks like an entrance
that was filled in.

I got a better idea,
why don't we just
find that thing from above?

Get Chad to run Cessna
and do a couple flyovers.

That's a hell of a lot faster.

This boy's a champion
crop duster from way back.

He's a crack of Jacks.

So he can spot
anything we need to see.

This is exactly why I brought
James onboard here.

He's the guy
that can take the legends
and the science

and find us a way
to get that treasure.

This is amazing, James.
Let's get to it. Let's go.

-[James] All right.
-Let's do it.

[narrator] The search area
near the Head of Towats

is approximately
one square mile.

Chad will fly at low altitude,

looking for any geographical
irregularities that could
indicate a potential entrance.

Holy [bleep].

Roger that.
Yeah, it's pretty windy
down here.

Can you go do a south to north
over the Towats?

And then an east to west
or west to east?

You said he was


You can hear him,
he should be here any second.

[plane approaching]

[Duane] There ya go.

-[James] Oh!
-[all laughing]

[James] Could've reached up
and grabbed on.

He'll never get that [bleep]
outta his system.

[Chad laughing]

[bleep] damn.
Man, this is [bleep].
It's great.

[James] Could've knocked
your hat off your head.

There's the ranch right
in front of us, right there.

So we're gonna get a hell
of a shot at Towats,
bird's-eye view.

Oh, [bleep].

Feel that?

The turbulence
is so hardcore right now.

It's hard even
to keep it level.

Jesus Christ.

It's like there is something
trying to push you back
as we get close over Towats.

That's wild, man.

It's almost like he doesn't
want us to be here.

I keep flying over
and it's pushing us away.

Oh! [chuckling]

Holy [bleep]
this is rough up here.

-[James] He's looking
a little shaky up there.
-Chad, knows what he's doing.

If I ride with anybody,
it's damn sure gonna be him.

We're doing a couple
of east to west passes,

but I don't see anything
that looks like an entry.

All right,
so we turned around,
go back over the ranch.

I'm gonna pass back over,
then we'll bypass this b*tch,

and then we'll, uh,
get some good shots
from the side.

Whoa.

[narrator] Chad has discovered
a potential site

at the southern end
of the Head of Towats.

Just above the keyhole
formation that the
quantum team

identified in their scan.

-[Chad] We're
at five right now.
-[James] That's amazing, Chad.

That's exactly what we were
looking for.

Good work, Chadbo.

All right, I'm heading back.
That's a good place
to start looking.

All right, gentlemen, we have
our map here.

And this is Towat,

as you can see, right here.

Chad's possible cave
is right here.

It's almost like
the throat of the God.

Now watch this,
when we line up

Stephen Leeha's quantum photo,
check this out.

It looks like a keyhole cavern
is just under Chad's cave.

Yeah. Jeez.

So I know where the cave is,
it's just right around
the corner over here.

So we can go down the creek
and look for an entrance
covered up.

We'll just look for something
that's been backfilled.

[narrator] According
to local folklore,

after Aztec warriors
hid the king's treasure
in Utah,

they filled in
all the entrances
to the cavern system

so that it would not
be stolen.

The cave that Chad
spotted from the air

appears to match
this description.

The team
will head to the location

with the possible
filled in entrance
to take a closer look.

-Let's do it.
-All right.

-It's right up here.
-[James] Here? All right.

-[Chad] I think this is it.
-[James] All right.

That does look like
a recessed area.

It looks like it's just
been piled back up.

Like, backfilled.

Looks to be an entrance
into a back area.

So this is all soft dirt.

It looks like
it goes back in there.

[narrator] The cave mouth
Chad spotted from the air

appears to be backfilled
with hundreds of cubic feet
of soil,

which could take weeks
to excavate by hand.

That's just a...

-crap ton of work by hand.
-Yeah. Right.

So here's what we'll do,
we'll just blast this whole
son of a buck out.

We'll pop that,
then we'll dig that ash out.

And that, uh, powder out.

[James] Yeah, I agree.
Let's go do that.

[Duane] Jack, here's where
we're gonna pop the first one.

Right down in that ravine.

We brought in, uh,
these dynamite experts.

So they're gonna be loading up
the filled in cave entrance
that I saw with dynamite,

and they're gonna
have a controlled demolition.

[Jack] It looks like
a natural cave opening

that just back backfilled
with river mud.

I can make hand charges
and sh**t that out

and see how much rock there is
to get up into that cavern.

Perfect. Let's do it, fellas.

See what we got here.

Sandstone right there.

-[Chad] Braced right up, huh?
-[Jack] Yeah.

[narrator] To clear the area,

the demolition team
plans to remove the top layer
of soil by hand,

and then place three
small 10-pound expl*sives

that will detonate
the remaining dirt outward.

We should be able
to blow all this loose stuff
right outta here...

-[Chad] Yeah.
-...so we can see, you know,
what's under there.

The idea with the dynamite is,
just to blow the loose dirt
out of the cave.

The ledge overhead
is solid rock

so the easier path
for it to go is outward.

[Chad] We're ready
to rock and roll.

-So that's all of it
right there, huh?
-[Jack] That's it.

-[Chad] How much is that?
-Ten pounds.

[Duane] If there's a hole
behind all that sediment,
we should blow it wide open.

It sure is damn exciting.
This could be the way
into our cave system.

[Jack] So we're gonna
set three of these in,

but we wanna keep
the integrity of all this,

'cause ideally
this is gonna be our entrance
walking in.

[Chad] Okay.

-We're gonna put some mud
over the cones.
-Oh, okay.

[Jack] And that helps direct
that energy down.

Okay. We're good.
We're golden.

[Chad] We're stringing
this all the way
up to the cabin

to get far away,
so none of the debris
gets to us.

Big rocks and other [bleep]
blowing up.

All right,
everyone get to a safe place?

[Jack] You ready to do this?

All set, boys.

[air horn blasting]

Three, two, one.
Fire in the hole.

-[Jack] Boom!
-[Chad] Whoo!
Holy [bleep]!

[Chad] Three, two, one.
Fire in the hole.

-[Jack] Boom!
-[Chad] Whoo!
Holy [bleep]!

Boom! Whoo-hoo-hoo.

-Do you hear that?
-[Jack] Charge fired
successfully.

-[man mimics hissing]
-Yeah, what was that?

[man] That was weird.

[Charlie] Oh, hell,
Lookit, this fell.

-[James] Wow.
-[Chad] Look at that [bleep].

[James] Man.

[Jack] Yeah,
it hit pretty hard.

[Chad] Yeah,
you could feel it.

[Jack] Oh, man.
So the top fell down.

[Charlie] So we gotta move
all this [bleep] outta
the way, then.

All that rock fell down
just from the shockwave.

That's a lot of trash.
We've got a bit
of a complication.

The force of the blast
knocked off a big chunk
of that ledge.

[narrator] Instead of blowing
the dirt outward

the force of the expl*si*n
has travelled upward,

collapsing the overhanging
rock above and covering
the area in debris.

You know, uh, I think I can
get that trackhoe down here,

that'll help us understand
if we got into
the tunnel there.

[trackhoe beeping]

[Chad] We just blasted
and we have tons
of rock to move,

so we're gonna
bring down the trackhoe,

take a few scoops,
get all that [bleep]
outta there.

I've been spotting for him
since I was a little kid.

I was probably like six
or seven years old.

Whenever my dad
was babysitting

he'd put me
and my sister on a crane
in this open filed,

we'd just play around
with the crane

and that was how
my dad babysat us.

If the caves
can give us access in,
it's gonna be huge.

So that's exciting as ever.

This is very likely
one of the best shots
we've had.

[rocks scraping]

That's solid rock, son.

Well, I was hoping
we'd hit dirt
in all that rock.

That rock is just...

-[Jack] Too hard.
-Too hard, yeah.

Well, I damn sure dug
as far as I could. It's solid
rock right there, fellas.

You could tell by the drag
in those teeth it ain't there,
it's not there.

I've been digging
the soil out,

there's no hope behind
it or below it.

It's just more solid rock.

I really want to get us
into the cave system,
so, you know,

this is a little bit
of a bitter pill to swallow.

[Chad] Oh, man.

My guess is, this formation's
just limestone all the way
across here.

So this is sure not
their original entrance.

[Chad] That's just about
as disappointing
as you can get, right there.

[narrator] After failing
to find an entrance
to the keyhole formation

under the Head of Towats,

Duane and the team regroup
to discuss their next move.

[James] Where we're standing
is this circle.

And the false cave
is over there on the left side
of the circle cavern.

We just gotta get
some more information
to figure out our best shot.

So we can do that
by foot, right now.

Run the magnetometers over.

That can, hopefully,
go at least 60, 70, 80 feet
into the ground.

And bring us back, uh,
a pretty decent picture
of what's below us.

[narrator] James has proposed
conducting a grid search

of the area
with a magnetometer,

a device which measure
the magnetic fields emitted
from the earth.

And can detect
geological features
and voids underground.

I think that might help, too

to maybe narrow it in,
to give us the best

noninvasive underground
picture of what we have below.

You give us a mark
and we'll bring in
the trackhoe.

-[Chad] Sounds good.
-[James] All right.

We're gonna grid it
right here.

[narrator] To preform
the magnetometer search,

James and Chad
first plot out a grid...

-Ten right there?
-Ten right here.

...to help them
track their position
above the keyhole cavern

shown on the quantum scans.

We're just
powering it up right now.

[narrator] James will then
scan the ground
in half-foot increments,

looking for signs of a void
or anything that might suggest
a hidden cave opening.

Come on, James,
find that tunnel.

[machine beeping rhythmically]

[narrator] The grid search
is a painstaking

and time-consuming process.

Each step must be precise

so as not to miss
any critical data
on what lies below.

-How deep does it go?
-One hundred
and thirty-two feet.

My magnetometer locates
differences in the localized
magnetic field.

Any reducing
in the magnetic field
means that that's a void.

And that void
could very well be
a cave entrance.

So did you find
some cool [bleep]
down in Mexico?

Yeah. I, uh, located
a metal object inside
the pyramid at Tula

with this exact magnetometer.

-Really?
-Unbelievable find.

[alarm blaring]

-You found something?
-Yes.

This is odd.

-There is a void right here.
Look at that.
-[Chad] [bleep].

[James] There has been
a hole there before.

-Huh.
-Right here.

-Can you grab the paint?
-Yeah, yeah.

[James] So we gotta mark
this spot.

There is a straight drop
right here with no soil.

This could be
really significant.

[Chad] Yeah,
we better tell everybody.

[James] We've got
some new data to share.

-[Duane] Let's hear it.
-[James] Okay.

Chad and I were running
the magnetometer,

we did the grid pattern search
and right over here
in this quadrant,

we had an anomaly.

And if you look right here,
what it's showing is that,

there was a 38.23
meter hole of sorts.

Very small, only within
a square foot area.

It's really interesting,

when you look
at it in three dimensions.

-[Duane] [bleep]
-Yeah. So we have
the surface up top.

And we have what
appears to be a vertical
shaft of sorts.

If you look
at the quantum scans,

there is a cavern right
below where the shaft is.

I don't think it's natural.
I think this was man made.

-[Charlie] The shaft?
-The shaft.

If we have some type
of underground cavern system,

what are they
gonna have to do,
to be able to breathe?

-So you're saying,
that could be a vent?
-Exactly.

That may have been
a man made vent
for whatever's underground.

-[Chad] Just air flow.
-To get air flow
down underneath.

[narrator] The top
of the 130 foot vertical shaft

is 15 feet below the surface.

And sits directly over
the keyhole formation below,

where the team believes
the treasure might
have been cashed.

Experts believe the Aztecs
constructed shafts
like this one

to ventilate
underground chambers.

In 2003, archaeologists
unearthed a similar

60 foot shaft
at Tenochtitlan,

the Aztec empire capital,

which is thought
to have been used
for subterranean ventilation.

[Duane] James said
he found some kind
of vent shaft

that leads some
100 feet down.

And he'll take a long
time to get down to.

Oh, I know that plateau.

-It's all hard packed dirt.
-How do we get down there?

[Duane] Once we blast
that dirt off the top,

we should be able to dig
down there and find that...

[narrator] The 15 feet
of hard-packed dirt

that covers the vent shaft
will require the expl*sive

power of dynamite
to crack it open.

What might take days
with a drill,

can hopefully
be accomplished
in hours instead.

If it's a small vent
with blasting effect,

that vent would close it up.

Yeah. It can be
a surface blast.

Just to crack that sweet candy

with... with tiger
teeth on it.

-It should be okay.
-We have to get in there.
No matter what.

We need to get in there.

Let's get some dynamite
and blow it.

-Let's go.
-[Duane] All right.

[Chad] Right down here.

[James] Yeah, this is it.
This is the hole.

[Chad] This X is where
James found the spot.

So right here, when we
hit it with the magnetometer,

it seems like it was some
type of shaft,

-that has just been
covered up over time.
-[Duane] Interesting.

[narrator] Duane and his
team have called in
dynamite experts,

to help them open up
a suspected
Aztec vent shaft,

leading down to a mysterious
keyhole shaped cavern.

They'll need to remove
around 15 feet of dirt,

to reach the top
of the 130 foot vent shaft.

So my plan is to do
a 10 foot diameter
circle pattern

with X in the middle,
marking the spot.

-[Duane]
Copy that. Let's do it.
-[all] Let's do it.

[man] Let's paint
some rocks
to make the circle.

We're ready for the drill.

[narrator] The team will drill
16 holes around the shaft,

and place dynamite charges.

[man] Let's get
that drill down here.

[narrator] If all goes
according to plan,

the detonation will expose
the top of the vent.

[air hissing sound]

[man] Hey.

I need you to replace
the gasket. One's just
blowing out real bad.

Light that b*tch up.

[man] Yeah,
that's better.

Nice move, boys.

So we've got 16 holes there,
marked, ready to drill.

'Kay. Good to go.

[man 1] That was quick.

-Just the last
hole right there.
-Just one more.

-[Chad] Look at that.
-It's muddy.

Let's have a look.
Oh, man.

What do you think?

-Yeah, the problem
is that it fell--
-Caved in.

It filled in.

-Get that water.
-Oh, man.

[Chad]
It's filling up the water.

So the strange part is,

as we drilled all
these holes,

and it was dry powder
coming out.

And that last hole,

that's where we
got the water, and it just
flooded all of 'em.

I mean, this is a big problem.

Like, if these holes
keep filling up water,

they'll be hard
to get the dynamite
down at the bottom,

so we can get a good blast.

[man] We're gonna get
these holes loaded,

precise as we can.

This was dry powder
when we was coming up.

That was dry dirt.

[man] This hole's... I think.

Damn.

[narrator] In order
to get expl*sives
into the drilling holes

before they fill
with water and collapse,

the team will attempt
to re-drill

and immediately insert
the expl*sives

as the drill is removed.

We thought we were
already gonna blow this,
probably, two hours ago.

But, uh, we're still waiting
to plug the dynamite

and so it's taking forever.

[man] Oh, that's on it.

Those cuttings were
dry coming out.

I don't get it.

I'm gonna mount the pole.
You get in there fast.

Come on, baby.

-Come on.
That's it. That's it.
-You got it. That's it.

-Beautiful.
-Yeah.

All right, you guys.

We're loaded
and ready to go.

Let's get these vehicles
out of here. I gotta
string a line out.

[man over radio]
Copy that...

'Kay. sh**ter is live.

Stand by
for countdown right now.

Three, two, one.

Fire in the hole.

[bleep]

-The line didn't sh**t
though, did it?
-It might have.

It could have blew
a part of your connection.
I don't...

That's the only thing.

[Chad] That was weird.

That we're shot the line,
and it didn't connect.

This is exactly the [bleep]
I was talking about.

We have live dynamite out
there that's not exploding.

[bleep]

I ain't checking
that fuse, man.

Babies in there
good and tight.

I cut both. Checked both.

All right.
Good, good, good.

'Kay. Stand by for countdown.
Here we go.

Three, two, one,
fire in the hole.

[all exclaims and laughs]

[Duane] [bleep] Finally.

Three, two, one,
fire in the hole.

[all exclaims and laughs]

We started blasting right
under the head of Towats.

This is exactly where
James' magnetometer

found the shaft,
the underground caverns

that were seeing
on the quantum map.

[James] We have
what appears to be

a vertical shaft of sorts.

-That was cool,
-Good work, everybody.

[Chad] We got some
depth in there, huh?

[James] Well, he blew
the [bleep] out of it.

[Charlie] So we got
fracture rocks right here.

But we just need
to clean this out.

Straighten down in there.

So Jack was not
in my crew.

He did a good blast.

But now we got a lot
of loose material there.

We gotta clear
the hole out.

Oh, [bleep].

[bleep]

[James] Wow.

-Oh, man.
-[Chad] Damn.

That's a lot of water.

You can see that we hit
something when we're drilling.

And this whole
area is flooded.

How the hell did this happen?

[Duane] I don't know.
There's something going on.

[narrator] After blasting
and excavating
to reach the vent shaft,

the team finds the area
is flooding with water.

It seems to be seeping up
from underground.

[Charlie] Hey, guys.
Come here.
Let's check this out.

The holes the trespassers
dug are all
full of water down.

Water everywhere.

[Chad] This whole thing
is super unstable.

[Charlie] That's ready
to collapse, right there.

-[indistinct]
-[Chad] Yeah.

[Charlie] Whatever we hit,

seems to be affecting
the entire ranch.

'Cause there's just...
There's more water
that I've ever seen.

Those trespasser holes
filled up with water

and it was...
it was really, way too fast.

[James]
That's a [bleep] of water.

[narrator] The team discovers
water levels rising in areas
throughout the ranch.

Including the holes
dug by trespassers.

And even the pond,

where Duane has attempted
to breach the caverns
in the past.

With water flooding the ranch,

Duane and his team need
to reassess their plan

to excavate
the vent shaft area.

Oh, yeah. There's no doubt
something's going on here.

Hell, hell.

I've never seen that much
water coming through
on the system like this.

Yeah, even the guy
who was drilling

said he'd never seen
anything like this before.

You know, maybe the snow melt,
raised the water table.

That's way too fast
for snow melt.

Did we crack open
a underground river
or something?

More like an
underground tsunami.

You know, it's a lot like,
what we see
in Mesoamerica.

It's not out of the realm
of possibility

the Aztecs created some
type of water traps
to secure the treasure.

Like a booby trap,

that they set
underground for this?

The Aztecs were
masters of creating

aqueducts and passage ways
at Tenochtitlan.

This is something they
were fully capable of doing.

[narrator] The Aztecs
were master water engineers.

Able to create
ingenious aqueducts
and flood control barriers.

They even built
their capital city,
Tenochtitlan,

in the middle of a massive
2,000 square mile lake.

Could they have used
their mastery of water

to create an aquatic trap,

at Blind Frog Ranch
to protect their treasure?

Well, whatever it is,

it's pouring water
into every hole
we have out here.

We have no dry access
anywhere inside.

But here's the deal.
This is from the quantum
map right here.

Here's where we drilled,
right there.

And it flooded.

But it also flooded
at the pond
at the same time.

What if there's a direct
connection from
the blast site to the pond?

Maybe we can get
to the keyhole cavern
from the pond.

[narrator]
Three years ago,

the crew tunneled
under the pond
on Blind Frog Ranch

and discovered
an underwater cavern.

And a mysterious
timber box.

Chad, now wonders
if the pond

maybe directly connected
to the cavern beneath
the blast site.

And that diving into the pond,

might be an alternate way
into the keyhole.

But previous dives
into the pond have
proven dangerous.

Making Chad's proposal
a risky one.

You know how it is, son.
That's pretty damn
dangerous down there.

Let's think about that before
you go back down in that deal.

More than, I'm like, concerned
to have going back down
in there again.

We don't know what
the currents are right now.

We don't know
what damage
has been done.

Yeah, I mean,
I know it's dangerous.

But we're shut down
over there for now.

I think we have to go back
in there, 'cause that's our
number one lead.

[Duane] The pond's
dangerous.

You got waters
that are coming
in even worse.

And I sure don't want
to see Chad get hurt.

But, you know,
Chad will do what he does.

Um, like I taught my son,

you're supposed to do
what you believe is right.

I've always said,
if you start, you finish.

Who am I to stop,

when I made my child

not get the capability
of stopping?

All right, son.

We'll put tether on you.
You go check it out.

-We gotta get
in that [bleep].
-All right.

[James] The hell's up
with the color of it?

[Duane] We gonna find out
once we get in there,
I guess. But...

Yeah.

[Charlie] So the massive
flow of water coming
through here now,

the currents is what
concerns me.

If Chad goes down in there,

are we gonna be able
to get him back out?

[Duane] So here's what
we need to do, son.

We'll just get over that hole
and you drop straight down.

With the current down there,
it could get real nasty.

[James] Yeah, first time
I won't push you
too hard.

We'll just check it out.
Check the hole.
See what's in there.

Just drop down,
come right back out.

[narrator] To understand
why the water
level has risen,

and whether there
is a connection to the water
flooding the energy zone,

Chad and team are preparing
for an exploratory dive

into the pond cavern.

All right. So we'll
keep tension on it.

Not too much, so we
could still float around.

But you never [bleep]
drop the rope.

-Two pulls, call everyone
and pull me out.
-[James] Okay.

[Chad] I'll have Joe
with me down there.

But you're my lifeline.

[James] Oh, wa--
I don't know if that was
a tug or not. Hold on.

Duane, you see anything?

[Duane] He's just
dropping straight down
the hole right now.

[Charlie] Okay.

[indistinct talking
under water]

[Chad] Something just
[bleep] touched my leg.

There's something
swimming around in there.

[James] Well, [bleep].

[Charlie]
Don't give him...
Don't give him much slack.

I won't. I'll keep
the tension pretty tight.

-Duane, is he okay?
-[Duane] I don't know.

[Charlie] He might
be in the current. [bleep]

[Ryan] I [bleep] lost him.

-[James] Where's his bubbles?
-[Ryan] I can't see
anything in here.

Pull him up. Pull him up.

-I'm pulling.
-[Duane] Double tug.

Double tug, James.

Double tug.

Duane, I'm double tugging
and I have him.

But he's locked
up on something.

Help me, Charles. Pull.

[Duane] [bleep]

[Charlie] Right behind you.
Right behind you.
Right behind you.

Bubbles coming up.

-[James] There you go.
-Are you all right?

[Chad] [bleep]
tugging me in.

[Chad exclaims]

So you're down there.
Find the hole.

And it has like,
tons of trash
and [bleep] in there.

It has a huge current in it.

It starts sucking me,
kind of down there.

-[Duane] That's
the trespasser's tent?
-[Charlie] Yep.

[James] Chad comes out
with a sopping wet tent.

How did it get down there?

Maybe one of the trespassers
dropped it in their hole.

And then it went through
the underground
system and came up.

They're sure as heck
not camping underwater.

Chad, get your a*s
out of the water.
That's enough of this.

[bleep]

It sucked me in.
And then I felt
y'all pulling.

I think if we go back down,
we can [bleep] dig
a little bit out of it.

[Duane] I think
you're full of [bleep].
Get out.

I know Chad well.
He can handle himself.

But, he's my son.
I don't want him

or anybody else to get hurt.

[narrator] The danger
of being swept away
by the strong current

is too great
for Chad to risk
further exploration.

[Chad] It's gnarly now.

The risk is gone way up.

I'm scared that if I got
sucked out in there,
I couldn't get back out.

That current's coming
from the blast site.

[narrator] However,
Chad's made
an important discovery.

The underwater current
is flowing away
from the keyhole.

And toward the pond.

Which seems to confirm

that there is a connection
between the two sites.

A series of caverns
extending under the ranch,

all the way
past the pond.

[James] The current's
underground.

Means there's potentially
miles of caverns
underneath Blind Frog Ranch,

that we've yet to explore.

So, is the underground
system connected?

I've been telling
people for years,

that the answer is, yes.

And that may just
be another freakin' clue

to what's going
on underground.

That means this whole
cave system's flooded.

So, we got to find new ways
to get in there somewhere.

You start, you finish.

We don't have a choice
about quitting.

We've started this whole deal.

And we're sure as hell
going to finish it.

[narrator] Next
on the Mystery at
Blind Frog Ranch...

If we excavate here,
we might find
the cave entrance.

[man exclaims]
That was a close one.

Hold on, boy.

[man] Come on.

[man exclaims]

[Chad] Hey, guys,
you ready to drill?

[man] Drill, baby, drill.

Go [bleep] cave now.

[bleep]

Y'all have to come
look at this.

Look at this. Whoo-hoo.

Finally get to hold
gold in my hands.
