[narrator] Previously on "Blind Frog Ranch."

[Ron] You gotta get out of the armchair

and you gotta follow the history.

Treasure hunter, Ron Feldman,

is attempting to use a Mormon pioneer's journal

to locate an entrance into the Keyhole Chamber.

And after discovering a passage that points

to the outskirts of Blind Frog Ranch...

-[beep] -[Eric and James] Oh!

[James] Look at that.

Josh, Eric, and James...

I think we're at the entrance of a mine.

...located a collapsed mine entrance...

[Josh] Eric, you ready to break some ground?

I've been ready for five years now.

...they believe will lead to Aztec gold.

[James] [bleep]! Whoa!

But their underground quest

has taken a costly turn.

[Eric] Guys, it's caving!

Oh [bleep]! Run!

Legends of ancient treasures...

It could go thousands of years back.

-...and unexplained phenomena... -[grunting]

Oh [bleep] this! I'm not messing with that.

...meet at a 160-acre property

in Northeast Utah,

known as Blind Frog Ranch. - [croaking]

For decades, teams have searched the land

for long-lost Aztec gold.

But the closer they get...

-[James] That's it. -[Eric] Look at that!

-That's gold! -[James] Yeah.

...the harder the land fights back.

[Josh] Whoa! The hell's going on?

Now, a prolific miner...

We're standing on a pile of gold.

...and a legendary treasure hunter...

There must be another tunnel entrance, something.

...armed with new evidence...

-[Chili] Look at this. What the hell is that? -[James] What'd you find?

...and a fabled artifact...

[Ron] There's a date on that --1912.

...will take on a 500-year-old curse.

Fire in the hole!

And a land littered with traps...

-Go, go, go! -Whoa, whoa, whoa!

...to find a three billion dollar treasure.

[James] Oh!

They won't stop until they've uncovered the mystery

of what lurks below...

[Eric] Guys, it's caving!

Oh [bleep]! Run!

...at Blind Frog Ranch.

[mystery music plays]

[Josh] Eric!

Eric!

[indistinct]

Back up, back up, back up.

Can you see him?

[Chili] We gotta get to him.

[Josh] I need some tools. [bleep]!

I need shovels. I need picks.

Now! Now!

♪♪

[Chili] [bleep]! Watch this top right here.

[Josh grunts] I need some wood for support for this side.

[Chili] All right, hold on.

Eric!

[Josh] Eric!

[Eric] Josh! Josh!

[Josh] I think I hear him.

Eric, we're coming. [panting]

[grunts]

[Chili] Gotta push through.

[Josh] There he is.

[grunts] Come here.

-Come here. -[Chili] Get to him.

-[Josh grunts] -[Eric] Watch my leg, my leg!

-[Josh] You hurt your leg? -[Eric] Yeah -- over, over!

[all grunting]

-[Josh] Easy, easy, easy. -[Eric] Aah!

[Josh] Watch out. I almost got you.

-Look out, look out. -[Eric grunting] Yeah.

-[Eric coughs] -[Josh] Hold on.

[both grunting]

-[Josh] All right, buddy. -[Eric] Let's go.

[Josh] Eric is really lucky that he got out of there

with just a few scratches, um.

That could have went a completely

different direction.

-[Chili] Let's sit him down over here. -[Eric grunts]

[Josh] Sit down right here, buddy.

This is a huge issue. We're gonna --

we're gonna have to rethink everything right now.

But we've come too close to stop now.

We have to find a way through this thing,

no matter what.

Let's clean it. Let's muck it.

Keep on going. [sighs]

The Blind Frog Ranch team is hunting for lost gold.

They've unearthed a mine entrance,

they believe leads to the Keyhole Chamber

and the legendary Aztec treasure.

-[Chili] This is a big slab, it broke off. -[Josh] It's gonna be tight.

In an attempt to avoid another collapse,

Josh and demolition specialist Chili

are working to reinforce the entrance. -Keep going.

[Josh] The collapse was a scary setback,

but Eric did see multiple passageways forward.

So right now, we're gonna go in

and investigate these passageways.

[Chili grunts] There. That should do it.

[Josh grunting] Here. Another one.

-[Chili] Give me that one. -[Josh] A chunk broke off.

[Eric] Our goal is to get back into this drift.

It's very important.

That could be where the treasure is.

So, I'm going to bring in some big machinery to help me do it.

♪♪

[Eric] Come back a little bit this way.

All right

Six hundred yards from the drift,

Eric plans to conduct a resistivity survey,

a scan that uses electrical currents

to determine geological features

such as voids or tunnels.

He's hoping this will help guide the team safely

into the tunnel system, past the collapsed area.

[Eric] A little bit more.

That should be good.

The drill team will drill holes deep in the earth,

where Eric will place electrical rods

that can scan a wide portion of the area

near the mine portal.

[engine shuts off]

-[Thomas] How are you? -[Eric] Good, how are you?

-Thomas. -Eric.

-Eric, nice to meet you. -Jared.

-[Eric] Jared, Eric. -[Jared and Eric] Nice to meet you.

Thanks for coming out.

We're going to be doing what's called

an electrical resistivity survey.

So I need you to drill several 30-foot holes,

spaced at about 20 feet apart.

[Jared] Yeah. We can do that.

So, my plan is to use, uh,

rods connected to an electrical source,

to give an underground picture of what's beneath the surface.

So I'm going to use this technology to find a way

to get past the collapsed portion

of the underground, uh, passage.

How are we doing there, Jared?

[metal clanking]

About 30 feet.

OK, let's -- let's -- let's pull it up

and move it out.

We're going to drill three holes,

and we're going to put rods into each of the holes,

and we'll connect the wires to an electrical source.

Signals sent between the stakes Eric planted

create a current in the earth.

As the signals pass through the ground,

a receiving device measures any breaks in the current.

Using this data, a 3D image is created of the area,

revealing any voids below.

The higher the resistivity,

the bigger the void is.

And that, to me, indicates

it may be much safer to get in there.

So what I'm hoping to see --

I want to see very, very high resistivity.

We just string this out.

We ran this wire all the way from the cave

all the way to here.

-[Thomas] That's our start. -[Eric] That's our start.

-That's where our current is going to come from, basically. -Oh, yeah.

[Eric] So now we're going to put our receiving electrodes in.

Perfect. Solid.

We got 25 more feet on top of that.

And then you put in another receiving probe,

and the amount of current that gets to that probe

can tell you whether or not there's a cavity underground.

You got about 30 foot in the hole.

Then our last step is just hooking all the wires up

to the unit, and we'll see what we get.

So we've got some bad stuff going on in that drift,

and so we don't want to go back in there until we know exactly

where we have to go.

And when you put all this data together

and do a modeling of it,

it can give you a very detailed 3D, uh, image

of what's underground.

Looking at the results of our resistivity survey,

and, uh, our first of three probes or receivers --

it appears to be the area of the, uh, the cave-in.

So you see intermediate, uh, levels of resistivity.

What we want to see is very high levels of resistivity.

That indicates that this electrical current

cannot pass through the void.

It has nothing to -- to go through.

And so when I move between the second and third receivers,

I see that resistivity just jump up.

It goes from like, I don't know, 1,500 up to like 20,000,

and that's ohm meters.

And so number one, that tells us there's a void there.

And number two, as we go to the next probe,

it's even greater.

And so not only is it showing us

that there's a huge void down there,

but it's also descending.

So with this information we have here,

uh, this gives us a map, essentially,

uh, where Chili and Josh can get right in

and get down in there, follow it,

and hopefully get into that Keyhole Chamber.

-[Chili] You ready, buddy? -[Josh] Yeah, I'm ready.

[Chili] Let's do this.

Less than a mile from the Keyhole Chamber,

the team heads back into the drift

with the resistivity results.

[Josh] We've cleared up a lot of the rubble

from the collapse and shored up the entire area.

And Eric's resistivity test shows us

that there's a more stable tunnel ahead of us.

So we're gonna follow that.

We're going in. Let's just keep our eyes peeled

for any bad areas... -[Chili] Yeah.

-...any bad spots. -If you see some

uh, sketch, just call it out. -[Josh] Yeah.

-[James] For sure. -[Josh] Yeah.

[suspenseful music plays]

[Josh] All right. Here we go.

I'll go first.

[grunting]

[Josh] One move at a time, but just keep moving forward.

[James] Right behind you.

-[Josh] Chili? -[Chili] Hold on.

I'm coming.

[James panting] How's it look up there?

-[Josh] It's really stable up here. -[James] OK.

-[Josh] It's still going. -[Chili] Oh, man.

[Josh] It's still going.

♪♪

[Josh] We can stand up all through here.

[James] OK.

[Josh] There's just all kinds of little passageways.

[panting]

[James] Yeah. Oh, man.

-It's just -- -[Josh] It's good.

[James] It's just a long corridor now, it seems like.

[Josh] Yeah.

I mean, now that we got that all shored up back there,

we're in really good stable rock.

[grunts]

[panting]

[James] Which way?

[Josh] Well, I'm looking at the resistivity scan.

Up here to the left,

there's a passageway that way.

We've got two more passageways

up here to the right.

And then there's a trunk that's heading this way,

kind of veers off to the left, though.

It's only showing me maybe 60 feet past the collapsed area.

But it's helping right now.

And I'm thinking that this one passageway right here,

that seems to descend faster.

And that's what we need, we need to get depth.

[Chili] What are we waiting for? Let's get going!

[panting]

[Chili] Watch your step there.

[Josh] We're still going into the unknown.

We don't know what's down there.

And all these different passageways,

we can get turned around.

We've got to be very, very careful.

When you're underground like this,

your mind just gets turned around.

You don't know direction. You don't know where's north.

You're not sure if you came from this way or that way.

So it's very important that we stay calm

and keep track of that.

[Chili] Man.

-[James] [bleep]! -[Josh] Look at this.

It's a big skull back here.

Oh [bleep].

2 [Josh] [bleep]! Look at this.

Jeez. It's a big skull back here,

a lot of bones, too.

It's huge. This looks like --

This is livestock right here.

One hundred feet beneath the Earth's surface,

Josh, James, and Chili traverse

the main underground passageway,

they hope will lead to the Keyhole Chamber.

They've come across what appears to be

an animal skull.

[James] What are you thinking?

[Josh] I think this could be a mule skull.

[Chili] That means they're -- they were doing a work in here.

Heavy work.

During the 1800s,

mules were the preferred pack animal for mining.

They are small enough to easily navigate mining tunnels,

yet strong enough to carry hundreds of pounds

on their backs, making them ideal

for moving large amounts of ore out of mines.

[Josh] This animal most likely lived his whole life

here underground.

That was common back in the old days.

They'd put livestock in the old mines.

-This one didn't make it out. -[Chili] Yeah.

Keep your eyes peeled. Keep looking for stuff.

[Ron] The guys have been looking into the Keyhole Chamber

for quite some time.

I have to figure out what is the team going to do next?

Where do we go from here?

As the team searches for the Keyhole Chamber,

Ron is digging further into the journal.

There has to be more places to look for this Aztec gold

than just the Keyhole Chamber.

In doing research in the past and present -- what I'm doing now,

there seems to be some consistency

to the number seven.

Ron's research has revealed the possible existence

of more than one Aztec gold chamber.

Chicomoztoc is the mythical birthplace of the Aztec people

and is depicted as a series of seven caves.

Ron believes the Keyhole Chamber

could be one of those seven caves

and is trying to determine which of the other six

to search for next.

I'm going to look into every single map,

all the information, uh, in this journal.

There are six more chambers of gold that we need to find.

[somber music plays]

A lot of symbols here.

This resembles some of the canyons that I'm seeing.

They're showing these pine trees.

And -- and these maps don't seem to relate

to where the team is now looking for the Keyhole Chamber.

They're different places.

And what was interesting is these inserts.

Uh, three of them here.

They seem to be very old,

written in some kind of a language with a map here.

It may be Deseret, the Deseret alphabet.

Deseret is a writing system

created by Mormon settlers in Utah in the mid-1800s.

Used for only a short period of time

within such a small group,

it is often referred to as a hidden language,

making it excellent for writing secret messages.

If something was written in another language or a code

with a map,

my treasure-hunting senses are always up.

It was done so, because he didn't want anybody else

finding out what he's trying to designate in the map.

These three really stand out

because the languages seem to match,

and certainly you can tell

that they were written by different people,

which tells me multiple people have taken the time

to copy this passage.

This is unique, and the code is something

that has to be cracked,

'cause I think this is of great importance.

We got to find out what this says.

James knows a -- a professor in Salt Lake City

that is -- uh, knows a lot about the Mormon history.

Maybe see if they might be able to decipher this.

I think this is the one that we need to take.

This one doesn't have the depiction of the map.

We don't want anyone to see that map if it's important.

[somber music plays]

[James] Oh man, it gets pretty narrow right here, huh?

[Josh grunting] Yeah, just a little bit.

[James grunts] [bleep].

Ah.

Approximately 200 feet underground

and beyond the map provided by the resistivity scan,

Josh, Alex, and James have been investigating passageways

for almost two hours.

-[Chili] Hey, Josh. -[Josh] Yeah?

[Chili] How much further do you think we're going?

[Josh] Well, we don't exactly have the exact footage.

Um, we just know that this was the longest channel,

so we're just gonna take this till its very end.

[Chili] Watch your step there.

[Josh grunting] Big step, climb up there, James.

[James] OK.

[Chili] Hey, guys, get over here! Check this out.

Look at this.

-[Josh] What the hell is that? -[James] What'd you find?

Well, that's a pictograph.

[Chili] So how old do you think that is?

Oh, I don't know.

I mean, God, it's definitely --

it's not Mormon.

This looks older than the Mormon symbols we found.

It could go thousands of years back,

maybe even indigenous.

[Josh] Just keep pushing forward.

[James] Oh!

Oh, it's getting even tighter, huh?

[Josh grunting] Yeah. You doing all right, James?

[James grunting] Yeah, I just got to -- get through.

-[Josh] James, look right here. -[James] Where?

[Josh] Right here. There's another --

there's another marking right here.

[James] This is an X or a cross,

so, I mean, it could mean anything.

Looks like whoever made that one,

made this one as well.

And this is definitely an ochre mixed with some type of clay,

so I'm thinking Native American or even older.

[Josh] I mean, somebody was in here marking this trail.

[James] Hell, yeah, for a reason.

We need to keep going.

[Josh] All right.

[Chili] It opens up over here.

-[Josh] It opens up? -[Chili] Yeah.

-[James] Oh, yeah. -[Josh] Yeah, it does.

-[James] Holy crap. -[Josh] Look at that.

It's got, like, a nice archway.

-And it's a straight shot. -[James] Hell yeah.

Whoa, whoa, whoa. What's this right here?

-[Josh] What you got? -[James] Look at this one.

[somber music plays]

[James] This one I do recognize.

It looks like the marking that the indigenous people

used to do.

What they would have symbolized as death.

[Chili] That's no bueno.

I don't like death.

[James] This is not a good symbol to be finding back here.

So I'm kind of worried what's gonna be up front,

what we're gonna find.

For thousands of years,

indigenous cultures have painted messages

onto cave walls.

These petroglyphs form a hidden language,

and each symbol carries a specific meaning,

understood only by other members of the tribe,

including directions, predictions, and warnings.

For tribes native to the Uintas,

markings like this are considered a warning sign,

indicating danger ahead.

[James] So, you know, maybe just as a precautionary measure,

let's take it a little bit slower.

[Josh] You mean you're saying we just need to watch our footing?

I mean, they wouldn't have put traps in here

or something like that.

[James] I don't know.

I mean, only the person who made it

knows why they put it there.

There's no question that people have been in here

before us.

We're seeing symbols on the walls.

But that last one, James says

he's seen that used as a death symbol.

That doesn't sound so good.

-[sighs] All right, well... -[James grunts] Oh.

...there's only one way to go.

That's forward.

I don't know who put them in here.

I don't know if they're ancient.

I don't know if it's Walkara himself

or people after Walkara.

Heck, it could have been the Mormon.

But there's a reason.

They weren't put in here for nothing.

It narrows up, up here, guys.

[grunting] Oh.

[James] Oh, yeah.

[Josh] Yeah, we're going to be on hands and knees.

We're going to have to crawl through this section here.

I'm going to switch lights.

I'm going to go to my floodlight so I can really

see the rock, make sure it's still staying sturdy.

[James] You got to be careful.

We have no idea what's under there.

When you're on your hands and knees,

you stick your head in there,

hopefully nothing sticks its head back out.

[Josh chuckles]

[panting]

James, I think we should have left you at the truck.

All right, here we go.

You guys doing all right?

[James] We're crawling.

Ah.

♪♪

[Josh] Holy [bleep].

We got a big room up here.

Whoa!

[somber music plays]

It's got to be 60 feet.

[James] Look at this.

[Josh] This is like a -- massive room.

Guys, is this what we've been looking for?

[adventurous music plays]

2 [Josh] We've got a big room up here.

Whoa. It's gotta be 60 feet.

This is like a -- massive room.

For 17 years, Duane Ollinger and his team have searched

the Uintas for Aztec treasure.

Now, they've descended 300 feet beneath the ranch

and discovered a large chamber.

[James] Man, this place is big.

[Josh] Yeah, look at the size of this room.

-[James] What's in the back? -[Josh] Where at?

[James] Looks like another -- way back there, look.

-[Josh] Is there another -- -[James] Goes up.

[Josh] Another passageway?

-[James] Looks like it. -[Josh] Oh, it is.

-[James] Can we go up? -[Josh grunts]

No, it's caved in.

Oh, yeah.

So my question is --

are you thinking this is the chamber

you guys have been looking for...

-It's possible, huh, James? -...sometime, James?

I think it's possible.

[Josh] Let's just see how big this chamber actually is.

[Chili] I'm gonna pace it out.

[Josh] I mean, we're around 70, 75 feet long,

and our width -- this is a little tougher here.

[panting]

75 by 35, somewhere in there.

[James] And what, like 60 feet high?

I mean, those measurements are pretty close

to what we expected the Keyhole Chamber to be.

[Chili] If this is it, where's the gold?

[mystery music plays]

Based on our location, I think we're in the Keyhole Chamber.

But I don't see any gold. Just dirt and debris.

We've got to be missing something.

-[grunts] Hey, James. -[James] Yeah.

[Josh] Look up above you, on that ledge.

-[James] Yeah. -[Josh] Right to your right and down.

-See all those sticks up there? -[James] Yeah.

[Josh] Water's gotten at least that high recently.

It looks like water's flowing through here.

In fact, I think this chamber gets full of water at times,

I'll bet you it's coming right from here and then filling up.

This chamber was filled with water, uh, just recently.

For years, Duane believed the pond

and other underground waterways on Blind Frog

could connect to the Keyhole Chamber.

We have to find another way in.

And the team's discovery

that water once filled this chamber

supports his longstanding theory.

[Josh] It looks like water's flowing. All this dirt in here,

And we don't know how far it went down.

I'm wondering if it goes deeper.

[Josh] Under the dirt?

[James] Covering something up.

Last year, the year before, this thing was probably

totally filled with water.

And the water brought in tons of dirt.

It's covered the entire cavern floor.

We need to see if there's treasure underneath this dirt.

Get that magnetometer out and see what you see.

[buzzing sound]

[deep buzzing sound]

[James] There's something right here.

[buzzing sound]

[deep buzzing sound]

-There again? -[James] Yep.

But it's pretty deep.

[buzzing sound]

Guys, we've gone in far enough.

The distance is right. The bearing is correct.

We're way the hell underground.

You're hitting metal objects in all this dirt.

This has to be the Keyhole Chamber.

[adventurous music plays]

I agree.

We're standing on a pile of gold.

If this is what we all think it is,

we need to go get a lot of tools.

We've got to dig this whole freaking room out.

Everything we've done has led us to this point.

We think this is the Keyhole Chamber.

We could be standing on top of a giant treasure right now.

We've got to come back here with tools.

We have to excavate this entire room

and see what's underneath all this dirt.

And this is what we -- this is what we've been after

for all these years.

And I think we -- we're right on the edge of it.

♪♪

-Well, I'll get Duane up. -[Josh] OK.

All right.

Back above ground, the team is meeting with Duane

to share their potentially monumental find.

[grunts] Let's see what we got going here.

[Josh] He's gonna be excited to hear this.

Duane's been trying to get into this Keyhole Chamber

for years, and to be able to tell him

that we got in there --

this is big for us.

After all these years, he was right.

We got some news for you.

We got past that blockage, that big boulder in there.

Chili blew it up for us.

Uh, we continued on in.

Uh, and we got into an area that there is a large room.

And I'm telling you,

this could be the Keyhole Chamber.

Duane, can you see my screen?

All right, here we go.

Look at that.

See the size of that room, Duane?

[Josh] That's at least 60 feet above our heads.

So that floor is totally buried.

Many feet.

[James] Yeah, it's a lot.

Uh, we're gonna have to

do a full-out excavation of that chamber.

[suspense music plays]

So we're gonna bring in metal detectors,

we're gonna set up lights, and we're just gonna take it

layer by layer, Duane.

This is where the real work starts.

We're gonna head back into the chamber,

we're gonna use a LiDAR scan,

and we're gonna excavate it inch by inch.

And if we're lucky, we're coming out

with a whole lot of treasure.

We will leave no stone unturned, I promise you.

Everything has led to here.

-[Josh] We got a lot of work ahead of us, don't we. -[James] Yeah.

2 [Josh grunts]

[Chili] Did this get smaller than last time?

[James] I bet, for sure.

Hundreds of feet below the Earth's surface,

the team is heading back to the cavern,

they believe, could be the Keyhole Chamber.

[Josh grunts] A lot harder

with all this equipment, isn't it?

[James] Whew.

This time, accompanied by Eric and equipment

to begin their excavation.

-[ground rumbling] -[Josh] Hey, did you guys hear that?

[Chili] What was that?

-[Josh] You hear that? -[Eric] What was that?

[ground continues rumbling]

[Josh] Sounds like something rumbling underneath us.

[somber music plays]

-[Josh] It's crazy. -[Chili] Heard it.

[Josh] Just for a second

that felt like an earthquake.

[tense music plays]

[Josh] I don't -- I don't like that underground --

hearing that. -[Chili] No.

-That time to get out? -[Eric] No, hell no.

-[James] Hell no. -[Josh] We ain't getting out now.

[Eric] We're going for it.

[Josh] I mean, nothing's fallen. That's a good sign.

Maybe it's the thunder gods.

[Eric] All right, let's keep going, but very carefully.

[Josh] We're not sure if that was an earthquake, or what,

so we're going to take it real slow.

Just be as careful as we possibly can,

but the thing is

is what could lie ahead of us,

this is why we're here.

So we're going, no matter what.

[Eric grunts]

All right.

Here we go.

[grunts]

All right.

[grunts]

[Josh] I think this is the Keyhole Chamber,

but I'm not seeing any gold in here.

What I am seeing is a giant pile of dirt.

We're gonna use LiDAR to help with this excavation.

So Eric's gonna bring in the machine,

and he's gonna get all the dimensions of this chamber.

[whispering] There we go.

Wow.

[normally] Look at -- oh, my God.

I just -- I just looked straight up.

This is crazy.

This has got to be the Keyhole Chamber.

I mean, it looks like there's multiple tunnels going off.

I'm gonna get that LiDAR,

and I'm gonna start mapping this.

So this LiDAR -- what I can do is scan this entire area.

It provides a detailed map of this.

One of the things I'm seeing here

is you're seeing a lot of rubble.

There could be something directly below us

that's been covered up by this -- this debris here.

So there, I'm starting -- it's starting -- it's imaging.

So I'll start low, basically, to get the floor

of the cavern. -[LiDAR beeps]

And then I'll just work my way up.

LiDAR, short for light detection and ranging,

fires thousands of laser pulses every second,

measuring distance at each point

to build a precise 3D map of the terrain.

This handheld system

will generate a detailed 3D rendering

of the entire chamber,

a crucial historical record the team will use

to map out their excavation.

[Eric] The LiDAR will help us plan out exactly

where we need to dig under the dirt rubble.

I'm gonna --

call it good right there.

Gonna switch her off.

There we go.

We have our map.

[Chili] All right, let's find something.

All right.

With a LiDAR scan of the Keyhole Chamber complete,

the team will begin their excavation,

looking for gold, artifacts, or voids underground.

I'll get my metal detector out.

I'll see if we can find any kind of

metal objects in this dirt.

So let's just take it down piece by piece.

Absolutely.

[Josh] We have to excavate this entire room

all the way down to the bedrock

and see what's underneath all this debris and all this dirt.

We could be standing on top of a giant treasure right now.

The team will deploy two key tools to guide their first dig.

Josh sweeps the ground with his metal detector,

flagging any signs of buried metallic objects.

Go up here a little bit.

While James monitors a magnetometer,

tracking subtle shifts in magnetic fields

that could reveal disturbed soil

or hidden voids below the surface.

[warbling tone]

[Josh] Here, we'll get it this way.

[warbling tone]

Got a hit here.

Once a target area is identified,

the team moves in,

stripping away the earth slowly

and methodically, layer by layer.

[Josh] We can't just auger into the floor

straight from the magnetometer hits.

Every scoop of soil is a step backward in time,

where a few inches could encapsulate centuries.

So it's one small pass after another,

just one layer at a time,

'cause we don't want to miss a thing.

[James] Oh, oh, oh. What's that? Look.

[Josh] That's iron.

It's a huge nail. It's a spike.

[James] Look at it. It's oxidized,

like, completely through.

Look how rusted that thing is. It's been in here a long time.

That didn't just come from the hardware store,

I'll tell you that. -[James] No.

That's definitely got some age to it.

Yeah, I mean, we're 1870s on back.

-[James] Yeah. -That's not gold,

but it's a good sign.

[James] We're on the right track.

We found this bolt here while we were digging,

and the time frame, you know, was more than likely

within the last 100 or 200 years,

and it just makes me think

that we have to keep digging in this area,

'cause there's got to be other things here

that we need to find.

Ah.

-What the hell is this? -[hollow thud]

-You hear that? -Yeah.

[hollow thud]

Oh, look at that thing. It's pretty big.

[James] Can you find the edges?

[Josh] Whoa.

That's what I'm going for.

-It's still going. -Yeah.

-It's all the way down here. -It must be.

[Josh] Chili, maybe take the pick.

Pull this away this way.

[James] All right.

[Chili] Dude, that's super long.

[Josh sighs]

Yeah, that's the end of it right there.

-All right. -[James grunts]

[Josh whispering] OK.

[normally] Look at that. What the heck is that?

2 [adventurous music plays]

[Josh] What the hell is this?

-You hear that? -Yeah.

[hollow thud]

[Josh] Oh, look at that thing. It's pretty big.

Hundreds of feet beneath Blind Frog Ranch,

the team presses on with the excavation

of what they believe is the Keyhole Chamber,

hoping the Aztec treasure is finally within their reach.

[Josh] Look at that. What the heck is that?

Somebody brought this in here.

-Look at this thing. -Oh, yeah.

-Oh, right there? -[Josh] Right there,

right there, right there. -[James] Right there, yep, yep.

[Josh] That looks like an old nail.

[James] Look at that [bleep].

That's a hand-forged square nail.

-Yeah, super old. -[panting]

It's very old.

I mean, this is 19th century for sure.

I say we save this entire piece for Eric.

-[Josh] All right. -[James] What a hell of a find.

[Josh] That means there's more stuff to be found in here.

We just found this piece of wood in the chamber,

and it's got a nail in it.

And that tells me one thing.

That means that modern people were in here doing work.

I don't know if it was a scaffolding

that they were building.

I don't know if it was some sort of a sled

that they were using it so they can bring in heavy stuff

back all the way back here,

but it means that there was something important here

and maybe it's still here.

[James] Man, how long have we been fricking doing this?

[somber music plays]

I think there's something scratched in here, James,

it looks like an etching. -[James] Really?

-I think this is a number. -[James] A what?

A number on --

[Josh] That looks like a 5, 3, 1.

And there's something -- something next to it, too.

-I don't know what the hell that is. -Is that a symbol?

It's a -- like a backwards R?

Think about all the -- all the topsoil that we removed.

There was a lot that was up here, so...

-Oh. -...this has been here a long time.

[James] It's got to be marking something.

Why put it there.

These markings that we found here,

they're different than what we found back in the tunnels.

These are made with charcoal.

The ones in the back in the tunnels were ochre,

something that the Native Americans would have used.

These are more modern.

So with each artifact that we find down here,

we're getting closer to finding out or at least understanding

who was down here working.

What in the hell? [bleep].

It's opening up. [grunts]

-[Josh] It's opening up? -[James] Yeah, [bleep].

Look at that.

[grunts]

-Oh, that's a hole. -[Josh] Ooh, look at that.

[James] Can you stick your hand in there and just --

'Cause there's no way we're going to get the trowel

in that hole.

[Josh grunts] All right, I'll just bring up

some material? -[James] Yeah.

[grunting]

It goes way down there, James.

[grunts]

Well, I think maybe two foot,

a little less than two foot down.

[grunts]

[grunts]

[James] Whoa, whoa, whoa, whoa, whoa!

-[Josh] What? What do you got? -[James] Whoa, whoa, whoa!

You -- you just pulled out gold ingots.

[Josh panting]

You're full of it.

Holy [bleep]!

[tense music plays]

-[Josh] [bleep]. -[James] I'm [bleep] not.

-Look, check them. -[Josh panting]

-It's [bleep] gold. -Just plain as day.

-[laughs] -[bleep].

[James] Yeah!

[Josh] Holy [bleep].

Holy crap, dude.

-What the [bleep]. -[James] Whoa!

If -- I mean, if I pulled out those two

there's got to be more.

Give me -- give me a light.

[James] [bleep]. [laughs]

You did it!

[Josh] We just found gold back here.

Um, this is incredible.

They got left back. They got buried.

I don't know.

But they're -- they're back there.

We pulled them out of the ground, this is --

I mean, this is incredible.

This -- this is definitely the Keyhole Chamber.

Whoa, whoa, whoa! [bleep].

-[Josh] There's another one. -There's another one.

Look at that!

Whoo-ooh-ooh! [bleep].

[laughs]

Finding that gold is validation

for the entire team at Blind Frog Ranch.

Now that I've seen that,

it makes me think there's probably more.

I mean, if that's here, what else could be here?

I think we could be just on the tip of the iceberg.

[Josh] Holy crap.

[bleep]. [chuckles]

Next time on "Blind Frog Ranch."

[Chili] I think I see something.

I think it opens up. [grunts]

The Keyhole Chamber has been breached.

[Chili] No, back up, back up dude, I'm not messing with that.

And reveals a much bigger story.

[James] It's the start of a void right there.

Have you heard about a golden staircase

up here in the Uinta Basin?

An old friend...

-[Eric] Welcome back. -...makes a triumphant return.

And not being able to be here was kind of hard on me,

to be honest with you.

To confront the ghosts of a dig site...

Something strange going on under the property.

...that may still be haunting him.

The human body is gonna perceive that as something dangerous.
