Original subtitles

[Chad] The signal said that that beacon is right in this body of water.

[groans] Jesus.

[Chad] I didn't know they were all connected, which is crazy.

-We're this far away... -[man 1] Yeah. This could be leading right back.

Yeah, this could be one of the entrances.

And it might be deep.

Do you think you could dive that?

-Yeah. -[man 2] Let's do it.

[Chad] This is the risk we have to take to find this gold.

This could be another entrance to a whole underground cave system.

I'm showing 3,000 pounds.

Three thousand left?

And we might find that bitch today.

So right here, all along this wall,

-that's the area we gotta check. -[man 2] All right.

[man 1] Good luck, Chad.

-It's deeper than I thought. -He's way down there.

[man 2 speaking]

[Chad] Oh, my God!

[chuckles] Yeah, this is [bleep] wild.

[bleep] yeah!

[laughter]

Holy [bleep].

This is the cave.

[narrator] Northeast Utah is a place of mysteries.

Including legends of treasures

buried by long dead civilizations.

[man] Oh, wow, look at that.

This has to be hundreds of years back.

-[narrator] Unexplained phenomena... - [groaning]

What the hell is that?

[narrator] ...that defy human understanding.

I've never seen anything like that.

[narrator] All these mysteries meet at a crossroads.

A 160-acre property known as Blind Frog Ranch.

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

And each year, he's drilled closer to the truth...

Hell, yeah, he can go faster than that.

It's working!

[narrator] ...and long lost Aztec gold

he believes is buried deep beneath his ranch.

[man] It's freaking massive.

Could the Aztecs have discovered this?

[narrator] But the closer he gets...

[Chad] Whoo! Feel alive, boys!

Finally get to hold [bleep] gold in my hand.

[narrator] ...the more the land fights back.

[Charlie] What would eat the head off of it?

Weird [bleep] goes on around here.

-[man 1] It's blinking red. -[man 2] Poison gas.

Get out! Go! [bleep] Go!

[narrator] But Duane will move heaven

-and earth. -[man] Fire in the hole.

[all exclaiming]

[narrator] ...until he gets to the bottom of the mystery...

[Charlie] We've started this whole deal

and we're sure as hell gonna finish it.

[narrator] ...and solves what's lurking below.

[Eric] Holy [bleep]. There's something in there.

[Chad] Hell yeah!

[clamoring]

[narrator] ...at Blind Frog Ranch.

[Eric] So nice out here.

Yeah. Beautiful, isn't it? A lot less snow than last year.

For the last ten years, I've been helping my dad try to find this Aztec gold

that he believes is underneath the ranch

in the cave system.

[over radio] Perfect. Let's start digging over here.

We've come so freaking close to finding it,

and we've uncovered so many clues.

I know the gold is down there.

Look at that.

Look how far that goes.

But, man, it has not been easy.

[thunderclap]

It's like the land knows something.

[Duane] Oh... We might be sinking.

Like it's fighting us, trying to hold on to this treasure.

[man] Look at that son of a bitch.

[Chad] It's like the insides are gone.

But this year, nothing is going to stop us

from getting into those caverns

and finding that gold.

We know from imaging that we did last year,

that there's a huge chamber underground that's shaped like a keyhole.

We think it's man-made and it's massive.

Like a quarter mile long.

But we weren't able to find an entrance...

[man] No drilling now?

Time to call it. Shut it down.

[Chad] ...until I found that south cave.

Look at this.

There's a cave. There's an opening.

It's a narrow tunnel that goes underground

right towards the keyhole.

It opens up into a massive cave.

Like we go in this tight ass cave.

Went through it about a hundred foot,

and then it just opens up to this huge cavern, man.

And then, in the back of the cavern,

we found these, like, big hewned logs, like,

-man-made cut logs. -Oh, no kidding! Wow.

So if those were hand-cut,

-they could be hundreds of years old. -Yeah.

Oh, my God! Look it! Look it! Look it! Look it!

This is actually hewn. Somebody made this.

So far, we haven't found where the south cave

connects to the keyhole chamber.

But I'm sure that's the way in.

I just need some help finding that connecting tunnel.

-I've missed being out here. -Yeah.

We asked our geologist, Eric Drummond,

to come out to Blind Frog Ranch.

I want to take him to that south cave

and see if he can find a way into that keyhole chamber.

Nice. I want to see it. I want to get in there.

Yeah. You're gonna love it, man.

It's gonna blow your mind.

The past year, I've been working all over the world,

you know, looking at prospects here and there.

There's a lot of things out there to find.

But finding Aztec gold right here at Blind Frog Ranch,

that would be the find of a lifetime.

So I'm really excited to be back out here

and help these guys figure it out.

[narrator] According to lore,

when the Spanish army invaded the Aztec Empire in Mexico in 1519,

the Aztec emperor sent his fortune of gold northward

to hide it from Cortes.

The treasure is estimated to contain over 3,000 pounds of gold bars,

artifacts and jewelry

worth more than $3 billion today.

Scholars have long believed

that it was hidden underground

somewhere in northeast Utah.

[Duane] There they are.

There's two outlaws right there.

So we're just about getting ready to start digging here

on Blind Frog Ranch again.

We've been waiting all winter

to come back and find the gold.

We really think that Aztec gold

is stored in that keyhole chamber.

So getting in there, that's gonna be

the biggest step we'll do this year.

-[laughter] -Good to see you again.

[Eric] Good to be here.

I've been working with the guys for the last two years

trying to help them find gold.

We've got a lot of unfinished business here to figure out.

Charlie, we'll get that map.

-Let's show this to Eric. -[Charlie] Yeah.

Here's the keyhole-shaped cavern,

and that's why we dug here.

Bead Site right here and here's the south cave, right in here.

My money's on that south cave. That's our best option.

You know, that Bead Site's got artifacts.

It's got so much stuff going on.

[narrator] Last year, Duane and the crew discovered ancient artifacts

and smoke chimneys

at a location known as the Bead Site.

That's a great find. I'll go put that over with the others.

[narrator] These discoveries not only indicated human habitation,

but a possible entrance into the keyhole cavern.

And as we dig down, I think we'll find the dome.

Don't forget, the Bead Site is right over the tails of the keyhole chamber.

I mean, but we've already found the tunnel right here.

There's no telling how old it is, or who created it.

We're talking wood that's been placed in there

from somewhere that we have no idea about.

I think what we need to do is just split up then.

[narrator] The team has decided to explore

two different possible ways into the keyhole chamber.

The south cave,

which sits below the head of the keyhole chamber,

and the Bead Site,

which sits right above the tail side of the underground cavern.

All right, we get the south cave, y'all get the Bead Site.

It's a race to the treasure. Whoever loses, buys us beer.

All right. Deal.

All right. Well, we got two sides.

No bull [bleep] here, fellas.

If we can help y'all down on the other end, we will, and...

we won't need y'all's help.

[Chad] Yeah. This is the spot right here.

-[Eric] We're going up here? -[Chad] Yep.

[Eric] Wow.

-Right in there. Now I see it. -[Chad] Yeah, yeah.

[Eric] I mean, it's no wonder we've never found this before.

-[Chad] Yeah. -It's just so small. It's so well hidden.

So Chad and the crew brought me out here to see

where the south cave connects to the keyhole chamber.

So I'm gonna do a full assessment

for any entrances or tunnels they may have missed.

And I'm gonna grab some soil samples.

Oh. Certainly is small.

Right?

And look for signs of human activity,

which might point to a hidden tunnel.

These lines here,

-that's the bedding of the sandstone. -Right. Right.

But this right here, you see how

-it's all fractured up? -Uh-huh. Yeah.

-It's a zone of weakness, obviously. -Uh-huh.

And I also want to get a sample of those logs that Chad told me about.

All right.

-Let's do it. -Let's do it, man.

-[Eric] It's dark. -[Chad] Hold on. Let me get my light on.

[Eric] Get your light on, Chad.

-Here we go. -[Chad] Let's go. Let's get in there.

Let's check this out, man. I've been waiting to show you this [bleep].

[narrator] To get to the south cave,

Chad and Eric must crawl one after the other,

over 150 feet through a tight passageway

that is barely three feet in diameter.

Once at the south cave,

Eric will survey the area

for any potential tunnels to the keyhole cavern.

[grunts]

What the [bleep]?

It's tight, yeah?

I forgot how narrow this was.

[Eric] How much farther, Chad?

[Chad] Uh, we're about a quarter way there.

-[Eric] [bleep] -[Chad] It's worth it, I promise, man,

[grunting]

All right. It opens up a bit here, Eric.

-This is the fork in the cave. -[Eric] Okay.

[Chad] I want you to see this.

You can see where this goes in there.

And there's some rocks that are blocking it off.

[narrator] Seventy-five feet along the passageway to the south cave,

there's a fork that points to the west.

But it's unknown where it actually leads.

[Eric] That looks really tight.

We're not gonna be able to get in there.

[Chad] Yeah, let's keep moving.

It starts to widen up a little bit further over here.

-Here it is, man. We're finally here. -[Eric grunts]

[Chad laughs]

[grunting and panting]

[Chad laughs]

Look at this [bleep], man.

[Eric] Oh, ho, ho, my!

I can see it already.

-Look at this! -[Chad laughs]

Wow!

Holy cow!

-This is huge. -[Chad] Isn't this wild?

[Eric] Oh, my God!

This place is amazing.

[Chad] Just wait till you see the rest of it.

[narrator] Coming up on Blind Frog Ranch...

-Holy [bleep]! Something moved in there. -[Chad] What?

Light, light, light. Right there.

Damn, look how big that son of a bitch is.

That's a [bleep] wolf.

Charlie, you got your gun?

[Eric] Oh, ho, ho, my! This is huge!

[Chad] Isn't this wild?

Look at this.

And it goes way back this way, too.

[Eric] Chad, look at these stalagmites.

[Chad] Wow!

Forming from the ground water percolating down,

freezing.

Oh, look at that.

-That's amazing. -[Eric chuckles] Yeah.

This place is amazing.

Wow!

[narrator] Ground water seeping into the cave from above

has formed stalagmites.

As they form, the ice captures oxygen inside,

which fluoresces when ultraviolet light passes through,

making the ice appear to glow.

But the source of the water is unclear.

The dry rock formation above the cave

should be shedding water away from the caverns.

Instead, a steady supply of ice cold water

is slowly seeping into the cavern from parts unknown.

[Chad] That is so [bleep]...

[Eric] It's beautiful.

Most caves have a year-round temperature

of about 55-60 degrees Fahrenheit.

And that's because they're insulated from the surrounding weather.

And this cave has stalagmites that are frozen.

And so that, to me, indicates

that there is both water and cold air coming in.

So we have some openings somewhere.

It could be a lead.

Over time, the water seeps in and carves out these caverns.

But honestly, it's still carving as it settles.

There may even be more voids below us.

[Chad] Wow.

These are the logs.

-Here they are right here. -Wow.

The logs are huge.

Yeah. It's like, how did they get in here?

Absolutely no way they could have gotten in through that opening.

[Chad] Yeah. They had to get in some other way, though.

Let's get a sample of these.

We might be able to carbon date these.

We can see if it's similar wood as the box in the pond.

[Eric] Yeah.

[narrator] Four years ago, Chad discovered a wooden box

in a water-filled cavern on the ranch.

The box was made with 500-year-old Chihuahua pine

which is consistent with being from the Aztec empire.

If the timbers in the south cave

are the same species and age,

it could be further evidence

that the Aztecs were in Utah and on Blind Frog Ranch.

[Eric] Bag it, tag it, send it off to the lab.

That'll work.

[narrator] The team will analyze the wood samples

using radiocarbon dating to determine the age

and dendrochemistry analysis to determine the tree species.

[Eric] I'm wondering if the Aztecs were in here

using this as shoring.

But I just... Why did they stop?

[exhales]

This should be enough.

We'll get some answers here, hopefully.

Let's keep going.

[Chad] Back here was the hollow spot that

when you bang on it, it's like a false floor right here.

I'll show you.

-[Chad] Did you hear that? -Yeah, it does sound hollow.

Maybe that's how they got those logs in here.

Maybe someone purposely buried it

so we can't get in there.

And look at that, too.

-[Eric] Yeah, that goes-- -A ways in there.

-I think that tunnel fork we saw back in there... -Oh, at the cave. Yeah.

And this area here are both good candidates to dig out.

Yeah, I think so.

My best guess at this point is that

either the tunnel fork or the hollow sounding floor

could lead us to that connecting tunnel.

Next, we'll do a scan with a magnetometer

to pinpoint where to start excavating.

We'll pack her up here and get out.

[Duane] Bob, how's it going?

-[Bob] How have you been? -Good, good.

Glad to see you again.

Well, it's time to figure this deal out here.

[narrator] Duane and Charlie have invited scientist Bob Morton

to help them examine the Bead Site,

an area that sits above the tail end of the keyhole.

Over the years, Duane and his team have discovered

many indigenous artifacts at the Bead Site.

They also noticed what appeared to be smoke vents

on the side of the rock.

Even over there, like, vents.

These little holes where smoke goes up.

[narrator] All these clues lead Duane to believe

the area may hold an entrance to the underground chamber.

Ever since we've been here, we've always thought that

those smoke marks were vent holes from

humans somewhere down below us.

[narrator] Duane has asked Bob to test the material on the walls.

If it is soot from human activity,

then it would indicate that people were living

somewhere under the Bead Site rock formation.

Perhaps within the keyhole chamber.

Yeah, this soot is nowhere else to be found on this property.

-Really? -Mmm-hmm.

I'm Dr. Bob Morton. I'm a professional analytical chemist.

What's interesting about coming back here,

is you find things that are extraordinary

and you scratch your head.

And you're trying to figure out

what in the heck is going on, and how are they related?

We'll take a sample

and we'll analyze it and find out what it is.

So your test should be able to

tell us maybe an age factor of this soot?

If there's carbon there.

Whether we see evidence of burnt plant material.

[narrator] When logs are burned,

they leave behind elemental carbon

in the form of ash, soot and charcoal.

If the black material turns out to contain carbon,

that means some settlement, possibly Aztec,

was stoking fires deep below the Bead Site.

And the material residue would also allow Bob

to determine the age of the soot through carbon dating.

[Charlie] So what kind of hi-tech doodad have you got for us today, Bob?

Razor blade, plastic cup, and let's not forget the lid.

That's all you need to take your specimen.

And right now, it's this black layer right in here

that we want to get

off the rock and collected.

[Charlie] Bob, we definitely want to get samples out of this soil over here too.

[Bob] Okay.

[Charlie] The difference in the soil over here, you can see it's soot.

The deeper I dug here, the darker it got.

[Bob] This is really an interesting area.

[Charlie] There's beads everywhere here, Bob.

-[Bob] Oh, really? -[Charlie] Mmm-hmm.

[Bob] Let's see if we can pick up a few.

There's a turquoise one right here.

Each color represents a different formula

that back in ancient times, like 500 years ago,

those were trade secrets.

Here's a red one.

And that color is indicative of glass made with gold.

-Really? -[Bob] Uh-huh.

Another bead.

Uh, there's another bead.

We damn sure call it the Bead Site for a reason, Bob.

[Bob] There's a lot of information here.

I'm gonna go back to the lab,

and we're going to look at these materials

so we understand where they came from and what they are.

There's about to be something interesting that you're going to find.

[James] This is amazing.

Over here used to be Montezuma's palace.

[narrator] Over 1,500 miles away in Mexico City,

ancient civilizations expert James Keenan

has been sent by Duane to search for clues

about the ancient artifacts they've been finding on the ranch.

So I'm headed to meet a local historian

who's very knowledgeable in the Aztec culture.

[narrator] Last year...

We sure as hell got the right guy.

[narrator] ...James joined Duane's team...

We have history and knowledge lost right below our feet.

[narrator] ...and helped to push Duane's investigation forward.

What do you need to protect a vault?

Freakin' geological castle.

[narrator] ...which ultimately led them to the discovery of gold.

Look at this. Finally get to hold [bleep] gold in my hand.

[narrator] And today, he's meeting with local historian Julio

to try to understand how gold made its way

from the Aztec capital city to Utah.

-[James speaking Spanish] -[Julio] Oh!

-James! [speaking Spanish] -[in English] How you doing, Julio?

[speaking Spanish, then English] Doing great.

[James] We're here at Templo Mayor,

which was the main temple of what was formerly

the Aztec capital, Tenochtitlan,

which is now Mexico City.

-[Julio] Well, let's take a look inside. -I'll follow you.

Julio's a colleague of mine that knows a ton about Tenochtitlan

and the artifacts that were discovered here.

I've been corresponding with Julio

and sharing some of our findings at the ranch.

Look at that.

And he believes that the Aztec gold

could have made its way from Tenochtitlan up to Utah.

Quite possibly below Blind Frog Ranch.

So here it is.

That's what you were looking for.

This is it. This is the few gold that's left.

All that was used by the indigenous people.

Only the high priests, only the leaders

important people were able to wear

these kind of artifacts, like you see these.

Here we see the bar, that was done by the Spaniards.

So that they could run away with it.

They could get it out of the city.

[narrator] In 1519,

when the Spanish, led by Hernan Cortes,

invaded the Aztec Empire in Mexico,

they attempted to steal four tons of Aztec treasure

by melting the gold into bars

and hiding it under their armor.

They were thwarted by the Aztec emperor.

And historians believe the Aztecs

then sent the treasure north to hide it

somewhere in Utah.

[Julio] So as far as the original gold Aztec artifacts,

not much was left in Tenochtitlan,

We know there's a lot more,

but we're not exactly sure where it is.

[James] And if the Aztecs recovered it

and fled north through Utah, I mean,

the rest of it could be under Blind Frog Ranch.

This is what we're looking for.

[Chad] All right, here we go.

[panting and grunting] All right.

We're almost there.

Eric, you wanna check out that tunnel fork on the way back?

[Eric grunts] Yeah.

[Eric] Are we there?

[Chad] Yeah. Here's the fork right here.

It's tight, isn't it?

[Eric] Yeah.

I just want to see if it could be an entrance to the keyhole cavern.

I got the endoscope here.

[Chad] Perfect. Yeah. Bring it up here. Can I grab it?

[Eric] Yeah. You have to get that.

-I got it. -Got it?

-I think. -All right.

Got it, man.

[Chad] When I first crawled in there

and saw this side tunnel, I thought

that's way too tight to fit through.

But everything is on the table now.

If we could somehow widen that entrance,

this could be our ticket into the keyhole cavern.

It looks like a partial collapse in there, doesn't it?

Yeah, it does.

Either a cave in

or someone tried to do it purposely to hide it.

[Eric] Let's send that endoscope in there.

All right. Perfect.

[Eric] And let's see what we can see.

Just feed it through.

And I'm seeing it right here.

It's looking good.

[Chad] I'm gonna climb in to get a little further in,

straighten this endoscope out.

[Chad grunts]

[Eric] Yeah, a little bit more, brother.

[Chad grunting and panting]

[Eric] How's it going, Chad?

How far you got it down in?

-I'd say ten foot right now. -Okay.

I'm trying to feed it, but it's flopping around.

[Eric] There we go.

All right. You see anything, Eric?

[Eric] It kind of looks like it opens up in there.

Can you get it in any more?

[Chad] Okay.

I'm trying to feed--

Holy [bleep], Chad! Chad, something moved in there.

[Chad] Rocks moving? What?

[Eric] No, there's an animal in there.

-[Chad] In the back? -Yes!

[bleep]

[Chad] Let me see that camera.

-There you go. -So I can see in there.

I don't see anything.

What'd it look like?

Just a blur, but it was something big.

There was something moving around?

It was a blur, but I have no idea what it is.

[Chad] Let me rewind this.

Holy [bleep].

[bleep]

[Chad] Is that a mountain lion?

[Eric] Mountain lion or a coyote? I don't know.

You know, the bigger question is,

how the hell did it get in there?

[Chad] If there's an animal back there,

the tunnel must widen and connect somewhere.

Yeah, yeah.

[Chad] [bleep], man.

It's like, weird [bleep].

[Eric] I don't know what it was,

-but let's push on and get out of here. -Let's go.

[Eric] We're gonna have to come back to get a better look at that tunnel.

[Chad grunting]

Come on, Chad.

[Chad] Yeah, we got two more turns,

and we'll be out.

All right, we're at the end right here.

[Chad] Yeah.

All right,

All right, man. [sighs]

-Shh! -[rumbling]

Out, Chad. Out!

[Chad] What the hell is that?

I don't know. Just keep going before we get trapped.

[Chad] I'm going! I'm going!

Go! Go! Go!

[both grunting]

[bleep]

[Chad] Eric!

[Eric] Chad! Chad!

Argh! [bleep]

[bleep]

[Eric] Damn it! Chad!

[bleep]

[Chad] Need a little help here.

[bleep] Damn!

[Eric] Let's go, Chad!

[Chad grunting]

[Chad] What the [bleep] happened?

-It was like a rumble that started shaking. -[Eric] Yeah. What is it?

Was it like a [bleep] earthquake or something?

I don't know.

[Eric] To me, it sounded like a big collapse

somewhere deep in that system.

The important thing is you got out of there. Man!

Ah, [bleep].

We gotta go in there real carefully.

Phew!

Hoo!

We'd better [bleep] tell my dad and Charlie.

Hey, Bead Side, Duane and Charlie.

Y'all hear me?

[radio static]

Duane, Charlie, you copy?

There was like a rumble over here. Did you hear that?

What was that?

Yeah. We were inside the cave when we heard that.

Scrambled out. We're good.

[Chad] Copy that.

-[James] I'll follow you. -[Julio] Vamos.

[narrator] Back in Mexico City, local historian Julio

has taken James to the archives

to examine ancient maps for clues

as to the path the Aztecs might have taken north

with their gold while fleeing the Spanish.

Mexico City is basically here, and they kept going up north.

[James] Through the desert.

[Julio] They had to take their treasures with them.

And it was very difficult for them

to go just up straight north

because they couldn't go towards the Gulf of Mexico

because it's jungle there.

So they would have headed a bit west.

New Mexico, Arizona, and then they ended up in that region of Utah.

Years later,

Spanish explorers came to the same area of northern Utah,

and they made a map of something incredible they discovered.

And this is that map.

So here in this map,

we can see the north of the region of Utah.

[James] What does it say here?

[Julio] It says...

[reading in Spanish]

[in English] So, from the shores of this lagoon,

the Indians of Mexico went out to found their empire.

This is the place of origin

in that region of Utah.

What Julio translated from this map

is quite possibly the most incredible findings

I've ever heard in all of my Aztec research.

It basically says

that the Aztec people originated in Utah.

For years, the historians were wondering,

why would the Aztecs bring their gold to Utah?

Well, it was because they were bringing it to their ancestral homeland.

Which translates as "the place of the seven caves."

[narrator] According to their legends,

the Aztecs' ancestors

originated in a place called Chicomoztoc

or the Place of the Seven Caves.

Though the exact location was lost long ago,

this Spanish map places Chicomoztoc in Utah.

[Julio] This is a drawing of Chicomoztoc.

[James] Holy [bleep].

[Julio] So here we can see the seven caves,

the mountain,

and we see that there's surge plains on top

You even see these people using a coyote skin,

and that's totally from the north.

[narrator] Julio has shown James

an Aztec illustration of Chicomoztoc,

an underground civilization that was believed to house

the seven tribes that formed the Aztec people,

a location they left in the 13th century

to form their empire in central Mexico.

For James, this is the first time

he's seeing this depiction together with the Spanish map

that states that Chicomoztoc is in Utah.

This drawing is incredible. There's all these details.

But what stuck out to me the most

is that there's these seven caves.

Utah history is filled with rumors

of a Mormon gold mine with seven entrances

known as the Lost Rhoads Mine.

Last year, we were tracking clues to the Rhoads Mine

through seven caves.

[Chad] 100% there's a cave.

This is definitely a mine shaft.

[James] I think you're right on the money.

We have a keyhole cavern system

underneath Blind Frog Ranch.

And it's 90% the same thing.

I think when you put it all together,

it just helps solidify

how important all this evidence is.

Not only could Blind Frog Ranch be sitting on top of the gold,

Blind Frog Ranch could be sitting on top

of the lost civilization of Chicomoztoc.

I have got to show this to Duane.

He needs to hear it, see it.

This is major.

[Duane] Come on in, fellas.

Let's get Bob up on the...

on the computer.

[narrator] Duane has called the crew back for a meeting.

[Chad] Bob, how's it going?

Hey, Chad. Good to see you.

[narrator] Bob Morton has completed

his X-ray fluorescence, or XRF, analysis

of the vents at the Bead Site.

Now, he's ready to share his findings.

[Bob] ...what you thought was chimney smoke.

We analyzed by X-ray fluorescent spectrometry.

And I have some answers for you.

Okay. All right.

[Bob] Black plumes from the rock around the Bead Site...

[scraping]

What we found was...

it comes back as

charcoal and charred plant material.

[Chad] I'm glad you said that. Damn.

[Duane] Hell, yeah.

[Bob] This verifies what you were thinking.

[narrator] Bob's analysis not only indicated

the black soot came from man-made fires,

but the carbon dating of the material

puts it at roughly 500 years old,

the same time period the Spanish attacked Tenochtitlan,

sending the Aztecs north with their gold.

Well, Bob, that's good information.

Appreciate all that.

Anytime.

Bob just gave us a hell of a result.

This tells us that someone was living down below the Bead Site

at the time of the Aztecs.

The next step is to dig that Bead Site up.

-Thanks, Bob. See you. -Bye.

[creature growling]

-[Chad] What is that? -[Charlie] Like an old bear.

Charlie. Light, light, light.

Right over there.

I heard something right over there.

Right here.

[Charlie] I don't see anything.

[Chad] There. Holy [bleep]. I see it moving.

That thing's [bleep] huge.

[Charlie] Damn! Look how big that son of a bitch is!

-[Chad] You see its eyes? -[Charlie] See its eyes?

[Chad] I got night vision. Hold on.

Shut that off. Hold on.

Look at that.

That's a [bleep] wolf.

[Charlie] There ain't no wolves within 300-400 miles from here.

[Chad] That's a [bleep] wolf right there.

[Charlie] I don't see it.

[Chad] Right there.

You got your gun?

What the [bleep].

What the [bleep].

He's gone. I don't see him anymore.

I just saw him right here and he's gone.

He just [bleep] disappeared, man.

What the [bleep].

-[wolf howling in distance] -Blind Frog Ranch. Something's out there.

[narrator] Blind Frog Ranch is located 30 miles away

from the notorious Skinwalker Ranch

deep in the Uinta Basin,

a hotbed for paranormal activity.

Native Americans and early settlers

spoke of unnatural creatures, unexplained disappearances,

and a strange rumbling noise in the mountains...

[rumbling]

...that foretold death and disaster.

[thunderclap]

Reports persist of UFOs...

[man] That one right there, look at that.

[narrator] ...crop circles,

cattle mutilations...

[Charlie] This sumbuck was ripped open from the belly.

-[narrator] ...and shape-shifting creatures. - [creature howling]

[Chad] We've seen some weird [bleep] here

and faced danger along the way.

-[man 1] Poison gas. -[man 2] Let's get out. Go!

-Go! -[Chad] But we're not stopping.

In fact, we're just getting started.

-I'm back. Thank you. -[Charlie] Welcome back, James.

I got a lot of stuff to show you all.

[Duane] Yeah. Yeah.

[narrator] James has returned from his trip to Mexico City,

eager to share his findings with Duane and the team.

What have you got going on here, James?

So if we talk about the Aztec history,

I've always told you all that I believe

that they originated from here.

But down in Mexico,

I found proof.

This map was made in the early 1800s.

And what we are looking at

is this area from what the Spaniards had seen,

and what they have been through on their expeditions.

Well, you know what this is, gentlemen?

This is the Great Salt Lake.

Do you know what these are?

Uinta Mountains.

-That's where we're at, right in here. -Yes.

But this line is what caught my attention.

It translates, "From the shores of this lake,

the Aztecs left to found their empire."

[Chad] So the Aztecs were from here.

From Utah.

Exactly.

[laughs] [bleep]

That's great.

That's amazing.

[James] The Aztec oral history states

they came from what's known as Chicomoztoc.

It translates roughly into "the seven caves."

[Charlie] Oh, wow.

[Chad] Could the Lost Rhoads Mine be a part of these caves?

We're talking about seven caves. I mean, it's possible.

[Chad] Hell, yeah.

[narrator] According to local legend,

one of the seven entrances to the Lost Rhoads Mine

was revealed to Thomas Rhoads, a Mormon pioneer

by Chief Wakara of the Timpanogos Nation.

The Timpanogos were known as the keepers of the Aztec caverns,

leading some scholars to believe

that the Lost Rhoads Mine

could be connected to the gold from the Aztec empire.

Caleb Rhoads' clues could have been based on the legend of Chicomoztoc.

[Duane] It did have seven entrances.

-[James] That's it. Yeah. -Wow.

[James] But here's what's even more interesting.

Down in Mexico, Julio showed me this painting

from a 450-year-old codex.

This is the illustration of the Aztec homeland, Chicomoztoc.

Keyhole cave from last year.

Seven caves Chicomoztoc.

They match up.

-It looks like the same thing. -[Chad laughs] Same thing.

Holy [bleep].

You know, this is big, James.

[bleep] yeah.

[James] The other thing, too,

is Chicomoztoc was supposed to be

below this bent or curved hill or mountain.

But I think that this feature

may actually be above the energy zone

where we have those rocks that are somewhat bent.

[Duane] No way.

[James] And the legend also says

Chicomoztoc was near a river.

Well, that's likely Crow Creek.

So this keyhole could be the home of the Aztecs.

[James] Correct.

This could mean the Aztecs didn't just originate in Utah,

they originated here.

[Duane] This is major.

[Chad] Wow!

[laughs]

And what safer place to take treasure than here?

A place they already knew about

because it was their ancient homeland.

-It's all lining up. -[Chad] Yeah.

[Duane] This is bigger than we have ever imagined.

Not only are we closer than ever

to finding that treasure,

we might be sitting on the birth site

of a whole civilization.

[Chad] We're close. We're close, boys.

We gotta get on this.

It's gonna be a big year.

Let's get to work, fellas. Let's go.

[narrator] This season

on the Mystery at Blind Frog Ranch...

What are we waiting for?

[narrator] New leads have the Ollingers bringing in a hired gun.

-Fellas, this is Josh. -[Bob] How you doin'?

[narrator] Fresh eyes bring fresh finds.

-[man 1] That's dinosaur bone. -[man 2] This is working.

We need to chase it then.

[urging horse]

[narrator] But the land doesn't give up its secrets without a fight...

[Duane] Watch out!

[bleep]

[narrator] ...and dangers above ground...

[Chad] Oh, man! They keep coming!

One rock comes down, you're dead.

[narrator] ...and below...

[Chad] It's opening up.

Everyone out! Everyone out! Get out! Out! Out! Out! [bleep]

[narrator] ...threaten to derail

-the entire operation. - [bleep] bro.

Further we get into this deal,

the more dangerous it's getting.

That's a long ways down.

[narrator] With the ancient Aztec treasure in reach...

That gold is cursed.

[narrator] ...Duane and his team are willing to dig deep...

-[man] It's gonna drain. -[motor switching on]

[Charlie] It's pumping a lot!

Hell, yeah.

[narrator] ...push hard...

[Charlie] Let her have it! Get it, Duane!

[narrator] ...and put it all on the line.

[Eric] There's a lot of predator/prey going on here.

[Charlie] Hey!

I just hope we're not the prey.

Hold on! All stop!

You got a skull? Like a human skull?

[narrator] ...to finally solve...

This was put here.

We got gold, boys!

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

Now you're talking.
