‐ Narrator: ..."Lost Gold of World War II"...

‐ I found this inside of the tunnel

in an area where there was a part of a collapse.

‐ This was without a doubt an American knife.

‐ Holy... ‐ Wow.

And that could mean there's another way

into our waterfall.

‐ There's something right here.

‐ I really want to see what's in the bottom.

It's time to get an excavator up here.

Keep it coming.

‐ John Casey and Rick Hurt are back in the Philippines

with a new team,

continuing their search for Yamashita's gold.

‐ We're gonna find a way to get to this treasure.

‐ Like many others,

John believes

Japanese general Tomoyuki Yamashita

took billions of dollars in treasure

looted by Japan during World War II

and buried it in the Philippines,

including somewhere in this mountain.

Following a series of mysterious symbols

they believe were left by Yamashita,

the team is investigating three sites‐‐

a waterfall...

‐ This waterfall's hiding something.

‐ ...a crater known as Breach 6...

‐ I've never seen anything like this.

‐ ...and a camouflaged tunnel they uncovered last year.

‐ We are in the mountain, boys.

‐ Can they finally discover the...

On a remote mountain in the Philippines,

a team of miners led by Rick Hurt

continue excavating at Breach 6.

‐ Ultimately, we're trying to get

to the treasure.

Hopefully, this is the access point.

‐ A recent nuclear magnetic resonance,

or NMR scan,

revealed that Breach 6 is in the middle

of a line of underground metal deposits

which the team believes could be treasure

left in a tunnel by the Japanese.

I've not dug in anything

that's looked like this before.

‐ After digging through 8 feet of soft clay,

the miners make an unexpected discovery.

‐ Really could be a concrete cap.

Once you find concrete,

then you know

somebody's been there before you have.

Maybe the Japanese were using concrete

as protection or an indicator

when they were dealing with these treasures.

‐ Based on a study of tapes

provided by a secret informant,

Rick thinks the concrete could be covering a tunnel.

The tapes were made in the 1970s and '80s

by an American mining expert named Robert Curtis,

who worked for Ferdinand Marcos

to recover Yamashita's gold.

‐ I've been listening to these Bob Curtis tapes.

In the shafts Bob Curtis was digging,

they also found concrete.

‐ Right now I'm the most excited I've been.

I think we're the closest

to finding another way into the mountain.

‐ Wow, that stuff's looking soft.

It's really, really soft.

We hit a spot under there where it was possible concrete.

We've jackhammered through that,

and we're back into soft material now.

‐ Brent, you're out of that concrete?

‐ Yeah, looks like soft clay, fine material.

‐ I was hoping for the top of a tunnel.

‐ We're about as far as we can go

without putting some steel in, man.

‐ Yeah, you're getting down there a bit now.

We were really hoping,

when we broke through this concrete,

it was gonna uncover a void space or a tunnel.

All's we found was more dirt.

‐ In order to continue digging safely,

the team must build a steel frame

to keep the shaft from collapsing.

This is their best chance

to find what is buried beneath Breach 6.

Rick: We really don't have an idea

of how deep we're going,

so we'll need to get the steel in there

and get things shored up good

so that, we're not gonna have a cave‐in

pin anybody in.

‐ Up at the waterfall site,

John's been looking for a way to access

what he thinks is a treasure chamber

300 feet below.

Unfortunately,

he hasn't been able to figure out a way in.

‐ It's one thing to know where something is.

Doesn't mean you can always get it out.

‐ The ground below the waterfall

is diorite, one of the hardest rocks on Earth.

The type of equipment needed to excavate diorite is huge

and impossible to haul up the steep mountain terrain.

‐ Even if I could bring it in,

the whole water supply for the town below

comes from our waterfall.

We're not gonna be screwing with the town's water supply.

‐ Days ago,

Rick found a possible solution

on the Robert Curtis tapes.

‐ They found a tunnel system connected to the waterfall.

‐ And that could mean there's another way into our waterfall.

‐ 20 years ago,

Rick advised a mysterious Philippine treasure seeker

known as Colonel Coriaso,

who operated on this mountain.

‐ Coriaso always thought

the treasure was under the waterfall.

But he never had us dig there.

I mean, he had us down over on the side of the hill,

quite a ways over to one side.

That's where he wanted to dig.

‐ Based on Rick's memory and the tapes,

the tech team scanned the area

and found a new place to dig.

‐ Colin: There's some type of metal anomaly

in‐‐in this area.

‐ John: I really want to see what's in the bottom here.

‐ Determined to find a way into the waterfall...

John sends in the second excavator

with Rob and Michele.

‐ Michele: I didn't think we'd ever get here.

I'm excited.

‐ After a tough journey through harsh terrain,

the team finally reaches their destination.

‐ Good. ‐ I'm stoked, man.

We're, like, 10 feet away.

Keep going till you can't.

‐ John: I want to get down to this metal target.

It certainly could be a tunnel

leading possibly right to the waterfall.

It's really speculation at this point

until we find what we're looking for.

‐ Go ahead and rotate till your boom is almost

about at that tree next to you.

Hey, that's about as far as you're gonna go.

We're here. That's it. That's all we need.

‐ Whoo. Whoo‐hoo! ‐ Way to go, Michele.

‐ We made it.

‐ John: It's just a huge gamble right now.

We don't know exactly what's down there.

I'm hoping that could be an entrance into the tunnel.

We're just not sure.

‐ While the team goes all in on John's theory,

miners Levi and Geo continue exploring

the mysterious tunnel the team discovered last year.

‐ We got to rip some more timber sets out.

We're just gonna keep getting in there farther and farther.

Maybe into a compartment or something

that might hold treasure.

‐ Though they believe

this tunnel was built by the Japanese

during World War II,

the discovery of a knife

manufactured well after that war

has them questioning who else has been here.

‐ It's easy to say this knife has been down here

for 40 or 50 years,

and that puts it 1970s, 1980s, maybe.

‐ If it was '70s or '80s, the chances are

that there have been treasure hunters in here.

Did they find something?

Did they beat us to the treasure?

‐ In search of answers...

‐ Those posts were in there pretty good.

‐ ...they make their way deeper into the tunnel.

‐ What the heck.

Hey, Levi, look at this.

‐ What do you got there?

‐ Looks like an old plate or something.

Looks ceramic, doesn't it?

‐ I'm not sure.

Do you smell that?

‐ What is that?

‐ I'm getting an idea what this is.

Being in the military and being in the mines,

we do a lot of explosives.

A lot of different explosives that you use under ground

have a distinct smell to them.

As soon as I was able to get a whiff of this,

I knew it could possibly be nitroglycerine.

What's scary about this whole thing,

whether it be a Japanese booby trap of some sort

or whether it be dynamite

that was left inside of this tunnel,

the thing about that old dynamite like that,

it has nitroglycerine in it. ‐ Yeah.

‐ That nitro will start sweating,

and it is highly, highly volatile.

You drop a rock on it, it'll blow up.

‐ Created in 1847,

nitroglycerine was widely used in ordnance

during World War II.

The primary ingredient is glycerol,

which is found in animal fats.

During the war,

the American Fat Salvage Committee

rallied housewives to donate their leftover cooking fats

to be processed into nitroglycerine.

According to the campaign,

1 pound of fat was enough

to create a pound of explosives.

Nitroglycerine is highly unstable

and susceptible to accidental detonation.

An obvious risk to anyone excavating the tunnel.

‐ You know, This is getting to be

a pretty scary business we're in here.

‐ Well, that's just it.

We don't want more to worry about

than just getting hit with rocks at this point.

Until we know it's safe to go back to work,

no one's going in there.

At this point, the tunnel is shut down.

‐ After finding a suspicious substance

in the tunnel,

the mining teams calls in an explosives expert.

‐ Levi. Nice to meet you. ‐ Nice to meet you.

My name's Chad Higginbotham.

I am a weapons and explosives expert.

I was on this mountain last year

and defused some booby traps that we found.

Hold, hold, hold.

Could have hurt somebody. Give me that.

It's the top of a potato masher grenade.

Every time that I come back here,

I'm always finding something new and exciting

about this mountain,

like this tunnel that they found.

‐ This is the first thing we found.

‐ ‐ And then inside of this

was‐‐was a substance which we don't know what it is.

‐ Yeah, it smells a lot like cordite.

‐ Invented in 1889 by British chemists,

cordite is an explosive

made from nitroglycerine and petroleum jelly.

It was used in ballistics

for rifles and anti‐aircraft guns

during World War II

and was even part of the detonation system

for Little Boy,

the atomic bomb dropped on Hiroshima.

‐ A lot of these components

are 75 to 83 years old.

They're degraded,

and sometimes it's really hard to defuse them,

and I don't know how long

you guys have been working in here and that,

but I'd like to take a look,

look at the walls and things

'cause this thing could be booby trapped

from the front to back

and y'all have just been lucky so far.

‐ Yep. ‐ Who's going?

‐ Chad: Levi and I are gonna go in.

He's gonna show me where they found the device.

I'm gonna take a look at it, see if it's safe,

if I need to back them off.

As I start into the tunnel,

I'm looking for any other booby traps

that may be around,

trip wires.

‐ To demoralize the Allied forces,

the Japanese military regularly deployed

explosive booby traps.

Roughly 30 tons of World War II explosives

are still found annually,

including throughout the Philippines,

so Chad and Levi must exercise extreme caution

as they approach.

‐ Going into a tunnel like this with an unknown device,

yeah, there's a little pucker factor there,

but to me, finding a device

is like finding a bicycle on Christmas morning

under the tree for a kid.

I love this stuff.

‐ Okay, it's right there on the ground

and straight across from that bar.

‐ Yeah, if you'll step back a little bit,

let me take a look at it

and see if there's anything else around.

I'm gonna dig around a little bit.

If I'm gonna remove a mine

or anything from this time period,

I take my time.

I'm very careful with what I do,

my movements,

how much pressure I put on the sides

because it can be very unstable.

‐ What do you see in there, man?

‐ I think it could be a Japanese mine,

so I got a high‐tech piece of equipment here

to test for that‐‐

two really sharp sticks.

‐ What are you gonna do with those?

‐ Probe under it

and see if I can feel another mine.

There could be others in there.

Most of the time, they wouldn't just set one.

This is like worm fishing.

‐ The big thing that's spooky is,

you get into old explosives,

it's not like the explosives we use nowadays

that are super stable.

Unless you have a really hard concussion,

it won't set them off.

This kind of stuff here,

the most minute bit of impact

can set this stuff off.

That's the scary thing about the whole situation.

‐ Now, there's nothing under it.

‐ So you see a detonator or anything?

‐ No. The plunger seems to be gone.

All right, Levi, if you want to come on up.

You can see what I'm looking at here.

I'm gonna pull the rest of this mine out of here.

We're gonna take it outside

so I can look at it in the‐‐in the daylight.

‐ Yeah.

‐ You brought it out?

‐ This is what you were finding pieces of.

‐ Basically, with the pieces that I have,

you can get a pretty good idea of how big this thing was.

‐ ‐

‐ This would be the top,

and the plunger would be right here in the center.

I think it's a Japanese A3 land mine.

It's made out of terra cotta.

It's just like the terra cotta pavers

people use for their walkways

and their patios and things like that.

‐ So why were they using terra cotta?

‐ They were building ships and tanks

and guns and everything else,

and they were running out of metal,

so they came up with this.

‐ As the Allies advanced in the Pacific theater,

shipments of steel from mainland Japan

were either destroyed by U. S. forces

or used to fortify coastal defenses

and command posts.

Inland soldiers were forced

to improvise with other materials,

like the terra cotta.

‐ If this thing would have been live

and you'd have reached down and stepped on it,

pulled it up or anything,

it could have been a really bad day for you guys.

The kicker is,

can't find it with a metal detector.

And you can walk past it two or three times

and not realize what it is,

especially with the timbers and things that are in there.

I'm calling in a K9 unit

to search this tunnel for any other devices.

If it's in there, they'll find them.

‐ Meanwhile, at Breach 6,

Brent and Farrell continue constructing their steel frame.

‐ This is hard work, man.

We better find something at the bottom of this hole.

‐ So this is a post.

We're gonna use this

to box in the whole top of this,

and that'll keep anybody from falling in the hole,

and it'll also keep that up there

from coming down on top of us.

‐ Once the site is secure,

the team can keep digging their way

toward the metal deposits.

‐ This is the easy part, actually.

The digging's the hard part.

So the steel's nice, actually.

It gives you a little break from digging.

‐ Eager to see their progress,

Rick stops by.

‐ Not half bad.

‐ You, ready to go?

If this is concrete,

I'm hoping that we're real close to something.

We don't know what, but we're close to something.

‐ Want to tell Rick to pull that up?

‐ Yep.

‐ We need to get things shored up good

so that we're not gonna have a cave‐in pin anybody in.

I am so excited to find out what we've got down there.

‐ Another one up.

‐ Yo, guys.

You guys might want to come look at this.

‐ What do you got there, dude?

‐ It's some dark, dark stuff.

‐ What the heck is that?

‐ That looks like a burnt piece of wood.

‐ That's charcoal.

You can see the wood grain in it and everything else.

That is charcoal.

‐ It looks like there's a lot of it down here.

‐ Look at that.

‐ It's a couple inches thick for sure.

‐ I wasn't expecting charcoal.

‐ I mean, it's a pretty distinct layer.

It runs all the way across.

‐ That isn't natural.

That's got to be put in there by somebody.

Well, we've gotten down below what we thought was concrete,

and we've run into a layer of charcoal.

It's large pieces of charcoal,

and you can actually see the wood grain in them.

That's really unusual.

‐ Wow. There's a lot of it.

‐ That is definitely burnt wood.

But it does make me more confident

that the hard layer that we ran into a few feet up

was probably placed there on purpose as well.

Somebody put this here.

Somebody put this here for a reason.

I don't know what that reason is,

but I think we can find out

with a little more investigation.

‐ After finding a second layer

of unusual material in Breach 6,

Rick turns to the Robert Curtis tapes

to see if they can shed any light

on these bizarre discoveries.

‐ We need to take another look

at these tapes we've got from Bob Curtis.

I mean, he talks about the layers

and all of this man‐made stuff.

Six levels.

‐ According to Curtis,

the Japanese placed specific layers of materials

above their buried vaults

to mark the pathway to treasure.

‐ Charcoal at 10 feet.

We got charcoal at 10 feet.

Marble.

We don't have all of the same stuff,

but we found what we thought was a concrete layer,

and then we found that layer of charcoal

about 3 foot down under that.

He had the same stuff.

My gosh.

I really don't want to get into digging up bones.

I heard about this stuff 20 years ago.

It just didn't seem real,

and now we're here, and we're digging,

and we're finding some of these indicators.

We're probably gonna see the other ones as well.

‐ Thnext morning,

John continues searching

for a tunnel entrance into the waterfall,

but 30 feet down,

Michele has uncovered nothing but dirt.

‐ We should be hitting it pretty quick here,

but getting a little nervous.

‐ To safely excavate the area,

Michele removes the dirt in a stairstep pattern,

reducing the possibility of collapse.

‐ I'm ready to go down there and have a‐‐

have a look‐see.

‐ How's the signal?

‐ It's pretty loud.

It's definitely in there.

You're gonna have to keep going deeper,

which means we're gonna keep having to go wider, too.

‐ Deeper and wider it is.

‐ John: Now I'm starting to get worried.

We should have seen it by now.

I don't know. She's scratching on something hard down there.

‐ Rob: What's happening, Michele?

‐ I've run into bedrock.

I can't dig any deeper.

‐ If we're hitting bedrock already,

there's no way we're gonna be able to get in this way.

Bedrock's not something that I can just get through.

I was hoping there's a tunnel down there,

but it's not promising it.

‐ Back at basecamp,

John gathers the team to discuss other options.

‐ I can't drill straight down

right at the waterfall,

and that's because that waterfall feeds

a water supply to the village down below.

I don't have many options there.

I mean, I have no options.

‐ What if we made our own tunnel

from the side of the mountain?

‐ How far from the site is it

to the void space?

‐ 930 feet

to the target under the waterfall.

‐ Wow.

That's a‐‐That's a long way.

‐ ‐

‐ 930 feet of digging a tunnel,

we would be here forever.

‐ I can't see just digging a tunnel 930 feet.

There's got to be an easier way.

There's lots of borehole cameras

that will make it 930 feet

to see exactly what we've hit.

‐ Once you know it's 100% in there,

then digging a 930‐foot tunnel makes a whole lot more sense.

‐ What about a horizontal drill?

They're often used to run pipeline

from one side of a mountain to another,

and I know they're well capable

of drilling over a thousand feet.

‐ A horizontal drill will allow the team

to run a borehole camera through 930 feet of hard rock

to see directly into the waterfall void.

‐ You're still gonna have a lot of problems

getting through there,

but I think it's your best bet.

‐ It's the best bet we've got right now.

It's the only thing we've got right now.

‐ In the U. S.,

head researcher Bingo Minerva

is searching for Yamashita treasure maps.

Since the tapes Rick's been looking through

suggest Robert Curtis had access to them...

...Bingo reaches out to a source

familiar with Curtis.

‐ So right now I'm in Las Vegas

on my way to meet Brian Greenspun,

who's currently the editor‐in‐chief

of the Las Vegas Sun,

the Pulitzer Prize‐winning newspaper.

Brian Greenspun had a lot of interactions

with Robert Curtis.

I want to see if he remembers anything specifically,

see if he gave him any maps, any details.

It would be really great to see one of these maps.

Hey, Brian.

‐ Hey. Good morning.

‐ Bingo. ‐ How are you?

‐ Good to finally meet you, sir. ‐ Nice to see you.

Welcome to the Las Vegas Sun.

My parents started it in 1950,

so it's been in my life almost my entire lifetime,

you know,

so I guess I'm the‐‐

I'm the keeper of the flame, let's say, right?

‐ ‐ That's‐‐That's my story.

We've been around a long time,

and we've had a lot of headlines,

but since you mention...

‐ Over its 70‐year history,

the Las Vegas Sun has won numerous journalism awards,

including a Pulitzer.

Well known for their in‐depth reporting,

they've covered the search for Yamashita's treasure

at length.

‐ So the reason I'm here today

is that I currently have a team in the Philippines

that's treasure hunting for gold.

We believe we're on a site

that is a Yamashita treasure site.

We've actually found evidence

of Americans being on the property

in what we believe is a Japanese tunnel.

‐ Okay. ‐ Now, through my research,

I found out that you wrote about Robert Curtis

back in the '70s

and that spanned for about three decades.

So really the question I have is,

how did you meet Robert Curtis?

What was it about his story that, you know,

convinced you to even start writing this?

‐ That's a simple question,

but it's a very complex answer.

So here comes a guy who walks into the office

noticeably frightened.

He wanted to talk in the car.

This was a guy who didn't trust anybody.

It felt to me like he was running for his life,

and then he starts telling this story

about that treasure

somewhere, hidden deep somewhere.

And so I had to figure out whether it was real,

so I spent a lot of time with Bob.

Why is he so afraid?

Remember, this is 1978.

Marcos was at the height of his power.

He was in control.

‐ President Ferdinand Marcos was reportedly brutal

in his obsession to find Yamashita's treasure.

After treasure hunter Roger Roxas claimed

he found a cache of Yamashita's gold,

Marcos allegedly imprisoned Roxas

and seized his treasure.

Roxas later filed a suit against Marcos

to try and recover his stolen goods.

Roxas died under suspicious circumstances

the night before the trial began.

‐ And, of course, as it came out,

Bob Curtis was afraid

because he'd got out of the Philippines

10 seconds ahead of being killed,

so he thought,

and he needed this story told in a most credible way,

believing that, once the story is out,

there's no reason to kill him.

‐ Robert Curtis first went to the Philippines

to assist in President Ferdinand Marcos' quest

to find Yamashita's gold.

After several months of working for him,

Curtis reportedly learned

that Marcos had grown suspicious of him

and ordered his assassination.

Curtis immediately fled the Philippines

and came directly to the Las Vegas Sun

to share his story.

‐ You have to be skeptical about it.

So even then, I mean, really, first impressions with you,

you didn't really believe this story.

‐ How could you believe this story?

‐ Yeah. ‐ Who's Bob Curtis?

He was a mining engineer from northern Nevada.

How did he get in the middle

of Ferdinand Marcos' hunt for a treasure?

But there's no doubt in my mind

that Bob Curtis knew

that he had gotten himself

in the middle of something really huge

and very dangerous,

that someone could kill him.

‐ In a deposition made in 1993,

during the Roger Roxas trial,

Curtis claims he was recruited by Marcos

to process recovered gold,

removing identifying marks

that could tie it to countries looted by Japan.

‐ President Marcos wished to talk to me

about the possibility of handling

the re‐melting of bars.

‐ Eventually,

Curtis was given access to Marcos' maps,

which supposedly led to Yamashita treasure sites.

‐ I was skeptical about his story,

and my job was to find out if this guy was real

and his story was real.

But...

Bob had tapes,

and Bob had memos, and Bob had maps.

Well, we happened to have the ability at the time

to get it authenticated,

and I did. ‐ So you're saying

he's brought you actual Yamashita treasure maps.

‐ I'm saying I saw maps

that he claimed were maps to where the treasures were.

And then he showed me pictures...

deep in these caverns

of things that purported to be boxes

that he said gold was in.

I don't doubt that the maps, whatever the documents were,

the conversations that were taped were real.

We never would have printed it in our paper

if we didn't believe it was true.

In his head, printing the story meant

that he was no longer vulnerable to being killed

because of what he knew

'cause now everybody knew it.

‐ Did he think in his mind, by printing that story,

it offered him a bit of a cloud of protection

for himself? ‐ Yes. Absolutely.

That's why he came here.

He said, "Let's make it as public as possible."

‐ Bingo Minerva is meeting with a journalist

who investigated Robert Curtis.

‐ So these are the newspapers, the actual newspapers

from Curtis and all the information

and whoever else we talked to.

It's all in these stories.

This was our first story...

‐ This is the very first story you printed from...

‐ That's the very first story. Yes.

Everything we learned that we believed was accurate

came from Bob Curtis.

‐ There's actually something I would like to show you

and get your thoughts on. ‐ Okay.

‐ I have, these tapes,

and this is Bob Curtis' dying declaration.

‐ Wow.

‐ So is that Bob Curtis' voice?

‐ I've got chills.

I mean, I have chills up and down my arms.

Yeah, of course that's Bob Curtis.

It's the same guy, and it's the same voice.

I heard this fear in this man's voice.

He was scared.

This confirms

everything that we believe

at the time we first met Bob Curtis

and what we proved to ourselves was true.

‐ On January 24th, 2004,

the Las Vegas Sun printed an obituary

announcing the death of Robert Curtis

at 74 years old.

His exact cause of death was never publicly revealed.

‐ Are you aware of any other leads,

any information that will lead me

to any Americans

treasure hunting in the Philippines?

‐ Well, in our stories,

we did‐‐we did write about a fellow

by the name of Chuck McDougald.

He's one of those experts

on this whole Yamashita gold story.

‐ According to Greenspun,

Chuck McDougald was close to Curtis

and knew his secrets.

‐ He could tell you firsthand

probably a lot of what Bob Curtis could tell you.

‐ Talking to Brian,

and the fact that he believed Robert Curtis,

I mean, that's further confirmation

that there is truth in Robert Curtis' story.

So unfortunately, Curtis is not with us anymore.

I really need to find somebody still alive

that knows more about this story,

and hopefully that person's Chuck McDougald.

If I can track down Chuck,

maybe he has the information for us

that can help us on our search.

‐ Back in the Philippines,

a K9 unit arrives

to investigate the possibility

the explosive booby traps are in the tunnel.

‐ There he is.

‐ Chad just called in Paul. He's a K9 handler.

His dog's been trained to smell for explosives.

We need to get this tunnel cleared

and get back to work.

We got to get to the end of this tunnel.

‐ So is this some type of shepherd,

or what kind of dog is this?

‐ Belgian Malinois.

These dogs are used in special forces,

special operations.

These are the top dogs

of detection, of detention,

of personal protection, everything.

They can pick up drugs and explosives

hidden in places you'd never think.

If there's explosives in this tunnel,

this dog will find them.

The best way to explain the sense of smell of a dog

is if you walk in a house

and somebody's cooking chicken noodle soup,

you smell chicken noodle soup.

When a dog walks in the house,

he smells every ingredient in that chicken noodle soup.

‐ While dogs were used in combat

as early as 600 B. C.,

they were not a major part of U. S. military operations

until World War II.

Over 10,000 dogs were donated to the war effort

and specifically trained by American forces

to patrol Pacific theater beaches,

detect land mines,

and deliver messages.

‐ Sit.

‐ This is what we've found so far.

Um, I want to see if he'll hit on it.

‐ Okay.

Sit.

Okay. ‐ Good Drago.

‐ Good boy. Good boy. Good boy.

‐ Yeah. He can smell it.

‐ So if there's more of those inside of the tunnel,

he should be able to pick up on those.

‐ He'll find it. When he walks in that cave,

he's gonna search everywhere, and when his nose hits,

he's either gonna sit like he did here,

or he birddogs

and his tail goes straight up and he stops,

and that'll tell us where it is.

‐ Okay. Well, let's get some gear,

and we'll head down into the tunnel.

‐ All right. ‐ You ready?

‐ Yes, sir. ‐ Levi: Okay.

The Japanese,

them burying mines into the ground like this,

they didn't want them to be found,

and they didn't want to hurt you.

They wanted to kill you.

That's what scared me the most.

Here, put that on, Paul.

This is a total different element

than what we're used to dealing with.

Usually when you go into these old tunnels,

you know, we have the potential of getting smashed by rocks

but not something where somebody put a bomb there

intentionally trying to wipe you out.

This is a whole different world.

This here, this is as far as I'm gonna go.

Don't touch any of that old timber.

It's all rotted.

‐ Paul, the mound was found right here,

so we're gonna try to detect from here back.

‐ Levi: I hope they're real careful back there.

I don't want something to happen

and me have to dig them out of here.

‐ Levi: It's hard saying

where the Japanese can put these booby traps.

There's so much different material

inside of this tunnel.

They can put it in the floor.

They can put it on top of the timbers.

They can put it behind the timbers.

‐ Where's the bomb? Find the bomb.

‐ Clear? ‐ Not yet.

‐ The dog has cleared the area

where the terra cotta mine was found.

‐ All right, Levi, we're going on ahead.

Y'all wait here.

‐

‐ Well, those guys just went out of sight.

I hope the ground's okay back there.

We haven't been this far in there.

They took the dog in.

They're seeing if they can smell

any other explosive devices.

I told them, if it gets too dangerous back there,

if it looks too shaky,

just to back out and get out of there.

We can always bring them back later.

I hope they don't find anything,

but chances are, if they found one,

there's probably a chance of them finding another one.

I certainly hope they don't,

and I personally don't want

to get my legs blown off in here.

I'd much rather be pulling treasure out of here

than somebody gets hurt.

‐ While the K9 team checks the rest of the tunnel,

Rick comes to check on the site.

‐ Well, what's the verdict?

‐ You got a clean bill of health in there.

‐ Well, that's great. ‐ That's good news.

‐ We cleared it as far as we could.

‐ How far did we make it in there?

‐ Couple of hundred yards past the mine

where‐‐that we found.

‐ We checked the whole thing out, then?

‐ Ground started getting shaky.

I didn't want them going way, way back in there,

but at least we know we're clear up to a certain point.

If we have to, we'll bring somebody back.

‐ Rick: So now we've got a Japanese land mine

in a Japanese tunnel.

Something needed to be guarded.

What were they trying to protect?

I don't think we're gonna know

until we find where this tunnel goes.

‐ Thanks again, man. ‐ Absolutely.

‐ Thank you, man.

Appreciate it. ‐ Yeah.

‐ The next morning,

Bingo calls to update the team.

‐ Bingo: So, guys, I met with Brian Greenspun.

He's one of the editors at the Las Vegas Sun.

Now, he published a number of articles

on Bob Curtis and Yamashita's treasure

over the span of about three decades.

Bob Curtis, he provided a lot of evidence

to the Las Vegas Sun and Brian over there,

and unfortunately they don't have any more

of that archival evidence or documents left over.

What Brian did reveal was potentially a huge clue

with the name Chuck McDougald.

Chuck McDougald, I did some digging on him,

and I found out he was actually working

with Bob Curtis.

He was working with him on a site

called Fort Santiago,

and I found some archival news footage of him,

and I want you guys to check it out

and see what you think. I've already sent it to you.

‐ Okay.

‐ Wow. That was pretty interesting.

‐ He talked about maps.

It makes me wonder if he actually has those maps still.

‐ If he has those maps still, then maybe‐‐

maybe he has a map of our mountain.

Is there any way that we can get

to talk to Charles McDougald?

‐ Well, I tracked this guy down.

He's still alive.

He's living in the Bay Area currently.

He's my next meeting.

If I can get any information at all,

I'll let you guys know. I'll see what I can find out.

The key that will lead us to finding this treasure

could be just one person.

Hopefully that person is Chuck McDougald.

‐ Narrator: On the next "Lost Gold of World War II"...

‐ John: This horizontal drill may be our best bet

to see inside this mountain.

It's not looking too good.

‐ Geo: Hey, Levi, what is that?

‐ Is that a tooth?

You think it could possibly be a human?

‐ I had two original maps of the treasure

found in Marcos' office.

‐ Do you still have the maps?

‐ Yes, I do.

‐ Wow.

I've never seen anything like this.
