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

‐ Look at this!

There's light coming through here.

That's gotta be the surface.

‐ What is going on?

‐ They were willing to do whatever it took

to find this buried treasure.

If I were you, I would be very, very careful.

‐ This isn't just a natural occurrence.

If they put it there, we can get to it.

‐ I think you keep drilling

and see what you can get out there.

‐ If you're looking for an access point into here,

your best bet is through this spot.

‐ Under our feet is a huge void space.

The Back Door is gonna get us in this mountain.

‐ 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 WWII

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...

‐ John: This waterfall is hiding something.

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

‐ John: We are in the mountain, boys!

‐ ...and a location known as the Back Door.

Can they finally discover the...

‐ Five months into their painstaking search,

John and his team are working multiple sites

as they race to locate Yamashita's treasure.

At the bore hole site, his brother Rob

is trying to reach a treasure chamber

they hope lies 300 feet below this dense rock.

But there's a problem.

Their drill's been knocked off course,

and they desperately need to get it back in line.

‐ We need to make corrections

in order to try to bring that back

and aim right where we gotta go.

Andrew, we ready to fire it up?

‐ They must be precise,

since they hope to drop a camera through this hole

to see inside the treasure chamber,

a chamber that's still 700 feet away.

‐ We're gonna make our speed and pressure adjustments,

drill a bit, then we'll send our survey tool down

and see if we've actually made an impact.

‐ To ensure they're on the right path,

they check a core rock sample.

‐ This is our most recent sample here.

It looks like we're going right back

through some really good rock.

This is a giant relief to see this.

I was really worried about whether or not

we were gonna come back into some stable enough rock

that we could actually even make the corrections,

and right now it looks like we will.

‐ Meanwhile, over at a second location

known as the tunnel site,

father and son miners Geo and Levi

encounter another roadblock.

‐ So inside of our tunnel we actually had

another collapse that we came into.

We were assessing whether we should try to go around it

or look over the top of it

and see if we're gonna go through it.

Turn your light off real quick, Geo.

There's light coming through here.

‐ With the tunnel blocked, they ask Rob

to join them for a smoke bomb test to find the opening.

They hope it reveals another way into the mountain.

‐ 10 minutes from now I'm gonna throw this thing, okay?

‐ Okay, sounds good, man. ‐ All right.

‐ Their goal‐‐ locate a tunnel maze

inside the mountain leading to treasure.

‐ It would be extremely difficult

to find where this opening might be underground.

Here we go.

So I'm gonna go up in the air with the drone.

We're gonna send smoke coming out of that opening,

see if we can find out exactly where this opening is,

and then we can go up there and explore it.

‐ Geo should've set it off by now.

Should be getting smoke any time.

Can you come in super wide on that?

Hopefully we can see some sort of smoke

coming out through the canopy.

Man, I'm not seeing anything yet.

‐ Yeah, it can take a little while for that smoke to rise up,

especially through a canopy like this.

‐ Whoa, whoa, whoa. Stop, stop.

What's that right there?

‐ That's smoke, all right.

‐ Wow, look at that. That is a huge hole, man.

‐ I'll mark the GPS coordinates.

You can put them right in the handheld,

walk right over there. ‐ That's awesome, man.

‐ As Rob and Levi find a promising lead...

heavy machine operator Steve

tries another way into the mountain.

‐ That was a big one.

‐ He's at a place the team calls the Back Door site.

They found it last year and think it could contain

an entrance to the tunnel system.

‐ Is it the entrance?

‐ I don't see anything in here.

‐ But they couldn't find an access point.

After a new scan,

they've pinpointed a possible way in.

‐ I think that if you're looking for an access point into here,

I think your best bet is through this spot.

‐ But Steve has to get past a big obstacle

before he can begin digging.

‐ I gotta take a look at this.

I have a really unstable foundation for this rock.

‐ Whoo!

‐ If this boulder falls into the hole,

it will completely block him from getting into the back door.

‐ It's only a matter of time before it's gonna cave in.

I get one shot at this.

Come on baby, come on.

We can get it.

A little bit more. A little bit more.

[ falling metal clangs ]

Yeah!

I got it!

Whoo‐hoo!

I was able to slide it back,

but I almost flipped the machine doing it.

That was the scariest thing that I've done in a while.

‐ John and Rick join Rob and the miners

as they follow GPS coordinates...

‐ Right up that way.

‐ ...towards the other tunnel opening

the smoke bomb revealed.

‐ John: We need to find out

what's going on with this tunnel.

Hopefully it's gonna help us get one step closer

to the void space under the waterfall,

one step closer to, you know, solving this mystery.

‐ Rick: Hey, over here, guys!

‐ Wow.

We got a heck of a hole here, don't we?

This is ugly.

‐ Rick: Yeah, it is.

It certainly wasn't what I expected.

‐ Looking at it right now, we have a mess.

It's just a big giant hole.

I don't know if it's so much a collapse.

I won't be able to tell till I climb down inside this hole.

‐ Geo: Man, be careful.

‐ I see a lot of rotten timbers.

‐ More round stock with numbers on them.

‐ Levi: I don't know what the numbering means at all yet.

This is clearly the same type of timber

and same type of markings they had

on the other end of the tunnel where we were at.

‐ In the team's early exploration of the tunnel,

they discovered numbers etched

into the round stock support posts.

‐ Stop right there.

It almost looks like on the post

there's, like, these numbers.

‐ Despite the presence of Western numbers,

multiple pieces of evidence support the idea

this tunnel was built by the Japanese.

‐ I think it's Japanese A3 landmine.

It's made out of terracotta.

‐ The team theorizes these numbers were left

by American POWs forced to work in the tunnel.

‐ I can almost see the end of the collapse.

I think that's where we were seeing daylight through here.

‐ Didn't see any kind of offshoot, something?

‐ This is it. This is the end of the line.

I honestly don't think the tunnel goes anywhere else.

‐ You're telling me this is a tunnel

that just goes right through the mountain?

‐ I think this is the beginning of our tunnel

that goes through the mountain.

‐ That doesn't make any sense.

Who would tunnel right through a mountain?

‐ I have no idea, man. All I know is this is a tunnel

that leads absolutely nowhere.

‐ If the tunnel simply cuts through the mountain,

it will not lead to the treasure they seek.

‐ It's not making a lot of sense to us right now.

I mean, this was a lot of work to run this tunnel

through the mountain like this.

So we're going to regroup, try to put our heads together

and maybe make some sense of what this tunnel is.

‐ The next day, despite this blow,

work continues at the back door,

which the team hopes will lead to a tunnel,

possibly connected to the waterfall void.

‐ Your best bet for an access point into here

is through this spot.

‐ But heavy machine operator Steve faces a new challenge.

‐ Ah.

Digging was‐‐It was easy.

Now it seems like I'm just hitting something really hard.

‐ Hoping to break through the solid ground,

they bring in a new tool‐‐

the Hammer of God.

‐ Let's see what we got.

[ machine chugging ]

‐ Guys! ‐ Yeah!

Ha ha!

Oh, yeah!

‐ That's gonna do it.

We've got the right tool now to get in there.

‐ We got some work to do now, buddy.

Let's get down there, get this thing going.

‐ Let's do it! ‐ Yeah.

I believe that we're gonna get through that rock.

‐ Capable of striking up to 12 blows a second

with over 4,000 foot‐pounds of force,

they're banking on this hammer to get them

into a possible void space spotted by the tech team.

‐ Being able to come down here to the Back Door

has just been a deal‐changer

because we are feet, literally feet away

from getting into this mountain.

We're gonna find a way into this void space

under the waterfall.

‐ Back at the bore hole site,

the drill is now 400 feet in.

The team needs to constantly monitor core samples

to ensure they remain on the right path.

‐ We're pulling another core sample now,

and then we're gonna keep on going.

What the heck?

That isn't good.

Well, we were in perfectly solid rock before,

and now there's a bunch of sand and dirt in the end of this.

Andrew, what do you make of this? This is sand!

‐ It doesn't make any sense with the core.

It goes from solid rock to sand to solid rock again.

‐ Yeah.

‐ The discovery of sand inside the mountain

rings alarm bells for John.

‐ The Japanese were infamous for putting sand traps in.

‐ Tons, hundreds of tons of sand, enough to kill a man.

‐ According to legend,

the Golden Lily placed sand traps

next to their treasure sites,

awaiting the unsuspecting diggers

who accidentally punctured the seal.

‐ It's my theory

that there is a tube filled with sand

and, if you got too close,

the sand would slide down the tube and bury you.

We could be getting really close to that treasure.

If we're hitting this sand, it means that we're getting

particularly close to this void space

that's underneath the waterfall

and could possibly be the treasure room.

‐ That evening, with puzzling new evidence

suggesting their tunnel

may be just one singular passageway...

‐ I think this is the beginning of our tunnel

that goes through the mountain.

‐ That doesn't make any sense.

Who would tunnel right through a mountain?

‐ ...the team calls military historian Craig Gottlieb,

who has helped solve other mysteries on the mountain.

‐ What you've got is the magazine body

of a Japanese Type 99 Arisaka rifle.

‐ Narrator: ...to see if he can provide any insight.

‐ Craig, the tunnel that you were in when you were here,

uh, we happened to run into another entrance,

and it's directly on the other side of the ridge.

It looks right now like this tunnel

just goes right straight through the mountain,

under the ridge, and that's it, man.

It doesn't go anywhere.

‐ Was it just a tunnel straight through

from one side of the ridge to the other?

‐ As close as we can see right now,

when we found the new entrance,

we didn't get very far in there

and there was a huge cave‐in.

But you can see light all the way through.

So right now it looks like there's nothing off to the side.

There's a possibility,

but right now it looks like it just goes straight through.

‐ Okay, well, you know, what you're describing‐‐

and I really don't know a lot about treasure‐‐

but what I do know about is Japanese fighting tactics,

and that's a typical Japanese fighting position.

They could pop out on either side of this ridge

and engage enemy forces.

And so, when you tell me there's a tunnel

going straight through a ridge, uh,

that says to me this is a tunnel

that was built specifically to fight.

‐ Narrator: In the early days of World War II,

Japanese tunnel warfare was nightmarishly effective

against Allied forces.

Just a few dozen Japanese soldiers

operating in a connected series of tunnels

could inflict massive casualties,

moving from one protected firing position to another

without ever coming above ground.

‐ We found a disarmed landmine on one end of the tunnel there.

Do you think that was just so

somebody couldn't back‐door them?

‐ You know, that's very typical.

You'd find explosives on either side of a tunnel, and yeah,

they would booby trap the tunnel entrances.

‐ Well, that'd make a lot more sense.

‐ Well, sorry I don't have better news for you,

but everything you've described for me,

the tunnel has every hallmark of being

a Japanese tactical fighting position,

a Japanese fortification.

So I wish I had better news.

‐ Well, you've really shed light on

what this actually could be.

‐ I'm happy to help.

‐ Narrator: Despite Craig's disappointing news,

John's determined to pivot,

using a new tool recently obtained

by their U. S. researcher Bingo‐‐

a map of the mountain

with clues to many possible treasure sites.

‐ John: The Japanese were known for building

protective, defensive locations.

What is it you're trying to protect? The treasure?

The entrance to the treasure?

Maybe this tunnel was built by the Japanese

to protect what was going on underneath the waterfall.

I'm more fired up than ever.

We're gonna get under that waterfall.

‐ As a new day dawns,

at the Back Door site,

the battle against dense bedrock continues,

and the Hammer of God is losing.

‐ Steve, maybe over a little to your left,

maybe a couple of feet. I just, uh‐‐

If I can hear a little echo, you know,

like the back side of that void space,

just drumming a little bit,

that would be awfully encouraging.

‐ I've been hammering this whole area, Rick.

I haven't heard anything hollow, but, you know what?

I'll go as long as you need me to go.

This rock is beating the hell out of my machine.

It's beating the hell out of me,

and right now I just think I'm chipping into a dead end.

‐ Yeah, Steve, I'm not hearing anything.

Maybe we should be talking about this, I suppose, huh?

‐ I'm gonna shut the machine off

and let's, uh, let's discuss this.

‐ I'm not getting anywhere.

There's no edges. If you can look, there are no edges.

There's no splits. There's nothing.

This is a solid piece of whatever.

I mean, this right here,

took me an hour to get that piece.

‐ This stuff is really hard.

But we need to get access into this mountain.

We don't have it anywhere at this point.

I still think this is our best bet.

I am just absolutely convinced

we are within just a few feet of getting in there.

‐ Rick changes tactics,

swapping their massive hammer for a backpack drill.

‐ What we're doing with the backpack drill

is trying to get a hole down into the void space.

If we can do that,

then we can get a camera down the hole,

have a look at how far we've got to go.

Then we can crank that thing up and get going again.

We're getting there inch by inch,

but it's not easy.

This is really hard rock.

And the backpack drill, it's all human power.

[ drill shuts off ]

We've got to be right there, man.

We got to keep pushing on that thing.

‐ I'm pushing. It's not gonna go any harder.

‐ Come on, buddy. Give it one more try.

‐ The ground is really hard. I mean,

I knew going into it that it was going to be hard.

And, uh, I get to a certain point

where I thought it was getting softer,

and then it just sort of seized everything.

‐ I've been pushing Steve really hard on this project.

It's just hard work.

We've got an awful lot of hard rock to get through,

We're not gonna get through it by just staring at it.

We've gotta work at it really hard.

‐ Rick...

it's...

Aah!

‐ Come on, Steve! Keep pushing that thing!

‐ Come on, Rick! I'm trying, look!

‐ Push it!

[ engine stops ]

‐ Just killed it, Rick.

‐ Try it again.

Rich, this thing's done.

I'm done. I'm done. This‐‐

‐ [ sighs ]

‐ I can't do it, man. Finished.

I'm not one to quit.

This entire mountain, this island

has pushed me to the extent of all my limits.

‐ We're so close.

‐ You need to get a new drill, Rick.

I'm done. I tried for you, pal. I'm sorry.

‐ It's a devastating blow.

Another promising lead is a dead end.

‐ [ sighs ]

I think that maybe I'm just pushing this whole, uh,

Back Door thing too hard.

Maybe John's right.

Got to be a better way in here. I don't know.

‐ Back at basecamp, John and Rob

turn to a Golden Lily treasure map for fresh clues.

Their stateside researcher Bingo Minerva

received it from their new partner,

renowned Yamashita treasure hunter Chuck McDougald.

‐ Those two are the original maps.

‐ These are incredible.

I've never seen anything like this.

‐ Yeah. ‐ In any of my research.

‐ The brothers hope to find new locations to pursue.

‐ You see this big diamond shape here?

It's like the next prominent feature on this map

that we have no clue about.

Chuck, there's a diamond, a dark diamond box there.

Do you have an indication,

or do you have an idea of what that means?

‐ Chuck: Every symbol on these maps means something.

‐ If we can find that, I think we can start to figure out

the rest of this stuff here pretty easily.

So Rob and I are looking to see

if we can find what this diamond on the map represents.

‐ We've got GPS marked out for each one of these points,

so I've got a pretty good reference

as to where this area is.

I'll get the drone over top of it,

and we'll see if anything jumps out at us.

‐ Using the drone to help ascertain

what some of these things on the map actually are

has been really working out well.

I'm hoping that we'll have the same luck here.

How you doing?

‐ Nothing but treetops so far.

It's not easy to spot something on this mountain,

so we're really gonna have to comb through systematically

to make sure we've peeked through every little hole

that we can in this canopy

and see anything that is out there.

‐ Anything?

‐ Oh, hang on. I see something.

Let me back up a second, get over the top of it.

‐ What do you got?

‐ It's hard to say. Let me get a better angle on it.

‐ That's definitely something.

Look at the sharp edge on that thing.

‐ It looks like a wedge.

‐ Can't believe‐‐It's sticking up above the treetops.

All right, take a GPS lock on that.

Rob just spotted a very unique feature above the canopy.

I've never seen a stone or a boulder

sticking up above the treetops.

That's certainly something out of the ordinary here,

and it's right in the area where this diamond is depicting

it should be in line with Breach 6 and the river.

So I think it's in our best interest to get out there

and explore this option, go see what that is.

‐ At basecamp, head researcher Bingo

checks in with John and Rick.

Recently, the teams experienced unnerving surveillance...

‐ You seeing that, Rob?

Helicopter coming in.

‐ So Bingo met with Roland Kelts,

a journalist obsessed with Yamashita's treasure,

to see who might be monitoring the team's work.

‐ You know, to really understand

the story of this treasure,

uh, and how deep and how distant it goes,

you have to go back to General Douglas MacArthur.

‐ Roland has spent years

researching Yamashita's treasure

and the many powerful organizations pursuing it.

‐ What I learned from Kelts, you know,

organizations like the OSS, or even now, CIA,

they've had their eyes on this treasure

ever since after the war ended.

‐ You hear these rumors, you know,

but nobody ever has come up with documentation.

I've always thought it was just a conspiracy theory.

‐ Well, we're talking an insane amount of money here, guys.

I have reports here from General MacArthur,

and he goes on record saying

that not only did he declare himself the SCAP,

or the Supreme Commander of Allied Power,

I mean he goes on to talk about that he controls

and has custody over any Axis property,

precious metals, and stones

belonging to the Japanese government.

MacArthur knew about the treasure.

He told President Truman.

How high does this go?

‐ Bingo, it really begs the question,

who's still looking for it?

‐ I asked Roland if he thought that if the CIA

or maybe any other organizations

are still interested in this treasure,

and he told me that,

if there's still treasure out there to be found,

they are very interested in it,

and he told us to be very careful.

‐ Bingo, you're not making me feel any better

about these random helicopters

that come cruising over our project site.

I always try and just ignore it,

but man, who knows who they are?

‐ Yeah, I know we were worried about that,

worried about people watching us,

worried about what kind of dangers we might be in,

and I think we were right.

I mean, we've been warned multiple times.

‐ You know, now I think we need to be a little more diligent

in what we're doing and really keep an eye on it.

When you're talking about billions of dollars of gold

that's buried in a mountain,

everybody's gonna want a piece.

And that's really kind of unnerving.

We have enough people watching us here,

and we have to be very careful about how we proceed.

‐ The next day, John and Rob look for the landmark

they spotted earlier with the drone.

‐ That's definitely something.

Look at the sharp edge on that thing.

‐ Since it corresponds

to a symbol on McDougald's map,

the brothers hope it could be

a new access point into the mountain.

‐ We've gotta be getting close.

‐ We're real close. It's gotta be somewhere right around here.

‐ We saw the tip of it, so it's gotta be right in this area.

All right, I think we should split up.

That's the best way to find it.

There's just too much woods here.

This place is so thick, with the top of that rock

stuck up through the canopy. The drone saw it.

And so far, that's what I'm looking at,

the top of the canopy more than the bottom

because you can't see nothing down here.

So gotta keep looking, We're gonna find it.

Are you kidding me?

Hey, Rob, you got a copy?

‐ Go ahead, brother.

‐ Follow the trail back the way I came.

You gotta see this.

It's another pyramid.

If this is anything like the one at Breach 6,

it's pointing to something.

It's hiding something around here.

‐ Narrator: According to the Golden Lily code,

pyramids point to treasure sites.

It was the first clue

an eyewitness told John to look for

when they came to the mountain last year.

Following where the pyramid pointed

led the team to Breach 6.

John hopes this new pyramid

will also lead somewhere significant.

‐ This is exactly where that point came up out of the woods,

That's what you saw with the top of the drone.

It's gotta be this diamond right here.

You know, this rock wouldn't be on the map

if it wasn't significant.

The spine of the pyramid makes me think

that it's pointing somewhere.

And when you look at it in correlation

to the map that we have, it looks like it's pointing

to what this upside‐down U‐shape is along the river.

So we'll have to follow it straight

and see what we're gonna find.

If we can crack this code, this could be it.

This could be the way in.

‐ On the mountain,

with progress at other sites stalled...

‐ Timbered‐up, toothpick, caved‐in mess.

‐ I can tell you right now,

doesn't seem to be any treasure in this hole.

‐ Just killed it, Rick. This thing's done.

‐ ...the waterfall is currently the most promising option

for uncovering treasure.

So Rick helps the team get to the bottom

of an odd discovery made at the bore hole site.

‐ What the heck?

Well, we were in perfectly solid rock before.

Now there's a bunch of sand and dirt in the end of this.

‐ To get answers, he looks through the Bob Curtis tapes.

‐ Bob: I showed him the map of that site.

This is all at an angle like this.

When you cut through that, you break‐‐

you break the sand.

It was a trap that, uh, that we walked into.

‐ Narrator: The tapes reveal

Curtis and his team encountered a sand trap

while digging for gold in Fort Santiago.

For more insight, Rick turns to the only other

living person who was there‐‐ Chuck McDougald.

‐ Well, Chuck, on our site up here,

uh, we've been drilling.

We're trying to shoot for the treasure chamber.

We're getting a ways into the mountain now,

and we've run across something a little bit unusual.

We encountered some sand in an unusual location.

I mean, we had solid rock, sand,

and then solid rock in our core drilling.

Can you tell me anything about that?

‐ Yes.

We encountered something similar at Fort Santiago.

‐ Narrator: On February 8, 1988,

Robert Curtis and Chuck McDougald

began a covert expedition,

allegedly funded by President Aquino,

to search for Yamashita's treasure

at Fort Santiago in Manila.

Keeping out of the public eye,

they led a team of local Philippine workers

to dig a shaft straight down towards the treasure chamber.

‐ At about the 30‐foot level,

we were in very thick clay.

And all of a sudden, sand started trickling out

from the side of our, uh, tunnel.

We didn't know what to think about it,

but we went ahead and kept digging.

And about...

5 to 10 minutes after that trickle occurred,

our whole tunnel collapsed and, uh,

burying two men inside the tunnel and killing them.

This happened on February 12, 1988.

‐ It was a trap that‐‐ that we walked into.

Uh, it was heavy, wet, moist clay,

which is‐‐which weighs tons, just slides down.

And this is what happened‐‐ we had a slide this way,

a slide that way, a slide this way,

and it was a repeat‐‐ repetitive thing.

And that's, that's why we couldn't save the men.

‐ Uh, they were good friends of mine.

I'll never forget it.

‐ I'm so sorry to hear that.

‐ Narrator: After the tragedy,

Curtis and McDougald faced criminal charges

in a Philippine Senate hearing

formed to investigate the incident.

‐ Man on recording: When we get through,

I think the public will be able to view a room

that hasn't been seen in at least 45 years.

‐ Narrator: The deaths were ultimately ruled an accident

and the Fort Santiago excavation continued.

‐ So this was kinda set up like an‐‐

a booby trap, then, actually.

‐ That was a booby trap.

We learned the hard way about that one.

Then we continued after three weeks

digging straight down,

and that's when we encountered gold flecks.

‐ Narrator: Many believe the deadly sand trap,

allegedly crafted

by the Japanese at Fort Santiago,

may have been inspired by ones created by ancient Egyptians

to protect vast amounts of gold and jewels buried in tombs.

‐ My mining engineers,

after the‐‐ after the accident, uh,

were able to confirm that it was a well‐placed trap,

just like the Egyptians did with the pyramids.

‐ All right, just remember,

uh, the sand could indicate some kind of booby trap,

or it's maybe just an indicator

that you're near the treasure.

‐ If I'm‐‐if I'm hearing this correctly,

we're getting close. We're getting almost there.

‐ Yes. We don't know how close yet, but you're close.

Uh, just one more word to the wise.

Once you know you're in the area,

slow down and be very careful

how you approach the actual treasure.

I guarantee you it's booby‐trapped.

‐ Chuck, I just can't tell you how much I appreciate this.

I mean, this kind of information

is impossible to get anywhere else.

Having somebody like McDougald on our side

who's willing to give us the information

and share his experience and his failures

and the things that happened to him

is just a wealth of information.

‐ Up the mountain, John and Rob

pursue a promising new find inspired by McDougald.

‐ Well, if you look at the map,

to me, that upside‐down U

could be a tunnel entrance in the water.

‐ Narrator: A scan of the area revealed a landmark

they believe is a directional marker.

‐ You know, this rock wouldn't be on the map

if it wasn't significant.

It's gotta be this diamond right here.

It looks like it's pointing to what this

upside‐down U‐shape is along the river.

‐ John's determined to uncover what could be hidden here.

‐ Man, it's thick as thieves in here.

Whoa.

We've gotta be getting close.

‐ Yeah.

‐ So we're thinking the spine of the second pyramid

is pointing in the direction to tell us where to go next.

If we can decipher everything on this map,

we might be able to get right to that treasure.

This map could be the key to solving this mystery.

So we're gonna follow this direction, where it's pointing.

I'm gonna see where it leads.

Holy crap. Look at this, Rob.

That rock there. ‐ It's huge.

‐ It looks like a temple.

Geez.

Holy...

What is this place?

Whatever this thing is we're not sure,

but it lines right up to the pyramid,

so we'll just keep following the map

and going for it.

Creek looks like it's rolling right that way.

Might as well follow this creek down through there.

‐ John and Rob are looking for a landmark along a river

to match McDougald's map

when they finally arrive

at one of the mountain's lower waterfalls.

‐ Look at this place.

Now, on the map, the second pyramid is pointing

right towards where the sign of this U is,

and it led us right here

to a significant waterfall area.

This has got to be the spot.

‐ What are we looking for?

‐ Start looking at every single rock

'cause, if this is the right place,

there's a marker here somewhere.

Rob and I are gonna scour

every single boulder in this place...

see if we see any signs that the Japanese were here.

‐ Evidence suggesting

a Japanese presence at this waterfall

would confirm to John

this is the location corresponding to the map.

‐ Hey, John!

Look at that.

It looks like another little monkey head.

It's right here.

You see his nostrils, his two eyes,

his nose, and his mouth.

‐ That's the sign we're in the right spot.

‐ Face markers are an important symbol

in the Golden Lily code.

‐ What does it look like?

‐ Like a gorilla's head.

‐ Believed to mark the location of treasure,

a gorilla face is present at the other waterfall

where metal deposits were found.

After a series of disappointments,

it's a heartening discovery.

‐ Right on top of this big rock.

See that square?

A box marker.

‐ This? ‐ Yeah.

‐ In addition to the gorilla face

and box marker,

John spots another sign of possible human activity.

‐ This little cubby over here,

there's a lot of fractured rock right there.

There shouldn't be fractured rock.

That should be all cobbles.

Everything else around there is weathered and smooth.

All these signs...

all these symbols...

All pointing to this location.

What is the significance of this place?

‐ On the finale of "Lost Gold of World War II"...

‐ Rick: I think we're just about ready to break through.

‐ After five months of backbreaking excavation...

‐ Come on, Steve, push it!

‐ ...it all comes down to this.

‐ We're so close,

and we're gonna get it.

‐ And shocking new clues...

‐ Chuck, are there any indicators

that gave away the location of these maps?

‐ Yes.

...lead to the discovery

of even more hidden treasure sites.

‐ Six fingers.

‐ We're not just dealing with one treasure site anymore.

We're dealing with multiple treasures.

‐ Will they recover Yamashita's infamous treasure

and finally solve...

‐ Is that what I think it is?

...this great mystery of World War II?

‐ That's the symbol for gold.

This could be it.

Oh, my God, I can't believe we're seeing this.
