[narrator] Previously on Mystery at Blind Frog Ranch.

We gotta find that dry entrance. Let's go.

[Chad over radio] There's the hole, right there.

[laughs]

[Eric] If we can find the radioactivity.

If we can find the dry entrance to the cave.

- [beeping] - There's a hit.

I think we need to go check it out.

We've got two targets right now.

Here we go, here we go. That's it, right there.

Wow.

But look how black all the rock is.

[device whining]

- [Eric] We can only dig a relatively small hole. - Wow.

So we need to be dead-on.

There could be a cavity underneath us here.

[Charlie] Could this be a smelter?

Yeah, they could have smelted the gallium up here.

I mean, we're literally standing on top

of an ancient cache of something.

[Duane] There are some places on earth that just don't seem...

right.

The land feels different.

It acts different.

And this, here, is one of those places.

Some say the land is trying to hold on to something.

Don't go in the [bleep] cave.

[Duane] Aztec treasure?

Holy [bleep]!

[Duane] Caverns of gold?

Look at this!

[Duane] Mormon riches.

It'd be million dollars here.

[Duane] Some even say there's a buried space ship

Hell, yeah.

Me? I never cared much about the stories.

I just care about finding whatever the hell's in the ground.

What's the matter?

- Hey. - Hey.

[Eric] How'd it go?

I thought pretty good. Yeah.

We had some good readings on the gravity meter.

- Did you really? - We started seeing some interesting ones,

some highs, some lows.

So, we'll go back and take a look at 'em.

So, my goal here is to use these geophysical tests

to narrow in to an exact spot where we can get into this cavern.

Well, the radiation drone

gave us a general area where we might find somethin

Then, the gravitometer indicated several points

where we might be able to get into this cave system

But these readings are still not accurate enoug

to pinpoint a drilling location.

I'm confident, though, that,

you know, with a few more tests,

we might be able to say, "X marks the spot."

[Chad] Good.

You know, over on that ridge, I think I found a smelter.

It's got, like, a firepit-looking thing.

- I don't know what it is. - Really?

Yeah, yeah. It looks old as hell.

[Eric] Is it made out of rocks?

Yeah, yeah. There's black soot all over the rocks,

and all kinds of [bleep].

I don't know if it's been broken apart or what,

but it looks like a smelter, though.

[Eric] Over in this area?

Yeah, where me and Charlie were looking.

I'd like to see that.

[Chad] You want to go check it out?

Yeah, let's go now. We're losing our light here.

All right. Yeah, yeah. Follow me.

- [Duane] I'll see you guys later. - [Chad] All right!

Yeah, it's just right over there on the cliffside.

[Eric] Okay.

About how far?

[Chad] I don't know, half a mile.

Okay.

Awesome.

- Lead the way. - All right.

Yeah, this is something I didn't...

I've never seen it out here before, and it was just

crazy. I saw it from an airplane.

[over radio] Just along that ridge.

[Chad] And what it looked li to me was this hole,

like a... like a cavern.

- [Eric] Uh-huh. - [Chad] Like a dry entrance really.

- [Eric] Okay. - [Chad] But, when we finally get over there,

it looked like a fireplace.

[Eric] Oh, nice.

[Chad] Yeah, right over here.

Look at this [bleep].

Yeah, it's right here.

- Look at that. - Oh, yeah!

[Chad] You can see the black. It goes all the way up there.

[Eric] Yeah.

Your first thought is,

was this a little place where somebody camped?

But, it doesn't look like a very good camp spot to me.

- It's not level... - Right.

um, and so, the way the rocks are formed, it could

form sort of a, um,

almost like a furnace.

Obviously, you can see the smoke stain there

- Right. - You can see the outline

- of what may have been a kiln right here. - Right.

This looks like it was patched with adobe,

and it was probably, at one point,

a lot more extensive than this.

Like, deeper, or bigger, or something like that?

It was probably built up. You make a kiln sort of

- shaped like, almost like a beehive. - Right.

- And you give it the right venting. - Yeah.

- And so, you create, sort of, a blast furnace there. - Gotcha.

[Eric] Smelters were used in Utah in the 1870s,

for smelting gold, silver, and zinc.

They were blast furnaces

that looked like giant beehi adobe structures.

Maybe this was a smaller operation with smaller ovens.

Or, maybe this site here is considerably older.

I just don't know.

[Chad] Well, do you think that they could have

smelted the gallium here?

[Eric] Well, if this is a smelter,

which I think it was at one point,

in these instances, you want to smelt the material

as close to the source as possible.

So the mine could be super-close to here, right?

Yeah. I mean, the mine entrance could be

- anywhere in here, or the cave entrance. - Yep.

In fact, the spot where your dad and I

were using the gravity meter today

is just over that ridge.

[Chad] Right.

[Eric] We had some anomalies over there

with the gravity meter, and so,

um, I think we're right...

We're right in the right zone, here.

- May be worth taking a look, right down here. - Yeah, yeah.

[Eric] When you're processin any kind of ore,

and in this case, smelting it,

you want to have that smelte located as close as possibl

to the cave or mine entrance

for obvious reasons of efficiency.

There's just no reason why you'd want to carry

that material any extra distance.

So, we might just be near a mine or cave entrance,

where they were pulling out material

that they were smelting.

Normally, with cave entrances,

or if there's something valuable underground,

- you're not going to want to leave it open. - Right.

You're gonna want to hide it.

Sometimes, they'll put wood, like logs, over it,

and then fill it with dirt.

Right.

Uh, break some vegetation, things like that.

Oh, [bleep]! Look at those!

- Look at those bats! - Ooh!

- Those are bats? - There's a whole flock of 'em, right there.

- See those? - Oh, my God. They're huge!

There's so many of 'em! Wow!

Well, you know that bats, where they live.

- They live in caves. - Yeah, yeah, yeah.

So...

[Chad] We need to follow those bats, huh?

[Eric] We need to find out where they're coming from.

Let's go around the corner, here.

[Chad] Yeah, yeah, see if there's more coming out somewhere?

[Eric] Yeah.

Oh, yeah.

- Chad? - Huh?

[Eric] Let's follow this wash, here.

Sometimes, faults will follow these canyons.

- These little canyons like this? - Right.

And so, we're looking at a possible weakness zone in the earth,

and maybe this is where the cave is.

- [Chad] Okay. - Yeah.

Just follow it up.

[Chad] Look at that.

[Eric] Oh, wow!

- Whew! We may be close here, Chad. - [Chad] Look at that.

[Eric] Is this the general direction

you think those bats came from?

[Chad] Yeah, it was right in this area, for sure.

[Eric] All right.

[Chad] It's getting thick. Man!

[Eric] Up in here?

[Chad] Through up here? Yeah.

Anything?

It's like getting hard to see in there, it's so thick.

Look at this.

- This looks promising. - Yeah.

[Eric] Well, look at these ledges.

See that?

- [Chad] Yeah. - See how the water has just carved 'em?

[Chad] Right.

[Eric] You got, like, potholes forming in here.

[Chad] Right.

You're saying a cave could go in there?

[Eric] Yeah.

Anything in that crevice, right in there?

[Chad] Ah, not really.

[Eric] Gotta be getting close.

[Chad] Holy [bleep]!

Look at this! Look at this!

[Eric] Ooh!

[Chad] That's another one right there, isn't it?

[Eric] This looks like another smelter.

[Chad] Wow!

[Eric] There's more smoke stains on the rock.

- [Chad] Yeah, there is. - [Eric] That's crazy.

[Chad] No [bleep] way! Look at this, Eric.

We got another one, right here.

[Eric] They're so close!

[Chad] So if there's two of these right by each other,

- then this might have been a big operation, huh? - [Eric] Yeah!

There's nothing in there.

[Chad] Holy [bleep]! Here's another one!

- Look at this! - You got another one?

[Chad] There's three!

-[Eric] Oh, my God. This one's even bigger! -[Chad] Three within 50 feet!

- [Eric] The same form! - [Chad] Yeah, this one's even bigger!

- Wow, this is great, man! - [Eric] This is crazy!

-We have four smelters in this little area, -Yeah, and...

[Eric] ...bats that flew out of a cave.

The cave opening has gotta be somewhere right in here.

[Chad] Hell, yeah. We are close.

[Eric] Let's continue working our way down

[Chad] We gotta find that tonight, man.

Yeah, this could lead to something, maybe.

Yeah, that... That drops off pretty good, right here.

[Eric] Okay.

- [bleep]! - [Chad] You all right?

[Eric] Damn. [bleep]!

- [Chad] You okay, Eric? - Yeah, yeah.

I don't know, Chad.

I can barely even see at this point.

[Chad] Damn! I would've thought we'd found it by now.

[Eric] I know, I know, me too.

Well, it's getting kind of late,

and I don't think we're doing ourselves any favors by

hiking around in the middle of a...

Argh!

We're close, but yeah,

we're about at the furthest reaches of the...

of the ranch here.

[Chad] Yeah, there's no cell service out here at all.

- [Eric] No. - [Chad] We gotta get back.

[Eric] I kind of lost what direction we're going in.

[Chad] Wow.

[Eric] Well, this is kind of weird.

[Chad] What is it?

[Eric] I've never seen my compass act like this.

What's it doing?

[Eric] It's not acting right.

Look at that. It's flickering.

That's weird. What could cause that, huh?

[Eric] Yeah. It's the magnetics.

If you're around a big metallic object,

like a car, or a truck, or something like that...

- [Chad] Yeah. - it will deflect the needle.

But I don't... I don't ever see it, you know,

oscillating like that.

[Chad] Right. Right, right, right.

[Eric] Something's causing this to go crazy here.

We know we have metal in the area.

- [Chad] Yeah. - There's evidence of smelting in here.

- [Chad] Gotcha. - And so, maybe it's picking up the metal

that's in the cavern.

We're also not that far away from the spot

where Duane and I got a hit on the gravity meter.

- Is there an anomaly here? - [Chad] Right.

[Eric] Is there something large and metallic underground?

That's weird.

[Charlie] You need a little help, buddy?

[chuckling] Yeah! Yeah, I sure do.

Son of a bitch is kinda tall!

So, last night, Chad and Eric

found a bunch of old smelter way back on the property...

- Watch out! - [chuckles]

[Duane] ...which means that there could be

a mine shaft or an old caver somewhere close.

Well, Eric used radiation and a gravity test

to find out where there might be a cavern.

He wants to do a few more tests

to pinpoint the exact location.

You know, when you get to my age,

patience is really not a virtue, anymore.

The feeling in my gut's telling me

that Eric's narrowed it down enough,

and I want to get this show on the road.

So I pulled the trigger, and brought in another rat hole rig.

The spot we're looking to drill

is a real remote spot on the ranch.

You know, we've never had equipment like this

out on this location.

This is not gonna be easy, but nothing's easy

when you're doing what we're doing.

[over radio] Careful going down that hill.

[operator] All right.

[Duane] Whoa, whoa! Slow down.

[Chad] God damn!

I mean, I get up this morning,

and my dad's got a freaking.

The rat hole rig, rolling down the mountain.

I know my dad's been patien my whole life,

but to be honest, I think it's a waste of mone

Me and Eric found the smelters

where all the bats and everything were,

so I think we need to go back over there,

and look for more of, like, a natural entrance.

And I know Eric has more tes he wants to run

to pinpoint the exact drilling spot.

We're all trying to figure this out,

and there's a lot of cooks in the kitchen right now.

[Eric] I just hope we can get down to that cave.

Duane's hell-bent on gettin into this cavern,

but, to be honest, I think he's jumping the gun

At this point, I only have a rough idea

of where this cave could be

Yeah, I mean, it's somewhere right in here,

but if we're off just a few feet,

we're not gonna find it.

[Chad] Here we go. Here we go.

[Duane] How're we looking?

[Eric] So far, so good, Duane.

We're chewing through it pretty good.

Yeah, it looks like it. It sure does.

So, what are we at now?

How deep?

[Eric] I'm checking samples as we drill,

to test for calcite and limestone.

This is hydrochloric.

That's what we found when we drilled on top of the box,

so if we drill here and find the same thing,

hopefully, we find the cave.

It's not reactive to acid, so it's not calcareous.

It's basically windblown sand, is what it is.

- Oh it is? - [Eric] Yeah.

So far, I'm not seeing any of that stuff here.

[Duane] [bleep]

[Mike] I'm in.

[Duane] How's it looking, boys?

[Eric] Still nothing.

[Duane] How deep, Eric?

[Eric] We're at about 80-something feet.

We'll keep going, but, um,

this is the point where we'll have to consider that we may have missed it.

[Duane] [bleep], fellas.

Okay. All right.

I agree.

[bleep] go wild, man.

Son of a bitch.

[Eric] We know from my analysis that we're in the right general area.

We may have missed that cave by a few feet

or a couple hundred feet.

I'm not sure at this point.

But I am confident that I can find the exact spot with a few more geophysical tests.

[Duane] Hey, Mike...

let's shut this deal down tonight.

[Mike] All right.

[Duane] You know, this is not an exact science

I've pulled the trigger on this a little early.

And I lost.

That might be my bad on that deal.

[Eric] Oh, that's okay.

[Duane] So, I'm gonna let Eric do his thing.

And I trust he'll put us right on the money.

Good job, Ian.

- Good job. - [Ian] Thank you.

[Chad] That's the thing with my Dad,

I mean, sometimes he just kinda gets ahead of himself.

This was an expensive mistake.

[Jamie] Where is this place?

The past couple of weeks has been pretty wild here.

We've had trespassers,

spy cams,

helicopters,

and equipment ransacked.

This has got to be it.

So I came out to talk to this guy who I heard use to work at Skinwalker Ranch

Which isn't very far from Blind Frog.

[crickets chirping]

[car door shutting]

[knocks on door]

[door opening]

Hey, I'm Jamie, I gave you a call.

I didn't exactly tell him I had a film crew following me.

But he agreed that, if I blurred his face and hid his identity,

that he would talk.

Thanks for meeting me.

[Man] So, what do you wanna know?

[Jamie] A contact of mine told me that you worked at Skinwalker Ranch.

[Man] For about 6 years.

[Jamie] Have you ever heard of Blind Frog Ranch?

[Man] I'm aware.

[Jamie] So, the thing is, we've been having some issues.

Seems like someone's keeping tabs on the ranch.

We have choppers flying over

Cameras.

Vandalism.

Ever experienced anything like that?

[man chuckles]

That's a kind of a funny question.

We were being watched the whole time.

[Jamie] By who?

[Man] No idea.

See, I used to be, uh, military intelligence.

Skinwalker brought me in to look into

what they called the "Gravity Anomaly" on the property.

Specifically, how it affected computers and machinery.

Then they, uh, started having us go look at, uh...

well, off-site. We were basically ordered to sneak onto neighboring properties.

Trespassing and, uh, do some tests there.

[Jamie] Did you go to Blind Frog?

[Man] Um, in 6 years, I'm sure I did, yeah.

I mean, we went a lot of places and...

You know, what started happening was then sometimes we'd go somewhere,

when I'd come back, someone had broken into my trailer.

Gone through my files, taken stuff, just thrown [bleep] all around.

And then the debriefs started getting weirder.

[Jamie] How so?

[Man] Well, instead of asking me about the actual tests I had done,

or data I'd collected,

they were asking about my experience.

Physiological reactions, they were taking my blood, doing EKGs, CAT scans.

[Jamie] Wow.

Who are they?

[Man] It wasn't the owner of the ranch.

It was some other group responsible.

But someone is very, very interested in this area.

You know, probably your ranch, too.

[Eric] As Stefan will do his survey,

- if he hits an anomaly, he'll see a big spike. - [Chad] Yeah.

[Eric] We're using the aeria drone with the radiation detector on it.

We were able to narrow our search field from about a thousand acres

to ten acres.

We're using a gravitometer, we went from about ten acre

down to about the size of a football field.

So, what we need to do now is narrow the area down even farther.

And, uh, the magnetometer's gonna help us do that.

So, yeah, Stefan,

we wanna scan this area in about 50 meters in each direction.

See if you just get any anomalies.

I mean, we were, we were working the bottom of the wash

and so, maybe, kinda focus on that.

There's a couple different arms right there and

- [Stefan] Okay. - [Eric] See what we got.

- [Stefan] I'll keep a tear on that. - [Eric] Okay.

So, this easier magnetomete is capable of detecting magnetic anomalies

under the surface of the ground.

Which can be caught either by a void in the ground.

Like a cave or a large concentration of metal.

Like a big old box full of gold.

But any hit we get means we're right on top of whatever it is.

Pretty steady.

That's pretty flat.

Not much going on in there.

[Stefan] What about, what about this area?

- [Stefan] Is there anything over here? - [Eric] Uh, let's see.

Steady.

Pretty steady.

[magnetometer squeal]

- It's dropping. Dropping, dropping. - [Chad] There he goes.

- [Eric] There's the spike. Stop. - [Charlie] Woah, woah, woah.

- [Eric] Big drop. - [Chad] Big drop. There it is.

- [Chad] Yep. Right there. - [Eric] Big drop.

-[Chad] Look at that. -[Eric] See it? Still going down.

[Stefan] Sometimes you have magnetic lows where you have these drainage areas.

[Eric] Okay.

[Stefan] I'm gonna move forward, let's see which direction this is in.

[Eric] Okay.

[magnetomer squeal]

[Eric] Drop.

[Chad] It's staying down now.

[Stefan] If I back up.

[Eric] It's coming up now.

- [Eric] Coming up. Coming up. - [Chad] Yeah, it's coming up.

[Eric] Coming up. Now it's back up to your baseline.

[magnetometer squeal]

[Eric] There we go. We're here.

There's something right across that creek bed, it looks like.

[Stefan] The values are changing.

From one moment to the next. They shouldn't be changing from one moment to the next.

- [Eric] No, no. They should be consistent. - [Stefan] Not like this.

[Eric] Yeah.

So there's an anomaly there.

[Stefan] Have me pinpoint that exact low.

- I'll put the sensor right over. - [Eric] Okay.

Drop. Drop. Drop.

[magnetizer beeping]

- Stop. - [Chad] Right there's the bottom of it.

- [Eric] Right there. - [Chad] Right there.

- [Eric] Perfect. - [Stefan] There you go.

There's your anomaly.

[Eric] Yeah.

[Charlie] That anomaly, would that indicate possibly

a, uh, an opening there? A cavern?

[Stefan] You do have a change in material

and that can have an influence on the magnetic field.

[Eric] Well, we got something there, boys.

This is exciting.

We got a big hit on that magnetometer.

Now we know there's something right below us.

The only thing that magnetometer can't tell us

is exactly how deep below surface that object is.

If it's down there 250 feet or more, we can't get down there with a drill.

So, I've gotta do one more test to find out what the exact depth is.

And if it's reachable...

we're in.

[Chad] So, a couple of night ago, me and Eric were out he

and found a couple of old smelters

and a bunch of bats that flew out of the hillside right over there.

So there has to be some kind of cave or mine, something around here.

I just have to find it.

I mean, cause we saw the bats right in that area.

There could be something up here, I don't know.

There's something, you know?

Argh, no.

I know that Eric has a lot of scientific tests and all this stuff,

but I know, I know for sure, boots on the ground, us getting out here and looking,

that's how we're gonna find it.

[exhales]

The sun's already going down, man.

I still got my light, though, so I'm gonna, I'm gonna keep looking.

These aren't optimal conditions, obviously, but...

we gotta find it hopefully tonight.

Argh.

Ah...

[exhales deeply]

What the [bleep].

God damn.

[Chad] Look at this [bleep].

It's a [bleep] bat.

See that [bleep]?

Hey, Eric.

[Eric] Yeah, Chad, what you got?

[Chad] Man, I found some gnarly [bleep].

Get over here as fast as you can. Where we did the magnetometer scan.

[Eric] All right, man. I'll be right over.

[Chad] Holy [bleep], man.

Hey, come check this out, man. You are not gonna believe this.

Look at this.

[Eric] Ugh, that's gross.

[Chad] Why does it have those spots?

[Eric] They look like lesions.

[Chad] Man.

[Eric] It doesn't look like any one thing just, like, killed it.

It looked like a disease of some sort.

I got an idea here. I'm gonna grab something from my wheeler.

- [Chad] Yeah. - [Eric] Uh...

this is strange.

[Chad] [bleep]

[Eric] I'll be right back.

[Chad] Damn.

[Eric] I know this might sound kinda weird, but...

let's give this guy a check for radioactivity.

Bats live in caves. Plain and simple.

So, seeing these weird lesions on the bat...

I started wondering if the cave that the bat came from had radiation in it.

Just like the cavern.

I'm not a veterinarian, but, you know, it's worth a shot.

[radiation monitor beeping]

- [Chad] Is that it, it's going off right now? - [Eric] It's going off, yeah.

It could be radiation.

- [Eric] Look, look, look. - [Chad] No!

- [Chad] That's what it is? Radiation? - [Eric] Oh, man. Yeah.

Yeah, I don't wanna even touch the freaking thing.

[Chad] Gosh.

[radiation monitor beeping]

[Eric] It's gross, but it's good news, actually.

It's good news.

We've got another little clue here.

This bat is definitely emitting radiation.

So I'd say the odds are pretty good that it was living in our dry cavern.

[Chad] Damn.

This, to me, is proof that there is some kind of

natural opening somewhere right around here.

We need a new plan.

Going to find the dry entrance. And find it fast.

Lights are still on, he's still awake.

Hey! Hey! Dad.

Hey.

[Duane] Hey, what's going on?

[Eric] Hey, Duane.

[Chad] Look at this.

[Duane] The hell is that?

[Chad] It's a bat. We found it out there by those smelters.

There's that canyon on the south-east side of the ranch.

[Duane] Really?

[Chad] Yeah, we found that under a bush. With those little, like...

- sores. - [Eric] It's got sores all over it.

[Duane] Look at that [bleep].

[Eric] The weirdest thing is, um,

we checked it with the Geiger counter and we had radiation emitting from the bat.

- [Duane] Really? - [Eric] Yes.

- [Duane] Wow. - [Eric] Those sores are indicative

of a long-term exposure to radiation.

[Duane] Holy cow.

[Eric] So, presumably it came from an entrance to that cave where we found radiation.

[Duane] No [bleep].

[Eric] That's, it's the weirdest thing I've ever seen.

[Duane] Let me get that map, let's roll that out.

Let's see what in the hell you're talking about here.

Damn, fellas, it's getting kinda wild here.

Here, let's roll this out, fellas.

Let's see what we got going on here.

[Eric] All right, so, the bat was found approximately...

as I recall, somewhere right in this area.

[Chad] Yeah, I'd say right in there up the curve.

[Eric] So, this is the same area, the general area that our

gravitometer, um, sort of narrowed it down a little bit further.

- [Duane] Wow. - [Eric] Yeah.

[Duane] Wow, wow, wow.

So, what do we, what are we thinking on this deal, what you wanna do?

[Chad] So, we know that came out of a natural cave.

If we just get some guys around and we all search that whole area,

we can find this entrance.

Instead of just wasting more and more days,

we can do this, we can do this tomorrow and have it done.

[Eric] Wait a minute, wait, wait, wait, what the [bleep].

That bat, yeah, it may have come out of a natural entrance,

but bats fly. And so, you know, where the hell is the entrance?

[Chad] We saw that whole, the whole flock of bats right there.

[Eric] But we could spend days, if not weeks doing that, Chad.

I need one more day.

Look, this area right here

is where we found the bat, yeah, but it's also the place where

that gravity meter survey gave us an area of about that.

And then we did the magnetometer survey,

it narrowed it down right on a spot.

Right there.

[Duane] The only thing I don't know now is the depth

and I need to know if it's reachable with a drill.

And that's what I'm hoping the seismic refraction survey will give us.

I'm just sayin' if we get a bunch of guys out there, no more money spent

we just find it and that's it.

I mean I wanna find it just as much as you guys do,

- but I mean I'm just trying to convince you. - I just feel we're

spinnin' our wheels, we're just wasting all this God damn time.

One more survey.

That's all we need, one more survey.

One more day.

-Just give me one more day with the seismic refraction -[Duane] One more day.

[Eric] And we're in.

I mean, I always told you this is a multi-step process,

when you're using scientific method, one day is all I need.

I can do it in one day, if you'll give me that.

- One more day. - Okay.

[Duane] One more day, let's do it.

And then Chad, put your team together by two days from now.

Yeah, I'll start roundin' people up just in case.

Fair enough, fair enough.

- We good? - All right, yeah, yeah, let's do it.

All right.

So between finding the bats there and the smelters around there

it's like, I know we're in the vicinity right there.

And if we were to get a few guys together we could,

we could round 'em up and we could just search everything.

Boots on the [bleep] ground, we're [bleep] there.

It's like what are we wasting our time for

with more science [bleep], we can find it tomorrow.

Appreciate it, fellows.

Yup, thank you, Duane.

Ultimately, my dad thought we should just go one more test

Eric said it's his last one

and if it doesn't work, then we're bringing people in and we're gonna find it.

I know you're enthusiastic about it but that's all I need man is just one more day.

- The pressure's on me at this point, so. - Yeah.

All right, cool man.

I guess I can see the frustration of the guys

putting up with this scientific method.

But, I know what I'm doing. I'm a professional geologist, that's what they hired me for.

And so, if this seismic refraction survey

show the cavern is shallow enough,

then we'll drill into it.

If we don't,

I'm a hero, or zero.

[Chad] It's right in here, man.

- Hey, this is Jamie's buddy, Dave Miller. - How you doing, man?

So, what do we got going on here?

Got stuff on this. Show you what we got here.

This is just down of Bottle Hollow Reservoir.

- Just right in between here and Skinwalker Ranch. Yep. - Is that right?

- Black helicopters. - [Dave] Black helicopters.

This happened right after they'd show up out here.

I'm telling you right now. Here's on the map.

And they came, four of them came right over the top where our project is

and where Chad was taking care of business down there.

And all of a sudden, they just showed up.

Duane, there's no secret here that you've caught the attention

of some very powerful people in this area.

When they out those birds up like that and they're flying over,

that costs a lot of money. These guys are going right over the top of your ranch

for a reason.

The more you guys are doing out here, the more you're discovering,

people are gonna look more and more for what's going on out here.

You think it's government, or...

They're watching you. I can, I can put money on it.

$22 million was funneled through the base in here for research.

The advanced aerospace threat identification program, AATIP,

all this stuff started right here in this valley.

So, you're sitting right in the crosshairs of all of it.

You gotta really watch your backs, guys.

I maybe a little bit paranoid, but it's for good reason.

Because I've gone through a lot of stuff in this valley.

So, I'm just trying to heed the warning to you, to both of you.

Watch what you're doing.

- So what do you think? - So, Brett,

this is the area right in here where we think we may have an underground cavern.

And so, my thinking is...

we lay the line east to west,

generally following the axis of the wash.

Okay, makes sense.

This whole exploration process of using different geo-physical tools,

and exploration techniques to, you know, you get all these little discoveries

that may add up to a big one.

We know we've got a great, big opening that we're right on top of.

We just don't know if it's accessible because of its depth.

Our final step is to bring in a seismic survey.

We kind of set in the middle somewhere and then just play out the...

- Okay. Okay. - Cable from both sides.

Let us know how we can help you. Chad and Duane are here to help.

- Let's do this deal. Awesome. - We've got plenty of muscles here.

All right.

[grunting]

So, what we're gonna do is we're gonna lay out a number of geo-foams.

In a straight line, right in the area where we have that magnetic anomaly.

We'll then set off a small charge which will simulate seismic waves.

-As these waves pass throug the rock, -[waves beeping]

the system will record their speeds.

This data is then fed into a seismic refraction software.

It'll tell us exactly what's down there and how deep.

- Yeah, yeah. - So these are the geo-foams that pick up--

Oh, so these are the geo-foams. That's correct. Good deal.

- All right. - [Duane] And this is where we'll set off the charge.

- Yep. Now we can dig the hole. - Okay.

- Like, right here? - That's the first foam, so...

That'd be okay, yeah.

- How deep do you need it? - About two feet.

[Duane] Okay.

- Is that good? - That's fine.

So now, we gotta set everything up.

So whenever you set that charge off, it's gonna give us a echo,

- and give us a read out there. - Yeah, it could show us exactly where it is.

Yeah. Good deal.

- Yeah. - That's good stuff.

[chuckles]

You know, Chad got pretty heated last night.

And I understand his impatience. Believe you me.

But Eric says this is the last testing he needs to do to find out if there's a dry cavern.

- Okay, so shell's ready to launch. [chuckles] - All right,

Good deal. Let's set off this charge.

- Yeah. - Really, this is the good part.

- Yeah! - Yeah.

Okay, so now, we got this bad boy.

Glorified shotgun. Saw...

What you do is put that right in there.

- Okay. - And then, just screw it on.

And then, just put her down in. Bury it.

- And then, let this one... - And then, yeah, exactly. Exactly.

- So, ready to go here. - All right.

- How hard do you want it? - Doesn't take much.

[both grunting]

- Ow! That was a shocker, man. - [chuckles] That was awesome.

- [chuckling] It was. Oh, yeah. - So, it's doing its thing, right?

So after this test drive here, what are we gonna have to do to get the data?

You just take the data and you run it through a...

It's called a dispersion program,

where you see how the energy moves out.

And then, I take those data and put them into a modelling program that

takes that seismic energy and determines what kind of layering

with depth you get.

[Duane] So, what are we talking? Maybe two hours or something like that?

- Okay. - Yeah, something like that.

If you've got all you need right here, let's wrap it up.

- All right. - We can do it at the cabin.

- Okay. - We might have an answer here.

-Let's do it. This is good stuff. -Good. Good, good.

All right.

[Duane] Did the field work. Brett did the seismic survey

and so, he's working up the data now.

And uh, crossing my fingers, man. I hope he gets some good information.

- What do we got here? - Well...

Not to get too into the weeds here, but, this is called a dispersion.

This whole method measures this...

energy that goes along the ground, this way, the surface ways.

Which only works through solids.

If you get into air, it usually doesn't work.

So, the density change is great from here to here.

And so, this is probably the upper stuff that, uh,

you were digging a hole into, and...

But then, at eight feet,

these velocities, maybe 1105 per second,

if that is the pressure wave velocity, that's right on the money with air.

- Oh, really? - You're saying air?

As in air in a cave.

[Duane] That's what we wanna hear, you know?

So what you're telling me right now is you think we have a target or a void?

- Could be, yes. - Okay.

And we can mark that spot where we can drop down and not miss it by?

I wouldn't think you'd miss it if these caves are of any size at all.

- That's good news. - That's awesome.

-[Chad] Right, boys. We did it. -That's really good news.

So, let's... That's what it shows.

- And we're right on top of it? - Well, if it's...

According to that line, if that's what we're seeing, we're on top of it.

[Duane] We got our dry cap.

We have the exact spot.

It took a bunch of tests to get to this point.

But the seismic, the last test we did, showed that we have a big ol' entrance

to a cave at about 80 foot below surface.

So we know exactly where to drill now.

That, that's perfect. This is good.

Hell, yeah.

This is, I think the best news we've had so far.

- This technique is valid, and... - It's pretty big, yeah.

[Duane] We were not just spinning our wheels here. We know exactly

where to put that rig and punch in.

Hopefully, into that void.

[Chad] Well, Eric was right Patience can actually be a good thing.

When we looked at the results that Brett showed us in the cavern,

and it looks like there is a void under there.

So, we're all excited.

We're gonna bring in the rat hole rig, and we're gonna

drill a hole and get in there.

- Yeah, this is good stuff. - Thank you, Brett.

- That'll be fun. No problem. - Good deal.

[Charlie] This is it.

After all that searching and testing, we finally found the new way into the cavern.

We're so close, I can taste it.

But, out here on this ranch, that's when things seem to fall apart.

So I'm not about to start celebrating yet.

You know, we got a lot of work to do before this deal's done.

[narrator] On the final two episodes of Mystery at Blind Frog Ranch...

[Chad] We are right on top o cavern, right there.

It's time to start drilling, baby.

- [Duane] Whoa! - [Chad chuckles]

- [Chad] Holy [bleep], man. - It's dry!

[Chad] Oh, this is gonna change everything.

[Dave] Hey, guys, you're gonna wanna see this.

There's three cars all around.

[Charlie] They're up to something.

[Dave] Let's go.

Whoever's been watching us is getting more aggressive.

Seems like they just keep on coming at us.

[Chad] But we have to move forward.

- Good job today, guys. - All right.

I'm real excited about getting into this cavern, but,

we detected radiation in the bottom.

- [device whirring] - Oh, boy...

And so we're gonna need to suit up.

Going down the hole. It's the closest thing to a suicide mission.

[machine creaking]

- Going down! - [machine whirring]

[breathing heavily]

[Duane] Once we start getting into that cave...

Hey! You're going off! You're blinking red!

things can change like that.

- [Chad] Oh, my God! - What's happening? It's not--

[Chad] Go, go, go, go! Get him outta there!

- [Duane] Okay, I'm on! - Go! Pull up! Pull him up!

- We gotta get Duane! - Hold in!

[indistinct]

[Eric] Go get Duane!

I'm not in here, but...
