Tonight, on "The Proof Is Out There."

Was a legendary Birdman caught on camera?

The Birdman was a supernatural deity

that was much revered.

Is an ancient alien satellite orbiting earth?

The Black Knight satellite is a UFO theory

that's been bouncing around since before the internet.

Is a behemoth crying out

from the bottom of the sea?

This is a really eerie sound

that reminds you of something a deep sea monster would make.

And does this UFO footage from Germany

help explain a mystery of World War II?

Nothing in the sky should be moving like this.

Around the globe are videos...

What are those things?

It's moving.

Photos and sounds that defy explanation.

We don't know where they come from,

who made them, or how they operate.

What are they?

Some sort of bizarre mutation.

What's exciting is nobody really knows.

Extraordinary claims need extraordinary proof.

I'm Tony Harris,

and as a journalist for more than 30 years,

I've followed the facts where they take me.

Now, I'm bringing that spirit of investigation

to the world's strangest sounds and images.

We'll analyze each one with top experts.

It's a credible case, it's a credible video.

And pass a verdict on what it is.

This video was clearly faked.

The proof starts now.

Good evening and welcome to "The Proof Is Out There."

More than 40% of homes in America

have some kind of surveillance camera.

And while the majority are installed for security reasons,

we have been able to take advantage

of another added benefit,

recordings of strange creatures in the night.

August 27th, 2017.

It's just after midnight in a quiet,

residential neighborhood near Youngstown, Ohio.

Suddenly, a motion detector camera

is triggered by a movement in the driveway.

Let's take another frightening look.

A strange creature races past a parked car,

then disappears into the night.

It appears to have a white head,

dark body, while running on two legs.

According to field researcher Ken Gerhard,

no one, including the homeowner, knew what they were seeing.

When this footage came out,

I remember it created a bit of a stir

in the cryptozoology community.

The owner claimed that this thing

was some type of bipedal, bird-like creature

with black plumage, a white beak, and very long white legs.

She estimated it was about three to five feet tall,

but what's really remarkable

is how fast this thing is moving,

about 15 feet in only two seconds.

The owner ultimately claimed

that she saw this creature multiple times

making clicking noises.

And she even claimed she found some massive piles

of what looked like bird droppings.

A birdman or bird-like creature

roaming the streets of Ohio?

It may not be as farfetched as you think.

Gerhard says this type of creature

has been part of Native American folklore for centuries.

There is something known as the Cahokia Birdman,

a carving in sandstone of an anthropomorphic,

half-man, half-bird-like creature

found in East St. Louis in 1971

and dated to be about 900 years old.

Another theory online is that

this was an escaped exotic animal like an ostrich.

Ohio has seen that before.

In 2011, a Zanesville man made national news

when he released his massive collection

of 50 animals into the wild,

including 18 tigers, 17 lions,

8 bears, and 3 cougars.

Why couldn't a renegade ostrich be running the streets?

There's apparently been no shortage of strange creatures

spotted in Ohio over the years.

The Loveland Frogman is supposedly

a four-foot-tall cryptid

that has been spotted numerous times in Loveland, Ohio

since the 1950s and even inspired a musical.

Could this alleged birdman

of Youngstown soon be heading to Broadway?

Let's check in with the experts to see what we've got here.

If it's not a Birdman, is it just a man?

Could this just be an elaborate prank?

Biologist, Stephanie Manka explains the footage.

I don't think this is a human in a costume.

It doesn't seem to have the head shape of a human.

The legs are too tall and the torso's too short.

And overall, it's small compared to the car here.

Okay, so Manka believes

we can definitely rule out the man,

but what about the bird?

It does look like a bird.

The fact that massive, bird-dropping-like things

were left behind makes sense.

Some speculated this could be a wild turkey,

with an estimated length of up to 49 inches

and droppings nearly three inches long.

There are 160-180,000 of them in Ohio.

I don't think it's a wild turkey,

because the legs look too long to be a turkey,

the head looks too thick and too light,

and the body doesn't look round enough.

However, Manka does see similarities

to another type of bird,

albeit not native to the United States.

Ostriches and emus can run fast like this,

but it's not big enough.

And then I looked into rios, which are smaller ground birds

that can run pretty fast, and I was thinking it was that.

But wildlife biologist Floyd Hayes

thinks we're looking at another kind of creature altogether.

This animal cannot be a bird.

Instead, it is a mammal.

It looks like it's running on two legs.

Possibly because of the angle from the camera

and the low resolution,

they're not really seeing the front limbs

of a four-legged animal.

But what kind of four-legged animal?

Hayes notes the coloration eliminates

typical nocturnal predators.

Foxes and coyotes and wolves

tend to be relatively uniformly colored.

In this particular animal,

it looks like we have a white-ish head,

a black-ish body, and white-ish legs.

Instead, Hayes believes this is an animal

much more likely to be roaming suburban neighborhoods at night.

To me, this looks like a medium-sized dog that's running.

We're not able to see the tail very well,

but I think I'm seeing glimpses of it

as it's moving through the video.

But Manka has her doubts.

I can't make out any of the front half of the animal.

I can't see four legs or paws or anything.

So I don't think this is a dog.

Our verdict, we're going with unidentified mammal.

Hayes's analysis convinces us this is some sort of mammal

and not a bird running through the driveway.

But exactly what kind, we're not sure.

In the meantime, we're still on the lookout

for evidence of the Loveland Frogman.

So, Ohioans, keep those cameras at the ready.

Now for one of our favorite kind of stories,

the kind you send us.

History's first satellite, Sputnik,

was launched into orbit almost 70 years ago by the USSR.

But there's a group of UFO theorists who insist

there's a satellite up there that's older.

In fact, ancient.

And one hardcore proof fan thinks he caught it on camera.

It's November 2018.

Nicos Vouris is walking with his daughter Nika

along the beach in Cape Town, South Africa.

Around 7:00 PM, Nika spies something strange in the air,

something that may have been watching us for centuries.

This is a UFO of some sort.

Look closely.

A strange, malleable, black shape hovers high above Nicos

and his family.

It seems to float without obvious direction,

silently, holding position.

We thought, "Okay, this can't be like a normal drone."

And it's just hovering there.

It did weird, wonderful maneuvers like that,

like by going vertically,

then horizontal, then vertical again.

It was just amazing to see.

But while many, at first sight,

would think this is a drone or possibly a spy balloon,

Nicos believes it's something much more extraordinary.

I'm an untrained observer.

But in terms of what I saw,

it was very much reminiscent of the Black Knight satellite.

What is the Black Knight satellite?

Writer Amy Tietel explains.

The Black Knight satellite is a UFO theory

that's been bouncing around since before the internet.

Believers say the satellite

is an alien surveillance and communication device

that has been in a polar orbit for thousands of years,

inserting itself into human history when it sees fit.

Some people have even gone so far

as to say that this satellite

is what Nikola Tesla was communicating with

during his radio experiments in Colorado Springs in 1899.

He heard some kind of frequency

and some people believe

that he was actually speaking to the Black Knight satellite

and it was communicating with him through math,

using numbers as the universal language.

For years, this remained

a science fiction theory that was kind of cool, kind of scary,

but still just a theory,

until a strange object was spotted

about 200 miles above the Earth.

In 1998, during the STS-88 mission,

astronauts photographed something

hovering above the Earth's horizon line.

And this became a big mystery.

Some people have used this photograph

as definitive proof that there are aliens

interacting with our planet.

For many, what makes the Black Knight satellite

so compelling is the logic behind it.

If an alien race wanted to study the Earth,

why wouldn't they send a probe?

The same way NASA sent Voyager I

to explore other planets in our solar system.

So what is this thing?

ET satellite, balloon, or something else?

Astrophotographer Andrew McCarthy

is a Black Knight skeptic.

He says the most famous piece of evidence,

that 1998 NASA photo, was more a visual trick

than proof of alien spacecraft.

It's outside of the window of the space shuttle

that was not in direct sunlight

so appears dark against the bright contrast of the Earth

and the surrounding space.

Seems to be just a normal piece of space debris.

Astronaut Jerry Ross,

who took part in the STS-88 mission,

confirms the object from the 1998 photo

is a wayward thermal blanket that broke loose

while his team tried to attach an American module

to a Russian module on the ISS.

But just because the 1998 picture can be debunked,

we still have to ask,

could Nicos's footage be of a genuine alien satellite?

We take that question to video analyst Mick West.

I don't think this is a satellite.

We simply wouldn't be able to see a satellite

at that distance.

But the closest satellites from Earth

are about 200 miles up.

The International Space Station

is the largest satellite that's up there,

and you can only really see that as a dot of light

and you can't see it at all during the daytime.

Could the object Nicos captured be a spy balloon?

It could be a spy balloon.

Typically, a spy balloon

would have something dangling underneath it,

but it could be a type of spy balloon where the the payload

is actually attached to the balloon itself.

In February 2023,

US military jets shot down a suspected Chinese spy balloon.

The 200-foot tall balloon had multiple antennas

and a solar array that government officials say

was capable of capturing imagery and signals

from military sites

and sending them back to China in real time.

Did Nicos see one over South Africa?

McCarthy has his doubts.

This object doesn't fit the profile of a spy balloon

because it's way too obvious.

Those balloons are much higher altitude

and usually white to blend in with the sky

and to reflect the sun's energy back out and not overheat.

So if it's not spying on us,

could it be another type of balloon?

A solar balloon is a type of hot air balloon

which uses the heat of the sun to warm up a balloon.

And they do that by making the balloon out of black plastic.

Because black absorbs heat,

the air trapped in the balloon expands, creating lift.

But I think we can rule that out

because the shape of this object

would be consistent if it was,

as as the air heats,

the material around it becomes taut

and can no longer change its shape.

So while it might not be

a functioning, inflated solar balloon,

couldn't Nicos's Black Knight satellite

simply be a deflated balloon

or even airborne trash caught in the air currents?

Pilots are always seeing things like balloons

or wind blown debris, things like plastic bags.

This is one of the big problems the UAP Task Force had,

which was dealing with airborne clutter.

Our verdict, a trash bag or balloon

caught in air currents.

Sorry, Nicos.

This might not be the sexiest answer,

but because of its size, movement,

and through process of elimination,

that's what we have to conclude.

Germany has its own history of UFOs

going back at least as far as World War II.

This next puzzling footage

is a much more recent sighting out of Deutschland.

And whatever it is,

we know it's not one of the 99 luftballons.

September 29th, 2014.

It's a beautiful day in Berau, Germany,

a rural southern village near the Swiss border.

A photographer sets up his camera

to film the perfect sunset.

But when he watches the footage back,

he has captured something else entirely.

A bright, streaking orb jetting across the sky.

Suddenly, the object seems to zigzag violently

before continuing downward.

Let's see that again.

Journalist Eric Grundhauser is intrigued by that hard turn.

The way that it moves,

it doesn't look like the behavior

that any earthly vessel could possibly undertake.

Much of the online speculation

centers on the location of a sighting,

a place considered by some to be the birthplace

of the modern UFO phenomenon.

It was 1944, behind German lines,

the elite 415 Night Fighter Squadron reported

strange phenomena in the skies over Germany.

The incident involved a Bristol Beaufighter crew

led by pilot Edward Schlueter and his crew mates

who were flying over the Rhine Valley near Strasbourg.

The crew described 8 to 10 orange orbs

flying at high speeds off of their left wing.

The lights appeared from nowhere

moving at erratic angles, dancing around the planes.

The puzzled squadron could not shoot them down.

They also never appeared on radar.

The pilots dubbed the bright light bogies,

allegedly captured in this photo, "foo fighters."

Since the foo fighters caused no damage,

the American crewmen doubted

that they were actually German secret weapons.

German pilots claim to have seen foo fighters as well,

and they were just as baffled.

But there are other modern instances

of similar bright orbs descending on planes too.

On a previous episode,

we analyzed this 2020 sighting from the Mexican skies

where veteran military

and commercial pilot, Captain Eric Delgado,

recorded this footage.

Oh man, that is phenomenal.

And you saw it dropped out of the sky

and just stop?

The UFO paced Delgado's plane

before shooting off at a sharp angle,

generating G-forces no human could withstand.

It's the kind of inexplicable maneuver

we've come to associate with UFOs, from foo fighters

to those encountered more recently by Navy pilots,

to this very video.

Both the foo fighters legend

and the modern footage shot by Captain Delgado

remain mysteries.

How will this German orb footage

hold up to our experts' scrutiny?

Time for our team to dig in and find out.

Is it possible all these highly maneuverable UFOs

are a single type of craft and this is one of them?

First, physicist Matthew Szydagis

dissects the motion of the object.

It does seem to be going extremely fast

and also at one point, executes a remarkable turn.

That single hairpin turn

might match foo fighter reports,

but Szydagis is quick to point out

the object doesn't repeat the impressive move

the way alleged foo fighters did.

The object appears to move in a straight line.

It doesn't do anything particularly spectacular.

Foo fighters were known to track aircraft

and I don't see this ball or circle tracking any aircraft.

So, I don't think that this is a foo fighter.

So if it's not a foo fighter, could it be a meteor?

Szydagis says timing is everything.

This is a time-lapse video,

which means that we're looking at the sun

setting over a long period of time.

If that's the case,

this is way too slow, actually, to be a meteor.

Most meteors are visible for seconds,

burning up in a flash.

So the revelation that this is a time-lapse video

rules that out altogether.

The skip in time from the time-lapse

could also explain the erratic movement.

So, it's not a meteor or an alien spacecraft.

Could it be a non-alien spacecraft like a satellite?

This could not be a satellite

because it's still way too bright

to see even the brightest satellites.

Satellites do come out at sunset,

but only after the sun goes down.

Instead, astronomer Marc D'Antonio

thinks the object is something inside the camera.

Here's the thing with cameras,

whenever you point them into the sun,

you're gonna get things you don't expect or don't want

because the sun is immensely brighter

than anything else in the field of view.

So if this is something up in the sky,

as soon as it starts to go down toward the horizon,

it should slow down.

To your eye, it's not.

It stays the exact same speed.

That tells me that it's probably a camera artifact of some kind.

Our verdict, lens flare,

or another kind of camera artifact.

We wish we could say this video

brought us closer to an answer on the foo fighter legend,

but not this time.

Those mysteries continue.

Now, we go from the air to the ocean.

On this show, we love nothing more

than a good, deep sea mystery,

especially when there's a very large creature involved.

And this next video is so mind-bending,

it would have Jules Verne himself saying,

"Come on, Monsieur."

2017, the Mediterranean Sea.

A team working a debris sweep along ocean pipelines

comes across what at first

looks like just another deep sea carcass to be cleared away.

But closer inspection reveals this is truly something unusual.

What appears to be a 90-foot-long, dusty spine

sits undisturbed on the bottom of the ocean.

A remote controlled crane reaches out

to investigate the skeleton,

turning over one of the vertebrae, which disintegrates.

British podcaster and investigator Debbie Hatswell

was one of the first people to see this intriguing film

after a member of the pipeline maintenance team

reached out to her.

He said, "I've seen a lot of carcasses on the sea floor.

And I've seen whale carcasses and all fish and all that,

and it just doesn't fit.

It doesn't fit with what they are."

He's saying this is an anomaly.

And he's felt that it was a very, very old animal

of some kind.

So I reached out to a number of marine biologists,

and nobody really got back to me with it as to what it was.

Field researcher Ken Gerhard

explores the idea that perhaps these are the remains

of a long extinct ocean predator, the dreaded megalodon.

In 2022, the Atlantic Shark Institute out of Rhode Island

was deploying sonar

when they encountered what they believed to be a shark

of unbelievable proportions.

Perhaps 50 to 60 feet in length.

Now, if so, this would be the best account

of a modern megalodon.

The megalodon,

a nautical nightmare that experts believe

could weigh as much as 50 tons,

has been thought extinct for nearly 3 million years.

Have these Rhode Island researchers

uncovered a modern day version of this historical monster?

And if so, could we be looking

at the remnants of one in this video?

This would certainly fit within the paradigm

of what we know about megalodon.

Gerhard also sees a connection

between this discovery

and the classic mythology of the region.

In Greek mythology, different sea monsters

like Cetus, Charybdis, the Lernaean Hydra,

were said to live throughout the Mediterranean Sea.

And while there are many suspects,

there's one sea dragon sighting in particular

that Gerhard thinks could be connected.

In October 1907, fishermen on the island of Corsica

claimed that they were terrorized

by a horrible, 200-foot sea dragon

that actually ripped apart their nets.

And the fishermen were so scared to go back out and fish

that they actually called on the government

to bring in a torpedo boat in order to kill the monster.

And that just happens to be the location

where we've got this footage of a 90-foot spinal column.

Sea dragons can be found

in all sorts of ancient texts and tales

dating back thousands of years.

From Norse mythology's Midgard serpent

to the ancient Babylonian's saltwater dragon Tiamat,

who many say was rebranded

as the Leviathan in the Old Testament,

is there a connection here?

Let's see if our experts can help slay this oceanic mystery.

Marine biologist Dr. Shea Steingass strongly doubts

these are the remains of a sea dragon of ancient myth.

It's been hypothesized that this might be a sea dragon.

That's probably not the case

'cause we really don't have any scientific evidence

of these creatures existing.

Steingass also points to the fact

that we can see what appears to be a pelvis,

something not found in the numerous depictions

of these serpent-like creatures.

What we're actually seeing here

is a very old skeleton of some kind of modern animal.

But the only documented modern marine animal

that could possibly grow to this length would be a whale.

Could that be what this is?

I would say the chances that this

is a really large whale skeleton are really slim

because we would likely see other types of large bones

like a skull, if we were to see a spinal column.

These remains aren't like anything

I've really seen before.

With Dr. Steingass at a loss,

we checked with wildlife biologist Stephanie Manka

to see if this could be a modern megalodon

like the one thought to be discovered near Rhode Island.

If it were a megalodon,

I wouldn't expect to see the bone as intact as this.

Megalodons, like other sharks, instead of bone skeletons,

they have cartilage skeletons which don't fossilize well.

Bone contains minerals, whereas cartilage doesn't.

Bones are much harder.

And if you think about your ear,

this part where it bends, is the cartilage,

and that's what shark's skeletons are made of.

When cartilage breaks down,

it turns into a jelly-like substance

that dissolves into the water,

which is why the only proof we have for megalodons

are their teeth.

And as for that alleged megalodon spotted

by the Atlantic Shark Institute of Rhode Island,

further research indicates this sonar image

is more likely a large school of Atlantic mackerel.

So with all of our theories ruled out,

what is Manka's best guess?

I believe that this is a whale.

What is probably going on here is the whale skeleton

has been on the ocean floor for so long

that organisms have eaten away at the bone

and there are fin whales in the Mediterranean,

which are the second largest whale species.

They usually don't get up to 30 meters,

so there is a little size discrepancy,

but everything else seems to elude that it is a whale.

Our verdict, unknown sea beast.

Stephanie Manka thinks it could be

an abnormally large whale,

but our marine biologist, Dr. Steingass, says no way.

Until there is further investigation

of the skeleton itself beyond this video evidence,

these bones will remain a mystery.

Imagine you're in the open ocean.

Visibility is good and there's nothing to see for miles.

Then, out of nowhere, you hear a massive, guttural cry

like some giant sea monster

waking from a centuries-long slumber.

Scary, right?

Well, take a listen to our next story.

It's March 1st, 1999,

and the National Oceanic and Atmospheric Administration,

or NOAA, is continuing its deep sea research

along the frozen waters of Antarctica.

As they record audio of the water

using an autonomous hydrophone array,

an unexpected sound emerges.

We hear a strange, otherworldly moaning sound

emanating from the bowels of the deep.

If some sea beast is making this noise, it has to be huge.

The sound is loud enough to be heard

over a range of 3,000 miles,

but where it's coming from exactly, no one knows.

Journalist Erin McCarthy says experts

were confounded by this underwater roar.

It's believed to have originated

between the Bransfield Straits and Cape Adare in Antarctica.

The National Oceanic and Atmospheric Administration

nicknamed this seriously loud noise the "Julia" sound.

The Antarctic is home to plenty of wildlife,

so one theory is that maybe a known creature

created this loud sound.

In fact, the Antarctic waters are home

to the largest and loudest documented animal in the world,

the Atlantic blue whale.

Weighing more than half a million pounds,

the blue whale calls can be heard for hundreds of miles

and can reach decibels louder than a jet engine.

But according to Erin McCarthy,

theories began to emerge that the sound was made

by something more monstrous.

Some have wondered if the Julia noise

is actually the sea monster, possibly the Kraken.

The Kraken,

one of the most legendary monsters of the deep,

was a giant, multi-tentacled, squid-like creature

that dominated the nightmares of sea folk

since the 12th century.

And while many consider the Kraken

to be nothing more than a myth,

recent discoveries of ichthyosaur dinosaur bones,

some found right here in Antarctica,

suggest something killed these 30-foot marine beasts

by crushing their chests and twisting their necks

by using large tentacles.

Could this be a Kraken?

Cape Adare is the site

of the first documented landing on Antarctica.

Norwegian explorers arrived there in 1895

and later built two huts there,

the first known human structures erected on the continent.

More than a hundred years later,

what could be causing the mysterious sounds

emanating from the depths of the continent's remote waters?

Marine biologist Shea Steingass vetoes the Kraken theory.

The Kraken, which is an incredibly large,

squid-like sea monster,

wouldn't even have the right organs or anatomy

to make these sounds.

Squids are just cephalopods.

Cephalopods don't even really have vocal cords and lungs,

because they're actually just ocean dwelling invertebrates.

While all marine mammals

can communicate with sound,

as can certain fish and even loud clicking crustaceans,

cephalopods remain stealthily silent.

So there's nothing on a Kraken or squid or octopus

that can even make this kind of a sound.

In any case,

we checked with forensic sound expert Rob Maher,

who first tests the Julia sound against the blue whale.

Comparing the frequency range of the the blue whale

to the Julia sound,

the blue whale is at a lower frequency

than the Julia sound.

The characteristics of a biological sound underwater

don't match what we would see in the Julia sound.

Maher also rules out mechanical sounds

like deep sea drills,

since those tend to be regular and rhythmic.

This thing sure isn't.

So what does that leave us?

Maher thinks there's only one remaining possibility

that makes sense.

It's likely from geological sources.

We also have ice and glaciers that are entering the ocean.

And the motion of the ice rubbing against other ice,

or against the ground, or the ocean surface,

will create sound.

Icebergs make sounds?

Turns out, we only discovered that in the past 25 years.

In fact, these sounds are some of the loudest in the ocean.

The equivalent of 200 super tankers

on par with undersea volcanoes and earthquakes,

and can be picked up thousands of kilometers away.

If we compare this sound shown here

of an actual iceberg event...

The characteristics of this tone

are similar to what we see in the Julia sound.

Our verdict, icebergs.

Such a massive sound like Julia

requires a massive force behind it.

And in Antarctica, nothing comes bigger.

As for our Kraken,

he will just have to stay dormant for now.

On this show,

we've told you about rocks that grow, rocks that sail,

and even rocks that look like encrypted alien messages.

But have you ever heard of rocks that sing?

Well, you're about to.

It's July 2020, outside Butte, Montana.

Photographer Nickolas Warner has traveled to Dry Mountain

to witness one of the strangest natural wonders

in Big Sky Country.

His drone footage shows a massive pile

of rust-colored boulders

that seem oddly out of place in contrast

with the drab gray of the rocks lying nearby.

And when struck lightly with a hammer...

Each boulder produces a bell like tone.

Some rocks, depending on where you hit them,

they come up with a different sound.

I'm still kind of baffled

by how it was able to make such a loud,

distinct ringing sound.

For whatever reason, this specific pile of rocks

has some sort of strange quality to it.

What's especially strange

is that when rocks have been removed from this site,

they no longer ring.

Nickolas says the whole area

has a kind of creepy feeling to it.

It was that feeling where someone is watching you.

It felt very uncanny.

I would say that there's definitely

some sort of mystical qualities to the area.

The bell rocks of Montana

aren't the only ancient stones

to produce this unique brand of rock music.

Many civilizations believe these areas,

where rocks ring like they are hollow,

were special places of great mystical

and spiritual significance.

Ringing rocks and gongs of various types

and with differing sounds are found around the world

at sites in the US, Mexico,

Europe, Africa, India, and Australia.

But where did these massive,

seemingly out of place stones come from?

Author Jason Martell says some think

sound helped build the Egyptian pyramids

and maybe move these rocks as well

Around the world,

there's theories that using vibrational sound

can actually levitate large stones.

I think that perhaps they were moved here

using some type of a sound frequency.

Experiments have proven it's possible

to levitate objects by using high frequency sound waves

to create a standing wave

that acts as a force to counteract gravity.

But can it work for something as big as boulders?

There may be several sites around the world

known for their ringing rocks,

but there has been less investigation

into the special property of these stones

than you would expect,

especially considering that humans have used them

as musical and ritualistic instruments

since before written history.

So what's going on here?

Our experts leave no stone unturned.

We take the footage

to our forensic audio analyst Dr. Rob Maher

and deduce if the rocks were put here intentionally.

First, he compares them to church bells.

The ringing rock have this characteristic here,

which is loud and then it dies out as the ring goes away.

And for the church bells here...

We can see the same characteristic of the sound.

We can see the start of that, and then the decay.

So the two sounds are distinctive.

Our ear can tell the difference,

but they share many of the same kind of characteristics.

So maybe these rocks were placed here on purpose

to designate a spot as sacred as a church?

But while the bell rocks share similar properties

with a church bell, Maher says

they don't show signs of being intentionally arranged.

The orchestral chimes will ring

for a much longer period of time.

They're designed very specifically

to give that sustained sort of quality

so that they will have a longer duration of vibration

and give us a different sound quality

than the random collection of minerals in that rock.

So if nobody put these ringing rocks here,

where'd they come from and why do they ring?

NASA geologist Dr. Bob Anderson weighs in.

It looks like a pile of rocks that somebody

might have dropped off, it's not.

What it is, it's an old, what we call a plug or a batholith

from a volcano that has been exposed

and is breaking apart into all these pieces

because of weathering.

A batholith is a large mass

of intrusive igneous rock,

which forms from magma that's cooled

after rising into the Earth's crust.

Perhaps the most famous batholith

is Half Dome in Yosemite National Park.

Anderson says the secret behind the ringing

is most likely a combination

of the mineral composition of the rocks

and the way joining patterns have developed

as the rocks have eroded.

That's why they only ring here.

The resonance depends on how they are connected.

Most of these rocks are basalts,

And basalts are igneous rocks

that come up from the underground.

What happens over the years, the rocks are breaking apart.

Each of those rocks, as long as they're in connection,

has that resonant standing wave that'll ring as a unit.

But when you start seeing all these little pieces,

now you're making up the orchestra.

And so all the little pieces

have a different pitch and different tone

as they break apart and weather away.

Our verdict, this is a natural geological phenomenon.

But we still can't explain why people feel

a mystical presence around the ringing rocks.

If you make the trip out there, maybe you'll feel it too.

Just make sure you leave the rocks as you find them.

In an earlier episode,

we brought you a story of a ghoulish,

unidentified creature that left us baffled.

But thanks to our loyal viewers, new information has emerged

that may help us solve this rather grotesque puzzle.

While it remains uncertain where this footage was taken,

the story supposedly first unfolded

in a small village in Russia.

We're told a local farmer alleges

that his home has been shaken by a large explosion nearby.

While looking for the source,

the farmer stumbles upon this.

Some remains that look nothing like the usual local wildlife.

Take a good look.

The creature has a strange head

and an even stranger torso and limbs,

and the state it's in is even more puzzling.

It appears petrified.

According to the source who gave us this video,

the cause of the explosion was never found

but residents of the town were more frightened

by what this creature could portend for their village.

In our first go around,

journalist Erin McCarthy suggests

that the answer may tie back to climate change.

Permafrost is melting in Russia

and with that melting,

all kinds of extinct creatures are popping up

like mammoths and rhinos.

Melting permafrost has revealed a plethora

of long forgotten life forms,

from a 3,500-year-old mummified bear

to potentially deadly ancient viruses.

In fact, many think a deer carcass thawed in Siberia

caused an anthrax outbreak throughout a remote village.

Could this creature be the latest reveal

from the permafrost?

We turn to our resident biologist, Dr. Floyd Hayes.

It's possible that this is an extinct species of animal

that formerly lived in Russia that is no longer there today.

Our experts were stumped when they first saw this clip.

But after running this piece,

we got word from our most important armchair experts:

You.

And that changed everything.

After our first story aired,

Joyce Driscoll, one of our eagle-eyed viewers,

reached out to share some much needed intel.

The first time I saw that episode,

I said, "I know what that is."

I remembered this shop called The Witch's Shop in Bolivia.

One of these things was hanging from the ceiling.

It was a llama fetus.

Wait a second, a llama fetus?

And from Bolivia, not Russia?

They look exactly like that

because they're actually hung by cords

at the back of the neck,

just like the one in your show is,

and they're hanging all over that shop.

The things in there were used for good luck

or, you know, good harvest, bring rain,

traditional, native-type stuff for the the local people.

I don't know how a llama fetus could do all that,

but that's what they said.

We checked back with Floyd Hayes

about this surprising revelation.

And after this second glance, he concurred with our viewer.

As it turns out, the creature was a llama fetus.

Llamas, they're preserved and kept by Bolivians.

But Hayes feels no shame in being corrected

by one of our audience members.

I was pleased to learn

that the true identity of the animal

was provided by a viewer of the show.

As for our viewer Joyce,

the respect is more than mutual.

I did not mean to one-up your experts.

They do a fantastic job on your show

and that's one of the reasons I watch it,

because I like that expert opinion.

Our new verdict, llama fetus.

Our intrepid viewers may have solved this one

and raised serious doubts

about where this footage came from.

Russia? I don't know.

Bolivia seems much more likely.

This much we do know,

we couldn't have explained this story without your help.

And that's our show for tonight.

If you have any tips for us, we'd love to hear from you.

So drop us a line and keep those cameras rolling.
