Temperatures In a steam train firebox

That can tear through Skin and muscle.

Yannotti: miss attitude. Bears can be very aggressive.

Black bears can kill people Easily, easily.

Narrator: since the year 2000,

There have been 48 fatal Bear attacks in north america,

Whereas sharks have only killed 15 people in the us

During the same period.

The black bear's natural habitat Is rapidly shrinking,

Driving these large animals Into our towns and cities

In search of food,

Where confrontations with humans Are becoming evermore frequent.

In 2014, 22-year-old hiker Darsh patel

Encountered a black bear In new jersey.

Incredibly, he took Multiple photos of his killer

Moments before It mauled him to death.

[ growls ]

Could the clovis footage Have captured a black bear

Foraging perilously close To the family in the house?

What's in the footage is walking On two feet, very confidently.

When these guys get up On their hind legs,

They're very stiff walking, And they don't move,

Like, fluidly, like the image On the screen does.

I would say that rules out A black bear.

Narrator: Physicist john di bartolo

Notices something in the footage

That reminds him of a phenomenon Caused by light beams at night.

Di bartolo: Every one in a while,

when you're driving Down the road

and you see two beady eyes Staring back at you

Of a cat or some animal, Then that is light

That's being reflected Right back where it came from.

That's why we see just The eyes so brightly.

Narrator: Di bartolo's best guess

Is that a similar phenomenon Might explain

The apparition In the security footage.

It's possible The mysterious glow

Is because this person Was wearing reflective material.

Narrator: Just like glowing animal eyes,

Reflective materials Worn by humans

Are designed To bounce light back

In the direction of its source.

We notice this disembodied torso Only because it's so bright

Due to the reflective gear.

In contrast, the head,

The hands, and the legs Of this person's body are so dim

That they're essentially ignored By the security camera,

So we simply don't see 'em.

God help anyone that is sucked Into that vortex.

This is not just dangerous. It's downright deadly.

Narrator: latvia, Located in eastern europe

On the border of russia,

Is a land With a brutal history.

First, crusaders arrived

To put the pagan population To the sword.

More recently, it has seen Bloody invasions

By communists and nazis.

Later decades have seen A respite from terror...

Until april 2013.

A traveler films As an aquatic mouth opens,

Swallowing huge chunks Of ice whole.

It's basically the water Equivalent of a black hole.

All these things are going in, And nothing is coming out.

That whirlpool could suck you Into a watery grave.

Narrator: travelers in latvia Stumble across a raging vortex

That is devouring Everything in its wake.

The footage is sent

To extreme weather expert George kourounis.

He believes this could be

An incredibly dangerous Natural phenomenon.

We're looking at some type Of a whirlpool here,

and a whirlpool is basically A rotating vortex of water.

Narrator: these are some Of the most destructive forces

In nature.

There's giant chunks of ice that Are literally just disappearing,

Being inhaled by this whirlpool.

Narrator: by analyzing

The size of the phenomenon In the footage,

Experts categorize it As a maelstrom.

maelstrom means Giant swirling vortex of water.

The force gets stronger The close you are to the vortex.

The power would become More and more overwhelming

Until you reach That point of no return,

And you get sucked down, Basically, to a watery grave.

Narrator: could latvia Now be home

To a new fearsome maelstrom?

Searching for information On these giant whirlpools,

Journalist jeff wise Uncovers details

Of the world's largest Active maelstrom.

the biggest whirlpool In the world is called

the maelstrom of saltstraumen, And it's in norway.

Narrator: kourounis believes The same forces at work

In the saltstraumen maelstrom

Could be what's powering Latvia's giant vortex.

The norwegian whirlpool Is caused

By conflicting forces of The tide coming in and leaving,

So those opposing forces meet,

And where they meet, The water rotates.

Narrator: the huge energies of The tide power the whirlpool,

Making it Larger and supercharged.

But when wise checks where This maelstrom is captured,

He discovers a crucial detail

That makes a tidal-powered Vortex seemingly impossible.

This is filmed over 100 miles From the latvian coast.

Wise: this isn't Taking place in the ocean.

No, this is taking place In a river.

Rivers aren't a product of tides

In the way that The currents in the ocean are.

Geoscientist sian proctor Examines the footage.

She believes there could be A geological process

Powering This monstrous whirlpool.

It's kind of like someone Pulled a plug

At the bottom Of this lake or river,

And it's all being drained Into it.

So the question is,

What's happening underground At that location?

What I think is happening Is that maybe it's a sinkhole.

Think of a cave underground That suddenly collapses in.

Narrator: analyzing The strength of this vortex,

It makes proctor fear a void Could be growing beneath latvia.

If I was walking along The shore, I'd be thinking,

"Is there any danger Of it getting bigger?"

If you were to fall into This location

And got sucked down, You're not coming back up.

Narrator: a check Of local geological records

Reveals no evidence

Of naturally occurring Underground voids

Anywhere in this region.

The footage is sent to Military analyst carlo muñoz.

He immediately notices The latvian location

And knows it has Military significance.

much of latvia's history is Really not of their own.

They were initially occupied By the soviet union.

In world war ii, The nazis occupied the country,

And at the end of world war ii, The soviets came back in.

Narrator: Any covert nazi or soviet Military bases underground

Wouldn't show up On any civilian map.

Recently, some of these Secret underground bases

Have been rediscovered in latvia After being lost for decades.

One of the largest Was code-named rest home.

Narrator: this vast Soviet bunker was designed

To shelter the communist elite In the event of a nuclear war.

This complex is so big

That it could hold hundreds Of soviet troops

In any one of its 90 rooms.

Narrator: a maze Of secure rooms and passages,

The rest home is Over 20,000 square feet,

About the size of Two olympic swimming pools.

But many more Cold war installations

Remain undiscovered,

Some falling prey To so-called black diggers --

Illegal russian treasure hunters

Seeking lucrative Military memorabilia.

Experts ask if this water Could be escaping

Into one Of these forgotten bases

Recently cracked open For its soviet secrets.

Any one of these massive Underground soviet bunkers

Would be a perfect place For all this water to go.

Wise: If this is what's happening,

The water is creating, At least temporarily,

a kind of soviet atlantis.

narrator: And whether it's the work

of the gods, nature or man,

it's a lethal threat To anyone who gets too close.

it's too dangerous For investigators to access

the void beneath the whirlpool,

so the answer to what lies below Will continue to be a mystery.

if you don't know What's happening there,

then possibly it could collapse, And you'd be sucked down in it.

that's something that I wouldn't Want happening to me.
