My name's Steve Backshall.

0:00:020:00:04

And this...is Deadly Pole To Pole.

0:00:060:00:09

Ohhh!

0:00:090:00:11

From the top of the world to the bottom.

0:00:110:00:13

Whoa!

0:00:130:00:15

Deadly places.

0:00:150:00:17

Deadly adventures.

0:00:170:00:18

And deadly animals.

0:00:180:00:20

And you're coming with me, every step of the way!

0:00:210:00:24

Arghhhh!

0:00:260:00:27

This time the team and I have come to Yellowstone, it's the oldest

0:00:300:00:34

national park in the world, routinely the coldest place

0:00:340:00:38

in North America, and also a sensational place

0:00:380:00:41

to go looking for winter predators.

0:00:410:00:43

We're on the trail of an American giant...

0:00:450:00:49

Be careful, Steve.

0:00:490:00:51

..specialist hunters...

0:00:510:00:52

..and the voice of the wilderness.

0:00:540:00:56

HE HOWLS

0:00:570:00:59

White Fang himself, the wolf.

0:00:590:01:02

Go, go, go!

0:01:020:01:04

We've just seen a couple of wolves.

0:01:040:01:06

Oh, wow!

0:01:060:01:08

Yellowstone spans three North American states -

0:01:100:01:13

Montana, Idaho and Wyoming.

0:01:130:01:15

It's a protected pristine wilderness the size

0:01:180:01:20

of a small country.

0:01:200:01:22

My main mission here is to go looking for the top dog

0:01:270:01:30

in North America, and my favourite animal in the world, the grey wolf.

0:01:300:01:34

They're intelligent, complicated

0:01:380:01:40

cooperative hunters, and one of the most ruthless

0:01:400:01:44

and relentless of all predators.

0:01:440:01:46

In this wintry wilderness the wolf rules,

0:01:470:01:50

but they're so canny that finding and filming them

0:01:500:01:53

will be almost impossible.

0:01:530:01:54

Their territories can span hundreds of square miles.

0:01:590:02:01

They're incredibly perceptive and will doubtless

0:02:030:02:05

sense us before we see them.

0:02:050:02:07

We're going to need to be adaptable to stay on their trail.

0:02:100:02:13

This vehicle is absolutely brilliant.

0:02:140:02:16

Essentially someone's just taken an old van,

0:02:160:02:19

pulled the wheels off and welded a tank to the bottom of it.

0:02:190:02:22

To have any chance of seeing wolves, I'm going to need some luck,

0:02:240:02:27

all of my tracking skills and an eagle-eyed crew.

0:02:270:02:31

Well, I suppose you can't have everything.

0:02:320:02:34

Method number one is to get eyes on the wolf's favoured prey.

0:02:380:02:42

We've just spotted from the road some brown shapes

0:02:450:02:49

moving slowly on the other side of this tree line here,

0:02:490:02:51

so we'll approach really quietly and see if we can get a look.

0:02:510:02:54

Down at the river's edge there are several elk,

0:03:080:03:12

it's a large species of deer, and here in Yellowstone

0:03:120:03:15

this is the main prey species that the wolves are after.

0:03:150:03:18

At this time of year they're at a considerable disadvantage

0:03:200:03:23

because they have to break down through the snow

0:03:230:03:25

to get at the grass, and also to munch on these conifers,

0:03:250:03:29

none of which have an awful lot of nutrients in them.

0:03:290:03:31

So as the winter goes on they start getting weaker and weaker,

0:03:310:03:34

and more and more ripe pickings for the wolf.

0:03:340:03:37

The wolves know the elk are here,

0:03:400:03:42

and may well be within striking distance.

0:03:420:03:45

We've pulled up because it appears that something quite dramatic

0:03:490:03:53

has happened alongside the road here.

0:03:530:03:56

Loads of fur at the verge...

0:03:560:04:01

and what looks like a chunk of pelt right here.

0:04:010:04:04

Look at that. Wow.

0:04:070:04:10

That is a fairly complete chunk of skin from an elk.

0:04:100:04:17

This, though, has been dragged up onto the road,

0:04:180:04:20

the kill didn't happen here,

0:04:200:04:22

it looks like it happened just over there.

0:04:220:04:23

Wow, there is sign absolutely everywhere.

0:04:250:04:30

So when you're approaching something like this,

0:04:330:04:35

it's a bit like approaching a crime scene, you've got to be

0:04:350:04:38

very careful where you put your feet, because all of these marks

0:04:380:04:42

- though they look like a mess -

0:04:420:04:44

they're actually signs of what's gone on here,

0:04:440:04:46

and that looks like it was the epicentre...of the kill.

0:04:460:04:51

Yeah, oh, my goodness, there is blood everywhere, look at that!

0:04:510:04:55

That's really kind of gory,

0:04:570:05:01

and instantly to me this just says "wolf kill".

0:05:010:05:05

You might have five or six animals all competing for food, they'll get

0:05:050:05:09

their teeth stuck into it, they'll wedge down with their big paws

0:05:090:05:12

on straight legs and just shake,

0:05:120:05:15

using all of the muscularity in their neck,

0:05:150:05:17

and it ends up kind of looking like a butcher's shop floor.

0:05:170:05:20

I know some people might think I'm insane,

0:05:240:05:27

but that to me is a really wonderful sight. It's poo.

0:05:270:05:32

It's poo, but it's twisted with a tapered end

0:05:320:05:35

and full of deer hair. And it's wolf,

0:05:350:05:40

that is definitely wolf poo.

0:05:400:05:43

It's difficult to tell how fresh it is

0:05:430:05:45

because it's obviously been really cold here,

0:05:450:05:48

so it's frozen solid, but they were here within the last couple of days.

0:05:480:05:53

WOLVES HOWL

0:05:540:05:55

The wolf pack is more than just a family unit, it's an organised team

0:05:550:06:00

that opens up endless opportunities.

0:06:000:06:02

Working together, they can bring down prey far larger

0:06:040:06:07

than any single wolf could handle.

0:06:070:06:09

When prey is spotted, the lightest

0:06:140:06:16

and fastest wolves take the lead...

0:06:160:06:18

..while others circle around the quarry,

0:06:200:06:22

or save their energy - waiting to take over when the others tire.

0:06:220:06:26

They target a weak, old, young or injured animal,

0:06:290:06:32

separating it from the herd.

0:06:320:06:34

Once they have their target alone and vulnerable,

0:06:380:06:41

the whole pack charge in. It's a gruesome end

0:06:410:06:45

for this elk, but ultimately ensures

0:06:450:06:47

the elk herd stays strong, their weaker members

0:06:470:06:50

falling to one of the world's top predators.

0:06:500:06:52

'Unfortunately, here the trail's gone cold.

0:06:540:06:57

'It's time to get back on the road.'

0:06:570:06:59

The snow wagon rumbles on.

0:07:060:07:07

But then, just the lead we were hoping for.

0:07:110:07:14

A pack has been spotted 70 miles to the north.

0:07:140:07:17

It's a big journey, but probably our best chance.

0:07:170:07:21

It's all very different here, we're lower in altitude

0:07:210:07:23

and there's less snow.

0:07:230:07:24

Our plan now is just to drive this road, keeping our eyes peeled

0:07:240:07:29

for any sign of a wolf.

0:07:290:07:30

Really it's all now down to my team keeping their eyes on the prize.

0:07:300:07:35

'This could be a very long car ride.'

0:07:370:07:39

We've tried to film wolves on Deadly before,

0:07:450:07:47

and it's always one of our toughest challenges.

0:07:470:07:49

But after a day and a half of endless driving,

0:07:510:07:54

staring desperately off into the snow,

0:07:540:07:56

finally a sighting.

0:07:560:07:58

Go, go, go!

0:07:590:08:01

Don't worry, just bring it round to the front with you, Stevo.

0:08:010:08:05

There's two wolves!

0:08:070:08:08

We've just seen a couple of wolves walking towards the road.

0:08:160:08:22

At the moment they're about a mile away,

0:08:220:08:25

but it's possible they could come close enough that we can get

0:08:250:08:28

a shot of them on the camera.

0:08:280:08:31

The wolf's been my favourite animal for many years,

0:08:310:08:35

but in the wild I've only caught fleeting glimpses of them.

0:08:350:08:38

They're so, so hard to film.

0:08:380:08:40

I mean, it's not an endangered animal, there are still thousands

0:08:400:08:46

of them here in North America, but no-one ever sees them.

0:08:460:08:50

They are very, very shy, very elusive animals,

0:08:500:08:53

and the chance of seeing one relatively close

0:08:530:08:57

in the middle of the day is incredibly exciting.

0:08:570:09:00

Let's just get off the road.

0:09:000:09:02

This is great, yeah, this is great.

0:09:040:09:07

Oh, wow!

0:09:090:09:12

They're trotting on so quick cos...

0:09:120:09:13

-BREATHLESS:

-Yeah, that's fantastic, two wolves out in the open.

0:09:160:09:22

And really closer than I expected to get.

0:09:240:09:27

So what we've got is a male and a female wolf,

0:09:310:09:35

at least one of them is wearing a radio collar,

0:09:350:09:38

that's put on by biologists so that they can track

0:09:380:09:40

the movements of these animals and make sure they keep them safe.

0:09:400:09:43

Phew. Oh, they're so beautiful.

0:09:430:09:46

'I can't tell you how rare this is.

0:09:500:09:52

'Some people live their whole lives in this region

0:09:520:09:55

'without seeing a wolf.

0:09:550:09:56

'Seeing them run free here in broad daylight is even more special,

0:09:560:10:00

'because 30 years ago they'd been wiped out

0:10:000:10:02

'from most of the United States.

0:10:020:10:05

'Now, this top predator is making a comeback.'

0:10:050:10:07

This is really, really exciting. My heart's going crazy.

0:10:090:10:13

Here he comes, coming almost at a trot,

0:10:130:10:17

that loping gait, wolves can keep that up

0:10:170:10:19

for a great deal of time if they have to.

0:10:190:10:21

That's one of their big advantages when they're hunting,

0:10:210:10:24

is their endurance. Heading towards the road,

0:10:240:10:26

it looks like it might cross right in front of that car up there.

0:10:260:10:29

Oh, look at that!

0:10:300:10:31

The most incredible view of a wild wolf ever.

0:10:390:10:42

Well, it was chaotic, but it was very, very exciting

0:10:470:10:50

and a sight that most wildlife watchers

0:10:500:10:52

would give their right arm for.

0:10:520:10:54

You have to say, wolves in the winter wonderland

0:10:540:10:57

- massive success and definitely Deadly.

0:10:570:11:00

Phenomenal endurance hunters.

0:11:050:11:07

With jaws that can crush bone.

0:11:090:11:11

An unparalleled intelligent pack predator.

0:11:130:11:16

There's no doubt that

0:11:180:11:19

wolves are Deadly.

0:11:190:11:20

VOICE WHISPERS: Deadly!

0:11:200:11:23

So the wolf may be the top of the line predator

0:11:240:11:26

here in the Yellowstone snow,

0:11:260:11:28

but it is nothing like the biggest or most powerful animal here.

0:11:280:11:32

That creature...has a skull...

0:11:320:11:35

..that looks like this.

0:11:380:11:39

This belongs to the largest land mammal found on the whole continent

0:11:410:11:48

- the bison.

0:11:480:11:50

Weighing as much as a tonne, these raging bulls

0:11:510:11:54

are a formidable force to be reckoned with.

0:11:540:11:57

Bison injure more people in Yellowstone

0:11:570:11:59

than wolves and grizzly bears put together.

0:11:590:12:01

And as we're tracking them on foot,

0:12:030:12:04

we need to keep sharp.

0:12:040:12:06

They're through the trees here,

0:12:100:12:11

the snow's going to be very, very deep,

0:12:110:12:14

possibly waist, even chest-deep, so we've got snowshoes on

0:12:140:12:17

to try and keep us up above it as much as possible.

0:12:170:12:20

'But even with snow shoes, we're struggling.'

0:12:200:12:23

HE LAUGHS

0:12:240:12:25

-Having trouble there, Aaron?

-Uh?

0:12:250:12:27

-Are you having trouble there?

-No, it's fine.

0:12:270:12:29

We're heading for a meadow where we hope the bison will be feeding,

0:12:310:12:35

and all the kit needs to be dragged in my sled.

0:12:350:12:38

It feels like I'm towing a truck behind me.

0:12:380:12:41

Now this is what I've been really hoping to find.

0:12:430:12:46

It's a bison track, AND...look at that!

0:12:480:12:52

It's... Oh, it's very fresh, it's fresher than I expected!

0:12:580:13:02

That is bison poo!

0:13:020:13:04

-Oh.

-HE SNIFFS

0:13:050:13:07

Really, really fresh, laid within the last hour or so,

0:13:070:13:10

in fact, it's still warm inside,

0:13:100:13:12

you could put your hands into it and use it as a glove.

0:13:120:13:15

'Yeah, I don't think that'll catch on.

0:13:170:13:19

'Still, it means we're close.

0:13:190:13:21

'And then, through the trees, we get our first glimpse.'

0:13:210:13:24

So, ahead of us is exactly what we'd hoped for.

0:13:310:13:34

The bison are still a decent distance away,

0:13:360:13:39

but once we start getting closer

0:13:390:13:40

we're going to have to be really quite careful.

0:13:400:13:43

BISON GROWL AND SNORT

0:13:530:13:55

Bison are bovids,

0:13:580:14:00

or bovine animals, which means they're in the cow family.

0:14:000:14:03

If your idea of a cow is a big friendly Friesian

0:14:030:14:07

chewing the cud, then you couldn't be more wrong.

0:14:070:14:10

I mean, this is a group of animals that contains things

0:14:100:14:13

like the water buffalo, the Cape buffalo and the bison themselves.

0:14:130:14:16

These are creatures that are deceptively fast,

0:14:160:14:19

very strong and powerful,

0:14:190:14:20

and can be very grumpy and unpredictable.

0:14:200:14:23

During their summertime rut, male bison show off

0:14:270:14:30

their full lethal potential when they joust for females.

0:14:300:14:33

These beefy battering rams slam into each other

0:14:370:14:40

with enough force to crumple steel.

0:14:400:14:43

The strongest male with the thickest skull gets the girl,

0:14:430:14:47

and all these brutal, bulky battles

0:14:470:14:49

produce bulls that can really take care of themselves.

0:14:490:14:52

They are incredibly powerful animals, and a lot of that

0:15:020:15:06

you can see in the muscularity behind the head.

0:15:060:15:08

There's a huge hump which is just muscle, used to hold up that

0:15:080:15:12

huge bony skull. These animals will use those in battles

0:15:120:15:17

with each other, but also in fighting off their mortal enemy

0:15:170:15:20

- the wolf.

0:15:200:15:21

The battles between bison and wolves

0:15:250:15:27

are a showdown of brains versus brawn.

0:15:270:15:29

Like a wolf pack, bison have strength in numbers.

0:15:340:15:37

And their most effective defence is stampeding.

0:15:400:15:43

Bulldozing through deep snow,

0:15:470:15:49

the herd is like an unstoppable freight train.

0:15:490:15:51

The largest animals form an outer wall of muscle,

0:15:540:15:57

hooves and horns - protecting the smaller, weaker ones.

0:15:570:16:00

Often the wolves will realise they're outnumbered and outgunned,

0:16:010:16:04

and will just leave hungry.

0:16:040:16:05

But when they do go into combat,

0:16:070:16:08

it's a brutal spectacle.

0:16:080:16:11

The wolves have bite, guile, grit and determination.

0:16:110:16:14

The bison have horns that could pierce through a car door,

0:16:140:16:18

and kicks that can shatter bone.

0:16:180:16:20

WOLF WHINES AND BISON GRUNTS

0:16:210:16:25

As a deadly defender, they demand respect,

0:16:250:16:28

even from the fiercest of predators.

0:16:280:16:30

Oh, he's coming.

0:16:330:16:34

'And back at the car, we got a first-hand reminder

0:16:340:16:38

'when a large male caught us by surprise.'

0:16:380:16:41

-Everyone, come, come this way.

-Be careful, Steve.

0:16:410:16:44

We need to get right back to the car, guys.

0:16:450:16:47

You need to back up a bit. Guys, back,

0:16:520:16:54

Johnny, back. Maybe behind the car. Johnny.

0:16:540:16:59

Nothing is going to get in the way of this bison juggernaut.

0:17:050:17:08

Fantastic.

0:17:120:17:13

Weighing a tonne.

0:17:190:17:21

With lethal dagger like-horns.

0:17:230:17:26

Capable of stampeding at 30mph.

0:17:280:17:30

Bison are bovine bad boys, and decidedly...

0:17:310:17:35

VOICE WHISPERS: Deadly!

0:17:350:17:36

We're now travelling deep into the remotest part of Yellowstone.

0:17:400:17:43

Here I'm hoping to find some very specialist predators

0:17:460:17:49

that have learned how to survive this frozen heartland.

0:17:490:17:52

There's a bald eagle sat on a tree.

0:17:550:17:57

(Wow!)

0:17:590:18:00

What a sight!

0:18:020:18:03

Our base camp is right in the middle of Yellowstone,

0:18:060:18:09

surrounded by endless wilderness.

0:18:090:18:13

We're going to be staying in these kind of garden shed things,

0:18:130:18:17

they're called lavvu, this one's mine right here.

0:18:170:18:20

It looks kind of cosy. All right, what else have we got?

0:18:200:18:23

We've got stacks of skis for getting around,

0:18:230:18:26

really important in the snow,

0:18:260:18:28

but out there is the snowy wilderness

0:18:280:18:30

that we've come here to explore.

0:18:300:18:32

'And the nearby frozen river offers up our first surprise specialist.'

0:18:340:18:38

Ah, yes, well spotted.

0:18:430:18:45

'If only this water weasel would stay still long enough

0:18:450:18:47

'for us to get a shot.'

0:18:470:18:49

Yes, otter! Got it.

0:18:500:18:52

He's just dived into the ice.

0:18:540:18:55

Really quick, isn't he?

0:18:570:18:59

'Otters can travel a quarter of a mile underwater on a

0:19:000:19:03

'single breath, there's no way of guessing where he'll pop up next.'

0:19:030:19:07

He is leading us a merry dance!

0:19:100:19:12

I've totally lost him, I've got no idea where he is.

0:19:130:19:16

HE LAUGHS

0:19:160:19:17

This otter is definitely foraging or looking for food,

0:19:190:19:23

so as he's moving up the river he's doing repeated dives,

0:19:230:19:26

heading down probably towards the bed.

0:19:260:19:29

There he is, Johnny, Johnny! Really clear.

0:19:310:19:33

Oh, wow!

0:19:370:19:38

'Out of the water we get a glimpse of the streamlined body and

0:19:400:19:44

'long muscular tail that make otters such agile underwater hunters.'

0:19:440:19:48

They are constantly in and out of the water searching for food,

0:19:500:19:54

and that could be a decent-sized fish,

0:19:540:19:56

it could be things like crayfish, or it could be water birds, frogs.

0:19:560:20:02

They are extraordinary predators.

0:20:020:20:04

Underwater, otters come into their own. They're superbly agile,

0:20:070:20:10

with a bendy spine and short limbs they can twist

0:20:100:20:13

and turn towards prey, which they target with

0:20:130:20:16

long tactile whiskers.

0:20:160:20:18

The whiskers are so sensitive that the otter can

0:20:180:20:21

perceive prey in murky or pitch-black night-time waters.

0:20:210:20:25

They can even track a fish's movements by

0:20:250:20:28

the invisible wake it leaves behind.

0:20:280:20:29

They can hunt as family groups

0:20:320:20:34

and take fish almost as big as themselves.

0:20:340:20:36

Needle-sharp teeth and claws hold on to their slippery suppers.

0:20:420:20:46

They have the ability to gorge themselves,

0:20:510:20:53

eating 20% of their body weight a day,

0:20:530:20:55

even here in Yellowstone's icy rivers.

0:20:550:20:58

These ultra tough, aquatic acrobats are a real find.

0:20:580:21:03

(Oh, Johnny, Johnny, Johnny!)

0:21:030:21:05

(It's just down below us.)

0:21:100:21:11

(Looking straight at us.)

0:21:120:21:13

(Beautiful.)

0:21:150:21:16

Ah, this is brilliant. He's just rolling on his back

0:21:200:21:25

on the ice, like he's having a really good scratch.

0:21:250:21:29

That is brilliant.

0:21:310:21:32

It's hard to believe when you see them

0:21:340:21:36

like this, just looking like a big teddy bear,

0:21:360:21:40

that this animal could be one of the

0:21:400:21:42

most voracious predators you will ever see.

0:21:420:21:44

'So, the otter's a genuine contender.'

0:21:460:21:49

But there are plenty more snow-time specialists here.

0:21:510:21:54

And they've left a story behind in the snow.

0:21:540:21:56

There's a really interesting trail of tracks

0:22:000:22:02

running over this flat slope in front of us,

0:22:020:22:04

and you can see where a fox has come along.

0:22:040:22:07

And it's been walking in a track and it's,

0:22:070:22:10

it's going round in big circles.

0:22:100:22:12

Oh, very, very fresh, he's certainly still in the area.

0:22:120:22:15

Could well be watching us right now.

0:22:170:22:19

'And sure enough...'

0:22:210:22:22

Wow!

0:22:240:22:26

'..the fox is just 50 metres away.'

0:22:290:22:31

(Look at that, isn't he pretty?)

0:22:330:22:35

He is definitely on the hunt, nose down

0:22:360:22:40

close to the snow, listening, smelling,

0:22:400:22:43

all his senses on high alert.

0:22:430:22:45

'Red foxes are in the dog family like wolves,

0:22:470:22:49

'but have very different lives.

0:22:490:22:52

'They're a great opportunist and can find a meal almost anywhere.

0:22:520:22:55

'They have adapted to live in forests,

0:22:560:22:58

'deserts and even cities, but I've never seen them looking

0:22:580:23:01

'more majestic than here.'

0:23:010:23:02

That's so beautiful. Wow.

0:23:050:23:10

The small rodents the red foxes like to snack on

0:23:140:23:18

very, very rarely come out into the open, even at night

0:23:180:23:21

at this time of year. Instead they're scuttling around in tunnels

0:23:210:23:24

underneath the snow, and the red fox can hear them moving,

0:23:240:23:27

even as much as my height in depth beneath the snow,

0:23:270:23:31

it'll still hear their movements, the ears are that sensitive.

0:23:310:23:34

Pinpointing their prey is just the start.

0:23:370:23:40

Next, they have to catch it.

0:23:400:23:42

Its hunting strategy is, well, as cunning as a fox!

0:23:430:23:48

Punching down into the snow, it's hit the jackpot.

0:24:000:24:05

An unsuspecting vole becomes lunch.

0:24:070:24:10

This is truly one of the ultimate ambush specialists.

0:24:110:24:14

Well, they might be the smallest member of the dog family here,

0:24:160:24:19

but they're still undeniably lethal.

0:24:190:24:22

They can track prey under two metres of snow.

0:24:270:24:30

Adaptable enough to survive almost anywhere.

0:24:310:24:34

A silent assassin.

0:24:360:24:37

The red fox wins my award for

0:24:390:24:41

best specialist hunter.

0:24:410:24:43

VOICE WHISPERS: Deadly!

0:24:430:24:45

This leg of my Pole to Pole journey has provided

0:24:470:24:50

some spectacular lethal encounters.

0:24:500:24:53

Everyone, come this way.

0:24:530:24:55

But we're not leaving just yet.

0:24:560:24:58

Because Yellowstone has a secret

0:25:020:25:04

more deadly than anything we've seen.

0:25:040:25:06

On the surface this may look like a magical frozen wonderland,

0:25:090:25:14

but something sinister is stirring beneath.

0:25:140:25:16

At various places in Yellowstone you find features

0:25:240:25:26

like these, they're called geysers.

0:25:260:25:28

It's where superheated steam and water rushes to the surface

0:25:280:25:31

and squirts up, it could be as tall as an office block,

0:25:310:25:34

and these are all a clue that there's something

0:25:340:25:36

pretty special and very, very dangerous happening beneath my feet.

0:25:360:25:41

The geysers are being heated by a force of nature

0:25:410:25:44

so earth-shatteringly massive it's hard to get your head around.

0:25:440:25:47

Yellowstone sits in the 50 mile-wide crater of a super volcano.

0:25:500:25:55

If it erupts, it could be the largest natural disaster

0:25:570:26:00

in the history of humankind.

0:26:000:26:02

It will have a force thousands of times

0:26:090:26:11

greater than a normal volcano.

0:26:110:26:13

MUSIC: "Earthquake" by Labrinth

0:26:170:26:22

Enough power to blast away entire mountains,

0:26:220:26:25

throwing hundreds of miles of rock and debris into the atmosphere.

0:26:250:26:29

Most of the United States could be covered

0:26:370:26:39

in a blanket of ash and rock.

0:26:390:26:41

Dust clouds would obscure the sun for months all over the world,

0:26:420:26:46

causing global temperature to plummet.

0:26:460:26:48

It could trigger a new ice age.

0:26:480:26:51

Even the tropics could end up looking like

0:26:510:26:53

Yellowstone does right now.

0:26:530:26:55

It tends to erupt about every 600,000 years.

0:26:560:27:00

The last time it erupted was about 640,000 years ago,

0:27:000:27:03

so we're well overdue.

0:27:030:27:04

A super volcano that could completely change

0:27:040:27:07

the course of life as we know it.

0:27:070:27:09

That is definitely Deadly!

0:27:090:27:11

A slumbering giant.

0:27:140:27:15

And possibly the most powerful force of nature on the planet.

0:27:180:27:21

Yellowstone's super volcano

0:27:250:27:27

is as deadly as it gets.
