National Geographic: Danger! Quicksand (1999)

Post by bunniefuu »

You're dealing with one of the

fundamental forces of nature here,

but unlike a hurricane

or even a landslide or a flood

or somethin', you can't see it.

It's lying there in wait

all the time

twenty-four hours a day.

You might just be walking along

minding your own business

and once it's got you,

it's going to hurt you.

It conforms to every single nook

and cranny of your body.

You literally cannot

pull yourself out

even if you're just up

to your ankles.

People have always been just

terrified of the idea of quicksand.

Its that awful feeling

that somehow the ground

which you know is solid and you

walk on is somehow not there,

and you're going to take a step,

and you're going to disappear.

Since the earliest days

of the cinema

it was one of Hollywood's favorite

ways to dispose of the bad guy.

Or trap an innocent victim.

Producers created bottomless pits

of quicksand out of peat moss,

oatmeal, even wine corks

And helped make the soggy

stuff legendary.

But quicksand is more than

just a clever plot device.

It's real... It's dangerous...

And it's more common

than most people believe.

Quicksand is found along

coastlines, on riverbanks,

even in our own backyards.

Though one of nature's

deadliest traps,

quicksand is made of

just two basic ingredients...

sand and water...

its a simple recipe - for disaster.

In 1997,

twelve year old Sara Cody and

a friend went for a stroll

on what looked like

a perfectly ordinary beach,

on the northwest coast of England.

We were staying at

my Auntie Jackie's holiday flat

for the weekend,

me and my friend Georgina.

We went out on the sand

we have been out before

and there is actually signs

saying quicksands

and it was a stupid thing to do,

but you don't really think

about that at the time.

You think,

"Oh, I'm not gonna sink"

It felt quite muddy at first

and it did feel like my feet

were gettin' a bit stuck,

but it just felt like

walking in thick mud.

And then it got kind of more...

liquidy.

And as I walked along,

it was all of a sudden

like a big pocket of quicksand

I stood into.

It felt like it was sucking me,

pulling me down into the sand

I tried to pull myself out,

but that made me sink

about twice as fast.

And there was people shoutin'

from the prom,

"Stop struggling

and just keep still."

I sunk up to about here-ish,

I think.

And, ahm, I remember

at first my feet didn't feel like

I had them anymore.

There was lots of sand in my wellies

and they were being dragged down.

It was liquid,

but it was going really hard

where I was puttin' pressure

onto the sand.

It was just settin'

like concrete around me.

Sara was mired deep in quicksand,

only 150 feet from the shore.

It looked just like

the rest of the beach,

but this particular patch of sand

was different.

Sara was locked so firmly in place

She couldn't get out on her own.

What we think of as solid ground

- terra firma -

isn't really solid at all.

It's billions of

separate granular particles

resting on each other.

Normally that's all it is.

But quicksand forms when rising

water levels in the ground

force the grains to lose contact,

and they float apart,

suspended in water.

The liquefied sand

can no longer support you,

so down you go.

As Sara realized too late,

struggling is a bad idea

as it only liquefies the ground

even more

so you sink further.

Trying to pull your legs up

compacts the sand tightly,

turning the water

pressure into suction,

and locking your foot in place.

The finer the particles

in the quicksand,

the tighter and

more vise-like the grip.

Word of Sara's predicament

reached the armside coast guard

who handle some 30 quicksand rescue

every year.

When I arrived on the promenade

I saw Gordon,

one of my crew,

already in there with Sarah.

She really was in a mess.

She was really frightened,

she was screaming crying,

she was just thrashing,

all she wanted to do was get out.

So I radioed, but still

we are just talking minutes.

After a while, there were

all these people around me.

It was getting really panicky.

There's lots of noise

and fire engines and police

and it seemed like

it was taking forever.

Freeing a victim from quicksand

without also getting trapped

calls for special gear.

The Arnside coast guard

uses portable planks

to cross the unstable sands

and support their weight

during the rescue.

They put a big wooden board

over my head.

It was like a big square

with a hollow in the middle.

And to pull me out,

they pulled one leg out first.

They basically dug my leg out

with their arms

they put the one leg onto the board

so I could lever my other leg out.

And then I was sort of laying

in the sand

and then they

managed to get me out altogether.

And they just picked me up...

just ran me across these boards

to the shore

and I didn't touch the floor

until I got to the ambulance.

Since it happened

I've been back once.

I came a bit onto the sands,

but I stayed mostly by the rocks

because I think I've learned

my lesson the first time...

It's not worth the hassle

of all the peoples jobs

coming out and helping you

and really

it's pointless going out there

in the first place.

In this part of England quicksand

isn't limited to the beach

where Sara was trapped.

The town of Arnside

lies near the entrance

to an enormous body of water

called Morecambe bay.

The area is well known for its

wildlife and scenic beauty.

It is also notorious

for some of the world's

most dangerous quicksand.

Sands do look nice, don't they?

And they look safe.

They always look safe

to the lay person

it looks like any old sand.

And that's its hidden danger.

For centuries,

Morecambe bay at low tide

has seduced unwary travelers,

tempting them to risk their lives

for a short cut from one village

to another by crossing the sands.

More than 150 people

are known to have perished

attempting this journey.

By itself, quicksand is not deadly

but it is the ultimate trap,

locking its victim in place

while some other force of nature

finishes the job.

In Morecambe bay,

it's a 30-foot tide.

You can never out-run it really,

because it never tires, the tide.

There is a saying in this area

that it can travel at the speed

of a galloping horse.

Well, even a horse can get tired,

but the tide never does.

To help travelers

more safely negotiate

Morecambe bay's massive tides

and infamous quicksand,

the British monarchy appointed

the first official guide

some 600 years ago.

In 1963, Cedric Robinson became

the latest in this long line

of queen's guides to the sands.

You can only know and read the sands

from bein' brought up

such as I was,

from a very early age.

There's no way you can read a book

and say, "Well, I know the route."

It doesn't work like that.

You have to know

the sands intimately

and if it can catch you out

out there,

it will do.

Cedric has lived and worked

as a fisherman on Morecambe bay

for over 50 years

and he knows its perils

better than most.

His introduction to quicksand

began at the age of fourteen.

I didn't want to do anything,

only follow the sands for a livin',

same as me father

and me grandfather,

and even me grandmother.

She was a fisherwoman.

Here on Morecambe bay,

fishing has always been

a hazardous profession.

At low tide, the bay is transformed

into a wet desert -

the fish more than seven miles

off shore.

In the old days,

locals harvested the sea

from horse and cart,

venturing out on the treacherous

sands to set their nets

and wait for the catch

to roll in with the tide.

Not everyone made it back

to safe ground.

Many foundered in quicksand,

both horse and driver drowned

by the returning tide

as it surged over their heads.

As the royal guide,

one of Cedric's responsibilities

is to educate the public

to Morecambe bay's risks by leading

"nature walks" out on the sands.

Before taking any group off shore,

he surveys the exposed flats.

Come a fine day,

before setting foot on the sands,

I can go up onto the tops, with

a marvelous view of the estuary,

and I can look through

the binoculars out there

and scan the river down

and I can say to myself

with my knowledge:

"Well, that's the place to cross."

The danger spots

are the lowest areas,

where the meandering paths of rivers

and streams carve narrow channels

in the bay...

quicksand is formed by the action

of the tides

as it raises the water table

beneath the bay,

saturating and loosening the sand

in and along these channels.

It looks just the same as any sand.

It looks firm until you stand on it

and it just goes like jelly.

And the more people

that goes over that area,

the more jellyish it gets.

There are some areas out there

where it would be

too frightening to go near them.

But there are areas

where you can go on it

and you can have fun with children.

It may seem unwise

to mix kids and quicksand,

but Cedric's hope

is to prevent future tragedies

by teaching children

how to recognize it for themselves.

Have you ever been

on quicksands before?

No.

You could get really stuck

couldn't you?

Yeah...

Yeah that's it.

It clings, doesn't it?

It's like a suction, isn't it?

So it's bad there.

And once you go on it, it's worse.

But if you come back to there,

that area in two hours,

that water will have come out

and it'll have hardened up

a little bit.

And that's the danger.

If you were in there for two hours,

we wouldn't get you out

because the water comes out

and it sets just like concrete.

Quicksand is always

the highlight of the walk,

but Cedric makes sure the kids

understand that ultimately,

it's a serious hazard.

After a certain time

one or two of them will get that

little bit deeper and -

and then it gets past

the exciting stage

and someone can get stuck.

So Cedric has to blow the whistle,

say, "Come on out of there!

I don't want to lose any of ya'."

Remember girls,

not too deep

otherwise you'll have to stay!

Usually, you find quicksand outside,

a product of mother nature.

But with the right ingredients

and know-how, you can make your own.

Scott Steedman understands quicksand

better than most.

He is a civil engineer

who has spent his professional life

studying the earth beneath our feet.

At home in the kitchen,

Scott has his own special recipe

for quicksand.

This is corn flour which

people use for thickening gravy

and it shows just all the same

properties as quicksand.

Quite extraordinary

when you mix it with water

you can change it

from this solid form,

into a liquid and back again.

And uh, let me just show you that

because I'll just put some more in,

more than I need

and we'll see if we can't make

a quicksand here in the kitchen.

The cornflower is a hard

and fine granular material,

so its a bit like sand or fine sand

but extremely fine

and so we can see in the mixture

all the same properties that

you see in a quicksand on a beach.

But really in a small scale,

here in a glass.

So this is the corn flour paste

in its liquid form.

And if I just stir the spoon slowly

you can see that it is a liquid.

Lift it up

and it drips straight back in

just like a liquid.

But if I stab at it

with a spoon quickly

like a person trying to

run across the quicksand

they don't sink in.

It is absolutely solid -

well it's undulating,

but it's solid under the tip

of the spoon.

It's got all that strength

to hold the person up.

But if the person stands still,

it just sinks in.

And then if I grab at the spoon

and try and pull it out quickly,

like I'm kicking with my legs

in the quicksand,

it locks absolutely solid.

If I kick from side to side

I just can't get it out -

it's absolutely stuck.

In the movies,

getting stuck in quicksand

was usually a terrifying experience,

and the hapless victim went to

extraordinary lengths to escape.

But in reality

there are some people around

who just can't wait to get into it.

These days my experience with it

is filming other people.

People from all walks of life.

They bring their selves

or their significant other

and they want to jump into

a bottomless pit of quicksand

to experience it,

and I provide that.

Chuck Lang is making his own

contribution to the b-movie genre.

Be looking over your shoulder

as you're running

like you hear the posse coming.

You want me to stand back here

and fire a few shots

over your head or something?

Chuck is in high demand

for his directing skills,

and for his knack

for finding quicksand,

along the banks

of the Mississippi river.

Chuck and his friends are just

a few members of an emerging network

of quicksand fanatics.

The competition is

who can find quicksand first.

And the game is what do you do

after you've found it...

It is almost like you are chained

to the ground all over.

You have to move,

you have to exercise a lot of energy

just to move a little bit.

Imagine yourself in molasses.

It's almost like an exercise.

You are going to burn some calories.

You really are.

To an outsider, playing around

with a dangerous natural phenomenon

may seem foolish.

But after years of trial and error,

these buffs have developed

an impressive understanding

of quicksand

- its realities and a few myths...

including the ones

Hollywood made up.

Don't believe what you saw on TV.

You're not going to

sink out of sight.

Perhaps its the biggest myth of all:

that you'll step into a pool

of quicksand...

And disappear.

But that's virtually impossible.

You're actually more at risk

in a pool of plain old water.

Because humans are composed mainly

of water, we won't stop sinking

until we've displaced an amount

equal to our own volume,

and that puts us

beneath the surface.

Quicksand is twice

as dense as water,

so we won't sink nearly as far,

only about chest deep.

The quicksanders have a good time

applying their knowledge

of buoyancy,

but generally they don't tempt fate.

Here on the Mississippi

the quicksand they play in

is not the most dangerous...

The sand grains are fairly large

so the grip is less "vice-like."

But just in case

something does go wrong,

they use the buddy system.

It's not a good idea

to ever go out by yourself

to look for quicksand.

Because if you find it

and you do get stuck

you could be there a while.

Bruce Fyfe certainly wasn't out

looking for quicksand

when he stumbled into it one night

in 1999 while chasing his dog.

But find it he did,

in a very unlikely place.

Basically, it's dusk,

fourth of July weekend, Friday

and I'm bookin' down

nine mile comin' back with the dog

and got approximately a little past

where the gravel pit is,

and she bolts out

the back of the truck

and I stopped the truck, took off

through the sandpiles after her.

And she goes down the hill

and got out where

they dump all their sand trappings

and stuff after they clean the rocks

and gravel off

and it's real soft there in spots

and I happened to find a soft spot.

Ended up goin' in

and basically a couple hours later

realized I was not gettin' out

without any help.

Bruce found himself knee

deep in a peculiar kind of quicksand

an unexpected by-product

of the gravel industry.

Water and fine sand particles

from the mounds of crushed rock

make this quicksand especially

"concrete-like"

and difficult to escape.

Bruce was locked in

and looking at an extended stay.

As my feet went into it

and got locked

you could actually feel it

encasing my feet and part of my leg.

From probably mid point

from my shins

down to the bottoms of my feet

I couldn't feel anything.

You know it was just...

they were dead.

And I wasn't going forward,

backwards, up or down,

and I was stuck.

I think

I resigned myself to the fact

that I was probably going to

be there overnight,

'cause I... you know,

very little traffic,

everybody's gone...

I could hear the expressway traffic,

but that's a couple miles away

and just well,

I'll wait 'til morning

and just start all over again.

And, it just got progressively

hotter through the weekend

and by the third day

I did drink the water

that was around me.

I was just to that point

where I knew something was happening

to me physically,

because

I couldn't focus on anything.

Bruce was suffering from

more than just dehydration

and prolonged exposure.

At this point,

he'd been trapped for three days

and four nights...

more than 60 hours,

and was dealing with

a frightening effect of quicksand:

a crushing pressure on his limbs.

Moving his legs back and forth

had compacted the quicksand.

The pressure had increased

until it actually cut off

the blood supply to his legs.

Eventually, Bruce lost all feeling

in his lower extremities

as the cells,

nerves and tissues were starved of

essential oxygen and nutrients

supplied by blood flow.

When the quicksand stuff

the material

it was just like

if you were squeezing

on your legs hard as this

but it went from his mid-thighs

all the way down his leg,

just a total squeeze down to

around his foot

and kind of just squished it

right up...

I guess you could

make the comparison

to being in a vise-like situation...

Believe me coming on

to the third morning

I wanted out.

I wanted to go home.

Bruce's endurance test

finally came to an end

when the sun rose

on Tuesday morning.

I heard the machinery start

and I started screaming,

and some guy popped up over the bank

and he says,

"How long have you been here?"

And I told him and I said

roll the rescue squad

and get me some water.

They tried digging

with some shovels.

They really couldn't

because we were worried about

some injuries to his legs.

They dug with some screwdrivers

a couple of inches at a time

running their

hands down his legs to make sure

they were not poking into them.

Because he couldn't feel his legs,

from the knees

down to around his feet.

He had no feeling in there

from being compacted for so long.

As soon as my feet came free

they just pirouetted me up

and got me down on the backboard

and got me out of there...

I was tired, I was hot,

and I was just trying to

stay with it.

I didn't realize

I had developed an infection,

my kidneys had started to shut down,

and there was a lot of weird things

wrong inside of me

that I really couldn't tell.

The big thing I knew was

that my feet were messed up.

Bruce's kidneys were treated

and soon back to normal,

but his feet were another matter.

When tissues are starved of blood

and oxygen long enough,

they die,

which can lead to gangrene.

In the worst cases

toes or even legs are amputated.

Sometimes if I move my foot

just right I get a real bad twinge

and that could still be just

scar tissue breaking apart.

The Doctor said it could be a year

before your feet get back to normal.

Time could have been

Bruce's real enemy

but luckily,

his rescuers reached him

before permanent injury set in.

In a swamp north of Toronto,

it was the combination of quicksand

and cold Canadian weather

that spelled disaster

for nine year old Ethan Beattie.

The nightmare began

one chilly spring afternoon

when Ethan and his friend Steven

took a wrong turn

while playing in the backwoods

near their homes.

I got stuck at one point

and Steven thought that

me and Elmo were behind him,

so he went on.

And then we were separated.

We were looking for this path

that would take us back

but we ended up in the swamp.

As they searched for a way home,

the ground beneath their feet

began to give way.

Well, it looked like it was solid,

but when you stepped,

you would start to sink,

and it looks like it's shallow

but when you step in your leg...

it will get deeper.

Steven managed to find his way home

and told his mother

that Ethan and Elmo

were still lost in the swamp.

As darkness fell,

police and local rescue squads

organized an extensive search.

You could see the lights of the

fire trucks and the police cars.

There was lots of commotion

and you could see people massing

down at the corner here,

waiting to go in on foot

to do a search.

The rescuers had their work

cut out for them.

Ethan had disappeared in the heart

of a three square mile swamp

and it was already dusk

when the search began.

We'd also been informed

by the police officers

that had gone out ahead of time

that there was quicksand.

So there's a danger out there

that we were actually told not to

actually leave the boat

unless we had a visual contact

with the boy.

You hope for the best,

but you expect the worst,

you don't want to go up there

all pumped thinking

you're going to find somebody alive,

because if you don't,

especially a child.

If you don't find them alive

that's devastating.

For several hours

the rescue team scoured the swamp

but there were no signs

of Ethan or the dog

I can't imagine

what a little nine year-old boy

is thinking,

when it starts to get dark,

he can see the helicopter,

he can hear

the people looking for him.

Ahm, he can't answer because

it's starting to get too cold.

He's gotten too far.

He can't get back.

He's getting stuck.

The only thing he's got with him

is his dog.

As the night wore on,

Ethan's situation

grew more desperate.

Stuck in quicksand,

his body trapped

in near-freezing swamp water,

he was in real danger

of dying from exposure.

Elmo the dog sensed Ethan

was in trouble,

and stayed close to the boy.

When I got too cold.

Elmo would lie on me

and when I was falling asleep,

Elmo would lick my face

so I would stay awake.

Every 15-20 seconds

we would call out his name,

hoping that we'd get a response.

More than five hours

after the search began,

the beam of Dave Pierce's spotlight

reflected off the eyes of an animal

crouched in the reeds.

We got probably within about 50 feet

and I was able to see

a slightly black shape

and then we knew it was a dog.

When we came upon the boy

and Dale shouted out

"He's alive!" boy, that was it.

The adrenaline's pumpin'

and we're basically running

across there to get to him.

And to find him still alive;

still alert...

OK, now we've got a chance.

By now, Ethan was ice cold

and extremely weak,

sunk deep in the quicksand.

I was up to here in mud

and it was, they would -

I think they were pullin' me a lot

to get me out.

But the soft wet ground

nearly thwarted the rescuers'

efforts to free Ethan

and get him into the boat.

Dale picked him up.

He turned around,

he took one step and boom

he went down to his chest

in quicksand.

It scared the hell out of us.

We knew it was there,

but we didn't step in it before

The men formed an assembly line,

handing Ethan off to each other

as they wrestled with the quicksand.

They struggled for solid footing

and slowly maneuvered

back to their craft.

It was close to eleven o'clock

when the rescue team

finally carried Ethan to shore.

After seven hours in the cold swamp

he was in a state of severe shock,

and deeply hypothermic.

His body temperature had fallen to

within just a few degrees

of cardiac failure.

Had Ethan been in the quicksand

much longer,

he may not have survived.

Wandering into swamps

and getting stuck in quicksand

is one thing.

But Lil Judd certainly

never expected

to find it in her part of the world.

You've heard about quicksand.

You hear about it, but...

but I'd be able to locate it

basically in my back yard,

no. No, that, I didn't expect.

Though Hollywood has produced some

pretty good fakes over the years,

California seems an unlikely

candidate for real quicksand.

Of the two main ingredients,

there's more than enough sand,

but this dry state

can be short on water.

But in 1998

heavy rains had turned a normally

dry gully just east of Hollywood

into a quicksand trap.

We rode out on the sandbank

and we were standing out there

for maybe five minutes.

And he decided to take

a step forward and it had a drop.

Suddenly all of him was in

and I looked around and realized

he had actually literally sunk,

because as I'm trying to tell him

"Get up,"

he's trying to get up,

but he can't.

For a moment there,

I just went panicky

and I sat down next to him

and started crying.

The thing with horses

and animals in general

when they're in a panic situation

like this,

they will either give up

or very possibly they'll go insane.

So all I could do

was hope he understood

from my tone of voice.

I gotta go.

I gotta leave you.

I can't get you out on my own.

I have to get help.

I'll be back. Don't move.

Lay as still as you can."

Now Lil had to

avoid getting herself trapped

in the same quicksand

that held her horse.

I ran across this area

and kept sinking down to my hip.

I just grabbed at whatever I could

and pushed against whatever I could

and just never allowed myself

to remain too long

in the same place.

Help was not long in coming,

but once the rescue efforts

had begun,

destined's situation

quickly went from bad to worse.

He ends up in the stream.

And all I could think was

"oh my god,

With all these people here,

he's gonna drown.

I am going to watch him drown.

With a lot of encouragement,

destined was able to thrash his way

out of the water,

but the weight of

his 1600 pound body,

concentrated on four narrow hooves,

made it impossible for the horse

to get out of the quicksand.

As a last resort,

a helicopter was brought in

to airlift him to solid ground.

Somehow they managed

to get this harness on him

and they started lifting him.

He is flying up in the air.

And he's slipping out

of the harness.

And I'm saying, "Put him down.

Put him down."

But the first place destined landed

wasn't solid enough

to support his weight.

He continued to flounder

in the quicksand

until his rescuers adjusted

his harness

and tried a second airlift.

No one ever said,

"You know,

we can't save this horse."

No one ever said that to me.

And I'm sure a lot of people

were thinking it

when they saw what he looked like

and where he was.

This time,

the helicopter pilots gently

lowered destined onto firm ground.

Despite four hours in quicksand

and two precarious airlifts,

the horse was unharmed.

He was up and walking again

in just minutes.

I am one very,

very lucky horse owner!

And he's one very, very lucky horse.

Lil and destined were fortunate.

There were enough people, expertise

and technology to save the day.

But that hasn't

always been the case.

In the 19th century,

there were few resources available

to American cowboys.

While driving their herds of cattle,

they encountered quicksand

on a regular basis as they tried to

ford sand-laden rivers.

Hauling a two-ton steer

out of quicksand was no easy matter.

The best they could do was

try and pull the animals free

with ropes.

But unfortunately, things didn't

always go like clockwork.

As one weary cowboy put it,

"this last method

saved many bogged down cattle,

but it tore the heads, horns or

legs off quite a few others."

The cattle of the old west were lost

in small patches of quicksand.

But sometimes quicksand

can spread for miles...

and swallow a city.

Perhaps the most remarkable

case occurred in 1692.

The city of Port Royal, Jamaica -

at the time,

one of the wealthiest cities

in the new world -

was resting quietly

on its foundation -

a sandy spit of land

Just before noon on June 7th,

a huge earthquake shook the ground

with tremendous force.

The violent motion pushed seawater

up through the loose sand.

In a process called liquefaction,

the entire peninsula beneath

Port Royal

turned to quicksand.

When the shaking finally stopped

after ten minutes,

a third of the city had slid

into the sea,

and 2000 people were dead.

The water had drained back

out of the ground,

locking people into graves

of hardened quicksand.

Written accounts from survivors

describe some

of the most horrifying moments.

"No place suffered like Port Royal

where whole streets

were swallowed up

by the opening earth and houses

and inhabitants

went down together...

Some were swallowed up to the Neck,

and then the Earth shut upon them,

and squeezed them to death...

some were left buried with their

heads above ground.

"The shake opened the earth;

the seawaters flew way up

and carried the people in alive.

I lost my husband, my son

and all I ever had in the world"

Port royal went down

more than 300 years ago,

but despite the hazard,

we still build cities on low-lying,

sandy areas near rivers or the sea.

The phenomenon of liquefaction

is of vital concern to engineers

who must factor in the risk

of quicksand conditions

whenever they plan new construction

in earthquake zones.

At the university of Bristol

in England,

Scott Steedman uses models

to demonstrate

how buildings will react

when the ground beneath

turns to quicksand,

as it did in port royal.

We're building a beach here

to demonstrate some

of the properties of quicksand.

It's a special sort of quicksand,

because it's a quicksand

that's formed in an earthquake.

The shaking in an earthquake

creates extra water pressure

in the ground

and that boils up to the surface

and produces all the same phenomena

as quicksand.

This is the ocean down here,

and stretching up the slope here

is the beach

and behind the beach

here is the flat ground,

behind where you may have a town

or people...

This is quite a high building

next to a rather steep slope.

On a shaking table,

Scott subjects his model high rise

to simulated earthquakes of seven

or eight on the Richter scale -

magnitudes easily strong enough

to liquefy the earth,

and turn it to quicksand.

You can see how the building

has sunk in and rotated here,

mainly because the slope

has given way beneath it.

And so that's forced it to tilt

over this direction.

As the shaking progressed,

the water pressure's built up

in the sand underneath

the foundation of the bottom block,

and as that happened

the ground got softer.

And with the shaking

and the frequency of the earthquake,

it started to get more

and more dramatic and in the end,

of course, with the lean becoming

more and more pronounced,

eventually the top blocks just

rolled off and fell down the hill.

Just east of anchorage,

Alaska is Turnagain arm,

a 50 mile long fjord

filled with quicksand.

Over the eons, the slow movement

of glaciers has ground hard rock

from the mountains around the arm

into an extremely fine powder.

Meltwater carries that

powder downstream

and into the waters

of Turnagain arm.

When the tide retreats,

a vast expanse of glacial silt

is exposed.

In Alaska,

they call this the mud flats.

But when these tiny particles

mix with subsurface water

from the incoming tide,

this powdered rock has all

the properties of deadly quicksand.

More than a million people

visit Alaska every year.

Many of them come to enjoy

the waters of Turnagain arm.

Most have no idea

they are in serious danger

of getting stuck.

The Lukens family has lived beside

Turnagain arm for thirty years,

but despite knowing

about the quicksand,

they've turned the fjord

at low tide into a playground.

We've never had any trouble

getting out of the mud.

Of course, you know,

we don't sit there

and see how deeply we can

get ourselves imbedded either.

We try and get out right away

and move...

As long as you keep moving

you really don't get stuck.

So far the Lukens have been lucky.

But that's not always the case.

Most people are tourists,

and they go out there

and they think it is

a relatively safe area

They play around with it

They know the stuck

of this kind of lake below

and they stay with it

and then they play with it.

and then they get one ankle stuck

and they try to pull that out.

They get the second ankle stuck

and pretty soon they're

they're in up over their knees.

As usual,

quicksand is just the trap.

In Turnagain arm,

the real K*llers are the cold water,

and the enormous tide,

the second highest in the world.

It is swift and extreme,

rising forty feet

in less than six hours.

Rescuing people from quicksand

is tough enough.

Trying to beat a racing tide

ups the stakes dramatically.

Four times a year,

the Girdwood fire department

runs a thorough simulation

to check their gear,

and make sure every member

of the team is ready

for a real life quicksand rescue.

Dan sill is

the operations commander.

When we show up on scene

we are going to go out,

we are going to

evaluate the situation,

evaluate the mud and the currents

and the tides and the winds

and everything else.

We'll make a game plan.

We'll either set up a person

here or here.

Everything we do out there,

we've trained for it numerous times.

Everybody knows what the game plan

is, including the victim.

We'll take Bob out there

and put him the mud no more

than his knees.

There are plenty of suitable areas

in Turnagain arm to stage a drill.

Some of the worst quicksand

is just off the highway.

This salty peninsula

thirty-five miles east of Anchorage

is perfect for testing

the Girdwood team's rescue skills.

It has all the hazards they face

on real calls,

including the debilitating element

of cold.

This mud is the same temperature

water is -

about 45 degrees,

which is really, really cold.

And if you're out here

without the proper

protective equipment on,

you're gonna get hypothermic

when you struggle to get out of it.

You're gonna get cold.

You're gonna get exhausted,

and you're going to take and go down

and die real quick.

Having the right clothes

can make the difference

between a successful rescue

and a fatality.

Full dry suits, life jackets,

and helmets protect the men

and increase the amount of time

they can spend working to

free a victim from cold quicksand.

Mike Tumey has been with the

department for more than a decade.

He knows all too well the pressure

of trying to rescue someone trapped

and in desperate circumstances.

In 1988,

he witnessed one of

the saddest quicksand tragedies

in recent Alaskan history.

Mr. and Mrs. Dickison were newlyweds

and, ah,

they had a little more gumption

than most of us and had chose to

spend their honeymoon, ah,

gold mining up in Seattle Creek,

which is just around

the corner here.

To get there in their four-wheeler,

they had to travel

across the mud flats.

Jay and Adeana Dickison headed out

early in the morning

to catch the low tide...

Just three hundred yards off shore,

their four wheeler bogged down

in the silt.

Adeana jumped off

to push from behind.

But struggling with the atv

liquefied the ground

beneath her feet

and she sank up to her knees.

When she stopped moving

the quicksand closed

around her legs with an iron grip.

Her husband labored frantically,

but after three hours

he had only managed to free

one of Adeana's legs.

By the time jay ran for help,

the tide was pouring into

Turnagain arm.

About nine o'clock in the morning

we got a call for

a, ah, possible victim

stuck in the mud.

We responded from the station.

It's about a half-hour response time

to this location,

hiked on the trail

with all of our equipment

As I reached the shoreline,

I heard the screams of a young woman

crying for help

"Please don't let me drown.

Please save me."

There was a, ah, woman

trapped in the rising waters

with the water just below her chin.

I went below the surface to try

and feel

what was taking place there,

I felt her leg and it seemed to

disappear in the sand

and I thought, "She's buried

all the way up to her knees,"

you know, probably straight down.

And at that point

I tried to tug on her leg,

But when I came up,

I saw her gasping for breath.

So every time I tugged her,

I pulled her under.

Each time it's violent.

I'm pulling with

even more strength now,

but each time it's jerking her

under the water

and thrashing her

at the same time.

I go under again to try

and free her leg

and when I come back up

she's under the water now.

The tide's gone over her hand

and everything was in a...

small circle.

All I could see was this little area

here in front of me,

but I'm looking down into her face

and she's under the water

holding her breath.

And I'm thinking, you know,

"What a desperate situation this is.

What a... you know,

this brave woman she,

despite all the odds,

she's gonna...

she's gonna stick with us.

She's gonna fight with us

all the way to the end."

Anyway, I didn't know what to do.

She's underwater now

and she's holding her breath

and, I can't thrash her now

because she's got one breath left.

At that point, ah, her husband

took a...

a tube off their suction dredge

and they stuck it in her mouth.

And, I...

I stroked her forehead and said,

"Just keep breathing,"

and I went down again to try

and free her leg

and I just pulled as hard

as I possibly could

and I just sat there.

"We've got to get her out,"

you know,

pulling as hard as I possibly can

and, ah, I couldn't free her.

While mike struggled

beneath the surface,

the tide continued to rise.

When he finally came up for air,

Adeana Dickison had drowned.

It wasn't until low tide

later that afternoon

the, ah, rescuers that went back

to recover her, ah,

found her, ah,

still where we'd left her,

ah, still trapped just from the knee

down by one leg in the mud

and at an angle like this.

The tide had come in swept over her,

gone back out with all that force

and that leg was still trapped,

snared in that mud.

They had to dig her out

with shovels.

The tragedy devastated

the Girdwood team.

On that fateful day,

they were beaten by the rising tide

and a lack of time.

For more than eleven years

they've continued searching for ways

to perfect their techniques

and speed up their operation.

I literally spent months and months

dreaming and fantasizing

about a tool

that I could build that

I could expedite the rescue.

And literally in minutes.

What Dan sill came up with turned

the Girdwood team's greatest enemy

into their most important ally.

Water became the key component

in their fight against the clock.

For everything to work,

the floating pump

which capitalizes on the water

around them must be kept running.

I just want you guys to make certain

if something does happen

and does go wrong

that we are relyin' on you.

So no matter what it takes,

that pump is your responsibility.

You can not let it shut off.

I don't want to freak you out

or anything,

but once Bob's in the mud

he's our responsibility.

So we're not gonna let him die.

OK, I'm up to my knees

Feel like you're sinking anymore?

A little.

I'm ready.

You ready?

Ready.

Go ahead, fire it up!

The float-a-pump sucks water up

through the hose

and into

a long perforated metal tube.

High pressure blasts of water

liquefy the dense quicksand

and unlock the grip on Bob's legs.

With the new device, the extrication

takes less than a minute.

After each run-through,

the team gathers for a debriefing.

I could not move my legs

I could feel it.

It felt like cement was around them.

And the more I tried -

before Scott was there,

I was just playing around -

but the more I tried the further

I was sinking.

The thing is,

what typically these people do,

and I was watchin' you do that,

is, ah, they'll get one foot stuck,

so they'll try to pull this one out.

This one goes deeper.

Then they realize that and they go,

"I'll stand on this foot,"

and they'll try to pull that out.

Then that one goes deeper.

So they're caught

in a see-saw motion

where they're goin' back and forth

and they're actually forcin'

themselves to get deeper.

So once both feet are in

what are you going to do

if you can't

get either one of them out?

Concentrate on one foot.

Wiggle one foot to get one foot out.

That foot gets on the highest piece

of ground that you can find.

Then you work on that one.

And vibration is what'll get it out.

What if both are in

and you aren't getting them

to move at all?

You need to fall forward

on your belly,

get all your weight off... off...

Sometimes it's not possible

because you're up to your knees.

What you have to do is

get the weight off of one point

and work to get one...

one leg out or one foot out,

roll 'til you can get

the other one out,

do a roll and run for high ground.

The bottom line is...

is you shouldn't be out there.

It's - there's nothing...

nothing for you out there.

It is just nothing but danger,

and I've said it again

and I've said it before.

It's you're flirting with the devil.

You're literally flirting

with the devil.

Sadly, Dan and his colleagues,

along with rescuers

around the world,

fight that devil all too often.

Quicksand by itself

is not the k*ller,

but locked in its relentless grip,

any one of it's accomplices:

time, tide, cold or heat

can finish us off.

Again and again, we seem to ignore

the warning signs

and fall prey to one

of the world's most insidious traps.

Quicksand can be found

almost anywhere.

So the safest bet

is to watch your step.
