Narrator:
THEY'RE WATCHING YOU.

MORE THAN 4,000 SATELLITES
CIRCLE THE EARTH.

EVERY DAY, THEY UNCOVER NEW,

MYSTERIOUS PHENOMENA
THAT DEFY EXPLANATION.

[ BEEPING, DISTORTED MUSIC ]

THE LAND OF MEDUSA, WHERE LIVING
THINGS ARE TURNED INTO STONE.

Phoenix: EVERYTHING ON HIM
HAS SOLIDIFIED.

HE'S ESSENTIALLY BECOME
PART OF THE LANDSCAPE.

Narrator: NOTHING MOVING --
THE TOWN THAT FALLS ASLEEP.

WHEN THEY WAKE UP
FROM THIS LONG SLEEP,

THEY HAVE NO MEMORY
AT ALL OF WHAT HAPPENED.

Narrator: AND THE TOMB
OF THE GOD GIANT ANTAEUS.

SOMEBODY WAS BURIED THERE --
BUT SOMEBODY REALLY BIG.

Narrator: BAFFLING PHENOMENA.

MYSTERIES FROM SPACE.

WHAT ON EARTH ARE THEY?

MARCH 6, 2017 --

AS NASA'S LANDSAT 8 SATELLITE

PASSES OVER
NORTHEASTERN TANZANIA,

IT CAPTURES AN IMAGE
OF A STRANGE GLOWING LAKE.

RED IS ALL YOU SEE.

THIS LAKE APPEARS TO BE
THIS MONSTROUS PRESENCE --

SO UNNATURAL A COLOR.

THIS LAKE LOOKS LIKE THE RUNOFF

FROM AN INDUSTRIAL
SLAUGHTERHOUSE.

Narrator: BUT THAT'S NOT ALL.

THE LAKE IS KNOWN
AS THE MEDUSA LAKE.

THEY SAY IT TURNS ANYTHING
THAT TOUCHES IT INTO STONE.

THE LEGEND IS THAT MEDUSA
WAS A BEAUTIFUL WOMAN.

Kourounis: ATHENA CURSED HER.

[ THUNDER CRASHES ]

ANYONE WHO GAZED DIRECTLY UPON
HER WOULD BE TURNED TO STONE.

**

Narrator: MEDUSA IS BEHEADED
BY THE GREEK HERO PERSEUS,

AND HER BLOOD DRIPS ONTO AFRICA.

BUT THE MEDUSA LAKE IN THE IMAGE
HASN'T ALWAYS BEEN RED.

PREVIOUS SATELLITE IMAGES
SHOW THAT ITS COLOR IS CHANGING.

**

GEOLOGIST JESS PHOENIX
IS INTRIGUED

BY THE LAKE'S
STRANGE CHAMELEON WATERS

AND THE LEGEND OF LIVING THINGS
TURNING INTO STONE.

SHE TRAVELS 10,000 MILES
TO KILIMANJARO,

THEN JOURNEYS NORTHWEST
TO INVESTIGATE

THE EERIE LAKE UP CLOSE.

I'M ON MY WAY TO VISIT THE WEIRD
RED LAKE ON THE SATELLITE IMAGE.

THE COLOR APPEARS IN PATCHES.

AND THAT'S JUST STRANGE TO ME.

THIS IS DEFINITELY NOT
WHAT YOU'D SEE

IN MOST HEALTHY LAKE ECOSYSTEMS.

IS IT CONTAMINATION
OR SOMETHING ELSE ENTIRELY?

**

Narrator:
AS SHE APPROACHES THE LAKE,

SHE NOTICES WHAT APPEARS TO BE
A PATTERN OR GRID OF STONES

STRETCHING INTO THE DISTANCE.

OH, WOW.

THIS...IS REALLY COOL.

THIS IS NOT NATURAL.

YEAH, THIS IS MANMADE.

Narrator:
IT SEEMS THAT THESE STRUCTURES

ARE THE REMAINS OF AN ABANDONED
ANCIENT SETTLEMENT.

PHOENIX LEARNS THAT THESE RUINS
ARE ALL THAT'S LEFT

OF WHAT WAS ONCE A THRIVING
COMMUNITY CALLED ENGARUKA.

BUT AROUND 300 YEARS AGO,

EVERYONE LIVING HERE
MYSTERIOUSLY DISAPPEARS.

FOR A WHOLE COMMUNITY
JUST TO PICK UP AND LEAVE,

SOMETHING REALLY BAD
MUST HAVE HAPPENED.

WE'RE TALKING
THOUSANDS OF PEOPLE HERE.

**

Narrator:
AS PHOENIX SURVEYS THE SITE,

SHE DISCOVERS EVIDENCE
OF AN ANCIENT WATERING SYSTEM.

MY GUESS IS THAT THESE PEOPLE
CHANNELIZED THE RIVER

AND WATER FLOWED DOWN.

AND THEN THEY COULD SHUT THIS
TO KEEP WATER IN AND THEN FARM.

Narrator: SHE WONDERS WHETHER
THE WATER FLOWING INTO THIS TOWN

COULD HAVE ANYTHING TO DO

WITH THE SUDDEN
DISAPPEARANCE OF ITS PEOPLE.

WHAT WOULD MAKE
THE PEOPLE LEAVE?

'CAUSE THERE'S STILL
WATER AROUND TODAY.

Narrator: SHE CONSIDERS
IF THIS WATER MIGHT BE FLOWING

OUT OF OR INTO THE MEDUSA LAKE
SEEN IN THE SATELLITE IMAGE.

**

PHOENIX PRESSES ON TO THE LAKE
TO INVESTIGATE FURTHER.

**

Phoenix: OH, WOW!

Narrator: THE LAKE IS VAST --
STRETCHING 340 SQUARE MILES.

BUT IT'S NOT GLOWING RED.

IT APPEARS ALMOST NORMAL.

AS PHOENIX APPROACHES
THE SHORELINE,

SHE NOTICES STRANGE
SKELETONS ON THE GROUND...

SKELETONS WHICH APPEAR
TO BE MADE OF STONE.

Phoenix: THIS IS NOT NORMAL.

WHEN SOMETHING DIES, EVERYTHING
SCAVENGES IT, USUALLY.

IN THE DESERT, NOTHING'S WASTED.

Narrator: THE STONE SKELETONS
ARE PLANTED IN THE GROUND

LIKE STATUES.

IT'S A LITTLE RODENT,
AND IT LOOKS...

IT LOOKS FROZEN.
IT'S TWISTED.

I CAN'T DISLODGE
THIS LITTLE GUY.

EVERYTHING ON HIM
HAS JUST SOLIDIFIED.

HE'S ESSENTIALLY BECOME
PART OF THE LANDSCAPE.

Hunt: NO WONDER IT'S CALLED
THE MEDUSA LAKE.

IT'S A MONSTROUS PLACE
THAT TURNS ANIMALS TO STONE.

**

Narrator: TO SOLVE THE MYSTERY
OF THE STONE ANIMALS,

PHOENIX GOES IN SEARCH OF
AN AREA OF THE LAKE THAT'S RED.

**

Phoenix: I MEAN, LOOK AT THIS.
THIS IS...

THIS REDNESS,
YOU DON'T SEE IT EVERY DAY.

Narrator: ON CLOSER INSPECTION,

PHOENIX DISCOVERED WHERE
THE WEIRD COLOR COMES FROM.

IT'S JUST AN ABUNDANCE OF LIFE.

IT'S PRIMITIVE, BUT IT'S LIFE.

Narrator: THE LAKE IS TEEMING
WITH MICROSCOPIC CREATURES.

THERE ARE TINY ORGANISMS
CALLED CYANOBACTERIA

THAT THRIVE IN THIS ENVIRONMENT.

AND IT TURNS OUT THEY'RE RED.

Narrator: WHEN THE POPULATION
OF THESE CREATURES EXPLODES,

THE MEDUSA LAKE
BECOMES A SHOCKING RED.

SO MUCH FOR THE COLOR.

BUT WHAT ABOUT
THE ANIMAL STATUES?

PHOENIX HOPES HER ANALYSIS
OF THE WATER

WILL SHED SOME LIGHT
ON THE MYSTERY.

ALL RIGHT.

9.3, 9.4.

Narrator: THE TEST REVEALS
BIZARRE LEVELS OF ALKALINITY.

THIS IS WELL HIGHER
THAN WHAT IT SHOULD BE.

Narrator: WHAT'S MORE,
A STRANGE WHITE CRUST

SURROUNDING THE LAKE
IS SIMILARLY CAUSTIC.

Phoenix: OH, YEAH.
THAT'S BEAUTIFUL.

DEFINITELY CARBONATE ROCK.

Narrator: WHAT SHE FINDS
LEADS PHOENIX TO BELIEVE

THAT THE LAKE MUST CONTAIN
EXTRAORDINARY LEVELS

OF A CARBONATE SUBSTANCE,

HIGHLY VALUED BY THE
ANCIENT EGYPTIANS -- NATRON.

NATRON IS A SUBSTANCE
THAT HAS BEEN USED

THROUGHOUT ANCIENT HISTORY,

MOST NOTABLY IN EGYPT
WITH THE CREATION OF MUMMIES.

Narrator: NATRON SUCKS WATER
FROM DEAD BODIES,

LIKE A VAMPIRE DRINKS BLOOD.

AND THAT'S WHAT MAKES IT
SO IMPORTANT FOR PERSEVERATION.

Narrator: SIMILARLY, THE STRANGE
ANIMAL STATUES AROUND THE LAKE

BECOME IMMERSED IN THE NATRON
WATER AND ARE MUMMIFIED.

BUT PHOENIX STILL DOESN'T KNOW

WHERE SUCH A POWERFUL
CONCENTRATION OF CHEMICALS

MIGHT HAVE COME FROM.

SHE RETURNS TO
THE SATELLITE IMAGES

AND SCANS IS FOR FURTHER CLUES.

YOU KNOW, WHAT I'VE NOTICED
IS THAT THERE'S A VOLCANO

JUST TO THE SOUTH OF THE LAKE

THAT LOOKS LIKE IT'S GOT SOME
RELATIVELY FRESH LAVA FLOWS.

Lester: JUST 20 OR 30 MILES
SOUTH OF THE LAKE

IS ONE OF THE MOST
UNUSUAL VOLCANOES IN THE WORLD.

Narrator: LOCALS CALL IT
THE MOUNTAIN OF GOD.

COULD IT HOLD THE KEY
TO THE HELLISH WATERS

OF THE MEDUSA LAKE?

**

COMING UP,
THE TOWN OF THE LIVING DEAD.

THEY GET WEAK. THEY PASS OUT.
THEY START FALLING ASLEEP.

Narrator:
AND JESS PHOENIX GETS UP CLOSE

WITH THE MOUNTAIN OF GOD.

Phoenix: I HAVE BEEN ON
VOLCANOES ALL OVER THE WORLD,

AND I HAVE NEVER BEEN
ANYWHERE LIKE THIS.

**

Narrator:
AFRICA, NORTHERN TANZANIA.

GEOLOGIST JESS PHOENIX
IS EXPLORING

THE STRANGE MEDUSA LAKE

THAT TURNS LIVING THINGS
INTO STONE.

CAN IT EXPLAIN THE MYSTERIOUS
DISAPPEARANCE OF A NEARBY TRIBE,

THE ENGARUKA?

IN SEARCH OF ANSWERS,
PHOENIX GOES TO THE VOLCANO,

WHICH STANDS OMINOUSLY CLOSE.

IT IS CALLED OL DOINYO LENGAI.

THE MAASAI PEOPLE
LIVE IN THIS AREA,

AND THAT VOLCANO IS SACRED.

**

Narrator: BEFORE CLIMBING
THE SACRED VOLCANO,

SHE APPROACHES
THE MAASAI VILLAGE AT ITS BASE

TO TALK WITH THE TRIBE ELDER.

[ BOTH SPEAKING
NATIVE LANGUAGE ]

Narrator: PHOENIX LEARNS
THAT ACCORDING TO THE MAASAI,

THE VOLCANO IS HOME
TO THE GOD ENGAI.

WHEN HE IS ANGRY, THE VOLCANO
ERUPTS AND CAUSES TERROR

ALL AROUND, WHICH IS WHY
THE MAASAI PERFORM

SACRIFICES TO THE VOLCANO GOD.

Narrator: BUT SACRIFICES
ARE NOT ALWAYS ENOUGH

TO PACIFY THE VOLCANO.

IN 2007, THERE ARE A SERIES
OF TERRIFYING ERUPTIONS

ON THE MOUNTAIN OF GOD,
WHICH LAST ALMOST A YEAR.

IT IS DEFINITELY ONE OF THE MOST
DANGEROUS VOLCANOES IN AFRICA.

**

Narrator: THE NEXT MORNING,

PHOENIX SETS OFF
ON THE TREACHEROUS CLIMB

UP THE SACRED VOLCANO

TO INVESTIGATE ITS LINK
TO THE MEDUSA LAKE.

Phoenix:
IT'S GOOD THAT IT'S EARLY.

AND IT LOOKS NICE AND
CLEAR AND QUIET, BUT...

YOU CANNOT TRUST A VOLCANO.

**

Narrator: THE TERRAIN IS HARSH.

THE TEMPERATURE, PUNISHING.

**

ABOUT HALFWAY UP THE MOUNTAIN,

PHOENIX STUMBLES
UPON HER FIRST CLUE --

A CHANNEL LINED WITH
AN UNEXPECTED SUBSTANCE.

Phoenix:
THIS PLACE IS SO UNUSUAL.

YOU DON'T GET WHITES LIKE THIS
AT OTHER VOLCANOES.

Narrator: ON CLOSER INSPECTION,

SHE REALIZES
SHE'S LOOKING AT

COOL HARD LAVA
FROM PREVIOUS ERUPTIONS.

I HAVE BEEN ON VOLCANOES
ALL OVER THE WORLD,

AND I HAVE NEVER BEEN
ANYWHERE LIKE THIS.

THIS IS ABSOLUTELY INCREDIBLE.

THESE ARE NOT NORMAL LAVAS --
NOT AT ALL.

THE LAVA THAT COMES OUT
OF OL DOINYO LENGAI

IS THIS CRAZY,
FROTHY SORT OF STUFF.

Brand: IT RUNS ACROSS
THE SURFACE LIKE WATER.

IN FACT, THIS IS ONE
OF THE ONLY LAVAS IN THE WORLD

THAT YOU CAN'T OUTRUN.

Narrator:
AND WHEN THE LAVA HARDENS,

IT TURNS FROM GRAY-BLACK
TO A GHOSTLY WHITE.

PHOENIX KNOWS SOMETHING BIZARRE
IS GOING ON ON THIS VOLCANO.

WHAT SHE NOW NEEDS TO ESTABLISH

IS HOW IT MIGHT BE CONNECTED
TO THE MEDUSA LAKE.

**

Phoenix: THAT'S WHAT I WANTED.

**

OH.

9.8.

VERY ALKALINE.

THIS IS NATROCARBONATITE.

THIS IS THE ONLY VOLCANO
IN THE WORLD LIKE THIS.

Kourounis:
WE FOUND OUR SMOKING GUN HERE.

THE SAME CHEMICAL ELEMENTS
THAT ARE FOUND IN THE LAKE

ARE ALSO FOUND IN THE LAVA
FROM OL DOINYO LENGAI.

Narrator: BUT SOMETHING
STILL DOESN'T MAKE SENSE.

A VOLCANIC ERUPTION WILL SEND
THE STATUE-FORMING NATRON

DOWN INTO THE MEDUSA LAKE,

BUT NOT IN NEARLY
SUFFICIENT QUANTITIES.

THE LAKE HAS A VOLUME
OF 90 BILLION GALLONS.

PHOENIX HAS A HUNCH
WHAT MIGHT BE GOING ON

AND RETURNS TO THE LAKE.

YEP.
THAT IS A HOT SPRING.

THERE'S WATER FLOWING OUT
OF THE VALLEY FLOOR RIGHT HERE.

Narrator: A HOT SPRING
IS EVIDENCE THAT THE LAKE

IS DIRECTLY LINKED
TO THE VOLCANO

THROUGH AN INTRICATE SYSTEM
OF UNDERGROUND FAULTS.

IT TURNS OUT THAT
THE PLUMBING SYSTEM

UNDERNEATH THESE VOLCANOES
IS VERY COMPLEX.

Narrator: IT IS POSSIBLE
THAT IF THE SACRED VOLCANO'S

UNDERGROUND TENTACLES REACH
AS FAR AS 20 MILES OR MORE,

THAT AT ONE TIME, THE DEADLY
MIXTURE OF MOLTEN NATRON

REACHED
THE UNFORTUNATE ENGARUKA,

AND THEY BECAME VICTIMS
OF THE CURSE OF MEDUSA.

Sanford: IF THIS VOLCANO
SPREAD ALKALINITY,

MAYBE THE WATER BECAME TOXIC
AND ALL THEIR CROPS DIED.

IT'S POSSIBLE ALL THE PEOPLE
COULD HAVE STARVED.

THAT WOULD DAMAGE THEIR CROPS,
IT WOULD RUIN THAT WHOLE

INTRICATE SYSTEM
OF IRRIGATION THAT THEY HAD.

AND IT WOULD MAKE LIFE
IN THAT SPOT IMPOSSIBLE.

Narrator:
WE MAY NEVER KNOW FOR CERTAIN

WHETHER IT WAS THE CURSE
OF THE MEDUSA LAKE

WHICH KILLED OR FRIGHTENED
AWAY THE ENGARUKA,

BUT THERE IS GOOD REASON
FOR THE LOCALS TO REVERE

AND FEAR THIS STRANGE
AND TERRIFYING VOLCANO.

**

COMING UP, REVEALED FROM ABOVE,
A GIANT MYSTERY IN MOROCCO.

WHAT'S THE MOUND
DOING IN THE MIDDLE?

I BET YOU THAT'S WHAT THEY
THOUGHT WAS THE GIANT'S TOMB.

AND THE UNEXPLAINED
SLEEPING BEAUTY TOWN.

Sanford: THE IDEA OF A TOWN
CATCHING SOME KIND

OF A SLEEPING SICKNESS

THAT'S TOTALLY UNEXPLAINED
IS JUST FRIGHTENING.

Narrator:
AS THE GEO I-1 SATELLITE

PASSES OVER
NORTHWESTERN KAZAKHSTAN,

IT CAPTURES AN IMAGE
OF TWO NEIGHBORING TOWNS

ON THE BANKS OF THE ISHIM RIVER.

TO THE EAST IS A NORMAL TOWN.

BUT TO THE WEST,
THE SATELLITE SHOWS KRASNOGORSK.

IT IS DEAD --
NOTHING AND NOBODY IS MOVING.

Krueger: IT'S REALLY STRANGE
TO HAVE THESE TWO TOWNS

NEXT TO EACH OTHER.

WHAT HAPPENED TO THE CITY
ON THE LEFT?

Sanford:
WHAT MADE IT A GHOST TOWN

WHEN EVERYONE IS STILL
LIVING RIGHT NEXT DOOR?

Narrator: THE SATELLITE IMAGE
YIELDS FEW CLUES,

BUT WHEN INVESTIGATORS
CONSULT LOCAL REPORTS,

THEY UNCOVER A BIZARRE
SERIES OF EVENTS.

AN UNEXPLAINED SLEEPING SICKNESS
IS SWEEPING THROUGH THE AREA.

PEOPLE ALL OF A SUDDEN
START BECOMING ILL,

BUT IN SUCH A STRANGE WAY.

THEY GET WEAK, THEY PASS OUT,
THEY START FALLING ASLEEP.

Narrator:
FOR NO APPARENT REASON,

RESIDENTS SUDDENLY COLLAPSE.

CAN YOU IMAGINE SITTING IN
YOUR HOME WITH YOUR CHILDREN,

WATCHING TELEVISION,
AND THEN ALL OF A SUDDEN,

YOU LOOK AROUND AND ONE OF THEM
IS COMPLETELY ASLEEP,

YOU CAN'T GET THEM UP.

Narrator: AS THEY SLEEP,
THEY HALLUCINATE.

THEY SEE SNAKES IN THEIR BEDS
AND WORMS EATING THEIR HANDS.

Krueger: THEY IMAGINE SNAILS
CRAWLING ALL OVER THEIR BODY.

THEY FEEL LIKE THEIR HEADS
ARE GOING TO EXPLODE.

Narrator: LIKE A TOWN
OF SLEEPING BEAUTIES,

VICTIMS CAN STAY
ASLEEP FOR DAYS.

WHEN THEY WAKE UP
FROM THIS LONG SLEEP,

THEY HAVE NO MEMORY
AT ALL OF WHAT HAPPENED.

Narrator: INVESTIGATORS LOOK
FOR POSSIBLE CLUES

IN THE INDUSTRIAL
HISTORY OF THE AREA.

DECLASSIFIED RUSSIAN DOCUMENTS
REVEAL THERE WAS

ONCE A URANIUM MINE JUST
TWO MILES OUTSIDE KRASNOGORSK.

DURING THE 1950s, THE SOVIETS
DISCOVERED URANIUM DEPOSITS

LOCATED RIGHT NEXT TO THIS TOWN.

Narrator: KAZAKHSTAN IS SITTING
ON 15% OF THE WORLD'S

KNOWN URANIUM DEPOSITS.

THEIR URANIUM HOLDINGS
WERE AN IMPORTANT RESOURCE

AS THE SOVIETS DEVELOPED
THEIR NUCLEAR WEAPONS PROGRAM.

Narrator: DURING THE SOVIET ERA,

THE NOW GHOST TOWN
OF KRASNOGORSK

WAS A BUSTLING CITY.

BUT ITS MAIN INDUSTRY SHUTS DOWN
QUITE SUDDENLY IN 1991.

Krueger: THE IRON CURTAIN
COLLAPSED AND KAZAKHSTAN

BECAME ITS OWN
INDEPENDENT NATION,

SO AT THAT POINT,
THERE WAS NO NEED

TO CONTINUE
THE URANIUM-MINING OPERATION.

Narrator:
WITHOUT WORK, MOST RESIDENTS OF

KRASNOGORSK ARE FORCED TO LEAVE,

BUT FOR THE FEW STAYING BEHIND,

THE CONSEQUENCES
ARE EVEN MORE DEVASTATING.

Baker: THE RUSSIANS
JUST UP AND LEFT.

IT WASN'T AS IF THEY SAID,

"WELL, NOW WE REALLY NEED
TO CLEAN THIS SITE UP.

WE NEED TO THINK ABOUT HOW TO
MAKE THIS PLACE SAFE

FOR HUMAN OCCUPATION."

THEY DIDN'T CARE.

Narrator: AT FIRST, SCIENTISTS
THINK THERE MIGHT BE

A CONNECTION BETWEEN THE CLOSURE
OF THE URANIUM MINE

AND THE MYSTERIOUS
ZOMBIE DISEASE.

THIS HAS TO BE PART
OF THE CAUSE HERE

AND, WHEN INVESTIGATORS GO
AND TAKE A LOOK AT THE MINE,

THEY FIND THAT
IT'S LEAKING RADON GAS.

Narrator:
RADON GAS IS A DEADLY PRODUCT

OF THE RADIOACTIVE DECAY
OF URANIUM ORE.

THIS NOTION OF A TOXIC GAS
LEAKING OUT OF A MINE

AND POISONING
A NEARBY POPULATION,

DRIVING THEM TO THIS KIND
OF MASS PSYCHOSIS,

IT'S ALMOST LIKE SOMETHING
OUT OF A STEPHEN KING NOVEL.

Narrator:
BUT THERE'S A PROBLEM.

RADON GAS IS INDEED DEADLY.

IT CAN CAUSE LUNG CANCER,
BUT IT DOESN'T PUT YOU TO SLEEP.

Carter: RADON GAS DOESN'T
EXPLAIN THIS WEIRD SICKNESS.

IT DOESN'T EXPLAIN WHY PEOPLE
WERE SLEEPING FOR DAYS ON END,

SO THERE'S STILL
A MYSTERY THERE.

Narrator: FOLLOWING TESTS
IN THE LOCAL AREA,

THE KAZAKH GOVERNMENT RELEASES

ITS OFFICIAL EXPLANATION
OF THE EVENTS.

KAZAKH OFFICIALS ANNOUNCE
THAT THE CARBON MONOXIDE LEVELS

WERE 10 TIMES BIGGER THAN WHAT
THEY WERE SUPPOSED TO BE.

Narrator:
CARBON MONOXIDE IS DEADLY.

IT STARVES THE BODY OF OXYGEN.

CARBON MONOXIDE COMPETES
AGAINST OXYGEN IN THE BLOOD

AND BINDS MORE READILY,

SO AS PEOPLE ACCUMULATE
MORE CARBON MONOXIDE

IN THEIR BLOOD SYSTEM,

THEIR BRAIN IS, ESSENTIALLY,
BECOMING DEPLETED OF OXYGEN.

IF YOUR BODY'S TRYING
TO CONSERVE OXYGEN

AND SLOW DOWN ITS METABOLISM,

WHAT EASIER WAY TO DO
THAT THAN GO TO SLEEP?

Narrator:
IF THIS IS WHAT'S HAPPENING,

ANIMALS TOO SHOULD BE AFFECTED,
BUT THEY AREN'T.

UNTIL FURTHER INDEPENDENT TESTS,

THE SOURCE
OF THE KAZAKH ZOMBIE DISEASE

REMAINS A MYSTERY.

Chamberlain: THE REALLY
STRANGE PART ABOUT THIS, TO ME,

IS THAT A LOT OF PEOPLE
WANT TO INVESTIGATE

WHAT'S HAPPENING HERE,
BUT THE KAZAKHSTAN GOVERNMENT

IS NOT LETTING PEOPLE IN
TO FIND OUT.

Narrator: IN ANY CASE, KAZAKH
OFFICIALS AREN'T TAKING

ANY RISKS
AND THE REMAINING RESIDENTS

ARE BEING RELOCATED.

THE STRANGE NIGHTMARE CONTINUES.

**

COMING UP,
ALIEN ACTIVITY IN AUSTRALIA.

THERE HAVE BEEN REPORTS
OF VERY STRANGE AIRCRAFT

AND BLUE AND GOLD LIGHTS.

Narrator: AND AN ANCIENT STONE
RING HIDDEN IN PLAIN SIGHT.

THIS IS CLEARLY JUST AN
INCREDIBLE FEAT OF ENGINEERING.

**

Narrator: HISTORIAN ANDREW GOUGH
HAS BEEN STUDYING

ANCIENT MONUMENTS
FOR OVER 20 YEARS.

SCOURING IMAGES OF NORTH AFRICA,

HE COMES ACROSS A STRUCTURE
THAT BAFFLES HIM.

A SATELLITE HAS CAPTURED
WHAT APPEARS TO BE

A LARGE, STONE CIRCLE.

**

Gough: EVERYONE KNOWS ABOUT
THE STONE CIRCLES IN BRITAIN.

YOU HAVE STONEHENGE, AVEBURY.
YOU HAVE HUNDREDS OF THEM.

WHAT'S A STONE CIRCLE
DOING IN MOROCCO?

Narrator: GOUGH DISCOVERS THE
STONE CIRCLE IS CALLED MSOURA,

BUT FINDS VERY
LITTLE ELSE ABOUT IT.

**

IN SEARCH OF ANSWERS, HE TRAVELS
TO THE ANCIENT CITY OF MARRAKESH

AT THE FOOT
OF THE ATLAS MOUNTAINS.

**

GOUGH MAKES HIS WAY TO MSOURA
IN THE FAR NORTH OF MOROCCO,

OVER 300 MILES AWAY.

**

BY PREHISTORIC STANDARDS,
THIS SITE IS GIGANTIC.

Gough: FANTASTIC.
LOOK AT THAT.

THAT'S GOT TO BE,
WHAT, 15 FEET TALL?

Narrator:
GOUGH COUNTS 168 MASSIVE STONES.

THEN HE NOTICES
SOMETHING UNUSUAL

ABOUT THE CENTER OF THE CIRCLE.

Gough: WHAT'S THE MOUND
DOING IN THE MIDDLE?

I BET YOU THAT'S WHAT THEY
THOUGHT WAS THE GIANT'S TOMB.

Narrator: FROM THE LIMITED
MATERIAL AVAILABLE,

GOUGH KNOWS THE ROMANS
BELIEVED MSOURA

WAS THE TOMB
OF THE SON OF POSEIDON,

GOD OF SEA AND WATER,
AND GAIA, THE EARTH GODDESS.

ACCORDING TO LEGEND,
THE GOD-GIANT ANTAEUS

IS INVINCIBLE
UNTIL HE ENCOUNTERS HERCULES.

HERCULES IS THE STRONGEST MAN
ON EARTH, BUT THAT'S JUST IT.

HE'S STILL A MAN WHEREAS ANTAEUS
THE GIANT IS INVINCIBLE

AS LONG AS HIS FEET
ARE TOUCHING THE GROUND.

Narrator: HERCULES REALIZES
THE ONLY WAY TO CONQUER ANTAEUS

IS TO LIFT HIM OFF THE GROUND

AND CRUSH HIM
TO DEATH IN MID-AIR.

SO, FOR GENERATIONS, THE LEGENDS
BUILT UP THAT THIS MOUND

WAS THE PLACE WHERE
THE GIANT ANTAEUS WAS BURIED.

Narrator: GOUGH SEES HE'S NOT
THE FIRST TO SHOW AN INTEREST

IN THE MYSTERY MOUND.

IT'S LIKE SOMEONE'S CUT RIGHT
THROUGH THE CENTER OF THE MOUND.

Narrator: GOUGH APPROACHES A MAN
LIVING BY THE SITE,

HOPING TO FIND OUT
WHO'S BEEN DIGGING HERE

AND WHAT, IF ANYTHING,
THEY FOUND.

SHERIF TELLS HIM
A SPANISH ARCHAEOLOGIST

VISITED THE SITE
OVER 80 YEARS AGO.

IN THE 1930s, IT SEEMS,

CéSAR LUIS DE MONTáLBAN
ATTEMPTED TO EXCAVATE THE SITE.

HE NEVER PUBLISHED
WHAT HE FOUND AND NO ONE

SINCE HAS BEEN GIVEN
PERMISSION TO TOUCH THE SITE.

GOUGH STARTS TO ANALYZE
THE NEOLITHIC STONES THEMSELVES.

STONE CIRCLES ARE TYPICALLY
FOUND NOT IN AFRICA,

BUT IN NORTHERN EUROPE,

THE WONDERFUL
AND MYSTERIOUS CREATIONS

OF PREHISTORIC MAN.

ALMOST A THOUSAND OF THEM
ARE IN BRITAIN

AND THEIR PURPOSE HAS SOMETHING
TO DO WITH THE HEAVENS.

Bellinger: THE STONES ARE PLACED
IN SUCH A WAY,

TO COINCIDE WITH
THE MOVEMENT OF THE SUN

ON SPECIFIC SEASONAL DATES
OF IMPORTANCE

SUCH AS THE SUMMER
OR WINTER SOLSTICE.

THIS IS WHAT THEY USED TO TIME
THEIR PLANTING SEASONS.

EVERYBODY KNOWS
WHEN A CROP IS RIPE,

BUT THE TRICKY BIT
IS TO KNOW WHEN TO PLANT IT.

Narrator: GOUGH CHECKS
IF ANY OF THE STONES

ARE ALIGNED TO A POSITION,

WHICH, IN NEOLITHIC TIMES,
WOULD HAVE MARKED

THE RISING OF THE SUN
AT THE SUMMER SOLSTICE.

Gough: OKAY.

IT'S TELLING ME SUNRISE
ON JUNE 20

WOULD BE RIGHT HERE

AND LOOK AT THAT.

Narrator: STONE NUMBER 30 COULD
WELL HAVE BEEN A MARKER STONE,

MAKING THIS A GIANT
ASTRONOMICAL CALENDAR.

Gough: TO ME, THAT'S VALIDATION
OF THE FACT THAT THIS WAS BUILT

WITH THE SAME INTENTION
AS THE BRITISH STONE CIRCLES

AND I THINK THAT
IT REALLY INCREDIBLE.

Narrator: FOR GOUGH, FINDING A
NEOLITHIC STONE CIRCLE IN AFRICA

IS LIKE FINDING
A PYRAMID IN KANSAS.

HE GOES ON TO MEASURE
THE DIAMETER OF THE STRUCTURE.

Gough: OKAY, SO IT'S TELLING ME
THAT'S 160 FEET.

Narrator:
GOUGH REPEATS THE MEASUREMENT

FROM ANOTHER POSITION

AND DISCOVERS
SOMETHING UNEXPECTED.

180 FEET!

IT'S NOT THE SAME
AS THE OTHER AXIS.

Narrator: THIS STONE CIRCLE
ISN'T A CIRCLE AFTER ALL.

IT'S AN OVAL, AN ELLIPSE.

GOUGH BELIEVES
THIS MAKES IT SPECIAL.

THE MOST ANCIENT STONE CIRCLES
ARE AN ELLIPSE LIKE THIS ONE.

Narrator: BRITAIN'S OLDEST
NEOLITHIC STONE RINGS,

STENNESS AND CALLANISH,

ARE BOTH ELLIPTICAL,
BUT THEY'RE MUCH SMALLER.

HERE, IN A REMOTE NEIGHBORHOOD
IN NORTH AFRICA,

COULD BE SITTING THE OLDEST,

LARGEST ELLIPTICAL
STONE STRUCTURE IN EXISTENCE.

PERHAPS THIS IS
WHERE IT ALL BEGAN.

I'M WONDERING, COULD THIS BE
THE SITE WHERE MAN WENT FROM

BEING HUNTER-GATHERERS
TO FARMERS

AND NEEDED TO KNOW WHEN
THE SEASONS CHANGE PRECISELY

SO THEY CAN PLANT THEIR CROPS?

COULD THIS BE THE PLACE
WHERE THAT TECHNOLOGY WAS BORN

AND THEN BROUGHT TO THE U.K.?

Narrator:
BUT SOMETHING DOESN'T FIT.

THE VERY OLDEST BRITISH STONE
CIRCLES ARE LOCATED NEAR WATER,

VITAL IN PREHISTORIC TIMES FOR
TRANSPORTING SUCH HUGE STONES.

WHAT'S MORE, THIS IS MEANT
TO BE THE TOMB OF ANTAEUS,

SON OF POSEIDON, GOD OF WATER.

Gough: BUT I LOOK AROUND.

I DON'T SEE A DROP OF WATER
IN ANY DIRECTION.

Narrator: GOUGH RETURNS TO
THE SATELLITE IMAGE

AND THEN HE SEES SOMETHING.

IT'S NOT A ROAD.
IT LOOKS LIKE A RIVERBED.

IT'S DRIED UP, OF COURSE,
BUT IT'S GOING RIGHT ALONG HERE.

THAT IS DEFINITELY A RIVERBED.

Narrator:
FOR GOUGH, THIS CONFIRMS
THAT BRITISH STONE CIRCLES

MAY HAVE ORIGINATED
HERE IN AFRICA.

IT'S A HIGHLY
CONTROVERSIAL THEORY,

BUT THERE'S SOME SUPPORT FOR IT
IN RECENT GENETIC STUDIES.

Horton: PEOPLE HAVE BEEN
STUDYING ANCIENT DNA

AND HAVE COME
TO THE CONCLUSION

THAT PEOPLE WERE MOVING

MUCH MORE DRAMATICALLY
AND RADICALLY IN THIS PERIOD

THAN WE EVER THOUGHT.

Krueger: WHEN YOU THINK ABOUT
A SITE LIKE STONEHENGE,

YOU THINK OF ONE OF THE OLDEST
CULTURAL SITES IN THE WORLD,

BUT IT'S REALLY REMARKABLE
TO THINK THAT EVEN A SITE

AS OLD AS STONEHENGE
COULD HAVE BEEN INSPIRED

BY SOMETHING IN NORTH AFRICA.

**

Narrator: COMING UP, A GAPING
HOLE THREATENS TO EAT ARIZONA.

THIS FEATURE ISN'T JUST
A LOCAL ANOMALY.

THIS FEATURE IS BIG.

Narrator: AND SINISTER
C.I.A. SECRETS IN THE OUTBACK.

Baker: IT'S A DANGEROUS PLACE
OUT THERE.

WHOEVER HAS MORE INTELLIGENCE
OR MORE INFORMATION

USUALLY WINS.

**

Narrator:
NORTHERN TERRITORY, AUSTRALIA --

WITNESSES REPORT A STRING
OF UNSETTLING SIGHTINGS

IN THE MIDDLE OF THE OUTBACK.

THERE HAVE BEEN REPORTS
OF VERY STRANGE AIRCRAFT

AND DIFFERENT LIGHTS
LIKE BLUE AND GOLD LIGHTS.

SOME SUGGEST THAT IT MIGHT
BE UFO AND ALIEN ACTIVITY.

SO, YOU CAN'T TELL ME NOTHING
WEIRD IS GOING ON HERE.

Narrator:
THESE STRANGE EVENTS APPEAR
TO BE COMING FROM ONE PLACE.

INVESTIGATORS STUDY
SATELLITE IMAGES OF THE AREA.

WHERE THERE SHOULD BE
NOTHING BUT DESERT,

THEY FIND WHAT LOOKS
LIKE A SECURE FACILITY.

Capps:
IT IS THIS MASSIVE FACILITY.

ALL THIS COOL, DEATH STAR-LIKE
DOMES IN THE MIDDLE OF NOWHERE.

THERE'S A BARRIER-FENCE
PROTECTING THE ENTIRE COMPLEX,

SO IT'S ALSO VERY SECRETIVE.

Narrator:
DECLASSIFIED DOCUMENTS REVEAL

THE CLANDESTINE FACILITY
GOES UNDER THE NAME OF PINE GAP.

IT IS BUILT AT THE HEIGHT
OF THE COLD WAR.

THE AUSTRALIAN PUBLIC ARE TOLD
IT'S A SPACE-RESEARCH FACILITY,

BUT IT HOLDS A DARKER SECRET.

THIS IS AN AMERICAN FACILITY
ON AUSTRALIAN TERRITORY,

BUT THERE'S RUMORS TO SUGGEST
THAT EVEN THE AUSTRALIANS

DON'T GET THE FULL PICTURE
OF WHAT'S GOING ON HERE.

Narrator: BEHIND THE SCENES,
THE C.I.A. RUNS THE STATION

TO COLLECT INTELLIGENCE

ON THE SOVIET UNION'S
SECRET MISSILE PROGRAM,

BUT THE FACILITY DOESN'T SHUT
DOWN WHEN THE COLD WAR ENDS.

IT GROWS INTO A VAST COMPLEX.

Pavelec: IN THE LAST 50 YEARS,

IT'S GONE FROM
A COUPLE OF THOUSAND SQUARE FEET

TO A COUPLE OF HUNDRED THOUSAND
SQUARE FEET OF FLOOR SPACE.

THEY'RE EXPANDING THE BUILDINGS,
ADDING ANTENNAS,

MOVING THE EQUIPMENT.

THEY CONTINUE TO POUR MONEY
INTO THE PLACE.

Narrator: ITS PURPOSE TODAY IS
A CLOSELY GUARDED SECRET.

MANY WONDER WHETHER
THERE'S A CONNECTION

TO THE STRANGE LIGHTS
WITNESSED IN THE AREA.

INVESTIGATORS CONSIDER
IF THE PECULIAR WHITE DOMES

PUNCTUATING THE FACILITY
HOLD THE KEY TO WHAT'S GOING ON.

D'Antonio: THESE DOMES HAVE
LITTLE, TINY, FLAT AREAS.

THESE ARE HOW
THESE GEODESIC DOMES ARE BUILT

THAT ARE USED TO COVER
SENSITIVE ELECTRONICS.

THESE GEODESIC DOMES
ARE ACTUALLY CALLED RADOMES.

THEY'RE PROTECTING A MICROWAVE
ANTENNA UNDERNEATH.

Narrator: IN TOTAL, 38
STATE-OF-THE-ART RADAR DISHES

AND DOMES POINT SKYWARD.

THIS SUGGESTS THAT PINE GAP
IS BEING USED

AS A SUPER-POWERFUL
INTELLIGENCE GATHERING STATION.

IT'S A DANGEROUS PLACE OUT THERE

AND, YOU KNOW,
WHOEVER HAS MORE INTELLIGENCE

OR HAS MORE INFORMATION
USUALLY WINS.

D'Antonio: IS IT POSSIBLE
THAT THEY'RE LISTENING

TO EVERYTHING WE'RE SAYING?

I CAN'T SAY "NO" TO THAT BECAUSE
WE KNOW THERE ARE PROGRAMS

LIKE THAT IN PLACE
AROUND THE WORLD.

Narrator:
CLASSIFIED DOCUMENTS LEAKED
BY WHISTLE-BLOWER EDWARD SNOWDEN

CONFIRM THE SITE'S KEY ROLE

IN SUPPORTING
INTELLIGENCE ACTIVITIES,

BUT THEY ALSO REVEAL
THAT THERE'S SOMETHING ELSE

GOING ON AT PINE GAP.

SOME BELIEVE PINE GAP
IS A CONTROL CENTER

FOR U.S. DRONE ATTACKS
WORLDWIDE.

Capps:
IT'S NOT CRAZY AT ALL TO THINK

THAT SOMEONE'S PILOTING
A DRONE FAR FROM THE THEATER

AND WATCHING EXACTLY
WHAT THE DRONE IS DOING,

SEEING THE FOOTAGE
AND MAKING DECISIONS.

Narrator:
BUT NEITHER INTELLIGENCE
GATHERING OR DRONE PILOTING

CAN ACCOUNT FOR
THE STRANGE OBJECTS

REPORTED TO HAVE BEEN SEEN
CLOSE TO THE PINE GAP STATION.

OBSERVERS POINT TO SIMILARITIES
BETWEEN PINE GAP

AND ANOTHER TOP SECRET
U.S. MILITARY SITE.

LIKE PINE GAP, IT'S LOCATED
IN THE MIDDLE OF THE DESERT.

LIKE PINE GAP,
IT'S A HIGH-SECURITY FACILITY

PROTECTED BY A NO-FLY ZONE.

YOU LOOK AT PINE GAP.
IT'S REMOTE, IT'S SECRET.

IT'S LIKE AREA 51.

Narrator: THE MAIN PURPOSE OF
THE HIGH-SECURITY U.S. AIR BASE

KNOWN AS AREA 51 REMAINS
A HIGHLY GUARDED SECRET,

BUT RECORDS SUGGEST IT HAS BEEN,
AMONG OTHER THINGS,

A TEST SITE FOR WEIRD,
EXPERIMENTAL AIRCRAFT.

PEOPLE HAVE SEEN THESE
TRIANGULAR-SHAPED CRAFTS

FLYING AROUND.

Narrator:
BUT WHEN ANALYSTS TAKE A CLOSER

LOOK AT THE SATELLITE
IMAGE OF PINE GAP,

THEY NOTICE
SOMETHING IS MISSING.

D'Antonio:
THERE'S NO RUNWAYS AROUND HERE,

SO ANY OF THE AIRCRAFT
THAT WOULD BE HERE

WOULD JUST HAVE TO
TAKE OFF VERTICALLY,

SORT OF LIKE A HELICOPTER DOES,

BUT THERE'S NO
AIRCRAFT WHATSOEVER.

Narrator: FOR NOW, THE STRANGE
LIGHTS WITNESSED

IN THE AUSTRALIAN OUTBACK
REMAIN UNEXPLAINED.

AND WHAT EXACTLY
GOES ON AT PINE GAP

IS UNLIKELY TO BE
REVEALED ANYTIME SOON.

D'Antonio:
I DON'T HAVE ALL THE ANSWERS.

NO ONE DOES EXCEPT THE PEOPLE
THAT ARE INSIDE THIS COMPLEX

AND THEY'RE NOT TALKING.

SO, FOR NOW, ANYWAY,
WE'RE GOING TO BE OUTSIDE

THE FENCE AROUND PINE GAP.

Narrator:
COMING UP, A MONSTER CRACK

THREATENING
TO TEAR APART ARIZONA.

IF THIS CRACK GROWS, IT COULD
SPLIT THE TOWN IN HALF.

Narrator:
PINAL COUNTY, ARIZONA.

IN APRIL 2016, THE WORLDVIEW-3
SATELLITE PASSES OVER AN AREA

JUST SOUTH OF ARIZONA CITY
AND SPOTS A HUGE CRACK.

IT LOOKS AS IF THE EARTH
HAS JUST OPENED UP AND SPLIT.

Narrator: WHEN SCIENTISTS
MEASURE THE CRACK,

THEY DISCOVER
IT'S OVER TWO MILES LONG.

THIS FEATURE
ISN'T JUST A LOCAL ANOMALY.

THIS FEATURE -- IT'S BIG.

AND THAT PROVIDES
A PRETTY SERIOUS INDICATION

THAT POWERFUL FORCES
ARE AT WORK SOMEWHERE.

Narrator: ANALYST KEN JOYCE
USES DIGITALGLOBE

SECUREWATCH TECHNOLOGY

TO TRY TO FIND OUT
WHAT'S HAPPENING.

Joyce: USING HISTORIC
SATELLITE IMAGERY,

WE CAN FIGURE OUT WHEN
THIS CRACK STARTED TO FORM.

AS I LOOK BACK TO IMAGES
THAT WERE CAPTURED IN 2014,

I DON'T SEE
ANY EVIDENCE OF A CRACK.

SCROLLING FORWARD TO 2016,
BOOM -- THE CRACK APPEARS.

Narrator: EVEN MORE SHOCKING IS
WHAT JOYCE DISCOVERS NEXT.

ARIZONA IS CONTINUING
TO SPLIT OPEN.

THE ALARMING THING IS
IS THAT THE CRACK

CONTINUES TO MAKE ITS WAY NORTH

AND IS NOW ENDANGERING
THIS POPULATED AREA HERE.

Narrator:
INVESTIGATORS NEED TO FIND OUT

WHAT IS CAUSING THE EARTH
TO SPLIT AND FIND OUT QUICK.

AT FIRST, THEY CONSIDER
IF IT COULD BE SEISMIC ACTIVITY.

PROBABLY THE FIRST THING
THAT YOU WOULD THINK OF

IS THAT SOMETHING
GEOLOGICALLY IS HAPPENING,

SOMETHING LIKE AN EARTHQUAKE.

Narrator:
BUT THIS DOESN'T STACK UP.

THERE ARE NO REPORTS
OF EARTHQUAKES HERE,

AND THAT'S NOT ALL.

FOR THE MOST PART,
EARTHQUAKES DON'T MAKE OPENINGS.

EARTHQUAKES MAKE SHAKING.

**

INVESTIGATORS WONDER WHETHER THE
CRACK COULD INSTEAD BE MAN-MADE.

MILITARY HISTORIAN MARTIN MORGAN
IS REMINDED OF A DARK CHAPTER

IN THE HISTORY OF THE U.S. ARMY
FIVE DECADES AGO.

Morgan: IN THE 1960s, THE ARMY
CAME UP WITH THIS BRIGHT IDEA

OF TAKING TOXIC WASTE,
TURNING IT INTO A LIQUID,

AND THEN PUMPING
THIS TOXIC-WASTE WATER

INTO UNDERGROUND CAVITIES.

Narrator: IT ALL STARTS
WITH THE UNEXPECTED ATTACK

ON PEARL HARBOR
THAT PROPELS THE U.S.

INTO WORLD WAR II.

JUST SIX MONTHS LATER,

THE ARMY OPENS A NEW
WEAPONS FACTORY IN COLORADO.

THE ROCKY MOUNTAIN
ARSENAL GOES ON

TO PRODUCE
LETHAL CHEMICAL WEAPONS

INCLUDING SARIN AND MUSTARD GAS.

BUT OVER THE YEARS, IT ALSO
CREATES MILLIONS OF GALLONS

OF TOXIC WASTE THAT IS SIMPLY
DUMPED UNDERGROUND.

THAT DIDN'T WORK OUT SO WELL
BECAUSE IT CAUSED EARTHQUAKES

AND IT CRACKED THE EARTH.

THE CRACK THAT IS SEEN
IN THE IMAGE --

IT LOOKS A LOT LIKE THE
DESCRIPTIONS OF THE CRACKS

THAT APPEARED AFTER THE ARMY

PUMPED TOXIC-WASTE WATER
INTO COLORADO.

Narrator: THERE IS A STRONG
MILITARY PRESENCE IN ARIZONA

WITH SEVEN BASES ACROSS THE
STATE AND INVESTIGATORS CONSIDER

IF THIS MIGHT BE A CLUE
TO THE ORIGIN OF THE CRACK.

BUT WHEN SCIENTISTS VISIT
THE SITE AND TAKE SOIL SAMPLES,

THEY UNCOVER NO EVIDENCE
OF TOXIC CONTAMINATION.

SEARCHING FOR
ANOTHER EXPLANATION,

THEY NOTICE THAT NEARBY
GROUND WATER LEVELS ARE LOW.

Sanford:
ARIZONA IS A VERY DRY PLACE.

FARMERS ARE PUMPING GROUNDWATER
TO IRRIGATE THEIR PLANTS.

Cerveny:
SO, IF YOU START EXTRACTING
LARGE AMOUNTS OF WATER,

YOU'RE GOING TO CREATE
AN EMPTY SPOT

WHERE THAT WATER USED
TO BE UNDERGROUND.

Narrator: GEOLOGISTS NOW BELIEVE
THAT GROWING UNDERGROUND VOIDS

ARE CAUSING THE EARTH'S
SURFACE TO SPLIT OPEN.

Lester: ALL OF A SUDDEN, THE
LANDSCAPE CAN'T HOLD ITSELF UP

AND WHEN THAT HAPPENS,

TWO SUBSIDING LAND MASSES
PULL AWAY FROM EACH OTHER

AND YOU'RE LEFT
WITH THIS GAPING CHASM.

Narrator: WHAT'S WORSE, THIS IS
NOT THE ONLY CHASM IN THE AREA.

SCIENTISTS HAVE NOW MAPPED
170 MORE MILES OF SIMILAR CRACKS

ELSEWHERE IN THE STATE
AND THEY KEEP DISCOVERING MORE.

THE NIGHTMARE SCENARIO
IS THAT A MONSTER CRACK

WILL SWALLOW A TOWN.

IF I WALKED OUT IN MY BACKYARD
AND SAW A CHASM

STRETCHING OFF TO THE HORIZON
THAT WAS TEN FEET WIDE,

I WOULD CALL
THE MOVING COMPANY RIGHT AWAY

AND GET OUT AS FAST AS I COULD.
