THE AMAZON --

OVER TWO MILLION SQUARE MILES

OF FORBIDDING IMPERVIOUS JUNGLE.

SOMEWHERE IN HERE IS BELIEVED
TO LIE A HIDDEN CITY

THAT HAS BEGUILED EXPLORERS
AND ARCHEOLOGISTS

FOR 500 YEARS...

PAITITI.

Man: PAITITI IS A LEGEND
AMONG EXPLORERS.

THIS IS THE LOST CITY OF GOLD
OF THE INCA EMPIRE.

Narrator:
ACCORDING TO HISTORICAL TEXTS,

THE FORTIFIED JUNGLE CITY

CONTAINS A TRULY VAST
HORDE OF TREASURE.

Kourounis: WE'RE TALKING GOLD
AND POSSIBLY JEWELS

TO RIVAL THE CROWN JEWELS OF
ENGLAND AND FORT KNOX COMBINED.

Narrator:
FRENCH EXPLORER THIERRY JAMIN

HAS SPENT 20 YEARS OF HIS LIFE
TRYING TO FIND PAITITI.

HE BELIEVES SATELLITE IMAGES

COULD GIVE HIM
THE BREAKTHROUGH HE NEEDS.

[ JAMIN SPEAKING FRENCH ]

Narrator: PAITITI IS RUMORED
TO LIE IN A REGION

TO THE EAST
OF THE ANDES MOUNTAINS.

IN 2012, AS HE AND HIS TEAM
SCANNED A REMOTE VALLEY IN PERU,

THEY SPOT SOMETHING UNUSUAL
IN THE JUNGLE TOPOGRAPHY.

THE IMAGE REVEALS
A SQUARE FEATURE

PROTRUDING FROM
A 6,000-FOOT-HIGH RIDGE.

[ KEYBOARD CLACKING ]

JAMIN BELIEVES IT COULD BE
THE ARCHEOLOGICAL FOOTPRINT

OF A LARGE FORTIFIED CITY

WHICH HAS BEEN DEVOURED
BY THE RAINFOREST.

Stenstrom: THAT GREEN SQUARE
IN THE MIDDLE OF THE FOREST

COULD CONCEAL ONE THE BIGGEST
TREASURES WE'VE EVER FOUND.

Narrator: JAMIN IS PREPARING
TO TREK TO THE ISOLATED LOCATION

FROM THE ANDEAN TOWN OF CUSCO.

IT WILL TAKE A PARTY OF 18
TO BATTLE THROUGH THE JUNGLE,

A BRUTAL JOURNEY
THAT WILL TAKE WEEKS.

**

BESIDES THE NATURAL PERILS,
THIS MOUNTAINOUS JUNGLE

ALSO HIDES ILLEGAL LOGGERS
AND COCAINE TRAFFICKERS.

TRYING TO GET TO THIS LOCATION
IS THE REAL DEAL

WHEN IT COMES TO EXPLORATION.

Stenstrom:
IT IS SO FAR FROM CIVILIZATION.

THERE'S NO SAFETY NET,
AND IF YOU STUMBLE, YOU'LL DIE.

**

Narrator:
THE FIRST LEG IS EASY --

240 MILES BY ROAD
TO THE SMALL PORT OF IVOCHOTE.

BUT THEN FOR ALMOST 100 MILES,
IT'S A TANGLED MASS

OF HOSTILE,
TRACKLESS, DEADLY JUNGLE.

[ CONVERSING
IN NATIVE LANGUAGE ]

JAMIN MUST RELY ON
THE TRACKING SKILLS

OF THE LOCAL
MATSIGENKA TRIBESMEN

WHOSE SURVIVAL SKILLS
AND KNOWLEDGE OF THE AMAZON

IS UNSURPASSED.

**

FOR JAMIN, THE MATSIGENKA'S
ORAL HISTORIES

PROVIDE CONFIRMATION

THAT HE'S LOOKING
IN THE RIGHT PLACE

FOR THE LOST CITY OF GOLD.

Stenstrom: THE LEGEND SAYS THAT
THE CITY OF PAITITI IS FOUND

BY A SQUARE MOUNTAIN NEXT TO
A SQUARE LAGOON AND TWIN LAKES,

AND WHAT DO WE SEE
IN THIS PICTURE?

THAT'S IT.

Narrator: THE SQUARE MOUNTAIN
SITS INSIDE THE VAST AREA

ONCE CONTROLLED BY THE INCA.

IN THE 15th CENTURY,
ITS POPULATION OF 16 MILLION

WAS THE LARGEST IN THE WORLD,
AMASSING VAST WEALTH.

Hunt: THE INCAS HAD MORE GOLD
AND SILVER

THAN ALMOST ANY OTHER
CULTURE ON RECORD,

BECAUSE THEY LIVED
IN THE ANDES MOUNTAINS,

VOLCANIC IGNEOUS MOUNTAINS
THAT WERE REALLY RICH IN GOLD.

Narrator: IN THE YEARS FOLLOWING
THE ARRIVAL OF THE SPANISH

IN THE EARLY 16th CENTURY,

CONQUISTADORS PLUNDER
$17 BILLION

OF INCAN GOLD AND SILVER.

[ MEN SHOUTING,
WEAPONS CLANGING ]

THE INCAS HIDE WHAT THEY CAN
OF THEIR TREASURE.

AND IN THE LAND OF THE INCAS,

THE GREATEST FORTRESS OF ALL
IS THE JUNGLE.

**

**

JUST THREE DAYS INTO THEIR TREK,
AND JAMIN AND THE TEAM

ARE ENCOUNTERING THE SAME
LIFE-THREATENING TERRAIN

AND CONDITIONS THAT THWARTED
THE CONQUISTADORS' ATTEMPTS

TO FIND PAITITI
CENTURIES EARLIER.

POURING RAIN,
VERY SLIPPERY SLOPES,

RUSHING STREAMS AND RIVERS

THAT CONFOUND THE EFFORTS
OF THE MOST TENACIOUS EXPLORERS.

Narrator:
THERE IS DOCUMENTARY EVIDENCE

TO SUPPORT THE EXISTENCE
OF THIS CITY OF GOLD.

IN 2001, AN ITALIAN ARCHEOLOGIST
DISCOVERED A MANUSCRIPT

IN THE VATICAN ARCHIVES

WHICH DATES BACK
TO THE CONQUISTADORS.

Kourounis: IN 1600, ONE OF THE
MISSIONARIES IN SOUTH AMERICA

BROUGHT A LETTER
BACK TO THE POPE,

AND IT TOLD TALE
OF THIS VAST CITY OF GOLD.

Narrator:
ACCORDING TO THE MANUSCRIPT,

THE CITY OF GOLD LIES IN DEEP
JUNGLE NORTHEAST OF CUSCO,

ROUGHLY THE SAME POSITION
AS THE RAISED SQUARE FEATURE

IN THE SATELLITE IMAGE.

JAMIN AND HIS TEAM ARE SIX DAYS
INTO THEIR TREK

WHEN THEY HIT THEIR FIRST
MAJOR SETBACK --

A SWOLLEN RIVER
THAT THREATENS TO SWEEP AWAY

HIS SUPPLIES AND HIS MEN.

[ MONTES SPEAKING SPANISH ]

Narrator:
THE ENFORCED 15-MILE DIVERSION

ADDS SEVERAL COSTLY DAYS
TO THE TEAM'S JOURNEY.

WORSE STILL, IT MEANS
THEY'RE EATING INTO

THEIR PRECIOUS SUPPLIES.

Wallace: THE JUNGLE IS LITTERED
WITH THE REMNANTS

OF FAILED EXPEDITIONS.

IT'S AN EASY PLACE
TO LOSE YOUR WAY

AND, SOME WOULD SAY,
TO LOSE YOUR MIND.

Narrator:
12 DAYS INTO THEIR EXPEDITION,

AND THEIR LUCK TURNS
FOR THE BETTER.

THEN, THROUGH A BREAK
IN THE TREES,

JAMIN CATCHES THE FIRST
GLIMPSE OF HIS PRIZE.

GPS DATA CONFIRMS THAT THIS IS
THE RAISED SQUARE FEATURE

IN THE SATELLITE IMAGE.

**

COULD YOU IMAGINE IF
THIS TURNS OUT TO BE PAITITI?

Narrator: COMING UP...

CAPTURED BY SATELLITE, CHINA'S
MYSTERY MILITARY STRONGHOLDS.

WHAT A MOATED ISLAND IS DOING
IN THE MIDDLE THE GOBI DESERT --

IT'S A MYSTERY.

Narrator:
AND EXPLORER THIERRY JAMIN

DISCOVERS THE CURSE OF PAITITI.

Hunt: THIS ISN'T A GAME.

PEOPLE DIE.

**

**

Narrator:
FRENCH EXPLORER THIERRY JAMIN

IS DEEP IN THE AMAZON JUNGLE...

14 DAYS INTO AN EXPEDITION
TO REACH A SQUARE MOUNTAIN

CAPTURED IN A SATELLITE IMAGE,

THE SITE, HE BELIEVES,

OF THE LEGENDARY
LOST CITY OF GOLD -- PAITITI.

BUT PROGRESS HAS BEEN
PAINFULLY SLOW,

AND SUPPLIES ARE RUNNING OUT.

INDIGENOUS AMAZONIAN PEOPLE
ARE PERMITTED TO CATCH

AND EAT WILDLIFE
WITHIN THE FOREST,

BUT HUNTING FOR FOOD TAKES TIME
AND IS UNRELIABLE.

AN EVEN BIGGER WORRY
IS A SUPPLY OF DRINKABLE,

UNCONTAMINATED WATER.

[ INSECTS BUZZING ]

**

JAMIN NOW KNOWS HE AND HIS TEAM
RISK THE SAME FATE

AS HUNDREDS OF EXPLORERS
BEFORE THEM.

THE MOST FAMOUS
WAS THE ENGLISH ADVENTURER

COLONEL PERCY FAWCETT.

AFTER A FINAL LETTER TO HIS WIFE
FROM DEEP IN THE AMAZON

ON MAY 29, 1925,
FAWCETT DISAPPEARS.

HIS BODY IS NEVER RECOVERED.

SOME HISTORIANS SPECULATE
THAT HE RUNS OUT OF SUPPLIES

AND STARVES TO DEATH.

THIS ISN'T A GAME.

PEOPLE DIE.

PEOPLE SIMPLY ARE
NEVER HEARD OF AGAIN.

Narrator: FOR SOME IN THE TEAM,
THERE ARE OTHER DANGERS AHEAD,

NOT ALL OF THEM NATURAL.

JAMIN'S TEAM LEADER
IS EX-SOLDIER JOSé MONTES.

[ BIRDS CHIRPING ]

WHEN MONTES REPORTS WHAT HE'S
SEEN TO THE MATSIGENKA GUIDES,

THEY REVEAL THAT MANY MEMBERS
OF THEIR TRIBE

AVOID THESE MOUNTAINS,

BELIEVING THEM TO BE
INHABITED BY THE DEVIL.

[ SPEAKING
NATIVE LANGUAGE ]

ACCORDING TO LEGEND,

PAITITI IS INHABITED
BY SUPERNATURAL BEINGS,

ITS GATES GUARDED BY GIANT
DOUBLE-HEADED SERPENTS

KNOWN AS THE AMARU.

**

THE TEAM HAS BEEN LABORING
THROUGH THE JUNGLE

FOR 2 1/2 WEEKS.

THEY ARE EKING OUT
THEIR SUPPLIES AS BEST THEY CAN,

BUT THE VEGETATION
IS GROWING MORE DENSE,

INFESTED WITH SNAKES
AND INSECTS.

[ INSECTS BUZZING ]

AND JUST 15 MILES FROM THE BASE
OF THE SQUARE MOUNTAIN,

A TORRENTIAL DELUGE
FLOODS THE AREA.

PROGRESS IS IMPOSSIBLE.

THE RAINSTORM FORCES
THE TEAM TO CONSUME

ALMOST ALL OF WHAT'S LEFT
OF THEIR PROVISIONS.

IT DRIVES WILDLIFE INTO HIDING,

PREVENTING THE GUIDES
FROM HUNTING FOR MORE FOOD.

[ THUNDER CRASHES ]

JAMIN SEES THAT HE IS PUTTING
THE LIVES OF HIS TEAM IN DANGER.

HIS HAS NO CHOICE BUT TO
ABANDON THE EXPEDITION.

**

EVEN FOR JAMIN, AN EXPLORER
WITH 20 YEARS' EXPERIENCE,

THE FORMIDABLE AMAZON HAS PROVED
TO BE A TOUGHER ADVERSARY

THAN HE ANTICIPATED.

THE LATEST QUEST TO FIND
AND REACH PAITITI

HAS ENDED IN FAILURE.

BUT JAMIN MAY BE THE FIRST
PERSON IN HISTORY

TO HAVE GLIMPSED THE FABLED CITY
AND LIVED TO TELL THE TALE.

IT HAS REAFFIRMED HIS BELIEF
THAT THIS SATELLITE IMAGE

IS THE KEY TO SOLVING
THE 500-YEAR-OLD MYSTERY.

Kourounis: THIS SATELLITE IMAGE
IS ABSOLUTELY COMPELLING,

BUT UNTIL THIERRY OR SOME
OTHER INTREPID EXPLORER

ACTUALLY SETS FOOT ON THE SITE
AND SEES WITH THEIR OWN EYES,

WE'LL NEVER KNOW IF THIS IS
THE LOST CITY OF PAITITI.

**

Narrator: COMING UP --
A MAGNETIC MARTIAN MOUNTAIN

ADVANCING ACROSS PLANET EARTH...

IT'S EXTREMELY STRANGE --

MOVING CONSTANTLY
BUT NEVER SEPARATING.

Narrator:
...AND 25 MILLION PEOPLE DEAD.

WHAT'S THE CONNECTION
WITH THIS MYSTERY MOAT?

PEOPLE COULDN'T ESCAPE
TO ANYWHERE EXCEPT DEATH.

**

**

Narrator: MARCH 6, 2017.

AN EARTH-OBSERVATION SATELLITE

PASSES OVER CHINA'S
500,000-SQUARE-MILE GOBI DESERT.

IN A REMOTE CORNER
OF THE FEATURELESS LANDSCAPE,

IT CAPTURES AN UNUSUAL IMAGE.

Pepper: THERE'S NOTHING
FOR MILES AND MILES,

AND THEN ALL OF A SUDDEN,
YOU SEE THIS DARK RING.

**

Narrator: ZOOMING IN,

INVESTIGATORS DISCOVER
IT'S A RING OF WATER

SURROUNDING
AN ELEVATED STRUCTURE.

Maca:
IT'S A REALLY WEIRD IMAGE

BECAUSE IT'S ONE OF THE DRIEST
PLACES ON EARTH,

AND THERE'S WATER HERE.

THERE'S WATER IN THE MIDDLE
OF THE DESERT.

WHAT A MOATED ISLAND IS DOING IN
THE MIDDLE OF THE GOBI DESERT --

IT'S A MYSTERY.

Narrator: SCALE ANALYSIS REVEALS
THE MOAT IS HALF A MILE LONG.

THIS CLEARLY LOOKS LIKE
SOME MASSIVE DEFENSIVE FEATURE.

YOU EVEN HAVE AN ACCESS WAY --

A SINGLE ACCESS WAY
TO THE INTERIOR.

Mosher:
MOATS WERE PROTECTIVE DEVICES
FOR ANCIENT CIVILIZATION,

SO MAYBE THERE'S EVIDENCE
OF AN ANCIENT SETTLEMENT.

Narrator: IF THIS IS SOME KIND
OF ANCIENT FORT,

A CLUE TO WHO BUILT IT COULD LIE
JUST 30 MILES TO THE NORTH.

THESE ARE THE REMAINS
OF A FORTIFIED SETTLEMENT

KNOWN AS KHARA-KHOTO,
OR THE BLACK CITY.

KHARA-KHOTO WAS OCCUPIED
BY A GROUP CALLED THE TANGUTS

IN THE 11th AND 12th CENTURIES.

Narrator:
THE LAND OF THE TANGUTS

IS THE GATEWAY
TO THE FAMOUS SILK ROAD.

IT MAKES THEM RICH
BUT ALSO A TEMPTING TARGET.

THEY BUILD FORTIFIED OUTPOSTS
TO PROTECT THEIR CITIES.

**

BUT IMAGE ANALYST MARC D'ANTONIO

BELIEVES THE STRUCTURE
CAPTURED BY SATELLITE IMAGE

ISN'T ONE OF THEM.

D'Antonio: IF I ZOOM IN TO THESE
BUILDINGS HERE ON THE ISLAND,

YOU SEE THAT THEY SEEM TO BE
VERY LIKELY MODERN CONSTRUCTION,

AS IN SOMETIME
IN THE 20th CENTURY

THESE WERE PROBABLY BUILT.

Narrator:
THIS 20th-CENTURY TIMEFRAME

AND THE STRUCTURE'S
REMOTE DESERT LOCATION

LEADS MILITARY ANALYST
MIKE PAVELEC TO CONSIDER

IF THE MOATED FORMATION

IS CONNECTED TO CHINA'S
BRUTAL MAOIST PAST.

Pavelec:
DESERTS ARE TRADITIONALLY USED

BY MILITARIES AND GOVERNMENTS

TO PUT THINGS THAT
YOU DON'T WANT PEOPLE TO SEE.

Narrator:
INTELLIGENCE ANALYSTS CALCULATE

THAT CHINA'S VAST INTERIOR HIDES

OVER 1,000 SECRET
PRISON LABOR CAMPS,

MANY DATING BACK
ALMOST 70 YEARS,

SOME STILL IN USE TODAY.

Pavelec: SO MAYBE IT'S A CHINESE
POLITICAL PRISON,

BECAUSE IT'S SO ISOLATED

AND THEY COULD BE CONTROLLED
AND CAPTIVE.

THAT WOULD EXPLAIN
WHY WE HAVE A MOAT HERE,

BECAUSE MAYBE THIS WAS
A PRISON ISLAND.

[ INDISTINCT SHOUTING ]

Narrator:
CHINA'S FIRST PRISON CAMPS

ARE ESTABLISHED IN THE 1950s
BY COMMUNIST CHAIRMAN MAO ZEDONG

AS HE RUTHLESSLY PURGES
THE COUNTRY OF ANYONE

WHO DARES TO DISAGREE WITH HIM.

DURING HIS 27-YEAR RULE,

AN ESTIMATED 100 MILLION MEN,
WOMEN, AND CHILDREN

ARE INCARCERATED
IN VAST LABOR CAMPS.

Harrison: THEY WERE SUPPOSED TO
LEARN THE ESSENCE OF COMMUNISM

AND WORKING WITH THEIR HANDS

AND BEING,
YOU KNOW, WITH THE PEOPLE.

Narrator: IN MAO'S CAMPS,

PRISONERS ARE SENTENCED
TO HARD LABOR --

12 HOURS A DAY,

OFTEN FOR DECADES ON END
IN BRUTAL CONDITIONS.

MANY STARVE TO DEATH.

THOSE WHO SURVIVE DO SO
BY RESORTING TO THE UNTHINKABLE.

Pepper: PRISONERS ATE WORMS,
RATS, EVEN HUMAN WASTE.

SOME OF THEM RESORTED
TO CANNIBALISM.

PEOPLE COULDN'T ESCAPE
TO ANYWHERE EXCEPT DEATH.

Narrator: MAO'S LABOR CAMPS
CLAIM OVER 25 MILLION LIVES,

DOUBLE THE NUMBER OF CIVILIANS
KILLED BY HITLER'S REGIME.

BUT WHEN MARC D'ANTONIO
RE-ANALYZES THE IMAGE,

HE FINDS EVIDENCE TO SUGGEST THE
MOAT IS NOT TO KEEP PEOPLE IN,

BUT TO KEEP ENEMIES OUT.

D'Antonio: WHEN WE LOOK AT
THIS IMAGE REAL CLOSE,

WE SEE THAT THERE'S TWO ROUND
OBJECTS AT THE TOP OF THE HILL.

IF THESE ARE GUN EMPLACEMENTS,

THERE'S VALUE TO THIS BEING
A FORTIFIED EMPLACEMENT,

BECAUSE THESE GUNS
CAN HIT TARGETS OUT HERE.

IF YOU ZOOM OUT
A LITTLE BIT MORE,

YOU FIND THESE FOUR TRIANGLES,

AND WE CAN ACTUALLY SEE THAT
THESE HAD TRENCH LINES IN THERE.

Narrator: AND THIS IS NOT
THE ONLY FEATURE OF ITS KIND.

WHEN ANALYSTS SCAN SATELLITE
IMAGES OF THE REGION,

THEY DISCOVER EIGHT MORE
SIMILAR STRUCTURES.

MOST ARE LOCATED WITHIN
75 MILES OF CHINA'S BORDER

WITH NEIGHBORING MONGOLIA,
A HISTORICAL ALLY OF RUSSIA.

HISTORIANS BELIEVE THIS GIVES
A CLUE TO THEIR PURPOSE.

PERHAPS THIS WAS PART OF
CHINA'S BORDER FACILITATES

IN ITS CONFLICT
AGAINST THE SOVIET UNION.

**

[ APPLAUSE ]

Narrator: THE SOVIET UNION
AND CHINA

ARE THE TWO GREAT
COMMUNIST POWERS

OF THE COLD WAR ERA.

BUT FAR FROM BEING CLOSE ALLIES,

THEY HOLD EACH OTHER
IN DEEP MISTRUST.

Pavelec:
IT'S AN INCIDENT THAT'S VERY
OFTEN FORGOTTEN IN THE WEST,

BUT IN THE LATE '60s,
THE WORLD WAS ON THE EDGE

OF NUCLEAR HOLOCAUST.

THE CHINESE AND THE SOVIETS
ALMOST CAME TO NUCLEAR WAR.

Narrator:
THE COMMUNIST POWERS WERE
IMPERIAL MILITARY DICTATORSHIPS

COMPETING AGGRESSIVELY FOR
TERRITORY AND INFLUENCE

OVER SUBJECT STATES.

Harrison: THESE DIVISIONS BEGAN
UNDER STALIN AND MAO.

NO SURPRISE -- THEY BOTH
WANTED POWER FOR THEMSELVES.

THEY BOTH WANTED TO BE
THE LEADER

OF THE INTERNATIONAL
COMMUNIST MOVEMENT.

**

Narrator: RELATIONS BETWEEN
THE COMMUNIST SUPERPOWERS

DETERIORATE FURTHER
WHEN STALIN DIES IN 1953.

Harrison: MAO WAS VERY CRITICAL

WHEN STALIN'S SUCCESSOR,
KHRUSCHCHEV,

STARTED NEGOTIATING
WITH THE UNITED STATES.

MAO THOUGHT, YOU KNOW,
"THIS IS OUTRAGEOUS.

YOU'RE NEGOTIATING
WITH THE ENEMY."

Narrator: DECLASSIFIED
CIA DOCUMENTS

REVEAL THAT BOTH SIDES INCREASE

THEIR MILITARY PRESENCE
IN BORDER REGIONS

LIKE THE ONE
IN THE SATELLITE IMAGE,

INSTALLING THOUSANDS
OF NUCLEAR WEAPONS.

**

Mosher: AN OUTPOST LIKE THIS

WOULD HAVE BEEN
A VERY ADVANTAGEOUS PLACE

TO SUPPLY YOU AS YOU GO
TO THE FRONT LINES.

Narrator:
BUT THIS COMMUNIST COLD WAR
ENDED ALMOST 50 YEARS AGO.

THE WATER IN THE MOAT
LOOKS FRESH.

COULD THIS MEAN THE FORTS
ARE ONCE AGAIN

UNDER ACTIVE MILITARY COMMAND?

Pepper: CHINA'S KNOWN
FOR ITS SECRECY,

SO YOU'VE GOT TO WONDER
WHAT'S GOING ON HERE.

IT LOOKS ALMOST LIKE CHINA'S
GEARING UP FOR SOMETHING.

**

Narrator: COMING UP --
NAZIS, MUMMIES,

AND THE HUNT FOR
CLEOPATRA'S JEWELS...

WE HAVE TO ASK THE QUESTION
"WHO'S DOING THE DIGGING,

AND WHAT WERE
THEY LOOKING FOR?"

Narrator: ...AND INVESTIGATING
THE UNSTOPPABLE BLACK BLOB.

IT MAY END UP IN SOME NEARBY
TOWN OR CITY EVENTUALLY.

**

Narrator: JULY 11, 2014.

THE GeoEye-1 SATELLITE
FLIES OVER TANZANIA

AT OVER 17,000 MILES PER HOUR.

AS IT PASSES HIGH ABOVE
THE SERENGETI GRASSLANDS,

IT CAPTURES A STRANGE BLACK MASS
IN THE LANDSCAPE BELOW.

WELL, THIS THING IS BIG -- ABOUT
80 FEET WIDE AND 200 FEET LONG.

IT'S THE ONLY THING OF THIS
COLOR ANYWHERE AROUND FOR MILES,

AND IT JUST DOESN'T MAKE SENSE.

Narrator: WHEN GEOLOGIST
JESS PHOENIX STUDIES THE IMAGE,

SHE REALIZES SHE HAS SEEN
SOMETHING LIKE THIS BEFORE,

JUST NOT ON OUR PLANET.

SO, THIS IMAGE MAKES ME THINK OF
SOMETHING THAT WE SEE ON MARS.

**

Narrator: THE STRUCTURES ARE
CURVED MOUNDS OF MARTIAN SAND,

KNOWN AS BARCHAN DUNES.

THE BARCHAN SHAPE IS A CRESCENT,

AND IT'S GOT TWO HORNS OR ARMS
THAT EXTEND,

ONE ON EITHER SIDE.

Narrator: ON THE RED PLANET,
BARCHAN DUNES CLUSTER IN FIELDS

OVER 600 MILES LONG,

AND THAT'S WHAT MAKES THE
LONE STRUCTURE IN THE IMAGE

ALL THE MORE MYSTERIOUS.

Phoenix: THIS IS DIFFERENT
THAN WHAT WE SEE ON MARS,

BECAUSE IT'S NOT A SERIES.

THIS IS JUST ONE.

THAT IN AND OF ITSELF
IS PRETTY INTERESTING.

**

Narrator: PHOENIX IS INTRIGUED
BY THE MARTIAN MOUND,

AND TRAVELS TO TANZANIA TO SEE
IF SHE CAN UNCOVER CLUES

AS TO HOW IT COULD HAVE FORMED.

I'M REALLY RACKING MY BRAIN
TRYING TO COME UP

WITH AN EXPLANATION.

MAYBE IT'S MANMADE.

Narrator: THE SATELLITE IMAGE
WAS TAKEN OVER THE OLDUVAI GORGE

WHERE THE FIRST HUMANS
ARE THOUGHT TO HAVE EVOLVED

ALMOST TWO MILLION YEARS AGO.

Bellinger: WE CALL THIS SITE
THE CRADLE OF HUMANITY

BECAUSE OF THE INTENSE DIVERSITY

AND THE SHEER DENSITY OF FOSSILS

AND OTHER MATERIAL REMAINS

THAT WE HAVE OF OUR
EARLIEST HUMAN ANCESTORS.

Narrator: DESPITE EXTENSIVE
EXCAVATIONS HERE,

ARCHEOLOGISTS HAVE FOUND
NO EVIDENCE TO SUGGEST

EARLY MAN BUILT
GIANT MOUNDS LIKE THIS ONE.

**

Phoenix: WOW.

THAT IS REALLY DARK.

AND IT'S --
IT'S PRETTY BIG, TOO.

HMM.

Narrator: UP CLOSE,
PHOENIX CONFIRMS THE STRUCTURE

IS NO MANMADE MOUNT,

BUT A GIANT BLACK DUNE SHAPED
MUCH LIKE THE ONES ON MARS.

**

BUT THEN SHE SPOTS
SOMETHING TRULY BIZARRE.

THERE IS A TRAIL OR SCAR

STRETCHING FROM THE HILL
OVER THE HORIZON.

THIS THING'S ON THE MOVE.

IT'S ALMOST LIKE IT'S ALIVE.

AS IT'S MOVED ACROSS THIS PLAIN,

IT'S JUST COMPLETELY DEMOLISHED

EVERYTHING THAT'S
STANDING IN ITS WAY.

Narrator: HISTORICAL IMAGES
REVEAL THAT EVERY YEAR,

THE DUNE MOVES AROUND 100 FEET
ACROSS THE SERENGETI.

IT'S EXTREMELY STRANGE, BECAUSE
WE HAVE THIS SINGLE PILE OF SAND

MOVING CONSTANTLY
BUT NEVER SEPARATING.

**

Narrator: PHOENIX STUDIES
THE DUNE FOR CLUES

TO EXPLAIN ITS MOVEMENT.

SO, WE HAVE A REALLY BIG
ANGLE CHANGE RIGHT HERE.

SO THAT MEANS THE WIND IS ONLY
BUFFETING THIS THING

FROM ONE SIDE.

THE WIND COMES ACROSS
AND PUSHES THE MATERIAL UP,

AND THEN WHEN IT REACHES
A CERTAIN POINT, IT FALLS DOWN.

Narrator: METEOROLOGICAL DATA
REVEALS THAT THE WINDS HERE

ALMOST ALWAYS BLOW
FROM THE EAST.

THIS EXPLAINS THE DUNE'S
INEXORABLE JOURNEY

WESTWARD ACROSS THE LANDSCAPE

BUT NOT ITS STRANGE BLACK COLOR
OR WHY IT RETAINS ITS SHAPE.

**

PHOENIX CONSIDERS IF THE ANSWER
LIES IN THE DUNE'S GEOLOGY.

THIS STUFF IS PEBBLES,
THIS IS A VERY FINE SAND,

SO WE'VE GOT A BIG JUMP
IN TEXTURE HERE.

USUALLY YOU SEE THIS SORT OF
FINE SAND IN VOLCANIC ASH.

Narrator:
PHOENIX'S ANALYSIS SUGGESTS
THAT THE WEIRD MOVING DUNE

WASN'T FORMED FROM ROCKS
AND SAND ON THIS BARREN PLAIN.

IT WAS SPEWED OUT OF A VOLCANO.

**

Phoenix:
VOLCANOS PRODUCE ASH THAT IS

REALLY RICH IN IRON
AND MANGANESE.

Narrator: THIS HILL IS WEIRD
AND GETS WEIRDER

STILL WHEN PHOENIX
APPROACHES IT WITH A MAGNET.

Phoenix: OH, LOOK, YOU CAN SEE
THE GRAINS JUMPING RIGHT NOW.

THAT IS STRONGLY MAGNETIC.

THE GRAINS, THE INDIVIDUAL
GRAINS, ARE EACH MAGNETIZED.

THAT'S WHAT KEEPING THIS SAND
IN ONE BIG DUNE

AS IT MOVES ACROSS
THE FLOOR OF THIS VALLEY.

**

AND LOOKING AGAIN
AT THE SATELLITE IMAGE,

"WHERE DID IT COME FROM?"

IS MY NEXT QUESTION.

Narrator: PHOENIX SPOTS
A VOLCANO ON THE SATELLITE IMAGE

AND FOLLOWS THE TRAIL
50 MILES EAST TO ITS FOOT.

**

THE ENTIRE AREA IS COVERED IN
THE SAME FINE MAGNETIC MATERIAL

SHE SAW AT THE BLACK DUNE.

Phoenix: WE HAVE MAGNETISM.

Narrator: PHOENIX CAN'T TAKE
SAMPLES FROM THE CALDERA,

AS THE VOLCANO IS ACTIVE.

BUT SHE BELIEVES
THE MOVING MOUND

ORIGINATED IN AN IRON-RICH CLOUD
OF SUPER-HEATED ASH

FROM ONE OF ITS
HISTORIC ERUPTIONS.

Phoenix: AND THE WIND WOULD HAVE
CARRIED THE ASH

AND THOSE HEAVY MINERALS
AND DEPOSITED THEM THERE

ON THE PLAIN WHERE
IT ALL CLUMPED TOGETHER.

**

Narrator: JUST WHICH ERUPTION
CREATED THE STRANGE DUNE

AND WHY THERE IS
ONLY ONE OF THEM

CRAWLING ACROSS THE SERENGETI
REMAINS A MYSTERY.

**

WHATEVER THE ANSWERS,
THIS MOVING MARTIAN MOUND

APPEARS TO BE UNSTOPPABLE.

WE DON'T KNOW HOW LONG IT WILL
CONTINUE TO MOVE FORWARD.

IT MAY END UP IN SOME NEARBY
TOWN OR CITY EVENTUALLY.

**

Narrator: COMING UP...

CAPTURED BY SATELLITE --

A TOXIC PLUME THAT
SCIENTISTS CAN'T EXPLAIN...

Carter:
PEOPLE NEED ANSWERS, RIGHT?

YOU DON'T JUST BECOME
SICK FOR NOTHING.

Narrator: ...AND DIGGING
INTO THE MOUNTAIN

OF THE DEAD.

YOU WOULD HAVE MET YOUR DEMISE

AND BE TRAPPED IN SOME
TYPE OF DUSTY TOMB.

**

Narrator: DECEMBER, 2012.

THE GeoEye-1 SATELLITE PASSES
OVER EGYPT'S

2,500-SQUARE-MILE
WESTERN DESERT.

IT CAPTURES A SMALL OASIS TOWN
CALLED SIWA AND IN ITS CENTER,

WHAT LOOKS LIKE
A POCKMARKED HILL.

Rose: WHAT I'M SEEING IN
THIS PICTURE IS A MOUNTAIN

OF SOME KIND ABSOLUTELY
RIDDLED WITH HOLES,

LIKE SWISS CHEESE.

Sanford: THIS LOOKS LIKE
A TERMITE MOUND,

BUT WHAT WE'RE LOOKING AT
IS ABSOLUTELY MASSIVE.

Narrator: AT FIRST,
MILITARY ANALYSTS BELIEVE

ITS LOCATION IS THE CLUE

TO WHAT MADE THE HOLES
IN THE MOUNTAIN.

**

DURING WORLD WAR II,
THIS AREA WAS CONTESTED

BY THE BRITISH AND GERMANS.

FIRE!

Narrator: FROM 1940 TO 1943,

A BLOODY BATTLE
IS FOUGHT BETWEEN ALLIED

AND AXIS FORCES FOR CONTROL
OF NORTH AFRICA.

**

SIWA'S DESERT OASIS BECOMES
STRATEGICALLY CRITICAL,

OFFERING WATER AND RESPITE

FOR SOME OF THE ALLIES'
ELITE FIGHTING FORCES.

THE LONG RANGE DESERT GROUP
WERE BASED THERE.

THEY WERE THE FORERUNNER
TO THE FAMOUS S.A.S.

OF COURSE, THAT MADE IT
A VERY ATTRACTIVE TARGET

TO THE AXIS FORCES.

Narrator: UNDER THE COMMAND
OF FIELD MARSHALL ERWIN ROMMEL,

GERMAN AND ITALIAN TROOPS
TARGET SIWA.

Morgan: DURING 1942,
THE ITALIAN AIR FORCE

CARRIED OUT A BOMBING ATTACK
ON THE AREA

THAT RESULTED IN THE DEATHS
OF A LARGE NUMBER OF PEOPLE.

**

Narrator: INVESTIGATORS WONDER

IF THE STRANGE MARKINGS
ON THE MOUND

ARE THE RESULT OF
INTENSIVE BOMB DAMAGE.

BUT IMAGE ANALYST MARC D'ANTONIO
IS NOT CONVINCED.

THAT WOULD HAVE TO BE ONE
PRETTY PRECISION STRIKE,

BECAUSE ALL THE CRATERS
ARE IN ONE LOCATION.

Narrator: CLOSER INVESTIGATION
REVEALS THAT THE LOCALS

FEAR THE MOUNTAIN,

WHICH THEY CONSIDER SACRED.

**

INVESTIGATORS NOTICE THE HOLES
ARE OF A SIMILAR SHAPE AND SIZE.

THEY DO NOT LOOK NATURAL.

SO, IF THIS IS EVIDENCE
OF EXCAVATION,

WE HAVE TO ASK THE QUESTION,

"WHO'S DOING THE DIGGING,
AND WHAT WERE THEY LOOKING FOR?"

**

Narrator: ANCIENT TEXTS REVEAL
THAT DURING THE ROMAN ERA,

EGYPT IS A MAJOR EXPORTER
OF PRECIOUS STONES.

Chamberlain: EGYPT WAS ONE OF
THE VERY FIRST COUNTRIES

TO DO GEM MINING
ON A MAJOR SCALE.

Narrator: THE JEWEL
THAT MOST CAPTIVATED

QUEEN CLEOPATRA WAS THE EMERALD.

**

THOUSANDS OF HER GEMS
COME FROM A GREAT MINE

ON THE EASTERN SHORES OF EGYPT.

ANALYSTS NOTICE THAT
THE NARROW SHAFT ENTRANCES

AT CLEOPATRA'S MINES BARE
A STRIKING RESEMBLANCE

TO THE HOLES BURROWED
INTO THE STRANGE MOUND

IN THE SATELLITE IMAGE.

MINING IS NOT FOR
THE FAINT OF HEART.

THESE MINERS MAKE TUNNELS
THAT ARE BARELY BIG ENOUGH

FOR THEMSELVES TO FIT INTO.

IF THERE WAS SOME TYPE
OF A COLLAPSE,

YOU WOULD HAVE MET YOUR DEMISE

AND BE TRAPPED IN SOME
TYPE OF DUSTY TOMB.

Narrator: BUT ARCHEOLOGIST
JEFF ROSE'S ANALYSIS

OF SIWA'S GEOLOGY

SUGGESTS THE STRANGE MOUND
IS NOT AN ANCIENT EMERALD MINE.

Rose:
THIS IS SEDIMENTARY LIMESTONE,

AND PRECIOUS STONES DON'T FORM
IN SEDIMENTARY LIMESTONE.

THEY NEED PRESSURE
AND THEY NEED TIME,

NEITHER OF WHICH YOU HAVE HERE.

Narrator: TO ARCHEOLOGIST
KAREN BELLINGER,

THE WAY THE HOLES ARE LAID OUT
LOOKS REMARKABLY FAMILIAR.

IT REALLY BRINGS TO MIND
ANOTHER SITE IN EGYPT

WHERE THERE'S A NUMBER OF CAVES,

WHICH ARE ACCESSED FROM HOLES
IN THE GROUND,

MUCH LIKE THESE.

Narrator: NEAR THE ANCIENT CITY
OF ASWâN,

500 MILES SOUTH OF SIWA,

ON THE BANKS OF THE NILE

SITS THIS SIMILARLY
POCKMARKED FEATURE.

THIS PLACE IS CALLED
THE TOMBS OF THE NOBLES.

IT'S A BURIAL GROUND,
WHAT WE CALL AN ACROPOLIS.

THESE HOLES IN THE GROUND LEAD
TO THESE ROUGH-HEWN CAVERNS,

IN WHICH WE FIND
BURIED EGYPTIAN ELITE,

MILITARY COMMANDERS,
AND SECULAR LEADERS.

Narrator:
WHEN ARCHEOLOGISTS GAIN
ACCESS TO THE VAST MOUND,

THEY CONFIRM THE HOLES
SPOTTED IN THE SATELLITE IMAGE

ARE ENTRANCES TO TOMBS.

THEY'VE BEEN CARVED
RIGHT OUT THE LIMESTONE

AND HAVE BEEN THERE
FOR THOUSANDS OF YEARS.

THIS WHOLE THING SEEMS
TO BE A HIERARCHY --

YOU HAVE PEOPLE ON THE OUTSIDE

WHO COULD ONLY AFFORD
A SMALL PLACE,

AND THEN AS YOU GO UP THE MOUND

YOU HAVE MUCH
MORE ELABORATE TOMBS.

IT'S FEASIBLE THAT PERHAPS
WE MIGHT FIND

A VERY IMPORTANT
INDIVIDUAL BURIED HERE.

Narrator: INSIDE THIS MOUNTAIN
OF THE DEAD,

INVESTIGATORS DISCOVER
SOMETHING INTRIGUING.

Altaweel: THESE TOMBS ARE FROM
A VARIETY OF CULTURES,

SO IT SUGGESTS DIFFERENT
FOREIGNERS WERE COMING IN

TO THIS REGION FROM THE OUTSIDE,
BURYING THEIR DEAD THERE.

Narrator: ARCHEOLOGISTS
BELIVE SOMETHING SPECIAL

IS BRINGING KINGS AND NOBLES

FROM FAR AND WIDE
TO THE MOUNTAIN OF THE DEAD.

**

ACCORDING TO INSCRIPTIONS
ON A NEARBY TEMPLE,

THERE WAS ONCE AN ORACLE HERE,

ONE WITH EXTRAORDINARY POWERS
OF DIVINATION AND PROPHECY.

Altaweel:
THE STORY OF ALEXANDER THE GREAT
COMING TO GET ADVICE

FROM THE ORACLE AND ESSENTIALLY
RECEIVING THE KEYS TO EGYPT,

THAT IS BECOMING
THE ANOINTED PHARAOH

WHO WOULD HAVE LEGITIMACY
IN RULING EGYPT.

Narrator: ON HIS DEATHBED,

ALEXANDER ASKS
FOR HIS BODY TO BE BURIED

AT THE ORACLE'S TEMPLE IN SIWA.

YET TO THIS DAY,
NO ONE KNOWS FOR CERTAIN

WHERE THE
GREAT KING'S BODY RESTS,

AND MUCH OF THE MOUNTAIN
OF THE DEAD REMAINS UNEXPLORED.

Chamberlain: FINDING WHERE
ALEXANDER THE GREAT IS BURIED

WOULD BE PROBABLY

THE GREATEST ARCHEOLOGICAL
DISCOVERY OF ALL TIME.

**

Narrator: COMING UP...

A MYSTERY NOXIOUS MIST
SPREADS TERROR IN ENGLAND.

I DON'T WHAT IT IS,
BUT I KNOW IT'S NOT GOOD.

**

Narrator: AUGUST 29, 2017.

A SATELLITE FLYING 400 MILES

ABOVE THE ENGLISH CHANNEL
CAPTURES

SOMETHING UNUSUAL
IN THE WATERS BELOW.

IT IS A PLUME OF GREEN SMOKE
COMING OUT OF THE SEA.

Narrator: IMAGE ANALYSIS
SUGGESTS

THAT THE GREEN PLUME
IS TWO MILES LONG,

AND IT'S MOVING TOWARDS
THE ENGLISH COAST.

IT'S ALMOST LIKE THERE'S
THIS NEW VOLCANO

COMING UP OUT OF
THE ENGLISH CHANNEL,

JUST SPEWING, LIKE,
A SULFURIC GAS.

I DON'T KNOW WHAT IT IS,
BUT I KNOW IT'S NOT GOOD.

**

Narrator: THREE HOURS
AFTER THE IMAGE IS TAKEN,

THE DISPERSED GREEN MIST
ROLLS ON TO BEACHES CROWDED

WITH UNSUSPECTING VACATIONERS.

AT FIRST, THEY WERE JUST
THINKING, "OH, LOOK,

WE'RE GETTING FOG
OFF THE WATER,"

AND THEY PROBABLY DIDN'T
PAY MUCH ATTENTION TO IT.

THEN ALL OF A SUDDEN,
PEOPLE START REACTING TO IT.

PEOPLE GETTING SICK
AND NAUSEOUS, DIZZY.

Narrator: WITHIN MINUTES,
THE ONCE-BUSY BEACHES

LIE DESERTED.

**

Capps: IT'S LIKE
A STEPHEN KING NOVEL.

THIS EERIE MIST BEGINS
TO DESCEND OUT OF NOWHERE,

TURNING YOUR BEACH DAY
INTO THIS HORROR MOVIE.

[ SIREN WAILS ]

Narrator: WHEN 150 PEOPLE
REQUIRE MEDICAL TREATMENT,

AUTHORITIES REALIZE
THEY HAVE A PROBLEM.

THEY SEND IN HAZMAT TEAMS.

THE BRITISH GOVERNMENT
LAUNCHES AN INVESTIGATION.

PEOPLE NEED ANSWERS, RIGHT?

YOU DON'T JUST BECOME
SICK FOR NOTHING.

Narrator: THE MYSTERY
OF THE TOXIC SEA MIST

COMES TO THE ATTENTION
OF MARINE BIOLOGIST ROB NELSON.

WHEN I SEE THIS SATELLITE IMAGE,
THE FIRST THING THAT I THINK OF

IS SOME ORGANISM
IN THE SEA -- ALGAE.

Narrator: ALGAE ARE SIMPLE,
PRIMITIVE ORGANISMS,

WHICH USE SUNLIGHT
TO CREATE ENERGY.

IN SUMMER MONTHS, SUCH AS WHEN
THE SATELLITE IMAGE WAS TAKEN,

AND WITH THE RIGHT CONDITIONS,

COLONIES SEVERAL MILES
LONG APPEAR

ON THE SURFACE OF THE SEA.

ALGAL BLOOMS, IN GENERAL,

POP UP WHEN YOU HAVE
AN INFLUX OF NUTRIENTS.

THE ALGAE STARTS TO REPRODUCE,
AND YOU GET THESE ALGAL BLOOMS.

**

Narrator: ALTHOUGH ONLY
A SMALL PERCENTAGE

OF ALGAL BLOOMS ARE TOXIC,

BIOLOGISTS CONFIRM THAT SOME
CAN PRODUCE NOXIOUS GASES

LIKE AMMONIA.

Chamberlain: THEY'RE ESSENTIALLY
PUMPING OUT POISONOUS GASES,

AND WE KNOW THAT IT CAN
ALSO AFFECT HUMANS.

IF YOU WERE CLOSE ENOUGH
TO BREATHE THIS STUFF IN,

IT COULD REALLY MESS YOU UP.

Narrator: BUT THE ALGAL
EXPLANATION DOESN'T ADD UP.

THE STRONG CURRENTS OF
THE ENGLISH CHANNEL

SHOULD MAKE IT NEARLY
IMPOSSIBLE FOR IT TO GROW HERE.

AND ONCE SCIENTISTS
FROM THE NEARBY

PLYMOUTH MARINE LAB
HEAD TO THE PATCH OF SEA

IN THE SATELLITE IMAGE,

THEY FIND NO TRACE
OF ALGAE IN THE WATER.

THEY DIDN'T FIND
ANY TOXIC ALGAE,

WHICH BEGS THE QUESTION,

"WHAT CAUSED THIS TOXIC MIST
IF IT WASN'T ALGAE?"

**

Narrator: INVESTIGATORS SHIFT
THEIR FOCUS

TO THE ENGLISH CHANNEL ITSELF,

THE WORLD'S BUSIEST
STRETCH OF WATER.

WHEN YOU LOOK AT
THE SATELLITE IMAGE,

YOU CAN SEE THAT IT'S CLEARLY
COMING FROM OUT OF THE WATER.

THE NEXT QUESTION IS,

"WHAT'S DOWN THERE
IN THE ENGLISH CHANNEL?"

Narrator: HISTORICAL MARITIME
RECORDS REVEAL

THAT THROUGHOUT HISTORY,
THE ENGLISH CHANNEL

IS ONE OF THE MOST PERILOUS
SHIPPING STRAITS ON THE PLANET.

THE ENTIRE ENGLISH CHANNEL
IS FULL OF SUNKEN SHIPS.

IT'S LIKE A SHIP GRAVEYARD.

Narrator: MARINE ARCHEOLOGISTS
HAVE CATALOGUED

THOUSANDS OF SHIPWRECKS HERE,

SOME DATING BACK AS FAR
AS THE BRONZE AGE.

**

INVESTIGATORS FOCUS ON
THE HUNDREDS SUNK

DURING THE 20th CENTURY'S
TWO WORLD WARS.

MANY OF THEM TOOK UNKNOWN
QUANTITIES OF MUNITIONS

AND LETHAL CHEMICALS
WITH THEM TO THE SEABED.

WHEN THE BRITISH MARITIME
AND COASTGUARD AGENCY

COMPARES THE LOCATIONS OF KNOWN
WRECKS WITH THE GREEN MIST,

ONE STANDS OUT -- THE SS MIRA.

THE MIRA IS A WORLD WAR I
TANKER SHIP

THAT WAS FULL OF GASOLINE.

THE GERMANS ATTACKED
WITH A SUBMARINE,

AND IT SANK TO THE BOTTOM,

RIGHT UNDER WHERE
WE SEE THIS PLUME.

Narrator: OIL CAN GIVE OFF
NOXIOUS FUMES WHEN IT BURNS,

BUT SCIENTISTS DOUBT
THAT LEAKING OIL

FROM THE 100-YEAR-OLD WRECK

COULD ACCOUNT FOR THE GREEN MIST

AND THE TROUBLING
MEDICAL SYMPTOMS.

THE SOURCE OF THE
STRANGE TOXIC MIST

CAPTURED IN THE SATELLITE IMAGE
REMAINS A MYSTERY.
