Josh: ON THIS EPISODE
OF "EXPEDITION X,"

MY TEAM TREKS DEEP INSIDE
THE LONGEST CAVE SYSTEM

IN THE WORLD.

Jessica:
IT IS OVER 400 MILES LONG.

SO THIS IS THE EDGE
OF THE MAP RIGHT HERE.

THAT IS A STEEP DROP.

...TO INVESTIGATE 5,000 YEARS
OF STRANGE PHENOMENA...

THERE'S PLACES THAT WE REALLY
SHOULDN'T GO.

Josh:
...A SHADOWY FIGURE...

THIS IS EXACTLY
WHERE IT WAS.

...AND A PARANORMAL FORCE
THAT'S CLAIMING VICTIMS.

THEY COMPLETELY DISAPPEARED.

JUST SAW SOMETHING PASS
RIGHT IN FRONT OF MY FACE.

I WANT TO GET OUT OF HERE.

OUT OF THE SHADOWS
COMES THIS PRESENCE.

- Jessica: WHAT IS THAT?
- IT'S, LIKE, GOING CAVE CRAZY.

THIS ISN'T GOOD.

WE'VE GOT TO GET
OUT HERE RIGHT NOW.

WATER'S COMING IN.
LET'S GO.

HOLY [BLEEP]!
OH!

MY NAME IS JOSH GATES.

IN MY TRAVELS, I'VE EXPERIENCED
STRANGE THINGS THAT DEFY LOGIC

AND MADE ME QUESTION EVERYTHING.

OH, MY GOD.

NOW, I'VE PUT TOGETHER A TEAM

TO INVESTIGATE THE STRANGER SIDE
OF THE UNKNOWN.

LET'S GO.

Josh:
PHIL TORRES IS A SCIENTIST

WHO HUNTS FOR
RATIONAL EXPLANATIONS.

Josh: JESSICA CHOBOT'S
PARANORMAL RESEARCH

HAS MADE HER A TRUE BELIEVER.

THERE IS A MONSTER
LIVING IN THIS FOREST.

PHIL, PHIL, PHIL,
I JUST SAW SOMETHING RUN ACROSS.

Josh: TOGETHER, WE'RE SEARCHING
FOR ANSWERS...

WHAT IS THAT?

...TO THE WORLD'S
MOST EXTRAORDINARY MYSTERIES.

THIS IS "EXPEDITION X."

- -Captions by VITAC --

CAPTIONS PAID FOR BY
DISCOVERY COMMUNICATIONS

ONE OF THE THINGS THAT PEOPLE
ASK ME ALL THE TIME

IS, HAVEN'T
WE EXPLORED EVERYTHING?

YOU KNOW,
HAVEN'T WE MAPPED EVERYTHING?

HAVEN'T WE BEEN
EVERYWHERE AT THIS POINT?

AND OF COURSE, THE ANSWER IS NO.

TAKE THE AMAZON RAINFOREST,
FOR EXAMPLE.

OVER A BILLION ACRES,
AND HUGE AREAS OF IT

HAVE NOT BEEN EXPLORED
IN MODERN TIMES.

FOR EXAMPLE, THIS AREA CALLED
VALE DO JOVARI IN BRAZIL.

THERE ARE OVER A DOZEN
UNCONTACTED TRIBES

LIVING THERE TODAY.

YEAH, AND I THINK A LOT
OF PEOPLE HAVE THE TENDENCY

TO JUST THINK OF LAND.

I MEAN,
I ALWAYS THINK OF THE OCEAN.

I MEAN, IT'S HUGE.

WE'VE JUST STARTED EXPLORING
THE DEPTHS OF IT.

WE'RE FINDING NEW SPECIES
LIVING THERE ALL THE TIME.

SO, YOU KNOW, WHO'S TO SAY
WHAT ELSE WE MIGHT FIND?

AND IN FACT, THE TOPIC
OF UNEXPLORED PLACES

IS REALLY AT THE HEART
OF TODAY'S CASE.

SO A FEW WEEKS AGO,
I RECEIVED A MESSAGE

FROM A GUY NAMED MARK WENNER.

NOW, MARK IS
A CAVING EXPERT.

HE HAS EXPLORED CAVES
ALL OVER THE WORLD.

HE LECTURES AROUND THE WORLD
ON CAVES AND CAVE SAFETY.

AND IN PARTICULAR,
HE HAS SPENT THOUSANDS OF HOURS

IN A PLACE CALLED MAMMOTH CAVE.

SO YOU MAY KNOW MAMMOTH CAVE.
THIS IS IN KENTUCKY.

IT IS ACTUALLY THE LONGEST
CAVE SYSTEM IN THE WORLD.

NOW, MARK KNOWS HIS STUFF.
THIS GUY IS A REAL-DEAL EXPERT,

WHICH IS WHY I WAS
SO SURPRISED TO HEAR

ABOUT HIS TEAM'S RECENT
EXPERIENCE DOWN IN A CAVE.

CHECK THIS OUT.

WE'VE BEEN MAPPING
MAMMOTH CAVE FOR 14 YEARS.

INITIALLY,
THE FIRST COUPLE TRIPS

WERE A PRETTY STANDARD
OPERATION.

THE SECOND OR THIRD TRIP,
THOUGH,

WE EXPERIENCED SOME THINGS
THAT WERE VERY UNEXPLAINABLE.

Josh: MEASURING 420 MILES
AND COUNTING,

THE MAMMOTH CAVE
IN CENTRAL KENTUCKY

WAS INHABITED
BY NATIVE AMERICANS

STARTING ABOUT 4,000 YEARS AGO.

THEY USED THE CAVES AS SHELTER
AND FOR BURIAL RITUALS,

A SPIRITUAL REALM WHERE THEY
COULD COMMUNE WITH THE DEAD.

THEN, ABOUT
2,000 YEARS AGO,

THEY SUDDENLY
ABANDONED THE CAVES.

SOME DESCENDANTS SAY
THEIR ANCESTORS WERE DRIVEN AWAY

BY ANCIENT SPIRITS
DEEP WITHIN THE DARKNESS.

A MORE CONVENTIONAL EXPLANATION
IS THAT CHANGES IN CLIMATE

DROVE GAME ANIMALS AWAY, AND
THE PEOPLE FOLLOWED THE FOOD.

WHATEVER THE REASONS
FOR THEIR ABRUPT DEPARTURE,

MAMMOTH CAVE REMAINS
A PLACE OF MYSTERY.

IN THE PAST FEW CENTURIES,

THERE HAVE BEEN NUMEROUS
DEATHS AND DISAPPEARANCES

AND MANY CLAIMS
OF PARANORMAL ACTIVITY.

IN THE DEEPEST
UNCHARTED PARTS OF THE CAVE,

PEOPLE HAVE REPORTED
FEELING LIKE THEY WERE STALKED

AND EVEN TOUCHED
BY A MENACING, SHADOWY FIGURE.

WHILE MANY CHALK UP SUCH REPORTS
TO COLORFUL LEGEND AND LORE,

OTHERS, INCLUDING CAVE EXPERTS
LIKE MARK, DISAGREE,

HAVING EXPERIENCED THIS
TERRIFYING PRESENCE FIRSTHAND.

Wenner: SO, THE FOUR OF US WERE
WALKING DOWN THE PASSAGE,

AND OUT OF THE SHADOWS
COMES THIS PRESENCE.

[ WHOOSH, RUMBLE ]

THAT'S THE ONLY WAY
THAT I CAN EXPLAIN IT.

IT WAS AS REAL AS THE GUYS
STANDING NEXT TO ME.

IN FACT, SO MUCH SO THAT
I HAD TO TURN TO SEE

IF ONE OF THOSE GUYS
HAD WALKED BEHIND ME.

SO I SAID,
"YOU GUYS FEEL THAT PERSON

THAT JUST ENTERED OUR PARTY?"

AND MATT, WHO WAS ON THE END,
SAID "ABSOLUTELY."

REALLY STRANGE STUFF.

NOW, I'VE SPENT A LOT OF TIME
IN CAVES OVER THE YEARS,

AND LOOK, THEY ARE EXTREMELY
STRANGE, MYSTERIOUS WORLDS.

I MEAN, THIS IS QUITE
LITERALLY THE UNDERWORLD.

WOW. IT IS SPECTACULAR IN HERE.

BUT THIS IS SOMETHING
I'VE NEVER EXPERIENCED.

NO, THIS IS NEXT LEVEL.

I MEAN, I DEFINITELY HAVE HEARD
OF MAMMOTH CAVE BEFORE.

A LOT OF PEOPLE HAVE REPORTED
SHADOW FIGURES, STRANGE SOUNDS,

AND OBVIOUSLY EVEN MARK
AND HIS TEAM

EXPERIENCED SOME SORT
OF PRESENCE DOWN THERE.

SO ALL OF THAT STUFF COMBINED,

I DON'T THINK
YOU CAN DISMISS IT.

TO ME, THAT'S VERY MUCH
WORTH INVESTIGATING.

PHIL, WHAT DO YOU THINK?

CAVES ARE THE EXACT
TYPE OF PLACE

YOU WOULD EXPECT A STORY LIKE
THIS TO KIND OF COME ALIVE.

RIGHT.
THEY ARE INCREDIBLY DARK.

THEY ARE DISORIENTING.
AND THROUGHOUT HISTORY,

PEOPLE ALL OVER THE WORLD
HAVE ALWAYS LOOKED AT THEM

AS MYSTICAL OR A PORTAL
TO THE OTHER SIDE.

SO TO ME, IT'S NO SURPRISE THAT
PEOPLE WOULD THINK A DEEP,

DARK CAVE IS HAUNTED
OR HAS SOMETHING LIVING IN IT.

BUT IT DOES GIVE ME PAUSE
WHEN A CAVING EXPERT LIKE MARK

HAS A STORY LIKE THAT.

RIGHT.
THIS IS A REALLY CREDIBLE GUY

AND PART OF
A TEAM OF SCIENTISTS.

RIGHT? THIS ISN'T JUST
ONE PERSON HAVING AN EXPERIENCE.

SO THE MISSION IS SIMPLE.
WHAT'S GOING ON IN MAMMOTH CAVE

THAT HAS THESE SCIENTISTS
SO SPOOKED?

OR IS NOTHING GOING ON?

IS IT NOTHING MORE THAN
CAMPFIRE STORIES AND FOLKLORE?

SO TO FIND OUT,
I'M GOING TO HAVE YOU JOIN MARK

ON HIS NEXT MISSION

TO AN UNCHARTED SECTION
OF THE CAVE.

- YOU UP FOR IT?
- ABSOLUTELY.

LET'S GO CAVING.

Josh: JESSICA AND PHIL
MAKE THE 800-MILE DRIVE

FROM THE BIG CITY
TO CAVE CITY, KENTUCKY.

HERE, BENEATH THE TREE-LINED
STREETS AND COUNTRY STORES,

THIS SMALL CITY HIDES
A SECRET --

THE LONGEST CAVE SYSTEM
IN THE WORLD.

WHAT DO YOU THINK HE WOULD DO
IF YOU ACTUALLY

HAD SOMETHING YOU COULDN'T
EXPLAIN HAPPEN TO YOU?

I WOULD HAVE SOMEBODY CHECK
THE OXYGEN READING.

I WOULD ASSUME THAT WE'RE IN
AN AREA OF THE CAVE

WHERE, LIKE,
THERE'S SOME OTHER GAS

AND SO YOU'RE
STARTING TO TRIP.

WHAT I'M REALLY EXCITED ABOUT,
IT'S WHAT JOSH IS SAYING,

WHERE THEY'RE STILL
EXPLORING LEFT TO BE DONE,

AND I DON'T LIKE EXPLORING

JUST FOR THE SAKE
OF SAYING I'VE BEEN THERE.

THIS IS EXPLORING FOR SCIENCE
AND TO DOCUMENT SOMETHING

AND TO MAP SOMETHING
NO ONE'S EVER DONE BEFORE.

SO I LOVE THAT
BIGGER CONTRIBUTION

TO WHAT WE'RE ADDING
TO SOLVING THE MYSTERY HERE.

AND I THINK IT'S REALLY,
REALLY COOL

THAT WE'RE GOING INTO
A SECTION OF THE CAVES

THAT HAVE NEVER BEEN GONE INTO.
OH, YEAH.

Josh: TO DATE,
THE MAMMOTH CAVE SYSTEM

HAS 25 KNOWN ENTRANCES

THAT ARE SPREAD OUT OVER
82 SQUARE MILES OF KENTUCKY.

PHIL AND JESS
ARE HEADED TO THIS ONE,

9 MILES TO THE WEST
OF CAVE CITY.

THEY'RE HERE TO MEET
WITH MARK WENNERS' COLLEAGUE,

DR. PAT KAMBESIS.

HI.
IT'S GOOD TO MEET YOU.

GOOD TO MEET YOU.

Josh: PAT TEACHES GEOGRAPHIC
INFORMATION SYSTEM MAPPING,

OR G.I.S., AT WESTERN
KENTUCKY UNIVERSITY.

SHE ALSO RUNS KENTUCKY'S
CAVE RESEARCH FOUNDATION

AND HAS PERSONALLY EXPLORED AND
MAPPED CAVES ALL OVER THE WORLD.

WELCOME TO MAMMOTH CAVE,
LONGEST CAVE IN THE WORLD.

IT IS OVER 400 MILES LONG,

BUT YOU UNDERSTAND THAT'S
NOT LIKE 400 MILES

IN A STRAIGHT LINE, RIGHT?
YEAH.

IT'S LIKE 400 MILES
STACKED ON LIKE FIVE LEVELS.

Josh: GEOLOGISTS ESTIMATE THAT
THE ORIGINS OF THE CAVE SYSTEM

DATE BACK
15 MILLION YEARS TO WHEN

THE GREEN RIVER CARVED ITS WAY
THROUGH A THICK CAP

OF SANDSTONE BELOW,

EXPOSING A 600-FOOT LAYER
OF SOFT LIMESTONE.

OVER THE COURSE
OF THE NEXT 10 MILLION YEARS,

FLOWING WATER HOLLOWED OUT
THE STONE,

CREATING A LABYRINTH OF
STACKED SUBTERRANEAN PASSAGES

THAT ARE STILL BEING MAPPED
TO THIS DAY.

LET'S GO SEE SOME CAVE.

ALL RIGHT, THANKS.
LET'S DO IT.

♪♪

WHOA.

WOW.

[ WATER DRIPPING ]

♪♪

SO WHAT WAS THE CAVE LIKE BEFORE
ALL THE MODERN CONSTRUCTION?

Kambesis:
WELL, IT WAS A LOT MORE RUGGED THAN WHAT YOU SEE NOW.

THE ORIGINAL NATIVE AMERICANS
WERE THE EXPLORERS.

YOU HAD TO BE REALLY BALLSY
TO COME HERE

WITH CANE TORCHES AND BAREFOOT.

THERE'S NO LIGHT.

SO YOU HAVE TO FIGURE
THAT THEY HAD TO OVERCOME A LOT

JUST TO COME IN HERE.

Josh: THE CAVES WERE OCCUPIED BY
ANCESTORS OF THE CHEROKEE TRIBE.

THEY MINED THE UPPER
THREE LEVELS OF THE CAVE SYSTEM,

SEEKING MINERALS SUCH AS GYPSUM
AND SELENITE,

WHICH WERE USED FOR TRADE,
RITUALS, AND EVEN MEDICINE.

AND THEN AFTER ABOUT
2,000 YEARS AGO,

THERE ISN'T A LOT OF EVIDENCE
OF THEIR ACTIVITY.

SO IT'S LIKE THEY COMPLETELY
DISAPPEARED FROM HERE.

WE DON'T KNOW.
SO THERE'S A LOT OF MYSTERY.

I MEAN, THERE'S A LOT OF THINGS
THAT WE KNOW,

BUT THERE'S A LOT OF THINGS
THAT WE DON'T KNOW.

DID THEY EVER USE THE CAMP
FOR BURIALS AT ALL?

THERE HAVE BEEN SOME MUMMIES
FOUND IN HERE,

BUT THEY DIDN'T MUMMIFY THEM.
REALLY?

IT'S BECAUSE OF THE...
THE ATMOSPHERE?

THE ATMOSPHERE OF THE CAVE.

Josh: THE CONSISTENT TEMPERATURE
AND HUMIDITY

AS WELL AS THE SALT
FOUND IN THE SOIL

MEANS THAT MAMMOTH CAVE
IS THE PERFECT ENVIRONMENT

FOR MUMMIFYING A BODY.

ALTHOUGH THE EXACT NUMBER
OF PEOPLE WHO HAVE DIED

IN MAMMOTH CAVE IS UNKNOWN,

CAVING EXPERTS ARE CERTAIN
THE NUMBER OF DEATHS

IS VASTLY UNDERREPORTED.

THE BODIES OF MOST PEOPLE
WHO DISAPPEAR IN

AND AROUND THE CAVES
ARE NEVER FOUND.

Jessica:
WHAT ARE YOUR THOUGHTS ON PARANORMAL ACTIVITY IN THE CAVE?

Kambesis: WELL, FIRST, YOU KNOW,
I'M A SCIENTIST.

MM-HMM.
HOWEVER,

I LIKE TO KEEP
AN OPEN MIND.

AND SO I WOULDN'T
TOTALLY DISCOUNT IT.

HMM.
I MEAN, YOU KNOW...

YOU'RE MY FAVORITE KIND
OF SCIENTIST.

[ LAUGHTER ]
I'M RIGHT HERE.

DO YOU NEED A JOB?

I'M JUST KIDDING.

WE'VE HEARD REPORTS OF PEOPLE
SEEING THINGS IN HERE,

HEARING THINGS IN HERE,
CHANTING, OR EVEN BEING PUSHED.

YEAH.
ESPECIALLY WHEN THEY GO INTO

UNMAPPED SECTIONS OF THE CAVE.

SO WHAT ARE YOUR THOUGHTS
ON THAT?

YOU KNOW, A LOT OF IT,
IT COULD BE PSYCHOLOGICAL.

IF YOU STAY IN THE CAVE
LONG ENOUGH,

YOU START TO HEAR THINGS
AND YOU START TO SEE THINGS.

IT'S LIKE GOING CAVE CRAZY.

YEAH, BECAUSE
YOU'RE SENSORY DEPRIVED.

YOUR MIND STARTS
TO PLAY TRICKS ON YOU.

AND SO MAYBE YOU COULD GO
A LITTLE CAVE CRAZY.

OH. THAT'S PRETTY TERRIFYING,
ACTUALLY.

Josh: SENSORY DEPRIVATION
CAN CAUSE ANXIETY

AND EVEN HALLUCINATIONS
IN AS LITTLE AS 15 MINUTES.

THE BRAIN SEEKS OUT
SENSORY PATTERNS

AND WHEN NONE EXIST,
IT CREATES ITS OWN.

Phil: WHOA.

HAVE YOU HAD ANY EXPERIENCES
WHILE DOWN HERE

THAT YOU CAN'T REALLY EXPLAIN?

I ACTUALLY HAVE.

I WAS ON A TRIP
WHERE WE WERE DOWN THERE,

AND WE WERE JUST KIND OF SITTING
AROUND ON THIS FLAT ROCK.

AND IT JUST KIND OF
GOT REALLY WEIRD,

LIKE THERE WAS
SOME SORT OF, LIKE,

"IS THERE SOMEBODY HERE?"
YOU KNOW?

EVERYBODY GOT THAT FEELING.
YEAH.

WE GOT A LITTLE BIT SPOOKED.

AND THEN WE STARTED HEARING,
LIKE, ROCK FALL,

AND WE WERE LIKE,
"OOH."

YOU KNOW,
BECAUSE ALL OF US ARE HERE.

YEAH.
THE FEELING WAS TOO STRONG,

AND WE'RE LIKE, "OKAY,
WE'RE OUT OF HERE."

WOW.
SO BAD ENOUGH TO SCARE YOU OUT?

OKAY.
OH, YEAH, WE LEFT.

Phil: IN AN ENCOUNTER
SIMILAR TO MARK'S,

PAT SAID SHE, TOO,
SENSED A DARK SHADOW

AND FELT THE PRESENCE
OF SOME TYPE OF ENTITY.

WHATEVER IS DOWN HERE
SEEMS TO HAVE SCARED

THIS EXTREMELY EXPERIENCED
CAVER ENOUGH

THAT SHE AND HER TEAM
WANTED TO GET OUT IMMEDIATELY.

Jessica:
TOMORROW WE'LL JOIN MARK AND PAT ON A TWO-DAY EXPEDITION

TO EXPLORE UNMAPPED SECTIONS
OF THE CAVE.

IN THE MEANTIME,
THEY'VE ARRANGED FOR US TO MEET

WITH A NATIVE AMERICAN EXPERT
NAMED BRAVEHEART

TO HELP US UNDERSTAND
THE LOCALS' VIEW

OF WHAT'S REALLY HAPPENING
IN MAMMOTH CAVE.

HYAH!
[ HORSE WHINNIES ]

Jessica: SHE LIVES IN THE HILLS
DIRECTLY ABOVE THE CAVERNS

WHERE HER ANCESTORS ONCE LIVED.

SUPPOSEDLY, IF WE KEEP HEADING
WEST FROM THE STABLES,

WE'LL FIND HER CABIN
JUST PAST A FRESH SPRING.

Jessica: ALL RIGHT,
SO THERE'S THERE'S SPRING.

WE JUST GOT TO GO WEST,

TO FIND.

YOU WOULDN'T HAVE FOUND ME
IF A SPIRIT HADN'T SENT YOU.

HOW LONG HAVE YOU
LIVED OUT HERE?

I'VE LIVED HERE 20 PLUS YEARS.

SO FROM YOUR PERSPECTIVE,
WHAT'S GOING ON IN THESE CAVES?

A LOT OF THESE CAVES
WERE USED AS BURIALS.

THERE'S SHAMANS.

THERE'S MEDICINE PEOPLE
THAT HAS BEEN BURIED HERE

LONG BEFORE EUROPEANS
EVER CAME TO THIS COUNTRY.

I BELIEVE THAT
IN THESE CAVES,

THERE IS ACTUALLY A PORTAL
TO THE AFTERLIFE.

Josh: MY TEAM IS IN KENTUCKY,

CONNECTS TO THE UNDERWORLD

IN A VERY LITERAL WAY.

I BELIEVE THAT
IN THESE CAVES,

THERE IS ACTUALLY A PORTAL
TO THE AFTERLIFE.

Josh: THE CAVES
BENEATH THIS REGION

HAVE HISTORICALLY BEEN
A SACRED SPACE

FOR TRIBES LIKE THE CHEROKEE,

A PLACE OF REFUGE
FROM THE ELEMENTS,

BUT ALSO A PLACE WHERE GROUPS
CONDUCTED MYSTICAL,

FUNERARY RITUALS,
RITUALS THAT

SOME BELIEVE UNLEASHED POWERFUL,
UNSEEN FORCES.

THERE WAS A CONFLICT
BETWEEN BOTH SIDES OF THE GRASS,

AS WE CALL IT,
THE DEAD AND THE LIVING.

AND IT BECAME ALMOST
A SPIRITUAL WARFARE.

THE DEAD --
THEY WANT TO BE ALIVE.

AND SOME OF THEM HASN'T
OFFICIALLY CROSSED OVER,

SO THEY'RE JEALOUS
AND THEY'RE ANGRY.

Jessica: SHE TELLS US THAT THE
DEEPER INTO THE CAVE WE GO,

FOR THE GESTURE.

TOWARDS THE OUTSKIRTS OF TOWN

TO JOIN THE TEAM ABOUT

I'M LEGIT FEELING WAY
BETTER GOING TO THE CAVES

AFTER GETTING THESE BAGS

I THINK IT WAS A REALLY

NICE GESTURE,

THAT WAS

BUT INSTEAD, YOU'RE LIKE
TOTALLY DOWN.

WHEN I HEAR
THESE STORIES OF PORTAL

I WONDER, LIKE,
WHAT'S THE SEED OF TRUTH TO IT?

WHAT WAS REALLY
HAPPENING BACK THEN?

THERE COULD HAVE BEEN
ROCK SLIDES.

THERE COULD HAVE BEEN FLOODS.
MM-HMM.

THERE COULD HAVE BEEN DISEASE
FROM THE DEAD

THAT THEY WERE STORING
IN THE CAVES.

I DO THINK THERE'S
A SEED OF TRUTH THERE,

BUT WHAT'S THE PARANORMAL
OR MYTHOLOGICAL SEED?

WHY DOES IT HAVE TO BE
SOMETHING...

REAL?

BUT I WOULD COUNTER THAT
IN REGARDS TO THE CAVING TEAM,

WE'RE GONNA BE
MEETING UP WITH,

THEY THEMSELVES HAVE MENTIONED
WEIRD EXPERIENCES

THAT THEY CAN'T EXPLAIN
THAT THEY'VE HAD IN THE CAVE.

THEY'RE SCIENTISTS, AND YET
THEY'RE STILL MENTIONING THIS.

SO EXPLAIN THAT ONE.

THESE THINGS ARE HAPPENING

AND YOU STILL TURN
A BLIND EYE TO THEM.

IT'S NOT A BLIND EYE.

PHIL AND JESSICA'S
INVESTIGATION INTO MAMMOTH CAVE

IS A STARK REMINDER OF SOMETHING
I'VE EXPERIENCED FIRSTHAND.

REGARDLESS OF WHETHER
YOU BELIEVE A CAVE

MIGHT BE HOME
TO SUPERNATURAL FORCES,

IT COULD CERTAINLY BE A PLACE
THAT TURNS DEADLY IN A HURRY.

ON A RECENT EXPEDITION
TO ECUADOR,

MY OWN TEAM DESCENDED
HUNDREDS OF FEET INTO THE EARTH

TO EXPLORE THE MASSIVE
TAYOS CAVES.

IN PLACES LIKE THIS,
EVERY STEP COUNTS.

THE CARELESS PLACEMENT OF A FOOT
OR A LOSS OF BALANCE IN THE DARK

CAN MEAN THE DIFFERENCE BETWEEN
GETTING OUT OF A TIGHT SPOT

AND NOT MAKING IT OUT ALIVE.

AND WHILE PEOPLE THINK OF CAVES
AS EMPTY PLACES,

THEY'RE ACTUALLY
TEEMING WITH LIFE.

THEY ARE ALSO TREACHEROUS
CONDUITS FOR WATER,

AND WEATHER CONDITIONS
ABOVE CAN LEAD

TO UNEXPECTED
FLOODING UNDERGROUND.

THESE REALITIES
WERE DRAMATICALLY HIGHLIGHTED

IN 2018,
WHEN 12 BOYS AND THEIR COACH

WERE TRAPPED UNDERGROUND
IN A FLOODED CAVE IN THAILAND,

SPARKING A DRAMATIC
RESCUE EFFORT

WITH THOUSANDS OF VOLUNTEERS
AND 100 TRAINED DIVERS.

SO IF YOU ARE VENTURING
INTO A CAVE,

GO WITH AN EXPERIENCED GUIDE,
GO WITH THE PROPER GEAR,

AND ALWAYS GO WITH A PLAN
FOR HOW TO GET BACK OUT SAFELY.

ARE THESE JUST THE TRICKS

OR IS THERE
SOMETHING EXTRAORDINARY,

SOMETHING PARANORMAL GOING ON?
