[Josh] The Chesapeake and Ohio Canal was a monumental

and deadly feat of American engineering.

All those men down here...

I mean, those bodies floated all the way down the Potomac.

[Josh] But today, this historic waterway

and its crumbling ruins

are said to be a hotbed of paranormal activity.

That was a scream.

[Josh] Locals are reporting violent encounters

with mysterious spirits.

There's this figure,

all of a sudden, he turns around and looks at me...

-Oh, my God! -[Jessica Chobot] What the [bleep]?

[Josh] It's my team's most terrifying investigation yet...

Did you die here?

Whoa, whoa, whoa, whoa, whoa!

What the hell was that?

Phil, the alarm went off.

...as Jess and Phil confront a dark chapter

in our nation's history.

Definitely where the bodies are kept.

Oh, my God, something touched me.

[narrator reading]

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.

Phil Torres is a scientist who hunts for rational explanations.

Jessica Chobot's paranormal research has made her a true believer.

Phil, did you see that?

I just saw something run across.

Together, we're searching for answers...

What is that?

...to the world's most extraordinary mysteries.

This isExpedition X.

So, what if I told you that many people believe

that the most haunted spot in America

is not an old house, it's not a hotel,

it's not even some Old West ghost town.

Instead, it's a 184-mile stretch of water and wilderness

known as the C&O Canal.

I would say you've got me. I have not heard of this before.

-Did you just stump Jess? -I got you!

-Yeah, you got me. -Wow, that's tough to do.

This is a place that a lot of people don't know about.

And a lot of these haunting stories there have never been investigated.

But, ghosts or no ghosts,

this canal is a terrifying slice of American history.

1785, Mount Vernon, Virginia.

With the bloodshed of the Revolutionary War behind him,

General George Washington sets his mind to bringing trade goods inland

from the Eastern Seaboard to ports along the Ohio River.

First, he must improve the navigability of the Potomac River.

Washington enlists a workforce that hand-digs a series of canals that run parallel

to the Potomac to skirt five treacherous waterfalls.

1825. President James Monroe signs a bill to pick up where Washington left off.

The new plan is to build the Chesapeake and Ohio Canal,

which results in a massive 184-mile waterway

stretching from Washington D.C. to Cumberland, Maryland.

The price tag, $367 million in today's dollars.

But the real cost of the canal is the loss of hundreds of workers' lives

during its construction.

With a workforce often paid in whiskey and cigarettes,

drunken brawls and deadly riots break out.

Gruesome accidents and even cold-blooded murder are all too common.

1861. The Civil War.

More blood spills into the canal when over 200 Union soldiers are massacred

on the bank of the Potomac at the Battle of Ball's Bluff.

In the days and weeks that follow, ghostly screams and apparitions of soldiers

believed to be fleeing the battle are reported in the neighboring C&O Canal.

Operations on the canal ceased in 1924.

And today, almost a century later, paranormal encounters are regularly reported here.

Some believe it is the wandering spirits of slain soldiers that haunt the area.

While others are convinced it is the tortured souls of former canal workers

who suffered violent deaths.

The most recent sighting occurred only days ago

near an abandoned lock house on the canal.

There's this figure, just standing there, staring out at the water

and all of a sudden he turns around and looks at me with this stone-cold expression.

Then, he was just gone.

[Josh] Many believe these phantoms and the concentration of paranormal energy

are an echo of the C&O Canal's violent history

and the reason ghostly incidents are being reported to this day.

So?

Look, this is undoubtedly a fascinating time in American history.

And there was a lot of tragedy, there was a lot of death.

But this canal is along the Potomac River.

There's gonna be a lot of wildlife there.

So, when people say that they hear things or they see things,

I just wonder if those are all just cases of misidentification.

Okay, so you're telling me you think birds and deer

are being misidentified as a ghost.

Yeah.

What's the canal being used for today?

Not much. You know, the canal era obviously gave way to more efficient

modes of transportation and the C&O Canal was basically abandoned.

Except for the ghosts.

I've said it before. If you go someplace spooky

and you think you're gonna see a ghost,

you're gonna convince yourself that you're seeing a ghost.

And I've said it before, that ghosts appear where there is tragedy.

And this place was soaked in blood.

Your mission is to get to Virginia, get to the C&O Canal,

bring your enthusiasm, your skepticism, and see if you can experience

what people have been reporting here for generations.

-All right. We're on it. -Let's do it.

Happy hunting.

[Josh] On their way to Virginia, my team drives 238 miles

from New York City through Potomac, Maryland.

A town that, during the Civil War, played host to over 18,000 Union troops.

Today, it is one of the most affluent cities in the United States.

And the scenery as you drive along the Potomac is also, well, kind of perfect.

[Jessica] Well, isn't this a nice bit of Americana.

It is. It's beautiful out here.

[Josh] Running alongside the Potomac here is the mostly derelict C&O Canal,

which abandoned operations nearly 100 years ago.

I gotta admit, I had no idea this canal existed and it's kinda sad because

so many people put so much effort into building it.

-Yup. -And now it's just kind of in ruins.

Yeah.

The Battle of Ball's Bluff, that was what, 15 miles north of here?

Yes. What an unfortunate name.

What? Because of the "Ball's" part?

Yeah. Exactly because of the "Ball's" part.

-What else would it be? Not the "Bluff" part. -Real mature, Jessica.

Not the "Bluff" part.

[Jessica] We arrive on the Virginia side of the Great Falls National Park

near the site of the infamous Battle of Ball's Bluff.

With so many casualties, I think the spirits of the slain soldiers could explain

why many believe this area is the epicenter of paranormal activity on the canal.

So, we've arranged a meeting with Suzanne Trussell,

an archaeologist and consultant with the Allegany County Historical Society.

So she says she wanted to meet us at the top of the trail.

-Okay. -So let's get up there.

It'll give us a great vantage point.

We're hiking to an elevated perch that will give us a great view

up and down the Potomac River and would have provided an unparalleled scouting location

for soldiers during the Civil War.

-Suzanne. Hello! -Did I tell you I was scared of heights?

Suzanne's extensive study of the area's history, has revealed new evidence

that proves people have been reporting ghostly encounters here

since as far back as the Civil War.

-Well, Suzanne... -Hi.

I'm not gonna say this was the easiest place to get to.

I wanted you to be able to see the Potomac River here behind us.

Wow.

[Phil] Seeing this treacherous section of the Potomac River,

you quickly understand why they needed to build the C&O Canal to skirt around it.

And just upstream from here, is the historic battle site of Ball's Bluff.

This battle was a complete catastrophe for the Union.

[Suzanne] We now have two armies facing each other, separated only by a river.

They don't know how many soldiers each side has.

The Union Army sends a small troop over.

The problem was the river. They couldn't get reinforcements over.

Their commander, Edward Baker, was shot. And it was just pandemonium.

Men were just jumping over the edge and jumping in the water.

[Josh] On October 21st, 1861, the Battle of Ball's Bluff

saw more than 200 Union soldiers killed and almost 1,000 gravely injured

or captured while fleeing Confederate guns and canon fire,

with soldiers leaping off 100-foot cliffs, down to the rocky river below.

This has been referred to as as the most atrocious military murder

ever committed in our history.

[Jessica] Suzanne, you said you found something in the archives you wanted us to see.

Well, I have a soldier's journal here I want you to take a look at.

-Oh, nice! -There's an entry in there I want you to read.

It was written about a year after the battle.

[Jessica reading] "October 1862. We were sent on picket

on a strip of land between the Potomac and the Chesapeake and Ohio Canal

nearly opposite of Ball's Bluff.

Never were such weird sounds heard at this spot in the blackness of night.

Moans, groans, growls and screeches. Those men who were tremendously agitated.

Some of them heard the slashing of oars and strained their eyes

nearly out of their sockets to see who was coming.

There was something weird and ghastly about this place,

where so many good men were murdered, that almost stopped our hearts."

So he's reporting about people seeing and hearing ghosts.

-Yeah. -Do you believe that there's ghosts here?

People do report hearing sounds and feeling things.

So there's something that some people are picking up on.

Ball's Bluff is quite a spot in the landscape.

And the terror of just fleeing all Hail Mary outta there.

I could see where that would imprint the landscape a bit.

[Jessica] The Union soldier's journal proves that paranormal activity has been reported

here since the time of the Civil War.

And it coincides with a slew of recent reports from this area.

Our investigation will begin at the spot that potentially started it all.

The battlefield of Ball's Bluff.

[Phil] Well, should we hike up to the top?

After hearing more about the battle earlier today, I had an idea

and arranged for a surprise at the top of the bluff.

You know how you've been asking me to get more into this whole paranormal thing.

-All the time. -I decided to play along a little bit.

And I got us a trigger item.

-You did not. -I did.

-Did you really? -I did.

Oh, my God, you got us a canon?

Just like they used 150 years ago.

[Jessica] This is awesome.

-We gonna light this thing up? -Oh, my God, yes!

[Jessica] A trigger item is an object that might be meaningful

or have historical relevance

to the spirit you're trying to contact.

The fact that Phil is suggesting we use one, either means he's finally

coming around as a believer or he just likes to blow[bleep] up.

And now is the fun part. I need a charge.

[Jessica] If any spirits of fallen soldiers still roam this area,

the sound of canon fire just might get their attention.

So now, we're officially loaded.

Well, if this doesn't wake up the ghosts in this area, I don't know what will.

-All right, ready? -Ready.

Three. Two. One.

-All right, ready? -Ready.

Three. Two. One.

-Oh... my... goodness! -Holy crap!

I felt that in my, like, bones.

I'm surprised I didn't get knocked over.

Well, I think we've officially woken up any spirit for miles.

[Jessica] I say we head back down the ridge towards the water.

-Then see if this stirred anything up. -All right.

[Jessica] I'm hoping the canon fire triggers a paranormal response

from any Civil War soldiers that died here.

Near the water's edge, I conduct a call and response session

with a digital scanning device.

Paranormal researchers believe that spirits are able to communicate

through radio frequencies.

Is there anyone here with us right now?

[indistinct human voice on device]

Are you a soldier here?

[static on device]

Did you die during the Battle of Ball's Bluff?

If the spirits of slain soldiers are with us,

they're not making themselves known here on land.

I'm not really getting much.

So I'm ready to move our investigation to where

most of the deaths from the Battle of Ball's Bluff actually occurred,

in the water.

There's rumors of spirits all up and down this river, so what better way

to search for them but by floating down the Potomac.

Our destination is five miles down river to lock house 25,

a 200-year-old canal house where just a few days ago

a strange apparition was reported.

-All right, you ready? -Ready.

It's real heavy.

Come on, you work out.

As we travel south, we'll stay alert for any unusual activity along the river bank.

The soldiers that died during that battle, those bodies

floated all the way down the Potomac.

There could be any number of hauntings by the canal. Like, who knows.

Right here, look right here.

Oh, what is that?

[Phil] I think that's part of the canal.

Who knows what old equipment is left in there.

As the tide changes, they could be making some noises.

So what you're telling me is that the sounds that people are reporting hearing

of whaling and ghosts

in this area is actually old machinery.

I think it could explain some of it.

I am really glad that you said it explains "some" of it.

-Yeah. -But not all of it.

Let's turn on the night vision, scan the trees,

scan the shoreline, scan the ruins, and see what we can see.

Okay. All right.

All right, cameras. Let's go to night vision.

[suspenseful music playing]

[distant screaming]

Over there.

That was a scream.

Oh, yeah, that was a total scream.

And that was not the canal creaking.

Do you see anything through the night vision?

I'm not seeing anything.

I say we gotta get on shore.

Oh, it's about to come down hard.

[Jessica] Let's get our stuff on.

That scream sounded like it came from the direction of lock house 25.

Oh, check that out! Look at that!

Holy...

-Look at that. -I think that's it.

All right, let's find a way up.

-[Phil] Oh, my gosh. -Look at this place.

[Phil] Lock house 25 was originally built to house the family

who operated the adjacent lock

to allow cargo vessels to pass.

But this lock house saw its share of tragedy, as well as trade.

During the Civil War the residence was quickly converted

into a makeshift triage hospital and morgue for wounded and dying soldiers.

Today, this historic property has been preserved by the National Park Service.

This place is unreal.

We have potential Civil War soldiers that might have stayed here

or died in this area. I feel like this is what I wanna explore.

Well, we also know that right outside here,

people report hearing noises.

We heard for ourselves what sounded like a scream.

So I wanna get in the canal, see if I can just find some kind of explanation,

natural or otherwise, for what people experience here.

So you want to sweep the outside and I'll sweep the inside?

-Yeah, sounds good. -Okay.

[Phil] Next to the lock house is a portion of the canal that once contained an old lock.

These structures once allowed cargo boats to travel upriver

and navigate elevation changes.

Boats would enter the lock, the operator would close the gate

and the water would rise.

When released, the water would surge out and create enough momentum

to propel the boat forward.

Today the lock is in ruin,

a shell of its former self.

And I believe some of the strange noises people report in the area

could be coming from the wind or wildlife echoing inside this chamber.

Oh, [bleep], look at that.

Oh, my God.

Look at the size of that.

That is a huge snapping turtle,

which has insane bite force,

could easily take off a finger.

So I'm gonna be very careful when I'm in this water.

It gets deeper.

Okay. Oh, [bleep].

It's a leopard frog right here.

I guarantee you,

if this frog called out right now,

it would sound so weird in here.

Look at the walls of this place.

This thing is like a audio funnel.

The way it just shoots out noise and distorts it,

it just plays a trick on the ear.

And in a place with this much history, this much tragedy,

this many rumors of ghosts,

that could explain why people think this place is haunted.

All right, let's just get started.

Who is here?

Are there any Civil War soldiers in this home?

We're getting something, but it's so faint I can't tell what they're saying.

What's your name?

Oh, my God.

Daniel, are you a soldier?

Did you die during the Battle of Ball's Bluff?

Did you work on the canal?

18 years.

It said "keep moving."

Do you not want us here?

Whoa. [bleep]

That was downstairs.

It said "keep moving."

Whoa. [bleep]

That was downstairs.

Whoa, whoa, whoa, whoa, whoa! [shushing]

What the hell was that?

Hear it again, hear it again.

I kid you not, it sounds like there are footsteps here.

I don't know what's going on down here.

Oh!

Something moved.

God, this place.

Okay.

Whatever I saw out of the corner of my eye was likely just an animal,

but I'll admit, it got my hair standing on end.

Oh, look at this.

Oh, [bleep].

We have an entire tunnel.

I can't even see the end.

[Jessica] For a few months, this was a field hospital

that tended to soldiers with gruesome injuries,

which in most cases proved fatal.

I follow the sound to the basement,

a place that back then was filled with the dead.

This is definitely where the bodies were kept.

[static on device]

Daniel, are you here?

[Phil] I really want to figure out where this tunnel leads,

because I have a feeling this thing goes underneath the lock house,

and in my mind, that would explain so much of what people are hearing.

So...

Oh, it's cold.

Holy [bleep], there's some big spiders in here.

That's huge.

Hey!

[static on device]

If you're there, let me know.

[bleep], my God, something touched me.

Holy [bleep], I'm out of here.

It's getting pretty deep.

I found the exit, okay.

Oh, my gosh.

You see that?

That's the house.

I just went underneath the house.

-Jess. -Phil.

Oh, my God. I totally got pushed by a ghost.

Uh, what?

I was down in that basement and something totally like checked me.

-Come on. -Yes.

-Come on, Jess. -Yes, I got it all on tape.

What happened with you?

Well, for one thing, I got inside the canal,

sounds just bounce around so weird down there.

Additionally, I just crawled underneath the house.

What? No, you did not.

Noises bouncing around underneath the house

could make you hear something in the house.

What do you think you're dealing with inside there?

I don't think we're dealing with Civil War soldiers.

Oh. Why not?

I specifically asked,

"Are you a Civil War soldier? Were you part of the Battle of Ball's Bluff?"

No response at all.

The minute I said,

"What was your name and how long have you worked here at the canal?"

I got "Daniel" and "18".

Okay.

[Jessica] After a long investigation,

we return to the boat and head upriver.

The spirit that called himself Daniel didn't identify himself as a soldier.

So I'm left wondering if the paranormal activity along the canal

is a result of the canal workers

who died from the intolerable work conditions.

As a new day dawns, we're greeted by a message from Josh

asking us to check in.

Hey, Phil and Jess, what's the 411 on the C&O, how's it going?

I went in the canal, I went in some of the old tunnels and I've just been finding

that the acoustics play some really weird tricks on you.

So I've really been leaning into that as an explanation for some of the moans

and creaks and screeches that people are hearing.

But then, on the other hand, Jess had a brush with something.

I was doing a call and response in the lock house basement,

something slammed into me.

[bleep]. Oh, my God, something touched me.

-Oh, you mean literally. -Literally.

You're not the only person to have experienced something like this.

There was another encounter that a woman had

about 100 miles north

just recently

at a very infamous location known as the Paw Paw Tunnel.

Another person claimed, uh, that they had an attack.

Well, I'm not claiming, because mine happened.

I believe you, and you, I think, have to get to this tunnel to investigate.

Yeah, we're on it.

[Josh] With no time to lose, I've arranged a helicopter

to take Phil and Jess to the Paw Paw Tunnel,

so they can meet the new eyewitness before nightfall,

because she's scared to talk near the tunnel after dark.

And since the team wants to focus on the former workers that died building the canal

they can finally see the scope of what those laborers built.

We're travelling about a 100 miles northwest

from the site of the Battle of Ball's Bluff where we were last night

to the Paw Paw Tunnel,

just over half of the canal's total length.

[pilot speaking]

[Phil speaking]

For the construction of the C&O Canal,

the Paw Paw Tunnel was a literal shortcut,

boring through over a half mile of solid rock

and constructed using more than six million bricks.

It has been called the greatest engineering marvel of the canal,

and with hundreds of men losing their lives, maybe the deadliest.

Over the years,

there have been countless reports of mysterious shadows

and disembodied voices emanating from inside the tunnel.

And just two days ago,

a local eyewitness claims she was physically attacked by an invisible force.

She's agreed to go on camera but due to the intense nature of her experience,

she requested we obscure her identity.

Hi.

Hi. Nice to meet you guys.

[Phil] Thanks for meeting us here.

That's the tunnel?

Yeah, that's the Paw Paw Tunnel.

[Jessica] So this is the spot

where you said you were attacked.

Yeah. I was

here with my friends,

and they had gone up ahead a little bit, so I was alone,

and I came into the tunnel

and I felt something hit me.

It felt like it was trying

to push me into the canal.

It felt malicious.

Did you see anything?

There was nobody there.

I mean, that kind of reminds me

of what happened to me in the lock house in the basement.

[Phil] Something pushed you.

What do you think that something is?

I don't believe in ghosts.

I, you know, I'm not sure what it was.

All I know is what I felt.

Thanks for sharing your story.

Thanks for listening.

Ready to do this?

-Let's go. -All right.

[Phil] Look at this place, like,

it is super dark.

-Yeah. -Very cold. Very creepy.

I just, seeing a ghost is one thing,

but that physical touch aspect,

it's just-- it's a little hard for me to believe.

Why? I mean, I felt something in the lock house.

That's true.

I actually think it's weirder trying to build this thing.

All those men down here...

-Yeah. -...in the dark,

trying to carve through bedrock,

and they had tons of cave-ins.

Yeah. I feel like that would--

-Oh, my God! -What the [bleep]?

All those men down here...

-Yeah. -...in the dark.

I feel like that would--

-Oh, my God! -What the [bleep]?

[Jessica] What was that?

Something just touched my leg.

Something touched your leg?

Jess, don't give me that look.

-Like-- -I'm just saying.

-Look, look, look! -What?

There's a bat right there.

Maybe it was a bat that flew by my leg.

And I got just a little bit scared.

Oh, just a little bit scared?

Maybe more than a little bit.

[Phil] Look at all this water.

[Jessica] See, water's obviously seeping in from outside.

And if water's coming through, I wonder if some air

could come through, too.

During construction,

two sets of vertical shafts were dug out from the hill above

and plummeted 400 feet into the tunnel.

They were used for ventilation,

to haul rocks to the surface,

and to send supplies and bricks down.

And those shafts might be the key to explaining

all of the paranormal activity reported here.

Is that what you're thinking is making the noises that people are reporting?

I think the noises. It could explain

what pushed someone, too.

-There could be a shaft here... -Mmm-hmm.

...that causes wind to come out of this

and then super uneven ground.

[Jessica] Yeah. You get freaked out, catch your toe and trip.

Yeah.

I'm not buying it.

Maybe it was one of the dead workers.

Phil might not buy the idea of a ghost attack, but I do.

So I'm pulling out all the stops tonight.

Here's what I'm thinking. Let's set up the laser grid.

I'll have this pointing out that exit on that end.

You have that one pointing out that exit on that end.

That way, anything that crosses in front of it

should set off these alarms.

So once it's set, you have 30 seconds to make it out of the tunnel.

Okay. Done.

We're dealing with a ghost that can generate enough force

to actually push someone over.

So it's possible, that it can produce enough mass to interact with a person.

If that's the case it will trigger these laser trip wires

and set off an alarm.

All right. Time to get out of here.

While Jess stays to commune with the spirits,

I'm headed outside

to see if I can locate any of the old shafts that might be

generating strange sounds due to air being forced in or out of them.

And I'm breaking out the thermal camera to help.

One way to detect

air from the tunnel making its way all the way up here

is by looking for cold air.

So anything cold

coming up from the tunnel

is gonna really, really stand out as a deep blue.

Is there anybody in this tunnel?

Were you a worker here?

Did you die here?

Oh, right here.

It's about ten degrees colder

than all of the surrounding area.

There's definitely an opening here.

Oh, I got something!

Look at this! Look at that.

This takes us exactly back to the time period

of when people were up here making bricks, sending them down below,

building out that tunnel.

I've located one of the old shafts.

Though it's 8-foot opening is now covered up,

I want to monitor the sounds reverberating within the shaft itself.

So I've created my own device.

A funnel connected to a stethoscope

which will amplify any sounds coming from inside.

Oh, my God.

Holy [bleep].

This is absolutely insane what I'm hearing.

That is wild.

This sounds like a moan.

Which, let's be honest, that's what people report hearing around here.

While I needed a stethoscope to hear it tonight,

it's possible the sound coming from inside the shaft

could intensify under different wind and pressure conditions,

making it audible without the aid of special equipment.

Is there anybody here with us?

Were there many fights amongst the workers here?

Were you angry about the conditions working--

[machine beeping in distance]

The clash between North and South was the deadliest conflict

in American history.

And as a result,

many Civil War battle sites,

including the location of the Battle of Ball's Bluff,

where Phil and Jess started their investigation,

now live on in paranormal infamy.

But it's a lonely and notorious field

in Gettysburg, Pennsylvania,

that many claim

is the most haunted.

While walking the grounds of this former battlefield,

visitors often report the malfunction

of personal cameras and cell phones.

Only to have them work perfectly again once they leave the area.

It's said that disembodied cries,

the sounds of horse hooves,

drums and gunfire

can still be heard echoing in the wind.

Some have even insisted

that they've seen the spirit of General Robert E. Lee.

Now, whether you believe in ghosts and the afterlife,

there's no debating that the storied battlefields of the Civil War

should forever be revered as hallowed ground.

Were you a worker here?

Were you angry about the conditions working--

[machine beeping in distance]

The alarm went off.

[panting]

Hello?

But I'm not seeing anything.

Let's do the ghost box one more time out here.

[static on device]

Was that you that set off the alarm in the tunnel?

Did you hear that?

Were you a worker here?

[gasps] Oh!

Were you part of any of the violence here?

[cracking]

[gasps]

Something just threw a [bleep] rock.

Phil. You copy?

Yeah, you good?

Something set off the alarm.

Ran out here,

starting using the ghost box,

asked a few questions,

and then something threw a rock at me.

And it happened right when

I said, "Were you a part of any of the violence here in the tunnel?"

All right, Jess. That is crazy.

Why don't you come down here?

All right, sounds good.

[Jessica] So tell me what you found.

So I used the ground stethoscope,

and I swear to you, when I listened

to the earth, I heard what sounded exactly like a moan.

[faint moaning]

I actually think I was able to document

the sound of air passing through the hill.

So it could be coming out through some of these side bricks.

Do you think it could be coming out strong enough to push somebody over?

That's hard to say, but that's my best guess right now.

Did you hear any moans?

I didn't hear any moans,

but I did hear our alarm go off.

So something set off the laser.

We know there are bats in there.

Okay, one flew out.

[Jessica] It's possible, but

I'm still pretty sold on the response we got from the ghost box.

Right when I asked the question,

"Were you part of the violence here in the tunnels?"

a rock was thrown at me.

Do I think that there are the remnants

of that struggle

here that can be tapped into?

Yeah.

[Josh] The 184 miles that make up the Chesapeake and Ohio Canal

have become synonymous with paranormal activity.

While the team did not capture visual evidence of an apparition,

Jess believes she did make contact with something.

Twice.

[Jessica] It said "keep moving."

Do you not want us here?

[Josh] Phil heard mysterious footsteps while investigating...

It sounds like there are footsteps here.

...and seems to have been touched by something inside the Paw Paw Tunnel.

-Oh, my God! -What the [bleep]!

After analysis of the video of the laser grid in the tunnel,

you can see what appears to be a shadow pass through it

at the exact moment the alarm was tripped.

Could the shadow have been cast by a bat?

Or generated by a paranormal force, as some would claim?

Phil did collect compelling evidence that the ghostly moans

associated with the tunnel could be attributed

to the howling winds reverberating inside the mountain.

This is absolutely insane what I'm hearing.

[Josh] But knocking someone over?

That is less explainable.

The C&O Canal has seen more than its share of death.

And as paranormal reports continue to surface,

even skeptics like Phil are hard-pressed to explain away everything...

That was a scream.

...that is seen and felt...

[gasps] Oh, my God! Something touched me!

...along America's haunted canal.
