[narrator] Previously on Expedition Big Foot...
[Russell] I think there's something on the ridge above me.
[Russell] I believe the big foot to be an intelligent creature.
I believe it's going to be in the high ground.
Tactically, that's where you want to be.
[Mireya] This is actually the camera most interested in.
- [man] Yeah. - [Mireya] There it is.
I had tied it to that log.
Something grabbed it?
[Mireya] I can't assume it was thrown.
But Chimps in the field
are known to mess with cameras.
Why don't we try sending it to Bryce
and see if he can extract anything from it?
[man] Great idea.
[man] I'm on my way to talk to a preacher.
He was hearing some crazy sounds out of his backyard.
[man] This is the video.
[distant howling]
That's wild.
I'm really excited to get this out to the team in the field.
And hopefully they can play it over the loud speaker system
and get a response back.
Go for Mireya.
If you are ready to play that call,
- we are too. - Sounds good.
- Stand by. - [Mireya] Standing by.
- Here we go. - [howling over speaker]
- [bleep]. - Holy [bleep].
Ronny.
Tell me you heard that.
[Mireya whispering] They're tracking us.
One, two, three.
[Ronny] Put your light around it,
because if there is something up there
it's behind one of these big trees.
[Mireya] Shh, wait, wait, wait.
[narrator] In a remote corner of Southeastern Kentucky,
Primatologist Dr. Mireya Mayor
and researcher Ronny LeBlanc,
our hearing what they believe to be the movements of large animals
from three distinct locations.
[Ronny] What is that?
It's over here now, I think.
[narrator] On a cliff 400 feet above them
is survivalist Russell Acord,
who has also heard multiple sounds coming from different locations.
That was a really incredible sound.
I think one of them, came from this direction.
[Mireya] Let's keep moving this way.
[narrator] Ronny and Mireya decide to
cautiously move towards the sound
that they believe is closest.
[Mireya] There are certainly many more powerful animals out here than we are.
We have to take very slow, deliberate steps
beacuase we don't kno what's behind the tree, just a couple of feet away.
[Ronny whispering]
[Mireya whispering]
[Mireya] Ronny, why did you run?
That was so dangerous.
[Ronny] It sounded like it was right in front of me.
I had to chase it.
Wait, I recognize this.
[bleep] I think we got turned around.
What?
[Ronny] We're back to where we started.
I don't understand how we ended up here.
It's crazy.
This is really a first for me.
I don't get lost easily.
I have drunk jungles all over the world,
and I just... I don't get lost.
So many people talk about getting twisted up,
knowing the terrain or the area,
and then they get lost, they can't find their way back.
[Mireya] I don't know what was out there.
I know that there was one, in... From this direction.
One down there, one over there.
- Yeah. - [Mireya] And suddenly
it was disorienting, like we were surrounded,
and suddenly here we are.
I feel like they start just driving us,
making sounds so that we would come this way, then go around.
They just pushed us right back in a circle.
It's like they can mess with your head.
They're here.
They wanted us out.
And they did a great job of pushing us right back to that starting point.
I think the sounds have completely stopped.
Hey, Russ.
I think it would be great
if we could have you play another sound
to see just if we get a response
if we're any closer to it.
10-4.
[howling on speaker]
[Mireya whispers] I'm not hearing anything.
[dramatic music playing]
[Russell] It's been over an hour and a half
since we've heard our last vocalization.
It's gone completely silent.
We deployed the speaker system with Bryce's recording
of a new alleged Bigfoot howl.
The hell that we played tonight,
had we not played that,
very ulikely we would've heard a random howl.
It was responding to our initial activity.
It was loud in volume, heavy,
and it lasted longer than
oour lcould have put out that volume of the sound.
In all my years of research, I have never heard anything
that sounded anything like that.
Turned off the recorder.
[narrator] While the team hasn't located what was making the calls,
they are walking away with valuable evidence from tonight's hunt.
Russell's parabolic microphone,
designed to amplify even the faintest of sounds,
was recording the entire time.
[Russell] I think one of those sounds
is coming from the ridge right across from us.
I feel like I have a very, very good pinpoint of where it came from.
That is my next target.
I hope that I get the vocalization
as cleean as we heard it, 'cause that was impressive.
I'm gonna send this to Bryce to see what's on it.
There's a lot of info we can discover from what
what could be a genuine sound like this,
from IDing the animal to tracking its distance.
And who knows what other findings we get from this recording.
[Mireya] Hey, let's walk this way.
[Ronny] Everything all right?
[Mireya] Um, no.
What was that stunt you pulled last night, man?
[Ronny wispering]
[Mireya] You think there's a big foot there... [Ronny] Mmm-hmm.
[Mireya] ...and you charge at it. [Ronny] Mmm-hmm.
I mean seriously, what... What was that about?
Here's my reasoning.
This has been a passion my whole life.
I've been looking for this thing since I was a kid,
and at that moment I felt like it was right over that ridge.
And I wanted to have that face to face encounter.
So it was one of those moments where I was just impulsive,
and just charged forward.
Yeah, but this is not like an intuition... passion hunt.
This is a scientific expedition.
Tell me the story of when someone has charged at a Sasquatch.
No one. That's why I want to try new things.
I want to do different things.
I want that face to face visual confirmation.
I understand. But that is something that
if there had been a really large animal, there
It could've not just injured you, it could've injured me.
And that's where I take an issue.
[Ronny] Okay. I can get that, I get that.
Like we can't just do it like that man.
If you had been on one of my expeditions, you've have been gone.
I'm really sympathetic to the fact that
Ronny has been waiting for this moment his entire life.
But on a scientific expedition,
you cannot let your emotions overrun you to the point
where you risk making a scientific discovery.
It was just a stupid move.
We all want evidence out here, but what I'm looking for
and I think what you're looking for too
is objective evidence.
Something that we can take to the scientific community
and really prove that this exists.
- [Mireya] That's irrefutable. - Right. You're right.
[Ronny] Mireya is leading this expedition
from a scientific standpoint and I'm learning from her.
But when it comes to big foot and it comes to sasquatch,
there's things that I do that are unorthodox.
I want to have a class A sightiing,
something that I can show to absolutely prove that
they are real.
Apologies, I'm sorry.
I get it, dude. You were excited.
Wanted to see it.
[Bryce] So Russell just sent me the sounds that he recorded last night.
I'm going to have those analyzed,
but first, we're pretty excited to check the SD card
to see if we can find out
what exactly moved this trail cam.
[narrator] Two days ago, Ronny and Mireya discovered
that a trail camera they had placed
near a water source had been tampered with.
Bryce has picked up the camera,
and will be getting his first look at the images
to try and determine if they reveal how the camera was moved.
You know, these things are able to withstand
rainstorms and harsh environments.
That should be fine.
All right, here we go.
Obviously, this is when they set it up
and, uh, it's triggered during the daytime.
It's staring right at the pond.
Let's see if there's anything on here
that shows us how this camera ended up in the water.
These spikes just look like hair to me.
I mean, this just looks like an animal
with either hair or fur
that was extremely close to the camera.
What the hell?
All right, here we go.
[narrator] In a remote cabin deep in the heart of Southeastern Kentucky,
researcher Bryce Johnson is about to get his first look
at what caused a trail a camera to fall in to a water source.
Obviously, this is when they set it up,
and, uh, it's triggered during the daytime.
It's staring right at the pond, which is water source.
So it's a perfect place to catch something getting a drink.
But then we go to night time...
Wow, it looks like something is obstructing the lens,
and and I want to say it looks like hair.
Whatever animal this is
it triggered this infrared light
and snapped a photo of something
very close to the camera.
And these spikes looks like hair to me.
Now, looking at this next photo,
I mean, I could see movement here.
Something's moved the camera,
which is why this seems to be bleeding and obscured
Boom, now we're inside the pond.
This is s hot of the rocks at the bottom of the pond.
It's the strangest thing
to see our surveillance devices relocated by something.
I guess it could have been a bear toying with this
and then moving with it over to the pond.
But why would a bear tear a camera from a log?
There does seem to be a story.
You have to imagine that
the camera's gonna be triggered and captured
whatever or whoever the culprit is.
But it's not the first time
we've come across something that confounds us,
and leaves us with more questions than when we started.
Hey, Bryce.
[Bryce] Hey. So I was able to pull those images
of the trail camera that you guys found in the pond.
Whatever moved this trail camera tells a story of this thing being
possibly toyed with, or maybe even thrown into the pond.
While I can't be certain, it looks like it has hair.
[Mireya] Wow Bryce, that's crazy.
As a scientist, I naturally adhere to Occams's razor.
It's the principle that the simplest answer is usually the correct one.
I assume the log merely slipped into the water
to hear that that is not the case...
is really perplexing to me.
Well, that was in the same area
where something sprinted right past me.
Holy [bleep].
Just heard something really big running past me.
You guys are obviously very close to what we're looking for.
So just stay on track and, uh, keep your eyes peeled.
-[Mireya] All right. Thanks, Bryce. -Thanks, Bryce.
[Ronny] I dismiss that this was
any other animal, but a Bigfoot.
What else aside from a human being,
is going to be throwing a trail camp in the water?
Well, that's wild.
- [Ronny] That is crazy. - Yeah.
[Mireya sighs]
[Russell] I just need to get to the top of the next ridge line.
Last night's audio was amazing.
We got different sounds throughout the Valley
and from different areas.
One actually stood out in my mind.
There was no echo involved in it.
It sounded like a sound directed towards me.
I feel like I have a very, very good
pinpoint of where it came from.
And that's the ridge directly opposite of me.
That is my next target.
[narrator] Russell's plan is to ascend the mountain,
where he believes the possible
Bigfoot vocalization originated.
But the trek will not be an easy one.
[Russell] There's really no easy way up this ridge
without taking valuable time away from this expedition.
The only way to get to that point is a straight up the side of this ridge.
You do have the dangers, but at the same time
we're going to go where the evidence takes us.
[Mireya] All right, let's head back down this trail.
[Ronny] Okay.
So the call blast that we had sent out last night
was a real sasquatch call from the very close to this area.
And we got a response.
Sounded like there was possibly up to
to three different animals that were around us.
There was a ton of activity,
but we had no visibility last night.
So the idea this morning, the game plan is to go out,
scour this whole area and see if we can find
any type of tracks hair, tree breaks,
any indication that will confirm that they were here.
And I firmly believe that we were visited last night by several of them.
[Mireya] This is about where we were.
Vocalization here.
We had a... Sounds, what souded like footsteps and tree breaks up in here.
- And then some more down hrere. - [Mireya] Yup.
There's so much area here to cover,
I feel like I wanna go this way.
- Okay. I'll go this way. - All right.
[Ronny] Okay.
[Mireya] Even though it was so dark last night,
I specifically remember walking down,
uh, this riverbed that has dried up,
so I know that I'm looking in the right area.
If there were, in fact, three big creatures
surrounding us last night, and it is a primate.
Most of the time these animals
live in highly social groups.
And group living animals use communication as a way
of letting each other know whether there's a predator.
But in the cas of Chimpanzees...
Chimpanzees are the only primate species
that will have organized, coordinated hunts.
If we were dealing with three individuals out here,
it's impossible to say
what they were trying to communicate to each other.
[Ronny] I'm looking for something that's above ground.
That's eye sight.
That would be kind of like road signs
for other sasquatch.
Something that just looks like it's interwoven
and something had to have kind of put it together.
I'm looking for those type of structures.
So this is still rooted in.
It just fell down.
If this was pulled out and broken off and placed here,
I'd look at this a little bit more closely, but...
same with this.
You can see all the rot.
- [Ronny] Hey, Mireya. - Yeah.
I'm having no luck up here.
You find anything?
The only thing I found on there were out prints.
This is all I've found so far.
But other than that, I'm not coming up with anything.
[Ronny] Same.
Wanna regroup?
Yeah, let's regroup.
Sounds good.
[Mireya] It's really frustrating,
given all the activity we heard out here last night.
There's no physical evidence.
But last night, when we were hearing the holler in the low lands,
Russell was set up up top on the ridge line.
And so he was recording
all the sounds that we were hearing.
Hopefully, he got a good enough recording,
that he consent that to Bryce,
and we'll be able to analyze that.
[Russell] Let's do it. Let's just get up there.
Ready for it?
[narrator] Half way to the top of he ridge line,
Russell is encountering treacherous terrain,
which is starting to slow his ascent.
[Russell] Can you make it up on that rock and on that stump right there?
[Russell] Okay.
[Russell] Yeah.
[Russell] Okay.
[Russell] Ready for it?
[Russell] This is a steep one.
Are you good to do this climb?
[Russell] All right.
The incline is particularly steep.
It looks treacherous, but this is where we have to go.
[Cameraman groans]
[Russell] Hang on. Hang on.
[Camerama] Oh, God.
[Cameraman groans]
[Cameraman] Oh, God.
[Russell] Hang on, hang on. We just lost cameraman Zack.
Oh, [bleep].
[Cameramn panting]
[Russell] I think we need to get you assessed
before we go too much further here.
[groans]
He took a pretty bad hit on these rocks.
He can't put any weight on his left leg right now.
[Russell] All right, hold on.
We're going to help get you out of here.
[Russell] He's going to help get the camera guy out of here.
That's one badass cameraman hit the ground.
That's heartbreaking right there.
Sadly, he messed up his thumb, and shoulder, his, uh, knee.
[grunts in pain]
Going to get some medical attention.
I'm sure they'll want to x-ray it or MRI and it turns alright.
[man] This terrain is no joke. People get hurt.
[Mireya] Check it out. It looks like an old road.
There's all these gas lines all around here.
This must be an active mining area.
But the great thing is that it creates these inroads
that the animals can likely use as game trails.
[narrator] Below the hollow, where the team heard the mysterious sounds,
they've discovered a mining road
that runs east to west through their target zone.
[Mireya] This road runs right below where we heard those sounds
and the animals use these roads as well.
So it's a great opportunity for us
as we trek, trying to find that next holler
to see what is in and around this area.
[Ronny] This could be a great place for us to try to get some tracks.
There's some here.
- Uh, what you got? - There we go.
You've got some deer tracks there.
And then, over here...
There's a bobcat print there.
The surface area is much closer to the toes than with the coyotes.
So you've got bobcat there and deer prints right there.
[Ronny] Deer is a big food source for sasquatch
so that's a great thing to see.
This is the kind of thing we should be looking for.
Follow the animals, like which way are the animals headed.
- All right. - Yeah, let's keep looking.
So I'm on my way to talk to a lady who grew up in this area her entire life.
And she came across footprints just last year,
and she managed to take some photos of them.
But she was a little hesitant to talk about over the phone.
So I'm gonna go talk with her, see what she has to say
and see how it could help our investigation.
- Hey, Jenny. - Hey.
- You want to take a seat? - Yeah, I would love to.
Let's chat.
So, Jenny, you told me you experienced some strange things in this area.
Would you be willing to tell me a little bit about that?
What are you feeling?
A little hesitation.
Um, a flood of emotion, bringing back things.
My best friend, growing up, used to live right up on the edge of the mountain.
And we had some pretty interesting experiences as kids
that really throws for a loop growing up.
We got chased out of the woods once.
So you said you got chased out of the woods by something?
We had decided to go on a little hike up the woods
and her older sisters were in front of us.
So there was four of you?
- Exactly. - Okay.
I'll never forget it for the rest of my life.
I look over and her sister has this look on her face.
Just frozen with fear.
And there's something tall and black
standing just off from a tree.
Could it have been a bear?
No.
How tall was this thing?
Tall. I had to look up to look at it.
And it was big.
It was at least seven feet.
I remember the sound of it coming after us.
It's because it actually turned and looked at us and opened it's mouth.
The teeth on that thing was unreal.
That's the point where we just ran for our lives as that thing came after us.
[Ronny] So it chased you?
It chased us out of the mountain
and waited to stop until we were inside the house.
What about the face?
- You said you could see teeth? - I could see teeth but that was it.
There was a silhouette, and it was dark and black-ish.
I don't even like to really talk about it,
because the terror that we felt that day is stuck with us.
[Bryce] The amount of emotion it brought back in her,
having her think about that thing that she encountered
when she was just a little girl.
You know, there's sort of a lot of anomalous experiences
that people have been telling me about,
and perhaps this leads to a story of
something stranger going on in these woods.
What do you think is going on up there?
You think it's more primate in nature or?
I think it's a type of ape.
You know, once or twice a year, me and my boyfriend,
we try to go up and inspect some trails
- to make sure they're still passable. - Mmm.
Two and a half miles into the trek,
There's a print. Plain as day in the mud.
And I said, "Tony, come here."
"Are you seeing what I'm seeing?"
Oh wow,
Two and a half miles into the trek,
there's a print, plain as day in the mud.
And I said, "Tony, come here."
"Are you seeing what I'm seeing?"
- Yeah. - So, that's my foot.
And it keeps going forward.
And this isn't a human.
This is an animal, and I'm like, "This is huge."
- In the end... - This one to me is the big toe
and I mean something made an impression there.
And the stride on this,
whatever this was, was pretty big.
- It extends 5 feet out from the other one. - Wow.
And when we really got to look at it.
It looked like there was another footprint inside of that footprint.
- A smaller footprint inside one of the bigger one? - Yes.
And if you look really close right through here,
maybe there was something stepping in the side of the tracks.
Yeah.
You ever notice, deer, the fawns stay really close to Mom?
And I was like, "Could this be baby that is following their mother?"
I think we often misinterpret that there's only one of these creatures in the woods.
But you know, a lot of the times people report them as family units,
and that means younger ones.
You know, our team recently encountered multiple howls from different locations.
Is it possible we're tracking a family unit out there?
It makes you wonder, with all the caves
and outcroppings, who knows what's in here?
You really have to wonder if, with all this land that's undeveloped,
there could be species of ape around here easily.
- That could thrive. - Mmm.
And probably never be seen.
I brought a map. Do you think you might be able to point out near the area
- where you had some of these experiences? - Sure.
You're probably gonna want to look in this area right through here.
It's a little alcove down in here.
I think all evidence is leading to this area around Pine Mountain,
NARRATOR: which surrounds about half of our target zone.
And after hearing Jenny's stories about the things that she experienced,
I'd love to go up there and check out the area myself.
I want to know if I can get more information
as to what she was talking about.
Let me ask you this, do you think that creature
that you saw when you were young is still in these woods today?
Yeah.
My camera guy, Zach, took a pretty good spill
on this rock here behind me.
He was trying to climb up this rock.
He's got a camera in his hands trying to stay with what I'm doing.
He got hurt pretty good, messed up his knee.
So we got him some medical attention and see what happens with him.
He actually got on top, lost his footing, slid,
and he fell all the way down this rock.
That's a long ways down.
Not a good place to fall.
I have to be a lot more careful.
[narrator] Without a camera man,
Russell will film himself as he climbs the nearly three thousand foot peak
to where he believes he heard the howl originate.
[Russell] Uh, period, the terrain isn't easy.
It's steep.
The rocks are slick.
I've lost my camera guy, so I'm gonna have to proceed with caution.
Move a lot slower...
[rustling]
The heck is that?
Something big on that ridge just above me.
So I just heard what sounded like a bull, running down the hill towards me.
It was, um, I don't know,
maybe three hundred feet above me.
[whispering] I'm going to get up inside and see what I can find.
I've got some kind of treacherous stuff to get through.
I better shut off the camera for a second. Talk to you over there.
No sense in taking a chance.
I'm right up in that area where I heard that sound.
I'm not seeing anything, but it was close.
It can't be that far away. I'm going to keep going.
Oh, wow.
Check out this cave.
I've always suspected caves as being the habitat for Bigfoot,
and it's in the direction I heard the sound coming from.
I'm gonna take a look.
Let's see what we've got.
It is possible this could be a bear den.
Either way, I have to be extremely careful.
It's never safe to corner an animal.
Well, there's nothing in there.
That opening does look small and shallow,
but a large animal could have got inside there.
Other small entrances in the area have actually led to a giant caverns.
But whatever that sound was, it's gone now.
It's getting late.
So if I don't get a tent up, I might be trying to put it up in the dark.
Gonna go ahead and get away from this cave here
and find a better spot to camp.
[narrator] Eleven miles from Russell.
Bryce is near the top of Pine Mountain Ridge at the location
given to him by a local eyewitness.
[Bryce] So I'm up here,
righ where the spot that Jenny pointed to on the map.
The same place where she told me
she had that horrifying encounter when she was a little girl.
I'm near the place where she found those tracks.
So creepy.
There's a fence here.
There's kind of an opening up here too.
Wow...
I wonder why this is fenced in like that.
What is this?
Looks like a really old grave marker.
It's weird because I'm literally in the middle of nowhere.
And, uh, I'm not one hundred percent positive
that's what this is, but it certainly sort of looks that way.
This could be so old.
There are some people who believe Bigfoot
shows up around graveyards and places with a dark past.
It reminds me of last year when Ronny and Mireya came across
that hidden cemetery deep within the forest of Oregon.
[Mireya] Cemetery?
[Ronny] Cemetery in the middle of nowhere.
[Mireya] What the hell happened out here?
All I know is I don't want to spend too much more time here
walking over these graves, if that's what they are, so let's go.
[narrator] This place is just teeming with bugs
and life and old abandoned mine roads.
[Bryce] That really sounded like a woman screaming.
[Bryce] All I know is I don't want to spend too much more time here
walking over these graves, if that's what they are.
[narrator] At the southeastern edge of their target zone,
Bryce is investigating the area where
a local witness encountered, what she believes was a Bigfoot.
[Bryce] I mean, this place is just teeming
with bugs and life and old abandoned mine roads.
[faint screaming]
[faint screaming again]
It sounded like a woman screaming but almost animalistic.
That could be anything, right?
But, this is right around where it should be.
As scary as this is, I just...
I want to see what made that screaming sound,
- so I'm just trying... - [twig snaps]
That was close.
A big branch broke about fifty feet that way.
- [clicking] - My light just went out.
Holy [bleep]. Hold on.
My tactical light just completely went out.
I don't know.
It didn't dim out or anything.
It just completely died.
Uh, I don't have any explanation for it,
but I'm out of a light right now,
in the complete dark.
- [clicking] - [bleep]
So I'm gonna have to use my handy cam as sort of the only light.
I'm just gonna have to hopefully use this camera
as a light source, which is not much.
[Mireya] There's a load of tracks over here.
-[Ronny] Yeah -[Mireya] Deer.
So there's definitely animals using these highways.
[narrator] Ronny and Mireya are investigating
the mining roads that lead east from the location
they heard mysterious howls.
[Ronny] Oh, look at this.
Cat tails.
I mean, I know that.
So many Bigfoot sightings seemed to take place close to swampy areas.
Who has has been sightings of them,
like looking under rocks for different food sources.
So frogs, tadpoles.
So, what is it about the cattails?
They're reported to eat those?
Yeah, so they seem to be another food source
that the people have seen them chewing on
or found evidence that they were eating them or taking them.
[Mireya] Generally, when I've been in the field and looking for an animal
that eats bamboo, they'll start eating the stock,
- and then they cast aside what they don't finish. - Yeah.
Why don't we check out this area and see if we can find
any evidence that it has been eaten recently?
- Sure. Yeah. - Or that something has gone in here to eat it.
Okay.
Hey, Ronny.
- [Ronny] Yeah. - Come take a look over here.
[Ronny] What have you got?
[Mireya] Right here.
One, two, three, four, five.
And then you've got...
- No, this... - Could be the back of the heel here.
[Ronny] Is this a bear?
Definitely not a... Not a bear print,
[Mireya] But, initially, I thought
it might have been made by one of our shoes.
But look at how smooth this is.
Yeah. There's no tracks or anything.
[Mireya] I'm gonna photograph it.
[Ronny] Okay.
[Mireya] I see toe prints, defined arch
and a hell indentation.
Whatever it is, something large has been coming through here.
[Mireya] Oh, yeah. One, two, three, four, five.
- And then you've got... - [Ronny] No, this...
Could be the back of the heel here.
Is this a bear?
Definitely not a... Not a bear print.
Interesting.
[narrator] Along this secluded mining road,
Ronny and Mireya ave come across
what appears to be a massive footprint.
So Mireya just spotted this Interesting...
Looks like a track. Looks like a heel. You want to point it out?
- This is the heel. - [Mireya] Right here.
And then what looked like five indentations here.
[Ronny] Right.
[Mireya] And some sort of an art shape here.
[Ronny] She was thinking initially it's a boot.
But we don't see any tread.
- All smooth here. - Yeah.
And guess what's right over here.
Right near where this track was found
was a huge amount of cattails,
which we know is a potential food source for Sasquatch.
Definitely looks like the Earth is dried here.
Any way we can tell how old the print is?
[Mireya] It hasn't rained in the last few days.
- I suspect this area would be washed away with the rain. - [Ronny] Right.
[Mireya] So I would say it's relatively fresh trucks.
There's been a truck through here, so if there was a second track,
it's incredibly likely that it got run over by the tire.
[Ronny] It's still a great find.
[Mireya] We'll collect dirt from this area
on the right side of the print.
One of the things that we can do to rule out what it isn't
is to take a dirt sample and conduct an eDNA study.
If anything that stepped through this area, it's environmental DNA.
[narrator] Environmental DNA is the genetic information,
an organism naturally expels.
Analyzing this trace evidence is a revolutionary new technique
which allows researchers to sequence the DNA of a species
long after its departure from the site.
Right now, this is the best piece of evidence we have while we're out here.
So we need to investigate it as thoroughly as possible.
I want to look at almost a screen shot of what is coming through here,
whether that's bear, deer or anything else.
Right now, I see toe prints.
Uh, to find arch and a heel indentation.
But without properly casting this, I cannot say
that it's out of the realm of human possibility.
This will tell us exactly what made this footprint.
We are going to cover up the print in case it rains overnight
so that we can come back tomorrow morning and scan it.
We're getting a step closer to getting the answers to what we're looking for.
Whatever made this print is a big animal walking in this forest.
Is a big animal walking in this forest.
[narrator] Next time on Expedition Bigfoot...
- [indistinct animal sqeaking] - [groans]
Sounded like two screams. Two yells of some sort.
There seems to be a distinct sound in this area
that no one can attribute to anything.
[Mireya] Its path was in this direction.
Whatever was coming through, that area was rather large,
leaving a trail that we could actually follow.
[Ronny] Let me ask you, does Bigfoot have claws?
Oh, wow.
If you stopped short of the claws,
it actually looks like the human hand.
In order to narrow down our search,
Bryce arranged for a computational scientists to come and meet us out here.
Let's see what's out there.
[crackling]
[Ronny] Whoa.
- [Mireya] Whoa! - [Ronny] Holy [bleep].
[speaking]
[Mireya speaking]
[Mireya] Ronny, take a look at that.
Holy [bleep].
What the...
