Mireya: Did you hear that?
That's where it is.
I tried to get to where the source of the sound
Was coming from, but it was just too vertical.
It was just impossible.
We brought a hair sample that russell found to dr. Meldrum.
Oh, wow.
Matches the gold standard for bigfoot hair.

I need someone who's familiar with the bigfoot world.
Ronny's gonna be a great asset to the team.
Ronny: Look at this thing.

Russell: Hey.
Narrator: Bigfoot, sasquatch --
In the past 50 years,
There have been more than 10,000 reported sightings
Of this elusive creature
In the continental united states.
From the ozarks to the mojave desert,
From the new jersey pine barrens
To the pacific northwest, every year,
Hundreds of eyewitnesses log their encounters.
But where or when this legendary cryptid will be seen next
Has been a mystery until now.
For the first time in history,
A team of investigators is using an advanced data algorithm
To analyze five decades of bigfoot sightings
To pinpoint when and where to encounter this elusive beast.
With the results, they now know the time and place to search,
And the greatest bigfoot hunt ever is on.

Primatologist dr. Mireya mayor and bigfoot researcher
Ronny leblanc are investigating what could be a bigfoot nest.
Is this typical from what you've seen? Yeah.
Seems to fit exactly what I've seen back east.
The spot is perfect to hide in here.
Narrator: In an effort to determine what could have
Constructed the nest,
Mireya is taking samples of the dirt
Below the mysterious structure for testing.
Mireya: If you want to lift that side of the bedding,
And I'll just take some soil from there.
Narrator: Living things constantly shed their dna
In different forms,
Like dead skin cells, saliva, and hair.
This is called edna or environmental dna.
A revolutionary new process called metagenomics
Allows scientists to scan the edna in a sample
And identify every living thing
That has come in contact with the area.
The amazing thing about environmental dna is that
It enables us to find
An entirely new physical class of evidence
That we didn't even know to look for just five years ago.
It's entirely possible that the key
To solving the bigfoot mystery
Has been staring at us in the face
From the very beginning.
This little sample could hold all the answers.
Oh, holy ****.
What is that?
About 6 feet from the nest.
Is that something that is typically reported,
Some sort of a kill nearby the nest?
People have been gifted feathers and things
Like that that are in certain hot spots.
When I went back to my truck,
I didn't believe what was happening.
Under the windshield wipers, I found hawk feathers.

Ronny: Native americans have talked about this gifting
As leaving an offering, a gift.
So it's a way of kind of communicating
And exchanging between sasquatch and humans.
Mireya: Let's document this for bryce.
Clearly something is unusual about this area
And this nest site.
It sounds like this very much falls in line
With previous nests that have been attributed to a bigfoot.
If this is a nest, there has to be more evidence nearby.
We're gonna go ahead and check just all around us

I was not expecting to find a bigfoot nest.
This could change the entire course of the investigation.
Look how fresh these boughs are.
This was done, like, a day or two ago at the most.
Bigfoots are known to make these nesting beds,
But this nest in particular reminds me
Of a discovery in california
In a place called marble mountain.
Narrator: In 2001, a youth ministry group
Was camping in the foothills of the marble mountains
In northern california.
After discovering a mysterious structure
Made of broken trees and pine limbs,
A giant figure appeared on the ridge.
Boy: I don't see nothing. Seriously.
- On the ridge. - On the ridge.
Right on the ridge.
Almost to those trees.
It's coming down this way.
Narrator: Some have called this 3 minutes and 45 seconds
The longest bigfoot video ever recorded.
I was able to get ahold of one of these kids.
He's no longer a kid now. He's actually an adult.
He's willing to talk with us about this video
That they took in 2001,
And he's agreed to speak with me.
[ computer chiming ]
Hey, ben. It's bryce.
Hey, bryce.
Thanks for taking the time to talk with me today.
Yeah, absolutely.
So walk me through it.
How did all this take place?
Yeah, so my dad was youth pastor,
And my dad just loved the outdoors,
And so we'd take kids on backpack trips
All time, still do.
Actually, my brother and I run the same ministry
That my parents were running at the time.
So yeah, we were up in this --
The marble mountains wilderness,
Which is up northern california near mount shasta.
Girl: Oh, it stopped, and it's looking at us.
My parents went off for a walk,
And they came back and they said,
"guys, you got to come check this out."
Man: Some kind of creature has taken and piled tons
And tons of leaves and branches to either camouflage
Or make a place to hide.
See how they're broken, snapped like twigs.
They're snapped like twigs, no hatchets,
No human marks of a saw.
Everything is snapped as though my mighty, mighty strength.
One of our team members found a nest as well.
And the similarities between this nest
And the nest that you guys came upon are striking.
I mean, that there's no cut marks.
There's no hatchet marks.
They're just snapped in half.
Some have even pulled apart.
So, ben, if you can, just walk me through that moment of, like,
After you see this huge structure,
And then I think it was you who said you pointed out
Something walking along the ridge.
So I'm the one in the video that says,
"hey, look. He's right there. Sasquatch is coming down."
- He's walking down. - Oh, my word.
Bigfoot is walking down right now. Uh-huh.
See, he's standing taller.
So you could barely see it,
And then when we got the camera on it
And zoomed in with the digital zoom,
Obviously it's pretty pixelated,
But you can see the shape a little better.
Oh, you can see the shape good if you ask me.
I mean, and I even hear some of your friends
In the background say it doesn't look human.
- That is -- - it doesn't look like a person.
- It does not look like a person. - It doesn't look like a person.
- No. - Its arms are way too big.

The possible bigfoot track
With layers of plastic sheets to protect it from the elements.
I don't know if this is a bigfoot track
Or the print of a bear that slipped.
The only way to know for certain is to just scan the track

There it is.
All right, well, let's pull out the scanner.
- The scanner, cool. - Yeah.
Narrator: To capture and analyze the print,
The team will not be using plaster of paris.
This method often used by bigfoot researchers is messy
And extremely time consuming.
Instead, they'll be using a cutting-edge technology,
3d scanning.
This scanner produces
A three-dimensional representation
Of a real-world object
By projecting patterns of light onto a surface
And then measuring the resulting distortion
To calculate the object's precise dimensions.
You want to move that computer a little bit, and I'll spray it.
Sure.
Narrator: To improve the accuracy of the scan,
Mireya applies an anti-reflective coating
To the print's surface.
This scanner is accurate to within.2 millimeters.

So it's plotting all the different sections here
And forming the footprint.
Also, grabbing everything around it.

While I'm doing that, though, I want to take a look at that
Sound recording that our team captured in the field.

Narrator: Just days ago, a team of sound engineers
Using a brand-new sound localization prototype
Recorded a possible bigfoot call.
Those sound files have just been sent to bryce.
These could be actual bigfoot recordings,
Which is a huge deal because there's really only
A handful of credible audio recordings of sasquatch
Within the research community.
Capturing a recording of bigfoot in our target area
Is suggestive of a sasquatch,
And that tells us that our data analysis
Has us looking in the right palace.
But here's to problem, this isn't a perfect recording,
So we have to analyze these and make sure
That these audio recordings come from an actual animal,
And not just a human making that howling call.
[ howling ]
So I have a contact who's an expert in sound design
And recording.
I want to get him this file in the hopes that he can isolate
This sound recording as well as clean up the file.
I also want to see if this recording contains infrasound.
Narrator: Infrasound is a powerful inaudible
Low frequency tone used by large mammals
Like tigers to ward off animals
That have entered their territory.
Many eyewitnesses have reported
Experiencing debilitating illness or paralysis
While in the presence of bigfoot.
If there is infrasound in this signal,
That will narrow down our window
Of the potential animals who use infrasound.
Let me tell you something, there's not a lot of them
In the pacific northwest.
No other animal produces infrasound in this region.
So if this signal does contain infrasound,
That's another important piece of evidence confirming
That sasquatch is in our target area.

I knew it.
I mean, that is right in the range of infrasound.
Our bigfoot call that we recorded has sounds
That are sitting below 20 hertz.

Which means there was infrasound which could help explain a lot.
When we lost r.P.G. That first night...
I don't know. I just -- I can't shake this one.
...I suspected it was due to the effects of infrasound.
Now I have derek telling me that he detected a bunch
Of low frequencies in that howl that mireya recorded.
We know that no other animal in our target zone

Russell: Well, I'm 6 foot.
I'd probably reach maybe another foot and a half,
Two feet over my head.
When we got there, this thing was massive in size.
You take the water source and add a high rub
Plus the sound I heard heading in this direction,
It could all be adding up to the fact
That this area is significant.
If bigfoot is territorial,
It makes sense that they would be marking
And laying claim to this secluded watering hole.

So our bigfoot recording had frequencies below 20 hertz,

In hopes of luring bigfoot out of hiding and into the open.
When you get the evidence that we've been getting,
The nest, the hawk, the footprint,
This is the time to let him know
That we're not here to harm them.
Bigfoot needs to get your trust, and the best way to do it
Is to create an exchange through the process of gifting.
Is gifting a common thing in the bigfoot world
Where people leave stuff and find stuff in return?
There's different camps.
Some people believe it's -- this is just hooey,
But I think that we should try everything we can.
Gifting is something that we observe in the natural world.
You know, gentoo penguins will use gifting sometimes.
They will give a rock, you know, to gain a mate.
But the idea that bigfoot is coming in to take this gift
And leave something behind, that is a really long stretch.
On the other hand, science sometimes does require
A nontraditional approach.
Ronny says he's had results this way before,
So I'm open to his suggestions.
Narrator: The area they'll be focusing on for this new tactic
Is the zone between the possible nest
And the location that
The suspected bigfoot vocalization was traced to.
Mireya: The plan is to go search between two points,
The nest and the origin of where the sound came from.
That makes sense because anywhere
That shows a sign of activity,
We have a much better chance of tracking them,

That r.P.G. Said that he was feeling, headaches,
Exhaustion just rolled right over top of you.
Narrator: Russell checks the trail cams
He hung around the area
To see if anything was spotted
After he had to shut down his nighttime survey.
Russell: There we go.
The only thing I'm seeing here is when I set it up yesterday.
♪♪
If that was an infrasound attack last night,
Then we're definitely in the right place,
And the possibility of a class-a sighting
Is increased dramatically.
I need to take another look around.
There could be some evidence of last night's encounter nearby.

Ronny: It's getting dark quick.
Narrator: As night falls, mireya and ronny make their way back
To the gifting sight to begin their stakeout.
So the plan tonight is just to go stealth,
Have all our thermals and high-tech gear.
Right. So we'll have the thermals,
So it's gonna give us a little advantage.
We can see a wide spectrum as we're coming through the forest.
You know, when we're on these hunts at night,
We want to go out there and reduce our light signature,
So we're going to be deploying thermal imagery
Which allows us to see heat signatures.
We'll use red lights. Hunters use this.
Animal life can't really see that signature.
When it comes to bigfoot research,
We need to be as stealthy as sasquatch.
♪♪
Just went dead silent.
Dead silent.
It's like everything in the forest just shut off.
That's weird.
♪♪
Russell: I'm back by my water source to see
If there's anything else here.
Narrator: Russell is patrolling the area
Where he encountered a strange sickness
While surveilling a water source just last night.
♪♪
Look at this.
♪♪
That seems kind of weird.
♪♪
We have a stump with a scapula on it
And a pine cone placed in the center.
It doesn't look normal,
As if everything was placed for a reason.
There's no natural way this bone would've ended up
In the middle of this stump directly in my path
As if being led right to this point.
If a predator feeds off of an animal,
There'll be other bones and other things in the area.
There's nothing in this entire area
Except for this one shoulder bone.
This could be a gift left behind for us.
♪♪
Narrator: Three hours into the team's stakeout,
There is no sign of activity.
So we're up on this ridge not too far from the gifting spot.
The idea is hopefully with the cameras set up,
We're gonna capture something.
We're gonna hang here as long as we need to.
♪♪
Listen.
Sounds in the distance, like, coming towards us.
Shh.
♪♪
Go.
♪♪
- Did you hear that? - Whistling straight ahead.
♪♪
Wait, stop for a second. That was another whistle.
That's twice we heard that whistle.
This falls in line with bigfoot, the fact they'll whistle.
No one really knows what they're communicating,
But it's believed that they're talking to other bigfoots
To warn them that we're in the area.
♪♪
Eyes. Oh, my god.
Narrator: Next time on "expedition bigfoot"...
There's a really serious smell through here.
It was a god-awful smell.
I turned and look and...
Take your time, man.
I'm already getting feeling that we're being watched.
The only way I guess I could describe it was, like,
You know you see horror movies.
[ bleep ]
It's something you don't ever forget.
And it's not something you hang around to see.
You get out of there.
