Narrator: Previously on "expedition bigfoot"...
Man: This is the perfect place to start.
Something up here.
Game trails? Oh, we definitely want to get eyes on that.
We have sasquatch's freeway system.
Something about 30 miles outside of the target zone,
I will be there, eye in the sky.
I'm really hoping to get some images that lead us to bigfoot.
There was a distinctive shift in the smells in the air.
It went from wet ground and earth
To something very, very nasty.
Large mammals use infrasounds to paralyze their prey.
Push too far into their territory,
You'll have one of those experiences.
Rpg, he's in really bad shape.
Unfortunately, I have some bad news.
We're not gonna continue the expedition with rpg.

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.
♪♪
- Morning. - How are you?
I'm all right.
Narrator: On the edge of the 90,000-acre target zone,
World-renowned primatologist dr. Mireya mayor
And bigfoot investigator russell acord
Are still reeling from the loss of a crucial team member.
I'm still in disbelief.
It's almost like he'd worked his entire life for this moment,
And to have to leave without that payoff, you know,
Or feeling like you made it to the finish line, that's rough.
Yeah, what a blow, huh?
Narrator: With data analysis showing just a three-week window
For the maximum probability of a bigfoot sighting,
The pressure is on investigator bryce johnson
To find a replacement researcher for the team.
So the doctors still haven't diagnosed a specific cause
For ryan's headache, but either way,
We have a man out, and I need to replace him.
This expedition was designed for three field team members,
And we have a lot of ground to cover,
So I'm gonna reach out to bob gimlin.
He's a revered legend in the bigfoot community,
And just about everyone on the planet has seen his film.
Shot nearly 50 years ago,
It's the most famous 59 seconds of bigfoot footage ever taken,

And it really just kicked off an investigation
Into the phenomena of bigfoot, and bob gimlin has been involved
In the bigfoot community ever since.
So if there's anybody I can trust to give me a referral
Or a recommendation for somebody to replace a guy like rpg,
That referral would come from a guy like bob gimlin.
[ computer chiming ]
Hey, bob.
Hey, bryce, mighty nice to see you again.
Likewise. How you doing?
Great, fine, thank you.
- Good. -How's everything going, bryce?
I had to rush one of my team members
To the hospital last night.
Oh, that's too bad. What happened?
While he was there, bob,
He started experiencing blinding headaches,
And he said they sort of just came on pretty rapidly.
I don't know. It's very strange.
I think whatever caused the headaches
Could've came from something like infrasound.
Have you ever had any experience with that?
A couple years ago, a fellow really got sick up there.
He had a direct encounter with one.
- Oh, really? -Yes, sir.
- What happened? -It came right up to his tent.
He couldn't even move. He just was incapacitated.
Yeah, that sounds exactly like what happened to rpg, and, look,
Hey, that's one of the reasons I'm calling you today, bob.
I need to find a replacement for him immediately,
And I was wondering if you might have anybody in mind.
Well, yeah, I can get you some names
And get it sent to you as soon as possible.
That would be great, and these are people you trust?
Yes, sir, good, trustworthy people.
Well, look, I don't want to take too much more of your time,

- Here we are now. - Okay.
Where were you in relation to this?
Okay, I was on this bend.
I really want to investigate that spot
Where I had got that smell from. Yeah.
Narrator: Last night, survivalist and big-game hunter
Russell acord caught the scent of something
He could not identify.
Deer, elk, bear -- they all have their own distinctive smell,
But I smelled something different,
Kind of a skunky smell.
- That sounds good. - Okay.
Then I am going to head back here. Okay.
This is where rpg and I went.
This is where we saw the game trails.
So we were able to basically set up some trail cams.
There was lots of activity.
I mean, we saw where it appeared
As if animals were running down this hill.
I'm gonna check on those trail cams. Okay.
And then there's an area right around here
Where I'm gonna try out these speakers
That play out, like, game sounds.
Among all the really cool stuff
That bryce brought in were these speakers
That hunters use to lure in predators,
And that's something that I have personally used out in the field
When working with wild animals.
I've recorded lemurs, for example,
And then I've played that back to make contact.
Bryce was actually able to load a supposed bigfoot sound,
A recording, and I'm gonna play that out there
And see if we get any sort of sound back.
So I think it's worth a shot,
And I have a good feeling about that spot.
Sounds good. All right, thank you. All right then.

With a circumference of 60 feet around his tent
And will alert him if anything approaches.

This is when animals start coming out and moving.
Narrator: Five miles north of base camp,
Mireya is closing in on an area where, along team member rpg,
She discovered high levels of animal traffic
And predatory activity, but tonight, she returns alone.
Mireya: Most animals are less likely to attack
If they're outnumbered.
Going in alone, there's more of a risk,
And so, because there are a lot of things that could go wrong,
You have to be really aware
Of all your surroundings at all times.
I want to head over that way and put out some calls
And see what happens.
Narrator: Mireya believes this is the ideal location
To attempt a bigfoot call.
Some of the methods that bigfoot researchers employ out here
Are actually not that different from my own research.
I've often made gorilla calls, and I've gotten a response back,
So based on ape behavior,
It's actually a really successful method.
So bryce loaded up a bigfoot recording on this.

Making calls is a huge part of bigfoot research.
In fact, some of the best evidence
That we have for the existence of bigfoot
Comes from vocalizations recorded in the field.
Most people, when they do it themselves, right,
They're pretending to be a bigfoot.
Tonight is gonna be different.
We're gonna be playing back a high-quality bigfoot sound
That was recorded just last year,
And I am extremely hopeful
That when we play this back over the foxpro
That we're gonna be able to elicit a response.
Narrator: The speaker system mireya is using
Has a top output of 118 decibels
Or the same sound level as a jackhammer,
Meaning anything within a two-mile radius
Will be able to hear it.
Mireya: This is reportedly the best time of night
To go hunting for bigfoot.
By me playing this supposed bigfoot sound out there,
That should elicit a response back
Because I'm an intruder in its territory,
And the territorial species will want to let you know
That you're on their turf.
You're facing an animal that you know nothing about.
There's no manual telling you that what you should do is stand
Still and hold your ground or climb a tree
Or run as fast as you can in the other direction.
It's an unknown, but if we get a response,
I'm going in after it.
That's what I would do in the field in africa,

If mireya is able to elicit a return call,
Its exact location will appear on the monitor.
If we hear something and we can pinpoint its location,
I'm going in after it.

Let's try again.

Should we try one more time?
- Sure. - Try one more.

Anything?
Well, what happens here is when these sensors pick up the sound,
They measure the difference in time.
Did you hear that?
Yeah.
You heard something.
- Yep, that way. - Yep.
Mireya: That was it. That was the sound.
Can you track it?
Reaching the sensors, reached sensor two,
Seven, three, five.
It reached all the sensors.
Narrator: The engineers run the software
To get the precise coordinates of where the sound came from.
Oh, there it is.
We got the coordinates.
I'm just trying to make it there before dark.
All right. Let's go.
I can feel you telling me about how visceral it is for you.
Is the memory still right there?
I can feel,
I can sense, and I could see everything
In crystal-clear clarity.
There's something so powerful about this bigfoot
That once you experience it,
And once you feel it and hear that roar,
You know in your dna
This is something so powerful
It could just rip you apart like a piece of paper, right?
There's just no way.

Narrator: Next time on "expedition bigfoot"...
Mireya: I never thought I would've heard something
That could be bigfoot.
What the hell have we just found?
Russell: We actually found this hair in a bird's nest
At the top of a 6,000-foot peak.
It doesn't match any other known species. Oh, my god.
It was just here.
It can't be that far away.
Hey.
Mireya: It feels as if this forest has eyes.
