[narrator] Previously on Expedition Bigfoot...
[Bryce] Our surveillance system registered a hit.
I believe these creatures are breeding
and possibly raising their young
right here in Northern California.
-Check that out. -[Mireya] You got a print there.
[growling]
[Bryce] Right there. Right there. Look at this.
You see that?
[Mireya] Bryce, Bryce.
[distant howling]
Oh, my God.
[Bryce] Holy crap!
Something is giving off the heat signature.
Look, look, look, look! It looks upright.
Holy [bleep].
[Bryce] The evidence that I've picked up along the way...
That looked like something walking down the hill.
Everything is piecing together.
[Mireya] OK, so now that's weird.
Something put this here.
This is nesting territory,
and we are right smack in the middle of it.
All this action is converging into one place
at the center of our hot zone.
I'm getting a heat signature.
[Bryce] All of our hard work has culminated to this very moment.
[Mireya] We started off this search with 7,000 acres,
and we have honed it down to one single mountain.
[Bryce] We are right at Bigfoot's front step.
We're closer than we've ever been before.
[reporter] A powerful storm system
is passing over Northern California.
The storm, fueled by an atmospheric river,
could dump up to five inches of rain in coastal areas.
And some snow in the mountain.
[man] It looks like that storm is closing in.
-[Mireya] Yeah, It's big, huh? -Yeah.
[reporter] Wind gusts can reach speeds up to 60 mph
and up to 80 in areas of higher elevation.
[Mireya] Hey.
-Hey, guys. -Hey, Bryce.
How's it going?
This is Kyle and Jordan.
-Hey. -Good to meet you.
When I say we brought out the big guns, I'm not kidding.
Nice.
That's amazing.
Now that we've established that this mountain
is these creatures' territory,
we've brought in the most incredible piece of tech
to help us pinpoint their exact location.
So we're able to run algorithms.
[narrator] To do this, the team will be using
a surveillance array of eight high powered optical
and thermal cameras covering the mountainside,
all driven by artificial intelligence
that can recognize upright, bipedal animals.
-Russ, you take one side. -All right.
And Mireya, you take another.
[Mireya] All right. Thanks, man.
[Bryce] I'll stay here with these guys
and we'll watch you as you move through the area.
[Russell] If anything moves on that hillside,
he's gonna be able to see it,
identify it, and direct us directly in its path.
This thing should work flawlessly.
[Bryce] There they are, right there.
-Mireya for Bryce. -Yep.
-I'm in position. -We see you right there.
- [Russell] Hey, Bryce. -Yep.
-I'm in position. -I got you, Russ.
Excellent.
[reporter] Officials are urging residents
to be ready for possible evacuations
in flood prone regions as the storm system poses
a significant threat to Northern California.
We will continue to provide updates
as the situation develops.
We've been watching this side of the mountain
on our surveillance array for a few hours now,
and unfortunately we haven't gotten any hits.
There's a bunch of possibly...
What is that... deer, maybe bear.
We've seen things on all fours,
but our software algorithm is set to look
for upright walking bipedal creatures,
which we haven't seen yet.
[narrator] While Bryce is the eye in the sky
watching the eight cameras
of the surveillance array, Russell and Mireya
are searching different locations
and elevations on the mountain.
The team has a small window of time
before storm conditions worsen,
which could limit the array's capabilities
of detecting anything
with the optical or thermal cameras.
-[machine beeping] -[Mireya] Mireya for Bryce.
Yeah. We see you on the surveillance array.
You can see me now in position?
Yeah. Visibility is a little bit limited,
but we definitely see you.
Great. Well, let me know what you're seeing up on that array.
We need to pay attention.
There's a lot of trees falling through here.
And the sloughing off the soil.
This is some steep, treacherous stuff.
Let's just be watchful.
Right now, with this weather,
things are getting a little bit sketchy.
We've got all this rain and snow coming down,
so the soil beneath our feet is pretty tricky.
What's with all these branches here?
[Bryce] There's Russ right there.
[Russ] Russ for Bryce, Russ for Bryce.
[Bryce] I hear you, Russ. Go for Bryce.
[Russ] You should be able to see me. Can you hear me?
[Bryce] Yeah, we do see you on the surveillance array.
Looking good, buddy.
Let me know if there's anything I need to pay attention to.
-Copy that. Stay safe. -Thank you, Bryce.
Hang on. Hang on. Hang on up the hill a little bit.
[Bryce] What the [bleep] is that?
[Kyle] We got a target here.
Came up from behind a tree.
That is not Mireya, is it?
That is not Mireya
[Bryce] What the [bleep].
Holy [bleep].
Hey, Mireya, the eyes
acquired a target coming up to you.
It's really close, I'd say about 200 yards
to the south-west, and it looks big.
Are you seeing anything?
[Mireya] I'm not seeing anything.
I'm gonna keep going in the south-west direction.
Keep your eyes on it and let me know if it changes direction.
All right, let's keep moving.
[Russell] I'm seeing a lot of...
...stuff in the soil, disturbances.
This whole area has been pushed up a little bit.
[narrator] As Mireya heads towards the heat signature
on the other side of the mountain,
Russell searches his target area.
A lot of stuff moving, right through here,
it's almost like a little hidden sidewalk here.
Holy [bleep]. I am getting something coming up on Russ.
Are you seeing that?
Yeah, it's big.
-What the hell is that? -It's fast.
Hey, Russ, we see a target
making its way towards you, and it is moving, man.
Are we looking downhill, uphill or in front of me?
In the direction of moving? Guide me.
[Bryce] It is to your east,
probably about 50 yards and moving in.
Got it.
Copy that.
Something's been through here just recently.
[whispers] Stop, stop, stop.
Are you... Can you smell that?
That's pretty strong.
Did you hear that?
Something broke branch out here in front of us.
Russ for Bryce.
Russell. I got you loud and clear, man.
[Russell] It just broke a stick out in front of me
less than 100 yards. How close am I?
[Bryce] If you stay that course,
you should be able to intercept.
Copy that.
Moving in.
[Mireya] It's just incredibly hard right now
with this terrain and this weather.
[narrator] Further up from Russell,
Mireya is descending the mountain
in pursuit of a large thermal image
spotted on the surveillance array,
heading in her direction.
[Mireya] It's like an obstacle course, isn't it?
Hey, Bryce, I'm trying to run down
towards where you saw that heat signature.
[Bryce] Gotcha, Mireya.
I got a target right here.
Oh, yeah, we definitely got a target.
[Bryce] Holy [bleep].
Hey, Mireya, we're picking up two targets,
not just one.
Are you hearing or seeing anything?
I'm not seeing anything.
We're losing that other signature
between the trees and the fog,
but if you just keep moving,
you shouldn't be able to connect with it.
[Mireya] Roger. I am heading towards them. Over and out.
Well, I'm trying to see if anything that's moving
might be moving up in this direction.
The problem is, all the elements
are really working against us right now.
This is incredibly steep, it's slippery,
and we can't really hear as things move through the forest
because of all the rain and the hail.
We're really starting to lose them out here.
This is making it impossible to see anything.
[Bryce] Yeah, coming in really bad.
The weather has been all over the place,
and now we're getting these waves of fog
rolling through the mountains.
If it gets any thicker, this system
won't be able to detect anything.
Hey, Mireya, uh, we just lost that signal.
[Mireya] Bryce, I didn't see-- But I'm not--
[bleep] You're not coming in.
[Mireya sighs] It just gets hairier.
Oh.
[Bryce] Mireya, do you copy?
[radio static]
[bleep]
[radio static]
Mireya, do you copy?
[radio static]
Bryce for Russ. Do you copy?
[radio static]
[Jordan] Bryce, even the thermals can't see anything.
[bleep]
[Bryce] With so much snow and fog in the air,
the surveillance ray can't pick up on anything.
And I don't think this storm
is going to break any time soon.
But I do know that the A.I.
detected multiple upright walking targets
on that mountain with Russ and Mireya.
So I can either sit here blind
or I can head towards them
in the hopes that my comms will eventually work.
Either way, I'll be closer to Russ and Mireya
and can help join in on the search.
All right, You guys keep watching this.
[narrator] Back on the south-west side of the mountain,
Russell continues to try and intercept
the heat signature that Bryce spotted on the array.
Did you see this?
Look at that.
[bleep]
We have a footprint.
Holy crap.
We have a track.
This is fresh.
Let's keep going. I'll circle back and cast this thing.
[bleep]
Let's get back. Back up.
Holy crap.
One.
Two.
Three impressions.
Look at that, but they're not very big.
I think we got a juvenile.
Russ for Bryce.
[radio static]
I'm unable to reach Bryce.
I don't like not having comms.
The weather's picking up.
It's coming down a lot faster.
The more moisture,
the more water gets in here,
the more deterioration I get.
Look at this.
There's pooling right in here, the water.
I need to get the casting material in there,
like, right now.
I think we've got some really good evidence here.
Normally, I wouldn't cast in these conditions.
But I've never seen a print this size.
This could be a juvenile print.
If I can capture this evidence, this could prove
that they're raising their young here.
After I cast these, I'll go back and do the other one.
I've never seen anything like this.
I think this is the left and right footprint.
I think we've got two here,
a juvenile and an adult.
This is a huge find.
I can't believe this.
I don't know if there's enough
to get a full print on this,
but I wanna get these toes.
These are so much smaller.
How do we get eyes on these things tonight?
[Mireya] Let's see if we find some tracks right here.
The heat signature I'm after is in this direction,
I'm trying to find any signs of movement, tracks,
anything that could have come through here.
It actually looks like something
has been moving through here.
Right in here.
Look at the way these are bent down.
It just looks like this has been
matted down in this direction.
I say we keep going that way
and keep following this.
[twig snapping]
Shh. Listen.
[rustling]
I heard something over there.
It is so quiet down here.
[narrator] As temperatures continue to drop,
the rain has turned to snow,
while Bryce has now made his way
across the valley in search
of the heat signature he spotted earlier.
We are in the thick of it right now,
and I'm getting just a real
uneasy feeling being here,
and I feel that head to toe.
That's weird.
Infrasound is something that we've
explored with these creatures
that could be the cause
of these uneasy feelings.
[narrator] Infrasound is sound
below the range of human hearing,
which is generally accepted as below 20 Hertz,
it can be generated by natural phenomena
like earthquakes and volcanic eruptions,
as well as by animals
such as whales, tigers and elephants.
Some humans can be adversely affected by it.
Bigfoot researchers suggest that
Bigfoot can not only communicate using infrasound,
but can use the sound waves
to disorient other animals.
[twig snapping]
[Bryce] I'm hearing stuff pop above me.
Holy [bleep]. Holy [bleep].
Hold on. What the [bleep] is that?
Whoa!
I don't know, but from here it looks like it was
put in the ground upside down.
This just is creeping me out big time.
I was just seeing if there's any tracks,
I mean, look at this fresh snow.
I just came in right through here.
And there's nothing else around.
Yeah, This is buried
I mean, you can see this was
jammed in here with such force.
This is just branded in there.
This is buried upside down
in the ground.
And we really haven't seen that,
except for places like Alaska.
[Mireya] There it is.
Oh, my God.
[man] That's weird.
[Mireya] That is weird.
This may be another boundary marker,
but honestly, it's a little different
from what we've seen in the past.
Uh, you know, the structures that we've been
discovering that we feel have been marking
out boundaries have been more
apex structures with ornamentation.
What the hell is this thing doing here
in Northern California?
It has me thinking and wondering.
Could this possibly be
the same group of Bigfoot from Alaska?
[Mireya] I'm not seeing anything here.
[narrator] After losing communication with the rest
of the team for over two hours
and as the snow continues to fall,
a half mile from Bryce,
Mireya proceeds to search in the direction
the heat signatures were last known to be heading.
[Mireya sighs] Crazy.
The weather
has changed so dramatically,
even just in the time that I've been
out here searching,
that now we've got a buildup of snow,
which, up to this point,
the weather has been really hurting
and challenging us, like we're down comms.
Visibility isn't good,
but this might actually help us
In looking for tracks.
Oh, [bleep].
No way.
Oh, God, look at this.
There's two nests.
Oh, God, look at this.
There's two nests.
You look at this
and there's absolutely no confusing this
for anything else other than a nest.
Deer couldn't do this. Bear couldn't do this.
If I'm honest, what it reminds me of
is very much like a nest a gorilla would make.
The thing that strikes me
is that this was just constructed.
Look how fresh those pine needles are.
I mean, they're bright, bright green.
I don't want to touch anything
because I want to be able
to collect evidence from this.
But look at this, the way that all this
is sort of woven on the bottom
to create this geometrical shape
and then all of this bedding
right in the middle, I mean,
the nests that we found in Northern California in the past,
they didn't look recent.
[Bryce] Check this out. Look at all these breaks.
Look at this. Right here.
What the [bleep].
This is crazy.
And the thing about primates, like gorillas,
when they make a nest,
it's to sleep in that night and only that night, which means...
we're in something's territory.
And having two nests this close to each other,
we could be looking at a family group.
But given the size of the nest,
we're looking at huge animals.
What I want to find is what made these.
Oh, my God!
Look at this.
There's another one.
And it's also big.
This is insane.
Wow.
If what we were picking up on that thermal made this,
that means that we're really close,
and this is the closest we've ever been.
Look at this.
[bleep]
There's something that...
took all the branches from here
to bring up there where we found the nest.
-[radio beeps] -Mireya for Bryce or Russell.
Bryce or Russell, come in.
[radio static]
Mireya for Bryce.
But let's keep going
and see if we see anything down there.
[Russell] It's almost full-on daylight.
We have to make contact with the team.
We need to rendezvous.
[narrator] With the first wave of the storm having passed,
rising temperatures and rain have melted the snow
and cleared the ground.
However, the next wave of the storm
is expected to make landfall within six hours.
Meteorologists have predicted lightning
and up to four inches of rain,
which is enough to cause flash floods and landslides.
Russ for Mireya or Bryce. Either one of you copy.
Hey, Russ, I read you.
What's going on?
I got an idea. We've been running all night long.
This is a pretty hard push.
How about if we meet up in about two hours?
If I give you some coordinates,
can you guys both meet me at the bottom of this creek?
Absolutely, man, that's a good plan.
I had the craziest night, man. You would not believe it.
[Russell] Have you heard anything from Mireya yet?
Negative. I have not heard from Mireya.
Hey, guys, I'm back on comms now,
and I heard everything you said.
I never reached whatever that thermal target was,
but, man, do I have something to show you.
You got it, Mireya. Good to have you back on comms.
-I'm on the way. -[radio beeps]
Got to get those casts pulled
and meet the team in two hours.
Here we go.
Wow. Look at that.
I don't think I lost any of the detail in here.
All right, let's head over to the other location.
I'm kind of excited to see those others.
Wow.
Look at this. I have a left foot.
And right up here, I have the right foot.
We have a perfect set of tracks, left and right.
This is like the lottery of footprints right here.
My hunch is telling me
that we're looking at a juvenile.
Different size prints proves more than one creature.
That means that we could have identified a family group,
and we've zeroed in on their breeding grounds.
I want nothing more than to sit here and clean this thing out
detail by detail,
but I gotta meet up with the team.
I gotta show them these tracks.
[grunts]
Phew!
That's some terrain, huh?
-Man, that's crazy. -[Mireya] And what a night.
-[Russell] Yeah. -[Mireya] That weather was just so crazy.
[Bryce] Yeah, absolutely.
[Russell] Check this out.
Let me show you what I got.
This is the first one I found. Look how wide this thing is.
-[Bryce] Oh, my God. -[Mireya] Oh, wow, that is wide.
[Bryce] Oh, wow!
[Russell] Look how flat and wide that thing is.
Look at the size of this thing.
[Bryce] Oh, yeah.
[Mireya] I mean, this is really interesting.
You can see how there is what looks to be the toes splaying.
And we wear shoes, so you don't often see this
because our toes are always constricted.
I'm looking at these prints,
and I'm observing interesting physiological traits,
like the way that the toes are splayed out,
which is interesting because that tells you
a lot about locomotion.
In environments just like this,
where I worked with natives who never wear shoes,
you can see the toe splay.
In fact, you see a thickening of their sole.
The feet are a reflection of the environment...
and this is something that's walking upright.
Wow. This is a great find, Russ.
Thank you.
Wait till you see these other two.
Bryce, I got a left and a right.
-[Bryce] No way. -[Russell] Look.
[Bryce] Oh, my God, they're a set.
-[Russell] Left and right. -[Mireya] Wow!
Oh, wow. Russell. That's outstanding.
[Russell] What makes this unique
is having a side by side print like that,
you have the left foot and the right foot,
which is like the Holy Grail
of collecting these footprints.
Well done, man. That's incredible.
[Russell] This is about two-thirds the length of this one.
-Judging by the size. -[Bryce] I feel like this is the biggest one, right?
[Russell] That's huge.
In primates, there's a lot of cases of sexual dimorphism
where the male is bigger than the female.
Sexual dimorphism is a term used in science
to describe size differences
between a male and a female in a species.
We don't see this in all animals,
but we do see it a lot in primates like gorillas
where the silverback male
is going to be significantly larger than a female.
So we could be looking at a juvenile print
or we could be looking at a female print.
Gorillas, in particular, male gorillas,
are 30% larger than female gorillas.
-[Bryce] Man. -I think this might have been a juvenile...
-Yeah. -...and an adult.
Told it to start up, circle back and go down.
[Bryce] You know, it's so funny that you mentioned juvenile
because last night,
you know, I was tracking this third anomalous target
which led me into this zone,
and, Russ, I found an upside down tree stuck into the ground.
It wasn't a tree, it was smaller,
but it was in there like three and a half feet.
-Like Alaska upside down tree? -[Bryce] Yes, much smaller
and just more ominous because when I was in there,
I just felt like I was in the lion's den, man.
-[Russell] Wow. -I felt like I was being lured in there.
So, yeah, you may have a male and female or male juvenile.
But obviously, there's multiple creatures from these tracks.
-You know you've got two different individuals. -[Bryce] For sure.
[Mireya] The most important thing is
it could be that what we're looking at here is a family group.
Russell, this is a really, really great find.
But you guys, I want to take you to where I was last night.
You are not gonna believe what I found.
-Oh, yeah? -Yeah.
-I'm intrigued. -What'd you get?
I don't want to tell you. I want to show you.
-Pack this up and let's go. -[Russell] Oh.
-I'll take you there. -[Russell] All right.
[Russell] Oh, crap. Look at that.
-[Bryce] Oh! -[Russell] Oh, my gosh!
Isn't this crazy? Look.
Three nests.
[Bryce] Oh, wow!
It doesn't look like anything's changed from last night,
so whatever made these didn't come back.
[Bryce] Wow.
I'm just flummoxed. This is wild.
These are absolutely just gigantic.
These nests are intertwined together,
and they have green fresh boughs on top of them
to make them comfortable,
like you would sleep at any hotel.
I was not expecting this.
[Bryce] Where's the third one?
Follow this way.
Hey, Russ, up here.
-[Russell] Oh, wow. -Oh, my God!
That is huge.
[Russell] It's like woven together.
This is what we ran into right here in California
when we found two nests.
But now we're looking at three,
which would indicate
we're looking at three different creatures
on this mountain.
Tell me this wouldn't be the alpha position.
To me, this spells out like some kind of family group
where you've got an alpha watching out for the other group members.
-And if we have a little one in a group... -[Russell] Right.
...it's usually going to nest with the mother.
That makes total sense.
This one particular site, there actually was a cluster of nests.
Wow.
My kind of gut reaction to this situation
was that it was a birthing site.
The reason I think that is there was one nest
that was in the crook of a bush
about two and a half feet off the ground.
When I saw it, the first thing that came to mind was,
"My gosh, this is a bassinet."
[Bryce] When I look at the size of this thing,
I could fit two of me inside of this.
And just the way these nests were situated together
leads me to believe that
this was more than likely a family of Bigfoot.
-Wow. -Okay. Right here? Right at the edge?
[Mireya] Nine feet.
So for reference, I'm going to label this one just Alpha Nest...
-[Russell] All right. -...and write down the measurements,
and we'll just go to all of them,
-get all that first... -[Bryce] Yeah.
-...and then we just start diving in. -[Bryce] Great.
-[Mireya] All right, let's measure this one. -[Russell] Yep.
We're at nine feet on this one.
-Same. -Oh, wow.
-Same. -[Mireya] Here.
Yep. I got it.
Right at eight feet.
[Bryce] These other two nests
are measuring to be about the same size as the first one,
which means there are at least three creatures here.
And if this is a family grouping
with the mother sharing the nest,
then we could be looking at possibly four Bigfoot.
Seven and a half feet.
-[Mireya] Yeah. -Good.
[Bryce] Man, I'm almost seeing, like, an impression in here, too.
Are you guys catching that?
If you really look at the composition of it,
you'd have to imagine that something had to have been inside
in order to get this done and matted down in this way.
[Bryce] Yeah, right.
[Mireya] Which is great for us
because we may be able to find some DNA in there.
Yeah. Speaking of, what's the best way to pull some of this DNA?
[thunder crashing]
[Mireya] Let's split up because there's three of them
and the weather is really coming in.
Yeah, it is.
First thing I want to do is use the technology that we have
that will help to identify
our best chances of getting a DNA signature here.
So if you guys want to start working on the outside,
-by looking for any hair... -Yeah.
-...anything that looks unusual that we can collect... -Yep.
-...and then we can really dive in. -[Bryce and Russell] Great.
[thunder cracking]
[narrator] With the next band of the storm
expected to hit land in less than an hour,
Mireya must gather any evidence now,
before it washes away,
using a hyper spectral camera
that's equipped with technology
that processes data
across the entire electromagnetic spectrum,
allowing it to detect traces of animal DNA.
It's detected something right here,
so I'm gonna go ahead and set that.
That way we can keep that data,
and I'm going to collect exactly from that spot.
It's going to give us our best chances
of getting any kind of DNA signature.
I'm trying to collect as much evidence as we can while we still have it,
because I don't know what's going to be left when this next storm hits.
[Bryce] Good grief, Mireya.
Now that I'm in here, look at the size of this thing. Look.
[Russell] You look like you're in a six-person hot tub.
I mean, this thing could accommodate several huge humans.
[Russell] Agreed.
That's a lot of space.
[thunder crashing]
[man on radio] We're gonna have to shut it down.
[Russell] Copy that. We'll finish up here and head back.
[man] Negative. We need everyone to pull back position, Russ, now.
-Hey, Bryce. -[Bryce] Yeah?
We gotta get out of here.
-[Bryce] I'm on my way. -[Russell] You done?
[Bryce] Yeah.
[thunder crashing]
[Mireya] The thing that made me want to start doing field research
was a magazine article
that I read about the most endangered primates in the world.
And it wasn't the ones with the beautiful photographs that captured my attention.
It was actually the line drawings.
Because here they were on the verge of extinction,
and they had never even been photographed.
That really captured my attention.
I knew then and there that that was what
I was going to dedicate the rest of my life to.
And for now, more than two decades,
I have been in search
of rare and elusive primates on the verge of extinction
that have not even ever been documented.
[Russell] After the storm came through,
it made all of the roads and trails impassable.
But we're not giving up.
Nothing here on prints or anything. Anything that--
[Mireya] No, just some turned up ferns.
[Bryce] Nature still has so many more surprises for us, I think.
[Mireya] I remember so many times
during my previous expeditions
where I was out searching for a rare elusive animal
that I'd been told over and over I'd never find.
There were so many moments
where I could have just given up
because it seemed like a failure,
walking ten hours a day for months on end and not seeing something.
But then you have that breakthrough moment,
and that can only come
from patience and perseverance.
[narrator] After weeks of searching
for the suspected family of Bigfoot,
the team gathers to speak to an expert of forensic podiatry
about the three detailed prints
they collected near the nest site.
Dr. Emily, thank you so much for taking the time to speak with us today.
Thank you so much.
First of all, can you tell us a little bit about your work?
So I am a functional podiatrist
and a human movement specialist,
and I have a big interest
in the evolution of bipedal-ism.
Well, I know we sent you tracks
that we found out in the field.
Can you break down your process
of how you analyze a foot track?
What I did is I set them down all on the floor,
and then I looked at them from a distance
to see what kind of jumped out at me
from the shape, from the size,
from the detailing of the prints.
And then I went in deeper
and started taking actual measurements
of the size of the foot, the breadth of the foot.
This is based off of forensic podiatry,
which is a division of podiatry
that uses footprints that would be found at a crime scene
to then try to determine
height, weight, et cetera, even gait pattern, of a suspect.
[Bryce] I got to ask you, Dr. Em,
this is probably the first time
anybody has come to you
with what might be a Bigfoot foot to analyze.
Did you see anything
that, you know, jumped out at you
as being different or strange?
Yeah, absolutely.
Thank you for sending them to me.
And what I want to share with you
is first with the smaller pair.
Just because those were so well-articulated,
even the web space
and in between the ball of the foot
and where the digits start to make an imprint
was so well defined.
I thought that they would look more primate
and they actually looked more Homo sapiens.
Well, that's interesting.
[Emily] Now, not evolved Homo sapiens.
What I'm looking, just based off of the assessment,
would be human-like.
[Mireya] In looking at our ancestral lineage,
we see in primates that they have
what sort of looks like they still have a finger,
whereas in humans, we have a big toe.
What is it that you're seeing in those prints?
Yeah, so that is actually one of the biggest distinctions of what I saw
is this well-defined big toe joint, you could say.
But what really stands out around the prints
that makes them less human-like is the breadth.
So the width of the metatarsal area, so here,
this is going to be wider than in Homo sapiens foot,
and then down to the calcaneus.
It's interesting to hear that Dr. Emily feels
that this cast is similar to a human foot,
but there are key differences.
Because if this print didn't come from a human,
then these differences might provide real insight
into how an animal would interact in this environment.
Are you able to determine the ability of these things
to be able to travel long distances?
[Emily] Based off of it being a human-like foot
means that it would be upright,
which inherently gives the ability to walk longer distances.
Mm, okay.
They have a wider foot that allows for
maybe more stability on forest floors,
rocks and branches, and things like that.
[Bryce] Got it.
So what's your takeaway from these tracks?
[Emily] So when I did the measurements,
there are well-accepted calculations
to find averages between foot length and height.
What they found is that there's a 15% correlation.
So I measured from the center of the heel
to the middle of the big toe
to determine the foot length.
Take that and then use that 15% calculation
to determine potential height from this print.
We're dying to know what you get.
[Emily] So from the smaller print,
the height is around 6'9" to 7'0".
-Oh, wow! -Wow.
On the smaller pair.
-[Russell] Wow. -That's crazy.
So what are the calculations
on the height for the big print?
So the large print, which was 42 centimeters,
is an estimate of 9'0".
Wow.
So what we're dealing with then
would be something that is nine-foot tall
and then another one that's six to seven-foot tall
walking around the forest upright,
-barefoot. -Barefoot.
Wow. I'm amazed.
Hearing a seven-foot tall and nine-foot tall creature
walking around just a stone's throw away from the nest that we found,
that's validation enough for me
that families of Bigfoot exist,
and they are here.
When it comes to the smaller feet,
is it possible that this could belong to a juvenile?
If we think of size as being an indicator,
then sure.
With the more well-defined smaller prints,
the fact that they're very well defined
makes me think that there is
more of an effortlessness in the movement.
When we are younger, we move more fascially, there's a lightness.
Think of like a toddler that will never get tired.
And that's something that could suggest
that it was a younger animal that made that imprint.
Hmm. Fascinating.
If Dr. Emily's assessment is correct,
then we now have tangible evidence
of a juvenile Sasquatch.
[Emily] I hope that my insight was helpful to your work.
[Mireya and Russell] Very much so.
-[Mireya] Thank you. -[Bryce] Absolutely.
[Bryce] Coming back to Northern California,
we were hoping to prove that this was a breeding ground.
We discovered a ton of evidence.
[Mireya] God, look at this.
There's two nests!
We've located a cluster of woven nests.
-Bryce. -[Bryce] What is that?
[Russell] Massive tree structures.
Wow.
[Russell] More footprints...
Left and right.
[Mireya] Multiple samples of DNA.
[Russell] We found blood samples and video evidence.
Look at this.
You see that?
[Mireya] Discovery is a process,
built one finding at a time.
It's a lot like putting together a puzzle.
You're finding isolated pieces.
Wow.
[distant disembodied growl]
[Mireya] When you start putting them together,
you really start to get that clear big picture.
[Bryce] With each expedition, we've gotten closer,
unveiling a greater pattern.
And the more evidence that we keep gathering,
just tells me that it's only a matter of time...
before we've solved this once and for all.
