[narrator] Previously on Expedition Bigfoot...
I have a tracker that moved.
I think it went in the water.
Whoa.
Russ and Mireya are gonna go across the mainland
to follow this tracker.
I don't think my work is done here.
I think there are more Bigfoot
here on this island.
Oh [bleep] we might be looking at a kill site.
[Russell] Oh, here were go. Oh, wait.
[tracker beeping]
[Russell] It picked up something right over this way.
This is our beginning point
and the best lead we've gotten so far.
[Mireya] It's moving.
[Russell] Holy crap.
That looks like something standing up.
We're talking two at the same time.
You think these creatures have the ability
-to affect our mind or-- -Yeah.
[man] What is going on?
They're capable of just about anything.
Something moving over there.
[Russell] Is that a bear, maybe?
[Mireya] Check this out.
[Russell] Look at that.
[Mireya] I think we found a handprint.
[Russell] Holy [bleep]
[theme music playing]
[Ronny] So excited, guys.
They're over here.
[Mireya] Just be careful where you step,
-stay on this side. -[Ronny] Okay.
[narrator] After the discovery of what appears to be
a massive handprint,
Ronny decided to leave Prince of Wales Island
and join Russell and Mireya
at the location of the prints.
-[Mireya] Take a look at this. -[Ronny] Oh, wow.
-[Mireya] Up here. -[Ronny] Oh, yeah.
-The hand... Oh, my God. -[Mireya] You see that?
[Ronny] Those fingers look long as hell, dude.
Whoa!
[Mireya] And then, there's something else over here.
We think these look like knuckle prints.
[Ronny] I can see the indentation right there.
This could be an incredible find.
There's reports of them not only on two legs,
but they'll get down on all fours
to actually move quicker through areas.
[Mireya] Remember that skull recreation
that we analyzed last year?
Here it is, you guys.
[Ronny] Yay.
[narrator] During last year's expedition,
the team had a forensic scientist
recreate a possible Bigfoot skull
based on eyewitness testimony.
[Mireya] What I thought was really interesting is
this opening at the base of the skull.
[narrator] Mireya observed that the skull appeared
to have hybrid characteristics
similar to both humans and apes.
It would be able to walk bipedally,
but it would also spend time on all fours
walking quadrupedally on the ground.
It's so strange to find something like that here
because we've been seeing a lot of indentations
throughout the forest, but nothing definitive.
But to me, even more interesting,
that because that...
The hand, and then the knuckle,
that is such ape-like behavior.
The knuckle walking.
It's almost like he's...
They're pulling themselves up over this thing.
And you guys found footprints as well?
[Ronny] Yeah.
This is something that actually has me intrigued.
You see this print, this footprint right here.
[Ronny] Yeah.
[Russell] And then, right here,
this is a right handprint, right?
So, the footprint... Right handprint,
this thing, direction going straight out that way.
Guys, we have two sets of tracks.
-[Mireya] Yeah. -[Russell] Yeah.
-Two. -I mean, not just one, two,
and a freaking handprint, which is insane.
So, you guys were able to scan this
-and sent it to Bryce? -[Mireya] Absolutely.
He'll be able to get dimension, ratio on that,
but I really want to see what made these.
So, I just got an email from the team.
-Let's take a look. -[phone rings]
[Mireya] Hey, Bryce. Did you get the scans?
[Bryce] I'm looking at them right now.
Holy [bleep] is that a hand?
-[Mireya] Yeah. -[Bryce] Oh, yeah.
Look at that.
[Ronny] It was at least twice the size of my hand.
Maybe bigger.
Oh, my God.
Wait.
Is this two different handprints?
There were two sets of these,
so there seemed to be two of them.
[Bryce] Oh, wow.
If we're talking about multiple individuals,
then this is pretty incredible.
[Bryce] Okay. So, what's next?
Do you have a trajectory? Where are they headed?
This area is so vast, so dense,
and this terrain is so difficult
to get across that...
I mean, it's gonna take a lot for us
to pick back up on this track.
The good news is,
we believe they're headed east along this river
and according to the maps,
the river valley forms a bowl with steep cliffs
on each side.
Perhaps we can trap these creatures in that valley.
Now, we just need something to scan the area quickly.
You know what?
I might have the perfect piece of tech for this.
It's used in search and rescue
for locating missing people.
Let's bring everything and the kitchen sink this time.
[Bryce] You got it.
Why don't you send me the coordinates
of where you found those handprints?
I'm gonna make a call
and we're gonna make this happen.
-Thanks, Bryce. -Get ready, Bryce.
[Bryce] Perfect. All right. I'm on it.
[Mireya] All right, guys.
Well, we wanna get to that area.
All right.
[Mireya] We don't have much time.
My guess is if whatever we're tracking
makes it out of that river valley, it's gone.
-All right. -All right. Let's go.
[tense music playing]
[Ronny] Where we found that handprint and those footprints
are right before this river breaks into this fork.
So, I'm staying to the right,
Russ and Mireya are gonna handle the other side.
[narrator] The 20,000-acre river valley
is surrounded by 3,000-foot mountains on all sides.
The team has split up to cover as much
of this massive swath of land as possible.
They're hoping Bryce's tech
will give them a leg up in their search.
This is our best lead
and we are not stopping until there's no hope.
And right now, there's hope.
[tense music playing]
[Bryce] The drone team should be arriving at the location
right about now.
I'm heading out to coordinate with them.
Given the rough and dense terrain
that surrounds this area
and the head start that this creature already has,
I knew we needed a technological advantage.
Time is running out,
it's time to bust out the big guns.
Hey, Jon.
Hey, Bryce.
What we have here is the Autel Dragonfish.
Primarily, we're doing overwatch,
search and rescue, any type of apprehension.
[Bryce] This fixed-wing drone is equipped
with three different types of cameras.
A wide angle lens, giving us a complete overview
of the search area.
A 20x optical zoom lens,
which can determine the color of someone's hair
from 800 feet in the air.
And lastly, a thermal camera,
which picks up any kind of heat signature.
There's no way anything is escaping us now.
Well, let's get this thing in the air.
[Jon] You got it.
[drone whirring]
[Jon speaking]
[safety officer speaking]
[Jon speaking]
The most important part
of what makes this drone so special
is its ability to stay in the air
and survey longer than any other drone.
300 feet, approaching 400,
she's gonna make a slight left turn.
[Bryce] During forward flight,
the fixed-wing creates lift and conserves battery power.
This can add an extra two hours per flight,
versus conventional drones
and could prove key
when searching such a vast and dense target zone.
[dramatic music playing]
[Jon speaking]
[Bryce speaking]
So, this thing flies in continuous circles,
-is that right? -[Jon] It is.
[narrator] In order to maximize flight time,
this fixed-wing drone does not hover in place
like a traditional multi-rotor drone.
Instead, it tracks its targets
by flying in a circular pattern overhead.
This device not only gives us eyes from the sky,
but it allows us to search large areas
with pinpoint accuracy.
No other drone has afforded us these capabilities before.
This is the most sophisticated
piece of technology
we've ever used on our hunt for Bigfoot.
[Mireya] Mireya for Bryce.
[Bryce] Mireya, I read you loud and clear.
I'm at the river where it splits off into two.
You guys aren't gonna believe this,
but I got us a fixed-wing drone.
And it can stay in the air for hours on end.
If something's out here, this thing is gonna find it.
[Mireya] Amazing. We'll keep heading up river.
[Bryce] Great. Talk soon.
[narrator] Bryce and the drone team
have positioned themselves at the west end of the valley
where the rivers converge.
From here, they'll monitor the drone feed
as Ronny, Russell, and Mireya continue their search
near the banks of the two rivers.
I'll turn on dynamic tracking,
go to this area.
[narrator] The drone team will remain until nightfall
when their ability to navigate the drone
safely diminishes.
[Bryce] Wow.
[Jon] We got camera here.
[Bryce] Oh, that's incredible.
Wow.
[Jon] There's our wide camera, our zoom camera,
and then we can jump into our infrared.
[Bryce] Wow.
-Can we track down our team? -[Jon] Absolutely. So...
[Jon speaking]
I can see a heat signature right there.
Oh, wow, is that them right there?
[Jon] It is.
Right there.
[Mireya] Hey, Bryce.
[Bryce] Yeah, we see you.
Can you wave?
Mireya, we're gonna track down Ronny now
-on the other river. -[Mireya] All right.
We're gonna keep heading upriver then.
[Bryce] Sounds good.
[dramatic music playing]
Bryce for Ronny.
Hey, go for Ronny.
[Bryce] Hey, Ronny, we got the drone flying overhead.
We're gonna lock into your position now.
[Ronny] Copy that.
[Jon] That's him right there.
[Bryce] That's incredible.
Target identified and locked successfully.
[Ronny] I don't have visual. Where are you?
[Bryce] We're about 800 feet above you.
You can't see us, but we can see you.
[Ronny] That is epic.
[Bryce] Well, if you can't see us,
that means Bigfoot can't see us either.
[Ronny] Exactly. I love it.
[Bryce] That's amazing.
We're gonna send the drone up the river to scout ahead.
All right. Copy that.
The drone's gonna be able to give us
a bigger bird's-eye view.
So, that way, we'll know exactly where to go.
So, what do you think it was?
The size of that hand?
I can't think of anybody that has hands that big.
[Mireya] It's one of the things
that's really intriguing about our find.
Yeah.
[Mireya] Is that generally, we find a footprint.
-Right. -[Mireya] But the fact
that this was coupled with a handprint
and it didn't look like a bear paw or anything else.
[Russell] Yeah, that's pretty puzzling, actually.
[drone buzzing]
[Bryce] Whatever it is has a head start on us.
Can we check further upstream?
[drone buzzing]
Got something right there, huh?
I do.
[Bryce] What is that right there?
[Jon] Something definitely moving around in there.
What is that?
Can we zoom in on that?
I'm gonna take a look a little bit closer
with thermal here.
[Bryce] Oh, it's moving. It's moving.
-[Jon] There it goes. -[Bryce] Oh, wow.
What is that?
[dramatic music playing]
Oh, wow.
Whatever it is, it's moving pretty fast.
[Jon speaking]
[Bryce] It's gone now [bleep]
Can you go to the regular lens?
-Nothing. -[Jon speaking]
Mireya, Russ, this is Bryce. You guys copy?
[Mireya] What do you got, Bryce?
Hey, we're catching something
here on the drone in the thermal.
It looks humanoid in shape.
[Bryce speaking]
Are you serious?
It looks like it's about a few miles up
from where you guys are right now.
Oh, it's moving right now.
If it has that far of a lead on us,
it may take us a while to catch up.
Do you have any idea where it was headed
or where the river leads to?
[Bryce] Stand by. Let me find out right now.
Hey, Jon, can we tell where this river goes?
[Jon] Yeah. Go ahead and take a look.
It's quite a ways up there.
As you can see, they're winding up here
towards this icy area.
[Bryce] Is that a glacier?
It is.
[Bryce] Oh, wow.
Hey, Mireya, it looks like this river
is leading up in elevation straight into a glacier.
You guys need to head there fast.
All right. We'll keep going. Thanks for that, Bryce.
[Bryce] You got it.
[narrator] While Mireya an Russell make their way
toward the glacier,
where they believe the creature spotted
in the thermal was heading,
Ronny is continuing to make his way up the other river.
It sounds large.
Hey, Bryce.
Go for Bryce.
I have something, just in the tree line.
I can hear it, it sounds large,
but I have no visual on it.
[Bryce] Really?
Hey, can we go over to Ronny's position?
[Jon] Yes, we can.
Drone's on its way to you.
[Ronny] Okay, that would be great, man.
I mean, it's right over there.
I can hear branches popping.
But I can't see anything. It's so thick.
Okay. We should be tracking Ronny here in just a second.
[Bryce] Yeah, I got him right there.
[Jon] Yup.
[Bryce] Hey, Ronny, this is Bryce.
We got a visual confirmation of you right now.
[Ronny] Bryce, this tree line is really thick,
but I hear something big in there.
It's somewhere right around in here.
Oh, look, right there. I got something right there.
[Bryce] Oh, wow.
Yeah, check it out. Look.
Something's just standing there.
Hey, Ronny, I'm picking something...
-Oh, my God, it's moving. -[Jon] Oh, there it is.
[Bryce] This one is moving, too.
Ronny, I got something moving about 200 yards up
from where you are right now.
[Ronny] Holy [bleep] I can hear it,
but I can't see it.
Whatever it is, it's moving back into the trees.
I'm losing visual.
But we're making another turn around those trees.
Stand by. Hold on.
We lost it.
[Ronny speaking]
Ronny, you're actually not too far from my position.
I'm coming towards you right now.
[Ronny] That'd be great.
Because whatever this is, it sounds really big, dude.
[Bryce] Ronny, don't approach it alone.
Wait for me.
[Ronny] Copy that.
I'm on my way.
[narrator] Bryce will make the mile-and-a-half trek up river
to help search the clearing
where a humanoid thermal signature
was just spotted 200 yards from Ronny's position.
I'm about a quarter mile out, closing in fast.
Bryce, I'm not hearing anything anymore.
And I don't wanna lose it.
I'm gonna move in from my position.
Got it. I have your coordinates.
I'll meet you out there.
We're gonna start making our way up
and Bryce can meet up with us.
He has our position.
[dramatic music playing]
[Ronny] Man.
It's just so much ground to cover.
And I know there's something out ahead of us,
so we gotta be very careful here.
Look at this.
Wow, this is broken off.
There's a deep impression right here.
Almost like something stepped right down,
left a deep impression right here.
It's a footprint right there.
From here, where that stem is broken to this,
that's a six-foot stride at least right there.
Heading right up.
Just trying to scan the area here,
so these trees just stack up on top of each other.
Anything over 71 degrees is gonna pop like crazy.
Oh, what the hell's this?
Got up the trail here, it looks like.
Is that Bryce?
Hey, Bryce, come in.
[Bryce] Yeah, I'm here.
[Ronny] I can see you coming up on the thermal.
[Bryce] Copy.
Hey, did you see anything come through here?
[Ronny] I found what looked like some footprints.
They were heading up there.
I say we keep on moving
because it looks like they're fresh.
-[Bryce] Let's do it. -[Ronny] All right.
[eerie music playing]
[Ronny] Let's see.
Okay.
Looks like it's starting to clear up over here.
[Bryce] Yeah.
Look at this.
-[Ronny] Oh, wow [indistinct] -[Bryce] Look at this.
[Ronny] [bleep] they're coming in and out through this.
[Bryce] Oh, wow.
-[Ronny] All clear. -[Bryce] Yeah.
[Ronny] Snow right there.
Should we check it for tracks?
[Ronny] Let's do it, yeah.
I mean, the great thing about having snow around here
is if something steps through,
it's gonna leave a pretty good track, right?
[Bryce] Absolutely.
Nothing.
Can you smell that?
Oh [bleep] Ronny.
What the [bleep] is this?
Fresh kill.
[Ronny] Holy [bleep]
[tense music playing]
[Bryce] What the hell is this?
[Ronny] [bleep]
Dude, this is fresh, man.
[Bryce] I'd say so.
When we get to this clearing,
we're hit with this overwhelming smell,
and then that's when we realize
there's actually a fresh kill right in front of us.
The entire area is soaked in blood.
Whoa.
[Bryce] Is that a rib?
[Ronny] Two ribs. Two ribs.
I would have to think
with the size of this rib bone,
that this is like an elk
or the black-tailed deer that's...
The Sitka Blacktail?
[Bryce] Yeah. Man, this stinks.
[dramatic music playing]
[Ronny] Hey, what we got, I think...
-[Bryce] You got something? -[Ronny] I think so.
I mean, it looks like that was just broken in half.
[Bryce] Yeah, you're right. Check that out.
This has been broken through.
[Ronny] On that side, too?
[Bryce] Yeah. That's a big bone to break.
That was either bitten through or broken through.
The biggest takeaway from this bloody mess
could be that Ronny found a rather large bone
which could unlock a critical clue.
Holy crap.
Mireya once told me that early humans
used to split bones and drink the bone marrow,
which may have been important in the development
of prehistoric hominid brains.
[narrator] Recently, scientists have hypothesized
that human ancestors
wouldn't just eat the meat of an animal,
but consume marrow encased within the bones.
The protein and fat-rich substance
may have acted as a catalyst
in the development of humans'
distinctively large and complex brain.
Thus, spurting a major step in human evolution.
Looking at this bloody massacre,
it doesn't look like normal animal predation.
What the hell?
[Bryce] That could be because we're dealing with something
that's not a normal animal.
It's a human relative
and it may explain the obsidian
Russell found as well.
Holy [bleep] that's not glass, that's obsidian.
[narrator] Last week, while investigating a believed
underground Bigfoot shelter,
Russell discovered shards of obsidian
also known as volcanic glass.
Soon after, Bryce discovered
that obsidian was also found in a nearby cave
along with the 10,000-year-old remains of a human ancestor.
Suggesting that he was using it as a cutting tool.
Bigfoot may just be a type of early primitive human species.
I mean, my gut's telling me this isn't...
this isn't done by a bear or a big cat,
-or even wolves, man. -[Ronny] No.
I've come across remains of animals in the forest before,
but nothing like this.
And the fact that this is right in the same area
where Bryce got this thermal image on the drone,
I'm confident this is Bigfoot.
Hey, Mireya, Russ, you guys copy?
[Mireya] We got you, Bryce.
Hey, Bryce.
Hey, we just wanted to let you know
about a discovery we made.
Ronny and I were tracking
a real promising heat signature.
We didn't find what made it,
but we did find something else.
What'd you find?
[Bryce] It's terrifying.
It looks like a murder scene.
Bones, blood splatter.
Hey, guys, let me tell you, be on the lookout.
There's so many scavengers around here.
Nothing is gonna sit on the forest floor
for any amount of time,
so that's definitely a fresh kill.
Is there any evidence of what may have killed it
that was left behind, like footprints?
[Bryce] Well, the bones have been split
and drained of the bone marrow.
[Mireya] Did you bag those?
We did. We got them in secure.
[Mireya] Okay, good. Well, listen,
we're still chasing whatever it is you saw, Bryce.
And all signs are pointing to it
heading directly towards the glacier at the top of the river.
So, we're gonna keep chasing it as long as we can.
[Bryce] Copy that.
We're gonna look around here a little bit longer for any more evidence.
So, just stay in contact on these comms.
All right. Keep us posted.
Yeah. Be careful, guys.
[Ronny] You know what?
Where's the rest of the body?
[Bryce] What do you mean?
[Ronny] This is like a pack of wolves, right?
[Bryce] Yeah.
You would see drag marks.
[Bryce] You would see tracks too.
So, the only thing I see is our footprints coming up.
My guess is whatever killed this thing,
put it on top of its shoulder or whatever and ran off.
I mean...
Do you wanna keep looking around this area or--
Yeah, I definitely do, because I feel like--
-[Bryce] All right. -[rustling]
[Bryce] Did you hear that? [Ronny] Yeah.
[Bryce] Ronny, break out the thermals.
[Ronny] Okay.
[suspenseful music playing]
[Bryce] All clear.
We should head in that direction.
Okay.
[tense music playing]
[Bryce] Be careful.
We've seen what this creature's capable of.
[suspenseful music playing]
It's been a couple of hours since we've found
the remains of something torn apart,
not too far from here.
Now, we're in an area where they couldn't have gone too far.
-[Bryce] You've seen this? -[Ronny] What the...
[Bryce] The sun's already up, man.
[Ronny] Holy crap.
Geez.
[Bryce] Yeah.
The Alaskan nights are getting shorter and shorter.
Whatever tore apart that animal up there,
if it's nocturnal,
we still have about 45 minutes until daylight comes through.
And we know that that last hour of hunting time
they're gonna be the most active.
So, we wanna make sure that we're checking out this entire area.
-[birds chirping] -[Ronny] You can hear the birds
starting to wake up in the morning now.
[Bryce] I'm exhausted.
[Ronny] Yeah, me too.
Alaska's kicking our ass.
[tense music playing]
The snow is crazy.
Sometimes you get to walk on top,
sometimes it just drops you.
[Mireya] Yeah.
[narrator] After hiking all night
with only a short rest,
Russell and Mireya have reached the ice field
at the termination of the river
that the team is following.
Any kind of tracks would stand out like a sore thumb.
And I haven't seen anything fresh.
Not for this entire day.
We know something big is heading in this direction
because Bryce spotted it on that fixed-wing drone,
but whatever it was, has been able to avoid our detection.
I've never seen anything be able to move through the snow
without leaving tracks.
That completely defies logic.
[Mireya] Wow. Look at that glacier.
[Russell] Oh, man.
Is that a river right in front of it?
I mean, there's nothing.
-[Mireya] No. -You see that whole field?
There's not a single track, not even old stuff.
I... I'm...
I wouldn't have to be a good tracker
to be able to look across this whole field right here.
There's not a single footprint,
not a track [indistinct] nothing.
I mean, the thing is, if any...
if anything did come through here
you just hit this big wall.
-[Russell] Yeah. -[Mireya] And freezing cold water.
I'm not sure what would wanna move through that.
We know that something is out here
because we saw it on the fixed-wing drone.
[Russell] Right. Right.
I know we haven't seen any tracks,
but maybe we just choose a direction
and keep going down that path
and see if we see anything else.
Yeah, we can get up into that tree line.
I definitely don't think we should give up on this place.
[cameraman speaking]
Oh, yeah, right? What the [bleep].
Oh, right here. You see it?
What the [bleep] you see it?
-[Mireya] What are you seeing? -You didn't see it?
No. What was it?
It was some kind of figure over there on the ridge,
just kind of dropping over the horizon.
I don't know what that was on that ridgeline,
but I swear I saw something.
And my gut tells me that's the exact same thing
that Bryce spotted on that fixed-wing drone.
Oh, my God, it's moving.
[Mireya] What would be up there?
I have no idea.
What did it look like to you?
[cameraman speaking]
I say we try to find a way to get up there.
Let's go check it out.
It may seem counterintuitive
for something to try and hide on a giant sheet of ice,
but glaciers can be filled with deep crevices,
and it's a place where humans rarely go.
It might actually be the perfect place to hide.
That glacier is our next target.
[tense music playing]
I've been walking for the last few hours.
Ronny and I are trying to...
kind of just track whatever made that kill last night.
Haven't had much luck.
Whatever that was was enormous.
And it had the ability to rip something apart.
[Bryce] It's like the thing just picked up and vanished.
[Ronny] Hey, Bryce.
Hey, Ron. You got something?
[Ronny] Yeah. Come check this out.
-I wanna get your take. -[Bryce] What's going on, man?
[Ronny] All right. So, this caught my eye.
I noticed that there's a little game trail
kind of coming up in this opening that goes right to the water.
[Bryce] Yeah.
[Ronny] But look right up here.
Do you see that?
-[Bryce] Is that a claw mark? -[Ronny] That's what it looks like.
Oh, wow.
Is that bear or...
[Ronny] I don't think so.
Because I don't see any other claw marks around the tree
you would normally have there climbing up.
-Yeah. Yeah. -Look how high up that is,
about 8-feet off the ground to reach that.
Look how big that looks, dude.
I can't be positive that this is the mark of a Bigfoot,
but I'm pretty sure that this isn't a bear.
They'll leave parallel lines.
And this is much different.
Whatever did this,
it looks to be really strong, big,
and the main point here is tall.
There's no way a bear would make this.
You know, this idea that Bigfoot has claws.
I spoke with a witness who told me
he heard something outside his camper.
It sounded like claw marks,
but not like a bear that would, like, scratch.
It was more... [makes sound]
all along the whole trailer.
[Bryce] This is it, man.
[Ronny] It doesn't look like bear.
This is something large, strong.
Looks like some kind of a marker, man.
Like... Like marked here.
We wouldn't necessarily see it,
but maybe some other creatures of the same kind
would recognize this is where water is.
This is what made that kill,
and it's moving through this path.
I feel like it's pointing us in this direction down here by the river.
And that means better visible tracks.
[tense music playing]
[Bryce] I feel like we're so close.
Here. Let's go down here.
Watch yourself.
-[bleep]. -Nothing.
No tracks. It's too rocky.
[bleep].
[Ronny] Well, I can only hope that Russ and Mireya
are having better luck than us.
[suspenseful music playing]
[Mireya] Oh, wow. Look at this.
[Russell] This is right below where I saw it.
[narrator] In pursuit of whatever they spotted on top of the ridgeline,
Russell and Mireya have completed the dangerous climb
to the top of the glacier.
[Russell] If this thing escapes into the interior,
we'll never find it.
This is our one and only shot.
I can't imagine we've ever been this close.
We need to close that gap.
[Mireya] Oh, [bleep].
[Russell] I can't believe how much colder it is up here.
It would need a lot of hair.
[Mireya] I mean, this is a...
this is a really brutal environment
for any animal to live in, really.
A glacier doesn't make sense
as an area for a large primate to live.
But if it's being used as a conduit
to another area or as a place to hide,
then I can see it being a possibility.
[Russell] You know, growing up,
did a lot of hunting and we went through a lot of these snow areas.
But getting on this glacier, this is no joke.
Something with a padded foot like a bear even
would be very difficult to track through this stuff.
So, this makes it tough.
-[Mireya] There's water. -[Russell] Yeah.
We know most animals will follow those waterways.
And I'm betting that Bigfoot would do the same.
When there's nothing else to track,
nature and the wildlife remain.
[suspenseful music playing]
[Mireya speaking]
[Russell] Wow!
[Mireya] It's an ice cave.
I mean, that could be a shelter.
You got that right.
If Bigfoot is here,
this is where it could be hiding.
[suspenseful music playing]
[Russell speaking]
[Mireya] Oh, wow. Oh, my God.
It gets really tight here.
[Russell] Get out of your way here.
Something must have come through here.
A glacier is in constant motion.
And an ice cave like this can form quickly
and go on for miles.
We have no idea when this was formed
or even how stable it is,
but at this point, it's the only logical place
that an animal would run to
from the position that it was spotted.
There's the water.
[Russell] This is a huge find.
Because if an animal is gonna survive
in this type of environment,
this is exactly the type of shelter it's gonna need.
[Mireya] So, let's try and look for some tracks.
Not only is this cave a good spot for a shelter,
but it's also a good escape route.
The amount of running water in this cave
will match the sound of anything coming through here,
as well as erase any footprints of anything left behind.
[suspenseful music playing]
[Mireya] You seeing anything, Russ?
[Russell] Mireya, I'm not seeing anything on the standby at all.
[Mireya] Let's keep moving.
Look at how this opens up.
Wow.
Look at that.
[suspenseful music playing]
Whatever we're tracking is on its way to the interior
and it's gonna keep moving south
where they're gonna get more darkness.
We're talking about a mountainous landscape
three times the size of Texas.
We wouldn't be able to find it in that vast landscape.
We have no choice but to get to it first.
And our chances of catching something on foot are nonexistent.
[producer speaking]
[Mireya] That option we discussed earlier, is it still a possibility?
[producer speaking]
[suspenseful music playing]
[man] Let's go.
[suspenseful music playing]
[Mireya speaking]
[narrator] Their hope is to spot the creature they're tracking
before it reaches the great expanse of the interior.
[man speaking]
[Russell] Once we're out the snowfield
and under the dense forest, we've lost our chance.
[Mireya] The bright snow is the perfect contrast.
Anything walking on it will stick out like a sore thumb.
[Russell] Are you seeing anything at all down there?
[suspenseful music playing]
[Mireya] I don't see any movement.
[Russell] Oh, man.
[suspenseful music playing]
[Russell] Not a single sign of life.
[Mireya] Nothing.
Oh, no.
[Russell] There's the interior.
Can we flip around and take another look?
Crap.
[suspenseful music playing]
[Mireya] I'm still not seeing anything.
[Russell] Unbelievable.
Dammit.
[suspenseful music playing]
The whole way that science works
is that you test and you retest
and you make mistakes and you fail
and you don't give up.
You keep pushing because from every one of those mistakes
and every one of those failures comes a lesson
and comes the ability to really build on that,
so that the next time that we're out here,
we're gonna be that much stronger.
And at the end of the day,
we're not coming out of this expedition empty-handed.
We're gonna take all these lessons with us,
and that is gonna get us one step closer.
[tense music playing]
So, the team has gone home.
And as usual, I'm taking a second look
at everything that we captured out in the field.
Do you remember those microphones
that Ronny and Mireya placed?
They were supersensitive,
omnidirectional microphones that are programed
to start recording whenever they pick up a sound.
And we left them out there the entire time we were there.
Needless to say, they picked up all kinds of sounds,
most of them birds and small animals.
But after a while, I was able to find something
that really captured my attention.
Take a listen to this.
[indistinct sound]
Do you hear that?
[indistinct sound]
[Bryce] I think that's a Bigfoot speaking.
[suspenseful music playing]
[Bryce] Let's play that one more time.
[indistinct sound]
I mean, that doesn't sound like any bird or animal of the forest I know.
That sounds like a human voice to me.
And here's the thing, right?
This was taken in the middle of the night.
And the entire time we were there,
we didn't run across another soul.
So, I doubt that this is some hiker or hunter.
To me, this is a Bigfoot vocalization.
So, I wanted to reach out to somebody who could make sense of this.
And I got a hold of a man named Dr. Ronald Cosper.
[narrator] After gaining his master's in linguistics
from Cornell University,
Dr. Ronald Cosper built a career
out of studying rare and complex languages.
In 2018, he published a study
based on the notorious case of Albert Ostman,
a Canadian prospector
who was allegedly kidnapped
and held captive by Bigfoot for days.
Based on the testimony of Ostman,
Cosper believes he has translated
several words spoken by the beasts.
Obviously, he's the perfect person
to talk to about this.
He said he's ready to go over his analysis.
So, let's give him a call.
[phone rings]
Ron, thank you so much for taking the time to speak with me today.
-I really appreciate it. -It's a pleasure.
I've been really chomping at the bit to speak with you.
I know we sent you those possible Bigfoot audio recordings.
I'm dying to get your feedback.
What do you make of these?
Well, I was able to transcribe it.
It sounded quite hominid to me.
In other words, either humans or near human.
Wow.
And I was able to hear the sounds
and know where they were articulated in the mouth.
Got you.
Was there anything that you discerned as possible words?
Well, I heard something like "Waves, Flat, Kumba ".
Interesting.
[Ronald] But again, what the conditions were is another matter.
How far away, how much noise there was.
Yeah, it's interesting.
I mean, we can only guess at it,
but we were tracking something,
and then we get these audio files.
What did you think you were following?
Was it two individuals or...
Did you pick up more than one creature, Ron?
-Yes. -Really?
I thought the final utterance
was said by a different individual
than the first part of it.
You're kidding.
The voice that's something like, "Waves, Flat"
seemed to be a different voice
from the one that answered "Kumba."
Ron, you just blew my mind.
Contextually, that makes sense,
because, you know, when they were out in the field,
they felt that they were tracking more than one, uh,
by the prints that they were able to see
and just the activity that was taking place around them.
And now, you're telling us that through your expertise,
you possibly hear more than one,
especially at the end.
Ron, let me just ask you,
do you think these creatures we call Bigfoot
are capable of language?
Sure. It wouldn't surprise me.
In the reports that I have seen with the Yowie in Australia.
You mean the Australian version of Bigfoot, of course?
[Ronald] Right.
They seem to engage in something like language.
And when they are in a group, when there's more than one.
Oh, wow.
And that seems to be what we're coming up with here.
That language is used when there is a group.
I think that's incredible.
Thank you for looking at these.
I appreciate your wealth of knowledge.
Well, thank you.
It was a pleasure.
Well, that was incredible.
That confirms, uh,
what I felt that I already knew
that there was, in fact, more than one creature.
But what's even more important
is that they were possibly communicating.
It's incredible to think that
we are walking away from Alaska
with possible audio evidence of Bigfoot speech.
And more than that, possible video evidence,
3D scans of footprints, and handprints,
more audio evidence, screams, and howls.
In other words, our work is just beginning.
[suspenseful music playing]
[Bryce] I think this was one of the most
challenging expeditions any of us have ever been on.
The weather, the terrain, the wildlife.
But this expedition was also our most effective.
The bounty of evidence we collected
is gonna give us a huge leap forward
to confirming the existence of Bigfoot.
If that means that we need to go
to an even more dangerous location
or come back here to Alaska?
Then that's exactly what we're gonna do.
