Would you like to inspect the original subtitles? These are the user uploaded subtitles that are being translated:
1
00:00:05,288 --> 00:00:09,342
They didn't
expect to see what they saw.
2
00:00:11,277 --> 00:00:15,498
And when they saw it, they
could never forget it.
3
00:00:21,988 --> 00:00:23,807
Ferdinand Hayden was
hired to lead a team
4
00:00:23,840 --> 00:00:25,258
into the Northwest Territories.
5
00:00:27,927 --> 00:00:30,163
And the 32 men headed west.
6
00:00:35,952 --> 00:00:37,554
They weren't here to
protect Yellowstone.
7
00:00:38,688 --> 00:00:42,108
They were here to tear it to
shreds in the name of progress.
8
00:00:43,276 --> 00:00:48,364
Gold interests, railroad
barons, Congress.
9
00:00:50,283 --> 00:00:53,086
Powerful people wanted
this land for themselves.
10
00:00:57,223 --> 00:00:59,559
But something happened during
their three month journey,
11
00:01:02,245 --> 00:01:07,267
and slowly but surely,
their mission changed.
12
00:01:09,969 --> 00:01:12,138
So as we celebrate
the 150th anniversary
13
00:01:12,172 --> 00:01:14,207
of Yellowstone National Park,
14
00:01:15,225 --> 00:01:19,095
we take a look back
in time at the events
15
00:01:19,129 --> 00:01:24,100
that led to the preservation
of this magical place.
16
00:02:29,766 --> 00:02:31,484
What's the day?
17
00:02:31,518 --> 00:02:33,386
April 25th, 26th?
18
00:02:34,904 --> 00:02:37,207
Most the country's thawing out
19
00:02:37,240 --> 00:02:41,144
celebrating the arrival of
spring, but not here, man.
20
00:02:47,150 --> 00:02:49,219
This is Yellowstone,
eight months a year.
21
00:03:00,096 --> 00:03:02,265
You know, the crazy
thing is that 98%
22
00:03:02,298 --> 00:03:05,218
of the people who come to visit
will never see it like this.
23
00:03:07,136 --> 00:03:09,189
If you ask me, this
is a way to do it.
24
00:03:10,607 --> 00:03:11,357
It's perfect.
25
00:03:12,842 --> 00:03:14,127
It's just perfect.
26
00:03:19,165 --> 00:03:22,302
Ferdinand Hayden tried to
survey this area in 1862.
27
00:03:25,538 --> 00:03:26,289
Planned it perfectly.
28
00:03:26,322 --> 00:03:29,075
You know, he came
out in the summer,
29
00:03:29,108 --> 00:03:31,744
but then a huge
storm in late June
30
00:03:31,778 --> 00:03:33,246
made the mountains impassable.
31
00:03:34,330 --> 00:03:37,116
Took him nine more years
to make it back here.
32
00:03:38,701 --> 00:03:40,119
It's a good thing he did.
33
00:03:59,339 --> 00:04:01,441
Yellowstone in the winter
is a thing of beauty.
34
00:04:14,187 --> 00:04:17,307
On an average year, 150
inches of snow will fall.
35
00:04:19,092 --> 00:04:22,262
And at higher elevations
it's often twice that.
36
00:04:24,163 --> 00:04:27,400
More than six months a
year it looks like this.
37
00:04:33,823 --> 00:04:35,675
Even the summer
months aren't safe
38
00:04:35,708 --> 00:04:37,210
from the occasional snowfall.
39
00:04:50,390 --> 00:04:53,359
In one of Yellowstone's most
spectacular winter sites
40
00:04:54,327 --> 00:04:56,145
diamond dust floats
through the air
41
00:04:56,179 --> 00:04:58,665
like a cloud of tiny mirrors.
42
00:05:06,205 --> 00:05:09,275
It gets so cold here that
water vapor crystallizes.
43
00:05:19,952 --> 00:05:21,354
It is both beautiful,
44
00:05:25,641 --> 00:05:26,426
and cruel.
45
00:05:38,137 --> 00:05:41,174
Some will endure its challenges,
46
00:05:44,594 --> 00:05:48,281
while others seek out safe
havens in lower elevations.
47
00:05:51,417 --> 00:05:55,154
Some will burrow in dens
and wait out the season.
48
00:06:05,081 --> 00:06:06,833
While others thrive in a wild
49
00:06:06,866 --> 00:06:08,351
that has turned in their favor.
50
00:06:16,759 --> 00:06:18,177
But one thing is certain,
51
00:06:22,181 --> 00:06:24,417
in Yellowstone winner
cannot be ignored.
52
00:06:43,770 --> 00:06:45,688
The American bison
is the largest
53
00:06:45,721 --> 00:06:47,340
land mammal in North America.
54
00:06:50,943 --> 00:06:52,779
They've lived in
Yellowstone continuously
55
00:06:52,812 --> 00:06:54,480
since prehistoric times.
56
00:06:58,267 --> 00:07:00,153
You ever look at
a bison and wonder
57
00:07:00,186 --> 00:07:02,288
why they have those
massive humps?
58
00:07:04,307 --> 00:07:07,393
It's a perfectly
evolved adaptation to
deal with the snow.
59
00:07:09,262 --> 00:07:12,014
Most ungulates forge
for grass by breaking up
60
00:07:12,048 --> 00:07:13,466
the snow with their hooves.
61
00:07:16,135 --> 00:07:18,204
That won't work
here in Yellowstone.
62
00:07:18,888 --> 00:07:21,390
The snow's too heavy, too deep.
63
00:07:23,075 --> 00:07:25,344
So the bison evolve massive
neck muscles that power
64
00:07:25,378 --> 00:07:28,347
their enormous head side
to side like a snowplow
65
00:07:29,732 --> 00:07:31,400
exposing the grass underneath.
66
00:07:32,768 --> 00:07:34,020
The temperature here can get
67
00:07:34,053 --> 00:07:37,190
as low as negative 60
degrees Fahrenheit.
68
00:07:38,141 --> 00:07:40,226
So it's good to
pack a heavy coat.
69
00:07:43,212 --> 00:07:46,466
The bison's is so heavy
that their body heat
70
00:07:46,499 --> 00:07:49,235
doesn't even melt the snow
that collects on their fur.
71
00:07:51,120 --> 00:07:53,072
Their skin thickens in winter
72
00:07:54,357 --> 00:07:57,210
and fatty deposits keep
them warm from the inside.
73
00:08:03,883 --> 00:08:06,786
But even the perfectly
adapted bison have
74
00:08:06,819 --> 00:08:08,387
to fight to survive
every winter.
75
00:08:14,610 --> 00:08:16,028
If it snows too much,
76
00:08:19,832 --> 00:08:21,284
they can't access the grass
77
00:08:21,317 --> 00:08:23,469
they need to fuel
their massive bodies.
78
00:08:41,103 --> 00:08:43,506
When the Hayden expedition
first came to Yellowstone
79
00:08:44,373 --> 00:08:46,526
they took note not only
of the largest herd
80
00:08:46,559 --> 00:08:51,197
that roamed the valleys,
but also the large number
81
00:08:51,230 --> 00:08:53,499
of dead bison that fed
the parks predators.
82
00:09:01,958 --> 00:09:03,776
Their left over after
the unrelenting winner
83
00:09:03,809 --> 00:09:05,211
culls the herd.
84
00:09:07,880 --> 00:09:09,665
The harsh conditions kill one
85
00:09:09,699 --> 00:09:11,350
out of 10 bison every year.
86
00:09:16,289 --> 00:09:21,327
This has become known
simply as winter kill.
87
00:09:34,957 --> 00:09:36,459
It provides
predators in the park
88
00:09:36,492 --> 00:09:40,012
with as much as 800,000
pounds of meat each winter.
89
00:09:47,036 --> 00:09:49,272
Everyone wants a
piece of the action,
90
00:09:56,062 --> 00:09:58,397
because the window of
opportunity is small.
91
00:10:00,016 --> 00:10:02,501
The next snowstorm is
usually just hours away
92
00:10:02,535 --> 00:10:06,305
and anything left uneaten
will be buried until spring.
93
00:10:19,935 --> 00:10:22,171
Hoping to avoid that fate,
94
00:10:22,204 --> 00:10:24,674
these bison endure
long migration
95
00:10:24,707 --> 00:10:26,142
to lower elevations.
96
00:10:29,328 --> 00:10:31,864
Were super heated water
beneath the surface
97
00:10:31,897 --> 00:10:33,382
melts the snow above.
98
00:10:38,921 --> 00:10:40,239
There they will find the grass
99
00:10:40,272 --> 00:10:42,375
they need to survive
until spring.
100
00:10:50,082 --> 00:10:52,234
Every living thing
in Yellowstone spends
101
00:10:52,268 --> 00:10:55,454
at least half the year
battling the harsh conditions.
102
00:11:00,810 --> 00:11:02,228
It was something the pioneers
103
00:11:02,261 --> 00:11:05,898
on the Hayden Expedition
wanted to avoid dealing with,
104
00:11:05,931 --> 00:11:07,433
making their journey
in the summer.
105
00:11:11,687 --> 00:11:12,972
But they quickly found out
106
00:11:13,005 --> 00:11:14,790
that even the best laid plans
107
00:11:14,824 --> 00:11:16,375
can be undone quickly here.
108
00:11:19,862 --> 00:11:21,180
And so did I.
109
00:11:28,020 --> 00:11:31,323
You know, sometimes I
find myself wondering
110
00:11:32,675 --> 00:11:34,126
whose brilliant idea was this.
111
00:11:35,327 --> 00:11:39,115
Usually when that
happens, I'm the culprit.
112
00:11:39,148 --> 00:11:42,435
But man, Yellowstone
and the stone cold,
113
00:11:43,936 --> 00:11:45,538
it's no country for
the faint of heart.
114
00:11:47,907 --> 00:11:50,292
I mean, the animals
have had millions
115
00:11:50,326 --> 00:11:52,495
of years to adapt
to the conditions.
116
00:11:52,528 --> 00:11:56,082
And even still, there's
plenty that don't make it.
117
00:11:58,200 --> 00:12:00,386
Being here makes me
think about George Allen.
118
00:12:03,806 --> 00:12:05,608
One of the two
journals to survive
119
00:12:05,641 --> 00:12:07,243
through time was Allen's.
120
00:12:07,276 --> 00:12:10,379
He was a geologist
in Hayden's mentor.
121
00:12:10,413 --> 00:12:13,349
He was one of the older
gentlemen on the expedition.
122
00:12:14,700 --> 00:12:16,035
And sometime in the,
123
00:12:16,919 --> 00:12:19,555
sometime in late July in 1871,
124
00:12:19,588 --> 00:12:23,292
another big storm blew through
and it buried everything.
125
00:12:23,325 --> 00:12:26,195
And Alan was in
his tent shivering,
126
00:12:28,013 --> 00:12:29,832
kinda same way as
I am right now.
127
00:12:29,865 --> 00:12:31,083
And he wrote about,
128
00:12:32,084 --> 00:12:34,053
he wrote about how
miserable he was.
129
00:12:34,870 --> 00:12:37,139
Wasn't sure he'd
survived the expedition.
130
00:12:38,007 --> 00:12:39,492
He left the next day.
131
00:12:42,812 --> 00:12:44,230
That's probably a good decision.
132
00:12:46,766 --> 00:12:48,200
Probably a really good decision.
133
00:12:58,561 --> 00:13:02,014
Yellowstone National Park
is an easy place to visit,
134
00:13:03,032 --> 00:13:06,352
but living here, that's
anything but easy.
135
00:13:09,121 --> 00:13:11,240
Every species that
has managed to survive
136
00:13:11,273 --> 00:13:14,093
the winters has only done
so through adaptation.
137
00:13:34,196 --> 00:13:37,249
These river otters are perfectly
adapted to the conditions.
138
00:13:40,970 --> 00:13:43,455
Thick hair protects warm
skin from cold water.
139
00:13:50,379 --> 00:13:52,531
That's why their pelts
were so sought after
140
00:13:53,766 --> 00:13:55,017
by the hunters and trappers
141
00:13:55,050 --> 00:13:56,001
who made their way to
the Yellowstone region
142
00:13:56,035 --> 00:13:58,070
long before Hayden and his men.
143
00:14:01,991 --> 00:14:03,976
The otter furs
were in high demand
144
00:14:04,009 --> 00:14:06,779
by the wealthiest
people back east,
145
00:14:06,812 --> 00:14:07,930
because of the
warmth they provided
146
00:14:07,963 --> 00:14:10,115
and the luster of the fur.
147
00:14:12,968 --> 00:14:14,870
Today, the otters in Yellowstone
148
00:14:14,904 --> 00:14:16,455
don't have to worry
about trappers.
149
00:14:18,841 --> 00:14:20,726
Their battle is
keeping themselves fed
150
00:14:20,759 --> 00:14:22,177
during the cold winter months.
151
00:14:28,751 --> 00:14:29,585
The steady supply of fish
152
00:14:29,618 --> 00:14:33,255
and open water can only be
counted on in the warmer months.
153
00:14:39,912 --> 00:14:41,480
The winter freeze
chokes off the river,
154
00:14:43,265 --> 00:14:46,285
cutting off the food supply for
the mother and her two pups.
155
00:14:58,180 --> 00:15:00,516
They go from one hole
in the ice to another
156
00:15:00,549 --> 00:15:01,984
in search of a meal.
157
00:15:09,058 --> 00:15:11,744
But with every fish they
pull from the icy depths,
158
00:15:11,777 --> 00:15:13,145
the supplies lessened.
159
00:15:14,313 --> 00:15:17,433
And soon this family will need
to find a new place to fish.
160
00:15:20,019 --> 00:15:22,271
River otters may reign
supreme in water,
161
00:15:22,304 --> 00:15:25,190
but on land it's a
different story together.
162
00:15:26,175 --> 00:15:29,295
Here they go from
hunter to hunted.
163
00:15:32,031 --> 00:15:33,882
Alternating between
hopping and sliding,
164
00:15:33,916 --> 00:15:35,367
they can reach speeds
165
00:15:35,401 --> 00:15:38,203
of 15 miles per hour
through the heavy snow.
166
00:15:43,726 --> 00:15:45,911
They'll need that speed
167
00:15:45,945 --> 00:15:47,479
as they search for
a new fishing hole.
168
00:15:49,064 --> 00:15:51,050
And predators are abound.
169
00:16:01,260 --> 00:16:04,830
While the otter family struggles
against the cold and snow,
170
00:16:04,863 --> 00:16:06,265
wolfs thrive.
171
00:16:18,143 --> 00:16:21,146
In these conditions,
they're top dog.
172
00:16:30,906 --> 00:16:33,125
But winter brings
territorial disputes,
173
00:16:33,976 --> 00:16:37,046
and at times unbridled savagery.
174
00:16:40,983 --> 00:16:43,185
This is when strong packs expand
175
00:16:44,953 --> 00:16:47,106
and weak packs die off.
176
00:16:48,490 --> 00:16:51,326
The druid pack once rained
supreme in this area,
177
00:16:52,011 --> 00:16:54,179
only to wither in recent years
178
00:16:54,213 --> 00:16:56,348
as Molly's pack has
taken the throne.
179
00:16:58,133 --> 00:17:01,170
But with success comes problems
180
00:17:01,203 --> 00:17:04,223
and Molly's pack already
finds itself in turmoil.
181
00:17:09,595 --> 00:17:13,248
Rival packs are constantly on
the lookout for new territory.
182
00:17:15,084 --> 00:17:18,220
Recently a pack of 15 wolves
traveled 40 miles outside
183
00:17:18,253 --> 00:17:21,140
of their territory to
take on another pack.
184
00:17:22,207 --> 00:17:25,177
Securing territory is
key to their survival.
185
00:17:26,145 --> 00:17:28,197
More land means more
hunting grounds.
186
00:17:46,415 --> 00:17:51,353
In winter, elk is the main
thing on the menu for this pack.
187
00:17:56,041 --> 00:17:59,094
90% of their diet is elk
during this cold period.
188
00:18:03,132 --> 00:18:05,350
An elk cow has been
separated from the harem.
189
00:18:08,070 --> 00:18:10,322
And even with
strength in numbers
190
00:18:10,355 --> 00:18:14,159
fighting off a wolf
pack is a hero's task.
191
00:18:17,012 --> 00:18:18,997
The wolves move
on to high ground
192
00:18:20,182 --> 00:18:24,286
and when the sun goes
down, they will strike.
193
00:18:26,038 --> 00:18:29,174
When they do, they'll
announce it to the world.
194
00:18:52,881 --> 00:18:54,082
The wolf's ability to hunt
195
00:18:54,116 --> 00:18:56,735
elk doesn't just
keep them well fed.
196
00:18:56,768 --> 00:18:58,403
It keeps the park in balance.
197
00:19:00,088 --> 00:19:02,274
By thinning out
oversized elk populations
198
00:19:02,307 --> 00:19:05,344
and cutting down the
weak and sick among them
199
00:19:05,377 --> 00:19:09,114
they leave stronger, more
resilient elk herds behind.
200
00:19:11,049 --> 00:19:13,152
The elk cow has
made a good meal,
201
00:19:14,520 --> 00:19:15,304
but it's not enough.
202
00:19:16,505 --> 00:19:17,372
It's never enough.
203
00:19:20,108 --> 00:19:22,327
These wolves need more
calories in the winter.
204
00:19:24,963 --> 00:19:26,348
Moving through heavy snow
205
00:19:26,381 --> 00:19:29,201
and maintaining body heat
requires more energy.
206
00:19:31,770 --> 00:19:33,305
So they're on the
prowl for more,
207
00:19:34,606 --> 00:19:36,041
and always will be.
208
00:19:37,259 --> 00:19:41,463
Like I said, it's an
easy place to visit,
209
00:19:41,496 --> 00:19:42,314
tough place to live.
210
00:19:47,052 --> 00:19:49,121
This male bobcat
is another creature
211
00:19:49,154 --> 00:19:51,323
that will fight to
survive all winter long.
212
00:19:54,026 --> 00:19:55,427
Every meal will be a battle.
213
00:20:00,983 --> 00:20:03,402
A duck, now that's good eating.
214
00:20:05,370 --> 00:20:08,156
It could keep him
fed for several days.
215
00:20:12,211 --> 00:20:15,214
He typically prowls the
conifer forest of Yellowstone.
216
00:20:16,148 --> 00:20:18,967
But desperate times call
for desperate measures.
217
00:20:19,001 --> 00:20:20,419
And he comes into
the open today.
218
00:20:24,006 --> 00:20:25,924
His small feet and short legs
219
00:20:25,958 --> 00:20:27,426
aren't built for the loose snow.
220
00:20:30,679 --> 00:20:32,147
And despite his appetite
221
00:20:32,180 --> 00:20:34,433
he's hesitant to get
into the cold water.
222
00:20:40,055 --> 00:20:41,940
Though the bobcat
is a skilled hunter
223
00:20:41,974 --> 00:20:43,342
this isn't a fair fight.
224
00:20:44,626 --> 00:20:45,477
He's out of his element.
225
00:20:51,566 --> 00:20:55,153
Finding meals will only get
harder as winter continues
226
00:20:55,187 --> 00:20:57,472
and fat stores and
energy reserves dwindle.
227
00:21:02,160 --> 00:21:04,246
And if the bobcat
is going to feed,
228
00:21:05,714 --> 00:21:08,133
all he can do is buy his time
229
00:21:08,166 --> 00:21:10,168
and wait for the
right opportunity.
230
00:21:50,776 --> 00:21:52,411
As lovely as the sight is,
231
00:21:54,179 --> 00:21:56,348
as lucid and clean
the fallen snow,
232
00:21:58,800 --> 00:22:00,152
I can't help but think
233
00:22:00,185 --> 00:22:02,187
of the chaos that
winter brings with it.
234
00:22:05,941 --> 00:22:07,326
Ever been to a bonfire?
235
00:22:08,810 --> 00:22:10,245
You know, that's how when you
236
00:22:10,278 --> 00:22:12,180
first show up people
are all spread out.
237
00:22:12,214 --> 00:22:13,815
Maybe there's a
few around the fire
238
00:22:13,849 --> 00:22:16,184
but you got some
people over here
239
00:22:16,218 --> 00:22:18,303
and you got another
group over there.
240
00:22:20,088 --> 00:22:23,241
Then it gets late
and night grows cold.
241
00:22:23,275 --> 00:22:24,926
Eventually, every last
person that's huddled
242
00:22:24,960 --> 00:22:26,278
around that fire.
243
00:22:31,466 --> 00:22:32,234
That down there,
244
00:22:33,952 --> 00:22:35,253
that's a bonfire.
245
00:22:41,910 --> 00:22:43,412
When it gets warmer
246
00:22:43,445 --> 00:22:45,313
the animals spread out
and make their way up
247
00:22:45,347 --> 00:22:47,532
the ranges all the
way to the peaks.
248
00:22:48,850 --> 00:22:50,302
Then when the snow comes,
249
00:22:51,470 --> 00:22:54,873
they head back down to
the Valley seeking refuge,
250
00:22:54,906 --> 00:22:56,391
creatures that have absolutely
251
00:22:56,425 --> 00:22:59,311
no interest in being friends
huddle around that fire.
252
00:23:01,863 --> 00:23:04,299
When it gets 30, 40
degrees below zero
253
00:23:04,332 --> 00:23:08,170
that fire dims and they
huddle even closer.
254
00:23:09,838 --> 00:23:11,323
That's when all
hell breaks loose.
255
00:23:27,923 --> 00:23:29,458
The large herds that
graze the valleys
256
00:23:29,491 --> 00:23:32,994
in spring and summer have
broken into smaller groups
257
00:23:33,028 --> 00:23:35,397
as they migrate toward
the lower elevations.
258
00:23:41,770 --> 00:23:43,288
And no one is more aware of this
259
00:23:43,321 --> 00:23:45,273
than the wolves who
track these smaller herds
260
00:23:45,307 --> 00:23:47,426
as they migrate
towards the bonfire.
261
00:24:18,106 --> 00:24:20,025
These bison have
traveled 40 miles
262
00:24:20,058 --> 00:24:21,493
to reach the geyser basin.
263
00:24:33,939 --> 00:24:37,509
For a migration that
began weeks ago.
264
00:24:37,542 --> 00:24:40,412
The steam from the thermal
vents is a welcome site,
265
00:24:46,368 --> 00:24:49,304
but the warmth of the thermals
draws in predator and prey.
266
00:25:02,050 --> 00:25:05,437
The bison herd arrives
at the geyser basin.
267
00:25:16,264 --> 00:25:18,783
The super volcano beneath
the Earth's surface fights
268
00:25:18,817 --> 00:25:20,218
against the cold above,
269
00:25:23,705 --> 00:25:25,307
sending steam outward,
270
00:25:25,340 --> 00:25:28,260
melting the snow and
exposing the grass.
271
00:25:31,863 --> 00:25:34,065
But there is a downside
to grazing here.
272
00:25:36,318 --> 00:25:39,437
The grass that grows near the
thermal has less nutrients
273
00:25:42,991 --> 00:25:45,577
and the long journey
to get here took a lot
274
00:25:45,610 --> 00:25:46,378
out of the bison.
275
00:25:52,867 --> 00:25:54,853
By the time they arrive
276
00:25:54,886 --> 00:25:56,321
they're at their weakest.
277
00:26:03,678 --> 00:26:05,230
And wolves are opportunists.
278
00:26:09,884 --> 00:26:11,486
They've traveled across
the park to greet
279
00:26:11,519 --> 00:26:16,308
the bison at the bonfire, just
like they do every winter.
280
00:26:22,280 --> 00:26:24,833
Taking on a herd of healthy
bison at full strength
281
00:26:24,866 --> 00:26:26,318
isn't worth the effort,
282
00:26:31,289 --> 00:26:33,275
but in their tired,
weakened state,
283
00:26:36,611 --> 00:26:37,362
the wolves will come.
284
00:26:43,285 --> 00:26:45,470
With the sun setting,
the attack is imminent.
285
00:26:59,951 --> 00:27:03,121
Under the cover of
darkness they strike,
286
00:27:12,981 --> 00:27:15,066
and by the time the sun rises,
287
00:27:18,820 --> 00:27:20,338
the wolves are
finishing their meal.
288
00:27:31,666 --> 00:27:32,984
They'll eat as much as 20 pounds
289
00:27:33,018 --> 00:27:35,153
of meat each on
a kill like this.
290
00:27:47,882 --> 00:27:49,434
With their bellies full,
291
00:27:49,467 --> 00:27:52,037
the wolves will leave the
bison herd alone today.
292
00:27:58,993 --> 00:28:01,012
Tonight will be a
different story.
293
00:28:13,775 --> 00:28:15,226
Back at the riverbank,
294
00:28:15,260 --> 00:28:18,329
the starving bobcat continues
his fight for survival.
295
00:28:23,685 --> 00:28:26,371
He needs a meal, and soon.
296
00:28:28,306 --> 00:28:31,743
A musk rat may not
taste as good as a duck,
297
00:28:31,776 --> 00:28:33,078
but it'll have to do.
298
00:28:34,345 --> 00:28:36,815
The semi-aquatic musk
rat builds his burrow
299
00:28:36,848 --> 00:28:38,083
on the river bank.
300
00:28:41,136 --> 00:28:46,174
Little does he know
he's being hunted.
301
00:28:51,679 --> 00:28:53,131
The bobcat was reluctant to jump
302
00:28:53,164 --> 00:28:55,366
into the freezing water
to catch the duck,
303
00:28:57,685 --> 00:28:59,053
but he's one day hungrier.
304
00:28:59,921 --> 00:29:01,389
One day more desperate.
305
00:29:29,017 --> 00:29:31,419
Another meal has slipped away.
306
00:29:33,188 --> 00:29:36,007
It's going to be a long
winter for the bobcat.
307
00:29:38,092 --> 00:29:42,380
If his luck doesn't change
soon, it may be a short one.
308
00:29:54,876 --> 00:29:57,128
At the higher elevations,
309
00:29:58,913 --> 00:30:00,799
Yellowstone's big
horn sheep fight
310
00:30:00,832 --> 00:30:02,200
their own battle every winter.
311
00:30:14,045 --> 00:30:15,964
The big horn sheep in
Yellowstone descend
312
00:30:15,997 --> 00:30:18,132
from sheep that left Siberia
313
00:30:18,166 --> 00:30:20,869
and migrated across
the Bering land bridge.
314
00:30:20,902 --> 00:30:23,054
750,000 years ago,
315
00:30:26,741 --> 00:30:28,092
they became the primary source
316
00:30:28,126 --> 00:30:31,162
of food for the
indigenous Tukudika tribe
317
00:30:31,196 --> 00:30:33,832
who lived in Yellowstone
thousands of years
318
00:30:33,865 --> 00:30:35,500
before Hayden ever
set foot there.
319
00:30:39,971 --> 00:30:42,740
Tukudika is roughly
translated to eaters
320
00:30:42,774 --> 00:30:44,075
of the mountain sheep,
321
00:30:46,961 --> 00:30:48,930
and the tribes lived
at high elevations
322
00:30:48,963 --> 00:30:50,448
where the big horn
was plentiful.
323
00:30:52,967 --> 00:30:55,303
They used the sheep
not only for food,
324
00:30:55,336 --> 00:30:58,456
but by warming their horns in
Yellowstone's thermal waters,
325
00:31:00,158 --> 00:31:02,227
they could shape them into
extremely durable bows.
326
00:31:05,046 --> 00:31:06,881
There used to be millions
of big horns spread
327
00:31:06,915 --> 00:31:09,033
across the Western
United States,
328
00:31:11,085 --> 00:31:14,105
today there are
fewer than 70,000.
329
00:31:15,974 --> 00:31:19,110
And each winter,
Yellowstone's big horn
330
00:31:19,143 --> 00:31:23,181
decide who gets to mate
this year and who doesn't.
331
00:31:25,817 --> 00:31:27,252
Through a series of battles,
332
00:31:28,219 --> 00:31:30,521
toughest males
established dominance,
333
00:31:35,927 --> 00:31:38,062
only they will have
breeding rights.
334
00:31:44,068 --> 00:31:47,088
A fully grown ram
can weigh 300 pounds,
335
00:31:48,039 --> 00:31:50,275
40 of which are
held in their horns.
336
00:31:51,960 --> 00:31:54,178
Their skulls have two
layers of cushion above
337
00:31:54,212 --> 00:31:57,282
the brain which absorb the
impact of the collision.
338
00:32:05,023 --> 00:32:06,824
The sounds of winter
are almost as incredible
339
00:32:06,858 --> 00:32:08,192
as the sights.
340
00:32:15,750 --> 00:32:17,435
Almost is incredible.
341
00:32:21,539 --> 00:32:25,076
There's something majestic
about the snow covered peaks.
342
00:32:29,514 --> 00:32:32,317
Something inspiring about
seeing the wild world.
343
00:32:36,838 --> 00:32:38,523
Unchanged by the hands of man.
344
00:32:40,975 --> 00:32:42,527
Unchanged by the hands of time.
345
00:32:57,558 --> 00:32:59,944
I don't think I'm any
different than anyone else.
346
00:32:59,978 --> 00:33:01,596
We all grew up in
different places.
347
00:33:01,629 --> 00:33:03,097
I grew up in the inner city.
348
00:33:03,131 --> 00:33:05,216
I was born in a place
called Compton, California.
349
00:33:07,301 --> 00:33:09,787
But I remember when I
got my first glimpse
350
00:33:09,821 --> 00:33:12,190
of the Rocky Mountains.
351
00:33:15,126 --> 00:33:17,378
You know, it was like the
scales came off my eyes
352
00:33:17,412 --> 00:33:21,065
and I thought could there be a
place like this in the world?
353
00:33:26,170 --> 00:33:28,890
The reality is that
America's so big,
354
00:33:28,923 --> 00:33:31,042
and Yellowstone reminds you
355
00:33:31,075 --> 00:33:33,227
of what the country
might have looked
356
00:33:33,261 --> 00:33:36,147
like before there was any
outsiders that ever came,
357
00:33:37,265 --> 00:33:39,517
and to know that the
rivers still flow
358
00:33:40,818 --> 00:33:42,253
and these mountains still stand.
359
00:33:46,140 --> 00:33:49,360
There is something that
we should be thankful for,
360
00:33:50,962 --> 00:33:53,948
the human will to
convince other people
361
00:33:53,981 --> 00:33:55,533
that this is worth keeping.
362
00:33:58,002 --> 00:34:00,238
It wasn't a battle
and it was uphill
363
00:34:02,073 --> 00:34:05,126
but it was about one
man who believed he had
364
00:34:05,159 --> 00:34:09,197
an idea about himself,
so much so that he knew
365
00:34:09,230 --> 00:34:12,366
if given the chance he
could change the world.
366
00:34:17,338 --> 00:34:20,825
Ferdinand Hayden's
determination to convince the US
367
00:34:20,858 --> 00:34:22,877
Congress to protect Yellowstone
368
00:34:22,910 --> 00:34:25,079
rather than let it
be torn apart is
369
00:34:25,113 --> 00:34:27,231
the reason we can tell
these stories today.
370
00:34:28,299 --> 00:34:32,270
It's the reason that
the bobcats and bison,
371
00:34:35,139 --> 00:34:38,910
and wolves have this
pristine landscape to roam,
372
00:34:38,943 --> 00:34:43,114
to breed, to fight,
and to survive.
373
00:34:49,036 --> 00:34:51,239
Survival is the name
of the game in winter.
374
00:34:57,028 --> 00:34:59,013
The river otters continue
their desperate trek
375
00:34:59,046 --> 00:35:01,132
to find a new food source.
376
00:35:04,786 --> 00:35:06,053
They've made their way
377
00:35:06,087 --> 00:35:08,139
to a place where the
water never freezes.
378
00:35:11,776 --> 00:35:13,044
The upper falls.
379
00:35:17,081 --> 00:35:20,051
Water crashing from the
falls churns the pool below,
380
00:35:21,018 --> 00:35:23,020
preventing it from freezing.
381
00:35:29,110 --> 00:35:32,063
But the fishing hole
is 109 feet down.
382
00:35:39,887 --> 00:35:42,073
In the summer of 1871,
383
00:35:43,374 --> 00:35:45,693
Hayden and his men used
ropes to traverse the falls
384
00:35:45,726 --> 00:35:47,245
as they explored Yellowstone.
385
00:35:51,449 --> 00:35:54,385
Believe it or not, these
otters don't have any ropes.
386
00:36:01,292 --> 00:36:04,095
But the snow creates
another opportunity.
387
00:36:13,104 --> 00:36:15,406
Mom teaches the pups
the art of sledding.
388
00:36:44,252 --> 00:36:47,071
The otter family makes it
to their new fishing hole.
389
00:36:51,309 --> 00:36:56,280
They're back in their
element, and soon they'll die.
390
00:37:09,176 --> 00:37:12,029
They found a workaround
for the winter conditions
391
00:37:12,063 --> 00:37:14,098
and food here will be abundant.
392
00:37:48,649 --> 00:37:50,301
The bobcat isn't so lucky,
393
00:38:04,248 --> 00:38:06,384
the pangs of hunger
are overwhelming
394
00:38:08,269 --> 00:38:10,454
and he is in desperate
search of food.
395
00:38:29,123 --> 00:38:31,309
At this point, he'll
settle for anything.
396
00:38:40,618 --> 00:38:41,485
It's all or nothing.
397
00:38:45,706 --> 00:38:47,291
The time to strike is now.
398
00:39:21,809 --> 00:39:24,228
Finally, the bobcat
has his dinner.
399
00:39:32,186 --> 00:39:33,971
His chances of
surviving the winter
400
00:39:34,004 --> 00:39:35,439
just got a little better.
401
00:39:47,068 --> 00:39:49,370
Yellowstone in winter is iconic.
402
00:39:54,508 --> 00:39:55,459
A world of ice,
403
00:39:58,579 --> 00:39:59,363
and fire.
404
00:40:05,035 --> 00:40:06,303
A world where every creature
405
00:40:06,337 --> 00:40:09,023
fights their own battle
every single day.
406
00:40:20,184 --> 00:40:22,253
But if not for the
pioneers who made
407
00:40:22,286 --> 00:40:25,339
the decision to protect
this place 150 years ago,
408
00:40:27,875 --> 00:40:29,493
we'd never know that
it even existed.
409
00:40:41,806 --> 00:40:43,390
You know, I don't know
410
00:40:43,424 --> 00:40:45,209
if there's another place
on Earth that gives you
411
00:40:45,242 --> 00:40:47,111
the evocative
spectacle of nature
412
00:40:47,144 --> 00:40:48,546
that Yellowstone
does in the snow.
413
00:40:51,132 --> 00:40:53,250
And being here,
seeing it firsthand,
414
00:40:54,752 --> 00:40:56,303
makes me wonder what if,
415
00:40:57,455 --> 00:41:00,458
what if Hayden and his
team never came here?
416
00:41:02,176 --> 00:41:03,844
What if they'd
been delayed a year
417
00:41:03,878 --> 00:41:06,213
and people had
set up gold mines?
418
00:41:10,267 --> 00:41:13,504
What if their plan to protect
this place didn't work?
419
00:41:14,972 --> 00:41:16,474
And the truth was,
it almost didn't.
420
00:41:18,209 --> 00:41:20,478
There was a photographer
named Anton Sean Burn.
421
00:41:25,065 --> 00:41:26,233
He was part of the expedition
422
00:41:26,267 --> 00:41:28,519
and he was a big part
of Hayden's plan.
423
00:41:30,037 --> 00:41:32,022
He took all the notes
they were gonna use
424
00:41:32,056 --> 00:41:34,375
to create the maps that
they were gonna present
425
00:41:34,408 --> 00:41:38,779
to Congress and those
maps were gonna be crucial
426
00:41:38,812 --> 00:41:40,297
in getting
Yellowstone protected,
427
00:41:41,298 --> 00:41:43,317
then just days before
he was gonna meet,
428
00:41:44,468 --> 00:41:48,439
meet Hayden in Washington
DC, he killed himself.
429
00:41:49,840 --> 00:41:51,909
Turns out that six days earlier
430
00:41:51,942 --> 00:41:54,628
the great Chicago
fire had destroyed
431
00:41:54,662 --> 00:41:58,082
a huge amount of the data
collected on the expedition.
432
00:41:59,867 --> 00:42:00,968
It was tragic, of course,
433
00:42:01,001 --> 00:42:04,688
but it was a
disaster for Hayden,
434
00:42:04,722 --> 00:42:06,257
and he needed to act fast.
435
00:42:09,260 --> 00:42:12,096
Hayden knew that a watershed
moment was upon him.
436
00:42:13,214 --> 00:42:15,266
He knew that the wolves
were at the gates
437
00:42:15,299 --> 00:42:18,319
and the snow was the only
thing keeping them out.
438
00:42:20,588 --> 00:42:22,289
For when spring arrived,
439
00:42:22,323 --> 00:42:25,092
the destruction of Yellowstone
would begin in force.
440
00:42:34,184 --> 00:42:36,453
The vandals who are waiting
to enter this wonderland
441
00:42:36,487 --> 00:42:39,757
will in a single season
be spoiled beyond recovery
442
00:42:39,790 --> 00:42:41,492
these remarkable curiosities,
443
00:42:43,010 --> 00:42:44,428
which have required
all the cunning skill
444
00:42:44,461 --> 00:42:47,281
of nature of thousands
of years to prepare.
445
00:42:52,286 --> 00:42:55,356
With that said, Hayden
cast the first stone
446
00:42:55,389 --> 00:42:57,508
to protect the land
that he'd grown to love.
447
00:43:14,275 --> 00:43:16,010
You know, Hayden
predicted they would come
448
00:43:16,043 --> 00:43:19,880
in droves to destroy this
place once the winter
449
00:43:19,913 --> 00:43:21,432
released the land
from its clutches.
450
00:43:22,349 --> 00:43:26,770
His words, not mine,
but boy was he right.
451
00:43:26,804 --> 00:43:30,274
Spring finally came in 1872,
452
00:43:31,692 --> 00:43:33,344
and one after another,
453
00:43:33,377 --> 00:43:35,879
the profiteers started
filing their claims,
454
00:43:35,913 --> 00:43:38,415
100, 150, 200 acres at a time.
455
00:43:40,000 --> 00:43:42,169
The claims poured into
the public land office.
456
00:43:43,304 --> 00:43:47,324
Everything from gold to silver
to medicinal spring water.
457
00:43:47,358 --> 00:43:51,061
Every damn thing we've seen
had a claim filed on it.
458
00:43:52,946 --> 00:43:54,431
And the miracle of it all was
459
00:43:54,465 --> 00:43:58,319
that every single claim
that was filed that year,
460
00:43:59,803 --> 00:44:01,288
every single one was denied.
461
00:44:05,893 --> 00:44:07,461
Because you see,
eight days earlier,
462
00:44:07,494 --> 00:44:11,432
President Ulysses S. Grant
signed Hayden's bill into law.
463
00:44:12,983 --> 00:44:14,918
The National Park
system was created
464
00:44:14,952 --> 00:44:17,154
just in the nick of time,
465
00:44:18,255 --> 00:44:22,026
and Yellowstone was
saved by eight days.
466
00:44:24,728 --> 00:44:25,863
You know, that's
not a fairytale.
467
00:44:25,896 --> 00:44:28,949
It's not a Hollywood ending,
468
00:44:28,982 --> 00:44:31,035
it's just how close
it all was to going.
469
00:44:32,553 --> 00:44:35,472
No one alive today would even
know this land even existed.
470
00:44:39,143 --> 00:44:40,511
Thank God for that snow, huh?
471
00:44:49,870 --> 00:45:00,029
- Let's go, pal.
