1
00:00:01,451 --> 00:00:04,041
(light music)
2
00:00:05,288 --> 00:00:09,338
- [Kevin] They didn't
expect to see what they saw.
3
00:00:11,277 --> 00:00:15,497
And when they saw it, they
could never forget it.
4
00:00:21,988 --> 00:00:23,808
Ferdinand Hayden was
hired to lead a team
5
00:00:23,840 --> 00:00:25,260
into the Northwest Territories.
6
00:00:27,927 --> 00:00:30,157
And the 32 men headed west.
7
00:00:35,952 --> 00:00:37,552
They weren't here to
protect Yellowstone.
8
00:00:38,688 --> 00:00:42,108
They were here to tear it to
shreds in the name of progress.
9
00:00:43,276 --> 00:00:48,356
Gold interests, railroad
barons, Congress.
10
00:00:50,283 --> 00:00:53,093
Powerful people wanted
this land for themselves.
11
00:00:57,223 --> 00:00:59,563
But something happened during
their three month journey,
12
00:01:02,245 --> 00:01:07,265
and slowly but surely,
their mission changed.
13
00:01:09,969 --> 00:01:12,139
So as we celebrate
the 150th anniversary
14
00:01:12,172 --> 00:01:14,212
of Yellowstone National Park,
15
00:01:15,225 --> 00:01:19,095
we take a look back
in time at the events
16
00:01:19,129 --> 00:01:24,099
that led to the preservation
of this magical place.
17
00:01:37,881 --> 00:01:41,271
(upbeat majestic music)
18
00:02:29,766 --> 00:02:31,476
What's the day?
19
00:02:31,518 --> 00:02:33,388
April 25th, 26th?
20
00:02:34,904 --> 00:02:37,214
Most the country's thawing out
21
00:02:37,240 --> 00:02:41,140
celebrating the arrival of
spring, but not here, man.
22
00:02:43,980 --> 00:02:47,120
(upbeat majestic music)
23
00:02:47,150 --> 00:02:49,220
This is Yellowstone,
eight months a year.
24
00:02:53,406 --> 00:02:55,406
(wolf howls)
25
00:03:00,096 --> 00:03:02,266
You know, the crazy
thing is that 98%
26
00:03:02,298 --> 00:03:05,218
of the people who come to visit
will never see it like this.
27
00:03:07,136 --> 00:03:09,186
If you ask me, this
is a way to do it.
28
00:03:10,607 --> 00:03:11,357
It's perfect.
29
00:03:12,842 --> 00:03:14,132
It's just perfect.
30
00:03:19,165 --> 00:03:22,295
Ferdinand Hayden tried to
survey this area in 1862.
31
00:03:25,538 --> 00:03:26,288
Planned it perfectly.
32
00:03:26,322 --> 00:03:29,082
You know, he came
out in the summer,
33
00:03:29,108 --> 00:03:31,738
but then a huge
storm in late June
34
00:03:31,778 --> 00:03:33,248
made the mountains impassable.
35
00:03:34,330 --> 00:03:37,120
Took him nine more years
to make it back here.
36
00:03:38,701 --> 00:03:40,121
It's a good thing he did.
37
00:03:45,541 --> 00:03:48,431
(upbeat majestic music)
38
00:03:59,339 --> 00:04:01,439
Yellowstone in the winter
is a thing of beauty.
39
00:04:14,187 --> 00:04:17,307
On an average year, 150
inches of snow will fall.
40
00:04:19,092 --> 00:04:22,262
And at higher elevations
it's often twice that.
41
00:04:24,163 --> 00:04:27,403
More than six months a
year it looks like this.
42
00:04:33,823 --> 00:04:35,683
Even the summer
months aren't safe
43
00:04:35,708 --> 00:04:37,208
from the occasional snowfall.
44
00:04:50,390 --> 00:04:53,360
In one of Yellowstone's most
spectacular winter sites
45
00:04:54,327 --> 00:04:56,147
diamond dust floats
through the air
46
00:04:56,179 --> 00:04:58,669
like a cloud of tiny mirrors.
47
00:04:58,698 --> 00:05:01,268
(light music)
48
00:05:06,205 --> 00:05:09,275
It gets so cold here that
water vapor crystallizes.
49
00:05:19,952 --> 00:05:21,352
It is both beautiful,
50
00:05:25,641 --> 00:05:26,431
and cruel.
51
00:05:35,601 --> 00:05:38,101
(bird quacks)
52
00:05:38,137 --> 00:05:41,167
Some will endure its challenges,
53
00:05:44,594 --> 00:05:48,284
while others seek out safe
havens in lower elevations.
54
00:05:51,417 --> 00:05:55,147
Some will burrow in dens
and wait out the season.
55
00:06:05,081 --> 00:06:06,831
While others thrive in a wild
56
00:06:06,866 --> 00:06:08,346
that has turned in their favor.
57
00:06:13,373 --> 00:06:15,343
(bird calls)
58
00:06:16,759 --> 00:06:18,179
But one thing is certain,
59
00:06:22,181 --> 00:06:24,421
in Yellowstone winner
cannot be ignored.
60
00:06:43,770 --> 00:06:45,690
The American bison
is the largest
61
00:06:45,721 --> 00:06:47,341
land mammal in North America.
62
00:06:50,943 --> 00:06:52,783
They've lived in
Yellowstone continuously
63
00:06:52,812 --> 00:06:54,482
since prehistoric times.
64
00:06:58,267 --> 00:07:00,147
You ever look at
a bison and wonder
65
00:07:00,186 --> 00:07:02,286
why they have those
massive humps?
66
00:07:04,307 --> 00:07:07,387
It's a perfectly
evolved adaptation to deal with the snow.
67
00:07:09,262 --> 00:07:12,012
Most ungulates forge
for grass by breaking up
68
00:07:12,048 --> 00:07:13,468
the snow with their hooves.
69
00:07:16,135 --> 00:07:18,195
That won't work
here in Yellowstone.
70
00:07:18,888 --> 00:07:21,388
The snow's too heavy, too deep.
71
00:07:23,075 --> 00:07:25,335
So the bison evolve massive
neck muscles that power
72
00:07:25,378 --> 00:07:28,348
their enormous head side
to side like a snowplow
73
00:07:29,732 --> 00:07:31,402
exposing the grass underneath.
74
00:07:32,768 --> 00:07:34,018
The temperature here can get
75
00:07:34,053 --> 00:07:37,193
as low as negative 60
degrees Fahrenheit.
76
00:07:38,141 --> 00:07:40,231
So it's good to
pack a heavy coat.
77
00:07:43,212 --> 00:07:46,472
The bison's is so heavy
that their body heat
78
00:07:46,499 --> 00:07:49,239
doesn't even melt the snow
that collects on their fur.
79
00:07:51,120 --> 00:07:53,070
Their skin thickens in winter
80
00:07:54,357 --> 00:07:57,207
and fatty deposits keep
them warm from the inside.
81
00:07:57,743 --> 00:08:00,333
(light music)
82
00:08:03,883 --> 00:08:06,793
But even the perfectly
adapted bison have
83
00:08:06,819 --> 00:08:08,389
to fight to survive
every winter.
84
00:08:14,610 --> 00:08:16,030
If it snows too much,
85
00:08:19,832 --> 00:08:21,282
they can't access the grass
86
00:08:21,317 --> 00:08:23,467
they need to fuel
their massive bodies.
87
00:08:41,103 --> 00:08:43,513
When the Hayden expedition
first came to Yellowstone
88
00:08:44,373 --> 00:08:46,533
they took note not only
of the largest herd
89
00:08:46,559 --> 00:08:51,199
that roamed the valleys,
but also the large number
90
00:08:51,230 --> 00:08:53,500
of dead bison that fed
the parks predators.
91
00:09:01,958 --> 00:09:03,778
Their left over after
the unrelenting winner
92
00:09:03,809 --> 00:09:05,209
culls the herd.
93
00:09:07,880 --> 00:09:09,670
The harsh conditions kill one
94
00:09:09,699 --> 00:09:11,349
out of 10 bison every year.
95
00:09:16,289 --> 00:09:21,329
This has become known
simply as winter kill.
96
00:09:24,547 --> 00:09:27,067
(bird calls)
97
00:09:34,957 --> 00:09:36,457
It provides
predators in the park
98
00:09:36,492 --> 00:09:40,012
with as much as 800,000
pounds of meat each winter.
99
00:09:45,568 --> 00:09:46,998
(dramatic music)
100
00:09:47,036 --> 00:09:49,266
Everyone wants a
piece of the action,
101
00:09:56,062 --> 00:09:58,402
because the window of
opportunity is small.
102
00:10:00,016 --> 00:10:02,496
The next snowstorm is
usually just hours away
103
00:10:02,535 --> 00:10:06,305
and anything left uneaten
will be buried until spring.
104
00:10:10,760 --> 00:10:13,380
(light music)
105
00:10:19,935 --> 00:10:22,165
Hoping to avoid that fate,
106
00:10:22,204 --> 00:10:24,674
these bison endure
long migration
107
00:10:24,707 --> 00:10:26,137
to lower elevations.
108
00:10:29,328 --> 00:10:31,858
Were super heated water
beneath the surface
109
00:10:31,897 --> 00:10:33,377
melts the snow above.
110
00:10:38,921 --> 00:10:40,241
There they will find the grass
111
00:10:40,272 --> 00:10:42,382
they need to survive
until spring.
112
00:10:50,082 --> 00:10:52,232
Every living thing
in Yellowstone spends
113
00:10:52,268 --> 00:10:55,448
at least half the year
battling the harsh conditions.
114
00:11:00,810 --> 00:11:02,230
It was something the pioneers
115
00:11:02,261 --> 00:11:05,901
on the Hayden Expedition
wanted to avoid dealing with,
116
00:11:05,931 --> 00:11:07,431
making their journey
in the summer.
117
00:11:11,687 --> 00:11:12,967
But they quickly found out
118
00:11:13,005 --> 00:11:14,785
that even the best laid plans
119
00:11:14,824 --> 00:11:16,384
can be undone quickly here.
120
00:11:19,862 --> 00:11:21,182
And so did I.
121
00:11:28,020 --> 00:11:31,320
You know, sometimes I
find myself wondering
122
00:11:32,675 --> 00:11:34,125
whose brilliant idea was this.
123
00:11:35,327 --> 00:11:39,117
Usually when that
happens, I'm the culprit.
124
00:11:39,148 --> 00:11:42,438
But man, Yellowstone
and the stone cold,
125
00:11:43,936 --> 00:11:45,536
it's no country for
the faint of heart.
126
00:11:47,907 --> 00:11:50,287
I mean, the animals
have had millions
127
00:11:50,326 --> 00:11:52,496
of years to adapt
to the conditions.
128
00:11:52,528 --> 00:11:56,078
And even still, there's
plenty that don't make it.
129
00:11:58,200 --> 00:12:00,390
Being here makes me
think about George Allen.
130
00:12:03,806 --> 00:12:05,606
One of the two
journals to survive
131
00:12:05,641 --> 00:12:07,241
through time was Allen's.
132
00:12:07,276 --> 00:12:10,376
He was a geologist
in Hayden's mentor.
133
00:12:10,413 --> 00:12:13,353
He was one of the older
gentlemen on the expedition.
134
00:12:14,700 --> 00:12:16,040
And sometime in the,
135
00:12:16,919 --> 00:12:19,559
sometime in late July in 1871,
136
00:12:19,588 --> 00:12:23,288
another big storm blew through
and it buried everything.
137
00:12:23,325 --> 00:12:26,195
And Alan was in
his tent shivering,
138
00:12:28,013 --> 00:12:29,833
kinda same way as
I am right now.
139
00:12:29,865 --> 00:12:31,075
And he wrote about,
140
00:12:32,084 --> 00:12:34,054
he wrote about how
miserable he was.
141
00:12:34,870 --> 00:12:37,140
Wasn't sure he'd
survived the expedition.
142
00:12:38,007 --> 00:12:39,487
He left the next day.
143
00:12:42,812 --> 00:12:44,232
That's probably a good decision.
144
00:12:46,766 --> 00:12:48,196
Probably a really good decision.
145
00:12:58,561 --> 00:13:02,011
Yellowstone National Park
is an easy place to visit,
146
00:13:03,032 --> 00:13:06,352
but living here, that's
anything but easy.
147
00:13:09,121 --> 00:13:11,241
Every species that
has managed to survive
148
00:13:11,273 --> 00:13:14,093
the winters has only done
so through adaptation.
149
00:13:17,413 --> 00:13:20,033
(light music)
150
00:13:34,196 --> 00:13:37,246
These river otters are perfectly
adapted to the conditions.
151
00:13:40,970 --> 00:13:43,460
Thick hair protects warm
skin from cold water.
152
00:13:50,379 --> 00:13:52,529
That's why their pelts
were so sought after
153
00:13:53,766 --> 00:13:55,016
by the hunters and trappers
154
00:13:55,050 --> 00:13:56,000
who made their way to
the Yellowstone region
155
00:13:56,035 --> 00:13:58,065
long before Hayden and his men.
156
00:14:01,991 --> 00:14:03,981
The otter furs
were in high demand
157
00:14:04,009 --> 00:14:06,779
by the wealthiest
people back east,
158
00:14:06,812 --> 00:14:07,932
because of the
warmth they provided
159
00:14:07,963 --> 00:14:10,123
and the luster of the fur.
160
00:14:12,968 --> 00:14:14,868
Today, the otters in Yellowstone
161
00:14:14,904 --> 00:14:16,464
don't have to worry
about trappers.
162
00:14:18,841 --> 00:14:20,731
Their battle is
keeping themselves fed
163
00:14:20,759 --> 00:14:22,179
during the cold winter months.
164
00:14:28,751 --> 00:14:29,591
The steady supply of fish
165
00:14:29,618 --> 00:14:33,258
and open water can only be
counted on in the warmer months.
166
00:14:39,912 --> 00:14:41,482
The winter freeze
chokes off the river,
167
00:14:43,265 --> 00:14:46,285
cutting off the food supply for
the mother and her two pups.
168
00:14:58,180 --> 00:15:00,520
They go from one hole
in the ice to another
169
00:15:00,549 --> 00:15:01,979
in search of a meal.
170
00:15:09,058 --> 00:15:11,738
But with every fish they
pull from the icy depths,
171
00:15:11,777 --> 00:15:13,147
the supplies lessened.
172
00:15:14,313 --> 00:15:17,433
And soon this family will need
to find a new place to fish.
173
00:15:20,019 --> 00:15:22,269
River otters may reign
supreme in water,
174
00:15:22,304 --> 00:15:25,194
but on land it's a
different story together.
175
00:15:26,175 --> 00:15:29,295
Here they go from
hunter to hunted.
176
00:15:32,031 --> 00:15:33,881
Alternating between
hopping and sliding,
177
00:15:33,916 --> 00:15:35,366
they can reach speeds
178
00:15:35,401 --> 00:15:38,201
of 15 miles per hour
through the heavy snow.
179
00:15:43,726 --> 00:15:45,906
They'll need that speed
180
00:15:45,945 --> 00:15:47,475
as they search for
a new fishing hole.
181
00:15:49,064 --> 00:15:51,054
And predators are abound.
182
00:16:01,260 --> 00:16:04,830
While the otter family struggles
against the cold and snow,
183
00:16:04,863 --> 00:16:06,273
wolfs thrive.
184
00:16:14,707 --> 00:16:17,177
(wolf calls)
185
00:16:18,143 --> 00:16:21,153
In these conditions,
they're top dog.
186
00:16:30,906 --> 00:16:33,126
But winter brings
territorial disputes,
187
00:16:33,976 --> 00:16:37,046
and at times unbridled savagery.
188
00:16:40,983 --> 00:16:43,193
This is when strong packs expand
189
00:16:44,953 --> 00:16:47,113
and weak packs die off.
190
00:16:48,490 --> 00:16:51,330
The druid pack once rained
supreme in this area,
191
00:16:52,011 --> 00:16:54,181
only to wither in recent years
192
00:16:54,213 --> 00:16:56,353
as Molly's pack has
taken the throne.
193
00:16:58,133 --> 00:17:01,173
But with success comes problems
194
00:17:01,203 --> 00:17:04,223
and Molly's pack already
finds itself in turmoil.
195
00:17:09,595 --> 00:17:13,245
Rival packs are constantly on
the lookout for new territory.
196
00:17:15,084 --> 00:17:18,224
Recently a pack of 15 wolves
traveled 40 miles outside
197
00:17:18,253 --> 00:17:21,143
of their territory to
take on another pack.
198
00:17:22,207 --> 00:17:25,177
Securing territory is
key to their survival.
199
00:17:26,145 --> 00:17:28,195
More land means more
hunting grounds.
200
00:17:29,431 --> 00:17:32,151
(dramatic music)
201
00:17:46,415 --> 00:17:51,345
In winter, elk is the main
thing on the menu for this pack.
202
00:17:56,041 --> 00:17:59,091
90% of their diet is elk
during this cold period.
203
00:18:03,132 --> 00:18:05,352
An elk cow has been
separated from the harem.
204
00:18:08,070 --> 00:18:10,320
And even with
strength in numbers
205
00:18:10,355 --> 00:18:14,155
fighting off a wolf
pack is a hero's task.
206
00:18:17,012 --> 00:18:19,002
The wolves move
on to high ground
207
00:18:20,182 --> 00:18:24,292
and when the sun goes
down, they will strike.
208
00:18:26,038 --> 00:18:29,168
When they do, they'll
announce it to the world.
209
00:18:36,482 --> 00:18:39,082
(wolf calls)
210
00:18:42,771 --> 00:18:45,261
(bird calls)
211
00:18:52,881 --> 00:18:54,081
The wolf's ability to hunt
212
00:18:54,116 --> 00:18:56,736
elk doesn't just
keep them well fed.
213
00:18:56,768 --> 00:18:58,398
It keeps the park in balance.
214
00:19:00,088 --> 00:19:02,268
By thinning out
oversized elk populations
215
00:19:02,307 --> 00:19:05,337
and cutting down the
weak and sick among them
216
00:19:05,377 --> 00:19:09,107
they leave stronger, more
resilient elk herds behind.
217
00:19:11,049 --> 00:19:13,149
The elk cow has
made a good meal,
218
00:19:14,520 --> 00:19:15,300
but it's not enough.
219
00:19:16,505 --> 00:19:17,365
It's never enough.
220
00:19:20,108 --> 00:19:22,328
These wolves need more
calories in the winter.
221
00:19:24,963 --> 00:19:26,353
Moving through heavy snow
222
00:19:26,381 --> 00:19:29,201
and maintaining body heat
requires more energy.
223
00:19:31,770 --> 00:19:33,310
So they're on the
prowl for more,
224
00:19:34,606 --> 00:19:36,036
and always will be.
225
00:19:37,259 --> 00:19:41,459
Like I said, it's an
easy place to visit,
226
00:19:41,496 --> 00:19:42,306
tough place to live.
227
00:19:47,052 --> 00:19:49,122
This male bobcat
is another creature
228
00:19:49,154 --> 00:19:51,324
that will fight to
survive all winter long.
229
00:19:54,026 --> 00:19:55,426
Every meal will be a battle.
230
00:20:00,983 --> 00:20:03,403
A duck, now that's good eating.
231
00:20:05,370 --> 00:20:08,160
It could keep him
fed for several days.
232
00:20:12,211 --> 00:20:15,211
He typically prowls the
conifer forest of Yellowstone.
233
00:20:16,148 --> 00:20:18,968
But desperate times call
for desperate measures.
234
00:20:19,001 --> 00:20:20,421
And he comes into
the open today.
235
00:20:24,006 --> 00:20:25,916
His small feet and short legs
236
00:20:25,958 --> 00:20:27,428
aren't built for the loose snow.
237
00:20:30,679 --> 00:20:32,149
And despite his appetite
238
00:20:32,180 --> 00:20:34,430
he's hesitant to get
into the cold water.
239
00:20:40,055 --> 00:20:41,935
Though the bobcat
is a skilled hunter
240
00:20:41,974 --> 00:20:43,344
this isn't a fair fight.
241
00:20:44,626 --> 00:20:45,476
He's out of his element.
242
00:20:51,566 --> 00:20:55,146
Finding meals will only get
harder as winter continues
243
00:20:55,187 --> 00:20:57,467
and fat stores and
energy reserves dwindle.
244
00:21:02,160 --> 00:21:04,250
And if the bobcat
is going to feed,
245
00:21:05,714 --> 00:21:08,134
all he can do is buy his time
246
00:21:08,166 --> 00:21:10,166
and wait for the
right opportunity.
247
00:21:24,666 --> 00:21:27,386
(dramatic music)
248
00:21:50,776 --> 00:21:52,406
As lovely as the sight is,
249
00:21:54,179 --> 00:21:56,349
as lucid and clean
the fallen snow,
250
00:21:58,800 --> 00:22:00,150
I can't help but think
251
00:22:00,185 --> 00:22:02,185
of the chaos that
winter brings with it.
252
00:22:05,941 --> 00:22:07,331
Ever been to a bonfire?
253
00:22:08,810 --> 00:22:10,250
You know, that's how when you
254
00:22:10,278 --> 00:22:12,178
first show up people
are all spread out.
255
00:22:12,214 --> 00:22:13,824
Maybe there's a
few around the fire
256
00:22:13,849 --> 00:22:16,179
but you got some
people over here
257
00:22:16,218 --> 00:22:18,298
and you got another
group over there.
258
00:22:20,088 --> 00:22:23,238
Then it gets late
and night grows cold.
259
00:22:23,275 --> 00:22:24,925
Eventually, every last
person that's huddled
260
00:22:24,960 --> 00:22:26,280
around that fire.
261
00:22:31,466 --> 00:22:32,226
That down there,
262
00:22:33,952 --> 00:22:35,252
that's a bonfire.
263
00:22:41,910 --> 00:22:43,410
When it gets warmer
264
00:22:43,445 --> 00:22:45,305
the animals spread out
and make their way up
265
00:22:45,347 --> 00:22:47,527
the ranges all the
way to the peaks.
266
00:22:48,850 --> 00:22:50,300
Then when the snow comes,
267
00:22:51,470 --> 00:22:54,870
they head back down to
the Valley seeking refuge,
268
00:22:54,906 --> 00:22:56,386
creatures that have absolutely
269
00:22:56,425 --> 00:22:59,305
no interest in being friends
huddle around that fire.
270
00:23:01,863 --> 00:23:04,303
When it gets 30, 40
degrees below zero
271
00:23:04,332 --> 00:23:08,172
that fire dims and they
huddle even closer.
272
00:23:09,838 --> 00:23:11,318
That's when all
hell breaks loose.
273
00:23:12,858 --> 00:23:15,428
(dramatic music)
274
00:23:21,733 --> 00:23:24,343
(wolf calls)
275
00:23:27,923 --> 00:23:29,463
The large herds that
graze the valleys
276
00:23:29,491 --> 00:23:32,991
in spring and summer have
broken into smaller groups
277
00:23:33,028 --> 00:23:35,398
as they migrate toward
the lower elevations.
278
00:23:41,770 --> 00:23:43,290
And no one is more aware of this
279
00:23:43,321 --> 00:23:45,271
than the wolves who
track these smaller herds
280
00:23:45,307 --> 00:23:47,427
as they migrate
towards the bonfire.
281
00:24:08,597 --> 00:24:11,317
(dramatic music)
282
00:24:18,106 --> 00:24:20,026
These bison have
traveled 40 miles
283
00:24:20,058 --> 00:24:21,488
to reach the geyser basin.
284
00:24:33,939 --> 00:24:37,509
For a migration that
began weeks ago.
285
00:24:37,542 --> 00:24:40,412
The steam from the thermal
vents is a welcome site,
286
00:24:46,368 --> 00:24:49,298
but the warmth of the thermals
draws in predator and prey.
287
00:24:54,809 --> 00:24:57,429
(light music)
288
00:25:02,050 --> 00:25:05,440
The bison herd arrives
at the geyser basin.
289
00:25:16,264 --> 00:25:18,784
The super volcano beneath
the Earth's surface fights
290
00:25:18,817 --> 00:25:20,217
against the cold above,
291
00:25:23,705 --> 00:25:25,305
sending steam outward,
292
00:25:25,340 --> 00:25:28,260
melting the snow and
exposing the grass.
293
00:25:31,863 --> 00:25:34,073
But there is a downside
to grazing here.
294
00:25:36,318 --> 00:25:39,438
The grass that grows near the
thermal has less nutrients
295
00:25:42,991 --> 00:25:45,581
and the long journey
to get here took a lot
296
00:25:45,610 --> 00:25:46,380
out of the bison.
297
00:25:52,867 --> 00:25:54,847
By the time they arrive
298
00:25:54,886 --> 00:25:56,316
they're at their weakest.
299
00:26:03,678 --> 00:26:05,228
And wolves are opportunists.
300
00:26:09,884 --> 00:26:11,494
They've traveled across
the park to greet
301
00:26:11,519 --> 00:26:16,309
the bison at the bonfire, just
like they do every winter.
302
00:26:22,280 --> 00:26:24,830
Taking on a herd of healthy
bison at full strength
303
00:26:24,866 --> 00:26:26,316
isn't worth the effort,
304
00:26:31,289 --> 00:26:33,279
but in their tired,
weakened state,
305
00:26:36,611 --> 00:26:37,361
the wolves will come.
306
00:26:43,285 --> 00:26:45,465
With the sun setting,
the attack is imminent.
307
00:26:46,688 --> 00:26:49,418
(dramatic music)
308
00:26:59,951 --> 00:27:03,121
Under the cover of
darkness they strike,
309
00:27:12,981 --> 00:27:15,071
and by the time the sun rises,
310
00:27:18,820 --> 00:27:20,340
the wolves are
finishing their meal.
311
00:27:31,666 --> 00:27:32,976
They'll eat as much as 20 pounds
312
00:27:33,018 --> 00:27:35,148
of meat each on
a kill like this.
313
00:27:47,882 --> 00:27:49,432
With their bellies full,
314
00:27:49,467 --> 00:27:52,037
the wolves will leave the
bison herd alone today.
315
00:27:58,993 --> 00:28:01,013
Tonight will be a
different story.
316
00:28:04,366 --> 00:28:07,066
(dramatic music)
317
00:28:13,775 --> 00:28:15,225
Back at the riverbank,
318
00:28:15,260 --> 00:28:18,330
the starving bobcat continues
his fight for survival.
319
00:28:23,685 --> 00:28:26,365
He needs a meal, and soon.
320
00:28:28,306 --> 00:28:31,736
A musk rat may not
taste as good as a duck,
321
00:28:31,776 --> 00:28:33,076
but it'll have to do.
322
00:28:34,345 --> 00:28:36,815
The semi-aquatic musk
rat builds his burrow
323
00:28:36,848 --> 00:28:38,078
on the river bank.
324
00:28:41,136 --> 00:28:46,166
Little does he know
he's being hunted.
325
00:28:51,679 --> 00:28:53,129
The bobcat was reluctant to jump
326
00:28:53,164 --> 00:28:55,374
into the freezing water
to catch the duck,
327
00:28:57,685 --> 00:28:59,045
but he's one day hungrier.
328
00:28:59,921 --> 00:29:01,391
One day more desperate.
329
00:29:29,017 --> 00:29:31,417
Another meal has slipped away.
330
00:29:33,188 --> 00:29:36,008
It's going to be a long
winter for the bobcat.
331
00:29:38,092 --> 00:29:42,382
If his luck doesn't change
soon, it may be a short one.
332
00:29:42,413 --> 00:29:45,133
(dramatic music)
333
00:29:54,876 --> 00:29:57,126
At the higher elevations,
334
00:29:58,913 --> 00:30:00,803
Yellowstone's big
horn sheep fight
335
00:30:00,832 --> 00:30:02,202
their own battle every winter.
336
00:30:14,045 --> 00:30:15,955
The big horn sheep in
Yellowstone descend
337
00:30:15,997 --> 00:30:18,127
from sheep that left Siberia
338
00:30:18,166 --> 00:30:20,866
and migrated across
the Bering land bridge.
339
00:30:20,902 --> 00:30:23,052
750,000 years ago,
340
00:30:26,741 --> 00:30:28,091
they became the primary source
341
00:30:28,126 --> 00:30:31,156
of food for the
indigenous Tukudika tribe
342
00:30:31,196 --> 00:30:33,826
who lived in Yellowstone
thousands of years
343
00:30:33,865 --> 00:30:35,495
before Hayden ever
set foot there.
344
00:30:39,971 --> 00:30:42,741
Tukudika is roughly
translated to eaters
345
00:30:42,774 --> 00:30:44,084
of the mountain sheep,
346
00:30:46,961 --> 00:30:48,931
and the tribes lived
at high elevations
347
00:30:48,963 --> 00:30:50,453
where the big horn
was plentiful.
348
00:30:52,967 --> 00:30:55,297
They used the sheep
not only for food,
349
00:30:55,336 --> 00:30:58,456
but by warming their horns in
Yellowstone's thermal waters,
350
00:31:00,158 --> 00:31:02,228
they could shape them into
extremely durable bows.
351
00:31:05,046 --> 00:31:06,876
There used to be millions
of big horns spread
352
00:31:06,915 --> 00:31:09,025
across the Western
United States,
353
00:31:11,085 --> 00:31:14,105
today there are
fewer than 70,000.
354
00:31:15,974 --> 00:31:19,114
And each winter,
Yellowstone's big horn
355
00:31:19,143 --> 00:31:23,183
decide who gets to mate
this year and who doesn't.
356
00:31:25,817 --> 00:31:27,247
Through a series of battles,
357
00:31:28,219 --> 00:31:30,519
toughest males
established dominance,
358
00:31:35,927 --> 00:31:38,057
only they will have
breeding rights.
359
00:31:38,713 --> 00:31:41,433
(dramatic music)
360
00:31:44,068 --> 00:31:47,088
A fully grown ram
can weigh 300 pounds,
361
00:31:48,039 --> 00:31:50,279
40 of which are
held in their horns.
362
00:31:51,960 --> 00:31:54,180
Their skulls have two
layers of cushion above
363
00:31:54,212 --> 00:31:57,282
the brain which absorb the
impact of the collision.
364
00:32:05,023 --> 00:32:06,823
The sounds of winter
are almost as incredible
365
00:32:06,858 --> 00:32:08,188
as the sights.
366
00:32:15,750 --> 00:32:17,440
Almost is incredible.
367
00:32:21,539 --> 00:32:25,079
There's something majestic
about the snow covered peaks.
368
00:32:29,514 --> 00:32:32,324
Something inspiring about
seeing the wild world.
369
00:32:36,838 --> 00:32:38,518
Unchanged by the hands of man.
370
00:32:40,975 --> 00:32:42,525
Unchanged by the hands of time.
371
00:32:47,765 --> 00:32:50,265
(bird calls)
372
00:32:57,558 --> 00:32:59,938
I don't think I'm any
different than anyone else.
373
00:32:59,978 --> 00:33:01,598
We all grew up in
different places.
374
00:33:01,629 --> 00:33:03,099
I grew up in the inner city.
375
00:33:03,131 --> 00:33:05,221
I was born in a place
called Compton, California.
376
00:33:07,301 --> 00:33:09,791
But I remember when I
got my first glimpse
377
00:33:09,821 --> 00:33:12,191
of the Rocky Mountains.
378
00:33:15,126 --> 00:33:17,376
You know, it was like the
scales came off my eyes
379
00:33:17,412 --> 00:33:21,072
and I thought could there be a
place like this in the world?
380
00:33:26,170 --> 00:33:28,890
The reality is that
America's so big,
381
00:33:28,923 --> 00:33:31,043
and Yellowstone reminds you
382
00:33:31,075 --> 00:33:33,225
of what the country
might have looked
383
00:33:33,261 --> 00:33:36,151
like before there was any
outsiders that ever came,
384
00:33:37,265 --> 00:33:39,515
and to know that the
rivers still flow
385
00:33:40,818 --> 00:33:42,248
and these mountains still stand.
386
00:33:46,140 --> 00:33:49,360
There is something that
we should be thankful for,
387
00:33:50,962 --> 00:33:53,952
the human will to
convince other people
388
00:33:53,981 --> 00:33:55,531
that this is worth keeping.
389
00:33:58,002 --> 00:34:00,242
It wasn't a battle
and it was uphill
390
00:34:02,073 --> 00:34:05,133
but it was about one
man who believed he had
391
00:34:05,159 --> 00:34:09,199
an idea about himself,
so much so that he knew
392
00:34:09,230 --> 00:34:12,370
if given the chance he
could change the world.
393
00:34:12,400 --> 00:34:15,000
(light music)
394
00:34:17,338 --> 00:34:20,828
Ferdinand Hayden's
determination to convince the US
395
00:34:20,858 --> 00:34:22,878
Congress to protect Yellowstone
396
00:34:22,910 --> 00:34:25,080
rather than let it
be torn apart is
397
00:34:25,113 --> 00:34:27,233
the reason we can tell
these stories today.
398
00:34:28,299 --> 00:34:32,269
It's the reason that
the bobcats and bison,
399
00:34:35,139 --> 00:34:38,909
and wolves have this
pristine landscape to roam,
400
00:34:38,943 --> 00:34:43,113
to breed, to fight,
and to survive.
401
00:34:44,532 --> 00:34:47,152
(wolf calls)
402
00:34:49,036 --> 00:34:51,236
Survival is the name
of the game in winter.
403
00:34:57,028 --> 00:34:59,008
The river otters continue
their desperate trek
404
00:34:59,046 --> 00:35:01,126
to find a new food source.
405
00:35:04,786 --> 00:35:06,046
They've made their way
406
00:35:06,087 --> 00:35:08,137
to a place where the
water never freezes.
407
00:35:11,776 --> 00:35:13,036
The upper falls.
408
00:35:17,081 --> 00:35:20,051
Water crashing from the
falls churns the pool below,
409
00:35:21,018 --> 00:35:23,018
preventing it from freezing.
410
00:35:29,110 --> 00:35:32,060
But the fishing hole
is 109 feet down.
411
00:35:39,887 --> 00:35:42,067
In the summer of 1871,
412
00:35:43,374 --> 00:35:45,694
Hayden and his men used
ropes to traverse the falls
413
00:35:45,726 --> 00:35:47,246
as they explored Yellowstone.
414
00:35:51,449 --> 00:35:54,389
Believe it or not, these
otters don't have any ropes.
415
00:36:01,292 --> 00:36:04,102
But the snow creates
another opportunity.
416
00:36:04,745 --> 00:36:07,265
(light music)
417
00:36:13,104 --> 00:36:15,414
Mom teaches the pups
the art of sledding.
418
00:36:28,502 --> 00:36:31,392
(light music continues)
419
00:36:44,252 --> 00:36:47,072
The otter family makes it
to their new fishing hole.
420
00:36:51,309 --> 00:36:56,279
They're back in their
element, and soon they'll die.
421
00:37:09,176 --> 00:37:12,026
They found a workaround
for the winter conditions
422
00:37:12,063 --> 00:37:14,103
and food here will be abundant.
423
00:37:43,594 --> 00:37:46,204
(bird calls)
424
00:37:48,649 --> 00:37:50,299
The bobcat isn't so lucky,
425
00:38:04,248 --> 00:38:06,378
the pangs of hunger
are overwhelming
426
00:38:08,269 --> 00:38:10,449
and he is in desperate
search of food.
427
00:38:11,789 --> 00:38:14,389
(dramatic music)
428
00:38:29,123 --> 00:38:31,313
At this point, he'll
settle for anything.
429
00:38:40,618 --> 00:38:41,488
It's all or nothing.
430
00:38:45,706 --> 00:38:47,286
The time to strike is now.
431
00:39:21,809 --> 00:39:24,229
Finally, the bobcat
has his dinner.
432
00:39:32,186 --> 00:39:33,966
His chances of
surviving the winter
433
00:39:34,004 --> 00:39:35,444
just got a little better.
434
00:39:47,068 --> 00:39:49,368
Yellowstone in winter is iconic.
435
00:39:54,508 --> 00:39:55,458
A world of ice,
436
00:39:58,579 --> 00:39:59,359
and fire.
437
00:40:05,035 --> 00:40:06,295
A world where every creature
438
00:40:06,337 --> 00:40:09,017
fights their own battle
every single day.
439
00:40:15,413 --> 00:40:17,423
(wolf calls)
440
00:40:20,184 --> 00:40:22,254
But if not for the
pioneers who made
441
00:40:22,286 --> 00:40:25,336
the decision to protect
this place 150 years ago,
442
00:40:27,875 --> 00:40:29,485
we'd never know that
it even existed.
443
00:40:41,806 --> 00:40:43,386
You know, I don't know
444
00:40:43,424 --> 00:40:45,214
if there's another place
on Earth that gives you
445
00:40:45,242 --> 00:40:47,112
the evocative
spectacle of nature
446
00:40:47,144 --> 00:40:48,554
that Yellowstone
does in the snow.
447
00:40:51,132 --> 00:40:53,252
And being here,
seeing it firsthand,
448
00:40:54,752 --> 00:40:56,302
makes me wonder what if,
449
00:40:57,455 --> 00:41:00,455
what if Hayden and his
team never came here?
450
00:41:02,176 --> 00:41:03,836
What if they'd
been delayed a year
451
00:41:03,878 --> 00:41:06,208
and people had
set up gold mines?
452
00:41:10,267 --> 00:41:13,497
What if their plan to protect
this place didn't work?
453
00:41:14,972 --> 00:41:16,472
And the truth was,
it almost didn't.
454
00:41:18,209 --> 00:41:20,479
There was a photographer
named Anton Sean Burn.
455
00:41:25,065 --> 00:41:26,225
He was part of the expedition
456
00:41:26,267 --> 00:41:28,517
and he was a big part
of Hayden's plan.
457
00:41:30,037 --> 00:41:32,017
He took all the notes
they were gonna use
458
00:41:32,056 --> 00:41:34,376
to create the maps that
they were gonna present
459
00:41:34,408 --> 00:41:38,778
to Congress and those
maps were gonna be crucial
460
00:41:38,812 --> 00:41:40,302
in getting
Yellowstone protected,
461
00:41:41,298 --> 00:41:43,318
then just days before
he was gonna meet,
462
00:41:44,468 --> 00:41:48,438
meet Hayden in Washington
DC, he killed himself.
463
00:41:49,840 --> 00:41:51,910
Turns out that six days earlier
464
00:41:51,942 --> 00:41:54,632
the great Chicago
fire had destroyed
465
00:41:54,662 --> 00:41:58,082
a huge amount of the data
collected on the expedition.
466
00:41:59,867 --> 00:42:00,967
It was tragic, of course,
467
00:42:01,001 --> 00:42:04,691
but it was a
disaster for Hayden,
468
00:42:04,722 --> 00:42:06,262
and he needed to act fast.
469
00:42:09,260 --> 00:42:12,100
Hayden knew that a watershed
moment was upon him.
470
00:42:13,214 --> 00:42:15,274
He knew that the wolves
were at the gates
471
00:42:15,299 --> 00:42:18,319
and the snow was the only
thing keeping them out.
472
00:42:20,588 --> 00:42:22,288
For when spring arrived,
473
00:42:22,323 --> 00:42:25,093
the destruction of Yellowstone
would begin in force.
474
00:42:34,184 --> 00:42:36,454
The vandals who are waiting
to enter this wonderland
475
00:42:36,487 --> 00:42:39,757
will in a single season
be spoiled beyond recovery
476
00:42:39,790 --> 00:42:41,490
these remarkable curiosities,
477
00:42:43,010 --> 00:42:44,430
which have required
all the cunning skill
478
00:42:44,461 --> 00:42:47,281
of nature of thousands
of years to prepare.
479
00:42:52,286 --> 00:42:55,356
With that said, Hayden
cast the first stone
480
00:42:55,389 --> 00:42:57,509
to protect the land
that he'd grown to love.
481
00:43:14,275 --> 00:43:16,005
You know, Hayden
predicted they would come
482
00:43:16,043 --> 00:43:19,883
in droves to destroy this
place once the winter
483
00:43:19,913 --> 00:43:21,433
released the land
from its clutches.
484
00:43:22,349 --> 00:43:26,769
His words, not mine,
but boy was he right.
485
00:43:26,804 --> 00:43:30,274
Spring finally came in 1872,
486
00:43:31,692 --> 00:43:33,342
and one after another,
487
00:43:33,377 --> 00:43:35,877
the profiteers started
filing their claims,
488
00:43:35,913 --> 00:43:38,423
100, 150, 200 acres at a time.
489
00:43:40,000 --> 00:43:42,170
The claims poured into
the public land office.
490
00:43:43,304 --> 00:43:47,324
Everything from gold to silver
to medicinal spring water.
491
00:43:47,358 --> 00:43:51,058
Every damn thing we've seen
had a claim filed on it.
492
00:43:52,946 --> 00:43:54,426
And the miracle of it all was
493
00:43:54,465 --> 00:43:58,315
that every single claim
that was filed that year,
494
00:43:59,803 --> 00:44:01,293
every single one was denied.
495
00:44:05,893 --> 00:44:07,463
Because you see,
eight days earlier,
496
00:44:07,494 --> 00:44:11,434
President Ulysses S. Grant
signed Hayden's bill into law.
497
00:44:12,983 --> 00:44:14,923
The National Park
system was created
498
00:44:14,952 --> 00:44:17,152
just in the nick of time,
499
00:44:18,255 --> 00:44:22,025
and Yellowstone was
saved by eight days.
500
00:44:24,728 --> 00:44:25,858
You know, that's
not a fairytale.
501
00:44:25,896 --> 00:44:28,946
It's not a Hollywood ending,
502
00:44:28,982 --> 00:44:31,042
it's just how close
it all was to going.
503
00:44:32,553 --> 00:44:35,473
No one alive today would even
know this land even existed.
504
00:44:39,143 --> 00:44:40,513
Thank God for that snow, huh?
505
00:44:41,645 --> 00:44:44,155
(light music)
506
00:44:49,870 --> 00:45:00,030
- Let's go, pal.
507
