1
00:00:12,846 --> 00:00:15,056
Welcome to North America.
2
00:00:21,187 --> 00:00:23,815
The most diverse
continent on Earth.
3
00:00:27,485 --> 00:00:31,823
The only place where you can find
every landscape from polar ice cap...
4
00:00:33,742 --> 00:00:37,662
to baking desert, and
everything in between.
5
00:00:39,956 --> 00:00:44,669
Whatever the neighborhood, there's
a hero who can make it a home.
6
00:00:51,426 --> 00:00:56,765
Smart, tough,
brave, you name it.
7
00:00:57,599 --> 00:01:00,018
They all have what
it takes to thrive
8
00:01:00,935 --> 00:01:04,564
in the wildest, most
beautiful continent on Earth.
9
00:01:07,067 --> 00:01:11,029
Patchwork quilt of life
10
00:01:12,155 --> 00:01:17,452
Wildness never dies
11
00:01:17,577 --> 00:01:22,207
Beauty always thrives
12
00:01:22,832 --> 00:01:28,546
Under these spacious skies
13
00:01:43,228 --> 00:01:47,482
Every corner of America calls
for a different kind of hero.
14
00:01:49,484 --> 00:01:52,112
These are the Teton
Mountains of Wyoming.
15
00:01:52,362 --> 00:01:55,949
The edge of North America's biggest
mountain range, the Rockies.
16
00:01:59,869 --> 00:02:03,832
With towering peaks
and vast forests,
17
00:02:05,542 --> 00:02:07,919
this is a land of giants.
18
00:02:10,004 --> 00:02:13,299
But heroes come in
all shapes and sizes.
19
00:02:18,972 --> 00:02:20,306
A red squirrel.
20
00:02:22,183 --> 00:02:26,938
Yeah, he's small, but trust
me, size isn't everything.
21
00:02:29,399 --> 00:02:31,484
He's collecting pinecone seeds
22
00:02:31,568 --> 00:02:34,529
to help feed him through the
long mountain winter ahead.
23
00:02:41,911 --> 00:02:44,664
He's been hard at
work for two months.
24
00:02:47,667 --> 00:02:50,128
And he's collected a
stash to be proud of.
25
00:02:56,843 --> 00:03:00,972
With all those savings in the bank,
you might think he could rest easy.
26
00:03:05,518 --> 00:03:07,061
But life's not that simple.
27
00:03:13,026 --> 00:03:15,028
A freeloading black bear.
28
00:03:18,114 --> 00:03:19,115
Darn!
29
00:03:22,202 --> 00:03:24,579
He's not gonna take
this lying down.
30
00:03:30,668 --> 00:03:31,794
What the...
31
00:03:34,505 --> 00:03:36,257
Seriously?
32
00:03:38,593 --> 00:03:40,887
I mean, you got to admire
the squirrel's guts.
33
00:03:41,429 --> 00:03:44,098
He's taking on a guy a
thousand times his size.
34
00:03:52,941 --> 00:03:56,861
If he gets too close, he might
end up in a pinecone sandwich.
35
00:04:04,327 --> 00:04:05,954
He tries the angry holler.
36
00:04:07,497 --> 00:04:08,581
The blitz defense.
37
00:04:11,751 --> 00:04:13,544
But dream on.
38
00:04:16,547 --> 00:04:19,259
The whole stash is
gone in minutes.
39
00:04:23,137 --> 00:04:24,847
A small snack for the thief,
40
00:04:26,724 --> 00:04:28,726
a big problem for the squirrel.
41
00:04:39,529 --> 00:04:40,863
He's not defeated, though.
42
00:04:46,494 --> 00:04:48,621
He finds some new hiding spots.
43
00:04:52,834 --> 00:04:57,046
As evening falls, he's
still hard at work.
44
00:04:59,507 --> 00:05:02,260
And yet more strangers
show up on his patch.
45
00:05:04,095 --> 00:05:05,596
Long-eared owls.
46
00:05:06,723 --> 00:05:08,599
They like to dine
out on squirrels.
47
00:05:15,273 --> 00:05:17,817
Probably a good
time to head to bed.
48
00:05:20,611 --> 00:05:24,699
While he's sleeping, his
worst nightmare comes true.
49
00:05:27,035 --> 00:05:29,912
Porcupines uncover one
of his new stashes.
50
00:05:35,835 --> 00:05:40,923
And worse still, a grizzly bear,
the greediest thief of them all,
51
00:05:42,425 --> 00:05:44,886
finds the last of
his buried savings.
52
00:06:03,029 --> 00:06:04,655
Morning brings a scene of...
53
00:06:05,698 --> 00:06:06,866
carnage.
54
00:06:20,922 --> 00:06:22,799
All appears lost.
55
00:06:27,387 --> 00:06:30,056
But here's why this
squirrel's a hero.
56
00:06:35,269 --> 00:06:39,148
Up in a treetop, he's been
gathering a secret supply
57
00:06:39,315 --> 00:06:41,359
that the big guys didn't find.
58
00:06:43,444 --> 00:06:46,030
He didn't put all his
eggs in one basket.
59
00:06:52,787 --> 00:06:53,955
Smart thinking,
60
00:06:54,705 --> 00:06:58,042
just what you need to make it
in the mountains of America.
61
00:07:05,758 --> 00:07:08,719
Mountain worlds cover one
quarter of our continent.
62
00:07:10,346 --> 00:07:13,975
From the glacier-carved Yosemite
Valley in the Sierra Nevada...
63
00:07:20,356 --> 00:07:24,193
to the volcanoes of the
Cascades and Aleutians.
64
00:07:26,696 --> 00:07:31,576
Most famous of our 300 active
volcanoes is Mount St. Helens.
65
00:07:38,624 --> 00:07:40,585
And the highest point
in the continent?
66
00:07:41,294 --> 00:07:46,090
Over 20,000 feet.
Denali, in Alaska.
67
00:07:51,137 --> 00:07:55,349
Up high, the extreme cold is
the biggest challenge for life.
68
00:07:59,061 --> 00:08:00,646
Drop down to the coast,
69
00:08:00,938 --> 00:08:03,900
and there's a whole different
set of problems to overcome.
70
00:08:06,903 --> 00:08:12,366
In the South, thousands of square miles
of wetlands sit just above sea level,
71
00:08:12,909 --> 00:08:16,120
including the biggest swamp
in all of North America.
72
00:08:19,248 --> 00:08:21,959
The Atchafalaya in Louisiana.
73
00:08:29,467 --> 00:08:31,552
It's ruled over by a giant
74
00:08:31,677 --> 00:08:34,263
that's been around since
the time of the dinosaurs.
75
00:08:48,653 --> 00:08:52,281
An American alligator,
our biggest reptile.
76
00:08:53,282 --> 00:08:56,702
Up to 15 feet long,
and a half a ton.
77
00:09:03,543 --> 00:09:05,336
How has her kind survived
78
00:09:05,419 --> 00:09:08,214
in America's wetlands
for 70 million years?
79
00:09:13,094 --> 00:09:14,262
Patience.
80
00:09:15,513 --> 00:09:19,141
She'll wait as long as it
takes to catch her prey.
81
00:09:25,147 --> 00:09:28,985
It helps that she can go
for two years between meals.
82
00:09:32,947 --> 00:09:35,700
Eyes and nostrils on
the top of her head
83
00:09:36,075 --> 00:09:40,037
mean that she can stay hidden
underwater while she looks for food.
84
00:09:43,749 --> 00:09:45,668
She'll eat just about anything.
85
00:10:01,601 --> 00:10:06,147
Although today, she's
gunning for a big prize.
86
00:10:11,319 --> 00:10:12,987
A white-tailed deer.
87
00:10:25,291 --> 00:10:28,836
The best grazing is right
by the water's edge.
88
00:10:34,967 --> 00:10:40,097
The younger deer have no experience
of the danger that can lie beneath.
89
00:11:03,663 --> 00:11:06,749
She has to keep it real slow.
90
00:11:22,932 --> 00:11:25,559
These guys are too wary.
91
00:11:28,896 --> 00:11:32,692
Maybe a resting deer will
be easier to approach.
92
00:11:43,452 --> 00:11:45,037
Over a short distance,
93
00:11:45,162 --> 00:11:48,999
she can strike five times
faster than a snake.
94
00:12:21,449 --> 00:12:22,867
Not today.
95
00:12:30,583 --> 00:12:35,379
But no worries. She's got
all the time in the world.
96
00:12:38,257 --> 00:12:42,261
It just takes one deer
to make one mistake,
97
00:12:43,053 --> 00:12:44,555
and she'll be waiting.
98
00:12:54,064 --> 00:12:57,359
Head north from the low-lying
swamps of the South...
99
00:13:02,114 --> 00:13:04,909
and you enter the vast
American heartland.
100
00:13:07,244 --> 00:13:09,622
All along the Mississippi River,
101
00:13:11,582 --> 00:13:14,627
over the spectacular
Badlands of South Dakota,
102
00:13:15,628 --> 00:13:19,173
open country of plains,
rivers, and forests
103
00:13:20,090 --> 00:13:22,760
stretch for 3,000 miles.
104
00:13:24,512 --> 00:13:27,807
All the way to the Arctic,
where North America
105
00:13:27,890 --> 00:13:31,519
reaches closer to the North
Pole than any other continent.
106
00:13:38,150 --> 00:13:39,318
In the middle,
107
00:13:39,610 --> 00:13:43,447
the prairies are the meeting place
for weather from north and south.
108
00:13:45,658 --> 00:13:50,496
Out here, you got to be ready
for all seasons in a day.
109
00:14:00,798 --> 00:14:02,675
One minute, it's
green all around.
110
00:14:04,969 --> 00:14:08,931
An hour later, snow everywhere.
111
00:14:14,270 --> 00:14:16,272
Be prepared for anything,
112
00:14:17,690 --> 00:14:20,067
whether you're big
like a bison...
113
00:14:22,444 --> 00:14:24,780
small like a prairie dog...
114
00:14:28,576 --> 00:14:30,995
or newly arrived for
the breeding season.
115
00:14:34,915 --> 00:14:36,458
Like this burrowing owl.
116
00:14:38,836 --> 00:14:43,132
The greatest temperature change
ever recorded on Earth in one day
117
00:14:43,257 --> 00:14:48,304
was on the U.S. prairie,
a 100-degree swing.
118
00:14:54,768 --> 00:14:56,186
Sunny and warm again.
119
00:15:00,190 --> 00:15:01,609
And now, it's raining.
120
00:15:07,740 --> 00:15:09,783
The heartland heroes
are used to it.
121
00:15:13,329 --> 00:15:14,413
Whatever!
122
00:15:17,207 --> 00:15:20,794
This hard-working prairie dog
mom takes it all in her stride.
123
00:15:22,630 --> 00:15:24,840
She's got demanding
kids to worry about.
124
00:15:26,967 --> 00:15:28,218
You know the feeling.
125
00:15:33,557 --> 00:15:37,645
Out here, though, it pays to
keep one eye on the weather.
126
00:15:43,692 --> 00:15:47,529
There's no mountains to block
winds blowing from north or south.
127
00:15:52,034 --> 00:15:53,661
So when the winds shift
128
00:15:54,703 --> 00:16:00,084
and freezing cold air from the Arctic
meets baking hot air from the tropics,
129
00:16:00,459 --> 00:16:02,461
things get nasty.
130
00:16:08,384 --> 00:16:10,427
Up above the prairie dog town,
131
00:16:11,387 --> 00:16:15,307
the most violent type of
thunderstorm on Earth is forming.
132
00:16:20,187 --> 00:16:21,480
A supercell.
133
00:16:23,857 --> 00:16:29,154
The warm air is pushing up through
the cold at 100 feet per second,
134
00:16:29,655 --> 00:16:31,365
sucking water vapor with it.
135
00:16:32,825 --> 00:16:36,745
The thundercloud can climb to
twice the height of Mount Everest.
136
00:16:39,623 --> 00:16:44,253
The low rumble of a storm
alerts animals for miles around.
137
00:16:46,463 --> 00:16:48,924
In the most extreme supercells,
138
00:16:49,008 --> 00:16:54,304
the movement of warm and cold
airstreams creates a spinning vortex.
139
00:16:56,724 --> 00:17:00,561
The birth of one of the planet's
most destructive forces.
140
00:17:05,190 --> 00:17:06,400
A tornado.
141
00:17:11,655 --> 00:17:14,825
Over 1,000 touch
down here every year.
142
00:17:22,583 --> 00:17:25,044
If you've got a
burrow, use it now.
143
00:17:33,635 --> 00:17:37,097
Wind speeds can hit
over 300 miles per hour,
144
00:17:37,723 --> 00:17:39,308
the strongest winds on Earth.
145
00:18:09,838 --> 00:18:13,133
Tornadoes are getting more
widespread as our climate warms.
146
00:18:14,093 --> 00:18:16,011
A big challenge for people,
147
00:18:16,220 --> 00:18:18,972
but for the burrow dwellers
of the Great Plains,
148
00:18:19,098 --> 00:18:22,226
a tornado is just a
minor inconvenience.
149
00:18:30,901 --> 00:18:33,195
Mama prairie dog gets
straight on with rebuilding
150
00:18:33,278 --> 00:18:34,321
the front porch.
151
00:18:37,366 --> 00:18:39,451
She even gets the
kids to help out.
152
00:18:51,088 --> 00:18:53,882
But wait, is that another
change in the wind?
153
00:19:02,516 --> 00:19:03,725
Oh, man!
154
00:19:10,399 --> 00:19:12,651
The heroes at the
heart of our continent
155
00:19:12,734 --> 00:19:14,695
endure the planet's
wildest weather.
156
00:19:19,491 --> 00:19:22,161
Travel out to the
sunny California coast,
157
00:19:23,120 --> 00:19:25,831
and the challenges for
life are way different.
158
00:19:27,624 --> 00:19:32,421
Just offshore from Los Angeles,
there's a special breed of hero.
159
00:19:39,011 --> 00:19:40,137
Dolphins.
160
00:19:44,600 --> 00:19:46,476
The secret to their success?
161
00:19:49,646 --> 00:19:50,647
Teamwork.
162
00:19:51,732 --> 00:19:54,276
There are more dolphins
per square mile here
163
00:19:54,359 --> 00:19:56,069
than anywhere else on Earth.
164
00:19:57,112 --> 00:19:59,740
A gang like this can
be 10,000 strong.
165
00:20:02,075 --> 00:20:06,246
Every one of them swimming as fast
as an Olympic sprinter can run.
166
00:20:15,923 --> 00:20:19,092
Today, they're hunting
within sight of Tinseltown.
167
00:20:25,724 --> 00:20:29,353
Working together, they
scour the ocean for prey.
168
00:20:36,610 --> 00:20:39,738
Soon, they round up a
giant school of anchovies.
169
00:20:50,040 --> 00:20:52,125
Other hunters spot
the opportunity.
170
00:20:56,838 --> 00:21:00,884
Californian sea lions
and diving seabirds.
171
00:21:09,434 --> 00:21:10,936
It looks like an easy meal.
172
00:21:13,230 --> 00:21:15,774
But the anchovies have
a dazzling defense.
173
00:21:18,151 --> 00:21:20,904
They stay close and
coordinate their movements.
174
00:21:24,032 --> 00:21:27,869
The blur of twisting and turning
fish confuses the hunters.
175
00:21:28,704 --> 00:21:30,664
They can't pick out
any single fish.
176
00:21:40,132 --> 00:21:42,342
This looks like a
job for team dolphin.
177
00:21:46,179 --> 00:21:48,140
They drive a wedge
into the shoal.
178
00:21:53,437 --> 00:21:57,816
Working together, they gradually break
the shoal up into smaller chunks.
179
00:22:17,753 --> 00:22:20,672
Now, it's easier to target
the individual fish.
180
00:22:26,303 --> 00:22:28,847
Every predator eats
as much as it can...
181
00:22:38,857 --> 00:22:41,151
before the gatecrashers arrive.
182
00:22:57,542 --> 00:23:02,464
A humpback whale can eat 80,000
anchovies in a single gulp.
183
00:23:08,970 --> 00:23:13,392
So, two whales together soon bring
an end to this Hollywood drama.
184
00:23:29,366 --> 00:23:31,868
Since humans were banned
from hunting whales,
185
00:23:32,536 --> 00:23:34,204
some have made a comeback here.
186
00:23:36,832 --> 00:23:38,667
Including the greatest of all.
187
00:23:44,172 --> 00:23:45,424
The blue whale.
188
00:23:51,555 --> 00:23:53,890
The biggest animal
that's ever lived.
189
00:23:55,100 --> 00:23:58,353
Up to 200 tons
and 100 feet long.
190
00:24:03,191 --> 00:24:07,404
North America is one of the best
places in the world to see blue whales.
191
00:24:12,033 --> 00:24:16,538
Almost as many live here now as
there were before hunting began.
192
00:24:25,213 --> 00:24:28,300
The rich Pacific sustains
these ocean giants,
193
00:24:29,759 --> 00:24:32,262
and also giants of the land.
194
00:24:37,559 --> 00:24:41,897
Off Northern California, fog
banks form over the cool ocean.
195
00:24:49,779 --> 00:24:52,032
Breezes blow the fog inland...
196
00:24:54,284 --> 00:24:57,746
where coastal redwoods,
the tallest trees on Earth,
197
00:24:58,288 --> 00:25:00,957
absorb the fog water
through their leaves.
198
00:25:07,297 --> 00:25:11,676
There are woodlands watered by the
ocean on our Atlantic Coast too.
199
00:25:14,304 --> 00:25:17,682
This is the only tropical
forest in the Lower 48.
200
00:25:19,184 --> 00:25:23,230
The South Florida home to
one of our smallest heroes.
201
00:25:25,815 --> 00:25:28,401
You're looking right at him.
202
00:25:36,243 --> 00:25:38,537
North America's tiniest toad.
203
00:25:41,748 --> 00:25:44,292
An oak toad, the
size of a nickel.
204
00:25:47,170 --> 00:25:48,755
He's got to head out to eat.
205
00:25:52,717 --> 00:25:55,554
The problem is, when
you're this small,
206
00:25:56,221 --> 00:25:59,474
pretty much everything
else wants to eat you.
207
00:26:01,643 --> 00:26:03,770
This little guy needs courage.
208
00:26:05,230 --> 00:26:10,360
For him, a 50-yard journey to
find food is a dangerous quest.
209
00:26:16,783 --> 00:26:19,160
With predators at every turn.
210
00:26:21,162 --> 00:26:25,083
In his path, the
biggest toad in America.
211
00:26:30,463 --> 00:26:32,549
At over ten times his size,
212
00:26:33,883 --> 00:26:36,636
this cane toad could
swallow him whole.
213
00:26:40,307 --> 00:26:42,517
Better hope the big
guy's not hungry.
214
00:26:54,988 --> 00:26:56,573
Oof. Lucky escape.
215
00:26:57,866 --> 00:26:59,659
It won't always be
so easy, though.
216
00:27:00,827 --> 00:27:03,496
Some hunters here are hungry.
217
00:27:09,502 --> 00:27:10,837
A garter snake.
218
00:27:20,805 --> 00:27:24,851
She smells the air with her
forked tongue to track her prey.
219
00:27:39,074 --> 00:27:40,825
She's nearly on him.
220
00:27:50,794 --> 00:27:52,545
But she loses the trail.
221
00:27:58,885 --> 00:28:04,182
Maybe the toad used the smell of
the snail to mask his own scent.
222
00:28:08,812 --> 00:28:11,064
It pays to be small sometimes.
223
00:28:17,237 --> 00:28:20,573
Now, there's just one last
predator in the toad's path.
224
00:28:23,034 --> 00:28:25,995
Perhaps the most
sinister of them all.
225
00:28:28,915 --> 00:28:31,751
A sundew, a carnivorous plant.
226
00:28:37,841 --> 00:28:42,303
It uses a sugary secretion
to lure in its prey.
227
00:28:49,602 --> 00:28:52,814
The ant is trapped by
the sticky droplets.
228
00:28:58,945 --> 00:29:02,532
Allowing the sundew
to slowly engulf it.
229
00:29:06,578 --> 00:29:08,037
A deadly predator...
230
00:29:09,664 --> 00:29:13,168
but just what the
toad's been looking for.
231
00:29:30,185 --> 00:29:34,397
He fires out his tongue faster
than the human eye can blink...
232
00:29:36,608 --> 00:29:39,652
stealing ants from the
sundew's sticky grip.
233
00:29:47,869 --> 00:29:50,455
Who doesn't love an
all-you-can-eat buffet?
234
00:30:07,889 --> 00:30:09,766
Brave and crafty,
235
00:30:10,225 --> 00:30:14,062
he's definitely a hero of
this lush coastal forest.
236
00:30:23,780 --> 00:30:26,741
Inland, America
is a drier world.
237
00:30:27,200 --> 00:30:31,996
In California, humid Pacific air
can't cross the High Sierras.
238
00:30:36,626 --> 00:30:40,088
Beyond is the driest
place in North America
239
00:30:41,005 --> 00:30:44,843
and the hottest place
on Earth, Death Valley.
240
00:30:46,344 --> 00:30:48,221
Named by European settlers
241
00:30:48,304 --> 00:30:51,099
who almost died crossing
this scorched plain.
242
00:30:59,148 --> 00:31:01,234
The western deserts
are the setting
243
00:31:01,317 --> 00:31:03,987
for some of the most
famous landscapes on Earth.
244
00:31:10,034 --> 00:31:12,203
Some are the stuff of legend.
245
00:31:15,665 --> 00:31:17,375
In the stories of the Navajo,
246
00:31:17,500 --> 00:31:20,503
the 1,000-foot-tall towers
of Monument Valley...
247
00:31:22,922 --> 00:31:25,341
are the bodies of
defeated monsters.
248
00:31:29,721 --> 00:31:33,099
The bare rock of these deserts
have been carved by the elements
249
00:31:33,182 --> 00:31:34,767
for thousands of years.
250
00:31:38,438 --> 00:31:40,189
With spectacular results.
251
00:31:44,319 --> 00:31:47,947
The Grand Canyon, the
largest canyon in America.
252
00:31:49,741 --> 00:31:52,535
Nearly 300 miles long...
253
00:31:54,829 --> 00:31:56,831
and over a mile deep.
254
00:31:59,709 --> 00:32:02,170
It's truly awe-inspiring.
255
00:32:07,091 --> 00:32:09,344
But how do you
make a living here?
256
00:32:12,680 --> 00:32:17,602
Rule one. You gotta be tough.
Able to endure months of drought.
257
00:32:19,771 --> 00:32:23,900
Rule two. Everyone,
from this mountain lion
258
00:32:24,025 --> 00:32:28,279
all the way down the food chain,
has to grasp the opportunity
259
00:32:28,404 --> 00:32:31,783
when rain does make it
beyond the mountains.
260
00:32:45,088 --> 00:32:46,589
When it rains here...
261
00:32:48,091 --> 00:32:52,011
it rains here, up to
two inches an hour.
262
00:33:05,692 --> 00:33:06,859
After the storm,
263
00:33:08,569 --> 00:33:10,905
all the locals
come out to drink.
264
00:33:19,706 --> 00:33:20,832
Even those,
265
00:33:21,541 --> 00:33:24,919
like this rattlesnake,
who usually stay hidden.
266
00:33:28,673 --> 00:33:29,924
For this roadrunner,
267
00:33:30,383 --> 00:33:34,095
the rain presents more than just
a chance to quench his thirst.
268
00:33:34,679 --> 00:33:36,681
He has his eye on a female.
269
00:33:42,812 --> 00:33:45,815
But despite his best efforts
at personal grooming,
270
00:33:47,400 --> 00:33:48,651
she's not interested.
271
00:33:55,408 --> 00:33:56,868
So, lucky for him,
272
00:33:57,201 --> 00:34:00,163
the rain has brought out what
he needs to impress his lady.
273
00:34:04,542 --> 00:34:05,626
Food.
274
00:34:12,175 --> 00:34:14,218
The perfect gift
for a first date...
275
00:34:16,554 --> 00:34:17,722
a scorpion.
276
00:34:34,113 --> 00:34:35,281
No luck there.
277
00:34:41,996 --> 00:34:43,623
How about a juicy lizard?
278
00:34:55,510 --> 00:34:57,178
Surely, this will win her heart.
279
00:34:57,595 --> 00:35:02,934
I mean, who couldn't resist fresh lizard
delivered with a shake of the tail?
280
00:35:29,127 --> 00:35:30,878
She's leading him on a dance.
281
00:35:33,047 --> 00:35:34,173
She's interested.
282
00:35:36,759 --> 00:35:39,428
But there's trouble ahead.
283
00:35:41,264 --> 00:35:42,890
The rattler is still out.
284
00:36:04,203 --> 00:36:06,497
The shock puts her off romance.
285
00:36:10,585 --> 00:36:11,794
It's too bad.
286
00:36:13,379 --> 00:36:16,132
But no unwanted gift
should go to waste.
287
00:36:22,471 --> 00:36:26,350
Especially in the desert,
where the good times
288
00:36:27,185 --> 00:36:28,644
usually don't last long.
289
00:36:32,690 --> 00:36:35,943
Out here, change can come fast.
290
00:36:42,491 --> 00:36:46,287
But for sheer scale of change,
head to the north of our continent.
291
00:36:56,297 --> 00:36:58,299
The White Mountains
of New Hampshire.
292
00:36:59,800 --> 00:37:03,638
Scene of one of the most famous
transformations on Earth.
293
00:37:10,603 --> 00:37:15,483
As winter approaches, the trees
lose pigments from their leaves.
294
00:37:19,570 --> 00:37:22,031
The cue for a magical display.
295
00:37:26,160 --> 00:37:28,663
The fall colors of New England.
296
00:37:47,139 --> 00:37:49,976
The color change sweeps
through the plants
297
00:37:50,434 --> 00:37:52,645
and the animals.
298
00:37:55,022 --> 00:37:59,026
Some caterpillars here
change color with the leaves.
299
00:38:10,871 --> 00:38:14,417
It's a neat trick, which means
they can stay camouflaged
300
00:38:14,500 --> 00:38:16,585
while their home
changes around them.
301
00:38:23,676 --> 00:38:28,139
The fall transformation is the
beginning of the great northern winter.
302
00:38:31,392 --> 00:38:33,936
Brutal... and beautiful.
303
00:38:41,986 --> 00:38:46,449
The northern lights dance over
the summit of Denali in Alaska,
304
00:38:48,075 --> 00:38:51,912
our highest mountain and
the coldest place on Earth
305
00:38:52,496 --> 00:38:53,914
outside of Antarctica.
306
00:39:01,547 --> 00:39:06,052
Through the long winter months,
the weak sun brings no warmth.
307
00:39:09,055 --> 00:39:12,266
So, you've got to be ready to
take advantage of the good times
308
00:39:12,892 --> 00:39:15,353
when spring finally comes.
309
00:39:26,280 --> 00:39:28,449
A caribou herd is on the move...
310
00:39:30,493 --> 00:39:33,120
seeking out the
newly exposed grass.
311
00:39:35,706 --> 00:39:38,626
But this female has
dropped behind the herd...
312
00:39:41,212 --> 00:39:42,713
to have her calf.
313
00:39:46,384 --> 00:39:49,470
He's the last-born youngster
of this calving season.
314
00:39:51,389 --> 00:39:55,726
It's going to take a heroic
effort from Mom to keep him safe.
315
00:40:00,398 --> 00:40:03,943
At just an hour old, she
pushes him to get moving.
316
00:40:05,820 --> 00:40:07,613
They're vulnerable alone.
317
00:40:10,241 --> 00:40:14,036
Way ahead, the herd
offers safety in numbers.
318
00:40:26,966 --> 00:40:29,635
She's nearly caught up
with another mom and calf
319
00:40:29,927 --> 00:40:32,096
who are also trailing
behind the herd.
320
00:40:35,558 --> 00:40:39,687
But her tiny, last-born calf
is struggling to keep pace.
321
00:40:45,526 --> 00:40:49,530
And the last place you want
to be is bringing up the rear.
322
00:40:52,741 --> 00:40:55,744
Grizzly bears are on
the caribous' tail,
323
00:40:56,078 --> 00:41:00,291
recently emerged from
hibernation and very hungry.
324
00:41:21,729 --> 00:41:24,523
This bear is more
desperate than most.
325
00:41:25,524 --> 00:41:29,153
She's a mother too, with
three young cubs in tow.
326
00:41:57,139 --> 00:42:01,435
The older calf tries to
keep safe by keeping still.
327
00:42:12,363 --> 00:42:13,656
But he panics.
328
00:42:21,830 --> 00:42:23,707
Mom calls to encourage him.
329
00:42:30,631 --> 00:42:32,633
But she's helpless
against the bear.
330
00:42:44,019 --> 00:42:45,729
Some battles can't be won.
331
00:42:51,443 --> 00:42:54,697
This small meal won't
sustain the bears for long.
332
00:43:00,244 --> 00:43:03,539
The mom of the youngest calf
needs to keep him on the move.
333
00:43:13,007 --> 00:43:15,426
Soon, they catch up with
the rest of the herd.
334
00:43:23,517 --> 00:43:26,979
The caribou choose a dangerous
route to shake off the bears.
335
00:43:30,357 --> 00:43:36,614
Ahead of the herd is a river, fast
flowing and swollen with melted snow.
336
00:43:43,162 --> 00:43:48,167
It's tough for the adults. For
the calves, it can be deadly.
337
00:43:52,129 --> 00:43:58,010
They've only just learned to
walk, and now, it's sink or swim.
338
00:44:03,182 --> 00:44:06,435
The mother of the youngest calf
has brought him safely this far,
339
00:44:07,895 --> 00:44:09,730
but she can't help
him with this.
340
00:44:16,028 --> 00:44:17,946
It's possible death in front...
341
00:44:19,823 --> 00:44:21,659
or certain death behind.
342
00:44:34,672 --> 00:44:39,176
Where she leads,
hopefully, he'll follow.
343
00:45:07,246 --> 00:45:08,706
He's struggling to swim.
344
00:45:46,285 --> 00:45:47,453
He's made it!
345
00:45:49,663 --> 00:45:52,332
The bear won't risk
crossing with her cubs.
