1
00:00:02,000 --> 00:00:03,950
A land of breathtaking beauty
2
00:00:04,000 --> 00:00:05,950
and cruel extremes ��
3
00:00:07,500 --> 00:00:10,450
Bitterly cold winters and treacherous terrain.
4
00:00:18,400 --> 00:00:21,150
For the animals it's a test of endurance,
5
00:00:21,200 --> 00:00:23,450
will and domination��
6
00:00:26,200 --> 00:00:28,150
This is Denali��
7
00:00:28,200 --> 00:00:32,650
wild, majestic and savage.
8
00:01:17,400 --> 00:01:21,750
At the center of this stunning landscape
in Alaska's Denali national park
9
00:01:21,800 --> 00:01:23,950
is North America's tallest peak,
10
00:01:24,000 --> 00:01:25,950
Mount McKinley.
11
00:01:27,800 --> 00:01:30,250
At over 6000 meters high,
12
00:01:30,300 --> 00:01:33,650
McKinley towers over a 650 km span
13
00:01:33,700 --> 00:01:36,550
of jagged mountains called the Alaska range
14
00:01:36,600 --> 00:01:39,450
it's the heart of central Alaska.
15
00:01:44,200 --> 00:01:45,750
Below the towering peaks
16
00:01:45,800 --> 00:01:49,250
lies a sub-arctic wilderness the size of Wales.
17
00:01:49,500 --> 00:01:52,550
With peaks and ridges rising over 3000m
18
00:01:52,600 --> 00:01:54,450
and its proximity to the Arctic,
19
00:01:54,700 --> 00:01:57,950
Mt. McKinley creates its own weather system,
20
00:01:58,000 --> 00:02:01,350
producing unimaginably cold winters.
21
00:02:04,300 --> 00:02:07,150
The landscape is as savage as the climate.
22
00:02:07,700 --> 00:02:11,650
Grinding rivers of glacial ice
carve out massive cliffs
23
00:02:11,700 --> 00:02:13,650
thousands of meters tall.
24
00:02:16,400 --> 00:02:18,350
Climbers may conquer the summit
25
00:02:18,400 --> 00:02:21,550
but none can tame this mountain
26
00:02:28,500 --> 00:02:31,950
An avalanche is one of nature's
most commanding displays,
27
00:02:36,400 --> 00:02:39,450
Giant slabs of ice weighing thousands of tons
28
00:02:39,500 --> 00:02:42,750
and moving at speeds of up to 400 km/h
29
00:02:42,800 --> 00:02:45,950
rumble and crash down the mountain sides.
30
00:02:54,900 --> 00:02:58,950
The night sky displays
an even more spectacular scene
31
00:03:01,400 --> 00:03:04,050
A stream of charged particles from the sun
32
00:03:04,100 --> 00:03:08,250
performs an illuminating dance
with the earth's magnetic field.
33
00:03:17,500 --> 00:03:20,150
It's Mother Nature's own fireworks display
34
00:03:20,200 --> 00:03:23,150
and it casts a spell over this frozen tundra.
35
00:03:24,500 --> 00:03:26,550
Where nature is not just raw -
36
00:03:26,600 --> 00:03:28,450
it's unrelenting.
37
00:03:36,300 --> 00:03:39,250
The sun travels to the other end of the world
38
00:03:39,300 --> 00:03:41,850
and daylight all but disappears.
39
00:03:49,100 --> 00:03:51,250
The haunting howl of an alpha male
40
00:03:51,300 --> 00:03:53,450
stabs at the Arctic night.
41
00:03:56,100 --> 00:03:57,250
For the wolves,
42
00:03:57,300 --> 00:04:00,450
survival is a constant battle with starvation.
43
00:04:05,600 --> 00:04:07,150
With the light of a full moon,
44
00:04:07,200 --> 00:04:09,450
North America's premier predator
45
00:04:09,500 --> 00:04:11,050
is on the hunt for a meal.
46
00:04:16,500 --> 00:04:18,550
Wolves are fiercely territorial.��
47
00:04:18,600 --> 00:04:20,550
But their best chance for finding food
48
00:04:20,600 --> 00:04:22,450
is by hunting in a pack.
49
00:04:26,700 --> 00:04:30,450
On this icy night the odds
are in their favor.
50
00:04:36,700 --> 00:04:40,650
This moose buffet means fine
dining for everyone.
51
00:04:47,400 --> 00:04:50,650
Searching for food in the treacherous
cold of the Denali winter
52
00:04:50,700 --> 00:04:53,750
tests the limits of even
the hardiest of carnivores.
53
00:04:58,300 --> 00:05:01,850
Winter in Denali is nature's killing season ��
54
00:05:02,500 --> 00:05:05,350
Temperatures drop to 10 degrees below zero.
55
00:05:09,700 --> 00:05:11,250
Many of the smaller creatures
56
00:05:11,300 --> 00:05:15,450
retreat to the depths to find what
shelter they can from the elements.
57
00:05:15,500 --> 00:05:18,950
This frozen tundra is just a temporary tomb.
58
00:05:23,100 --> 00:05:25,950
The wood frog-Denali's only amphibian
59
00:05:26,000 --> 00:05:29,450
survives the winter by freezing
itself into a block of ice.
60
00:05:30,300 --> 00:05:31,950
As the water temperature drops,
61
00:05:32,000 --> 00:05:34,150
the frog produces a sugary fluid,
62
00:05:34,200 --> 00:05:38,450
or antifreeze to protect all of
its vital systems from rupturing.
63
00:05:47,200 --> 00:05:50,250
Another park resident,
the Arctic ground squirrel,
64
00:05:50,300 --> 00:05:53,650
also has a unique way of
enduring the killer cold.
65
00:05:53,700 --> 00:05:56,150
He retreats underground to hibernate.
66
00:05:58,100 --> 00:05:59,250
During this sleep
67
00:05:59,300 --> 00:06:01,150
he adopts the lowest body temperature
68
00:06:01,200 --> 00:06:02,950
ever measured in a mammal.
69
00:06:03,500 --> 00:06:05,450
To create heat to warm his body,
70
00:06:05,500 --> 00:06:07,150
he convulses his muscles.
71
00:06:07,200 --> 00:06:11,450
He will shiver and shake
for 12 to 15 hours at a time.
72
00:06:23,200 --> 00:06:25,850
Every 2 to 3 weeks, For a few hours,
73
00:06:25,900 --> 00:06:27,950
the squirrel will become alert
74
00:06:28,000 --> 00:06:31,250
- walk around and then
settle back into a deep sleep
75
00:06:31,300 --> 00:06:33,750
and the cycle will begin again.
76
00:06:41,300 --> 00:06:46,750
Of the estimated 58,000 brown bears
in North America in 2001
77
00:06:46,800 --> 00:06:49,150
more than half live in Alaska.
78
00:06:50,100 --> 00:06:53,950
The female grizzly bear is nestled
in her den for the winter
79
00:06:54,000 --> 00:06:56,450
where she will enter a period of dormancy.
80
00:07:02,900 --> 00:07:05,350
Her sleep is a sort of hibernation
81
00:07:05,400 --> 00:07:07,250
but her body temperature doesn't drop.
82
00:07:07,600 --> 00:07:11,250
A thick fur coat and heavy layers
of fat keep her warm
83
00:07:11,300 --> 00:07:14,250
even when temperatures plunge below zero.
84
00:07:22,200 --> 00:07:26,050
The long, cold season is the
perfect time for her to lie around,
85
00:07:26,100 --> 00:07:29,750
conserve her fat stores and care
for her infant cubs,
86
00:07:29,800 --> 00:07:31,150
born mid-winter.
87
00:07:47,800 --> 00:07:49,850
At birth, the cubs are blind,
88
00:07:49,900 --> 00:07:52,350
and weigh less than half a kilogram.
89
00:07:52,400 --> 00:07:53,650
For the next few months,
90
00:07:53,700 --> 00:07:55,750
they are content to snuggle and nurse
91
00:07:55,800 --> 00:07:57,450
in the shelter of the den.
92
00:08:01,500 --> 00:08:03,050
At the end of the summer season,
93
00:08:03,100 --> 00:08:05,850
the mother bear weighs around 200kg.
94
00:08:06,400 --> 00:08:07,650
For the next few months,
95
00:08:07,700 --> 00:08:09,850
she will have to live off her summer fat,
96
00:08:09,900 --> 00:08:11,350
and by the end of winter,
97
00:08:11,400 --> 00:08:14,550
she'll have lost up to 70kg of body fat.
98
00:08:41,000 --> 00:08:43,850
This family will sleep away
the winter for months,
99
00:08:43,900 --> 00:08:46,050
inside their earthen shelter.
100
00:08:46,300 --> 00:08:49,250
Many others are not so lucky.
101
00:08:56,100 --> 00:08:58,950
For those creatures that cannot
retreat from the brutal winter
102
00:08:59,000 --> 00:09:01,150
beneath this frozen Mt. McKinley,
103
00:09:01,300 --> 00:09:04,950
it's hard to imagine a less
hospitable environment.
104
00:09:11,700 --> 00:09:14,550
Deep snow slows a moose and her calf,
105
00:09:14,600 --> 00:09:16,550
not yet a year old.
106
00:09:31,100 --> 00:09:34,350
While moose and caribou keep
vigil against hungry wolves,
107
00:09:34,700 --> 00:09:37,350
There's no evading Denali's
fiercest predator:
108
00:09:37,400 --> 00:09:41,750
In the Arctic, temperatures
can dip past 40 below
109
00:09:41,800 --> 00:09:45,750
and winds can reach speeds
of up to 160km/h,
110
00:09:45,800 --> 00:09:49,150
Winter is the supreme killer.
111
00:09:52,200 --> 00:09:53,550
Food is scarce.
112
00:09:53,600 --> 00:09:55,150
The elements - harsh.
113
00:09:55,200 --> 00:09:58,250
And the combination - fatal.
114
00:09:59,600 --> 00:10:02,250
Here nothing goes to waste.
115
00:10:04,100 --> 00:10:07,150
A dead caribou attracts a long tailed weasel.
116
00:10:07,200 --> 00:10:10,450
It offers both room - and board.
117
00:10:12,200 --> 00:10:14,150
In this natural freezer,
118
00:10:14,200 --> 00:10:16,450
the meat will last for weeks.
119
00:10:35,300 --> 00:10:39,150
Here the weasel will dine and live
in comfort in his "trophy home"
120
00:10:39,200 --> 00:10:41,450
through the final days of winter.
121
00:10:56,500 --> 00:10:57,750
By late April
122
00:10:57,800 --> 00:11:00,850
for those who have survived
Denali's deep freeze
123
00:11:00,900 --> 00:11:03,850
a bracing spring is their only reward.
124
00:11:05,500 --> 00:11:07,850
The air may still be freezing cold,
125
00:11:08,400 --> 00:11:09,950
but for now at least,
126
00:11:10,000 --> 00:11:12,550
the days stretch as long as the nights.
127
00:11:19,100 --> 00:11:21,450
Mount McKinley's frozen tundra
128
00:11:21,500 --> 00:11:24,650
is melting into spring
and beginning to thaw.
129
00:11:26,700 --> 00:11:31,050
Over 600 varieties of flowering
plants burst from the ground
130
00:11:31,100 --> 00:11:35,950
as the sub Arctic begins to transform
itself into a land of plenty.
131
00:11:45,200 --> 00:11:47,150
From thousands of kilometers away,
132
00:11:47,200 --> 00:11:51,350
a wide variety of birds arrive
to enjoy the balmy weather.
133
00:12:01,400 --> 00:12:04,950
The golden eagles are returning
from their long migration.
134
00:12:05,200 --> 00:12:07,850
Soaring in with a 2m wingspan
135
00:12:07,900 --> 00:12:11,850
these birds come from places as
far away as Montana and Colorado
136
00:12:11,900 --> 00:12:14,550
to summer on Alaska's north slope.
137
00:12:14,800 --> 00:12:19,250
For many the roundtrip more than 7,000km
138
00:12:33,400 --> 00:12:37,450
Several hundred golden eagles
make Denali their summer home
139
00:12:37,500 --> 00:12:41,750
Some returning each year
to reunite with a life long mate.
140
00:12:48,700 --> 00:12:50,750
Below the ice-capped peaks,
141
00:12:50,800 --> 00:12:52,250
winter retreats
142
00:12:52,500 --> 00:12:55,550
as spring steals over the rest of the park.
143
00:13:04,500 --> 00:13:06,650
After a 7-month gestation,
144
00:13:06,700 --> 00:13:11,150
the caribou will celebrate this
change of season by giving birth.
145
00:13:22,300 --> 00:13:24,950
Some are just days from delivery.
146
00:13:25,000 --> 00:13:28,150
Others already shepherd newborn calves.
147
00:13:30,100 --> 00:13:31,650
The newest members of the park
148
00:13:31,700 --> 00:13:34,050
see Denali at its most forgiving.
149
00:13:34,400 --> 00:13:37,250
The sun now shines 16 hours a day,
150
00:13:37,300 --> 00:13:40,750
penetrating the beds of
even the deepest sleepers.
151
00:14:15,200 --> 00:14:19,350
The sun's powerful rays saturate
the frozen wood frog,
152
00:14:19,400 --> 00:14:21,350
melting his winter tomb.
153
00:15:00,500 --> 00:15:05,650
Miraculously, an icy death grip
yields to life resurrected.
154
00:15:18,200 --> 00:15:21,250
Just as the frog's winter
crust of ice melts away,
155
00:15:21,500 --> 00:15:26,150
the thousands of ponds and lakes in the
Denali wilderness begin to melt, too.
156
00:15:36,300 --> 00:15:40,250
The forbidding icescape becomes
a glittering water park.
157
00:15:45,700 --> 00:15:48,750
A band of beavers celebrates the final thaw.
158
00:15:48,800 --> 00:15:52,950
Their carefully constructed sanctuary
is finally free of ice.
159
00:16:00,500 --> 00:16:03,450
Now their winter watering
hole is a lush pond,
160
00:16:03,500 --> 00:16:06,050
drawing animals from all over the park
161
00:16:08,700 --> 00:16:12,150
This young moose enjoys
the pond's shallow banks,
162
00:16:12,200 --> 00:16:16,350
not realizing that he is about
to pay a price for his new pool.
163
00:16:19,500 --> 00:16:22,950
For a year, he has clung to
his mother's side for protection.
164
00:16:23,400 --> 00:16:27,450
That sheltered existence
is about to end - abruptly.
165
00:16:27,500 --> 00:16:29,050
With another calf on the way,
166
00:16:29,100 --> 00:16:31,550
she can no longer afford to care for him.
167
00:17:29,100 --> 00:17:31,650
In just a few minutes, her calf is born.
168
00:17:32,700 --> 00:17:35,750
And the new born will
need all her attention.
169
00:17:41,900 --> 00:17:44,350
Wolves, bears and even other moose
170
00:17:44,400 --> 00:17:46,650
pose a threat to the fragile calf.
171
00:17:46,700 --> 00:17:49,750
To stay alive, it must grow up quickly.
172
00:17:51,900 --> 00:17:53,150
Only a few minutes old,
173
00:17:53,200 --> 00:17:55,350
the calf struggles to stand.
174
00:17:55,400 --> 00:17:58,950
His first wobbly steps do not come easily.
175
00:18:21,500 --> 00:18:23,250
Surrounded by splendor,
176
00:18:23,300 --> 00:18:25,150
the mother sees only danger -
177
00:18:25,400 --> 00:18:28,350
And now must replace her fight
against the elements of nature
178
00:18:28,400 --> 00:18:30,950
with a constant vigil to protect her young.
179
00:18:31,400 --> 00:18:34,150
Survival is never assured.
180
00:18:39,400 --> 00:18:42,850
The dazzling if brief weeks
of high summer are here,
181
00:18:42,900 --> 00:18:44,650
but even in these days of plenty
182
00:18:44,700 --> 00:18:46,750
this world can be unforgiving.
183
00:19:01,900 --> 00:19:03,550
The mother moose and her new calf
184
00:19:03,600 --> 00:19:05,450
make their way down the river
185
00:19:05,500 --> 00:19:08,550
but a growing problem tags close behind.
186
00:19:10,800 --> 00:19:13,850
Last year's calf refuses
to make way for baby,
187
00:19:14,600 --> 00:19:17,050
and the mother can't look after both.
188
00:19:26,500 --> 00:19:29,550
Once a calf reaches maturity,
like this yearling,
189
00:19:29,600 --> 00:19:31,550
she must push him out on his own.
190
00:19:31,600 --> 00:19:34,350
If necessary, by force.
191
00:20:03,100 --> 00:20:06,250
Finally, like a defiant teenager leaving home,
192
00:20:06,300 --> 00:20:08,250
the young moose wanders off in a huff
193
00:20:08,300 --> 00:20:10,350
to find his own way in the world.
194
00:20:11,600 --> 00:20:14,150
It's a rough start to independence.
195
00:20:20,300 --> 00:20:23,150
On higher terrain, after his winter sleep,
196
00:20:23,200 --> 00:20:26,550
The Arctic ground squirrel,
is ready to eat and play,
197
00:20:28,600 --> 00:20:30,850
But he keeps a careful look out
198
00:20:30,900 --> 00:20:32,250
He has so many predators
199
00:20:32,300 --> 00:20:35,250
he is sometimes referred
to as "the staff of life" ��
200
00:20:35,300 --> 00:20:37,950
A meal for everyone in Denali.
201
00:20:43,200 --> 00:20:46,450
And one of his greatest enemies
- the grizzly bear
202
00:20:46,500 --> 00:20:48,450
- is on the prowl.
203
00:20:53,700 --> 00:20:56,550
After months underground,
groggy and famished
204
00:20:56,600 --> 00:20:59,350
she is on the hunt not only for herself,
205
00:20:59,400 --> 00:21:01,850
but for her five-month-old cubs.
206
00:21:22,400 --> 00:21:25,150
There is a new world to explore outside,
207
00:21:25,200 --> 00:21:27,650
and it's a lot more entertaining
than the winter den.
208
00:21:29,500 --> 00:21:32,250
Sledding is an unexpected surprise.
209
00:21:37,600 --> 00:21:40,450
However, this field trip's not just for fun.
210
00:21:40,800 --> 00:21:43,550
For her cubs, 2 females and one male
211
00:21:43,600 --> 00:21:46,050
it's a lesson in survival ��
212
00:21:46,500 --> 00:21:47,650
Lesson one -
213
00:21:47,700 --> 00:21:50,150
Never abandon the quest for food.
214
00:21:50,900 --> 00:21:54,350
Grizzlies can consume up
to 40kg of food a day
215
00:21:54,400 --> 00:21:56,350
to build up to their winter weight.
216
00:21:57,000 --> 00:21:58,250
Lesson two -
217
00:21:58,300 --> 00:22:01,150
Arctic squirrels make for a tasty treat.
218
00:22:01,500 --> 00:22:04,550
Their mother shows them how
to sniff out a snack.
219
00:22:05,200 --> 00:22:07,650
The 2 females make good students,
220
00:22:07,900 --> 00:22:11,250
but the world around the
young male distracts him.
221
00:22:11,900 --> 00:22:16,150
and his youthful energy will
soon turn this playful outing
222
00:22:16,200 --> 00:22:18,650
into a perilous event.
223
00:22:38,500 --> 00:22:41,150
As the mother bear continues to forage,
224
00:22:41,200 --> 00:22:45,950
no one notices that the family
has left a defenseless cub behind.
225
00:23:00,900 --> 00:23:04,950
Overhead, a golden eagle heads
home to her own young.
226
00:23:23,200 --> 00:23:26,350
Their mainstay is also the ground squirrel.
227
00:23:26,800 --> 00:23:29,050
Smaller mouths require little bites
228
00:23:29,100 --> 00:23:32,950
so she rips the meat into tiny
chunks for her hungry chick.
229
00:23:41,200 --> 00:23:43,850
As the baby bird feasts in safety,
230
00:23:43,900 --> 00:23:47,650
the cub below realizes his careless mistake.
231
00:23:49,600 --> 00:23:51,350
Alone and abandoned,
232
00:23:51,400 --> 00:23:53,450
the little bear is hopelessly lost.
233
00:23:54,600 --> 00:23:57,850
This is a risky place
for cubs to wander alone.
234
00:23:59,400 --> 00:24:02,450
His greatest danger is another male bear.
235
00:24:02,800 --> 00:24:06,550
Adult grizzlies will kill
a rival's cubs not for food,
236
00:24:06,600 --> 00:24:08,450
but to mate with the mother.
237
00:24:14,200 --> 00:24:15,550
In a desperate panic,
238
00:24:15,600 --> 00:24:18,650
the young bear realizes
he is in serious trouble.
239
00:24:18,700 --> 00:24:21,550
He bleats a terrified call for help.
240
00:24:23,700 --> 00:24:24,850
But his mayday
241
00:24:24,900 --> 00:24:27,450
may bring the wrong kind of attention.
242
00:24:32,300 --> 00:24:34,550
It feels like an eternity,
243
00:24:34,600 --> 00:24:37,950
but finally, the mother bear spots her son.
244
00:24:57,500 --> 00:24:59,250
Despite a serious scare,
245
00:24:59,300 --> 00:25:03,050
this cub will live to enjoy
all of Denali's spring.
246
00:25:34,500 --> 00:25:38,250
Throughout the park, love is in the air
247
00:25:40,600 --> 00:25:44,150
And all of the inhabitants seem
to feel the thrill of the season.
248
00:26:03,600 --> 00:26:06,350
Even as they enjoy their newest families,
249
00:26:06,400 --> 00:26:09,450
creatures small and large plan for the future.
250
00:26:09,600 --> 00:26:11,250
It's time to mate.
251
00:26:32,900 --> 00:26:37,250
Only another grizzly could find
affection in this rugged embrace.
252
00:26:47,500 --> 00:26:48,950
As with many species,
253
00:26:49,000 --> 00:26:50,950
the male must prove his worthiness
254
00:26:51,000 --> 00:26:53,950
before this reluctant female is convinced.
255
00:27:04,500 --> 00:27:06,250
In this savage land,
256
00:27:06,300 --> 00:27:09,850
even courtship requires
a survivor's instincts.
257
00:27:24,900 --> 00:27:27,950
Summer in Denali is a time
of great abundance��
258
00:27:28,200 --> 00:27:30,550
But not a time to lower your defenses.
259
00:27:31,100 --> 00:27:33,250
For the mother moose
and her week-old calf,
260
00:27:33,300 --> 00:27:37,650
even a brief stop at the watering
hole is tense and guarded.
261
00:27:45,500 --> 00:27:47,450
The mother sniffs the air.
262
00:27:47,700 --> 00:27:50,050
She is constantly alert to predators
263
00:27:50,400 --> 00:27:51,550
without protection;
264
00:27:51,600 --> 00:27:54,050
her calf would be an easy meal.
265
00:28:08,700 --> 00:28:11,150
She smells something on the wind
266
00:28:11,200 --> 00:28:13,550
the scent of a wolf.
267
00:28:19,900 --> 00:28:22,250
Quickly, the mother circles around her calf
268
00:28:22,300 --> 00:28:23,750
before he can attack.
269
00:29:27,200 --> 00:29:28,750
Without the element of surprise,
270
00:29:28,800 --> 00:29:32,650
the wolf is no match for
the mother's size and fury.
271
00:29:33,200 --> 00:29:36,750
A well-placed kick could crack
the wolf's cunning head.
272
00:29:49,700 --> 00:29:51,750
The wolves finally retreat,
273
00:29:51,800 --> 00:29:55,450
but the mother knows it might
only be a temporary respite.
274
00:30:16,500 --> 00:30:20,850
Down stream, the waters braid
through flood plains of gravel.
275
00:30:21,200 --> 00:30:23,350
The warm, sun filled tributaries
276
00:30:23,400 --> 00:30:25,250
become a wildlife retreat.
277
00:30:29,900 --> 00:30:33,250
Wolves are not the only animals
who frequent these streams.
278
00:30:33,600 --> 00:30:36,050
As the summer sun melts the mountain's ice,
279
00:30:36,100 --> 00:30:38,950
the growing river swells with Arctic water,
280
00:30:39,100 --> 00:30:41,950
and Animals of all sizes come to drink.
281
00:30:51,700 --> 00:30:54,650
Water carries sediment down
from melting glaciers,
282
00:30:54,700 --> 00:30:56,850
creating a grand calligraphy
283
00:31:05,900 --> 00:31:07,550
Natures brush strokes,
284
00:31:07,600 --> 00:31:10,650
ever changing on the canvas of Denali.
285
00:31:38,200 --> 00:31:42,250
A few days older, the moose calf
has grown more confident.
286
00:31:42,400 --> 00:31:43,750
But at this time of year,
287
00:31:43,800 --> 00:31:46,150
danger can come from any where.
288
00:31:47,900 --> 00:31:51,950
Unlike before, this hunter
is bigger and badder.
289
00:31:53,500 --> 00:31:56,450
And the moose does not see him coming.
290
00:32:00,700 --> 00:32:03,550
A full grown grizzly stands 2m tall
291
00:32:03,700 --> 00:32:06,250
and averages almost 400kg.
292
00:32:06,900 --> 00:32:08,550
Despite his enormous bulk,
293
00:32:08,600 --> 00:32:09,950
when chasing prey,
294
00:32:10,000 --> 00:32:13,350
he can reach speeds of 56km/h.
295
00:32:15,200 --> 00:32:18,150
For the moose, running is not an option
296
00:32:18,200 --> 00:32:20,250
but hiding is.
297
00:32:20,300 --> 00:32:23,350
The mother camouflages her calf
in a group of trees.
298
00:32:23,600 --> 00:32:26,150
But bears have a keen sense of smell.
299
00:32:26,200 --> 00:32:29,950
The mother knows, it's only a matter
of time until he finds them.
300
00:32:32,400 --> 00:32:34,150
Desperate to save her calf,
301
00:32:34,200 --> 00:32:36,150
she shows herself to the bear,
302
00:32:36,200 --> 00:32:37,750
hoping to lure him away.
303
00:32:46,600 --> 00:32:48,450
The ploy begins to work.
304
00:32:48,500 --> 00:32:50,150
The bear follows her lead-
305
00:32:50,500 --> 00:32:53,250
Then something goes terribly wrong.
306
00:32:55,000 --> 00:32:57,350
The young calf can't control his fear
307
00:32:57,400 --> 00:32:58,450
he runs.
308
00:33:05,200 --> 00:33:06,650
And with a clumsy step,
309
00:33:06,700 --> 00:33:09,750
his inexperience gives him away.
310
00:33:13,000 --> 00:33:15,650
The grizzly is on him in seconds.
311
00:33:44,800 --> 00:33:47,950
The distraught mother remains
close by for a time
312
00:33:48,000 --> 00:33:49,950
but there is nothing she can do.
313
00:34:00,900 --> 00:34:04,450
Survival in this wilderness
is far from guaranteed.
314
00:34:04,700 --> 00:34:07,250
And mother nature doesn't play favorites
315
00:34:07,700 --> 00:34:11,150
predation is a natural part of this landscape.
316
00:34:25,200 --> 00:34:26,950
The wilderness of Denali park
317
00:34:27,000 --> 00:34:28,950
is in transformation again.
318
00:34:29,700 --> 00:34:31,550
During mid-summer in the lowlands
319
00:34:31,600 --> 00:34:34,450
the days are filled with 20 hours of sunshine,
320
00:34:34,700 --> 00:34:37,550
plenty of time to rest and play.
321
00:35:05,400 --> 00:35:07,450
For these young ground squirrels,
322
00:35:07,500 --> 00:35:11,050
born weeks ago, spring is prime time.
323
00:35:11,100 --> 00:35:15,950
These energetic sprites scamper around
making the most of the warm weather.
324
00:35:18,600 --> 00:35:20,250
But while the young ones play,
325
00:35:20,300 --> 00:35:21,950
their parents are on the alert,
326
00:35:22,000 --> 00:35:24,250
keeping a close watch over the favored meal
327
00:35:24,300 --> 00:35:26,550
for many of the park's carnivores.
328
00:35:35,700 --> 00:35:38,850
Between the eagle, fox and bear populations
329
00:35:38,900 --> 00:35:43,450
just one in five of these Arctic ground
squirrels will survive to winter.
330
00:36:09,200 --> 00:36:12,650
It seems this grizzly just
loves a snack of squirrel
331
00:36:13,000 --> 00:36:17,950
They've been known to eat as many as 200
of the furry creatures in a single summer.
332
00:36:34,200 --> 00:36:37,650
For the bear, the hunt is just part of the fun.
333
00:36:37,900 --> 00:36:40,950
For the squirrel, it's pure terror.
334
00:36:45,800 --> 00:36:47,150
It's a shallow burrow
335
00:36:47,200 --> 00:36:50,450
offering little defense
against a determined grizzly.
336
00:37:01,300 --> 00:37:05,050
The bear's large razor sharp nails dig closer
337
00:37:05,100 --> 00:37:08,550
her snout locking in on the squirrel's scent.
338
00:37:13,400 --> 00:37:17,750
The giant hunter is within
centimeters of her tiny prize.
339
00:37:19,700 --> 00:37:23,450
Just then, a cub's call
distracts her from her snack
340
00:37:23,500 --> 00:37:25,750
and the bear turns away.
341
00:37:48,900 --> 00:37:51,750
This squirrel has been spared for today
342
00:37:52,100 --> 00:37:54,350
The mother bear settles down nearby,
343
00:37:54,500 --> 00:37:57,050
but keeps an eye on the meal that got away.
344
00:38:33,800 --> 00:38:36,250
During the height of Denali's brief summer
345
00:38:36,300 --> 00:38:39,150
there is plenty to eat for everyone.
346
00:38:40,300 --> 00:38:44,150
The lake-bottom plants are
a succulent meal for a bull moose��
347
00:38:45,700 --> 00:38:49,450
But vegetation is not the only
thing to thrive in these waters.
348
00:39:00,600 --> 00:39:03,550
Lurking just under the surface
of these Arctic streams,
349
00:39:03,600 --> 00:39:07,050
are mosquito larvae by the billions.
350
00:39:10,700 --> 00:39:13,750
These protrusions on their
heads are breathing tubes
351
00:39:13,800 --> 00:39:15,850
although they resemble devil horns
352
00:39:15,900 --> 00:39:19,350
- and look they defiantly deserve.
353
00:39:25,500 --> 00:39:28,350
One by one, they shed their larval skin
354
00:39:28,400 --> 00:39:30,450
and emerge as winged adults.
355
00:39:30,500 --> 00:39:32,750
tiny but fierce.
356
00:39:41,200 --> 00:39:43,150
This swarm makes life miserable
357
00:39:43,200 --> 00:39:45,550
for some of Denali's larger creatures.
358
00:40:05,900 --> 00:40:10,350
The miniature vampires find a meal
of molting caribou irresistible.
359
00:40:10,800 --> 00:40:12,750
The poor animals' patchy hides
360
00:40:12,800 --> 00:40:16,050
offer little defense against the insects' assault.
361
00:40:17,200 --> 00:40:18,950
As they feast on the caribou,
362
00:40:19,000 --> 00:40:20,950
they swell with blood.
363
00:40:27,100 --> 00:40:30,450
The incessant stinging
of bloodsucking mosquitoes
364
00:40:30,500 --> 00:40:33,750
will end only when summer wanes.
365
00:41:36,200 --> 00:41:39,750
The brief Denali summer is in transition.
366
00:41:45,700 --> 00:41:47,350
The days are getting shorter
367
00:41:47,400 --> 00:41:49,650
and showers wash the land.
368
00:42:02,900 --> 00:42:06,150
An enormous rainbow draws
an arc across the park,
369
00:42:06,200 --> 00:42:09,350
signaling an end to summer's bounty.
370
00:42:12,800 --> 00:42:14,750
Sensing the change in season,
371
00:42:14,800 --> 00:42:17,050
birds begin to migrate.
372
00:42:22,200 --> 00:42:24,050
After a summer of feasting,
373
00:42:24,100 --> 00:42:26,950
Denali's wildlife are in prime condition
374
00:42:27,200 --> 00:42:28,550
they now roam a wilderness
375
00:42:28,600 --> 00:42:31,450
growing colder and more still.
376
00:42:45,700 --> 00:42:48,550
Throughout the 24,000 sq km
377
00:42:48,600 --> 00:42:50,550
that make up the park and preserve,
378
00:42:50,600 --> 00:42:53,350
another transformation is taking place.
379
00:42:58,200 --> 00:43:03,350
An explosion of color shows itself
for a brief two weeks of autumn
380
00:43:03,400 --> 00:43:06,550
as the balance of power tips towards winter.
381
00:43:08,800 --> 00:43:10,150
For many creatures,
382
00:43:10,200 --> 00:43:12,050
there's time for one more feast
383
00:43:12,100 --> 00:43:13,950
before the winter sets in.
384
00:43:24,100 --> 00:43:26,650
These ptarmigan clean a tree branch of leaves
385
00:43:27,300 --> 00:43:30,850
as the young bear cubs scrounge
around for a final meal.
386
00:43:34,900 --> 00:43:36,650
Even the winter-ready beaver
387
00:43:36,700 --> 00:43:39,150
gathers a few more twigs for the dam.
388
00:43:43,200 --> 00:43:45,350
For one animal, the bull moose,
389
00:43:45,400 --> 00:43:47,750
autumn brings a final test.
390
00:43:48,200 --> 00:43:51,150
Males must fight for territory
and the right to mate
391
00:43:51,200 --> 00:43:53,250
before winter
392
00:43:55,200 --> 00:43:59,450
The velvety layer of skin that protected
the bull's antlers through spring and summer
393
00:43:59,500 --> 00:44:02,450
now hangs in bloody tatters.
394
00:44:02,500 --> 00:44:05,850
Bone bare, he is ready to fight.
395
00:44:12,900 --> 00:44:14,750
As the moose square off,
396
00:44:14,800 --> 00:44:17,250
other animals prepare for the coming winter
397
00:44:17,300 --> 00:44:18,750
in their own ways.
398
00:44:22,900 --> 00:44:25,150
Temperatures are dropping quickly now
399
00:44:25,200 --> 00:44:29,050
and Denali's creatures work
feverishly to gather food.
400
00:44:41,800 --> 00:44:44,150
The landscape darkens.
401
00:44:49,800 --> 00:44:52,650
The frog prepares for the deep freeze.
402
00:44:58,900 --> 00:45:01,950
Before the world succumbs to winter's slumber,
403
00:45:02,000 --> 00:45:04,950
this bull has won the right to breed.
404
00:45:05,500 --> 00:45:09,350
It is his way to ensure that
a new life in the coming spring
405
00:45:09,400 --> 00:45:11,950
will follow this dark season.
406
00:45:48,200 --> 00:45:50,750
The giant bull has found a willing cow,
407
00:45:50,800 --> 00:45:53,150
but a rival tries to move in...
408
00:46:17,200 --> 00:46:18,450
In this competition,
409
00:46:18,500 --> 00:46:20,650
size is everything
410
00:46:20,700 --> 00:46:22,350
and the bigger bull's antlers
411
00:46:22,400 --> 00:46:25,750
quickly convince the newcomer
to look elsewhere.
412
00:46:26,600 --> 00:46:29,850
The moose has little time
to consummate the union.
413
00:46:30,800 --> 00:46:32,750
Day by shortening day,
414
00:46:32,800 --> 00:46:35,450
the sun abandons this world.
415
00:46:37,500 --> 00:46:41,650
The darkness and cold of winter
regain their grip.
416
00:46:53,300 --> 00:46:56,550
As ice and snow cover this savage land,
417
00:46:56,600 --> 00:46:58,950
Denali's wildlife prepare for survival
418
00:46:59,000 --> 00:47:02,550
through another harsh, sub-arctic winter.
419
00:47:06,200 --> 00:47:09,350
In the majestic shadow
of Alaska's Mt. McKinley,
420
00:47:09,400 --> 00:47:12,950
a rich diversity of plant
and wildlife thrives��
421
00:47:13,400 --> 00:47:14,850
That, in itself,
422
00:47:14,900 --> 00:47:19,250
is a direct consequence of the amazingly
varied landscapes of our planet,
423
00:47:19,600 --> 00:47:22,850
Landscapes that remain untarnished ��
424
00:47:22,900 --> 00:47:24,950
At least for now.
425
00:47:25,800 --> 00:47:45,750
