Alaska: Spirit of the Wild

:00:13

Earth, 18,000 years
before the present

:00:25

it's a world locked in cold

:00:27

at the height
of the last great lce Age.

:00:36

Across tens
of thousands of years

:00:39

unmelting snows have compacted
into massive glaciers.

:00:44

Buried under ice sheets
averaging a mile thick

:00:48

are lands where
hundreds of millions live today.

:00:56

As Earth's water
is increasing locked up in ice

:01:00

sea levels plummet
more than a hundred meters.

:01:04

Exposed sea floor nearly joins
Australia to Southeast Asia

:01:16

Japan becomes part
of mainland Asia.

:01:37

Across North America,
ice fields and glaciers

:01:40

envelop all of Canada
and northernmost United States.

:01:50

As the lce Age spreads,
Alaska emerges as a crossroads.
