00:00:00,000 --> 00:00:05,000
The breaking of a 20,000-year silence, Los Glaciares.

2
00:00:08,000 --> 00:00:12,000
Patagonia lies on the southern tip of the South American continent.

3
00:00:12,000 --> 00:00:18,000
Humid air from the Pacific Ocean meets the Andes Mountains, creating dense clouds.

4
00:00:21,000 --> 00:00:24,000
The clouds' moisture falls as heavy snow.

5
00:00:25,000 --> 00:00:31,000
Los Glaciares is the third largest ice field in the world, after Antarctica and Greenland.

6
00:00:33,000 --> 00:00:37,000
Snowfall turns to ice and becomes part of the ice field.

7
00:00:42,000 --> 00:00:47,000
The ice is highly transparent and reflects blue light while absorbing all other colours.

8
00:00:47,000 --> 00:00:54,000
The blue ice is unique to Los Glaciares.

9
00:00:58,000 --> 00:01:02,000
The ice field has gradually increased in size over the past 20,000 years

10
00:01:02,000 --> 00:01:08,000
and now stretches from the mountains to the shore, forming a wall of ice over 10 metres high.

11
00:01:09,000 --> 00:01:14,000
The ice field provides Patagonia with abundant water and nature unique to the area.

12
00:01:17,000 --> 00:01:21,000
There are plants resistant to the strong westerly winds.

13
00:01:24,000 --> 00:01:27,000
Guanaco is a typical Patagonian animal.

14
00:01:27,000 --> 00:01:31,000
Although belonging to the camel family, it does not have humps.

15
00:01:32,000 --> 00:01:36,000
A one-kilometre chunk of ice broke off in 1994.

16
00:01:38,000 --> 00:01:42,000
The giant icebergs floating in the lake are covered in ice.

17
00:01:43,000 --> 00:01:46,000
The ice has been frozen for years.

18
00:01:47,000 --> 00:01:50,000
The ice has been frozen for years.

19
00:01:51,000 --> 00:01:54,000
The ice has been frozen for years.

20
00:01:55,000 --> 00:01:58,000
The ice has been frozen for years.

21
00:01:58,000 --> 00:02:02,000
The giant icebergs floating in the lake are chunks of glacier.

22
00:02:07,000 --> 00:02:14,000
Los Glaciares, here at the tip of the South American continent, are breaking their 20,000 years of silence.
