Frozen Planet - E1 to the end of the earth S6

1. Frozen Planet - S01 - E01 - To The Ends Of The Earth - Part 06.mp3

Journeying south across the Arctic Ocean, the first land you reach in Greenland, the largest island in the world.

Despite its name, Greenland is mostly white, covered by a giant ice sheet six times the size of the United Kingdom.

In the middle of the island, the ice is nearly two miles thick. It's a bleak, quiet world.

Sapphire-blue melt lakes are the first sign that a dynamic process is underway.

Each lake forms in a matter of days, expanding until it's miles across and starts to overflow.

The spill water then carves its way through the ice.

The water courses through an icy delta like blood along the arteries of a cold-blooded monster,

a monster that is stirring.

And without warning, the water suddenly plunges down an open shaft, 

falling a vertical mile into the heart of the ice sheet.
