Both poles of our planet are covered with ice
They're the largest and most demanding wildernesses of all
Nowhere else on earth is seasonal change so extreme
It causes the ice to advance and retreat every year
and all life here is governed by that
When the first polar explorers headed south
giant cathedrals of ice marked their entry into uncharted territory
Passing the towering spires
they must have wondered what unearthly sights lay in store
As they battled on the ice became increasingly dominant
but nothing could have prepared them for the ice world
that finally loomed into view
Terra incognita - the unknown land
At the southernmost extreme of our planet
the continent of Antarctica
is as large as the United States of America
