As the warm humid air from the south meet the cold Arctic, the moisture is crystalized and snowflakes form from the sky. Each crystal froms around a particle of dust. All have a six-fold symmetry, but no two have ever been found with exactly the same shape. Their variety and complexity is breathtaking.Each snowflake is water waiting to be released in spring. For this reason, snow is the lifeblood of these silent forests and all that live here depend on it in one way or another. Some, like the great grey owl, appear in spring for the booming times then vanish like phantoms. Others, like their lemming prey, are here year around beneath the snow, insulated from the cold air above.The northern forests are across road for seasonal visitors and Arctic specialists. But they are so much more than this. Together they make up the tiger an unbreaking forest that stretches seven thousand miles around our planet and contains 1/3 of all trees on earth.
當南方溫暖潮濕的空氣遭遇極地的寒冷,天空出現了由濕氣形成的冰晶及雪花。每一片水晶都是由灰塵粒子組成。兩者都是對稱的六邊形,但沒有兩片是一模一樣的形狀。他們的多樣性和復雜性令人為之驚訝。每片雪花都是等著春天被釋放的水。因為這個原因,雪是這些靜默森林及一切在這里以這樣或那樣的方式生存生命的源泉。一些動物,比如這頭灰色貓頭鷹,在春天萬物復蘇時出現,然后像幽靈般消失。而其他動物,就像其獵物一樣,常年在雪下隔絕上面的冷空氣。北方森林主要由季節性的游客和北極專家組成。但是卻遠不止此。他們一起構成了一個綿延七千英里的不可侵犯的森林,包含我們這個星球所有的樹木的1/3。
