Kingdoms of the Sky

The Rockies are the spine of North America – a beautiful wilderness of snow-capped peaks and hidden valleys. Cougars hunt in abandoned ranches, wolverines search the deep snow for food and Grizzly bears hunt in the high mountain meadows. Daredevil wingsuit flyers leap from mile high cliffs and Native American tribes compete in breakneck horse races. It is also the range of surprises – with tiny cannibal salamanders hunting in mountain ponds and hummingbirds making enormous migrations.

The Himalaya is the highest mountain range on earth. Here the air is the thinnest, the wind the strongest, the storms the fiercest. Yet extraordinary animals and remarkable creatures do make a home here. The higher you climb – the tougher it gets and the film travels up in altitude, showing how these resourceful people and animal survive.

The Andes is the longest mountain range in the world and is home to extraordinary animals and remarkable people. There are dozens of hidden worlds in the Andes, from the driest desert in the world to cloud forests teaming with life. There are vertical peaks towering over twenty thousand feet but also the Andes is home to the flattest place on earth - a huge salt flat which has the most bizarre light show every night.
