Kingdoms of the Sky

The Rockies stretch 3000 miles across a beautiful wilderness, home to cougar, wolverine, wolves, and grizzly, and where daredevil wingsuit fliers jump from high peaks and Native Americans compete in breakneck horse races.

Meet the extraordinary wildlife and people of the Himalaya--the highest mountain range on earth, where the air is the thinnest, the wind the strongest, the storms the fiercest. The higher you climb, the tougher it gets to survive.

The longest mountain range on the planet holds hidden worlds, from the driest desert on Earth to cloud forests full of life, from pumas to shape-shifting frogs. And see descendants of Inca build bridges of grass among the spectacular peaks.
