Watch Mountain: Life at the Extreme Season 1 Online

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 fliers 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.
