One for fans of shows like Planet Earth, this documentary series reveals the extraordinary animals and remarkable people who live on the iconic mountain ranges of the world. Stunning photography and the latest high-speed-camera technology were used to create the series, the first episode of which airs tonight. The Rockies, which run for 3,000 miles from the southern United States to the edge of the frozen north of Canada, have snow-capped peaks and hidden valleys which provide a home for the grizzly bear, wolf, bison, and elk. The Rockies are also home to people such as daredevil wingsuit fliers and Native American tribes.
