Episode 7: Andes: The Dragon's Back
The Andes is one of the world's most spectacular mountain ranges with one of the richest environments on Earth and a diverse and unique mix of plants and animals existing nowhere else in the world.
Andes: The Dragon's Back so named because of the spines along its ridge travels through this range of mountains stretching from Cape Horn to the Equator, uncovering the largest ice field outside the poles, the Torres del Paine mountain region and the Atacama desert.
