Extreme Survival

S1 E2: Halfway down central South America’s Andean mountain chain, nearly 13,000 feet above sea level, sits a 600-mile-wide plateau. In this vast landscape, air is dangerously thin, water is scarce, temperatures swing wildly from night to day, and only the most exceptional of animals survive. Explore life in the unpredictable Altiplano, from a caustic red-hued lake to sprawling salt flats to one of the driest deserts on Earth, and discover the remarkable creatures that, despite the odds, thrive in this life of extremes.
