Iceland: Earth, Air, Fire and Water

Known for its arid steppes, skilled nomadic horsemen and Genghis Khan, a visit to Mongolia feels like a trip back in time. At the annual Naadam Festival, contestants vie to be the victor in the centuries-old pursuits of wrestling, archery and horse-racing. In episode twelve, Art Wolfe pursues prehistoric wild horses as they roam the steppe, rides in the mountains with a Kazakh tribesman who hunts with golden eagles and catches up with nomadic reindeer herders at their summer camp near the Siberian border.
