National Geographic - Untamed Americas - Outside the concrete jungles and just minutes from our own backyards, another world is fighting, thriving, and surviving. Witness the elegance, power, and speed of a world rarely captured in National Geographic's 4-hour miniseries event focused solely on the Americas. Scaling mountains from north to south, crossing harsh, dry deserts, trekking through forests and circling the coasts, Untamed Americas takes a fresh look at life, death, familiar creatures and scientific revelations. Featuring rarely-filmed animals and never-before-seen behaviors, Untamed Americas presents the great outdoors just outside our own backyards as you've never seen them before.
