National Geographic - Untamed Americas (2012) Part 4 Mountains
Untamed Americas
Outside our concrete jungles, beyond the strip malls and just minutes from our own backyard is another world that is thriving, fighting and surviving. Brawny mountains, burning deserts, tangled forests and curvaceous coasts. A grizzly bear takedown of helpless elk calves in Yellowstone. Big horn sheep going head-to-head in battle. Giant Humboldt squid cannibalizing their kin. Mountain lion cubs hunting solo for the first time. The landscapes and wildlife of the Americas are savage, shrewd and stunning. These are the great outdoors, our wildest frontiers - our Untamed Americas. National Geographic`s four-hour mini-series, Untamed Americas, explores some of the greatest wildlife spectacles and against-the-odds fights for survival in the continents` mountains, deserts, coasts and forests. Narrated by actor Josh Brolin.
