National Parks Collection - Season 1 Episode 1 Secret Yellowstone
National Geographic goes beyond the tourist hotspots and travels deep inside the 2 million acre national park to reveal the backcountry wilderness few have seen. Explore some of the 300 newly discovered waterfalls and learn how wolves, back after five decades of absence from Yellowstone, are helping restore the balance in the ecosystem alongside the grizzly bear and bison. Finally, discover how the geology of Yellowstone with its giant well of molten lava underneath the surface is sometimes more dangerous than the wildlife.
