The National Geographic Secret Yellowstone DVD brings you the viewer to places most Americans have never seen. Discover spectacular backcountry wonders unseen by tourists as you venture off the beaten track to experience the extraordinary hidden wilderness of Yellowstone National Park.
Witness towering, newly mapped waterfalls; rarely seen predator behavior by wolves and grizzly bears; and ecological mysteries found only in this uniquely challenging environment. Probe the vast molten magma chamber that underlies the park and powers its incredible array of explosive geysers, seething mud pots and toxic gas vents.
Featuring striking satellite imagery and dynamic computer-generated animation, this is Yellowstone as you've never seen or imagined it before!
