National Geographic cameras capture unseen aspects of magnificent Yellowstone -- America's oldest national park and among the most visited, though only 10 percent of its massive acreage is known and traveled. Viewers journey through the ecosystem's untamed beauty to sites tourists never see, including a 20-mile-long canyon and newly discovered waterfalls. The documentary also focuses on the effects of restoring Yellowstone's wolf population.
