From time immemorial, Native Americans have regarded the lands now called Yellowstone and Glacier as significant and sacred. Today, nearly 30 tribal nations maintain official ties to these national parks, and many tribal leaders consider ongoing Native involvement in these areas necessary to the long-term health of America's endangered indigenous cultures. In BEFORE THERE WERE PARKS: YELLOWSTONE AND GLACIER THROUGH NATIVE EYES, narrated by N. Scott Momaday, more than a dozen of these leaders and experts from across the region offer a respectful introduction to the knowledge that tribal people here have passed down for at least the past 12,000 years. Viewers discover why Glacier and Yellowstone are so important to American Indians -- for reasons far beyond their recent status as National Parks.
