Yellowstone is the world’s first national park—how well do you know its history? For thousands of years, Yellowstone was a place where Native Americans would hunt, fish, and forage. Today, 27 Native American tribes are closely involved in resource management and decision-making of the park. #AmericasNationalParks is now streaming on Disney and Hulu. | National Geographic History
