Imagine this: you're on a ridgeline overlooking the Lamar Valley. Next to you, a wolf biologist whispers, "Look down there." As you peer through your binoculars you see a pack of wolves on the move. This is just one scenario that the Yellowstone Park Rangers experience daily and you can follow the Rangers as they face multiple challenging tasks of maintaining the most famous of the national parks and struggle to maintain the balance of nature. Their work is not without risks as the lolng-dormant forces of nature begin to awaken and the Rangers must fight for their own survival and that of the visiting tourists.
