In the valley of the wolves: The Druids are the most celebrated wolf pack in North America. For almost a decade, they have held the Lamar Valley in northern Yellowstone. The valley is prime winter grazing for thousands of elk and thus the most coveted wolf country in all the Park. After reaching the astonishing number of 37 members, the largest wolfpack on record finds itself in trouble as the Druids begin to decline. Their leaders are failing with age and new packs are crossing their borders looking to claim the valley. This is the three-year story of the fall and rise of the most famous wolves in America, their battles against rival wolves to hold on to their beautiful range, the dramatic twists in fortune that banish them from their valley, and the perservance and evolution that bring them home at last.

Christmas in Yellowstone: A breathtaking look at wintertime deep within America's first national park, Yellowstone. Follow the trail alongside photographer and writer Tom Murphy, who has been coming to Yellowstone for the past 26 winters to camp, take photographs and experience the solitude of the park.
