On January 12, 1995 wolves returned to Yellowstone, 50 years after their extirpation. Mollie Beattie, director of the US Fish and Wildlife Service, carried the first Canadian born wolf into The Park’s experimental acclimation enclosure, Alpha Female Wolf No. 5. From that day forward, their lives would be forever connected. This is the true story of Mollie’s Pack and the Lost Wolves of Yellowstone.
