Ghosts are stirring in Colorado’s high country. These are the guardians of a delicate balance. They haunt the trees, the water, the animals – the very fabric of the land itself. Gray wolves shaped this place for eons only to disappear nearly overnight. Canis Lupus Colorado is the story of the past, present, and future of Colorado’s now extinct native wolf population. It unfolds through the eyes of Mike Phillips, the world’s foremost expert on wolf restoration, John Emerick, an ecologist and author in Rocky Mountain National Park, as well as photojournalist Morgan Heim, elk hunter David Gann, and lifelong rancher Duke Phillips. Together, these perspectives paint a sweeping portrait of the complex relationships between people and predators in the 21st century. We’re at a tipping point: the emerging west, the future of our public wildlands, and the health of vast ecosystems are all at stake. And the choice is up to us.
