Steve Backshall looks for the answer to a puzzle involving wolves and beavers.

In Yellowstone National Park, where wolves, bears, coyotes, bison and elk roam vast grasslands, wetlands and forests, Steve Backshall looks for the answer to a puzzle.

In the spectacular Yellowstone where wolves, bears, coyotes, bison and elk roam vast grasslands, wetlands and forests, Steve Backshall looks for the answer to a puzzle.

The revelation is as magical as it is surprising.
