Gray wolf attacks elk in river in Yellowstone National Park, another way wolves change rivers.

A gray wolf attacks an elk in the middle of a river in Yellowstone National Park.

This dramatic footage of a wolf-elk encounter was captured by B&C Chief of Staff Tony Schoonen in Yellowstone Park over the weekend. Note how the wolf cleverly removes an obstruction in his way.

We don't know the final outcome because a park ranger asked everyone to move along.
