This is the alpha male of a wolf pack in the area. They recently made an elk kill just out of the frame. This morning, the wolf attempted to take an elk leg back to the den. While en route, the grizzly intercepted and stole the elk leg. Then the bear spent the rest of the day tracing the scent trail back to the kill site, and this moment followed. They were pretty evenly matched since the bear was so young. You may notice the collar on the wolf, he is collared by the YPS and numbered 755M.
