Ages ago I posted a fairly epic amateur video shot in Kruger National park. Here's something similar shot near Banff, Canada. It's not often you witness an Animal Planet-style struggle off the side of the highway.
The videographer explains:
When the video starts the baby elk is about to be wounded by the wolf but gets away and some distance. Soon after hearing the baby Elk crying the grizzly bear decides to go after the baby elk and no regard for eloquence or the wolf. At the end of the video the elk gains some distance but ends up on shore with wolf waiting on the train tracks and the grizzly bear eventually catching up.
A riveting scene. Don't watch if you find the harsher side of the natural world scary, although I'm sure (cough) the elk got away.
Watch, AFTER THE JUMP...
