Wolves Chase Bull Elk in Yellowstone [WATCH]

File this under survival of the fittest. Doug McLaughlin, who works for Optics Yellowstone, posted this video to Facebook on Saturday. It is a video of the Lamar Canyon wolf pack in Yellowstone chasing down a bull elk. I have never personally witnessed anything quite like this.

Just a fair warning. This video is not for the timid. In my opinion, this is one of the many wonders of nature. It's crazy to think that this is just a little over an hour away from Bozeman.
