Gizzlies by themselves are scary and powerful. But how about two grizzlies who are in aggressive fight mode? This video was taken near British Columbia by Cari McGillivray and posted on her Facebook page with the caption: "Don’t normally post on here but thought I’d share this incredibly rare and amazing moment with all you guys of these grizzlies fighting!"

They are clearly not playing. Supposedly, there's also a wolf in the video too, but we never were able to spot it.
