I was eye to eye with a grizzly last summer. He was eating the head, legs and hide of the moose I shot the day before. I stopped my ATV, saw the bear, made eye to eye then got the hell out of there. We went back the following day to look at what he had done to the parts only to find nothing but bones licked clean (the head weighed at least 50 pounds, the hide was another 60 or so). Here's a pic of the lower jaw of the moose.
His shit was at least four inches in diameter and all over the place...fucking big bear.
