I just wanted to share the link to this fascinating story. Mr. Orr's experience makes the bear attack scene in The Revenant look like child's play!
Years ago, I was backpacking on Death's Head trail in the Tetons, in an area where a man had been severely mauled by a bear. The man's hiking companion went down the mountain to summon help, but before the rescue team could make it back up the mountain to the campsite, the bear returned and killed the poor guy.
The night we were there, we camped right beneath the famous Teton peaks. We didn't use our tents because the weather was perfect and the stars were glorious.
Even though it was a beautiful night to sleep under the stars, I had a hard time getting to sleep because the friend I was hiking with was a loud snorer, and all night long I kept waking up in a panic thinking we were being attacked by an angry bear. It was one of the longest nights of my life.
