Nothing quite so exciting as somehow survived but a friend and I were hiking into the Gardner river from the road (NW Yellowstone NP), all rocks and crevasses, some deep. At the bottom of about a 10 foot crevasse was a good sized grizzly, it saw us and went the other way out of the crevasse. I told my friend that i was prepared to run faster than him!!!!!!!
On the upper Ruby river (Sheridan MT would be the closest town) we were hiking through some pretty wild country with same friend, we found an antelope leg poking out of a bush (most likely a mountain lion kill). Never saw the big cat but it wasn't for lack of trying!!!!!
