Camping in the Absarokas and went down about 50 yards to the stream and got water to cook a clean up from dinner. Got up in the morning and went back to the same spot to get more water and found fresh grizzly tracks in the mud right where I got water the night before. Yeeesh!
One summer I worked in Glacier and had a buddy invite me to go spelunking with him to a cave he saw on a map. I couldn't get my shift covered, so he went on his own. They found him the next day after he jumped a sow and her cub.
