At the end of a long (for me) two summit hike in the White Mountains (New Hampshire, USA) I was traversing along an okd railway line back to the trail head when an adult black bear emerged out of the forest onto the railway line about 50 yds ahead. I turned and walked away as quickly as possible.railwayThe bear strode across the railway and went into the woods on the downhill side. I usually relish wildlife encounters on a hike, and this year have spotted moose and fox, but this one I only relished in retrospect. At the time i was more concerned to fet the hell out before it registered me as a threat. About 1/2 hour later, an adult bear was reported crossing the main road running parallel to the the railway about a mile below.
