Am Fear Liath Mòr (also known as The Big Grey Man of Ben MacDhui or simply 'the Greyman') is the name of a presence or creature which is said to haunt the summit and passes of Ben MacDhui, the highest peak of the Cairngorms and the second highest peak in Scotland. It has been described as an extremely tall figure covered with short hair, or as an unseen presence that causes uneasy feelings in people who climb the mountain. There is little evidence of the existence of this creature besides various sightings and a few photographs of unusual footprints
