In 1925, the noted climber J. Norman Collie recounted a terrifying experience he had endured while alone near the summit of Ben MacDhui some 35 years before. "I began to think I heard something else than merely the noise of my own footsteps. For every few steps I took I heard a crunch, and then another crunch as if someone was walking after me but taking steps three or four times the length of my own." Collie was unable to make out the source of the noises because of mist, and continued "... the eerie crunch, crunch, sounded behind me, I was seized with terror and took to my heels, staggering blindly among the boulders for four or five miles."
