The Abominable Snowman, or Tibetan Yeti, is a mythical monster resembling a large, hairy, apelike being supposed to inhabit the Himalayas at about the level of the snow line. Though reports of actual sightings of such a creature are rare, some mysterious markings in the snow have traditionally been attributed to it. Those not caused by lumps of snow or stones falling from higher regions and bouncing across the lower slopes have probably been produced by bears. At some gaits, bears place the hindfoot partly over the imprint of the forefoot, thus making a large imprint that looks deceptively like an enormous human footprint positioned in the opposite direction.
