Abominable Snowman
The Tibetan YETI, a mythical monster supposed to inhabit the Himalayas at about the level of the snow line. Though reports of actual sightings of such a creature are rare, certain 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 certain gaits bears place the hind foot partly over the imprint of the fore foot, thus making a very large imprint that looks deceptively like an enormous human footprint positioned in the opposite direction.

Sasquatch
Sasquatch is variably described as a primate ranging from 6 to 15 feet (2 to 4.5 m) tall, standing erect on two feet, often giving off a foul smell, and either moving silently or emitting a high-pitched cry. Footprints have measured up to 24 inches (60 cm) in length and eight inches (20 cm) in width. A Soviet scientist, Boris Porshnev, suggested that Sasquatch and his Siberian counterpart, the Almas, could be a remnant of Neanderthal man, but most scientists do not recognize the creature's existence.
