Yeti, or abominable snowman, has been seen in Tibet since 40 century BC. Sightings go that it is 8 ft tall, covered in whitish grey hair and as swift as a horse. Since it's first sighting back in 1832, many more sightings of this creature fallowed, one said that it fallowed US moutiaineer, David Sheppard up Mount Everest for several days in 1984. The main evidence of the yeti's existence was giant footprints in the snow. About as big as it's cousin, the sasquatch.
