For centuries, people reported seeing a wild creature in the Himalayas calling Yeti. The Yeti is said to be a large, hairy animal that walks on two foot like a human being. In 1998, an American mountain climber said he saw a Yeti on the Chinese side of the Himalayas, that walked like a human, but it had thick black fur and was about six feet tall with huge shoulders, very long arms and large hands. In 2007, an American TV team saw Yeti tracks 33 centimetres on length in the snow near Mount Qomolangma. Because of these reports and the tracks, there have been several organized searches for this creature, and no strong evidence for their existence has ever been found. Scientists hope that the mysterious will be solved one day. If such the creatures really exist, we might have the chance to see it with our own eyes.
