 Is there a strange thing high up in the world's tallest mountains? If so,is it a big bear? Is it a money? Or is it a kind of man?

   No one knows. This mystery has puzzled (困惑） the world for years.

In 1887， a mountain climber found large footprints in the snow. They looked like the footprints of a very large man. But men don't walk without shoes in the snow ！

In 1906,another climber saw more than footprints. Far off,he saw a very large animal standing on two legs. As he watched,it ran very quickly.

Fifteen years later, newspaper had new stories about the "something". A mountain climber said he had seen the "snowman" walk slowly across the snow, far below him. He said it looked like a very large man. From then on, more and more people had stories to tell. But not until 1951 did a mountain climber bring back pictures of large footprints. The pictures showed clearly that the snowman walked on two legs. Could it be an apeman (猿人)？ The mystery grew ！ Someday we may find out just what it is that makes the large footprints.
