      Is there something strange high up in the world's tallest mountains? If so, is it a big bear? Is it a monkey?

Or is it a kind of man?

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

      In 1887, a mountain climber found large footprints (脚印) 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 footprints. Far off, he saw a very large animal standing on two legs. As

he watched, it ran very quickly.

      Fifteen years later, newspapers had new stories about the "something". A mountain climber said he had seen

the "snow man" 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. So it was not a

bear or a monkey. Could it be an ape (猿) man?

      The mystery grew! And the mystery keeps growing. Someday we may find out just what it is that makes

the large footprints.
