     Five Canadian climbers were saved yesterday, after they spent five days high up on K2. K2 is the second

tallest mountain in the world.

     Mount Zhu Mu Lang Ma is the first tallest mountain in Xi Ma La Ya mountains. K2 is in the Xi Ma La Ya

Mountains, too. Mount Zhu Mu Lang Ma is taller, but many climbers feel that K2 is the most dangerous

mountain to climb. The top of K2 mountain is very steep (陡峭的), and the weather change very quickly.

     The Canadian climbers were trapped on the mountain last Tuesday. That morning, the weather was sunny,

but in the afternoon it suddenly started to snow. The snow went on falling for the next three days. The

climbers could only sit in their camps, and hoped that someone could come to save them.

     "It was so cold that evening." said Den, the leader of the team."We had to stay close together to keep

warm. It was teamwork that kept us alive."

      However, Den and his team want to start climbing K2 again soon."We hope to climb K2 again next

summer. We'll keep on trying until we make it."
