They are the sort of friends who are so close they trust each other with their lives.If one falls, the other is there to catch him.

They are Wellman, whose legs were permanently injured nine years ago in a rock-climbing accident and Corbett, an experienced rock climber. Together, they climbed up Half Dome. the famous 2,000-foot rock in the Yosemite National park, through one of the most difficult routes(路线).

During the climb, Corbett took the lead, hit in the metal spikes (尖状物)that guided the ropes and climbed up. Then, after Wellman pulled himself  up the rope, Corbett went down to remove the spikes and climbed up again. This process was repeated time and again, inch by inch, for 13 days Wellman’s job was not easy either.  He got himself up the rope through upper body strength alone. In all, Wellman figured(计算) that he had done 5.000 pull-ups up the rope on the climb.

However, when the two men first met, they never talked about climbing. “He knew that was how I got injured.”Wellman said. Until one day Wellman decided that be wanted to climb again and they started training

Their climb of Half Dome was not all smooth. At one point, pieces of rock gave way, and Corbett dropped down quickly. Wellman locked their rope in place, stopping the fall at 20 feet. His quick action probably saved his friend’s life.
