in may 1985 two climbers, joe simpson i and simon tates,left their base camp i by a lake and started climbing the north face of a mountain called siula was incredibly dangerous but the two men were experienced climbers and physically fit. on day 1,the weather was good and the climb began well. at night they made a snow cave and slept on the side of the mountain
three days later, after some very difficult climbing and bad weather,the two men stood at the summit. Unfortunately, the weather was getting worse so they didn't stay long. as they were going down a mountain ridge,a disaster happened. simpson fell and broke his knee. Quickly, yates tied a rope to himself and then to his friend. he began lowering simpson down the mountain and, for hours and hours,yates helped simpson get down the mountain. they were getting close to the glacier at the bottom of the mountain but suddenly simpson slipped . this time he went over the edge of a cliff, he was hanging in mid-air. simpson shouted up rotates, but the wind was blowing loudly and yates couldn't hear him.
