left their base camp by a lake and stared climbing the north face of a mountain called Siula Grande in the Peruavian Andes. This climb was incredibly dangerous but the two men were experienced climbers and physically fit.On Day 1,the weather was good and tbhe climb began well.
At night they made a snow cave and slept 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 happend. Simpsom
Yetes didn't know what was happening below. He waited for an hour but the rope was too heavy and it was pulling Yates down the mountain towards the cliff. He had two choices: hold the rope but then both of them might die, or cut the rope and survive. It was an impossible decision for Yates but, at the last second, Yates cut the rope and saved himself. Immediately,Simpson fell thirty metres into a crevasse.
The next day, while Yates was desperately looking for Simpson, he found the crevasse. He called for Simpson but heard nothing. Sadly, he decided that Simpson was dead. Yates didn't know it but Simpson was - unbelievably - still alive inside the crevasse.
Simpson waited for hours but when he realised Yates wasn't coming,he decided to tack a rick. He had some rope so he realised to the bottom of the crevasse.
