Wanda Rutkiewicz wanted to be the first woman to climb the three tallest mountains. She made the first two but couldn't survive Kanchengua. It is said that she was mentally weakened as she tried to make the suggestion whether to go down or considering to keep going on. She decided to keep going but that decision cost her her life. She had climbed 9 mountains that are 8,000 meters are over. This would've been her ninth. The bodies of the people that she was travelling with have been found but hers hasn't. She died around May 12 1995.
More recently, is the story of Weidlich. She successfully made it up the mountain but she was abandoned on the way down the mountain. She was complaining of her eye beintg really strained and sore and she was starting to lose her vision. She also managed to damage her right knee. Therefore, the Sherpa's couldn't wait for her to continue their descent. I don't agree with leaving a anyone to die. However, they probably that she wasn't going to survive much longer and that she would hardly make it down another 100 meters.
The Sherpa's have to judge if they believe the person has enough energy and will power and strengthh and endurance to make it down. However, they sometimes make mistakes and I'm not certain if this was one of the mistakes that they made.
