Everest is the highest and certainly very dangerous, but there are plenty of others more dangerous. I've never been into that type of climbing.
I read about another mountain in that area with a 3000' shear face. It took 2 days to get up it in the best of conditions. In the article I read, there were 2 teams climbing it at the same time, Americans and Germans. They were all about 1/2 way up when a nasty cold front came in. The Americans went back down. The Germans bedded down for the night in hammocks. It got super cold and that night the Germans all froze to death.
