My disgust is with the posse that was with him and left him behind. I would have thought that at the first signs of serious illness several of them would have turned around with him and started back down.
But thats just me and I don't climb mountains.....
Sharpe went up by himself, without bringing enough Ox for backup. He was probably the last one to head down that day. He went down and stayed up there overnight and froze. You can't stay up in -22F, 0.3% Ox overnight. You freeze solid. When these folks found him, He could only move his eyelids
Sharpe was well liked and the other folks are always lending aid. They also know when nothing can be done.
