Always nice to know what happened so that we can try to learn with having to gain (experience) the hard way.
As the guy is there to tell what happen, a lot of knowledge can be learn. To avoid people to learn the hard way is really the mentality of accident in accident in north american mountaineering.
I remember that I went on shoestring with Base and led the steep pitch. Not paying attention because it look too easy, I plant my first ice axe in ice. than I step on my right foot in the same time that I pull my other tool to pick it higher. The ice blow on my first and second tools and i begin to felt. My left crampon enter in a jesus crack...and stop!!! At minus some thing, better to go up.
I am not the only one who was too selfconfident and make a mistake. Maybe it is what happen to the guy, but we can't learn from no information. In anam, a guy told that he climbed a 5.10. at the end, it was a pitch of 5.4. it was a warm day and he was just thinking at the beer that he would take at the camp. He didn't even know what happen when he felt. He sustain a broken harm.
So, I hope that we are going to know by the guy what happen... and at the ice festival, that we will see more guide training to have good technique for crampon instead of leading hard stuff.
