I've read all the books on the 1996 Everest season - "Left for Dead," "The Climb," and "Into Thin Air." All great reads and in order to get a true sense of what it was like, you have to read all three of them...also check out the film "Everest" which was originally done for IMAX and can be found on DVD. The film was done by MacGillivray Freeman.
you left out a few:
Lene Gammelgaard "Climbing High"
Beck Weathers "Left for Dead"
Matt Dickinson "The Other Side of Everest"
Cathy O'Dowd "Just for the Love of It"
Ken Vernon "Ascent and Dissent"
David Breashears "High Exposure"
Broughton Coburn "Everest, Mountain without Mercy"
Kenneth Kamler "Doctor on Everest : Emergency Medicine at the Top of the World: A Personal Account of the 1996 Disaster"
For quite a long time, I was transfixed by the events of 1996, and was involved with discussion groups that parsed everything written about it. I've met with Jon Krakauer, Beck Weathers, Lene Gammelgaard, Goren Kropp (prior to his untimely death), Ed Viesturs (for whom I'd arranged a speaking tour sponsorship) at length, and David Breashears.......all of whom were on the mountain that day, and corresponded with Sue Thompson, Bruce Herrod's girlfriend.
I'm not sure that I want to go back over the ground that I covered for several years, rehashing the opinions that I'd formed after the above. I'll just say that there is still a lot of info that has not been disclosed, and that it is complicated.
I will say that one of the upshots of Krakauers book, was that some practices on the mountain have changed somewhat, such as the practice of some guide companies of accepting people that they know have no chance of summitting, and not ordering O's for them....although charging for the supplies that don't exist. Krakauer exposed a number of "dirty little secrets" of the elite mountaineering community, and he got slammed because of it (although it was not discussed directly). He was functioning as a journalist on that mountain, and had an experience much like some journalists experience in war.
