"That guy is an epic generator..." Agree.
However, I would call this an unfortunate tragedy rather than an epic; OK, for one a tragedy and for another one an epic (because, despite of the experiences and conditions he was dealing with, he was still able to get out of the mountain, and most importantly, on his own). Perhaps the survivor was preconditioned by his previous events, or perhaps by the way his mind works in such situations.
All sort of High Altitude Sickness is very common on Mt Shasta just not at that magnitude and death usually takes climbers by a surprise even though it does not strike like a lightning. The chain of decisions before the realized symptoms and after sets the trajectory to the final outcome. Summit fever, ego and denial besides not understanding the symptoms and possible consequences are very crucial cofactors leading often to tragedy.
Fortunately that sickness is not a leading factor of death accidents in the US mountains (not sure about Alaska). However, it cannot be completely excluded as a factor leading to other accidents. Mental or physical discomforts prone a climber to making imperfect decisions and other mistakes.
The bottom line is, regardless of one’s point of view, it was an incredible mountaineering experience.
Any other stories some may not be aware of?
