It is just common sense not to embark on tricky enterprises like high altitude, technical mountaineering alone. You increase the probability of bad outcomes significantly. I wonder how often those of us on this forum have done something tricky on our own.

I don't think I have soloed more than two hundred times or so, that I can recall offhand. Sometimes it is circumstances, sometimes it is simply the desire to do it alone, the craving for solitude, and perhaps the desire to test one's limits. After all, if absolute safely is to be the prime concern, we wouldn't go anywhere near mountains or even any outdoor venues.

The lady in this episode is a highly experienced mountaineer and i am confident she is aware of the hazards she confronted. She was well equipped for the climb she attempted.

Inevitably, the odds will likely catch up with those who take risks. Consider the recent demise of Ueli Steck, who made a career of risky solo climbs - the North Face of the Eiger, for one.
