It is a real mountain. You can't take it for granted. Many years ago one of my friends was one of only a handful that survived a school climb when near a score perished
on Mt Hood.
Even the rescuers going in and knowing the conditions of the storm (-50F
windchill) couldn't wear enough clothes and had to hole up.

To be critical
of the climbers at this stage seems to me talking in ignorance.

Fast and
light is often safer in mountaineering. If the climbers managed a good
snow cave they could be safe for days, though the north side is technical
ice and rescuers will have a tough time getting close without good weather.
