Long, but interesting, and very sobering.....

HAPE at 10,000 feet is very unusual, but people vary markedly in their reaction to altitude. HAPE is much more likely at 15,000+.

My take away from the video was the utility of the Inreach, and the nice low key helivac by the NPS. Yea NPS! (an old retired NPS geezer couldn't resist that.)

The mantra is "climb high, sleep low". Ascend gradually.
