Thanks for the reply.. the main picture in the article looks significantly harder than 5.9+ to my amateur climber eyes, I'm not sure if there person above realizes 5.9+ is a specific rating in some places and 5.9+ doesn't mean 5.10, 5.11, 5.12, etc..
Ice climbing is straight nuts no matter what, even if you don't do it at high altitudes with no O2.
Climbing sheer faces with no Oxygen at that height is just literally bonkers.. hard to believe anyone who doesn't climb can even fathom that.
This climb is so outrageously impressive compared to the silly "race to climb all the 8000M mountains but the Sherpas haul everything up and set up ropes for you and maybe pull you up the mountain" stuff that has been in the news lately.
