Also, one other fact that people don’t realise, is that using oxygen makes it sound like a cakewalk, but its not.

Your breath has water vapour in it that freezes and accumulates. So, you’re even competing with your oxygen mask getting frozen shut apparently at high altitude. At 8000m+ you need it, and to sleep at 8000m, you apparently still need some oxygen, or you gag.

Apparently oxygen bottle theft is also common.

Once you’re at 8000m (camp 4), you’re basically on your own… Yes, its a bigger accomplishment to set up camps and carry everything up, but, it doesn’t mean that even getting to 7000M isn’t a huge achievement (Everest is 8900m).

I am planning to do a 700km walk hopefully within the next year, and, I don’t think anyone is going to downplay it simply because I have done food drops (and had others helping with food drops).
