Everest: an extreme environment

I've been working up some materials relating to Mount Everest -  the story has been very popular recently with the image of Nims of Project Possible and the queues near the summit.
I've been using the GeographyPods page from Matt Podbury's website once again.

The Week had a useful article on the risks that Sherpas face when they are putting ladders in the Khumbu Icefall as they spend far more time there than the climbers who pass through less regularly than they do.


I also came across the GAMOW Bag.
Look at the image here - what is this and what is it used for?
