Caught this by chance - the first half features a lot of interesting footage of eg 1922 Brigadier Bruce's expedition (300 pack animals and 100 sherpas) but includes lots of images of Nepalese including dancers wearing costumes of human bones.
It was the first time I had seen film of a matchlock with the inbuilt forked-rest being used.
Other footage features the 1934 "Wings over Everest" film, and the German 1934 expedition to Nanga Parbat.
Might inspire terrain making, or scenarios, for back of beyond players.
