A little background from Wikipedia for folks like me who never heard of them before. The Russians call them ненцы, there are only about 45,000 of them, and they live in the far north of Russia, on the Ob and Yenesay rivers. (The Ob is the one that Soviet engineers imfamously spent decades planning to reverse the northward flow of, scheming to run it south to replenish the Aral sea. But they never actually did it.)
At the risk of sliding from 'permaculture' to 'culture' to 'Landon's Idea of an awesome freya's day night' Here is one more video on the Nganasan. This one is all in Russian and is a modern half hour spot documenting these peoples attempt to preserve their ancient beliefs and culture. I do not speak Russian fluently but it is clear that they have had their fill of Christian missionaries. Which is exactly how the indigenous people of the Yarapa basin in Peru felt. Similar circumstances I guess.
They practice a form of Shamanism and I am shocked at the similarities in some of the customs between Siberia and North America. It speaks to a very long tradition indeed.
