Regardless of any involvement of a government or any factors of corruption - I'm just purely interested in the fact that nature could sustain a fire like this in -50C weather.

Why wouldn't it? Cold (within its limits on Earth) does not affect burning, in fact it probably makes it more effective due to convection.

I am confident enough in my general knowledge that I can be interested in an article on a thing that I can rationally explain but never imagined independently. It's interesting that this fire is happening in blisteringly cold temperatures which is against my intuition as a being that feels like 110F is pretty hot and 40F is pretty cold.

Yeah pretty neat. -50F is as far from 40F as 130F is. (The absolute difference is 90 degrees F)

You're probably downvoted because it's "not relevant", but that was a good documentary. It's good to be the king, huh.
