Extreme Alpinism

[Ade]

For example, the idea of taking a piece of tin and bending it over the bottom of your canister so that the ends are heated up in the flame. Does anyone actually do this? It sounds a bit dangerous but I'm sure you'd save a lot of time melting snow at high altitude or in really cold temps.

Do it every time I go out in winter, still have all my hair etc. The idea isn't new and it's certainly not Mr T's.
