Mt Whitney Zone Forums Gear Heads Cold Weather Tips for Gas Stoves

Thanks for posting that, Jim.

So you ARE saying that if you have an upright canister stove, more propane will burn off early and less butane, so over the life of the canister, there is more butane left behind, effectively raising the vaporization temperature. So once only (or mostly) butane is left behind, the vaporization temperature is pretty close to that of butane, 31F.

And the result is that the canister just wouldn't work on snow trip.

I'd take my Coleman Fuel pump type stove on any winter trip. Those will always work in the snow.
