Recommend the MSR or JetPower for cold temps and higher altitudes. Beyond 10,000 ft, liquid fueled stoves such as white gas or kerosene will give best results.

While propane does work very well in cold temps, a heavier canister is usually required for its transport making it less feasible when carried on your back.
Canisters that fit my old butane stove are no longer made. It used straight butane and it did give me some problems. In the cold, it wouldn't get hot enough to do anything.
