Wood or propane, it all depends on what you' re doing. If you plan on having a base camp, wood is the best for good warm your bones heat, it' s also great for drying out your clothes and what not. I agree with BJ that most decent woodstoves should go most the night. We' ve had propane in our base camp before and it' s just not as comftorable, and this is in Sept., the temp. still hits 10 to 15 deg. now and then. Now if you' re planning on packing in and spike camping it, then a small type propane heater would work well and is light enough to pack. elknut1
