If I am trying to travel light a propane bottle and torch head are out of the question. Usually I would have a pack, ditty bag and pockets. Then i would have several ways to make a fire, matches (water resistant), lighter, magnesium stick and sometimes carry paste, which is heavy but does work well with the magnesium.
I always carry something on my person and other items in the pack/bag. You never know what could happen and you could get separated ftom your gear. Food is important, but water is more important, typically water is available here in AK.
If you're up high you might have to walk, but usually it can be found.
Fire can be lifesaving as hypothermia can be deadly, I've only been in that situation once while sheep hunting and its humbling to be in that position.
