The napoleon was there the first year. I can't remember after that, maybe Dan remembers if he brought it after that, i don't think so. We definitely used the camp chef last maze trip.
IIRC when I talked about about fires with the rangers their take is you can have a fire it just can't touch the ground and you have to pack out the ashes, no burying them. Backpackers have used fire pans. They noted you can use a fire pan. I had thought about a pit but don't want to deal with the ashes the next day and the propane is easier to deal with.
