I am planning our Troop's annual snow camping trip for the older scouts. We usually go up to Yosemite, Alpine Lake, or Carson Pass. Snow shoe in 3 to 5 miles, build snow caves and camp out two nights.
This year there might not be enough snow do build caves. So I am thinking what else can we do. A post by Bob Gross on another tread about his annual habit of building a fire and boiling water on his first ski tour of the season, got me thinking. Perhaps we could have a fire building competition where teams of 2 or 3 scouts build fires and bring a pint of water to a boil.
Ideally, I would like to design this in such a way that it can be as leave no trace as possible. Meaning, I do not necessarily want to dig three or four holes down to mineral soil. (And leave after the exercise 4 or 5 black sooty scars in the snow).
I have seen references on the web to folks building fires on snow with "fire cloth" and/or galvanized trash can lids on top of a bed of branches. We could haul in some wood to provide insulation to avoid the need to cut wood from live trees. But I hope some Scouter has more specific ideas so I am not having to invent this from scratch.
I suppose I could bring my Bush Buddy and borrow two others from friends and have the teams build tiny fires in the Bush Buddies.
Note: Many of these Scouts passed the BSA fire building rank advancement without actually having to light the fire. So one of my other goals, it to give them practice in building a fire.
Thanks
