Here's some photos of a Mors Super shelter Hammock style done with a
simple DIY 6 sided tarp made from one sided reflective nylon material with added pull outs and 12' x 12' 2 mil poly plastic. Folding bow saw to cut wood.
Outside temp is 10*F, wind 10 mpg from the NW, in side temp is 60*F plus and cozy. Simple easy setup.
You would burn less wood then if you where trying to warm yourself or dry clothing with an open fire in the cold. No smoke problems.Can dry clothing on ridge line.Cook on fire , melt snow for hydration needs. Depending on the type of fire lay possiple to have 2 hour + burn time with out tending fire.
With finnish fire lay up to 6-8 hours.
Done properly you would leave no more trace then if burning a campfire.
The more you know the less you carry.
