Burning a fire on top of the snow is often one of those things that you never really think about, until you have to do it. In areas with little snow, you can always dig down to the soil surface to build your fire. But if the snow is very deep, or you lack digging tools, fire on top of the snow is the best option. Less experienced outdoor enthusiasts often get a rude shock the first time they try burning a fire directly on the snow. The fire starts out normally enough. Then the snow melts, which puts out your coals and leaves you with no fire and a jumble of wet, black sticks. To solve this problem, you're going to need a platform. This can be a manmade material such as a piece of metal for a platform. You'll just need some logs or rocks under it, so the metal doesn't melt the snow underneath. If you don't have metal, the platform can be made of dead wood, rotten wood or green wood. This last choice is the best, because the live wood has enough moisture in it to keep it from burning for a few hours, but not so much moisture that it puts out your burning sticks or bed of coals. You can use whole chunks of wood, or split the wood in half to create a very flat platform. Obviously, the whole pieces will last longer than split wood. Replace the raft as needed.
