Fire On Snow

The weather was perfect and I needed to get out and stretch my legs! What better way to do that than snowshoeing and a little bit of winter woodcraft practice?
A little scrap of birchbark, a convenient bone-dry dead tree, and a ferro rod were the ingredients for a spontaneous fire, served up a cold layer of crunchy snow. It's been too long since I've started a fire that way, so I wanted to increase the challenge by not pre-cutting firewood from the tree and by building on top of the snow. Remember, all the internet "experts" say that you need to make a platform to build the fire on so that melting snow doesn't put it out! One small fragment of bark to set tinder on couldn't possibly do the job, right?
As a bonus, watch for the moment I jab a pointy stick into my thumb on camera. It bled fairly good for a bit (off camera) but I was able to eventually get it to stop simply by rubbing it in fresh snow repeatedly.
