Tip to all *Always carry a butane lighter when in the woods*
That's what I go by, I know all you smart backpackers follow regulations, and all your guides, but this should work too. No need for fire steel except for action shots. Anyways, here's how to start a fire in the rain.
Step 1: Tinder
*Pine needles- Pine needles can start a fire easy in rain because they don't absorb a lot of water and can be easily dried.
*Bark- Dry bark is found one the dry side of the tree (as you can see with the picture above). The under side of the bark you can scrape some powder off for some good tinder.
*Shavings- You can get wood shavings from inside of a (wet) stick by shaving the (wet) bark off for tinder.
Note~ I have learned to keep all of your findings in a bag or pouch in the inside of your jacket to keep it dry and to keep it warm to almost help dry the wood.
Note~ Birch bark burns wet because of the oils in it. You could really make a whole fire on it if you are able to find some.
