Spending time in the outdoors can be some of the best days of your life, that is if you're prepared. Having the skills to make a fire in wet conditions will help prepare you to be one step ahead of the game, and could mean the difference between life and death.
When venturing outdoors always prepare, and have a plan, it's a good idea to always carry at least three sources to start a fire with, here they demonstrate carrying a lighter, matches in a waterproof container, and a ferro rod and striker.
Next prep an open planned out site to start your fire and establish some kindling or fire fuel.
This example utilizes birch bark, fat wood (standing pine that was dead) from their surroundings, as well as a commercial fire starter such as Wet Fire and a cotton ball soaked in vaseline that they carried in in their packs. But other examples of fire fuel include pine cones, pine needles, pine resin, dead standing plants or twigs. In wet conditions it is better to gather standing dead items then items off the ground because they are more then likely saturated.
Choose your kindling choice, and light with whatever method you prefer.
Once you have a flame going, begin to add tinder ranging in sizes from cocktail straw, to a normal drinking straw or pencil, then on to thumb size and then gradually bigger from there.
Collecting the tinder and whittling it to size is easy to accomplish with the use of a folding saw and fixed blade knife, or have them both in one awesome Survival Knife. Be prepared though, this will take some time.
Your fire can be built on the inside of a large piece of bark, or if in extremely wet conditions build it on a hardwood platform like the picture below. This will add oxygen flow to your fire which increases combustion, and will extend the burn time of your fire.
In addition to the platform, building a perimeter with bigger branches will help shield your flame, and dry out your wet wood when building your fire, while also not being as prone to collapsing as a typical teepee style.
Once you have a flame established, continue to add fuel to your fire, once again increasing size as it progresses.
Remember that your goal in wet conditions is to establish a solid foundation of hot embers, and you can never have too much fire wood on hand to get you through the night or whatever situation it is your facing, so take the time to gather and prep for these things.
Don't get discouraged, fire making especially in wet conditions is a learning process! Be prepared and have patience! Happy trails.
