Do not panic, take your time and concentrate and you can build the fire that you want. In rain or snow, fire making becomes more important, and also more difficult. One method is to make a tripod of sticks over your chosen fire area and drape your jacket over the tripod to shelter the fire base. Carefully light your tinder, add some twigs, and remove your jacket. If the ground is exceedingly wet, lay a base of large logs and sticks and start your fire on top of them.
Dry cones are great too.
You may not have the time or the energy to go around and select wood, so burn what you can, get warm and safe and then look. Just remember that pine, cedar, spruce will start a fire quickly but burn swiftly . Woods such as oak, ash and maple will burn longer but are more difficult to ignite . Aspen, birch and poplar are quite common and they make good fires as they burn hot but fairly fast . Solid Fuel Tablets are an excellent long burning and hot ignition source for use as fire tinder.
