With winter weather pummeling the nation this week, warming up by a fire becomes more of a necessity than a comfort. But stoking a strong flame will take more than a piece of wood and a matchstick, especially when the ground is covered in ice and snow.

Thankfully, there are plenty of ways to spark a flame. Whether you have a well-stocked woodpile or are starting from scratch, follow these pointers from the survival experts at Popular Science, Field and Stream, and Outdoor Life.

1. Assemble your tools

The first item on your list should be a firestarter. It could be a strip of birch bark or a handful of Doritos—as long as it’s something small, dry, and oily, it should work. Learn more here.>>>

2. Choose the type of blaze

Seasoned outdoors people know fires have multiple uses. A signal fire, for instance, should be freestanding, while a tarp fire requires more setup. Figure out what’s right for you. Learn more here.>>>

3. Add a protective layer

To prevent the moist ground from extinguishing your efforts, lay down a “raft” of scrap metal or rotten wood. When using the latter, opt for whole pieces over split ones. Learn more here.>>>

Bonus tip: Dress warm

What you’re wearing is at least as important as where you’re getting your heat. When experts say you can never have enough layers in the cold, they mean it. Learn more here.>>>

Bonus tip: Think beyond fires

If you live in an apartment building or a shelter, starting a fire may not even be an option. When losing power during a storm, there are ways to use utilities, gadgets, and even pets to help keep you warm. Learn more here.>>>
