🔥 Fire
Make fire, keep it alive, and put it to work — the single biggest branch point in the whole tree.
Gather tinder and firewood
Collect the fluffy dry stuff that catches a spark, and sort wood from thin sticks to thick logs.
Make a safe fire pit and lay a fire
Clear the ground, ring it with stone or bare earth, stack tinder and sticks so a tiny flame can grow, and know how you will put it out.
Start a fire with sparks
Strike sparks from hard stone and steel into your tinder and blow the glow gently into flame.
Make fire with a bow drill
Spin a wooden stick with a small bow until the rubbing makes a glowing ember, then breathe it into flame.
Keep a fire day and night
Bank the coals at night, wake them in the morning, and carry a wrapped ember to a new camp so you never start from zero.
Cook food over fire
Roast food on sticks and hot stones so it is safe to eat and tastes good.
Cook in a pit oven
Bury food with fire-hot stones and let the ground bake it slow and even while you work.
Make charcoal
Cook wood slowly with almost no air so it becomes light black fuel that burns far hotter than wood — the key to lime, glass, and metal.
