Stomp out a flat spot, protected from the wind, and construct a platform out of rocks or logs. Ideally, you'll have a large, flat stone in the center. Place your tinder atop this, and arrange sticks tepee-style around it, then light the tinder. Make sure to bring a foolproof firestarter. As a backup for your butane lighter, one of the best flammables is drier lint (or cotton balls) slathered in petroleum jelly, packed in a pill bottle.
