I caught a really interesting program on TV - Man vs Wild.
http://dsc.discovery.com/fansites/manvswild/manvswild.html
The host, Bear Gylls, was dropped on top of a remote range in the Copper Canyon area of Chihuahua, Mexico - at 9400 ft (2865 m). The day time temperature was ~70+°F, but at night the temperature would drop to 15°F, so that anyone without protection would risk hypothermia.
For each 1000 ft (305 m), the night time temperature would increase a few degrees, so the objective would be to get down to the valley as quickly as possible - but the mountain sides are steep and somewhat unstable. Also, one has to be careful where one puts one's hands in order to avoid scorpions or tarantulas, and perhaps rattlesnakes. Gylls ate a scorpion that picked off the ground to indicate that they are a good source of protein.
Gylls got to about 7000 ft just before the sun went down and the temperature started to drop. He stopped and made a fire, which he demonstrated.
He used a yucca plant which was dry, and has the lowest flashpoint of any wood. He made a fire sword, which makes fire by friction. To make the fire initiator, he cut two pieces of wood and placed them in parallel with two stones separating them, and bound them with green stalks. He filled the gap with dry grass, but tinder would be suitable. He placed the sticks between some rocks, and then proceeded to rub a 'fire sword' perpendicularly across the two sticks and above the dry grass (tinder). After a few minutes a hot piece of wood lit the grass. He placed that on another bundle of grass and added some sticks.
