Ok, given the objects above, minus the matches, I could make fire a couple of ways. My first attempt would be to use the reflective surfaces of the flashlight (glass lens, parabolic cone, etc)combined with tinder. A sunny day would be critical. The process would be the same as starting a fire with a magnifying glass. If that did work, I would construct a bow drill. I have a knife to carve all the necessary parts. I would use a shoe lace for a string, soft wood for thehearthboard and bearing block, a willow for the bow,and hard wood for the drill/spindle. I sure I could find something to serve as tinder. I could also use the batteries from the flashlight. I would gently break the glass on the flashlight's bulb exposing the bulb's filament-risky I know, but it would serve as a last effort. The filamentcould be gently held against fiberous tinder which would ignite instantly. I'm gonna give this one a try in the off season. I know 100% I can start a fire using the bow drill...

Do you know you can start a fire with a chocolate bar and a pop can?

As far as shelter, how hard is it to stack rocks and chink them using grass and mud? A simple shed roof will suffice. Downed timber would serve asthe supports for theroof with grass and mud applied over top.It's done everywhere in the world.

Panic kills people. The trick to survival is keeping your head and solving the problems as they occur.
