How to find your way if you're lost in the wilderness
This is just a few tips for if you get lost-it shouldn't be taken as an exhaustive guide, cos it obviously isn't. It is also mostly for Australia.
One of the best things to do is to go downhill. This is because water always flows downhill, carving a path as it goes. If you keep going downhill (it may be hard at times to find which way is downhill, refer to other methods then) then you'll reach a creek, which you then follow to a river, which you follow to the sea. Under some circumstances this may be hard, unwise or impossible (mostly in Northern Australia where it's all mud, mangroves and monsters.) Once you're on the shore, you follow it, usually south in Australia, cos most of our settlements are that way from wherever you are. Settlements are almost always near a water source or the sea, so this method is very effective.
It's always important to know the points of the compass-use the sun (it rises in the east, sets in the west) or the southern cross (draw a line across the two pointer stars and another through the middle of the southern cross-where they meet is south. I can't guarantee this one as it is often hard to understand till you see it done). If you have the materials and want to be exact, get a needle and run one end of a magnet along it twenty times in the same direction-this will magnetize the needle. Float the needle on a very small leaf, in still water. It will gradually align itself to magnetic North...use the sun to find which end of the needle is pointing north. This isn't very helpful overall, but if you want to know where north is, it's handy.
Lichen can also be used-it always grows on the north side whatever it's on. (Lichen is dry and flaky if you need to recognize it)
