Hamza asked me where East was so that he could site his hide appropriately for the dawn light.
I don't have a smart phone with GPS and the compass was in my back pack. so where was East?
It was three days after the new moon, so a crescent moon was visible. It's a little blurred in the photograph because the camera was hand held.
You can use the moon to find South and if you can do that you can fnd East very roughly but well enough for the direction of sunrise.
After the new moon the sun and moon are not together and the moon must be East or West of the sun. In Northern latitudes,if you draw an imaginary line between the two horns of the moon and extend it to the horizon, the point where your line meets the horizon is South of your position.
Give it a try some night and check it with your compass, it might save your life if you are lost in the bush. Of course you have to be able to see the moon, it won't work with an overcast sky or in a woodland of tall trees. Always carry a compass!
If you disagree with my reasoning add a comment.
