You must have walked further into the forest than you thought as all of a sudden you leave the trees behind and are out in the open. The moon is shining brightly and you can see quite clearly that you are standing high up the side of a hill. In front of you is a large expanse of open moorland covered in a layer of fresh snow. The moorland dips down into a valley. Presumably it must have fallen while you were in the woods where you wouldn't have noticed it as much. What ar you going to do? There's no point trying to get back through the forest as you have no idea which way you came, so your options are:
Walk towards the valley.
Or
Try to find somewhere warm to hide until the morning.

Which will you do?
