You have followed the track towards the bottom of the valley in the hopes of finding someone there who may be able to help you find your way out of the valley. It is a long hot walk as you make your way along the track. You are very thirsty and want a drink. You remember seeing a river which flows down the middle of the valley. You know it is somewhere near the hills, so you turn towards them and walk East until you find it. There is much long grass to stagger through since there is no track leading towards the river. This grass is so long that you often find that it is taller than you. All the same, you find the river. It lets you know that it is there by the sound of rippling water running over stones in the river bed which is very near the hills. You cu your hands and take a drink of the nice clear water. It is sweet add clean.
