Chloe and a wall

People often look at Lake District walls and wonder what on earth they were built for, especially if they are aware of the fact that the sheep have their own heafs (see my Herdwick blip last week). In fact the walls are less to do with animals and more to do with man.
When the Enclosure Acts broke up common grazing and allocated it the walls were needed to give physical evidence of bounderies. This wall would perhaps have sperated the lands of two villages as there is was a village in the valley on the right.
Some of you will now have worked out that we are above Mardale, the village which was drowned when Haweswater was extended to make a reservoir.
