"Compare the quality of information in the ERA report , something described by you as a fiasco ,with your judgement based on no knowledge or experience of the subject and some pics just clear enough to show the markings are natural ."

I'm sorry, love, but you're just going to have to stew. 'A little knowledge is a dangerous thing'. When you demean and insult drystone wallers you show that you are empty of humour and kindness. I suggest you get out of your armchair and visit this valley. Not to the demented carved stones, but to the copper mine or the roundhouses that have been split by the latest road. Then your criticism will have a genuine basis rather than being a bullying personal attack.

There are several stones with simple cupmarks, at the Knar, and it is an utter fiasco that these weren't surveyed in any way, shape or form. Nothing will change that!
