Stan calls them micro-cups actually - they are tedious but there's several of them. Mainly in one field. I'm to survey them this summer with a GPS unit, if all goes well, under a local development grant. The secondary surveyors (trained volunteers) can then decide whether they are natural striations or what not. To suggest that a stonemason doesn't know stone is very offensive (but then I'm watching how the Bosnian pyramids pan out and there was a notable letter to The Times yesterday). As we say in Bolton 'if you've not got it don't knock someone that has got it'.

Closer to the White Rose county - what do you know of the Aiggin Stone ? It seems to be a county boundary stone and is italicised on the O.S., so must be listed somewhere. I have a 1" map of Blackburn/Burnley but it's on the sheet to the south.
