Was just looking at East Ayrshire on here, it's a very unrepresented area at the moment:

But the ones site that sticks out is a very impressive rock art site. Be very interested to know what others make of your markings. What kind of rock are the stones?

The Ballochmyle carvings are amazing ... they are not really known too well even to locals - either it's for protection from vandals or as the nice woman told me as she gave me directions (got very lost) the council don't want problems with health and safely and have to pay out to install a proper path to get to see them.
I still have other things to photograph and will add in due course ... not sure of the type of rock of that particular bolder.
