They did say that one of them had it's north arm pointing directly at a large piece of decorated bedrock, which was covered in cupmarks, at least one of which had three rings, 'about the size of a dinner plate'.
They also mentioned that it had had some of its surface removed and re-carved. (this latter factoid might have been refering to a different place though)
They all seem to be quite close to each other from the way they were talking about them.
