I am gutted about what has happened. I guess I know the cave involved even though I've never been on the Gower, but I know about the caves there, and the BBC showed the enterence to the cave shot from within the cave, I think that is enougth for me to figure which it is.
I am also aware of the one other place in the UK where there is cave art. In both cases even if I knew the art was there, without a huge arrow on the cave wall I'd have a hard time finding it. It's just scratches, very hard to see without the right lighting and without knowing in advance where to look and what to look for. My point being that whoever is responsible for the vandalism cannot be just some intoxicated kid who gets in a cave. This is deliberate and done by someone who not only knows the cave but exactly what to look for and who has advance knowledge of where to look. What is the possible motivation? It can only be to get the cave gated. But not only that cave. Other caves in the area are going to be found to contain cave art and now they all need gateing to preserve the art even before its found.
