I asked Blaze O'Connor about that site, which, if it's the same one, is near where the Dingle peninsula meets the mainland. She surveyed most of the rock art recorded in the area and couldn't locate this one. I can check that again but I'm pretty sure. There's a lot of RA sites around there that were recorded in the late 1800's and early 1900's but subsequently could not be found again.

If you browse this site http://www.europreart.net/preart.htm many of the sites that could and couldn't be located are illustrated.
