Holy Sasquatch! Thats bordering on the insane...

You've just reminded me of something thats been in and out of my head for months, Martin Byrne gave a leture in DCU on astronomy, tombs and art and he had a few slides of a massive triangular shaped rock outcrop with a huge number of carvings on a sloping surface which he said faced towards Croagh Patrick. He also said he witnessed the sun rolling down the side of Croagh Patrick from the same spot but I can't for the life of me remember the name, its obvioulsy out west and I presume its around Sligo/Mayo and I seem to recall it was near a built up area. It looked very similar to that one in Fermanagh, and was at least as impressive.
