I've actually looked for this site before. In fact, I've walked right past it. My excuse for not seeing it is that I thought I was looking for a bullaun stone at the time, not a cup-marked stone. When the farmer described the stone to me it didn't sound like a bullaun - he mentioned lots of small dents in one side - so I was on the look out for something else this time.
The large stone (1.5m x 1m x 1m) lies at the edge of a small pile of field clearance. The cup-marks are spread over the outer, upright face of the stone. I counted at least 11 cup-marks.
I had to go back to the car to fetch my GPS to record its position. When I did so I left my camera there. I then had to go back to get the camera when I noticed a large cup in the end face of the stone. I presume this is why it was classed as a bullaun stone in the first place.
To have a bullaun on the end of a stone and cup-marks down the side of it is most unusual. Again, this looks like a rare crossover and link between rock art and bullaun stones.
This is an explanation of (and a bit of a disclaimer for) the coordinates I provide.
Where a GPS figure is given this is the master for all other coordinates. According to my Garmin these are quite accurate.
Where there is no GPS figure the 6 figure grid reference is master for the others. This may not be very accurate as it could have come from the OS maps and could have been read by eye. Consequently, all other cordinates are going to have inaccuracies.
The calculation of Longitude and Latitude uses an algorithm that is not 100% accurate. The long/lat figures are used as a basis for calculating the UTM & ITM coordinates. Consequently, UTM & ITM coordinates are slightly out.
UTM is a global coordinate system - Universal Transverse Mercator - that is at the core of the GPS system.
ITM is the new coordinate system - Irish Transverse Mercator - that is more accurate and more GPS friendly than the Irish Grid Reference system. This will be used on the next generation of Irish OS maps.
