This stone was dug out of a field from a depth of around 1m during field clearance a few years ago. It measures about 1m x 0.5m x 0.5m and has carvings on one face. It now resides in a garden border opposite the backdoor of the lady who owns the field where it was uncovered. It is only available to view nowadays due to the insistence of this lady, who stopped it being reburied. The condition of the carvings indicates that the stone was exposed for a long time before becoming buried.
I visited during the afternoon while the sun was shining brightly - a big mistake as the carved face now faces south. I managed to get some of the carvings to show up using side-flash when the sun disappeared behind cloud.
The motifs are spread right across the whole surface and are mainly cups with single rings around them. The cups are quite small and the rings are around 10cm in diameter.
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.
