When you first see this huge boulder it is a little disappointing. In direct sunlight none of the motifs show up, but with application of a little water the large collection of single cups and cup and ring devices comes to life.
The stone stood inside a field bounary for some time, which protected one end of its carved surface. Now that it stands in the centre of a field it's in danger of disappearing for good.
The main decoration consists three large cup and ring motifs. The largest of these has five wide rings. This is nearly 50cm in diameter. Next to this is a smaller three-ring group and beyond that there is a four-ringed motif. Scattered around these are the faint traces of single-ringed cups and solitary cups.
At its largest the whole panel is 2m x 1.4m with the good carvings occupying its wider end.
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.
