This beautifully decorated stone is amongst the debris of an ancient wall that cuts across the stone circle. On the upper surface there are three finely carved cup and ring marks. The delicateness and style make these look more like the passage tomb art of this area rather than the open air panel style rock art.
The boulder is about 1m x 50cm and is almost lost amongst the other stones piles around it. To find it quickly look at the stones on the circle-centre side of the rubble.
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.
