This panel is not marked on the OS map. It lies in the small stretch of land between the road and the northernmost shore of Lough Fada.
The quality of the carvings surprised me. I have never seen an exposed panel with such clearly defined designs. The main motifs is a cup with three rings. The rings are over 1cm deep. To one side of this there is another cup and ring motif and a solitary few cups. There is a third cup and ring carved above the main motif.
It was here I bumped into local historian Desi McCillion and had a very interesting chat. He told me of some of the sites that follow this one on this trip. It was great to meet someone with such a passion for the history and prehistory of the area.
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.
