This was a perfect way to finish a day! We eventually found this 3m x 1.4m rock after 20 minutes scouring the hillside 50m away (dodgy official co-ords!). Luckily we found it at the right time of day, with the winter sun setting low down and lighting up the markings perfectly. And what incredible markings they are!
On the upper surface there are two sets of concentric rings (7 & 8 rings), the centre cupmarks of which are joined by a gutter. To the east of these is a 7 turn spiral. Below them is a 6 six ring concentric motif also with a gutter (gutters are very rare in ireland), to the west of which is a faint 6 turn spiral. There are two very eroded spirals or concentric rings above this last spiral.
This has to be amongst the best rock art in Ireland!
GPS reading S 78793 48043 (accuracy = 6m) - look for a gorse bush around here and the stone shelters beneath that.

I thought the light was good the last time I was here, but today it was absolutely perfect! I can't say anything about this stone other than it is probably the best in Ireland!
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.
