Visit Notes

Sunday, 19th October 2008

On this visit the rain was pouring down and the mist was thick. I only found this stone because I had the GPS coordinates for it. The whole area here is strewn with boulders and old field walls, which means that you have to check every stone even when you have accurate GPS readings. The ground is very boggy, too, and the high reeds mean that you'll get very, very wet walking around here if it's been raining recently.

The panel is about 1.5m x 1.5m and next to a short stretch of wall that seems to serve no purpose. A crack along the rock separates a cluster of cup-and-ring motifs from a larger cup-and-ring design.

I wish I could tell you more and that my pictures were better, but the weather really was foul. I will be back to this townland to seek out the many other stones in the area, and I'll definitely come back to this one.

About Coordinates Displayed

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.
