These two stones stand about 15m apart. This would point to there once being others here that formed a row, rather than a stone pair. The tallest stone is large and square in cross section, with straight-looking side. I couldn't actually get right up to the stones, because the cows in the fields had young calves and I didn't want to disturb them.
The two stones are of roughly equal size, about 1.8m tall (using a cow as a remote measuring stick.) They stand on the top of a ridge, but heavy farming and high trees around the site block out all the views.
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.
