Once again an electric fence does more than keep the sheep in the field, it keeps me out too.
This stone seems to be about 1.7m tall and slab like, oriented east-west. It is very nicely situated on the brow of a ridge.
From Tullow take the N81 for about 5.5km until you reach a cross roads and turn left. Continue for a little over 1km until you reach a fork in the road with a large triangle of land in the center of the junction. To the left you will see a farm track, drive up this and stop at the farm yard. Ask at the lower house to visit the stone. Continue on foot up the track for until you pass the last farm building and the stone is on the ridge to the right.
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.
