I love bullaun stones like this: rough, craggy and oozing prehistoricness. I parked at the church just up the road and asked someone who was just leaving if they knew where the stone was - "It's in the bog in that field, I think." In a bog? Great!
Luckily it just turned out to be a very soggy field and I had my wellies with me, so I was ok.
The stone is difficult to spot, as it only stands 15cm proud of the ground. It is over 1m long and just 40cm wide with two 25-30cm bullauns near to one end. The grass around it appears to be trying to consume it, so I cleared it off a bit to give it a chance. The roughness and glorious cragginess of this stone is so primeval, almost, that it has entered into my list of favourite bullaun stones.
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.
