These stones are tucked away behind the old sawmill and annoyingly in a big thicket of gorse. As we approached I didn't think we'd find anything, but we soon spotted the main stone. This was doing its best to avoid detection though, being full of gorse needles. The picture of the stone I had shows it standing up on edge so the the bullaun is in a vertical surface. The stone now lies flat, which is a shame as there is a second basin in the other side. The two bullauns have actually broken though into each other.
Next to the river and underneath all the gorse there is a small fragment of another bullaun stone. Several of the rocks around this have drilll holes in them, indicating that there was some blasting done here at some point. Obviously one of the rocks blown up had a bullaun in it. All that remains now is a thin slither with about a quarter of a bullaun in it. From the curvature of the fragment this would have been a big bullaun.
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.
