This pretty little wedge tomb is a terrible one to find as it lies on the other side of a dry stone wall from the usual approach, under a tree.
It measures about 5 m in diameter and still has many kerb stones in place, but the cairn stone infill has mainly disappeared.
The single walled chamber is 'L' shaped (or possibly two connecting chambers at 90 degrees) and none of the roof stones remain.
When I visited someone had made a little camp out of the chamber by places branches across the orthostats and covering them with bracken.
Could I find this again? Could I heck! It took me ages. I felt a right fool to be honest. Anyway, we managed it eventually and finally put to rest the issue of the L-shaped chamber mystery.
The tomb has triple walling that is exceptionally wide apart - upto 80cm between each 'layer'. To the rear on of the side stones is missing from the inner wall and the wide gap to the middle wall looks like part of the chamber. Problem solved - it's just a wedge with big gaps between its walling.
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.
