I'm not sure about this being a boulder burial, but it could well be. It is certainly a glacial eratic that seems to have been manipulated. It is located on a steep slope with one edge resting on some exposed bedrock. The other edge is raised up on a small sandstone pillar making the upper surface level. There may be a small chamber-like construction tucked away underneath it, but it's hard to tell.

What is really interesting is that the upper surface seems to have some worn rock art motifs on it. Towards one edge there is a pair of cupmarks and on the far side there is a warn cup and ring motif. A rock that stands next to it is peppered with small weathered depressions that may or may not be natural.

I'm still not 100% sure about the classification of this as a boulder burial, but I did encounter another site in the forest here that could be another example of a glacial eratic used as a boulder burial.

Miscellanea

The cup and ring motifs were uncovered and first seen by Gabriel Burns and Jim Nolan. Apparently there some similar motifs on a boulder nearby.

About Coordinates Displayed

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.
