As I was walking back to the car I took a small detour to see a modern monument in a field just of my direct path. This monument is a modern totem pole type post with a peace inscription and some ogham. This diversion was a fortuitous one, because my altered route took me past this amazing feature.
I couldn't believe my eyes when the sun cracked through the clouds and mist, and a row of at least eight small bumps cast shadows across the grass. I have never heard of this group of mini-barrows before, so I may have discovered something new. Please get in touch if you know of any record of them.
Each barrow/bump is just 3m or so across. All except one at the northwest end line in a dead straight line with a southeast-northwest alignment. At the southern end there is a large patch of gorse that could be covering a larger monument connected with the row.

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.
