|Scartnadrinnymountain - Cairn|
Of the three recorded cairns here only two are visible ... and I'm not sure about the other one. This one is detectable only because the knee-high heather and bracken rises 1m above that around it. When you reach the cairn you can see the cairn material poking through the soil below.
The site is in a shallow saddle between a rocky outcrop to the south and a towering cliff to the north. To the west the Knockmealdown Mountains form the horizon, while to the east Seefin Mountain terminates the views. The complexes in Coumeraglinmountain townland are all visible from here.
It is hard to see the extent of the cairn, but it is around 8m in diameter. Forestry activity in the immediate vicinity has disturbed at least one of the cairns here.
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.
