When I first saw this lake, 500m above sea level, I was dumb-struck. All that kept going through my mind were the first few lines of Dylan Thomas' 'Under Milkwood'.
It really isn't surprising that this place became sacred. The black peaty water seems to have a life of its own. The little chopping waves appear to go where they please, not bothering to take any notice of the wind. The sound of them lapping against the peaty bank here and a rock there tick-tocks with an out of time rhythm, if that's possible, and holds you transfixed.
The lake is known as Calliagh Berras Lough. Who better to give this lake to than the Hag?
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.
