What an eerie place. The husks of these old dwellings, surrounded by the granite boulders in their rock slides, is quite chiiling. They are slightly too delapidated to give the impression of a ghost town, but you can imagine how hard life here must have been.
Evidence of the mining lies everywhere, from rusty machinery to simple wooden culverts now clogged and failing to redirect water as they once did.
If you go to Glendalough then this place is well worth the extra 2km walk.
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.
