This mound is high above the dam of the lower reservoir in Glanasmole Valley. It lurks in the corner of a field with hedgerows blocking all the views to the valley below. If opened up these would be spectacular.
It is 25m in diameter and reaches about 1.5m tall. It appears to have been raided at some point as much of the top has disappeared.
The nicest way to reach this mound is quite hard. I walked along the reservoirs in Glenasmole until I reached the lower dam. Cross the dam to the steep wooded hillside. It's uphill from here and it's very, very steep. Like all ground beneath trees it can be mulchy and slippery underfoot, so take great care. Good walking boots are essential. 30m or so above the end of the dam there is a pseudo-style - a break in the barbed wire on top of the fence. Cross the fence and keep going up. At the top there is a large break in the hedgerow. Go through this and then climb to the top of the field to another style. The mound is 20m into the field beyond the style.
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.
