Visit Notes

Sunday, 29th October 2006

The path from the entance to the southern enclosure leads directly to these circles, not to the cairn as indicated on the site plan.

Each one is rather confusing. They are both made from low stones that would not have projected above the peat before excavation. The northern one is more of an oval aligned north south and seems to have a indentation at the southern end. The southern one is more round. Each one is about 10m max diameter and both have a confusion of other stones in their centres.

About Coordinates Displayed

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.
