Although the sunrise in Cairn T didn't happen on the equinox (well obviously it did happen but the ist stopped anyone seeing it) here's some pictures from a few days later ... http://www.knowth.com/loughcrew-equinox-mar05.htm
"Symbols of the sun engraved on the backstone of Cairn T.. are precisely positioned to measure solar movement"
Watching the full moon rise behind the branches of a 100 foot fir tree last night makes perfect sense of the above statement........
Wow, they are some fantastic photos. Dang mist. On the other hand the misty morning fog was really atmospheric, you could wander over to the satellite tombs and it felt like there was no-one else around for miles. The fog kind of blew over the mountain top like waves, almost like a film set, I've never seen fog so thick. Kind of eerie yet beautiful, I wish I had a video camera as well as a camera to record the effect.
