Interesting following a story through, but Past Horizons have written the article below on this Lidar survey paid for by the wind farm (21 turbines) on 7 neolithic cairns in Caithness. Carl and Greywether are the only people to have visited it though it is up at the furthermost part of Scotland a long way to go....
