Ah. Ok. I always use the google earth map.
sorry to go on but the Satellite button on the inline map shows brown edge circle in the heather the wrong side of the wall line.
If you can it should be moved north into the grassland on the other side of the wall that runs through the cairn. People trying to find the circle from the point it is placed at the moment have no chance. Moving it will at least put people in the correct area and give them a chance of locating it. if thats updated nightly too i apologise. : )
