"The OS have a cairn not a currick marked at the top of Kip law .From the site of the stone (which is not 100 % accurate as I ‘m not sure which one it is as seen on GE but this will have little impact on the result as both extremes of the “wall “ occupy less than degree at the distance to Kip law plus I believe it is fairly central ) to the summit is 105 degrees which provides a declination of minus 3.9 ."

GoogleEarth does have the stone marked in the wrong place. The cairn on Kip Law is quite high - shows in profile for quite a long distance. Working things out roughly generates errors. - 3.9 is close to 0, which is the declination of the sunrise at the equinoxes, all things being equal. Roughly it will be possible to see the sun rise from behind the Kip Law Cairn from the proximity of the main stone row at Thornhope. It's certainly strong enough to test on site.
