But I did notice something unusual. One of the statistics that Google Earth provides is the coordinates of an object.
I found that the latitude of the monolith at Rudston matched the latitude of the northernmost stone of The Devil's Arrows.
Not just to the degree, and not even to the same minute, but to the same second i.e. 54degrees, 5 minutes and 37 seconds.
But I do not know how accurate Google Earth is with its coordinates.
So if anybody has a GPS and cares to measure the latitude of each stone, I would be most grateful if you could post the results here. I would do it myself but I live 200 miles away.
