We visited this formation after sunset at about 2130 this evening, 3 Aug.  The coordinates are:  420510,176387 which are a bit more accurate than the ones on the site. 

I apologize for the blurriness of the images, but it was pretty dark by the time we got there and I preferred to not use any flash.  I am sure better shots will become available in the coming days when it gets visited in the day time!  It is a spectacular setting overlooking Swindon, Barbury Castle and Liddington Castle as well. The lay is very fresh and spongy.  I am pretty sure that the laid triangular sections align with the cardinal points and the other four corners with the 45's.  The four corner boxes were pristine and all sealed by standing wheat except for the one that had tram lines running through them.  The energy was palpable and moved in fascinating serpentine fashion when we dowsed the flattenedtriangular sections.
