A close look at the photographs on this page (courtesy of Steve Alexander/Temporary Temples) reveals the formation is on top of a discoloured area of crop. This ground marking has inspired a little online debate, a few people suggesting it’s sat on the ‘ghost’ of an old crop circle. However, it’s actually the remains of a tumulus, confirmed by an Ordnance Survey map of the area from 1958.
