I have taken some photos from Deacon Hill and been in the formation. It seems to be two interlocking circles forming a figure of eight with another circle inside the first of the larger circles. there is an elliptical 'teardrop' almost like a pendant at the base of the first circle and the symbol is mirror image spirals that are joined above the teardrop and inside the enclosed circle. I don't have a digital camera so can't e mail you any pictures could scan in a drawing I made if you like. It was hard to follow the pattern inside without really knowing what I was looking at-there is a nice lay ,no breakages, the lay swirls around the formation and changes direction with some laid on top of others  going in a different direction. No sign of footprints-any welly prints are mine! No sign of entry. It's in the next field to last years formation.
