Stone 16 is finely worked on the north eastern side, where it is on the side of the midwinter sunset alignment. The surface has been finely pecked to a smooth and straight surface, except for a nobble. This protrusion appears to have had its outer most part broken off but appears to have been deliberately left. It is just below head height.
I have no explanation for it and I try to avoid Pareidolia but it is reminiscent of a breast, or is that just me?
