For the main entry on this boulder, see:
NS4576 : Boulder with possible cup-and-ring marks.
This photo shows faint markings that some have interpreted as traces of a cup surrounded by a double ring. The small dark indentation of the "cup" is placed exactly between the centre of the image and the middle of the upper edge of the photo. Around the near side of that mark, and located just above the centre of the photo, is a "U" shape that resembles the lower half of a ring, possibly continuing more faintly on the far side of the cup; outside of that, and only just below the centre of the image, is what looks like part of another ring.
When I took this photo, the sun was out; even so, the markings were very faint. Viewed in cloudy weather (such as when I visited the boulder a week later), the markings are effectively undetectable. These marks are not to be confused with a projecting oval area on the boulder (seen here at the upper left corner); that area can, at least in photographs, also look a little like a ring.
I am not adopting any position here on whether the faint marks described above really are the traces of a cup with two rings; however, I do believe them to be the markings that prompted the original report about the boulder in 1971 (see the link at the start of this item).
