Why would they be visible at all on the dark side of this mountain? Nothing else in that shadow of the mountain is catching any sunlight.
That makes me think it might be some sort of image glitch -- whether it's a real feature/crater that got reapeated in the process of stitching together the image, or is an repeating image artifact that looks coincidentally like a crater.
They also do not appear in the LRO images of the Moon:

The pic with the multiple 'footprints' is interesting.
These images purporting to be foot prints are hexagonal in shape and apparently such shapes are found on just about all of the planets that have been filmed sufficiently close up to make recognition of shape obvious.
The Lunar Orbiters had an ingenious imaging system, which consisted of a dual-lens camera, a film processing unit, a readout scanner, and a film handling apparatus. Both lenses, a 610 mm (24 in) narrow angle high resolution (HR) lens and an 80 mm (3.1 in) wide angle medium resolution (MR) lens, placed their frame exposures on a single roll of 70 mm film. The axes of the two cameras were coincident so the area imaged in the HR frames were centered within the MR frame areas. The film was moved during exposure to compensate for the spacecraft velocity, which was estimated by an electro-optical sensor. The film was then processed, scanned, and the images transmitted back to Earth.
The film was developed on-orbit in a semi-dry process, and then scanned by a photomultiplier for transmission to Earth
