AS 15-86-11607 - My Shadow, the "Glass Sphere" and a "Pin-Pin"

Caption NASA:"142:56:47 MT - At the start of EVA-2, Dave (Scott) took 3 cross-Suns from the north of the small Glass Sphere that he had noticed on the ground under the Rover stowage position prior to the first EVA at 108:30:36 MT.
This is the fourth of those pictures.
The piece of hardware on the ground is probably a so-called "pip-pin" that was pulled off the Rover during the deployment.
The "aggie" is just beyond the relatively large rock that is immediately above and to the left of the pip-pin".
