A nearly identical image is used in Figure 4-33 of the Apollo 16 Preliminary Science Report (NASA SP-315), which has the following caption:

The stop at station 13 was to collect a series of samples from a permanently shadowed area. Shadow Rock, a 4-m-diameter boulder to the right in the photograph, was the location of the sampling. Permanently shadowed areas act as cold-traps, or areas where volatile and semivolatile components collect. Studies of samples from these permanently shadowed areas permit scientists to identify volatile components that are present in the lunar environment. The CDR works at the front of the LRV, adjusting the high-gain antenna. The high-gain antenna must be pointed at the Earth before ground control can receive TV. The hill above the LRV is the rim of North Ray Crater; to the right of Shadow Rock on the skyline is Smoky Mountain, approximately 1 km in the distance.
