English: This photo is an approximate replication of Figure 4-34 of the Apollo 16 Preliminary Science Report (NASA SP-315), which has the following caption:

The CDR prepares to sample material from the permanently shadowed area under the overhang at Shadow Rock. Close observation of the photographs indicates that Shadow Rock is a multirock breccia, a rock made up of other rock fragments that have been recombined to form a new rock. The holes or vesicles in the rock are much more elongated than previously observed; they appear to be more like vesicle pipes produced by venting gas. The rock also shows the presence of lineations, lines, or bands along the upper and right margin of the boulder. These bands may be caused by differences in lithology or may represent zones where the rock has been fractured and faulted.

This photo is also used in Figure 6-58 (a) of the Report, which has the following caption:
