English: Lunar surface imaged by Surveyor 1. Figure 7-41 of NASA SP-184, caption reads:

FIGURE 7-41.-The panoramas of the mare areas were quite similar. Although more rocks, hills, and steeper slopes occur north of Tycho, the general morphology is similar to that of the maria. (a) Surveyor I (b) Surveyor III (c) Surveyor V (d) Surveyor VI (e) Surveyor VII.
A comment in NASA SP-168 on the same photograph reads:

"A surface born in violence!" exclaimed RALPH B. BALDWIN, a noted astronomer, referring to the lunar scene above. "Prominently displayed on this Surveyor view of a mare is a small crater, perhaps 3 meters across, dug by the impact of a small meteorite. Scattered essentially at random over the surface are numerous rocks ejected from other, larger craters.
"In the distance," Baldwin pointed out, "is a strange wall of rocks. Study shows that these rocks lie, in part, on the near wall of a crater some hundreds of meters in diameter and, in part, in a sort of raylike extension of the crater wall. They were thrown out when the crater was formed. It is not known whether they represent true subsurface, stony materials, or are pulverized materials consolidated by the shock waves from the violent impact."
