Summary

[edit]
Description

(Processed) Apollo 14 Hasselblad image from film magazine 72/L - LM extraction, Lunar orbit. Shows Warner and Runge craters within Mare Smythii.
This is Figure 18-10 b of the Apollo 14 Preliminary Science Report (SP-272), which has the following caption:

Probable volcanic features near the eastern rim of Mare Smythii. (a) A sinuous depression (AS14-72-10008). (b) A multiringed crater pair (AS14-72-10026).

The text of the Report refers to the figure as follows:

East Rim of Mare Smythii
Mare Smythii, a near-circular basin, displays units with varying albedo. Near the eastern rim of the basin are somewhat hummocky units of high albedo. They are somewhat similar to the plains-forming units within large craters and appear to be made of older mare material. One example of the type of terrain is shown in figure 18-10 as a sinuous rille that crosses the middle of the photograph.
Several of the craters in this area appear to have been flooded and almost completely filled by mare-type materials. Although no distinct flows are decipherable, examples of flooded craters exist in the mare itself, as shown in figure 18-10. These multiringed craters appear to have been formed by eruptions and successive collapses much like calderas on Earth. They do not display hummocky ejecta on the rims, and no indications of an impact origin can be seen. Similar, but less distinct, craters on the east rim of Mare Smythii can be seen, and the setting also suggests that these craters are calderas formed by volcanic eruptions.
