- Apollo 16 Surface Journal At the time of the Apollo 16 landing, surface shadows at this site would have pointed essentially due west. Hence this photo appears to have been taken looking south. The hill on the left is probably Stone Mountain, and the light area in the distance beyond Plum is presumably the bright ejecta blanket around South Ray crater. A small part of the lip of Flag crater is visible on the extreme right, as can be seen a larger panorama involving this frame.
- Detail of the Plum panorama above shows the location of the legendary rock called Big Muley (which is the largest one of all the rocks collected during the entire Apollo program!).

- Mike Constantine's assembled panorama shows Plum crater (central) and Flag crater (left, adjacent to Plum). Stone Mountain is at right. Compared to the image displayed above, the photos for this 360° view appear to have been taken from the opposite (south) rim of Plum crater , hence the left-right reversal in its position relative to Flag. The two astronauts in this panorama are both Charles Duke (photographed at different times).

- According to the Apollo 16 Lunar Surface Journal, Plum is about 40 m in diameter. - JimMosher
- The astronauts search for Plum crater is described in some detail on pp. 191ff of David M. Harland's Exploring the Moon: The Apollo Expeditions (Springer, 1999).
Astronaut-named feature, Apollo 16 site.
- IAU Transactions XVIB says that Plum is a "large crater with Flag on the rim," and the IAU Planetary Gazetteer gives Topophotomap 78D2/S1 as the primary map reference for this Landing Site Name. The name Plum is not listed on that map, nor on the Apollo 16 Site Traverses chart. Moreover, the IAU description conflicts with the Apollo 16 planning materials which identified Plum as a very small crater on the southeast rim of Flag, rather than the other way around. See for example the April 1972 Lunar Surface Procedures traverse map and the labeled aerial photo from the Apollo 16 Surface Journal website. - JimMosher
