Summary

Description
English: Subframe of AS16-P-5400, with approximate north to the left. This is an approximate reconstruction of Figure 29-64 of the Apollo 16 Preliminary Science Report (SP-315, 1972), which has the following caption:
Photograph of crater 430 m across with blocky ejecta and central mound; largest block is approximately 11 m across.

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

The Apollo 16 crew collected important photographic data on the variation in morphology of primary impact craters with size of the crater. Typically, young lunar craters in the 400 to 600 m sizes, such as South Ray Crater and the crater shown in figure 29-64, have central mounds or concentric structures within the crater, depending on the target material (ref. 29-66). For these craters, abundant blocks between 1 and 20 m in size occur in the ejecta. Large blocks also are found in the ejecta of larger craters (2 to 10 km across), such as Mosting C, Censorinus, and the 3.1-km-diameter crater shown in figure 29-65. Such blocks may be as large as 35 to 60 m, depending on the crater diameter. In contrast to the smaller craters, dunelike structures with long axes concentric to the crater are found around the flanks. Commonly, such dunelike structures completely surround the crater, but they may be confined to sectors of the ejecta as in figure 29-65. These craters are typically bowl shaped and devoid of concentric structures and central mounds within the crater.
The crater at center is located at 10.444° S, 9.904° W.
