Apollo 16 Hasselblad image from film magazine 119/RR - Lunar orbit.<br>This photo is used in Figure 4-43 of the <i>Apollo 16 Preliminary Science Report</i> (NASA SP-315), which has the following caption:<br>Southeastern Alphonsus Crater. The dark-halo crater and the rilles near the bottom of the frame are in the southeastern quarter of the floor of Alphonsus. Grooves or irregular valleys, like the conspicuous feature extending upward from the base of the wall near the dark-train crater, are the dominant crater wall structures in the eastern half of Alphonsus. These features are radial to the lmbrium Basin and are part of that family of widespread structures called Imbrium sculpture. Terraces, which are more typical of the walls of large craters, predominate on the northern wall of Arzachel Crater at the extreme top of the frame.
