Apollo 16 Hasselblad image from film magazine 122/QQ - Rendezvous, Lunar orbit.<br>This photo is used in Figure 4-41 of the <i>Apollo 16 Preliminary Science Report</i> (NASA SP-315), which has the following caption (edited for clarity by <i>italics</i>):<br>Mixed mare and highland terrain illuminated by a low Sun. In this oblique view westward across the mare-flooded Crater Letronne, Sun elevations range from approximately 6° at the <i>upper right</i> comer to 0° near the <i>lower left</i> corner. This low illumination shows the ropy features mapped as mare ridges to be superimposed on gentle swells generally 5 to 10 km wide; yet, except within craters, shadows are rare on the mare materials. By comparison, large areas of the highland materials are shadowed at elevations as great as 6° in the <i>right</i> half of the photograph. Approximately half the rim of the 110-km-diameter Crater Letronne is exposed. The crater is centered near latitude 10° S, longitude 42.5° W.
