This oblique view of the moon is figure 3-7 of the <i>Apollo 15 Preliminary Science Report</i> (NASA SP-289, 1972), which has the following caption:
<dl><dd>The <a href="https://en.wikipedia.org/wiki/Mare_Imbrium" class="extiw" title="en:Mare Imbrium">Sea of Rains</a> illuminated by a low Sun angle. The mapping camera was used to photograph continuous strips from terminator to terminator on several revolutions. This oblique view northward across the Sea of Rains demonstrates the effectiveness of low-Sun illumination in accentuating features of low relief. <a href="https://en.wikipedia.org/wiki/Lambert_(crater)" class="extiw" title="en:Lambert (crater)">Lambert</a> Crater is just outside the lower right corner of the photograph, but ejecta from the crater extend into the field of view. <a href="https://en.wikipedia.org/wiki/Mons_La_Hire" class="extiw" title="en:Mons La Hire">Mt. Lahire</a> casts a very long shadow across the smooth mare deposits in the left central part of the photograph; <a href="https://en.wikipedia.org/wiki/Helicon_(crater)" class="extiw" title="en:Helicon (crater)">Helicon</a> and <a href="https://en.wikipedia.org/wiki/Le_Verrier_(crater)" class="extiw" title="en:Le Verrier (crater)">Le Verrier</a> are the large craters near the horizon. The Imbrian flows extend as a belt to the right and left from the prominent mare ridge. Lobate flow fronts along the north and south margins of the belt are clearly visible in the upper half of this near-terminator view. The protective cover remained within the camera field of view during revolution 35.</dd></dl>
