Orbital photo of lunar surface.  Crater in lower left corner is Seleucus E.<br>This photo was used in Figure 25-93 of the <i>Apollo 15 Preliminary Science Report</i> (SP-289, 1971), which has the following caption:<br>Near-terminator photograph of intersecting mare ridges a few kilometers east of Seleucus Crater in western Oceanus Procellarum. In addition, the photograph shows a broad ridge of low slope that lies beneath the mare ridge but is several times wider than the mare ridge. The structures indicate that the material that produces the narrow ridge may bow up a considerably wider area underneath before coming through to the surface.
