This is a computer-generated 3-D view of a digital elevation model, with an ortho-image overlaid, that
was extracted from an Apollo 15 Metric camera oblique stereo pair (AS-15-M3-1445
& 1446, orbit 35). The outer western rim of Tsiolkovsky crater shows the
remains of a huge landslide. The stereo effect has been greatly exaggerated
here to enhance detail present in the feature.
