LO-IV-150H The prominent 11-12 km craters on the right are Marius B (top) and Marius C (bottom). Rima Marius winds to their west and north, reaching 4 km Marius P, where it turns a continues a bit farther to the west southwest. The IAU position and diameter quoted above is not large enough to include the part beyond Marius P.

Rima Marius was captured on several southward looking oblique Fairchild camera frames made during the mission of Apollo 15. One of these frames is AS15-M-2610 (Hi-Res scan) in which the snaky Rima Marius is seen about halfway between Herodotus (leftward of the frame's centre) and Marius (in the distance, at the curved horizon).

Additional Information

The very erratic looking meandering sinuous rille north of Marius P

  • The bowl-shaped crater Marius P is the local "roadsign" to detect the most northern section of Rima Marius. Slightly north of it runs another rille. This sinuous rille is a very difficult one to observe through telescopes, but... very easy to spot on the "Big Shadows" version of the WAC on the LROC-Quickmap! See: http://bit.ly/2iOsGyY . The typical "look" of this kind of sinuous rilles (of both Rima Marius and the unnamed one north of it) is very much like the thin meandering "fissures" in a human skull. I wonder if there are much more examples of this sort of erratic meandering appearances in nature (on earth and on other bodies in the solar system). - DannyCaes Oct 29, 2017


Named for nearby crater (Marius).
