It looks like Miss Jocelyn Serot used only 12 inches of aperture for her picture. A nice accomplishment.

Chuck Wood's NAC picture shows the shadow indicating the west wall to dwindle in the northern half. I had thought the elevation difference was caused by an eastern uplift, but now I think a settling or slumping of the western plain is more likely.

This region of the Moon was the Lunar Photo of the Day on 03/07/13. Under the image for this day, Mr. Wood states that this is a mini-Straight Wall, similar to one south of Aristarchus, saying that this one is 34km long and 60-70m high. He states there is probably a relation of the two of them. You can read it here:

FYI, the above assessment was corrected by Woods the following day, March 8th; "... a graben, i.e., a tectonic rille. I have commented twice, yesterday calling it a fault (based on a QuickMap topo profile across a WAC image), and last month I reported that from LRO images that it was a narrow rille. From a plan view it is a rille/graben, the images commonly show the east side is higher as if it were a fault, and the topo cross-section (which I am not certain I completely believe) makes it a thin rille perched in the middle of a continuous rise. It is an unusual linear feature, definitely a rille, but also a shadow-casting elevation."

i agree; post emplacement regional uplifts of lava fields are uncommon to unknown where the opposite is common enough (subsidence).

Stop that!
Features on the moon are named for famous astronomers.
