LO-IV-126H Rima Gay-Lussac is the rather faint diagonal groove in the center of the image. On the right, the circular 2-km wide crater, surrounded by dark material is Gay-Lussac N. Near the left margin, a bit above center, in another dark area, can be seen 5-km Gay-Lussac H (with the small central peak).
Named from nearby crater. (Gay-Lussac)
