R1:  Dorsa Aldrovandi off the eastern shore of Mare Serenitatis, running between Mons Argaeus and Le Monnier.
R2: Mons Argaeus helps form the south end of the dorsa and forms the western mountain range of the area where Apollo 17 landed.
R3: The west rim of Le Monnier on Mare Serenitatis has eroded; looks more like a bay of the mare. Luna 21 landed in the southern area of the crater (or should I say 'crashed'?).

C1: Mons Vitruvius and the Apollo 17 landing site were located. Catena Littrow and Rimae Littrow were not identified.
C2: Lighting was not sufficient during this observation to identify the broken northern areas of the Dorsa.
