Kies is a flooded crater with a nearby volcanic dome designated π (Pi). Mercator and Campanus are two nearly equal-sized craters located at the edge of Mare Nubium.

R1: Directly south of Bullialdus is Kies. It's walls are barely seen; the SW has a small area that is quite high. It's shaped like a small magnifying glass, short handle that may be higher in elevation than the crater walls. |

C1: The volcanic dome just west of Kies designed π was observed; it appeared as a slightly raised area.
C2: Mercator does not have a peak whereas Campanus does. Campanus has a peak, its floor is darker and its sides steeper than those of Mercator. The unnamed rille appears as a thin dark line between the two craters; the south section curves into an area between the craters then heads north towards the small mountains on the mare floor.
