R1: Promontorium Kelvin was well lit and appeared to be joined to Rupes Kelvin by a narrow isthmus. Rupes Kelvin was less well-defined; appeared as a broken up range of mountains.
R2: Rimae Hippalus runs north to the degraded crater Hippalus. It looked like a thin valley with a rim.
R3: There was an extensive system of wrinkle ridges in eastern Mare Humorum. Several formed a semi-circle of sorts that ran from Gassendi in the north to Loewy to Pulseux to Vitello in the south.
C1: Rimae Hippalus runs north to the large crater Agatharchides. The crater's northern rim appears broken/fragmented.
