Rupes Altai is the outer ring of the Nectaris basin (Mare Nectaris).
There are many Rupes (mountain rock lines) on the lunar surface. These are remnants of the rims of old craters. Rupes Altai is a mountain range 427 km long.
Rupes Altai ends at the western edge of the crater Piccolomini. It is an irregular region with no terminus clearly defined, and where the craters Theophilus, Cyrillus and Catharina are located. Rupes Altai forms the southwest edge of Nectaris impact basin.
Rupes Altai is difficult to locate during the full Moon when the Sun is almost over these formations. It is best observed when the shade is nearby and sunlight reaches a low angle.
