To the west of the range is the level and nearly featureless mare, while on the eastern face is a more rugged continental area with a higher albedo.

[4] The Alpes, being part of the middle ring, thus have a shorter radius to the center of Imbrium than the other ranges of the basin.

[5] About one-third the length of the range from the southeast is Mons Blanc, a peak rising to a height of 3.6 km.

To the southwest of Promontorium Agassiz is the isolated Mons Piton, a peak rising to a height of 2.3 km.

Blanc, Piton, and the Montes Teneriffe make up part of the inner ring of the Imbrium Basin.
