This roughly linear formation of low ridges grazes the northwestern outer rim of the crater Secchi, the formation from which this range gained its name.

[1] This crater is named after Angelo Secchi, a 19th-century Italian astronomer.

In the vicinity of Montes Secchi is Mount Marilyn, a distinctly triangular mountain formation.

The selenographic coordinates of the range midpoint are 2.4° N, 43.6° E, and they lie within a diameter of 50 km.

This is smaller than the diameter of the crater Taruntius, located to the northeast of the mountains.
