This range lies across the Moon’s southwestern limb, meaning it is observed from the side when viewed from Earth.

The northern portion lies just south of the lunar equator, while the southern extent reaches about 38° S. The inner side of the range consists of an uneven, ring-shaped plain surrounding Montes Rook, while the outer side features a wide blanket of ejecta created during the formation of Mare Orientale.

These ejecta have created ridges and valleys radiating from the mare and have significantly altered nearby pre-existing craters.

[3] Along the inner side of the range, to the northeast, lies a small lunar mare feature called Lacus Autumni, or Autumn Lake.

Hartwig has been heavily modified by ejecta from Mare Orientale, whereas Schlüter is a younger crater, formed after this impact.
