Images
Johann Schröter carefully studied the changing appearance of the Montes d'Alembert peaks as a function of libration. The results of his analysis can be seen here and here, with additional drawings here, and possibly here (Figure 74?).

Description
Historic name for suspected mountain range near the moon's western limb, in reality the northern part of Orientale Basin seen in profile on the limb.
Description: Elger
(IAU Directions) D'Alembert Mountains. A range on the W. limb running S. from N. lat. 12 deg. ... A very lofty range on the W. limb, extending to S. lat. 11 deg.
Additional Information
- Most of these peaks would probably today be regarded as part of the Montes Cordillera ring of the Orientale basin.
- The peaks seen by Schröter can be readily identified if the date and time of his drawings of them are known. For example, the article by Baum and Whitaker (2007) mentions that his Plate XXX represents the Moon as seen on "1788 September 24 at 4.15 a.m." (presumably around 03:15 UT). Based on this information, a simulation of the expected appearance of the limb can be created using the Kaguya global DEM with LTVT (image on left). The peaks labeled by Schröter can then be identified in an aerial view based on the longitude and latitude of the points used to draw the corresponding features in the simulation (image on right).

Nomenclature
- Named for Jean le Rond d'Alembert (November 16, 1717 - October 29, 1783), a French mathematician, mechanician, physicist and philosopher. He was also co-editor with Denis Diderot of the Encyclopédie. D'Alembert's method for the wave equation is named after him. The crater D'Alembert is also named in his honor.
- The name Montes d'Alembert was assigned by Schröter to peaks he observed in the limb regions beyond Grimaldi and Schlüter.
- Mary Blagg found this name in use by all three of her authorities and included D'Alembert Mountains as Cat. No. 2020 in her Collated List. The name was adopted in this form in the original IAU nomenclature of Blagg and Müller (1935). Although Schröter had several separately named peaks, the IAU does not appear to have adopted Greek letters for them.
- The name was Latinized to Montes D'Alembert by the LPL, whose work was approved in IAU Transactions XIIB (1964).
- Montes D'Alembert was dropped by the IAU in Menzel, 1971, which found that "certain previously named features, especially those on or near Mare Orientale, proved to be non-existent". The name was reassigned to the unrelated crater now known as D'Alembert.
- Montes d'Alembert is still printed on some of the modern moonmaps, such as the Hallwag map.
