Description
Bounding the tiny break in the western rim of the [/Mare%20Crisium Crisium Basin] are two headlands that almost meet. To the north is the area east of the crater [/Proclus Proclus] P, and to the south is the eastern wall of [/Glaisher Glaisher] X. Each of these headlands was named in the late 1800s by the English selenographer William Birt. He called the northern one Promontorium Olivium and the southern [/Promontorium%20Lavinium Promontorium Lavinium]. Both of these names were included in [/Named%20Lunar%20Formations Named Lunar Formations] and in the [/System%20of%20Lunar%20Craters System of Lunar Craters], but do not appear in the current list of IAU names. Prom. Olivium is broad and flatly rounded in cross-section, it appears to be the continuation of the [/Mare%20Crisium Crisium Basin] rim. [/Promontorium%20Lavinium Prom. Lavinium] is narrower with a more V-shaped profile - it cast the more dramatic shadow under low illumination. These are conspicuous landmarks and these names should be re-instated.
Additional Information
- The southwestern slopes of the peak in Promontorium Olivium formerly known as [/Mare%20Crisium Mare Crisium] Epsilon has an odd terraced structure -- like fish scales -- visible in the Lunar Orbiter photo when viewed at higher magnification.
- Promontorium Olivium is the site of the somewhat infamous [/O%27Neill%27s%20Bridge O'Neill's Bridge].
Nomenclature
- The name Promontorium Olivium, as well as the names [/Mare%20Crisium Mare Crisium] Delta and [/Mare%20Crisium Mare Crisium] Epsilon, appeared both in the [/Collated%20List Collated List] (1913) and in [/Named%20Lunar%20Formations Named Lunar Formations] (1935, where Prom. Olivium was Catalog #99). The coordinates given for Prom. Olivium are extremely close to those for [/Promontorium%20Lavinium Promontorium Lavinium], suggesting the name referred just to the thin cratered southern tip of the northern headland. The position given for[/Mare%20Crisium Mare Crisium] Epsilon corresponded more closely to the main peak, as illustrated by the labels on the [/Lunar%20Orbiter Lunar Orbiter] image reproduced above. On maps A3 and A4 of the [/System%20of%20Lunar%20Craters System of Lunar Craters], the names [/Mare%20Crisium Mare Crisium] Delta and [/Mare%20Crisium Mare Crisium] Epsilon were dropped and the outline of Promontorium Olivium was extended up to include that area. However neither Prom. Olivium nor [/Promontorium%20Lavinium Promontorium Lavinium] were labeled on the contemporaneous [/LAC LAC] maps (although [/Mare%20Crisium Mare Crisium] Delta was). Promontorium Olivium does not appear in later lists of [/IAU%20nomenclature IAU-approved nomenclature]; yet it also does not appear on any published list of deletions, and the name does not appear to have ever been formally dropped.
