LO-IV-090H The fluted hills in this area just west of [/Menelaus Menelaus] (whose sunlit west rim interrupts the right margin) are an example of the Imbrium Sculpture. They have been raked in a direction radial to the center of [/Mare%20Imbrium Mare Imbrium]. The shadowed crater to the right of center is [/Daubr%C3%A9e Daubrée]. Two of [/Menelaus Menelaus]'s satellites are also visible: 7-km [/Menelaus Menelaus] A in the upper right and 4-km [/Menelaus Menelaus] C near the bottom. The dark region in the upper right is a small part of the floor of [/Mare%20Serenitatis Mare Serenitatis], while the similarly-dark regions to the left and bottom are regarded as parts of [/Lacus%20Gaudii Lacus Gaudii] and [/Lacus%20Hiemalis Lacus Hiemalis].

Description
Additional Information
- Many valley-like (or "groove"-like) depressions in the neighbourhood of the [/Ptolemaeus Ptolemaeus]-[/Alphonsus Alphonsus]-[/Arzachel Arzachel]-[/Albategnius Albategnius] group were formed during the impact which created the [/Mare%20Imbrium Imbrium basin]. One of those valleys runs at the western rim of nearby crater [/Gyld%C3%A9n Gyldén]. Another one runs at the south-southeastern part of [/Parrot Parrot]. A survey of all these radial "grooves" and their observability through all sorts of telescopes is needed!
- Other examples of the Imbrium radial sculpture are the hills [/Fra%20Mauro Fra Mauro] Eta and Zeta (northeast of [/Fra%20Mauro Fra Mauro]). [/Fra%20Mauro Fra Mauro] Eta is literally pointing like an arrow toward the impact location of the [/Mare%20Imbrium Imbrium basin].
- The environs of [/Ukert Ukert] are "heavily" occupied by radial surface formations, all "pointing" toward the location of the [/Mare%20Imbrium Imbrium basin]'s centre.

- Gilbert's 1893 sketch of the Imbrium Sculpture (based on 18 nights of observations) can be found on page 277 of his monograph.
- Hartmann (1963) concluded that gouging by flying fragments could not explain the "sculptures" and suggested they were caused instead by radial fractures.
- Head (1976) compares the two then prevailing theories of the origin of the sculpture (erosion by and deposition of ejecta versus faulting along fractures created by the impact) and comes down on the side of the "sedimentary" hypothesis (erosion by and deposition of ejecta).
Nomenclature
- The term Imbrium Sculpture was introduced by the geologist [/Gilbert G. K. Gilbert] (1893), to whom it, and other similar sculptures, presented clear evidence of the impact origin of the lunar basins.
- The valley running near and at the western rim of [/Gyld%C3%A9n Gyldén], which is part of the Imbrium radial sculpture, is unofficially called Vallis Gyldén by D.Caes.
- The valley (or rather "groove") running at the south-southeastern part of [/Parrot Parrot] (also part of the Imbrium radial sculpture) is unofficially called Vallis Parrot by D.Caes.
- Note: It would be a most interesting project to give official (or unofficial) names to all the radial valley-like (or "groove"-like) depressions and chains of craters related to the Imbrium radial sculpture. The start of such a project is online in the lower half of the page [/Lunar%20Valleys Lunar Valleys].
