LO-IV-137H The Dorsa Ewing defined by the position and diameter given above (taken from the on-line IAU Planetary Gazetteer) extends from the upper left to the lower right of this Lunar Orbiter image. LTO 75C1 suggests it should include an additional ridge to the southeast (well outside the present view). The 4-km circular crater in the upper right (to the west of the unnamed hills) is Scheele. The slightly smaller crater to its southwest, near Dorsa Ewing is Letronne C. The pattern along the left margin is calibration data. To its right, the mountainous area is the east rim of Letronne.

Additional Information
At 11° south/ 36°15' west (near Dorsa Ewing and north of Rima Herigonius) is a cluster of bowl-shaped craterlets which is an interesting target for telescopic observers and photographers of minute features in the southern part of Oceanus Procellarum (see also: Apollo 16 Preliminary Science Report, P.29-91, P.29-80. Apollo 17 Preliminary Science Report, P. 31-4). - DannyCaes DannyCaes Nov 18, 2007 (calls "Ewing's mob").
Nomenclature
William Maurice; American geophysicist (1906-1974).
- Dorsum Ewing was among the many provisional dorsa names appearing on NASA’s LTO charts that were approved by the IAU “as now assigned and printed” (on those charts) in IAU Transactions XVIB. The labels on LTO 75C1 assign the name to two distinct ridges, the first corresponds to the present IAU position and diameter (as illustrated above), while the other starts to its southwest. The second ridge would extend into LTO provinces 75C4 and possibly 75C3, but since those LTO charts were never published, it is impossible to know how far the name was intended to extend. - JimMosher JimMosher
