- The arc of Dorsum Oppel is noticeable near the centre of Apollo 17's vertical mapping/metric Fairchild camera photograph AS17-M-0290 (north toward the frame's right margin).
- Dorsum Oppel's A-to-B section was also captured on Apollo 17's orbital panoramic ITEK-camera frames AS17-P-2253 and 2258.
- Additional research Apollo 17 photography: Danny Caes
Albert; German palaeontologist (1831-1865).
- Dorsum Oppel 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. It is labeled on LTO-62A1 and LTO-44D4 . Unfortunately LTO-44D4 terminates at the point “B”, and there is neither an LTO nor an LM chart of the region north of that. Since the ridge continues unbroken to the north of “B” one can only assume the IAU meant the name Dorsum Oppel to apply to its full length, which reaches to roughly point “C” (near Cleomedes F). However, since the IAU approved the name as “assigned” on the LTO, and since there is no LTO of this region, the northern extent of Dorsum Oppel is ambiguous.
- The position and diameter currently listed for Dorsum Oppel in the on-line IAU Planetary Gazetteer (and repeated on the title line of this page) seem to be based on the assumption that Dorsum Oppel was meant to extend from “A” to “C”.
