Apollo 15 AS15-M2332 Mons Delisle is the club-shaped mountain. The crater in the upper right is Delisle, and a portion of Rima Diophantus is visible at bottom right.
Note the curious Bottle/ Guitar near the photograph's lower left corner (halfway between Mons Delisle and Fedorov). - DannyCaes Oct 17, 2015

Additional Information

  • From the shadows in AS15-M-2332, the spine of Mons Delisle is around 600-1000 m tall.
  • Measures on LRO QuickMap show highest part of ridge and of broader mass slightly more than 1 km high.



The Baby

  • Gerard Kuiper called this The Baby because, with a telescopic south up view and normal resolution, it looks like a big-headed child crawling southward (see image at right: Mons Delisle at a sun angle of about +0.6° from the east, as seen in Plate C22 of the Consolidated Lunar Atlas. Rotated so south is to the left and east up.)
  • Danny Caes calls the northern part of Mons Delisle "a mermaid's lower half, above the water" or "Fish's Tail".
  • In his informal 1953 tour of Mare Imbrium, Leland Copeland referred to Mons Delisle as the The Torch. Delisle Alpha (a peak to the northwest of Mons Delisle) was nicknamed The Triangle, while the elevation running from Mons Delisle to Diophantus was nicknamed The Wall. Research: Danny Caes.
  • An interesting photograph of both Mons Delisle and crater Delisle is included in Apollo Over The Moon: A View From Orbit, Chapter 6: Rimae (Part 2: Sinuous Rimae), Figure 199.
  • I still need a nickname for the odd cluster of craterlets west of Mons Delisle (an interesting test-object for common and large telescopes!). - DannyCaes Jan 2, 2017
