Apollo 15 AS15-M-2332 Delisle is the main crater near the center, with Mons Delisle to its lower left. Below Delisle, the tiny crater at the center of the area dusted with light colored ejecta is 2-km diameter Samir, with even tinier Louise by its side (on the east). Rima Diophantus winds across the frame from a series of small pits below Mons Delisle to the middle right margin. The shadowed 6-km circular crater below it is Diophantus B. In the upper right, a separate rille, Rima Delisle, exits an odd elongated trench.

Description
Elger
(IAU directions) DELISLE.--A larger and more irregularly-shaped object than Diophantus, 16 miles in diameter, with loftier and more massive walls, and an extensive but ill-defined central hill. There is an evident break in the northern border. A triangular mountain on the S.W. and a winding ridge running up to the N. wall are prominent features at sunrise, as are also the brilliant summits of a group of hills some distance to the W.N.W.
...
Delisle Beta. A curious club-shaped mountain on the S.W. of Delisle, nearly 4,000 feet in height.
...
S. of Delisle there is a tolerably bright spot on the site of some hills.

Additional Information
- IAU page: Delisle
- Depth data from Kurt Fisher database
- Pike, 1976: 2.42 km
- Arthur, 1974: 2.56 km
- Westfall, 2000: 2.42 km
- Viscardy, 1985: 2.55 km
- Cherrington, 1969: 2.4 km
- Indefinite central peak 0.64 km high, according to reading of LTO 39B2 chart by Kurt Fisher.
- Delisle and the tiny bright crater to its south (Louise or Samir??) are thermal anomaly craters, implying youthful ages - Moore et al, 1980
- TSI = 25, CPI = 20, FI = 20; MI =65 Smith and Sanchez, 1973
Nomenclature
- Named for Joseph-Nicolas Delisle (4 April 1688 - 1768), a French astronomer. He created his own observatory in the palace of Cluny, later made famous by Charles Messier.
- According to Whitaker (p. 218), the name for this crater was introduced by Schröter in the form de l'Isle. Most later observers used the modern spelling, which was adopted into the IAU's Named Lunar Formations (1935).

- In Mysterious Universe, a handbook of astronomical anomalies (1979) :
- Page 73: The Blunted Cusp Effect and Terminator Irregularities (at planet Mercury) (Dale P. Cruikshank, Strolling Astronomer, 1963). Note, in this article, Delisle is mentioned as de l'Isle. There's quite a lot of names in this article: Schroeter, Antoniadi, Burton, Noble, Franks, Trouvelot, Denning, Fournier (G. and V.), Schiaparelli, Lambert (because of his cosine law of diffuse reflection), de l'Isle, Wegner, Dollfus, Lyot, Camichel, Johnson, Smith, and Haas. The odd appearance of planet Mercury (as seen through a telescope) must have been a most important subject in those days...
