Mount Hadley

(discontinued IAU name; current IAU name: Mons Hadley)
Lat: 26.5°N, Long: 4.7°E, Diam: 25 km, Height: 4.8 km, Rükl: 22
Lunar Orbiter IV-102H remapped by LTVT -- a portion of Hadley Rille (official name: Rima Hadley) and Mons Hadley Delta are visible at the lower left of this picture. The meaning of the IAU's Mons Hadley is slightly confused but it presumably includes one or both of the large shadow-casting peaks in the center of this view (see Nomenclature, below).

There's a total of 21 LEVA-Hasselblads which show "portraits" of Mount Hadley. In the list below, I arranged all of these Hasselblads into "the lunar day's first half". - DannyCaes DannyCaes Jan 20, 2008

1: AS15-85-11364 (made during the Stand-up EVA of CDR David Scott).
2: AS15-87-11740 (made during the Stand-up EVA of CDR David Scott).
3: AS15-85-11404 (+ tracks of the Lunar Roving Vehicle, LRV).
4: AS15-85-11428
5: AS15-85-11454
6: AS15-86-11603 (+ Lunar Roving Vehicle, astronaut). This is one of the most well-known and most reproduced photographs of an astronaut + rover.
7: AS15-90-12186
8: AS15-85-11488 (+ tracks of the Lunar Roving Vehicle).
9: AS15-85-11511
10: AS15-90-12208
11: AS15-90-12244 (+ crater Dune in the foreground).
12: AS15-92-12426 (+ astronaut's Portable Life Support System/ PLSS "backpack", and leg).
13: AS15-82-11052
14: AS15-82-11075 (+ field of small rocks).
15: AS15-82-11116 (base of Mons Hadley hidden, below "horizon").
16: AS15-82-11173 (base of Mons Hadley hidden, below "horizon").
17: AS15-87-11793 (+ astronaut's bootprints and tracks of the Lunar Roving Vehicle).
18: AS15-87-11811 (+ tracks of the Lunar Roving Vehicle).
19: AS15-87-11835 (+ tracks of the Lunar Roving Vehicle).
20: AS15-87-11849 (+ astronaut's bootprints).
21: AS15-88-11904 (high sun, the whole of Mons Hadley's southwestern flank is in full sunlight). Note the plaque of the 14 perished cosmonauts and astronauts at left (the small "white square"). AS15-88-11894 is a close-up of that plaque.

AS15-84-11310 is one in a series of 500 mm close-ups of Mount Hadley's top and "diagonal banding" effect on its flank. An interesting reproduction of these photographs (a composite panorama) was printed on pages 230, 231, and 232 of the article To the Mountains of the Moon by Kenneth F. Weaver (National Geographic, february 1972). - DannyCaes DannyCaes Jan 29, 2008

Mons Hadley is the northernmost of the prominent named peaks in the lunar Apennines. Those peaks generally increase in height as one goes south.

Description: Elger

(IAU Directions) MOUNT HADLEY.--The northern extremity of the Apennines, in N. lat. 27 deg. E. long. 5 deg., rising more than 15,000 feet above the Mare.
The great headland Mount Hadley rises more than 15,000 feet, while a neighbouring promontory on the south-west of it is fully 14,000 feet, and another, close by, is still higher above the Mare.

Additional Information

  • Depth data from Kurt Fisher database
    • Viscardy, 1985: 4.8 km
    • Cherrington, 1969: 2.89 km
  • There are several distinct peaks in the area. Stereo mapping of Apollo images (used to produce NASA's LTO and LM charts) resulted in the conclusion that the summit of the eastern peak (9450 m) was very slightly taller than the western one (9407 m -- both heights being referred to an arbitrary 1730 km reference level).
  • The breaks near the tip of the large pyramid-shaped shadow from the western peak indicate undulating terrain at the foot of the mountain. The elevation of the plain near the tip of the shadow is about 5300 m (on the same scale), giving an elevation for the peak of about 4100 m (relative to that level). The eastern summit casts relatively little shadow in this view, but that is because it is interrupted by the high ground of the western peak.
  • The peak was measured at (4080 +/- 80) m (Boint, 2001). - fatastronomer fatastronomer
  • The Apollo 15 landing site is to the east of Rima Hadley, just north of Mons Hadley Delta, in the much larger plain known as Palus Putredinis. - JimMosher JimMosher


  • Named for John Hadley (1682-1744); British instrument maker.
  • The name Mount Hadley, in the original IAU nomenclature of Blagg and Müller, was Latinized to Mons Hadley in 1964.
  • The name Hadley was briefly used by the IAU to refer to the crater known as Hadley C.
  • Although there is no record of any intentional changes having been made over the years, the exact meaning of the IAU's present Mons Hadley is not entirely clear. The System of Lunar Craters called the entire complex of peaks, including the two major ones and a bit of the area to the south, Hadley (without the "Mount"). By contrast NASA’s LAC-41 identifies Mt. Hadley with just the eastern ridge. But NASA’s later LTO-41B4 and LM-41 shifted the identification to the western peak. Most amateur astronomers probably share this identification of Mons Hadley as the more massive, shadow–casting western peak or possibly the combination of the two, since that is how it seems to be labeled in Rükl; but the present on-line IAU Planetary Gazetteer diameter and position correspond to the smaller eastern unit, in a manner similar to the older interpretation of LAC-41 (the official IAU diameter excludes the main shadow-casting peak).
