Mont Blanc
|
Lat: 45.0°N, Long: 1.0°E, Diam: 25 km, Height: 3.6 km, Rükl: 12 |
LO-IV-115H Mont Blanc is to the right of center, and the 5-km circular crater in the upper left is Alpes B. The direction of the sunlight is roughly parallel to the Lunar Orbiter scan lines. The summit of Mont Blanc is casting the longish shadow in the 10 o'clock direction. The location of the summit can be found by tracing back from the shadow tip in the reverse direction.

Although there seems to be nothing in the LPI's Apollo Images Search for Mont Blanc and adjacent peaks in the Montes Alpes, there ARE orbital Apollo photographs of those peaks! For example: Fairchild-Metric image AS15-M-1538 which shows these peaks at the centre of the curved horizon! (north of Aristillus). Research Danny Caes.

Additional Information
- The location and diameter given in the title line are taken from the IAU Planetary Gazetteer, but they correspond to a circle to the southeast of the peak. The correct coordinates of the summit are closer to 45.4°N / 0.3°E. - JimMosher
- Depth data from Kurt Fisher database
- Viscardy, 1985: 3.6 km
- Cherrington, 1969: 2.8 km
- Height was measured as 3.2km + or - 200m Boint, 2001.- fatastronomer
- The shadows in LO-IV-115H are not suitably placed for a height measurement: they indicate only that the summit is about 2500 m above the terrain on which the shadow tip falls, which is itself well above the mare. The various images in the Consolidated Lunar Atlas that show shadows cast onto the mare to the west indicate a height in the range 3700-3900 m. Elger's estimate of 3660 m is consistent with Plate A5. - JimMosher
- Close beneath the eastern foot of Mont Blanc, Schroter perceived, 1789, September 26th, on the dark side of the moon, a small speck of light, like a 5 Magnitude star to the naked eye, which having been verified in position, and kept in view for fully 15 minutes, disappeared irrecoverably: the round shadow, sometimes black, at others grey, which he subsequently found in the day-side in or near its place, was probably nothing new. Strange to say, 1865, January the 1st, Grover recovered this bright spot, or one very near its site, with only 2 Inch of aperture, and saw it unchanged like a 4 Magnitude star to the naked eye, but rather larger, for fully 30 minutes.

Nomenclature
- Named for terrestrial mountain in Alps. (Mont Blanc)
- According to Whitaker (p. 218), this name was introduced by Schröter, and it was adopted in that form in the original IAU nomenclature of Blagg and Müller. It is one of the few traditional peak names that was not later Latinized to "Mons".
