Geological Chronicle
Mont Blanc is located on the western edge of the Montes Alpes range, near the shore of Mare Imbrium. With a diameter of 21.57 kilometers, the mountain reaches 3.7 to 3.8 kilometers above the adjacent plains of Mare Imbrium, and sits 1.12 kilometers above the lunar zero-elevation sphere of radius 1737.4 kilometers.
Johann Hieronymus Schröter proposed naming the feature after Mont Blanc, the highest mountain in the terrestrial Alps. The International Astronomical Union approved the name in 1935. It remains the only summit in Montes Alpes with a proper name and the only extraterrestrial mountain whose international designation contains the French word "Mont" rather than the Latin "Mons".
Despite earlier statements that lunar Mont Blanc was the highest mountain in its range, measurements from the Lunar Reconnaissance Orbiter showed that it ranks third. The summit is 600 meters lower than the highest peak in Montes Alpes and about 100 meters lower than the second.
