Montes Alpes is a mountain range in the northern part of the Moon's near side. It was named after the Alps in Europe; the name was confirmed by the International Astronomical Union in 1935. The range thus crosses the lunar prime meridian, and is partially illuminated and partially in shadow during first and last quarters. The center of the range is at 48.36°N, 0.58°W, and has a diameter of 334 km.
The Alpes range was part of the middle ring of the multi-ringed Imbrium Basin. The other mountain ranges around the Imbrium Basin (Montes Caucasus, Montes Apenninus, and Montes Carpatus) were part of the outer ring. The Alpes, being part of the middle ring, thus have a shorter radius to the center of Imbrium than the other ranges of the basin.
The northwestern third of the range is separated from the remainder of the mountains by the Vallis Alpes, a wide rift valley that extends from a narrow cleft in the Montes Alpes to the northeast, reaching the edge of the Mare Frigoris. The total length of this formation is about 166 km, and it reaches a maximum width of 10 km. Running down the center of this valley is a narrow cleft which is not observable through smaller telescopes. Sunrise and sunset in this area occur before the respective lunar quarters.
