Largest Mountain Range on the Moon

Montes Apenninus forms a sharp, rugged rise at the edge of the Mare Imbrium. The total length of the range is about 600 km (370 mi), with some of the peaks rising as high as 5 km (3.1 mi). The entire area to the southeast of Montes Apenninus – its backslopes – is shaped by ejecta deposited during the violent uplift of the mountains.The Montes Apenninus range forms the southeastern border of the large Mare Imbrium lunar mare and the northwestern border of the Terra Nivium highland region. It begins just to the west of the prominent crater Eratosthenes, which abuts against the southern face of the range. To the west of these mountains is a narrow gap where Mare Imbrium in the north joins Mare Insularum to the south.
