The grandest mountains on the moon are the Apennines. They range for more than 600 km along the eastern shore of Mare Imbrium. Many peaks reach 5 km high. Mons Huygens reaches 5.4 km. At the southern end lies the 60 km wide crater Eratosthenes. Its steep walls plunge 3.5 km to the floor. You can see an ancient flooded crater below and ridges in the lava as well. Archimedes to the west of the mountains is 83 km wide. The rim rises 2.2 km above the flooded floor. Apollo 15 landed on the west side of Mons Hadley. This was the first Apollo mission to bring along a moon buggy.
