Lunar #17: Vallis Schröteri

Aristarchus is an extremely bright crater in a wide dark mare environment. However, the local area of about 150 km size (the Aristarchus plateau) is lifted above the floor of Oceanus Procellarum. Aristarchus (40 km in diameter) is at the southeast corner of the plateau, Vallis Schröteri (160 km long and 10 km wide) is cut into the heart of the plateau.
