    A Valley Within a Valley
    This valley on the Aristarchus Plateau is the largest sinuous rille on the Moon. It is more than 150 kilometers (93 miles) long, 4 kilometers (2.5 miles) wide, and 500 meters (1,640 feet) deep. Sinuous rilles are channels carved by eruptions of very fluid lava. As the eruption that formed this large rille waned and the amount of lava decreased, the smaller channel within it formed.
