aristarchus & schröter's valley

Winding through the uplands to the north-west of the bright crater Aristarchus, the distinctive Schröter's Valley - the largest sinuous rille on the Moon - resembles a dry river-bed. It runs some 160km from the flooded crater Herodotus. It may be a collapsed lava tube.
