Sinuous rilles formed from massive outpourings of molten lava. This example originates on the Aristarchus Plateau and is the largest on the Moon; it extends for over 150 km and is 4 km wide and over 500 m deep at its midpoint. It is also distinguished by a rille within a rille, telling the story of an initial massive eruption of very fluid magma that carved the larger channel and then later a smaller eruption that formed the smaller channel.
