Sinuous rille (A) is unusually shallow for its width and has probably been mantled or filled since its formation. The entire area shows evidence of an older mantled and subdued topography on which secondary craters (B) from the 40 km primary crater Aristarchus (to the southeast) have been superposed. Among the mantled features are a straight rille (C), craters (D), and numerous polygonal depressions (E), which may be subsidence features, possibly caused by withdrawal of magma at depth, or differential compaction of lava over small highland blocks. The Aristarchus plateau is to the southeast.    C.A.H.
