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.
