A number of mare related features are present in this oblique view
looking north across a mare surface between Mare Imbrium and Oceanus Procellarum.
A broad mare arch is visible in the foreground. As it is followed toward
the northwest the arch gives way to a series of small ridges, which then
converge on an unusual sinuous chain of craters, elongate ridges, and elongate
depressions. This sinuous chain leads into a large arcuate elongate depression
at the boundary between the highlands and the mare. Similarity of parts
of this structure to parts of some sinuous rilles, for example, Rima Hadley,
suggests that its strange morphology may be a poorly understood variation
of a lava channel, possibly a partially collapsed lava tube.
