Pliny lunar crater can be of volcanic origin.







Pliny (43 km) is a polygonal crater, prominent, with a crumpled collar and a beautiful rocky floor. At its northern can be found Rimae Plinius, a set of three linear rilles, each about 100 km long, which looks like the cat's scratch. The crater is complex, with several central mountains. The appearance of this crater is changing considerably in different lighting conditions.


Pliny should be a good candidate for being volcanic in origin, not an impact crater. Pliny's central peak may be a volcanic cone surrounded by a ditch caused by the volcano. But we can not know this unless a geologist will fly there for a better study.

Promontorium Archerusia mountains and crater formation Dawes lies north-west and north east.
