Unusually-looking Unnamed Crater (Saturated Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunar Explorer Italia)

Caption NASA:"At one time the Floor of this Unnamed Crater located to the West of Hellas Basin, was completely filled with material from Rim to Rim. As this image shows, part of that fill material is being removed. The hole that is formed shows that the fill material was layered and a very rough surface is located at the bottom of the hole".
