Can we see layering in the scarps of this mesa? The larger circle here formed as a scarp retreated away from a previous crater’s raised rim. The terrain has a lot of variety and elements, including dark, spotty surfaces (big boulders?). Was this below sea level in some hypothetical northern plains-covering ocean? Is there any evidence for sediment in that ocean basin here?
