What a couple! (EDM)

This Extra Detail Magnification (or "EDM") has been obtained from a, just as usual, very beautiful and clear Contextual Image (or "CTX Frame", for short) of the Dwarf Planet 1-Ceres, taken by the NASA - Dawn Spacecraft on January, 25th, 2016, that showed us a pair of Unnamed Impact Craters located in the Northern Hemisphere of this Dwarf-Planet. The Wall of the older Unnamed Impact Crater (the lower one of the two) has partially collapsed where it adjoins the Rim of its younger neighbor (but we, as IPF, humbly disagree with this assumption). Can you tell us at least one reason why we, as IPF, disagree?


Furthermore, a few whitish Striations (Gullies, maybe?) can be clearly seen on the North-facing lower portion of the Inner Rim and Wall of the younger Crater.


The NASA - Dawn Spacecraft captured the Original Scene during its Low-Altitude Mapping Orbit (or "LAMO", for short), from an approx. altitude of 240 miles (such as about 386,2416 Km) above the Surface of 1-Ceres. The Image Resolution is roughly 120 feet (i.e. about 36,576 meters) per pixel (---> Picture Element).


This picture (which is a crop obtained from an Original NASA - Dawn Spacecraft's b/w and NON Map-Projected frame published on the NASA - Planetary Photojournal with the ID n. PIA 20647 - DAWN LAMO Image n. 107) has been additionally processed, extra-magnified to aid the visibility of the details, contrast enhanced and sharpened, Gamma corrected and then colorized (according to an educated guess carried out by Dr Paolo C. Fienga-LXTT-IPF) in Absolute Natural Colors (such as the colors that a normal human eye would actually perceive if someone were onboard the NASA - Dawn Spacecraft and then looked ahead, towards the Surface of 1-Ceres), by using an original technique created - and, in time, dramatically improved - by the Lunar Explorer Italia Team.
