In the crater on the far right there is something darker than the surrounding material  shade ? but I cannot see what is the cause of the shade ? water I doubt very much !

 The Sun is coming from the left and the crater is bowl shabed so the left side of the crater isn't getting any sun so it is shaded but the right side is not shaded and gets sun.
I hope this explains it for you. You can try this at home by holding a small soup bowl next to a lamp or some light and you can see the shadowed area change by raising or lowering it and moving it around.
