Jumbilation
south up image by Carmelo Mel Zannelli, Palermo, Italy
At this lighting Terra Manna is just a jumble of old craters, rilles, and odd spaces. It does include two rings of the Nectaris Basin but they are hard to identify. This view also reveals that one of the Gutenberg Rilles (in the center of the image) is not parallel to the others but actually crosses it - does that mean it has a different origin? At the top of the image, near the middle of scene, is an area that is much smoother than its surroundings - it must be lavas that are younger than the nearby terrain, which is likely since so much of the terrain seems to be secondary craters from the formation of the distant Imbrium Basin. A final surprise is the bold shadow-casting ridge near the bottom center of the image. Presumably it is all that remains of an older crater. Its lineation is radial to Nectaris suggesting that most of its rim was destroyed by the outrush of low angle ejecta from the formation of that basin. Doesn't it look similar to the ridges (like Boscovich) near Mare Vaporum that are radial to Imbrium?
