Angular "Albedo Arc" (Enhanced Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunar Explorer Italia)

Caption NASA:"A distinct Albedo difference is visible in this image, separating lighter, smoother ground in the North from darker, older Terrain in the South. This contrast is likely indicative of a compositional difference between the two Terrains. Although at first glance this feature seems angular, the Albedo change most likely marks the edge of an extremely degraded Impact Basin (---> Crater)".
