Shadows and Peaks Along Alpine Valley

This high-resolution lunar image showcases the dramatic contrast between shadowed and sunlit terrain along the terminator, revealing an intricate interplay of impact history and geological evolution.

Below, the Cassini crater, partially flooded by ancient lava, marks the transitional boundary between the rough highlands and the smooth plains of Mare Imbrium. The rugged Lunar Alps stretch across the frame, with the sinuous Alpine Valley cutting through them—a rift possibly formed by tectonic forces or subsurface magma movement. This image is a striking testament to the Moon’s violent past and the forces shaping its ever-scarred surface.
