Oblique view northwestward across the Littrow Rille area of the eastern Sea of Serenity. A high Sun enhances the albedo contrast. Steep slopes in the highlands, crater walls, and rays are much brighter than the normal mare materials in the central Sea of Serenity at the top of the photograph. The ring of darker mare material and the still darker mantling material of the Littrow region are near the highlands margin.
