Hole Full of Shadow

We mostly observe areas of the Moon that are illuminated. but sometimes the lack of light creates patterns that are evocative and informative. Here the first rays of sunrise reflect brightly from the upper walls of Plato, and faintly from the exterior eastern rim. This emphasizes that the inner wall is steep and relatively smooth, accounting for the brightness, whereas the outer rim has a low slope covered with boulders and rubble.
