Shackleton LROC

Oblique view of the rim of Shackleton crater (21 km diameter, located 89.66°S, 129.20°E) seen in an image captured by the Lunar Reconnaissance Orbiter Camera. While no location on the Moon stays continuously illuminated, three points on this rim remain collectively sunlit for more than 90% of the year. These points are surrounded by topographic depressions that never receive sunlight, creating cold traps that can capture ices.
