No exposed lakes of frozen water

Shackleton Crater imaged by the Terrain Camera.
Exposed relatively-pure water-ice deposits are lacked on
the floor at the Terrain Camera's spatial resolution.

"Kaguya's Terrain Camera, which has the ability to detect illumination at one ten-thousandth of the intensity of radiation from the sun, imaged the bottom of the Shackleton Crater for the first time.... the terrain camera's 10-meter resolution allowed scientists to thoroughly investigate the reflectivity of the crater's bottom. The data confirmed that on the bottom surface, in permanent shadow, there is no visible water ice. If water ice does exist, it is likely to be an extremely small amount, possibly mixed with the soil or hidden in the surface..."
