Huygens Crater

The floor of the 450 km diameter crater named after Dutch astronomer Christian Huygens (1629-1695) shows an unusual texture. Smooth-topped mesas are scattered across a more rugged surface. The mesas are testament to a former smooth layer of material that is in the process of eroding away. Mega-ripples (a dune form) are located in some of the depressions in the image.
