THEMIS: Dunes and glacial deposits in Moreux Crater

Dunes and flowing debris in Moreux Crater (THEMIS_IOTD_20180530)THEMIS Image of the Day, May 30, 2018. Moreux Crater is located in the northern part of Terra Sabaea. The crater has a region of sand dunes on the crater floor, as well as features that are similar to glacial topography on Earth. (Note that the light is coming from the right.)

The glacial flows occur from both the crater rim and the central crater peak. Glacial activity creates fine scale materials, which means the source of the dune sands may be local, rather than materials blown in from outside of the crater.
