THEMIS Image of the Day, August 3, 2018. This VIS image is located in the region between northern Terra Sabaea and Utopia Planitia.
This unnamed crater contains a small, dark dune field. Darkness suggests the dunes are dust-free, hence probably active at present.
The crater rim is heavily eroded and it appears that some downslope movement on the interior of the rim may have included a volatile component such as ice.
