THEMIS: Gullies in Noachis Terra

Crater rim gullies in Noachis (THEMIS_IOTD_20181210)THEMIS Image of the Day, December 10, 2018. Numerous channels, also called gullies, dissect the rim of this unnamed crater in Noachis Terra. (Note that the lighting in this image comes from the lower right.)

At upper right lies a small field of active dunes — dark because they are dust-free, and active because sand grains kick off dust when they move.
