Dark dunes sit on a rough, eroding sedimentary surface in the floor of an 83 km diameter crater. This crater is one of dozens in Noachis Terra, in the southern highlands of Mars, to have both dark dunes and an eroding surface. Note how the dunes seem to ignore the underlying rough surface in some cases, while in other places the dunes seem to have wrapped themselves around sharp knobs.
