This observation shows a lava plain near the Martian equator. The lava is superposed by a small, fresh crater that is itself surrounded by boulders that were ejected from the surface when the impact occurred.
There are dunes on the crater floor, indicating that the crater has been present long enough for wind to blown fine material into the crater and form the material into dunes.
