– Equatorial Gullies

Gully-like landforms, or ravines, are most common in the middle latitudes of Mars, but also occur in polar and equatorial latitudes.

– Frost in Dune Shadows

The low sun angle creates large shadows from these dunes, making for a dramatic picture.

– Dunes Streaming through Hills

This dramatic image show dark rippled bodies of sand, sometimes in the form of dunes, streaming through Ganges Chasma.

– Craters in an Icy Surface

The crater in the center of this image is unusual because there is a wide, flat bench between the outer rim and the inner section, making it appear somewhat like a bullseye.
