This image captured by NASA's 2001 Mars Odyssey spacecraft shows sand dunes on the floor of an unnamed crater in Arabia Terra.

Dunes

This mantle observed by NASA's Mars Reconnaissance Orbiter is thought to be deposited as snow during periods when the angle of the tilt of Mars' rotational axis-called obliquity-is much higher, which last happened around 10 million years ago.

A delta deposit sits on the floor of this unnamed crater in Arabia Terra, as shown in this image from NASA's 2001 Mars Odyssey spacecraft. The channel that created the delta dissects the crater rim.

The volcanic flow in this image from NASA's 2001 Mars Odyssey spacecraft appears to have flowed in one layer. The surface texture is blocks of lava which cooled and still moved on molten lava below, producing the plate-like texture.

The main agent of erosion on Mars today is the wind. Wind has sculpted the surface in this region into a set of hills and valleys called yardangs on Earth. This image is from NASA's 2001 Mars Odyssey spacecraft.

This image captured by NASA's 2001 Mars Odyssey spacecraft shows a portion of the huge dune field located at the north polar cap. As spring continues to deepen, the dunes are becoming darker and darker as they lose their winter frost cover.
