Mars mission photos

The Proctor Crater, the ripples are composed of fine sand. The ripples have over time become coverd with dust which may account for the brighter tones.

The rock formation in this ' Stero Image' suggests it was formed using a process called 'Rhythmic Bedding'. The individual layers suggests the patterns arose from changes in the planet's tilt.

The dark branched features on the floor of Antoniadi Crater look like giant ferns, or fern casts. However, these ferns would be several miles in size and are composed of rough rocky materials.

Avalanches captured by HiRise on the surface of Mars. Material, including fine-grained ice, dust and possibly large blocks, have detached from a towering cliff and cascaded to the gentler slopes below.
