Large-scale crossbedding in the sandstone of this ridge on a lower slope of Mars' Mount Sharp is typical of windblown sand dunes that have petrified. NASA's Curiosity Mars rover used its Mastcam to capture this vista on Aug. 27, 2015.

The region southwest of Olympus Mons is covered with materials that have been eroded by the wind. Surface materials in this area indicate wind action in many different directions as shown in this image from NASA's Mars Odyssey.

The THEMIS VIS camera contains 5 filters. The data from different filters can be combined in multiple ways to create a false color image. This image captured by NASA's 2001 Mars Odyssey spacecraft shows part of Nili Fossae.

The faint dark lines in this image captured by NASA's 2001 Mars Odyssey spacecraft are caused by dust devils. As the dust devil travels along the surface it scours away the loose surface dust, revealing the darker surface beneath.

This image from an animation shows a patch of sandstone scrubbed with the Dust Removal Tool, a wire-bristle brush, on NASA's Curiosity Mars rover. This rock target is called 'Windjana,' after a gorge in Western Australia.

NASA's Mars Exploration Rover Opportunity captured this view of a wee crater, informally named 'Skylab,' along the rover's route. Based on the estimated age of the area's sand ripples, the crater was likely formed within the past 100,000 years.

Opportunity Beside a Small, Young Crater

A small channel enters this unnamed crater in Arabia Terra. There appears to be a small fan or delta formed where the channel meets the crater floor. This image was captured by NASA's Mars Odyssey on June 15, 2010.
