Yardangs are common on Mars.
 They are generally visible as a series of parallel linear ridges.
 Their parallel nature is thought to be caused by the direction of the prevailing wind.
 Two HiRISE images below show a good view of yardangs in the Aeolis quadrangle.
 Yardangs are common in the Medusae Fossae Formation on Mars.
