Dunes are mounds of loose sand created by wind and are the most well known aeolian features. There are a varitety of types of dunes, depending on their shape. Most dunes share a common profile, or cross section, with a long shallow angle (stoss) facing into the wind, a peak (crest), and a steep lee side.

Dunes seldom exist by themselves, but as vast fields of many dunes.
