Lucus Planum

Lucus Planum is a region on Mars, named after an albedo feature. Its name was approved by the IAU in 1997.^[1] The center latitude of the feature is 4.99 degrees S and the center longitude is 182.83 degrees.^[1] It lies just to the east and north east of the volcano Apollinaris Patera. Lucus Planum lies in both the Memnonia quadrangle and the Aeolis quadrangles. It is part of a region called the "Medusae Fossae Formation"^[2] Part of this region is covered with yardangs. They are formed by the action of wind on sand sized particles; hence they often point in the direction that the winds were blowing when they were formed.^[3][4] Views of yardangs in this region are shown below.
