Concentric crater fill

A concentric crater fill (CCF)[1] is a landform where the floor of a crater is mostly covered with many parallel ridges.[2] It is common in the mid-latitudes of Mars,[3][4] and is widely believed to be caused by glacial movement.[5][6] Areas on Mars called Deuteronilus Mensae and Protonilus Mensae contain many examples of concentric crater fill.
