Wegener (Mars)

Named after Alfred L. Wegener - German geophysicist (1880-1930).

The pictures show dunes defrosting. Dark spots appear on dunes in the higher latitudes of Mars. In these spots mineral grains may be covered with a thin film of water that may affect chemical weathering of minerals and may help possible Martian organisms to survive. (wikipedia entry)

A crater is a circular depression likely created by an impact event. On Mars large craters are named after deceased scientists, writers and others who have contributed to the lore of Mars. Small creaters (less than 60km) are named after small towns and villages.
