Clark (Mars)

Named after Alvan Clark - American optician-astronomer (1804-1887).

Dunes are visible on the floor of the crater, and dust devil tracks are in the area. The thin, dark streaks are dust devil tracks. (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.
