McLaughlin (Mars)

Named after Dean B. McLaughlin - American astronomer (1901-1965).

McLaughlin is 90.92 km deep. The Mars Reconnaissance Orbiter has found evidence that the water came from beneath the surface. McLaughlin Crater, one of the deepest craters on Mars, contains Mg-Fe clays and carbonates that probably formed in a groundwater-fed alkaline lake. (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.
