Quenisset (Mars)

Named after Ferdinand J. Quenisset - French astronomer (1872-1951).

Quenisset Crater is an impact crater in the Ismenius Lacus quadrangle on Mars at 34.6° N and 319.4° W. and is 138.0 km in diameter. Some close up images of the rim show old glaciers along the walls of smaller craters. Some glaciers are called lobate debris aprons. (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.
