Named after Clara Barton - American Red Cross founder (1821-1912).
Barton crater is a 54-km diameter crater on Venus. The floor crater is flat and radar-dark, indicating possible infilling by lava flows sometime following the impact. Barton's central peak-ring is discontinuous and appears to have been disrupted or separated during or following the cratering process. (wikipedia entry)
A crater is a circular depression likely created by an impact event. On Venus they are named after deceased women who have made outstanding or fundamental contributions to their field (if over 20 km). If smaller common female first names are used.
