Venus - Magellan

Markham Crater, Venus and run-out flows

Magellan radar image of Markham crater, Venus. This 75 km diameter impact crater was formed near the summit of a volcano which allowed the long downslope run out of impact melt. The ejecta patterns and position of the central peak indicate an oblique impact at an angle of 10 to 20 degrees from the northwest (north is up). (Magellan C2-MIDR 00N131;1,framelet 40)
