Crater Mead is the largest known crater on Venus. Named after Margaret Mead, the American anthropologist, it measures 280 km (168 mi) in diameter and is located north of Aphrodite Terra and east of Eistla Regio. Classified as a multi-ring crater, Mead's innermost ring is thought to be the rim of the original crater cavity. The presence of irregular, radar-bright crater ejecta crossing the radar-dark floor terrace and adjacent outer radar-bright ring suggests that the terrace floor region is likely down-dropped and tilted outward, forming a concentric ring-fault.
