Proctor Crater is a large crater in the Noachis quadrangle of Mars, located at 48° south latitude and 330.5° west longitude. It is 168.2 km in diameter and was named after Richard A.Proctor, a British astronomer (1837–1888).[1] The crater contains a 35 x 65 km dark dune field.[2][3] It was one of the first sand dune fields ever recognized on Mars based on Mariner 9 images.[4] The crater's dunes are being monitored by HiRISE to identify changes over time.[5]
