Proctor Crater
Proctor is a large crater in the Noachis quadrangle of Mars. It was named in 1973 after Richard A. Proctor, a British astronomer (1837–1888).
Dune fields
The crater contains a 35 x 65 km dark dune field. It was one of the first sand dune fields ever recognized on Mars based on Mariner 9 images. The crater's dunes are being monitored by HiRISE to identify changes over time.
