Brashear Crater is an impact crater in the Thaumasia quadrangle of Mars, located at 54.14 S and 119.03 W. It is 77.45 km in diameter, and was named after John A. Brashear (1840–1920), an American astronomer. The name was approved in 1973.[1]

Sand Dunes[edit]

Many places on Mars have sand dunes. Some craters in Thaumasia show dark blotches in them. High resolution photos show that the dark markings are dark sand dunes. Dark sand dunes probably contain the igneous rock basalt.[2] Brashear Crater, pictured below, is one crater with dark dunes.
