Dawes Crater is located in the Sinus Sabaeus quadrangle of Mars, at 9.2 S and 38 E.[1] It is about 191 km (119 mi) in diameter, and was named after William R. Dawes, a British astronomer (1799–1868)[1] who was ahead of his time in believing that Mars only had a thin atmosphere.

Dawes presumed that the atmosphere of Mars was thin because surface markings on the planet could easily be seen.

As craters get larger (greater than 10 km in diameter) they usually have a central peak.

[3] The peak is caused by a rebound of the crater floor following the impact.
