Sinton Crater is a crater in the Ismenius Lacus quadrangle on Mars, located at 40.72°N and 328.35°W. It is 65.25 km in diameter and was named after William M. Sinton. The name was approved in 2007.[1]

Sinton Crater is believed to have been caused by an impact into an icefield. This impact melted ice and produced many branched valleys. Some of these can be seen in one of the images below.[2] Evidence of an icefield is lineated valley fill (LVF) and lobate debris aprons (LDA) in the region. Some of this evidence can be seen in one of the images below.[3][4][5][6]
