EponymWilliam M. Sinton

Sinton is acrater in theIsmenius Lacus quadrangle onMars. Sinton crater lies in the northern hemisphere, south of the very large craterLyot[1] and west ofIsmeniae Fossae. It was named after Harvard astronomerWilliam M. Sinton. The name was approved in 2007.[2]

Description

[edit]

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.[3] Evidence of an icefield islineated valley fill (LVF) andlobate debris aprons (LDA) in the region. Some of this evidence can be seen in one of the images below.[4][5][6][7]

  • Channels just to south of Sinton, as seen by CTX camera. These were created when the impact occurred in ice-rich ground. Note: this is an enlargement of the previous image of west side of Sinton.

  • Old glacier just to north of Sinton, as seen by CTX camera. This is one of many glaciers in the region. Note: this is an enlargement of a previous image of west side of Sinton.
