Description
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 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.[4][5][6][7]
