View of the mouth region of Kasei Valles
View of the estuary of Kasei Valles on Mars. Ancient megafloods carved out this region before finally flowing into Chryse Planitia. The Worcester impact crater – the largest crater visible in the image section with a diameter of around 25 kilometres – has resisted the erosive force of the flooding. In some places, its ejecta material has been worn away; downstream it has largely survived. As a result, a streamlined island was formed, which still denotes the flow direction (west to east). North is to the right in the image.
