The delta region of the northern arm of Kasei Valles
The images show a view from the northwest to the southeast, with a protrusion into the delta region of the main northern arm of Kasei Valles. In the background, the 90-kilometre-wide Sharanov impact crater can be seen. Its immediate surroundings were able to withstand the erosion of the floodwaters; the crater rim towers above the valley lowland as a 2000-metre-high, terraced island.
 
In the former flood plain, flow patterns can clearly be seen that were caused by the erosive force of catastrophic floods. To the right in the foreground of the image, unusual outflow patterns can be seen that split up into numerous channels, recombining further on. In the centre of the lower edge of the image we can see a chaotic area consisting of numerous, separate, collapsed blocks of terrain. Bright dust tails can be seen on some small impact craters – here, dust and sand have been deposited on the lee side of the crater walls by the storms that predominantly blow from east to west, opposite to the direction of the earlier flood waters.
