If there was polar wander then the equator may have been somewhere else at the time. Another interesting thing about the image. If you look at the bottom of the non projected image the terrain appears to get sharply lower but the crater implies the water is flowing up the image. That implies the river might have come from quite a deep pool. If so then this was likely water that lasted a long time. If not, then how did the water flow uphill for long enough for all this to occur?

Also further down the image the craters become more indistinct as if they hit in water. If water did this then the air pressure must have been higher, and this would also apply to the river sites.
