Western Chryse Planitia. The west side of Chryse Planitia had been extensively sculpted by flow from Maja Vallis, which is situated just to the left of this mosaic. Flow diverged across the gently sloping plains of Chryse Planitia to form the sculpted features seen in this mosaic. Ridges, similar to those on lunar maria, appear to have partly dammed or diverted flow to form a variety of scour patterns. The image is about 360 km across.
