This image, at the northwestern edge of the massive Antoniadi Crater, shows us an exposure of sediment from a possible fluvial ridge (inverted channel). This sweeping feature terminates to the east in a sediment fan. Our science goal is to inspect the sedimentary depositional structures in this area of the crater. Antoniadi is 394 km wide and likely contained rivers and lakes.
