We identify eight sets of topographically inverted, branching deposits that we interpret as deltaic in origin. This interpretation is based on our observation of a topset to foreset transition in the dip of stratal surfaces, the proximity to two other coastline deposits (base-level controlled incised valleys and another delta system), and morphologic and geometric similarties to the other deltaic system identified at Aeolis Dorsa. This work is important because it could be evidence for a Northern Hemispheric Ocean!
