This image taken by the Mast Camera on NASA’s Curiosity Mars rover just north of the “Kimberley” waypoint shows beds of sandstone inclined to the southwest toward Mount Sharp and away from the Gale Crater rim (top photo). The inclination of the beds indicates a build-out of sediment toward Mount Sharp. These inclined beds are interpreted as the deposits of small deltas fed by rivers flowing down from the crater rim to the north and building out into a lake to the south, where Mount Sharp is now.
