Viscous, lobate flow features commonly found at the bases of slopes in the mid-latitudes of Mars, often associated with gullies. These are bound by ridges that resemble terrestrial moraines, suggesting that these deposits are ice-rich, or may have been ice-rich in the past.

Rough spherical features in an area called Yellowknife Bay. These features are interpreted as concretions, implying they formed in water that percolated through pores in the sediment. Spherical concretions have previously been discovered in other rocks on Mars.

A rock outcrop called Link pops out from a Martian surface. Rounded gravel fragments, or clasts, up to a couple inches in size are in a matrix of white material. The outcrop characteristics are consistent with a sedimentary conglomerate, or a rock that was formed by the deposition of water and is composed of many smaller rounded rocks cemented together. Scientists enhanced the color in this version to show the Martian scene as it would appear under the lighting conditions we have on Earth.
