	Layers in Uzboi Vallis Deposits on the floor were emplaced when drainage was blocked by the formation of the rim of Holden Crater.

	Sulfates in Aram Chaos This image is from Aram Chaos, a large crater connected to the Ares Vallis outflow channel.

	Crater Floor Fan The material was transported into the crater through a valley, likely by running water.

	Layered Rocks in Iani Chaos The rocks here are light-toned, and have dark low patches which are likely a thin cover of wind-blown sand.

	Slope Streaks in Unnamed Crater in Amazonis Region Slope streaks are thought to be small-scale dust avalanches that usually are dark when they form but fade into the background over time.

	Buttes and Knobs in Cydonia Region This region gained notoriety when Viking imaged a landform that looked like a face.

	Widened Gully Alcoves This image shows the west wall of a southern hemisphere crater with gullies having very wide alcoves.
