Iani Chaos is one of many regions east of Valles Marineris characterized by disrupted or chaotic terrain. The shape of this terrain is dominated by large-scale remnant massifs, which are large relief masses that have been moved and weathered as a block. These are randomly oriented and heavily eroded. Context Camera images show there are light-toned deposits here amongst the chaos blocks. (NASA/JPL-Caltech/University of Arizona)]]>
