<p>HiRISE reveals small-scale shapes that often correlate with mineral units and provides information about stratigraphy (i.e., what’s on top and relative ages). This image was acquired for co-analysis with a spectrometer instrument also on our spacecraft called CRISM (Compact Reconnaissance Imaging Spectrometer for Mars). It shows polygonal units that match clay-rich areas. Plus, this region is colorful!
