This image covers most of an impact crater about 6 to 7 kilometers wide. Partway down from the crater rim is a prominent bright layer of bedrock.
The full-resolution color data shows three distinct bedrock colors: yellow, light blue-green, and dark blue in enhanced infrared colors. (North is down in the cutout.) These layers must correspond to different types of rock that were deposited as nearly flat-lying sheets, perhaps a combination of lava flows and sediments.
The relatively blue colors in HiRISE infrared often correspond to minerals like olivine and pyroxene that are common in lava.
