This image covers diverse surface units on the floor of eastern Coprates Chasma in eastern Valles Marineris.
The bedrock has diverse minerals producing wonderful color contrasts . In over 10 years of orbiting Mars, HiRISE has acquired nearly 50,000 large images, but they cover less than 3 percent of the Martian surface.
