This image was acquired to look for frost on these generally equator-facing slopes, which are visible in the shadows after enhancing the brightness levels. It is also a dramatic image given the low-sun illumination.

The color cutout has north down (illumination from the right side) so that downhill is down.

The University of Arizona, Tucson, operates HiRISE, which was built by Ball Aerospace & Technologies Corp., Boulder, Colo. NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Mars Reconnaissance Orbiter Project for NASA's Science Mission Directorate, Washington.
