This image, taken with the High Resolution Imaging Science Experiment (HiRISE) camera, shows the transition between the "Murray Formation," in which layers are poorly expressed and difficult to trace from orbit, and the hematite ridge, which is made up of continuous layers that can be traced laterally for hundreds of meters. Orbital data shows that this change in bedding style between the Murray formation and the hematite ridge is also accompanied by a major change in layer composition. NASA's Curiosity rover will be exploring this formation.

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