This image, taken with the High Resolution Imaging Science Experiment (HiRISE) camera, shows a mesa within the "Murray Buttes" area on Mars showing a complex fracture pattern (black arrow) protruding from the eroding rock. This mesa, which likely represents a remnant of crater floor sediments, lies on top of the sedimentary rocks of the Murray Formation. NASA's Curiosity rover will be exploring this formation.
