|This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a crater formed in light-toned, layered, sedimentary rocks in Meridiani Planum. This crater is located approximately 55 kilometers (~34 miles) southwest of the Mars Exploration Rover, Opportunity, site. Erosion of sedimentary rock layers around the crater rim has caused an uneven retreat, resulting in the formation of U-shaped alcoves where undermining and collapse have occurred. Dark material in this scene is probably sand and granules, similar to the dark surfaces explored by the Opportunity rover.|

Malin Space Science Systems and the California Institute of Technology built the MOC using spare hardware from the Mars Observer mission. MSSS operates the camera from its facilities in San Diego, California. The Jet Propulsion Laboratory's Mars Surveyor Operations Project operates the Mars Global Surveyor spacecraft with its industrial partner, Lockheed Martin Astronautics, from facilities in Pasadena, California and Denver, Colorado.
