This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows wind-sculpted remnants of layered sedimentary rock that once completely covered the northwestern floor of Henry Crater, an ancient impact basin located at 11.7°N, 336.4°W. These landforms, shaped somewhat like inverted boat hulls, are "textbook examples" of a wind erosion form known as a yardang. The image covers an area 2.3 km (1.4 mi) wide; sunlight illuminates the scene from the left.
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.
