These two buttes in the Elysium Basin exhibit many small dark streaks on their slopes. Each streak is the result of landsliding. Darker streaks appear to be younger than the brighter ones. Some of the small lumps at the base of these slopes (e.g., upper right) are big boulders. This Mars Global Surveyor Mars Orbiter Camera image was taken in April 1998, and is illuminated from the lower right.


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, CA. 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, CA and Denver, CO.
