Part of Candor Chasm in Valles Marineris, Mars, from about latitude -9 degrees to -3 degrees and longitude 69 degrees to 75 degrees. Layered terrain is visible in the scene, perhaps due to a huge ancient lake. The geomorphology is complex, shaped by tectonics, mass wasting, and wind, and perhaps by water and volcanism.
